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 for IMS Connect -

�WITH Energizer for IMS Connect:

- Intelligent Management of IMS OTMA Transactions and ODBM DRDA Requests

� DataStore Router– Route transactions and balance the workload among active datastores

� ODBM Router– Route DRDA requests and balance the workload among active ALIAS /

Datastores� Workload Governor

– Prevent bad applications and runaway transactions from overloading your


� Workload Governor– Prevent bad applications and runaway transactions from overloading your

system

� Exit Services– Dynamically define / manage / reload exits and processing options without

recycling IMS Connect

� Security Services – Provide enhanced security at the IMS Connect level

� Statistics & Diagnostics– locate where a problem occurs, understand the transaction workflow, collect

information and provide real time and historical reporting

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


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