Goal

In ODI 12.2.1 agent side, it is observed that many sessions wait for update DML on Work Repository SNP_SB table and it saturates the Repository database Sessions. The sample DML query looks like below:


This query is initiated by the agent automatically and it is not from actual job execution. The select inside the update DML seems to be the main cause of the issue.

Is it possible to create indexes on the table SNP_SESSION and SNP_SCEN to improve the performance at execution time?
