DBMS_DEFER_SYS: Managing Deferred Transactions
The DBMS_DEFER_SYS package provides a number of programs for administrative tasks associated with deferred transactions.
How the Package Is Used
This package is used primarily to administer an advanced replication environment. DBAs can use the procedures to execute deferred transactions, to control what nodes are available for them, and to schedule their execution.
Installation and Access
The DBMS_DEFER_SYS package is created when the Oracle database is installed. The
dbmsdefr.sql

replication packages. The wrapped SQL script
prvtrctf.sql
creates the public synonym DBMS_DEFER_SYS. No EXECUTE privileges are granted on DBMS_DEFER_SYS;
only the owner (SYS) and those with the EXECUTE ANY PROCEDURE system
privilege may execute the package.
