How to determine if CICS region is accessing IDMS?
We have a CICS region configured to access IDMS but not sure if it is actively doing so. Is there a be method to determine if a CICS region is accessing an IDMS CV.
Resolution
If there is an INTC interface used in a CICS region it must define the Program and the Transaction that invokes it in the CICS CSD .
Also, the INTC interface (created from CICSOPT) specifies a CWADISP, and for any actual CICS programs or UCFCICS to use that interface, they must be linked with an IDMSCINT stub that specifies the same CWADISP.
Such programs and the transactions that invoke them must be defined to the CSD as well.
The CICS admin should be able to tell you if any CICS programs have included that CINT stub and if they ever execute those programs/transactions.
CICSOPT also has a parameter that will identify the specific CICS front end ID (TPNAME) so in the CV in question you could DCMT D MEM ERE to see if any of them show the CICS frontend ID.
IF the INTC interface is started each time CICS comes up via PLT or by manually executing the transaction that invokes it, and you want to know if any CICS programs are using it, you could remove it from the PLT so the interface is NOT started.
Then if any program tries to use the interface the transaction will get 0068 error-status
