Syntax

TraceDisableActivity ( activity )

Argument	Description
activity	A value of the enumerated datatype TraceActivity that identifies the activity for which logging should be disabled. Values are: ActError!—Occurrences of system errors and warnings ActESQL!—Embedded SQL statement entry and exit ActGarbageCollect!—Start and finish of garbage collection ActLine!—Routine line hits ActObjectCreate!—Object creation entry and exit ActObjectDestroy!—Object destruction entry and exit ActProfile!—Abbreviation for the ActRoutine!, ActESQL!, ActObjectCreate!, ActObjectDestroy!, and ActGarbageCollect! values ActRoutine!—Routine entry and exit (if this value is disabled, ActLine! is automatically disabled) ActTrace!—Abbreviation for all activities except ActLine!

Argument

Description

activity

A value of the enumerated datatype TraceActivity that identifies the activity for which logging should be disabled. Values are:

ActError!—Occurrences of system errors and warnings
ActESQL!—Embedded SQL statement entry and exit
ActGarbageCollect!—Start and finish of garbage collection
ActLine!—Routine line hits
ActObjectCreate!—Object creation entry and exit
ActObjectDestroy!—Object destruction entry and exit
ActProfile!—Abbreviation for the ActRoutine!, ActESQL!, ActObjectCreate!, ActObjectDestroy!, and ActGarbageCollect! values
ActRoutine!—Routine entry and exit (if this value is disabled, ActLine! is automatically disabled)
ActTrace!—Abbreviation for all activities except ActLine!
ActUser!—Occurrences of an activity you selected

Returns

ErrorReturn. Returns one of the following values:

Success!—The function succeeded
FileNotOpenError!—TraceOpen has not been called yet
TraceStartedError!—You have called TraceDisableActivity after TraceBegin and before TraceEnd

Usage

Use this function to disable the logging of the specified trace activities. You typically use this function if you are tracing only portions of an application run (and thus you are calling TraceBegin multiple times) and you want to log different activities during each portion of the application.

Unless specifically disabled with TraceDisableActivity, activities that were previously enabled with a call to the TraceEnableActivity function remain enabled throughout the entire application run.

You must always call the TraceEnd function before calling TraceDisableActivity.

Examples

Example 1

This example logs the enabled activities for the first block of code to be traced. Then it stops logging and disables two activity types for a second trace block. When logging is resumed for another portion of the application run, the activities that are not specifically disabled remain enabled until TraceClose is called:

TraceEnableActivity(ActESQL!)

TraceEnableActivity(ActGarbageCollect)

TraceEnableActivity(ActObjectCreate!)

TraceEnableActivity(ActObjectDestroy!)

TraceBegin("Trace_block_1")

TraceEnd()

TraceDisableActivity(ActESQL!)

TraceDisableActivity(ActGarbageCollect!)

TraceBegin("Trace_block_2")
