[THIN] Re: Migrate SQL Datastore to another SQL Server

Angela,

 

The dsn file can be very simple :

 

[ODBC]

DRIVER=SQL Server

UID=(user)

DATABASE=(database)

APP=Citrix IMA

SERVER=(SQL instance)

 

will work - so the dsn file can be the same for each server

 

What you can do is copy a script to each server that copies the dsn from a central location, executes the dsmaint command and restarts the IMA service; optionally you can get it to dump the reg key and compare

 

I’d start with your test servers, and once you’re happy go on to the farm starting at the zdcs... in the past I’ve used psexec with a file containing the servers to change to run the script.

 

For the summary database connection server –

 

1.       Sleep  the summary service

2.       Backup/restore the summary database

3.       Test connection to the new database

4.       Reconfigure the odbc connection on the connection server & test it

5.       Wake the summary service

6.       Do an update

 

Don’t forget to keep the old dsns and have a rollback plan just in case.

Subject: [THIN] Migrate SQL Datastore to another SQL Server

 

Hi

I will be migrating my CPS 4 farm SQL DB to another SQL Server.  SQL versions are not changing.  Im simply moving the DB from a single SQL Server to a SQL cluster.  Ive never moved a Datastore so I was hoping someone could validate these steps for me.

1. Back up the existing farm database and restore the database to the new SQL Cluster.

2. From a Citrix Server, create a new DSN file that points to the database restored in Step 1

3. Execute the dsmaint config command on the server with the new DSN file.

dsmaint config /user:domain\userid /pwd:password /dsn:"c:\program files\citrix\independent management architecture\mf20.dsn"

4. Stop and restart the IMA Service.

5. Verify that the server is using the correct DSN by checking at the following registry setting:

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\DataSourceName

6. If the IMA Service started successfully, copy the DSN file created in Step 2 to all servers in the farm.

7. Execute the dsmaint config command to change the IMA service configuration on all servers in the farm.

8. Stop and restart the IMA service on all servers in the farm.

9.  Create new Published Application.  Ensure DB is working correctly.


In relation to the steps above, I have a few questions:

1) Is there a Preferred server order I should follow?  Should the Zone Data Collector be done last?
2) If I copy the DSN to all servers, wont the DSN be wrong on all servers as the information within the file will be specific to the first server it was copied from.  IE WSID field
3) The Server in question which I am migrating off also holds the RMSummaryDB.  Whats the best way to migrate this?

Thanks
Angela
