Uninstalling CONNX for VSAM - VSE
The CONNX for VSAM TCP/IP Server Setup client application transfers the CONNX components to the target VSE host via FTP. After the initial FTP step, the CONNX installation continues via a batch job submission using VSE Ditto. The final installation steps on VSE platforms consist of manual updates to the CICS target partition Destination Control Table and the startup JCL.
CONNX for VSAM provides batch uninstallation JCL for VSE platforms.
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
2. Shut down CICS by entering:
CEMT PERF SHUT IMMED
3. 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.
4. 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.
