DFS4768E ERROR DETECTED DURING AUTOMATIC IMPORT OF MSC CTC LINK, MSPLINK=msplink, ADDR=addr, RC=rc

Explanation

An error occurred during the automatic import of an MSC CTC physical link definition from the IMSRSC repository during IMS cold start.

In the message text:
addr
The CTC adapter device ID that is used for the MSC CTC physical link.
msplink
The CTC physical link name that is imported from the IMSRSC repository.
rc
Indicates the reason for the failure.
8
The CTC device is not available.
12
The CTC adapter device number is not a CTC device.
16
Dynamic allocation of CTC device failed.
20
Failed to open the CTC DCB
24
No DDNAME is available.

System action

IMS cold start continues and the CTC physical link definition is imported, but the CTC link is not usable for IMS communications.

Output destination

This message is sent to the z/OS® system console.

Operator response

Complete one of the following actions to enable communications for a CTC physical link that is not usable:
  • Delete the CTC physical link by using the DELETE MSPLINK command, and then re-create the CTC link with a valid CTC adapter device number by using the CREATE MSPLINK command.
  • Use the UPDATE MSPLINK command to update the existing definition with a valid CTC adapter device number.

Before you create a new CTC physical link or update the existing CTC physical link, ensure that the CTC adapter device number is prepared in your system and that the CTC physical link in the partner system is also prepared.

Problem determination

  • For return code 8, use MVS commands to determine why the CTC adapter device ID failed for dynamic allocation. The device might be offline or used by another system.
  • For return code 12, check the system and ensure that a device is a CTC device.
  • For return code 16, this is a system error.
  • For return code 20, open DCB failed.
  • For return code 24, all DDNAMEs from DFSM0000 to DFSM9999 are in use.
