IMS Connect Considerations

�WITHOUT Energizer for IMS Connect

- No Dynamic Functionality Changes� IMS Connect must be recycled for any change

- User Exits� Assembler exits must be coded and maintained

� Enhanced functionality is the customer’s responsibility and must be coded in the user exits

– Workload Balancing

– Workload Balancing

– Resource Availability Checking

– Security

- Minimal Information� Statistics are not available

- Diagnostics� Problem resolution can be difficult

Energizer Walkthrough 2 – Timeout Issues –Possible Resolutions

Increase IMS Connect Client TIMER value via Timer Override or Application

Check and adjust EXPRTIME value on the IMS Transaction. This will save CPU processing time due to the fact that IMS discards the transaction input if the transaction is not scheduled within the EXPRTIME limits.

Compare and review of using IRM F1 (CLIENT IRM HEADER) -IRM_F1_TRANEXP This value overrides the IMS transaction EXPRTIME
