MODULE modulename LOAD FAILED – reason

Explanation

VTAM® issues this message in response to a MODIFY EXIT command when the module modulename fails to load.

modulename is the name of the module that failed to load.

reason provides information about the cause of the load failure and can be one of the following:
DEFINED AS ALIAS IN CSLOD
Either the alias module modulename could not be located in the vector list of its load module or the alias module was loaded before the vector list.
INSUFFICIENT STORAGE
Not enough storage was available to process the load request.
I/O ERROR LOADING MODULE
An I/O error occurred when loading modulename.
I/O TIMEOUT LOADING MODULE
An attempt was made to load modulename, but a system or hardware problem has caused the module load facility to time out while waiting for I/O to complete.
LOADER INOPERATIVE
This can occur for one of the following reasons:
  • A previous module load never completed.
  • The VTAM-directed load subtask, ISTINMLS, abnormally ended during a load request.
  • The VTAM-directed load subtask, ISTINMLS, has not completed its initialization.
LOCK PROTOCOL VIOLATION
A locking protocol violation occurred while VTAM was trying to satisfy the load request.
MODULE NOT IN ISTCSLOD
modulename is not in ISTCSLOD.
MODULE NOT FOUND
The resource identified by modulename does not exist.

System action

  • If reason is LOADER INOPERATIVE, all subsequent commands that require the loader will fail. If the I/O load operation eventually succeeds, load operations are again enabled.
  • If reason is MODULE NOT IN ISTCSLOD or DEFINED AS ALIAS IN CSLOD, VTAM initialization or an activation request might fail.
  • For all other reasons, the MODIFY EXIT command is ignored, and VTAM uses the old exit.

Operator response

  • If reason is INSUFFICIENT STORAGE, enter the DISPLAY BFRUSE command. Issue the DISPLAY STORUSE command to display storage usage for storage pools. Save the system log and request a dump for problem determination. When more storage is available, reenter the command.
  • If reason is MODULE NOT FOUND, ensure that you entered the command correctly. See the z/OS Communications Server: SNA Operation for more information.
  • For the following values of reason, save the system log for problem determination.
    • DEFINED AS ALIAS IN CSLOD
    • I/O ERROR LOADING MODULE
    • I/O TIMEOUT LOADING MODULE
    • LOADER INOPERATIVE
    • LOCK PROTOCOL VIOLATION
    • MODULE NOT IN ISTCSLOD

System programmer response

  • If reason is INSUFFICIENT STORAGE, use the z/OS Communications Server: New Function Summary to review VTAM storage requirements. See the z/OS Communications Server: SNA Diagnosis Vol 2, FFST Dumps and the VIT for information about analyzing dumps and about analyzing storage using the VIT analysis tool, if external trace is active.

    If the operation is critical, deactivate some major nodes in order to free up storage for the command, and then reenter the command.

  • If reason is I/O ERROR LOADING MODULE or I/O TIMEOUT LOADING MODULE, examine your VTAMLST file to make sure the requirements for the VTAM system are correct for your system.
  • If reason is LOADER INOPERATIVE or LOCK PROTOCOL VIOLATION, contact the IBM® Support Center.
  • If reason is MODULE NOT IN ISTCSLOD or DEFINED AS ALIAS IN CSLOD, contact the IBM Support Center.
