Securing AIX Memory Allocation Segment Space for the Siebel Database

Upgrades from: All Siebel releases.

Environments: Development, production test, production.

Databases: All databases. (Exception: this topic does not apply to Microsoft SQL Server.)

Platforms: UNIX only.

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

Before you run an upgrade on AIX, set the following environment variable on the AIX machine that you are using for the upgrade:

setenv LDR_CNTRL LOADPUBLIC@MAXDATA=0x60000000

This will prevent a shortage of memory allocation segment space that might occur on the machine where both the Siebel Database Server and Siebel Server are installed. After a successful upgrade, reset this parameter to the original value.
