Starting a Security Trace in the IUI (ISPF)

Edit online

You can start a security trace to debug security problems in the IUI.

Procedure

  1. To allocate a security trace for the IUI, enter the following command:

    TSO ALLOC FI(APISECUR) DA(*) /* FOR ZOS */

    Note: As an alternative, to send the information to a preallocated data set with attributes of RECFM=VBA, LRECL=121, and BLKSIZE=125, you can enter the follow command:

    TSO ALLOC FI(APISECUR) DA('$hlq.APISECUR.TRACE')OLD

  2. Log on to the DTF and carry out any commands you want traced. Trace information is written to the screen immediately upon signon. Sign off when finished.
  3. To stop the security trace, issue the following command:

    TSO FREE FI(APISECUR)        /* FOR ZOS */
