DFS4760E UNABLE TO ALLOCATE CTC DEVICE, MSPLINK msplink, ADDR addr
Explanation
IMS restart processing attempted to re-create a dynamic MSC channel-to-channel (CTC) physical
link (MSPLINK) that was created during a previous instance of IMS by using a CREATE
MSPLINK command. However, the request to dynamically allocate the CTC device failed. The
following conditions are some of the possible reasons that cause this error:
- Another IMS system on the same logical partition (LPAR) has created a dynamic MSPLINK that uses the same CTC address.
- The CTC device was modified offline or detached from the IMS system.
- Available storage is not enough to process the dynamic allocation request.
In the message text:
- msplink
- The name of the physical link.
- addr
- The CTC device address.
System action
If the problem is internal to the IMS system, such as storage unavailability, IMS restart processing abends, usually with the abend code U0168.
If the problem is external to the IMS system, IMS restart processing continues and the dynamic MSPLINK is created. However, the new dynamic MSPLINK is not usable for MSC communications, and the status of the dynamic MSPLINK is NOTOPEN.
Output destination
The z/OS system console.
Operator response
Use appropriate MVS commands to determine why the CTC address is not available.
To enable communications for the dynamic CTC MSPLINK, complete the following steps:
- Delete the existing MSPLINK by using a DELETE MSPLINK command.
- Create the MSPLINK by using a CREATE MSPLINK command to allocate the CTC device again.
