TraceDisableActivity

Description

Disables logging of the specified trace activity.

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!

  • ActUser! -- Occurrences of an activity you selected


Return value

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

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")
