Trace Facility Functionality

The CA Ideal Trace Facility provides the following functions:

VPE service trace (@I$TRACE).

This function records all CA Ideal service routines called and CA IPC service macros invoked during a specified part of a CA Ideal session. It generates entries for all CA Ideal online and batch services requested (except those that invoke asynchronous tasks online). It includes a facility to extract and print selected entries.

DIAL trace (@I$DIALMASK).

DIAL stands for Debugging Interface for Assembly Language. This facility records internal diagnostics CA Ideal modules executed as a result of a RUN, COMPILE, or CATALOG command or the Source Transport Utility produce.

Object Module List command (@I$CALL ADPOBJ)

This function provides dumps of VLS object modules.

The Object Module List is described later in this chapter. The VPE and DIAL traces are described as follows.

The following graphics illustrate the data flow of the VPE and DIAL traces under z/OS and VSE. There are significant differences between the way the traces work online and in batch. These differences are described afterward.

z/OS trace facility flow is as follows:

VPE VPE Trace (Online) Output Trace --------> File ---------> Extract -------> Member ADRTRC Data OUTTRACE | | | (Online/ | (Batch) | Batch) | DIAL --------> | | Trace | (Batch) | DIAL-Only File Print File SYSDIAL AUXPRINT

VSE trace facility flow is as follows:

VPE VPE Trace Trace --------> File ---------> Extract ADRTRC Data | | | (Online/ | (Batch Only) | Batch) | DIAL --------> | | Trace | (Batch) | DIAL-Only File System SYSLST Printer
