Sql Server CE 2.0 Proxy Replication Scenario
Jul 14, 2006Dear all,
Since Windows Integrated Authentication does not work over proxy for Replication, could I still use SSL or SQL authentication over proxy? Thanks for any advice.

Replication Scenario
Dec 17, 2006Hi all,
I have a huge replication task I need to perform. The source table has over 250,000,000 records and everyday approximately 400,000 records are added to the system regularly.
Currently, I am running snapshot replication and it's taking 10 to 11 hours to complete (The internet connection between the production and the report server is slow). The reason I am using this method is because the source table does not have a timestamp column (so I can run an incremental replication) and I cannot modify that table because it belongs to a third party software. It does have a field which is linked to another table holding the timestamp.
Here is the source table and the other table's structure for reference:
DataLog
Name Datatype Size
DataLogStampID int 4
Value float 8
QuantityID smallint 2
DataLogStamp
ID (Which is foreign key to DataLogStampID field in the above table) int 4
SourceID smallint 2
TimestampSoruceLT datatime 8
What I would like to know is, what is the best practice to handle such replication with MSSQL Server 2000.
I am thinking of developing a procedure which follows the following step using a temp table:
This procedure will run (say) every night.
The temp table will contain a timestamp field.
For one time only, I will run a snapshot replication, so that I can have the existing data into the destination db.
I will record this timestamp into a repl_status table which holds the timestamp of the last replication.
The procedure will read the record from repl_status and select all records from the source table which were added since this date and put them into a new temp table (this table will have the same structure as the source and destination tables) and then a snapshot replication will "add" these new records only every night to the dest. table. By using this method, I will only transfer the records which have been added since the last replication (last night - less records).
Any comments would be greatly appreciated.
Thanks for your time in advance,

Jul 23, 2005I have a product that sits on a main server and wish to implementfunctionality to allow salesmen to come along, pick up a snapshot of thedatabase, go away and maybe modify/add to it and then come back and"synchronise" their data. I'm reading up on Merge Replication for thispurpose. But anyway, I created a publisher on my server and it went awayand generated a "rowguid" column on all of my tables (my tables all have anIdentity column key field). Now of course my "Inserts" no longer work, asthey expect a GUID. I would have expected SQL Server to automaticallygenerate a guid for new inserts (in a similar way to it's TIMESTAMP), but itappears it doesn't, despite the fact I have "(newid())" as the default forthe column. It always inserts the same value:{00000000-0000-0000-0000-000000000000}.So, back to basics, now I have a guid field for each record, how do I manageinserts?Thanks.

Jul 2, 2007I have two sites. Site A and Site B
Each site has two databases
Site A
Db1
Db2
Site B
Db1
Db2
Site A Db1 has to perform transaction replication to Site A- Db2 and Site B- Db1 and Db2.
I started Site A as pubisher and distributor and Site A and Site B both as subscriber.
Site B is in a different geographical area (state).
----------
Please suggest the best scenario to save bandwidth and server load for Publisher, and Distributor.
-------
Earlier I thought that I will implement local replication between Site B - in between Db1 and Db2. The Sql Server does not let me set Db1 as publisher, and distributor for its local database Db2.

P.S. My all databases need same transactions though they are connected to different hardware at different places. So please don't question that why I need four similar databases.
Merge Replication Weird Scenario?
Dec 15, 2005
On the national Server: SQL 2005 Enterprise
On the mobile clients: SQL 2005 Workgroup.
I was asked to find a solution to such scenario
2 mobile subscriber S1 and S2 to the same simple merge publication P1 on server N
Day 1,
S1 and S2 both synch up with N and both go off to do fieldwork
Day3,
S1 and S2 both synch up with N.
S1 goes back to work
S2 shutdown the laptop and goes on 2-week vacation.
2 Weeks late
S1 Synch up wit the server and goes off to do fieldwork.
S2 meets S1 in the field. Their workfield is in the North Pole.
S2 has the laptop with data 2-weeks old but no longer can have access to the master publisher N to synch the replica and get latest changes.
S2 will have to sync with S1 since S1 database is fresh. The challenge is to have S2 and S1 replica identical
The Questions:
Is it possible for S2 to sync with S1?
if yes, How to go about it€¦ we need S1 and S2 to have identical replica on their machines?
Now that S1 and S2 are have identical databases and are both doing their fieldwork in the northpole. Can they both sync back with the national publisher N when they have access?
Keep in mind that S2 got its data updated from the replica on S1?
Thank you!

Merge Replication Using Web Sync - Proxy Auto Config Problem
Aug 16, 2006Hi
I am trying to setup merge replication using web sync. I keep on getting the message: The Proxy Auto-configuration URL was not found. Yes I have read all the postings telling me to check my internet explorer settings concerning proxy server and auto-detection - I am not using a proxy - auto detection is unchecked.
Does anyone have another clue?
Thanks

Proxy Auto-Configuration Url Not Found Error - But Not Using Proxy
May 15, 2007I have read all the posts regarding this error, but non-solve my problem as I had already addressed them.
I am setting up Merge Replication via the Web and I get this error when i try to sync. Let me give you some background.
I wrote a small windows test app to test merge replication, in which i am using RMO to accomplish the replication. This works. It syncs every time. I then copied the "sync" code from the winform application and created a Windows Service in which i placed "sync" code. The sync code did not change other than adding the additional following four lines:
_mergeAgent.InternetUrl = _internetURL;
_mergeAgent.InternetLogin = _internetLogin;
_mergeAgent.InternetPassword = _internetPassword;
_mergeAgent.InternetTimeout = _internetTimout;
where the internet url is https://ipaddress/virtualdirectory/replisapi.dll
I have been working with this for a while now trying to figure out why this works (on the same machine) in a winforms app but not through the web (via a windows service).
Any insight would be greatly appreciated.

SQL Server Express Scenario
Jan 10, 2008Hello !
Please, I am new on SQL Server,
1.It's possible following scenario ?
I want to implement an application with SQL Server Express installed on a PS as server. Other PCs - from network or from http network - could connect to this sse database (my intention is to open a port on the server for using the internet network).
If yes, please give me an example of adequate string connection to use in application.
If no, what amount from this scenario could be implemented ? (And also, if you can, an sample of connection string).
2. Do you know what are the limitations of using SQL Server Developer Edition (~50$ price) in this scenario ?
Thank you very much !

Would This Scenario Benefit From SQL Server 2005 64bit?
Oct 2, 2007We have an application where part of the database is used for searching products and is very processor intensive due to the number of permutations and calculation that are required. This section of the database is scaled out by using transactional replication so that the €œsearch€? load is removed from central database€™s daily operations.
Each €œsearch€? server can handle around 15,000 search an hour with SQL taking about 3 seconds to return the result in XML (the system has be optimised to squeeze out every last bit of performance). This is in a 32bit environment. One other point, which is probably relevant, is that the Search data only totals 500MB.
With the possibility of upgrading these severs in the near future would we see any performance benefits in going 64bit. I know we won€™t take advantage of increased memory access due to the size of the search data but is there any discernable performance advantage between 32bit v€™s 64 bit processors and SQL Server 2005 64Bit. Or should I stick with SQL Workgroups and 32bit processor and save on the Standard SQL licence?
Many thanks

View 1 Replies View RelatedVB App Connect THROUGH Proxy To A Remote SQL Server
Feb 13, 2008I have a VB.net app that connects to a remote SQL server via TCP/IP. Most folks can connect just fine. However some enterprise users are in a corporate environment that will only allow connections through a corporate proxy server.
The VB app does the connect to the remote SQL server via a fully routeable IP address over port 1433, implemented via a series of table adapters.
Having no such experience, I have no idea what I need to do to my app to allow it to connect THROUGH a proxy. And what sort of interaction I will personally need to have (if any) with thier IT department to configure the proxy server in any way. The user mentioned that "Only permissible outbound connection is through proxy server and it is only allowed with TCP/IP port 80 and it is only possible by authenticating with Domain ID and password." I would assume that means the connection from the VB app to the Proxy server is over port 80 and that somehow the proxy server will know (or be told) to then route to IP address of the SQL Server over port 1433.
I realize that one possible solution would be to create a WebService that runs on the same machine as the remote SQL server and have the app connect to that. However that will require a lot of rework on the application. We are looking into doing that, but right now I need a short term fix that does not require such a major rework.
Can anyone offer any insight or links that might point me in the right
direction?
Thanks!

A Newly Placed ISA Server (2006) Is Not Allowing My IP Phones Register To A Remote Proxy Server Outside My Network
Apr 22, 2008
Hi all,
I am having seriuos problems getting VoIP traffic into and out of my network via the ISA server which we just newly installed.
My network topology is such that the phones i am using for the VoIP service, sitting inside my network and behind the ISA server, have to register to some remote proxy server outside my network and as soon as it registers i can begin using the service. The VoIP service is on the platform of SIP and uses udp ports 5060 and 8080.
I have permitted the necessary ports on the ISA server for the service being UDP port 5060 and 8080 but still cannot get my VoIp traffic through the server.
Please i need some help here as regards something i am supposed to do or something i am not doing right on the ISA server to permit my traffic.
I am a newbie to this Microsoft ISA server and i hope you all understand
Thanks in anticipation to your replies.

Report Builder Behind The Proxy Server Issue
Mar 13, 2008We implemented Custom authentication with reporting services, everything works fine. At our client's site from one of there computer we did the following :
1- open internet explorer and access http://myserver.com/reportserver/reportbuilder/reportbuilder.application
2- the Report Builder Click once application was successfully downloaded onto the clients computer.
3- client was prompted to enter username and password. Client was able to see the report model and create,save reports to the reportserver.
4- close the report builder and try to access report via http://myserver.com/reportserver/reportbuilder/reportbuilder.application, this time the report builder launches but there is no prompt for username and password, instead it's asking to select a reportserver.
5 - tried selecting http://myserver.com/reportserver, there is not popup to enter username and password and we get the error message "unable to connect to server at http://myserver.com/reportserver , enter a different URL and Try again.
.NET framework 2.0 is installed on the client's machine. Our client can access http://myserver.com/reportserver/ from internet explorer.
Our client machine is behind a proxy server . Could this be caused by the proxy server. Why is report builder not prompting for credentials when launched. It only prompts for credentials the first time (installation). Any idea or anyone encountered this issue. we need a fix, because our client cannot access the report builder...

Execute A Stored Procedure Which Calls SSIS Packages Using A Proxy Account For Non Sysadmins In Sql Server 2005
Sep 18, 2007
Hi all,
I have a problem while i create a proxy account.The situation is like this...There is a user who has an login in to the server.He has a stored procedure which calls some on the SSIS packages and XP_cmdshell...so this stored procedure basically load some data in to the tables .So for the login in order to execute the stored procedure as he is not a Sys admin I have created a proxy account in my account as Iam an SA and then in the proxies and in principals I selected his login name and this way I have created a credential and a proxy account.
Now the problem is if he logins with his id and password and try to execute the stored procedure it gives an error message
Server: Msg 15153, Level 16, State 1, Procedure xp_cmdshell, Line 1
The xp_cmdshell proxy account information cannot be retrieved or is invalid. Verify that the '##xp_cmdshell_proxy_account##' credential exists and contains valid information.
....so this mean the login is not able to see the proxy account.So what I did is I created a job and then in the job owner tab I have selected his login and then created a step with the type operating system (CmdExec) as I need to just execute the stored procedure and used the proxy account that I have created.
so I gave the command -- exec <stored procedure> --.
But this job fails and gives the error message as
[298] SQLServer Error: 536, Invalid length parameter passed to the SUBSTRING function. [SQLSTATE 42000]....
So now ....first My question is am I doing in a right way....if its right then why Iam not able to execute the stored procedure.
If there is any other way through which I can execute the stored procedure using a proxy account for the logins who are not sys admins....please do let me know.....
Thanks

Scenario
Apr 23, 2004Consider the following scenario:
I got 2 webservers (2003) using NLB.
I want some kind of common data store (SQL Server).
I need this data store to be fault tolerant.
I don't have any more machines.
I don't have an enterprise licence for windows.
How do I solve this???
Is This Scenario Possible?
May 4, 2007I have a company with 5 offices connected with a dedicated line (500+ employees).
They have five databases, one in each office.
Now they want a new application which will replace the old (VB6 on MySQL will now be VB.NET 2.0 with MS SQL Server 2005).
The want all the data availiable in all the offices. We will still have 5 databases in 5 offices, but all with the same data.
Sometimes the dedicated line is lost.
Now I have a few questions:
Will the database be still running while a line is down?
Will the database be still running if replication is of type Merge (instead of continuesly).
Is it good practice to use unique identifiers versus Numeric keys?
Is it good practice when the application uses the "master" database to save global things like "Suppliers" and the local database to add and change Orders?
Do you have some recommended reads?
Thx for your time!

DR Scenario
Aug 13, 2007For High Protection mode (2servers, no witness, FULL safety), in the event of a catastrophic failure of the principal, can a remote (but well connected) mirror be forced to assume the principal role? The MS manual "Database Mirroring in SQL Server 2005" on p2 says the failover type for HP mode is manual only (as opposed to forced). Elsewhere it seems to seems suggest otherwise but there is no clear and unambiguous discussion describing the exact procedure.
Can anyone clarify this matter? Thanks,

SSB Scenario, Can It Be Done?
Oct 29, 2006I currently have a workflow "like" application which uses msmq to pass messages to each step transactionally. I'd like to take advantage to something like SSB to make the app scale. Here's how it works today:
Start Workflow WebService puts message on queue.
Windows Service has threaded listeners on each queue for the workflow.
The listeners do a transactional Receive off the queue. By doing this is in a transaction, we can enforce that only one listener will pick up and process the message. Once they have a message they call a .Net Assembly to perform some work. Once the work is performed succesfully, the listeners put the work context on the next queue using the same transaction as the receive and commit the transaction effectively removing the message from the receive queue permanently. If a fatal error occured during processing, the work context is moved to an error queue transactionaly. If the process blew up due to other reasons, the transaction is rolled back and the message reappears on the original queue so that another instance of the service can pick it up. Currently all this is running on one instance of the Windows service and cannot span more than one host machine since MSMQ did not support transactional reads off public queues without using DTC.
I saw the external activator sample and it looks great but I have a few questions. First, I'd have to modify it to call assemblies instead of external processes. No biggie there. One other requirement that one and only one receiver should process the message and that when the next message is sent to the next queue, it's done within the same transaction as the receive. I hope that this can be done without any deadlocks. I also saw mentioned somewhere that this messaging could advantage of the local SQLExpress instances so that even if the main SQL Server instance is down, the messages can go out. Last requirement is that our message is a blob (serialized .Net object) so how do we define that kind of message?
Thanks

My Synchronization Scenario
Sep 22, 2005Hi, I want to know the a solution for my Synchronization Scenario
I have a several client databses which are SQL Server 2005 Express and i have a master database which is SQL Server 2000 containing all the individual Client databases. All the individual client databases are kept seperately at the master location. I need to Synchronization the client database with its copy at the master database (something like Merge replication). Both the Client Copy as well as Master Copy could be Publishers & Subscribers.
Now the problem is Because of security & firewall issues, only the Client should have the ability to schedule & initiate the synchronization process with the master copy. Unfortunately SQL Server 2005 Express has only subscriber agent and not a publisher agent.
Any help on how to achieve this would be appreciated . Thank You
Best Practice For This SP Scenario !
Oct 10, 2005Hello All ..
This is the scenario I'm having :
-- I'm a beginner so bear the way I'm putting it ... sorry !
* I have a database with tables
- company: CompanyID, CompanyName
- Person: PersonID, PersonName, CompanyID (fk)
- Supplier: SupplierID, SupplierCode, SupplierName, CompanyID (fk)
In the Stored Procedures associated (insertCompany, insertPerson, insertSupplier), I want to check the existance of SupplierID .. which should be the 'Output' ...
There could be different ways to do it like:
1) - In the supplier stored procedure I can read the ID (SELECT) and :
if it exists (I save the existing SupplierID - to 'return' it at the end).
if it doesn't (I insert the Company, the Person and save the new SupplierID - to 'return' it at the end)
------------------------------------
2) - Other way is by doing multiple stored procedures,
. one SP that checks,
. another SP that do inserts
. and a main SP that calls the check SP and gets the values and base the results according to conditions (if - else)
3) it could be done (maybe) using Functions in SQL SERVER...
There should be some reasons why I need to go for one of the methods or another method !
I want to know the best practice for this scenario in terms of performance and other issues - consider a similar big scenario ..... !!!
I'll appreciate your help ...
Thanks in Advance . ! .
CASE Scenario
May 26, 2008How can I be able to use "NewReceivedTime" as a variable?
Since having to create a new column using CASE statement in SQL would mean that user will not be able to use this new column name and having to receive error such as "Invalid Column Name: NewReceivedTime "
(case
when <value>
else <value>
end) as NewReceivedTime
I'm asking this because, I would want to use "NewReceivedTime" I've created to equate to another Time Column like
NewReceivedTime = LogDateTime something like that.

SQL Express Scenario.. Is This Possible?
May 16, 2007What I'd like to do is use SQL Express as a back-end for an existing Access 2003 application. The application is currently a single-file Access solution. I'm just investigating options to separate the front-end from the back-end so that the users can access a single data store from multiple PCs. We're only talking about maybe 5 users total, and really no more than 2 accessing it simultaneously at any given time (although the same setup exists in several offices). Right now they are just opening the Access db from a fileshare. This has resulted in corruption on a few occasions, which is part of the reason for wanting to replace the current solution with something that will be a little more robust. I'm wondering if there is a way to deploy a SQL Express db on a fileshare so that it can be connected to by the Access front-end. While we can install things on their desktops, we can't install anything on the file server, we can just put files there. Is there any way that I could make that solution work, or should I just stick with separating the Access front-end and back-end?
Thanks,
Kris

Help With This Scenario On DB Mirroring
Dec 24, 2007Hi,
I'm about to implement a DB Mirroring on my production server.and i'm wondering about the scenario what will happen if.
1. if my primary server suddenly die.how i can operate the mirror DB without losing data?
2. when the primary server comes to life, how i make the primary server to lead again with the DB Mirroring?(do i need to recreate all procedures of DB Mirroring again)
3. how can i be sure that the DB mirroring is indeed mirrored on the drp server?
4. what about alerting - can i be notified via email if the DB Mirroring isn't sync? or if the drp server is down and other issues that can be occur .
Thx
