DFS2867A EXTERNAL TRACE NOT USABLE, REPLY "Y" TO USE OLDS, "N" TO TRACE INCORE

Explanation

IMS cannot use the external trace data sets for one of the following reasons:
  • No external trace dynamic allocation members were found, or dynamic allocation of the found members failed.
  • The block size of the output data set is less than 4008 bytes.
  • Open, close, or write errors forced the termination of the external trace services.

This message is usually preceded by other IMS External Trace error messages explaining why External Trace is not usable.

Operator response

Respond with Y for IMS trace tables to be logged to OLDS. When OLDS logging is external, tracing to OLDS continues until all trace logging stops. Respond with N for IMS tracing to be in memory only. External trace initialization is attempted again if a trace is subsequently started with the LOG option.
