The members found in the XCOMCNTL library, how are they loaded or enabled into XCOM storage? Can this be done automatically? I noticed some members in effect by issuing /F XCOM,LIST, GROUP/LU, and wondered how they were enabled.
There are two ways destination members may be loaded
- At startup of the CA XCOM task.
- With a modify command.
In the default table or config member, there is a parameter START. This specifies the name of a special entry in the ...XCOMCNTL (control) dataset which contains a list of the members that should be enabled when the task comes up. For example,
This is the default value. You can specify a different name with this parameter.
The ...XCOMCNTL(XCOMSTRT) member looks like this (the comment is optional):
* START MEMBER FOR SERVERS
As you can see, it is just a list of the names of destination members.
You can see this happening at the beginning of the XCOMLOG:
Then followed later by the list of destination members being enabled
XCOMCNTL XCOMM0559I SERVER2 ENABLED SUCCESSFULLY
XCOMCNTL XCOMM0559I SERVER3 ENABLED SUCCESSFULLY
With a MODIFY Command
Individual destination members may be enabled with the modify command:
where XCOM is the name used to start the CA XCOM server. This setting lasts until the server is brought down.
Individual destination members may be disabled (removed) with the modify command:
This setting lasts until the server is brought down.
For additional information and options, please refer to the XCOM z/OS 12.0 documentation - Section How to Enable and Disable a Destination Member.
