This Knowledge Document describes how to Suppress TSO messages in CA Workload Automation ESP Edition.
If your TSO user ID is considered the owner of the event, then whenever the event triggers, its generated messages will be sent to you. As a result, when you logon, you may get many TSO messages.
Here is a way to suppress the TSO messages in ESPPARM by adding:
As stated in the Installation and Configuration Guide,
The TSOSEND initialization parameter applies either when no mailbox is specified in the Event definition or when a mailbox is specified and a TSOUSER parameter is included in the mailbox definition. The TSOSEND command does not apply to messages that the NOTIFY and SEND commands initiate.
One thing to stress, this parm will affect ALL TSO users on this ESP Edition system. If you ONLY want to suppress TSO messages for one specific user, you can do the following:
Then TSO user USER1 will not get TSO messages, but other TSO users won't be affected.
