Uninstalling CONNX for CICS/VSAM-zOS
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
2. Use the CEMT transaction to close and disable the CONNX VSAM configuration and sample files:
CEMT SET FI(CNX*) CLO DIS
3. 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
4. Submit the modified JCL and navigate to a different ISPF option so that the CONNX.VVRR.CNTL PDS is also deleted.
