If TRAPFWD is not running

If TRAPFWD is not already running, specify the -d parameter during startup. You can start the TRAPFWD trace in one of the following ways:

• Through the start options in the JCL used to start the TRAPFWD. For example,

  //TRAPFWD EXEC PGM=EZASNTRA,REGION=4096K,TIME=NOLIMIT,
  //PARM='POSIX(ON) ALL31(ON)/-d 3'

• Through OMVS, using the trapfwd command. For example,

  trapfwd -d 3 &

Use one of the following trace levels:

1

Minimal tracing, trace address from which the trap is received.

2

In addition to 1, trace addresses to which the trap packet is forwarded.

3

In addition to 2, trace trap packets.
