Information in this document applies to any platform.
During the upgrade of the Siebel 220.127.116.11 database to the targeted Siebel Innovation Pack 18.8 version, the creation of seven of the S_EVT_ACT indexes takes approximately 11 hours of the 20 hours which is the total upgrade time.
These indexes are the following:
S_EVT_ACT_F42 Index Creation 1:14:42.831h
S_EVT_ACT_F82 Index Creation 1:46:50.384h
S_EVT_ACT_F83 Index Creation 1:27:24.942h
S_EVT_ACT_F84 Index Creation 1:28:21.837h
S_EVT_ACT_F85 Index Creation 1:28:15.635h
S_EVT_ACT_F86 Index Creation 1:28:13:101h
S_EVT_ACT_F87 Index Creation 1:26:03.951h
The size of the S_EVT_ACT is 334 GB for 194,715,786 rows.
This time is not acceptable. How can the performance be improved for this specific step (creation of the above indexes)?
