Securing AIX Memory Allocation Segment Space


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 if the Database Server and Siebel Server are installed on the same machine.

After a successful upgrade, reset this parameter to the original value.
