HBOH004E The user exit module module_name cannot obtain an access list entry token (ALET). Return code: return_code
Because an error occurred when the specified user exit tried to obtain an ALET, the user exit was deleted from the MVS™ installation exit. z/OS® SYSLOG messages are not written to the data space until the error is resolved, and the user exit is reinstalled.
The specified return code is from the ALESERV service. Correct the problem that is indicated by the code, and again add the user exit to the MVS installation exit. If the problem persists, contact IBM® Software Support.
