Enterprise Integration Manager (EIM) interacts with data objects (tables and columns) via SQL statements. How those queries are executed by the database in use is directly related to the EIM performance. Since optimization modes used by Siebel application differ among database platforms, index hints usages by EIM are different.

There are two EIM parameters related to index hints:

 USE ESSENTIAL INDEX HINTS (TRUE by default)
USE INDEX HINTS (FALSE by default)

Below are suggested settings of the two parameters on different database platforms.

1. Oracle

USE ESSENTIAL INDEX HINTS = TRUE
USE INDEX HINTS = TRUE

2. MS SQL Server

USE ESSENTIAL INDEX HINTS = TRUE
USE INDEX HINTS = FALSE

3. DB2
