Can You Mirror To Multiple Instances On Same Server Via One Endpoint?
Oct 29, 2007
Hi all,
Can a MIRROR server have mirrored databases on many instances or must all of the mirrored databases on a server reside on one instance?
This initial implementation worked fine:
PRINCIPAL ServerPROD1instance01 endpoint1430
MIRROR ServerDRinstance01 endpoint1440
WITNESS ServerZ endpoint1450
This second implementation (different PRINCIPAL server to same MIRROR but to a different instance)
PRINCIPAL ServerPROD2instance5 endpoint1430
MIRROR ServerDRinstance02 endpoint1440 <<same mirror server but different instance
WITNESS ServerZ endpoint1450
I know that you can only install one endpoint on each server. Does that mean that the endpoint can only resolve to one instance though?
The second implementation looks fine until the final step (start mirroring). I get the following error:
An error occured while starting mirroring
Alter failed for database 'test'
An exception occurred while executing transaction-sql statement or batch
The remote copy of database 'test' does not exist. Check the database name and resissue the command
I have created the test database in instance02 and rolled a log onto it. It is currently in recovery mode - waiting patiently for another log.....
I have read books online and 2k5 unleashed but can't see anything that relates to an implementation across mutliple instances on the DRmirrored servers.
Has anyone tried to do this? Can you confirm its possible?
I was told that if I wanted to setup mirroring between multiple instance on the same server that each endpoint had to be different number. Is that true? Or can I use the default 5022 for each instance?
I have created a Endpoint with "Mirroring Server" on the mirroring instance. Due to the keyword server i am not able to drop the endpoint now.
Also am not able to configure a mirror in a windows workgroup also( the two systems principal and mirror are under same network ). I have followed many ways as per msdn articles and other blogs.
I am not able to connect to the mirror server.
I have tried giving the ip addr and the port no, also the computer name:port no, computername.local:port no etc. Both the systems are running on sql server 2008 only
I always get the error as Connection cannot be established to the destination.
(I have also enabled the ports in firewall by creating inbound and outbound rules)
The issue probably lies in NAMING server address i guess.
In documentation about SQL mirroring, the only thing about version requirement are that: 1) enterprise, standard, developer edition; 2) SP1 for official support
Is there any requirement for the Principal and Mirror SQL instances? For example, can one be Enterprise, the other one be Standard? Can one be SP1 and the other one be SP2?
It seems we are having some problem with the above scenario, not sure if that's supported..
I think this is a question for the specialists among us.
Can I use one general reporting server (installed on instance MAINREPORTING) for multiple customers who all have their own sql instance (CUST1, CUST2, CUST3, ..) I would use UserAuthenciation on the reportserver url to display the specific reports customers can use.
Is this possible, and what do i have to take care off concerning installation and/or configuration (especially on the reporting side) ?
I am running SQL 7.0 as the default instance and SQL 2K as a named instance. Each is using a different port....7.0 is using port 1433 and 2K is using 1024. Everything appears to be up and running fine on the server. However, I am not able to access the 2K instance from a client. I have tried to use both TCP IP and named pipes setting them up using the server network utility and the client network utility. No luck anywhere. I continue to get connection errors...check network documentation...
Is there any limit on SQL server Multiple Instances? if we require to run 60+ Instances on single machine what will be the minimum hardware requirements.
I am using SQl Server 2012 Database Mirroring with around 40 gb as mdf and 1 gb as ldf. Now my ldf size increased . How to reduce ldf size while mirror enabled with mirror server and witness server. Can shrink the ldf with mirror enables.
1.) Is it possible to install Analysis Services on multiple SQL Server 2000 instances? If it is, then can you instruct me as to how to perform the install. If it is not possible, then does one restrict access to cube data via the Database Role Manager?
ie. The host box is - DOILAB30 with Analysis Services & SP2 Instance - DOILAB30/DOILAB30_FIN (Can AS be installed here?)
Do I severely restrict the membership of OLAP Admins?
2). Re. AS maintenance. - How do I backup and restore OLAP dbs/cubes etc. Following a restore, what issues, such as cube users/permissions should I be aware of? (if any).
There are several instances in SQL Server. I use RDA method to access SQL Server from mobile devices. But RDA method only gets the server IP,not the instance name. So, how can I define RDA to access to the instance that I need?
I am trying to built a general demo machine for our multiple resellers.
Is it possible to have multiple database instances (one per reseller) with each of them their own reporting instance, running on the same server (also same IIS). In our DNS and in the IIS settings i will reroute the specific reseller to his specific reporting url (eg: http://www.demosite.reseller1.com/reports (this is not a real url), will be rerouted via dns to the specific reporting url for reseller one ... and so on.)
Each reseller must be able to has it own reports, subscriptions, models and access to reportbuilder.
Can this be accomplished ?
I have tried already a few times but get stuck when i want to upload reports/datasources to the specific websites. Also i have encountered the fact that if i succeed in uploading data to one reporting site and i want to upload different data to another site, the initial site is also changed with the data of the second upload.
Can anyone point me into the right direction how to solve this problem .
Is it possible to have more than one instance of SQL Server on a failover Active/Passive cluster? What are the concerns/ramifications if that indeed is possible?
Greetings... I'm working at consolidating several Reporting Services installations into one so we can decommission some old servers. We have two Report Servers that are in SQL Server 2000 and three that are in SQL Server 2005 (none are in a web farm configuration). I can upgrade the 2000 databases to 2005 format just fine, but now how do I merge these five ReportServer/ReportServerTempDB databases into one? I'm reluctant to redeploy reports to the "official" Report Server because we lose security, subscription, and scheduling information by doing that. So redeploy would cost us time and data loss over hundreds of reports, thus my hope to merge the databases at a data level. Is there a tool to automate this process, or has anyone tried this before? Thanks in advance.
Hi,I'm having a problem running a distributed transaction between twolinked servers that both have multiple instances of SQL Serverinstalled on them. This is the error message that I receive:"The operation could not be performed because the OLE DB provider'SQLOLEDB' was unable to begin a distributed transaction.[OLE/DB provider returned message: New transaction cannot enlist in thespecified transaction coordinator. ]OLE DB error trace [OLE/DB Provider 'SQLOLEDB'ITransactionJoin::JoinTransaction returned 0x8004d00a]."The query follows the format:"BEGIN DISTRIBUTED TRANUPDATE [LINKEDSERVER1INSTANCE_NAME].DB.OWNER.TABLENAMESET fieldname = alias2.fieldnameFROM tablename alias2JOIN [LINKEDSERVER1INSTANCE_NAME].DB.OWNER.TABLENAME alias1on alias2.urn=alias1,urn"[color=blue]>From what I can gather from various sources the SQL Server must be[/color]named the same as the computer which it is installed on. However, if Ihave two instances of SQL Server, they cannot both be named the same asthe computer. Does anyone know of a way around this or whether I'mbarking up the wrong tree completely?Many thanks.
I have a website running under Windows Server 2003 which I am trying to deploy Reportin Services to using a custom security extension using Forms authentication. There is also another website which is just a Report Server running on this IIS 6.
On my development machine, XP with IIS 5.1, the Website with Reporting Services using forms authentication works fine, shares cookies for authentication and all that jazz. but trying to configure a second instance of Reporting Services on Server 2003 is not behaving.
Is there some trickery or details involved with running two instances of Reporting Services?
Also in the Configure Report Server tool it is failing and so not initializing on the last step of the Database Setup
Setting Connection Info for Reporting Server
ReportServicesConfigUI.WMIProvider.WMIProviderException: An error occurred when attempting to connect to the report server remote procedure call (RPC) end point. Verify that the Report Server Windows service is running, and then retry the operation.

We are trying to setup a number of SQL Server 2005 database instances on a single server. The server has multiple IP addresses bound to its network interface (card). Each instance is configured to listen on a specific (unique) port on 127.0.0.1 and port 1433 on a specific (unique) IP address configured on the network interface. Finally, there is another instance of SQL Server (which also has the Reporting Services, Analysis Services and Integration Services installed) that does not allow remote connections and has TCP/IP disabled.
SSL is configured for all instances, apart from the non-remote connections instance, as follows: The same self-signed certificate is specified for every instance. This certificate has been configured for all 127.0.0.1 ports and port 1433 on all IPs in use for any of the instances using httpcfg as documented. The Force Encryption option is enabled and the Hide Instance option is disabled.
All appears to work correctly, and the "The certificate was successfully loaded for encryption" message appears when sp_readerrorlog is run, for the instances it is supposed to. However, at some point a problem occurs. The Force Encryption and Hide Instance labels _disappear_ (leaving blank spaces in the grid) from the interface, with the drop-down settings still visible. This seems to happen after installing an additional instance, although on one occasion it was after the 3rd was installed and on another occasion the 4th. Uninstalling the instances (even all of them) does not seem to help - only removing SQL Server 2005 completely and re-installing allowed the labels to re-appear.
Another concern is that after problem occurs, it appears that the settings are not being interpreted correctly. Even if the certificate is disabled for an instance, the message "The certificate was successfully loaded for encryption" appears, instead of the instance using a self-signed certificate. Additionally, on some occasions, the values for the Force Encryption and Hide Instance are swapped (or at least the values in the positions that used to be inline with the labels for these options).
As an additional note, various IIS Web Sites are configured on each of the IPs on the network interface. These are also using the same self-signed certification for SSL and are all using port 443, which none of the SQL server instances are configured to use.
Any feedback or suggestions on this would be appreciated. Thanks.
I am currently having publisher(database A), subscriber (database B) and distributor on the same instance for a test environment that is using a uni directional transactional replication. Now I need to setup another unidirectional transactional replication in the same test instance but for a different database. Publisher database is D and subcsirber database is E.
I have a situation where I would like to set up one DB server instance for US and anther one for AUStralia. The Instance should share the same data base/hardsisk. One of the instances will be running in using US time zone and anothe one in Australia time zone. There will be 2 Application instaces one poinint to each SQL Server instance. This applications does write into the database
So the underlying requirment is to have 2 database server running in differnet time zones but accessing the same disk/set of data What is the best way to do this? Is it linked servers?Girish
Hi, I am trying to install multiple application services on 1 sql server database. Is this possible? I do not know how to install anything but the default application services settings for the membership, roles, etc.
I'm looking at installing 2008R2 and 2014 side by side, then using Mirroring to provide HA for the 2008R2 instance and AoHA for the 2014 instance. I'd be using the same two physical servers for both the Mirroring pair and the AoHA pair.
My client has a server running MS 2003 Server for Smal Business Server, and it has SQL Server Express 2005 installed (I believe it is installed 3 times, as part of SharePoint, Veritas Backup Exec and ACT! applications).
I am trying to implement an application that uses SQL Server 2000, but the Server 2003 SBS does not support that version. So I need to launch an additional instance of SQL Server Exp 2005.
To do so, do I need to download and install SQL Server Express 2005 software again? Or can I just run SQLSVR.exe from an existing instance, but with a different instance name (sqlservr.exe -s<InstanceName>?
The reason I need another instance is that these existing instances limit DDL statements.
I am new to this and compare it to launching MS Word multiple times - you don't need to reinstall Word to run it multiple times.
Is launching from the command line a bad idea - and if it is, what is the better way to ensure that it launches under the local system context a service?
Thanks in advance for any help and insights. It is much appreciated.
I am playing around in a test environment with SQL Server 2014. I have a question about the default location of the report server databases when you have multiple report server instances installed on one server.
I did a very simple install of SQL Server 2014 with the database and Reporting Services in Native Mode (install only) features selected. Accepting the default locations, I ended up with the following locations as you would expect:
Running the Reporting Services Configuration Manager, I created the Report Server database. After creating the Report Server database, the related files will be located below in the SQL folder as I would expect.
Next I installed another instance, which I called Test, of SQL Server 2014 like I did above. I now have the following folder structure the Test instance as I expect.
Each webmethod will be accessed thru a multiview on the page.
It would seem to me that I can describe the webmethods using a fully qualified stored proc name and that wouldn't cause a big problem. But, my question is what does that DATABASE=N'fadb' clause do?
Does anybody see a problem with using a single endpoint to access multiple databases?
Any advice would be greatly appreciated as this is my first web app using this data access method.
One of my varchar columns in a table has multiple key words enclosed in a pattern of special characters.
Eg: William Shakespeare was an English [##poet##], [##playwright##], and [##actor##], widely regarded as the greatest [##writer##] in the English language and the world's pre-eminent [##dramatist##]. He is often called England's national [##poet##] and the "Bard of Avon". His extant works, including some collaborations, consist of about 38 plays, 154 [##sonnets##], two long narrative [##poems##], and a few other [##verses##], of which the authorship of some is uncertain. His plays have been translated into every major living language and are performed more often than those of any other [##playwright##].
I need to write to query to find all distinct key words that are enclosed within [## and ##]. My query should yield the following results from the string in the example above
[##actor##] [##dramatist##] [##playwright##] -- 2 occurrances, but I need it only once in my result set [##poems##] [##poet##] -- 2 occurrances, but I need it only once in my result set [##sonnets##] [##verses##] [##writer##]
I need to run this on a large table, so I am looking for the best possible way to minimize any performance issues.
Just give you sample code, I have provided below 2 separate snippets, one with table variable and another with temp table.
DECLARE @MyTable TABLE (MyString VARCHAR (8000)) INSERT @MyTable VALUES ('William Shakespeare was an English [##poet##], [##playwright##], and [##actor##], widely regarded as the greatest [##writer##] in the English language and the world''s pre-eminent [##dramatist##]. He is often called England''s national [##poet##] and the "Bard of Avon". His extant works, including some collaborations, consist of about 38 plays, 154 [##sonnets##], two long narrative [##poems##], and a few other [##verses##], of which the authorship of some is uncertain.
When I am in Visual Studio 2005, and I try to add an SQL database, I get the following error "generating user instances in sql server is disabled. use sp_configure user instances enabled to generate user instances." I am currently using SQL server 2005 Express. What do I need to do, to create an SQL database? Thanks in advance.
After adding the Witness Server to the Mirror session, the Witness Connection state between the Mirror and Witness Connection is Disconnected and the state between Principal and Witness Connection is Connected.
The procedures defined in Books Online was used to setup Database Mirroring...when the Witness server was added to the Mirror session, only the alter database T-SQL statement was executed on the Principal server.
ALTER DATABASE <db_name> SET WITNESS = 'TCP://<servername>:<port>'
After executing the above statement, a few seconds later the state between Principal and Witness Connection changed to Connected and the state between Mirror and Witness Connection remains Disconnected.
The Mirror session is not using Certificates, every server is on the same domain, using the same domain login account, and all servers have SP2 installed running Enterprise Edition.
Any idea's why the state between Mirror and Witness Connection remains Disconnected?
I had a server with SQL Server 7.0 I installed a named instance of SQL Server 2000 and then i passed all my DB of the 7.0 instance to the 2000 instance. Then i removed the 7.0 instance, that was the default instance. So at the moment there is only the 2000 version, but it isn't the default instance Can the 2000 instance become the default instance? (So that clients can connect to it simply through computer name, and not creating an alias)
I would like to know if it is possible to have different applications on separate report servers sharing one report server database. If so are there possible issues or ptfalls to this type of architecture?
i have sql server 2005 express running. during install, i had issues with a system dll that i found answers online and resolved. i am still very green, but i know much more now than i did at the time. i believe that as a result of the partial then failed installs i have multiple instances either fully or partially installed. when i am in the sql server mgmt express environment, it lists two sql engines. i only ever use one, and would like to safely remove the second without damaging or corrupting anything done with the other instance. my reasons for wanting to do this are twofold. first, i would like to free up the drive space taken up by the second instance. (i am a stickler for clean harddrive mgmt and maintenance). second, now that i have used the software and am somewhat more familiar with it, i would consider installing a second, intentional instance so that i may attempt to better customize some of the install-time settings and configurations. can anybody give me any pointers/ guide me in the direction of information on how to SAFELY go about this? thank you in advance for any help.
I created a second SQL2000 instance on a Windows 2000 server. The strange thing is that I can create an ODBC connection to the default instance but cannot for the new named instance. If I try from a client that has SQL installed on it, I can see both instances. Any idea why this is happening?
We're trying to decide if we should use a single large instance of SQL Server or multiple instances on the same server. This is for a dev environment.Have to limit max RAM per instance so no instance grabs it all.There will be I/O contention and CPU contention between instances since the different instances won't coordinate with each other.It limits the available RAM for In-Memory tables..It sets lower limits to the amount of RAM available for any given query, causing artificial "contention" even when there's nothing else running at the time.
According to the Task Manager, on my SBS 2003 Server, I'm running multiple instances of SQL. How do I determine which instance(s) are required to maintain server stability, and which are not. My Server resource use continues to be a perennial problem. Please advise.
