Enabling tracing for the System Data Engine after startup

Edit online

For certain problems, IBM® Software Support might request that you enable tracing for the System Data Engine after startup by using the MVS MODIFY command.

Procedure

  1. To enable tracing, IBM Software Support might require you to run a command that is similar to one of the following lines. 
    F JOBNAME, DEBUG LEVEL
F JOBNAME, DEBUG,LEVEL
    JOBNAME
    Is the name of the job for which you want to enable tracing, for example DEV$SDE.
    LEVEL
    Is the level of tracing to be enabled.
    The exact syntax of the command will be provided by IBM Software Support when you must enable tracing. Tracing should not be enabled otherwise.
  2. Verify that the appropriate messages are written in the HBODEBUG data set after you run each command.

Results

The tracing output is in the HBODEBUG data set if it is in the JCL for the System Data Engine started task, or in the HBODUMP data set if the HBODEBUG data set is not in the JCL for the System Data Engine started task. See the following example for specifying the HBODEBUG DD.
//HBODEBUG  DD SYSOUT=*

What to do next

To disable tracing, run the following command:
F STCNAME, DEBUG CLEAR
