Preparing for a No-Development-Environment Siebel Upgrade

Upgrades: All upgrades.

Environments: Production test, production.

Platforms: All platforms.

This topic is part of an upgrade process. See How to Perform a Siebel Database Upgrade.

If your installation does not include a development environment, you do not need to merge your Siebel Repository. Instead, you can use the repository and schema definition files included in the Siebel Database Server installation.

Before performing the upgrade, you must move and rename these files.

To prepare for a no-development-environment upgrade

1. Navigate to DBSRVR_ROOT\common (Windows) or DBSRVR_ROOT/common (UNIX) and locate the mstrep.dat file.
2. Copy the mstrep.dat file and rename it custrep.dat.
3. Place the custrep.dat file in the DBSRVR_ROOT\DB2390 (Windows) or DBSRVR_ROOT/DB2390 (UNIX) directory.
4. In the DB2390 directory, copy the ddl.ctl file and paste the copy into the same directory.
5. Rename the copy schema.ddl.
6. In the production test environment create a new database, separate from the Siebel database.

   Install the Siebel database from the new release in the new database. Do not migrate any data to the new database.

   This database is called the reference database.

7. Define an ODBC for the reference database.
