DFS2870W ABEND WHILE WRITING TO EXTERNAL TRACE DATASET ddname
Explanation
An abend occurred while writing to one of the external trace data sets.
In the message text:
- ddname
- The DD of the dataset for which the abend occurred.
System action
DFSTRA40 refreshes the DCB, switches to the other external trace data set and rewrites the buffers that were not already CHECKed. If another abend occurs with the same data set without a successful write, the data set is marked as not usable and the system takes the action described in message DFS2866W.
System programmer response
Nothing needs to be done if the data set is usable after DFSTRA40 recovers from the abend. If another abend occurs, the data set is marked as not usable. If the data set is successfully deallocated, the data set can be reused by stopping and restarting the external trace.
