 Hi Sunil,

After you run -rebuildIndices and -reindex all you then continue with exporting the database to .tar files.
Once you have exported all the databases, change the database configuration settings in teamserver.properties of jazz.
Oracle DBs should already be set up and configured properly.
Now, you will run repotools -import  from the previously exported .tar DB files. This action takes the data from the file and inserts them into the Oracle Database according to your changed settings in teamserver.properties.
If data architecture needs to be changed because of different DB vendor, the previous command does it all.

Hi Adam,
        Please review below steps as per our understand we have noted down them for Database migration from SQL to Oracle.
1.Stop Application(CLM 6.0.6) and Database server(SQL 2014).
2.Backup Application and Database server.
Oracle Database related
1. Install Oracle 12c
2. Need to create Database for each application ex:CCM,QM,JTS,RM(Same name As in SQL currently).
3. DB Password must be same as Current SQL.
# Do we need to create the DB Tables for each application?? or will take from Import export activity.
3.Run the repotools -addTables command.
4.Rebuild and reindex the index files for all installed applications: For Jazz Team Server:
5.Export your data to .tar file for each application:
6.Changes in Teamserver.properties and points to new Oracle DB for each application
7.Import the data from the .tar files by entering the repotools command.

8.Start Server 


Thanks in advance.

 Hi Sunil,

DB password may be changed if needed (you can edit it in temaserver.properties)
Yes, you need to create DB tablespace (not tables) in Oracle server before running the import.

Do not run -addTables command, the -import proccess will do it instead.

All other points are correct.

HINT: After you reconfigure teamserver.properties with new DB configuration you may run repotools -verify  command to check if the applciation is able to communicate with new database.

Please check this short article describing moving DNG database from Derby to Oracle in more detailed way. I think it woud help you (the process is the same for other databases): https://jazz.net/wiki/bin/view/Deployment/MigratingDNGDBFromDerby2Oracle

In case you need direct support with anything related to Jazz, you can find us at www.softacus.com :)

Please note:

  1. The export and the import can be very time consuming.
  2. Setup  an isolated test system and test the procedure to find out you do it right and get a baseline for how long it takes.
