Populating DB_LAST_UPD Columns
If your Siebel implementation uses an Oracle or DB2/UDB database, then SSSE performance optimization requires that you place data in the DB_LAST_UPD column of each of the Siebel tables listed in Table 14. These columns were added to the listed tables specifically for use by SSSE. When SSSE makes queries related to these new columns, Oracle and DB2/UDB database optimizer performance improves if the columns contain data.

The following procedure briefly describes how to populate these columns with the recommended data. NOTE: This task is highly recommended for Siebel implementations that use Oracle or DB2/UDB databases. This task is not needed for Siebel implementations that use other database types.
To populate DB_LAST_UPD columns with data
- For each Siebel table that is listed in Table 14, use one of the following methods to place data in the DB_LAST_UPD column of at least some rows:
- After you have used a script or database triggers to populate the DB_LAST_UPD columns with data, update your database statistics and then modify your database optimizer so that it is forced to consider the DB_LAST_UPD indexes.
NOTE: It is not possible to force a Microsoft SQL Server database optimizer to consider DB_LAST_UPD indexes.
