Chapter 21. PLVlog and PLVtrc: Logging and Tracing
PL/Vision provides two packages to provide execution tracing and logging from within PL/SQL programs.
Use the PLVlog package to write information to a log.
Use the PLVtrc package to trace the execution of your PL/SQL programs.
Both of these packages are used by other PL/Vision packages, PLVlog in particular. For example, when you handle an exception with a PLVexc handler like rec_continue, it, in turn, calls PLVlog to log the error.
