Upgrade Guide for DB2 UDB for z/OS and OS/390 > Basic Database Preparations >

Verifying Database Server Configuration

Upgrades: All upgrades.

Environments: Development environment only.

Verify that your development Siebel Database Server configuration meets or exceeds Siebel requirements as described in Implementing Siebel eBusiness Applications on DB2 UDB for z/OS and OS/390.

• Informational APAR pq83289 is required for loading multiple tables to the same database in parallel.
• The upgrade sets the TRACKMOD parameter the default value for tablespace objects: YES.
• The DSNZPARM CMTSTAT should be set to INACTIVE to prevent timeout errors from occurring. If you do not run INACTIVE, then set IDTHTOIN to IGNORE.

CAUTION:  It is very important that the required maintenance level listed in informational APAR ii13012 is fully applied, and that all DSNZPARMs required for Siebel implementation on DB2 version 7 are set up correctly.

Before you begin your upgrade, verify your database configuration. The consequence of exceeding available resources is a halted upgrade that requires you to allocate time to adjust the environment and then resume the upgrade.

When you upgrade from a previous version of Siebel eBusiness applications to Release 7.7, expect database growth in the range of 30-50%. The amount by which your database grows may vary widely, depending on your database configuration, row size of tables, and data content.

The growth percentage will increase depending on how you size your database and configure default storage for database tablespaces. For example, if you set the default storage for your initial or next extent in a given DB2 tablespace to 10 KB, that tablespace will grow by a smaller percentage than if you set it to 100 KB.
