Recovery :: Several AG For One SharePoint Farm / How Many Listeners
Sep 22, 2015
I have to install several AG on a cluster for a whole SharePoint production farm, it's a nice to have (1 AG for Search database, 1 AG for Profil database, 1 AG for Content database, 1 for applicatif, etc...) We have 2 Front End load balanced, 1 application server and 3 SQL HADR: 2 nodes on synchrone (sql 2014 enterprise licence) and the 3rd asynchrone (standard licence).
The SharePoint farm is configured with the SQL Alias on the primary node, then if there is a failover on node 1, I must move the sql Alias to the second node manualy, unless I'd configured this Alias to point on the AG listener of the availability group in order to use the automatic failover. But as we have several AG, should I create one listener per each AG?
And which AG listener should I have to configure on the SQL Alias then ?

I have a web server that is on our DMZ subnet and I have a sql 2014 database server with Always on Availability Groups that is on our internal domain subnet.The failover cluster is on the internal domain subnet as well. I am trying to connect a web application, that is working off the .net 2.0 framework, to an SQL Server 2014 database using the Always on Availability Group Listener.Â
The connection strings works perfect with the named instance of the sql server but when I try to use the Availability Group listener it timed out. I did some research online and was led to believe that increasing the connection time would resolve it. I did that and got a different error pertaining to a successful connection but an error occurred during the login process (Provider: TCP Provider, error: 0 - The specified network name is no longer available.)Â
I just want to connect to an Availability Group Listener on the domain subnet. I have rules in the firewall to allow all services for the IP of the Listener. I switch back to the named instance of the same server and it works flawlessly. I have also connected to the Listener while running the application on the same subnet as the sql server without an issue. I have tried the IP instead of the Listeners name and still received the same error on the DMZ subnet. I'm running on Windows Server 2012 R2 on all servers.
The Web Server is using IIS 8.5..All Physical Machines except the replicas and webserver are virtual machines.All Static IPs involved.As mentioned all SQL Servers are 2014.

I have an old sharepoint db (SQL Server 2000 Standard edition). What I need to try to recover is the data in log backup files from the docs table. I need to see if there is a way to get any data in the log backups from columns dirname, leafname and content. The column content is an image type which old documents (word, excel...). I don't have a full log chain since the last full restore so any data I can get out of the logs is better than nothing. I really just need to get the image files stored in the column content and place them in a shared directory for the users and let them see what they can use.

I have a situation where I have two servers in SQL Server 2012 R2 AlwaysOn Availability Group. One is primary and the other one being secondary.  I am only running SharePoint Database on it.I have run out of space on the primary server and about to run out of space at the secondary server. I have tried shrinking database transaction log files, but it returns an error that it cannot be shrunk as the database is in the AlwaysOn Availability Group.
Questions:
1. Several forums suggest that databases need to taken out of AlwaysOn Availability Group in order for the shrinking to work properply?
2. Would it have any impact on the database if it is taken out of availability group and then added back?

I think theres something I'm missing about AG listeners. My test config is 1 SharePoint WFE & 2 SQL servers configured in an AAG.WFE, SQL1 & SQL2Â servers are all on the same subnet.On the WFE, I configured an alias called SP15 to be used for the SQLÂ servers. If I failover from SQL1 to SQL2 I just need to change where the alias is pointing on the WFE. So why do I need a listener? This works fine, albeit manually.I have read on some posts that an automatic failover process is possible. How can I add a 2nd IP address to the listener when both SQL servers are on the same subnet? The GUI doesn't seem to allow this.

I have four instances and each instance have its own Availability Group with its own listener.
Would like to know if you can have one listener for multiple Availability groups?

Currently we have an AlwaysOn AG set up with a listener running on port 1433 (underlying instances are on a non default port). Great, no problems there.If we set up a second AG on the same instance with its own specific listener, can this new listener also be configured to use port 1433?

I have built a SQL 2014 Always on Cluster. I need to create three Availability groups and listeners in the same instance. Do I need 3 separate IP address for each listener or one IP address can be shared for all 3 Listeners ?

I am developing a web app that uses a SQL Server backend and will be served by a Web Farm at some point in the future. Can anyone give me some guidance at to what the common architectual considerations are when using SQL Server with a Web Farm? Initially, would it be allright to continue to have a single SQL Server on the network, with several webservers connecting to it instead of just one, or would this be a big performance nightmare? Eventually, since the goal of using the Web Farm would be to reduce individual server load, I would think having multiple SQL server instances would be preferred. Is this even done in the real world? I'm not a dba, so I'm not quite sure of the how multiple instances would be synchronized so that they held the same data and how applications on varying web servers would know to connect to one or another (by varying the connections string, perhaps). Can anyone give me any guidance? Thanks!

I get the following error when I try to navigate to a report/model/data source, stored in a Sharepoint Document Library using a Sharepoint URL based on an Extranet or Intranet zone - but it works OK using the url for the Default zone:
System.Web.Services.Protocols.SoapException: The specified path refers to a SharePoint zone that is not supported. The default zone path must be used. ---> Microsoft.ReportingServices.Diagnostics.Utilities.SecurityZoneNotSupportedException: The specified path refers to a SharePoint zone that is not supported. The default zone path must be used.
Is this a limitation of the SQLRS-WSS3 integration or is there a workaround?
Many thanks to anyone who can help!

Our topology:
Internal corporate network domain utilizing Integrated Windows Authentication between local workstations and the web and database servers. (domain similiar to: http://reports.ourdomain.com)
Machine #1: Windows 2003 Server w/SQL Server 2005 (SP2 and hotfixes applied) running SSRS.
Machine #2: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Machine #3: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Device #1: Arrowpoint load balancer for Machines #2 & #3 (w/sticky sessions).
We recently added 2 web servers and configured them to load balance the web requests to a seperate SQL Server machine. (the load balancing is done thru an Arrowpoint device not Microsoft NLB)
The installation of reporting services (on Machine #2 & #3) went smoothly and the configuration was a breeze. But we could not access the "http://reports.ourdomain.com/Reports" directory for reporting services on the 2 web server machines. We received the "401.1 - Unauthorized" http error.
Since we were using a domain name to access the report server we made sure to update the <URL> tag in the config files.
File location 1:
C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportManagerRSWebApplication.config
<ReportServerUrl>http://reports.ourdomain.com/ReportServer</ReportServerUrl>
File location 2:
C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportServer
sreportserver.config
<UrlRoot>http://reports.ourdomain.com/reportserver</UrlRoot>
We still received the error, so then we added a couple of entries to the HOSTS file on each web server:
File location -->
C:WINDOWSsystem32driversetcHOSTS
In order for the load balancers to "see" themselves from the domain reference we had to update the HOSTS file
on each web server to have the domain name "reports.ourdomain.com" point to the IP Address of the specific web server.
(we also added the IP of Machine #1 just to be safe):
MACHINE #2's HOSTS file:
127.0.0.1 localhost
10.10.0.1 Machine1
10.10.0.2 reports.ourdomain.com #IP of Machine2
MACHINE #3's HOSTS file:
127.0.0.1 localhost
10.10.0.1 Machine1
10.10.0.3 reports.ourdomain.com #IP of Machine3
Then the web servers were able to authenticate the users using IWA and NTLM
and we could access the report servers normally. Even the the scheduled reports
were being load balanced and emailed from the web servers which we didn't
expect to happen. (pretty cool!)
I hope this helps someone else as it tooks us about 4 days to figure this out.

Does anyone know the location of Microsoft.ReportingServices.SharePoint.UI.WebParts.dll after you install the web part? I am wondering if I can inherit from this web part to wrap some other functionality into it. I know that i see it in the GAC buyt can't seem to find it so I can look at the assembly using reflector.
Also, how easy is it to pass in parameters to the Report Viewer?
Thanks!

Since I wasn't getting any replies with answers or suggestions to my initial posting, I figured I would continue to list the problems and solutions I've encountered while trying to setup and utilize SharePoint integration mode, and read data from SharePoint with SSRS reports (developed in VS2005). Hopefully this is helpful to anyone that is also trying to learn all this stuff and figure it out.
(Single server - W2K3R2_SP2 as: DC / SQL2005 Standard / MOSS2007 Enterprise - see the bottom of this posting for the steps I took to set that up)
Note: After I get this to work, I intend to post my experiences for setting up SharePoint Integration with SQL and SP on separate boxes.
1. In the new reporting section under SharePoint application management in the Central Admin Console, the Grant database AND Set Server Defaults work when using the domain admin account, but not when using the SQLSPS service account I used to setup both SQL and SharePoint. Why can't I use the service account? Is the domain admin account now going to be used as a service account for accessing the sharepoint database?
This question remains unanswered as of yet.
2. Reporting Services configuration tool shows Sharepoint integration as red x when I create a new database in integration mode. (the service account SQLSPS and the Server object are members of the group WSS_WPG). If I switch back to native mode (the original reportserver database), the red x goes to a blue exclamation instead. Using Service Credentials or Windows credentials (as either the service account SQLSPS or as domain admin) doesn't change anything.
RESOLVED by using a domain user account for the ReportServer WebApp. Even though everything is installed on the same machine, it seems using the default of NETWORK SERVICE wasn't acceptable. Possibly because SharePoint is configured to allow additional machines in the farm?
3. http://servername:8080/reportserver will display Report Server information as it did before the integration on port 80, but http://servername/reportserver doesn't display anything through SharePoint.
Resolved. I needed to define a repository before I could view it (go figure). When I created a sharepoint site based on a report center template, created a data connection library and report library, and then referenced that by http://servername/sites/myReportCenterSite/myReportLibrary, I was able to see the equivalent of http://servername/reports (which is now disabled due to integration mode).
4. Unable to deploy to new report center sharepoint site I mention above using Visual Studio. I kept getting "A connection could not be made to the report server http://servername/sites/ReportCenter. Server was unable to process request. The request failed with HTTP status 503: Service unavailable (System.Web.Services). In Visual Studio, the project properties were: TargetDataSourceFolder = http://servername/sites/myReportCenterSite/myDataConnectionLibrary, TargetReportFolder = http://servername/sites/myReportCenterSite/myReportLibrary, TargetServerURL = http://servername/sites/myReportCenterSite/
Found these errors in the event logs on the server.
Event Type: Warning
Event Source: W3SVC
Event ID: 1021
Description:
The identity of application pool, 'ReportServer' is invalid. If it remains invalid when the first request for the application pool is processed, the application pool will be disabled. The data field contains the error number.
Event Type: Warning
Event Source: W3SVC
Event ID: 1057
Description:
The identity of application pool 'ReportServer' is invalid, so the World Wide Web Publishing Service can not create a worker process to serve the application pool. Therefore, the application pool has been disabled.
Event Type: Error
Event Source: W3SVC
Event ID: 1059
Description:
A failure was encountered while launching the process serving application pool 'ReportServer'. The application pool has been disabled.
RESOLVED the issue by changing the Application Pool used by reporting services from ReportServer to DefaultAppPool and changing the account DefaultAppPool used from NETWORK SERVICE to my service account SQLSPS. I have no idea why ReportServer is invalid, it was set to use the service account SQLSPS the same as DefaultAppPool is. Perhaps the reporting services add-on makes a change to invalidate this?
5. Attempting to read a SharePoint list using a SSRS report. This should be fun.
First, created a new custom list in the ReportCenter SharePoint sites I've been using and called it myCustomList. I added one item with a title of myCustomListItem1. I don't know if I need to do more than that for a simple test of reporting or not yet.
Second, configured new shared data source. Name = myCustomList1DataSource, type=XML, Connection String = http://servername/_vti_bin/lists.asmx (this URL is viewable in IE), Using Windows authenticaion.
Third, in VS2005 on a workstation in the domain, create new report item (report1.rdl). New dataset for report; Name=Report1DataSet, Data Source=myCustomList1DataSource (Shared), Command type = text, Query String = [See Queries and associated errors below]:
Initial query obtained from: Connecting SQL Reporting Services to a SharePoint List (David Wise)
http://www.sharepointblogs.com/dwise/archive/2007/11/28/connecting-sql-reporting-services-to-a-sharepoint-list-redux.aspx
Note: Queries when executing the dataset (which errors out) and when executing a query in CAML Viewer for the same information (which does work just fine) both initially return 401.1 and 401.2 errors (as viewed in Fiddler). Since the CAML query works, I have not tracked this down yet.
A. Original format from posting
<Query>
<Method Namespace=http://schemas.microsoft.com/sharepoint/soap/ Name="GetListItems"/>
<SoapAction>
http://schemas.microsoft.com/sharepoint/soap/GetListItems
</SoapAction>

- Advanced information from the error => 'http' is an unexpected token. The expected token is '"' or '''. Line 2, position 19. (System.Xml)
B. Changed: Placed the namespace URL in quotes (also tried with and without / in namespace after /soap)
<Query>
<Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems"/>
<SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems

- Advanced information: <faultstring>Server did not recognize the value of HTTP Header SOAPAction: http://schemas.microsoft.com/sharepoint/soap/GetListItems/.</faultstring>
C. Try the query string that seems to work for Stramit CAML Viewer to read myCustomList

<Query xmlns="http://schemas.microsoft.com/sharepoint/soap/">
<OrderBy>
<FieldRef Name="ID" />
</OrderBy>
</Query>
Also tried
<Query xmlns="http://schemas.microsoft.com/sharepoint/soap/">
</Query>
And tried entering no query...
Parameter; Name => listName, Value => =myCustomList (also tried Value => myCustomList) (no equal sign)
Clicked "!" to execute, and got prompted to define the query parameters
Entered Name => listName, Value => myCustomList
- Gets this error: "failed to execute web request for the specified URL (Microsoft.ReportingServices.DataExtensions)."

RESOLVED. Went back to the query used in B above, and mysteriously it works now. This could be the "funny things happen" symptom I've been reading about. We'll see if it continues to function.
Here's what I've learned so far on Issue #5:
1. XML is confusing. XmlDP is even more confusing...whatever that is. Apparently it's new to/with Reporting Services in SharePoint integration mode?
2. There is far too little documentation regarding XmlDP and querying SharePoint lists from SQL Reporting Services.
3. According to http://msdn2.microsoft.com/en-us/library/ms159741.aspx: You must use the generic query designer to create the query. The query is not analyzed to identify parameters; therefore you must create parameters through the Parameter tab on the Dataset dialog box.
Tried this query:
<Query>
<SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction>
<Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems" />
<Parameters>
<Parameter Name="listName">
<DefaultValue>myCustomReport2</DefaultValue>
</Parameter>
<OrderBy>
<FieldRef name="ows_Date" />
</OrderBy>
</Parameters>
</Query>
I was still prompted for the listName and the list returned with ows_Date still out of order. So maybe that proves this statement is true?
<translation: why make it convenient when it's already [somewhat] functional?>
4. When building the dataset, anything I place in the "Query string" box has to be enclosed in <query></query> tags or it errors out. I am trying to understand how to translate the CAML viewer query (which does work but isn't wrapped in query tags) into something that fits between query tags, and it hasn't gone well so far.
<translation: To be at one with your reports Grasshopper, you must understand xml>
5. According to http://srv1/sites/ReportCenter/_vti_bin/lists.asmx, "GetListItems" operation is supported
<translation: you're getting warmer...>
6. According to the soap output of my site http://srv1/sites/ReportCenter/_vti_bin/lists.asmx?op=GetListItems, I am only allowed to specify the following parameters: listName, viewName, query, viewFields, rowLimit, queryOptions and webID.
<translation: that and $3.00 will get you a cup of coffee>
7. According to http://www.sharepointblogs.com/dwise/archive/2007/11/28/connecting-sql-reporting-services-to-a-sharepoint-list-redux.aspx, only listName, viewName and rowLimit parameters are usable(?) (query and queryOptions may not be working properly with SSRS).
<translation: that kind of sucks>
8. When this started mysteriously working again, I tested using the "/" at the end of the namespace (wouldn't work without) and the "=" sign in front of the parameter value as defined on the parameter tab of the dataset (turns out to be optional).
As long as I can query SharePoint and get my list information back, I'm going to consider this issue closed and move on to actually using this information in a report. I'm sure that won't work right either, but why stop now?!
6. Ok, now that I can read SharePoint list data with SSRS, I need to try and actually do something with it.
A. Begin by setting up new data to report on
1. Create a new custom list (myCustomList2) and add a test record. This list will simulate the data we intend to submit to SharePoint using InfoPath, so it has a number of custom/created columns in it
2. Modify the working information from #5 above; add a new shared data source (myCustomList2DataSource), tell the dataset to use the new shared data source, change the information set in the parameter tab (Name => listName, Value => =myCustomList2) and test the dataset. Lucky me, it actually returned the record I entered on the first try.
B. Begin to build the report with the dataset returned
1. So, as I'm feeling good that it's actually reading the list in Step A without me threatening to destroy the machine, I look to the left in the Dataset results navigation pane in VS2005 and realize there are NO fields for me to choose to report on.
2. At this point, I have no clue what to do about getting this XML data into a report. Not that I have a large clue about SSRS otherwise, but I have at least been able to build SSRS reports when using a SQL database as the datasource. Fyi, http://msdn2.microsoft.com/en-us/library/ms159741.aspx states: "Reports can use data from XML documents and Web services, or embed XML in the query. There is no built-in support for retrieving XML documents from a SQL Server database.", in case anyone is trying to do that....
RESOLVED. Since the fields were not appearing automatically, I had started to add new fields to the dataset manually (if it doesn't work, beat it with a hammer, right?). I entered half a dozen or so fields, each one with the exact name as displayed in the query results, and then decided it would be fun to hit the refresh fields icon. As soon as I did that, all the fields shown in the query immediately appeared in the dataset and I was able to add them to a report. I don't know if I hit the refresh fields when working in issue #5, so I can't say if they are there now because of that, or because of adding some fields manually first, a combination of the two, or if it's just one of those mystery items I'm reading about with sharepoint reporting.
7. Rows are being returned even though they have NULL values (so far anyway), and most data is returning nicely for the bulk of the columns I created in the list I'm reporting on. Here are the current issues:
A. I have one column in my SharePoint list that is multi-lined text. If the text type is either rich text or enhanced rich text, the value returned in the query is formatted like this: "<div class=ExternalClassyadayada<div>My notes display here". If I set the column to be plain text, this doesn't happen. I will need to figure out how to filter that for my report.
RESOLVED. David Wise had some code listed at http://www.sharepointblogs.com/dwise/archive/2007/11/28/connecting-sql-reporting-services-to-a-sharepoint-list-redux.aspx that addressed this issue somewhat. I modified it to match my circumstances. Disclaimer: I'm not a programmer, so use this at your own risk.
function ExtractMultiLineText(myField as string) as string
dim strBegin as string
dim strEnd as string
dim myBegin as integer
dim myEnd as integer
dim myTextLength as integer
strBegin = "<div>"
strEnd = "</div>"
if myField = nothing then return ""
if myField = "" then return ""
myBegin = Instr(myField, strBegin) + Len(strBegin)
myEnd = Instr(myField, strEnd)
myTextLength = myEnd - myBegin
if myBegin < 1 then return myField
return mid(myField, myBegin, myTextLength)
end function
B. I have two columns in the SharePoint list that are set as number values with 0 decimal places. When I query those however in SSRS, they return with the number plus like 12 zeroes behind the decimal. Not a major issue, but I'll put it on the list anyway.
RESOLVED. Used the Int() function; =Int(Fields!ows_myProblemNumber)
C. If I go to "/_vti_bin/lists.asmx?op=GetListItems", it appears from the sample soap output that I am allowed to ask GetListItems for is: listName, viewName, query, viewFields, rowLimit, queryOptions and webID. As I mentioned in issue #5, according to http://www.sharepointblogs.com/dwise/archive/2007/11/28/connecting-sql-reporting-services-to-a-sharepoint-list-redux.aspx, only listName, viewName and rowLimit parameters are usable(?) and query and queryOptions may not be working properly with SSRS.
So, if I can't put anything other than this in my query string;
<Query>
<Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems"/>
<SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction>
</Query>
and I only have a couple parameters to pass on top of that, then it appears to me that my options for filtering the amount of data returned from the SharePoint list is to figure out a way to do it with expressions in the parameters or in the report itself. Am I missing something? Is this really all I get to work with out-of-the-box?
More to come...

Server Software
SQL Server 2000 (all sps up to date)
SSRS 2000 (all sps up to date)
Scenario:
1 - SSRS + SQL2000 Database server
2 - Web servers
We have installed SSRS on 2 web servers that are acting as a web farm for a central Report Server.
After we installed SSRS on the 2 web servers the scheduled reports on the central Report Server stopped working.
We tried disabling the ReportServer service on the web servers and then the scheduled reports began to work again.
Why would the ReportServer service on the 2 web servers interfere with the central Report Server?
Can the web servers be used to load balance the scheduled reports?
Any advice would be appreciated.

Dear,
I have designed a SiteMap provider for SQL Server. But I am worried about the notification service of SQL Server. My SiteMap requires service broker enabled in SQL Server. When I have web farm (multiple clustered server) does the Sql Server service broker notify all the web servers? Or, it notifies only the server request?
Have anubody implement such scenario? Looking forward for your reply.
Sincere Regards,Sultan

I have implemented SQL cache dependency to invalidate cache whenever the result of the stored procedure gets changed. The stored procedure is written obeying all the notification rules.
Our problem:
As long as we are working on Local machine, Development server or Pre production server its working fine means the cache gets invalidated whenever there is any change in the result set. But the same implementation doesn’t work in Production. Cache does not get invalidated.
Difference in Production environment and other environment:
Production uses cluster SQL server, others use standard SQL server. Production has load balancing means application is deployed on 6 servers which hits same clustered SQL server. In application’s global.asax file i have Start dependency so I see 6 different notifications started in SQL server which is right. But whenever there is a change in result set the cache doesn’t get invalidated in any of the application.
My question is
Do we have to follow any different kind of implementation of SQL cache dependency for web farm and cluster SQL server scenario?
On the same note I would like to add, on the same SQL server I have one more database and a different application is accessing this database. This application is also using SQL cache dependency and its working fine. The only thing this .Net application is NOT deployed on web farm. Its deployed on single application server.

In our current project, we are attempting to use Broker for the middleware for a "queuing" solution that helps in throttling & load-balancing incoming messages. These messages could potentially be either long-running jobs or simply an incoming flood of messages received from our integration web services that are called upon via BizTalk.
For the posting of messages onto the "to do" queue, we are implementing the "fire & forget" pattern that has been discussed here previously and on Remus' blog. This aspect of the design seems to work fine for us. Currently we have this setup where activation is occuring on the target queue, but we don't want to hold open a thread there on the server while waiting for our synchronous calls to various web-services on the processing "farm" to complete.
The next evolution of our design is to try and move activation from off of the primary SQL cluster itself (i.e. activation is currently happening on the clustered SQL boxes) onto the individual processing nodes. For this model, we are looking at using SQL Express on each of the nodes as has been suggested here on the forums for other similar scenarios.
For resiliance to any node failures, we do not want to "route" the messages to the individual nodes hosting their own queues but rather have those nodes do a "read" from the primary queue and do the per-message processing and performing either a committed EndDialog of EndDialogWithError based on the success of processing each task/message.
To invoke the processing on each of the nodes, we need some form of mechanism to send a "wake up" and do the "reads" since no message is being sent to the node itself for any form of activation based on a queue that receives the actual "job". On the same hand, we are considering having a "wake up" queue on the nodes where a simple "wake up" message could be sent to all nodes/queues and then activation on those queues would then invoke the processing "loop" for each node.
My question is how to best establish this "wake up" call to each node. I think I've read about a queue that is internal to Broker itself that receives a message when new items are received in any queue. My initial thought is to put activation on that queue and have a procedure that sends the "wake up" to each of the nodes in our processing farm.
I am looking for any input where others have attempted to solve this type of problem with Broker.

Bradley A. Hehe

Hi
I am trying to create a scale-out deployment of Reporting Services
2005 on a NLB cluster web farm by following the instructions in:
http://technet.microsoft.com/en-us/library/ms159114.aspx
However, when I install and configure Reporting Services on the second
node, and then go back to the first node to join the second node to
the scale-out deployment (as described in step 11 under 'To install
and configure the second report server instance"), I get the following
exception:
ReportServicesConfigUI.WMIProvider.WMIProviderException: An unexpected
error has occurred. Details:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) ---
> System.Runtime.InteropServices.COMException (0x800706BA): The RPC

I have spent hours searching for ideas, but so far no success. I have
also tried the following:
1. Enabling DTC access
2. Ensuring RPC service is running on both web and db servers
3. Installing WMI Windows Installer Provider
4. Granting admin rights on both db and web servers to the account
under which Reporting Services is running
Any help or suggestions would be greatly appreciated. It looks like
this should be a straight-forward task.
Thank you.

We are using RS2005 for a year now and never had any problems especially with mail subscriptions.
Since we transferred from single RS machine to web farm everything works ok except mail subscriptions. Subscription sometimes (?!?!?!?!) refuse to export report to a document of any kind. I repeat that this is a random thing which is more often with PDF and less with Web Archive or Excel. We are using shared schedules and on demand execution of AddEvent stored procedure by night batches to send mail to users. Also, original error from RS log says something that this kind of operation is not supported for server working in native mode. We don't have SharePoint so we never used it in any other way then native mode and it worked.
Any idea will be appreciated!
Thanks in advance.
Update 26.06.2007
It seems that problem is not loading dll used to export report to a file but loading email subscription extension (dll that needs to be loaded for execution of email subscription.)
Original error from RS Log:

We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.

in the process of migrating a big db from server 1 to server 2, we had to roll back the change. I started with taking a full db backup and restoring it on server 2 with norecovery, and then a couple logs with norecovery, and then the last log with recovery.
Is there some way to continue this chain now, I mean to change the db to norecovery, or other way to restore logs.Â
I dont want to do a new full backup.
If I try to do a log restore now i get the message:
Msg 3117, Level 16, State 4, Line 1
The log or differential backup cannot be restored because no files are ready to rollforward.
Msg 3013, Level 16, State 1, Line 1
RESTORE LOG is terminating abnormally.

We have 3 replica AG setup. 2 replicas are in sync/automatic failover, the other(DR Server, different subnet) in asynchronous/manual mode…All these replicas were on sql server 2012, Recently we upgraded DR server to 2014. Since then we have a problem, the AG databases in 2014 instance went into ‘Synchronizing/ in recovery’ state…The SQL server error log has message, the recovery couldn’t start for the database ‘XYZ’…We tried to create a new database and add it to AG , it works for fine for other two 2012 replicas, but on 2014 we see the same issue

We have an issue with a 3 node SQL 2012 Always on availability group. Normal operation is node 1 (primary replica) with node 2 and node 3 as secondary replicas.After some patching, SQL wasn't running on node 1 hence the AG flipped over to node 2. This went unnoticed for some time and the transaction log for one of the AG databases became full on node 2 and node 3. (I think this is because it couldn't commit the transactions on node 1 so couldn't truncate it's t-log?) The DB is using synchronous replication btw.So I started SQL on node 1 and flipped the AG back to node 1 (with a data loss warning but I accepted this).Now the issue is that on node 2 and 3, the DB in question is stuck in a "Reverting / In Recovery" State. I've tried various commands such as ALTER DATABASE SET ONLINE, RESTORE DATABASE WITH RECOVERY etc but these fail stating unable to obtain a lock on the DB.
The weird thing is that on node 1 the state of the DB is "synchronised".how to resolve this issue on node 2 and 3? I've left them overnight (in case they were rolling back transactions, the DB is fairly large) but nothing seems to have happened. remove the DB from the AG in node 2 and 3 and add it back in again, ie recreate the replication?

Hi,
Here I will describe my problem.
1. We are loading large amount of data from database on background thread which is starting on Application_start event in global.aspx.cs file.The data is later cached for subsquent request to improve the performance.
2. Now when we put the application on web farm garden, it is not able to load the application.
3. We are sending the request the servers through Router kind of application.
4 This application is working fine on single server enviornment.
Please help us.

If you are doing a disaster recovery of an entire SQL 2005 cluster, can you just install SQL server and restore the system database to get the configuration?

Hi all, we have a SQL 2000 database which is for recording job information. we are trying to do a sharepoint page that will show all outstanding jobs with conditionl formating to hilight overdue jobs red. we have managed to do this by date with no problem but we are unable to do this by time.
We have created a view that sharepoint looks at for the needed fields. the job due time field only has the time entered in which means the default date of 01/01/1900 gets entered by the system.
we need away that the only the time is outputted in the sharepoint view and a way to apply conditional formatting to this field in sharepoint and a way to compare the this time to the current system time.
I hope this makes sense, as we are complete novices when it comes to SQL. Please ask if you need any more information.
Any help or a point in the right direction would be deeply appriciated.
