5.7 PLVcmt: Commit Processing

The PLVcmt (PL/Vision CoMmiT) package provides a programmatic interface to the execution of commits, rollbacks, and the setting of savepoints. See Chapter 20, PLVcmt and PLVrb: Commit and Rollback Processing for details.

5.7.1 Controlling commit activity

PROCEDURE turn_on;

Enables commit processing in PLVcmt. This is the default.

PROCEDURE turn_off;

Disables commit processing in PLVcmt. When this program is called in the current session, the COMMIT statement will not be executed.

FUNCTION committing RETURN BOOLEAN;

Returns TRUE if commit processing is being performed by PLVcmt.

5.7.2 Logging commit activity

PROCEDURE log;

Requests that, whenever a COMMIT is performed, a message be sent to the PL/Vision log.

PROCEDURE nolog;

Do not log a message with the COMMIT.

FUNCTION logging RETURN BOOLEAN;

Returns TRUE if currently logging the fact that a commit was performed by PLVcmt.

5.7.3 Performing commits

PROCEDURE increment_and_commit (context_in IN VARCHAR2 := NULL);

Increments the counter and commits if a commit point has been reached.

PROCEDURE perform_commit(context_in IN VARCHAR := NULL);

The PLVcmt package's version of COMMIT . I could probably get away with calling this program commit , but I avoid using keywords even when the compiler doesn't seem to get confused.

5.7.4 Managing the commit counter

PROCEDURE commit_after (count_in IN INTEGER);

Sets the break point at which a commit is performed. In other words, when the package-based counter reaches the specified number, issue a COMMIT. The default is to commit after the counter reaches 1.

PROCEDURE init_counter;

Initializes the PLVcmt counter referenced by the increment_and_commit program to perform incremental commits.
