Troubleshooting › How You Respond to Control File Access Delays › Message MIM0061W

Message MIM0061W

Message MIM0061W tells you that an external system that was active at startup time now appears to be inactive.

This warning message is issued by CA MIM when a system stops updating its time stamp. It is also issued at startup when a system that CA MIM is expecting does not join the complex. The system must be freed (using the FREE command) at startup to allow CA MIM to properly synchronize and clear the MIM0061W message.

To resolve problems indicated by this message

1. Wait to see if the system updates its timestamp. CA MIM removes highlighting for the MIM0061W message if the system updates its time stamp.

   Is highlighting removed for the MIM0061W message?

   Yes

   The system is active.

   No

   A system may appear inactive if processing on that system is slow, another system is dominating the control file, or for some other reason. When a system displays MIM0061W messages often and that system is not inactive, consider increasing the value for the MARGIN parameter on the SETOPTION command. Through this parameter, you can tell CA MIM to wait longer before issuing MIM0061W messages. Also, you may need to tune CA MIM.

   Go to Step 2.

2. See if an active system has a RESERVE request for the control file. Look for MIM0100A messages on all other systems.

   Are other systems displaying MIM0100A messages?

   Yes

   A local task may have issued a long RESERVE request that prevents other systems from accessing the control file. Go to a system that displays the MIM0100A message and follow the procedures for responding to MIM0100A messages.

   No

   Go to Step 3.

3. See if CA MIM is being dispatched on the inactive system. To do this, issue the z/OS D A,MIMGR command several times from the apparently inactive system. Note that MIMGR is the name of the CA MIM started task.

   What response do you receive?

   None

   z/OS may be inactive. Determine whether z/OS is inactive, and take corrective action.

   Message IEE115I

   Look at CPU use on each IEE115I message. Does CPU use change?

   • No-CA MIM is not being dispatched. See which task on that system is preventing other tasks from being dispatched and correct the error.
   • Yes-Go to Step 4.

4. See if the inactive system failed. To do this, issue a DISPLAY SYSTEMS command from the apparently inactive system.

   What response do you receive?

   None

   A hardware or software failure occurred on that system. You may need to complete a system reset (to clear the channel to the device) and then complete an IPL on that system.

   If you are sure the system will not recover immediately, and the system is not currently using any resources, then free resources and devices held on that system. To do this, issue a FREE command on another system. For example, to free resources held on system A1, issue a FREE A1 command from another system.

   Important! Integrity exposures can occur if you issue the FREE command for a system that is still actively using resources managed by CA MIM.

   Note: For more information about possible integrity exposures when using the FREE command, see Product Termination Considerations.

   Message IEE305I

   CA MIM failed on that system. Restart it on that system as soon as possible.

   Other response

   Go to Step 5.

5. See if the inactive system is migrating to a new control file. To do this, issue a DISPLAY SYSTEMS command from any system. Then, find the line for the inactive system on the MIM0108I message you receive.

   What value appears in the STATUS field?

   AWAKENING

   The apparently inactive system migrated to a new control file. Other systems will also migrate to that control file. Do not take action.

   MIGRATING

   Migration is underway. Wait 60 seconds to see if it completes. If migration does not complete in 60 seconds, then respond to the outstanding migration message on that system.
