Using EXEC CICS SIGNON and SIGNOFF

Once you have enabled and configured user impersonation, you can change the user account for a session by invoking EXEC CICS SIGNON.

After successfully invoking EXEC CICS SIGNON, all subsequent transactions in that session run under the logged on user's identity.

You can immediately revert the session to the default identity by invoking EXEC CICS SIGNOFF.

Note: EXEC CICS SIGNON takes effect with the next transaction, whereas EXEC CICS SIGNOFF takes effect immediately, in mid-transaction if a transaction is running. This is the same behavior as EXEC CICS SIGNON/SIGNOFF on the mainframe.
