Siebel 21.4 Update PostInstallDBSetup Utility Is Modifying DESC Sort Indexes to ASC
(Doc ID 2789946.1)
Last updated on OCTOBER 01, 2023
Applies to:Siebel CRM - Version 21.4 to 22.3 [Release V17]
Information in this document applies to any platform.
The Siebel 21.4 PostInstallDBSetup utility was executed and it took 6 hours to run in the Performance Testing environment.
It was noticed that many indexes were modified by verifying the import_cus_schema.log file.
The indexes modified in this log were all indexes that have DESC sort order columns and these indexes modification took around 5 hours to execute.
It seems that PostInstallDBSetup is modifying the indexes from DESC to ASC sort, because the ddlimp utility does not have the /9 Y switch parameter.
The issue can be reproduced as following:
1. Run Siebel Postinstalldbsetup manually (Instructions to run postinstalldbsetup can be found in
Check each setup.ini parameter meaning in Siebel Database Upgrade Guide > Chapter 10 Upgrading the Siebel Database > Post Installation Database Update);
2. Check Siebel-root\siebsrvr\log\PostInstallDBSetup_<date-time>\SeedSchemaManifest_<date-time>\Common\import_cus_schema.log file. These indexes contain columns in DESC order and were recreated in ascending order, which may affect performance. (This log snippet shows an execution in a standard environment. The S_EVT_ACT table did not contain many records.)
