Configuration Parameters

Limit base tables and columns to be processed. Four EIM parameters can help improve performance by limiting the affected tables and columns:

• ONLY BASE TABLES

• IGNORE BASE TABLES

• ONLY BASE COLUMNS

• IGNORE BASE COLUMNS

The ONLY BASE COLUMNS parameter is critical for the performance of an EIM process updating a few columns in many rows.

Note: Do not use the IGNORE BASE COLUMNS parameter for merge processes or export processes. This parameter should only be used for import processes and delete processes.

For other suggestions involving parameter settings, see Parameter Settings Optimization for EIM.
