To uninstall CONNX for VSAM - VSE

Given a default CONNX installation library name of CNXVVVRR, the CONNX installation JCL library.sublib is CNXVVRR.CNTL. Member @REMOVE0.JCL contains the batch uninstallation JCL.

  1. Log on to the target CICS partition and stop the CONNX NX00 TCP/IP listener transaction NX00 by entering:

NX01 STOP

  1. Next, shut down CICS by entering:

CEMT PERF SHUT IMMED

  1. After the CICS partition shuts down, you can submit the JCL in member @REMOVE0.JCL via the CICS Ditto transaction. Note that the first control record of the // EXEC LIBR step deletes the CNXVVRR.CNTL library.sublib, so be sure to submit the job and deallocate the CONNX library by exiting from the CICS Ditto transaction.

  1. The IDCAMS DELETE step should return zeroes for all CONNX data sets which exist and are not allocated to another VSE process or job. The EXEC LIBR step to delete the CONNX VSAM-managed library and sublibraries may return an informational message to the effect that the deletes should be performed with Access Method Services. The CICS RDO DFHCSDUP utility step should return zeroes for deletion of the CNX0809 group. The final IDCAMS DELETE step removes the VSAM cluster which contains the CNXV8R8 library. The last IESVCLUP step removes the standard label for the CNXVVRR library, if one was created during installation.
