Indexes
Verify that all indexes exist for the tables involved. In most implementations, the tables and corresponding indexes in the following list tend to be the most heavily used and should be separated across devices. In general, the following indexes should be on different physical devices from the tables on which they are created.
S_ACCNT_POSTN
S_OPTY
S_ADDR_ORG
S_OPTY_POSTN
S_CONTACT
S_POSTN_CON
S_DOCK_TXN_LOG
S_PARTY_RPT_RE
S_SRV_REQ
S_EVT_ACT
S_OPTY
S_ORG_EXT
For organizations that plan to use EIM extensively, you should put your key EIM tables (based on your unique business requirements) on different devices from the Siebel base tables, because all tables are accessed simultaneously during EIM operations.
You can speed up deletes and merges involving S_ORG_EXT by adding an index to one or more columns. For more information, see Siebel Performance Tuning Guide.
