DFS2145 MESSAGE LOST DURING LINK RESTART LINK xxx.
Explanation
During synchronization of the link, IMS detected that this system has lost one or more messages that the other system has not yet received. The difference between the DEQ count on this system and the received count on the other system will be the count of messages lost.
System action
IMS logs the error information using a type X'6701' log record. The link is stopped by PSTOP. The restart block is updated so that a subsequent restart link will work; however, the messages will remain lost.
Operator response
Verify that both IMS systems were correctly restarted (a cold start or restart from the wrong checkpoint could cause this). Restart the link again. The link should restart, but the messages will remain lost.
Programmer response
The log data sets from both systems will have to be analyzed to determine why the messages were lost. If the error occurred following an IMS warm start, then the restart log data set will also have to be analyzed. (You will need to print type 40, 66, and X'6701' records.)
Problem determination
36. Include as documentation the master terminal output and IMS log data sets from both systems. If IMS was warm started, then include the restart logs also.
