Increasing the amount of PDA tracing performed

Some PDA trace points are conditional, meaning that you can specify to DFSMShsm whether or not to write the trace point to the PDA output data set. Keep in mind that once you turn off the tracing, you may need to again enable tracing to recreate problems.

Table 1 lists the current conditional PDA trace points:
