When reporting problems to the IBM Support Center, you might be asked to provide trace output for all or part of the DFSMSrmm ISPF dialog. With tracing on, you see the REXX procedure statements as they are processed and the RMM TSO subcommands that the DFSMSrmm ISPF dialog is building. Use the trace output to help determine if the error occurred within the REXX procedure or as a result of an error in the RMM TSO subcommand issued by the DFSMSrmm ISPF dialog.

You can trace the processing of a DFSMSrmm function by using the TRACE command as described in Figure 1. You specify the TRACE command by coding it in the DFSMSrmm ISPF dialog. You can use ALL to request both function and EXEC tracing. Specify DATASET to trace DFSMSrmm data set related processing. You can trace the processing of the RMMISPF EXEC by using the TRACE command with an EXEC name suffix. See DFSMSrmm trace command suffixes for a list of EXEC name suffixes you can use with the trace command.

Figure 1 shows the TRACE command and the keywords you can use with the command.

TRACE

Use with any operand to turn tracing on. Use it without an operand to display the active trace options.

OFF

This turns tracing off.

You can use OFF with a keyword or suffix to selectively turn off tracing. The trace command function keywords describe DFSMSrmm functions. You can specify any of the following: CONTROL, DATASET, OWNER, PRODUCT, RACK, VOLUME, and VRS. To turn off tracing for a DFSMSrmm EXEC, use a suffix.

ALL

This traces all DFSMSrmm function and DFSMSrmm EXEC processing.

CONTROL

To trace LISTCONTROL information about DFSMSrmm installation options.

DATASET

To trace data set related processing within DFSMSrmm.

OWNER

To trace owner information related processing within DFSMSrmm.

PRODUCT

To trace product information related processing within DFSMSrmm.

RACK

To trace rack number or bin number related processing within DFSMSrmm.

VOLUME

To trace volume related processing within DFSMSrmm.

VRS

To trace vital record specification related processing within DFSMSrmm.

suffix

Specify a suffix which is a DFSMSrmm EXEC name without the EDGR prefix. Suffix can be up to four alphanumeric characters.
