FLUSH_DATA Function	Flushes profiler data collected in the user's session.
PAUSE_PROFILER Function	Pauses profiler data collection.

START_PROFILER Function

This function starts profiler data collection in the user's session.

Syntax

There are two overloaded forms of the START_PROFILER function; one returns the run number of the started run, as well as the result of the call. The other does not return the run number. The first form is intended for use with GUI-based tools controlling the profiler.

The first form is:

DBMS_PROFILER.START_PROFILER(run_comment IN VARCHAR2 := sysdate,
run_comment1 IN VARCHAR2 :='',
run_number OUT BINARY_INTEGER)
RETURN BINARY_INTEGER;

The second form is:

DBMS_PROFILER.START_PROFILER(run_comment IN VARCHAR2 := sysdate,
run_comment1 IN VARCHAR2 :='')
RETURN BINARY_INTEGER;

Parameters

Table 46-6 START_PROFILER Function Parameters

Parameter	Description
run_comment	Each profiler run can be associated with a comment. For example, the comment could provide the name and version of the benchmark test that was used to collect data.
run_number	Stores the number of the run so you can store and later recall the run's data.
run_comment1	Allows you to make interesting comments about the run.

STOP_PROFILER Function

This function stops profiler data collection in the user's session.

This function has the side effect of flushing data collected so far in the session, and it signals the end of a run.

Syntax

DBMS_PROFILER.STOP_PROFILER 
  RETURN BINARY_INTEGER; 

FLUSH_DATA Function

This function flushes profiler data collected in the user's session. The data is flushed to database tables, which are expected to preexist.

Syntax

DBMS_PROFILER.FLUSH_DATA 
  RETURN BINARY_INTEGER; 

PAUSE_PROFILER Function

This function pauses profiler data collection.

RESUME_PROFILER Function

This function resumes profiler data collection.

GET_VERSION Procedure

This procedure gets the version of this API.

Syntax

DBMS_PROFILER.GET_VERSION ( 
   major  OUT BINARY_INTEGER, 
   minor  OUT BINARY_INTEGER); 

Parameters

Table 46-7 GET_VERSION Procedure Parameters

Parameter	Description
major	Major version of DBMS_PROFILER.
minor	Minor version of DBMS_PROFILER.

INTERNAL_VERSION_CHECK Function

This function verifies that this version of the DBMS_PROFILER package can work with the implementation in the database.

Syntax

DBMS_PROFILER.INTERNAL_VERSION_CHECK 
  RETURN BINARY_INTEGER;
