Situation Description

Transaction database calls high

 

Suggested Actions

This situation triggers when the number of DL/I database calls for a transaction instance (UOR) exceeds the specified threshold. This can indicate that the transaction being processed is in a loop or that it is poorly designed. A high database call count can cause database buffer pools to fill and force other database records in the pools to be written to their database, which can cause IMS to perform excessive I/O.
