Running CONNX for CICS/VSAM - OS/390 / z/OS Uninstallation Without Shutting Down CICS

You can perform a partial uninstallation of CONNX without shutting down the target CICS region as follows:

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

NX01 STOP
 

  1. Next, use the CEMT transaction to close and disable the CONNX VSAM configuration and sample files:

CEMT SET FI(CNX*) CLO DIS
 

  1. Edit the @REMOVE JCL member and delete all references to the CONNX load library and the CONNX SAS/C QSAM sequential data sets:

CONNX.CICS.STDERR                    
CONNX.CICS.STDOUT                    
CONNX.CICS.STGRPT   

  1. Submit the modified JCL and navigate to a different ISPF option so that the CONNX.VVRR.CNTL PDS is also deleted:

  2. After this job completes and the target CICS region is shut down, you can follow the steps described in Manual Steps: CONNX for CICS/VSAM - OS/390 / z/OS to complete the CONNX uninstallation.
