Advanced Oracle PL/SQL Programming with Packages

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 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 ...
