3. 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

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
