IBM RFE for CTG To Support Insertion of AppDynamics Unique Transaction ID Into ODR Data Field

Our Mainframe event Acquisition System (MEAS) software product is integrated with AppDynamics Application Performance Monitor (APM). This integration allows APM to monitor transactions that cross platform boundaries, such as from a Windows Application Server to CICS Transaction Gateway (CTG) and CICS TS on z/OS and back. When the transaction is initiated on the distributed systems platform, APM injects a unique transaction correlation id into the transaction header.
When the transaction makes the transition from distributed systems to z/OS and uses the IPIC protocol, CTG creates an ODR, then calls CICS TS. When CICS TS sees that an ODR has already been created, the call to exit XAPADMGR does not take place. In this case, we cannot populate the ODR with the APM created unique ID to continue to track the transaction.

We respectfully request an option be added to CTG which when set, would indicate to CTG that it should not create ODR data. This then will allow the XAPADMGR exit in CICS to be called where we can insert the APM unique ID in the ODR.

    Correct - we would like to be able to inject our existing unique ID into the USERCORRDATA field, in CTG T2 exit, regardless of run time environment or communications protocol.

    Today, CICS TG creates the ODR, and optionally sets a correlation value in the USERCORRDATA field - only for JEE applications running in WAS 8.5. For IPIC connections, XAPADMGR is not triggered. The proposal is simply to open up the setting of USERCORRDATA to other CICS TG APIs, and other CICS TG application run time environments (any JEE application server, purse Java applications, .NET Framework-based applications. 

    XADAPMGR would still not be triggered for IPIC connections from CICS TG - we are not proposing to change that.

    Thank you very much for your reply. Am I correct to understand that you are indicating that we can inject our existing unique id that is passed to us from an open-system application call to CTG and place that value in USERCORDATA? Then USERCORRDATA will be passed to the XAPADMGR and TRUE exits in any/all CICS regions used in the business transaction?

    There is a misapprehension built into the request, in that the removal of ODR data within CICS TG components connecting to CICS using IPIC, will not then result in XAPADMGR being called. A more realistic proposal would be for some mechanism to be built into the CICS TG APIs, allowing the injection of a value for use as USERCORRDATA. Please provide an indication as to whether this alternative proposal would suit your requirements.
