Inbound z/OS Connect to CICS not using pre-defined IPCONN

Question & Answer


Question

How do you make sure that CICS Transaction Server for z/OS (CICS TS) uses the pre-defined IPCONN for inbound z/OS Connect Enterprise Edition transactions? When you invoke a z/OS Connect transaction, you see that a new IPCONN (nnnnnnn#) is being defined by CICS that is being auto-installed. This is preventing you from maintaining identity propagation. You can see that the inbound task actually runs under the CICS default userid, not the userid passed by the the z/OS Connect request.

Answer

Add attributes zosConnectApplid and zosConnectNetworkid to your IPIC connection in the server.xml (your zosconnect_cicsIpicConnection element).

This is documented as follows in topic Configuring an IPIC connection in CICS of the z/OS Connect EE documentation:

When z/OS Connect EE connects to CICS, it flows the zosConnectApplid and zosConnectNetworkid values that are defined on the zosconnect_cicsIpicConnection element in server.xml. If these values match the Applid and Networkid attributes of an IPCONN definition, then that definition is used to install the connection.

Ensure that these parameters match the Applid and Networkid of the predefined IPConnection resource in CICS.

In this case, a change was made for the definition in z/OS Connect to use: zosConnectNetworkid="ZOSCON1" zosConnectApplid="ZOSCON1"

instead of: cicsNetworkid="ZOSCON1" cicsApplid="ZOSCON1"

After making this change, the pre-defined IPCONN was acquired after the submitted request. The userid was passed into CICS and used by the transaction.

See Configuration Elements in the z/OS Connect EE documentation for more details
