To verify that all CONNX for Adabas components have been uninstalled, use ISPF option 3.4 to list and delete the datasets defined with the (default) CONNX.ADABAS high-level qualifier. Next, delete all versions of  the CNXADA procedures from the production JCL PROCLIB. Finally, if the CNXSTOP REXX exec file has been copied to a SYSPROC PDS such as SYS1.LOCAL.CLIST, delete the CNXSTOP member.
