If it is determined that you need to back off the Directory Reader Diagnose Code, the following solution will help you accomplish that.
Before the Directory Reader diagnose is removed, all the CA VM: products that have been upgraded to use SES, must be logged off and revert back to the AIM releases, or, the prior install method.
CA does not support any of the new SES-installed releases of the CA VM: products when the Directory Reader Diagnose is not operational. Failures that can occur when it is not installed are not documented. Installing the Diagnose is required in order to run the CA Mainframe VM Product Manager and required to install, deploy, service, and operate all of the VM:Manager suite of products.
CPXLOAD may be used to load code or messages into CP for multiple purposes. Our use does not involve any exits or messages. Our use is to load code for a diagnose instruction and a simple CP command.
Our setup instructions say:
CPXLOAD VMNDLK TEXT * NOCONTROL LET TEMPORARY DEFINE DIAGNOSE 100 ENABLE EPNAME VMNDLKUP ... ... PRIVCLASSES E CHECKR15 YES DEFINE COMMAND VMNDLK ENABLE EPNAME VMNDLKCP ... PRIVCLASSES E IBMCLASS E
To back out of this setup:
DISABLE DIAGNOSE 100 DISABLE COMMAND VMNDLK CPXUNLOAD ID nn
(To get the ID number "nn", issue Q CPXLOAD and read the command response.)
