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

directory), contains the source code for this package’s
specification. This script is called by
catrep.sql, which must be run to install the advanced
replication packages. The wrapped SQL script

only the owner (SYS) and those with the EXECUTE ANY PROCEDURE system
privilege may execute the package.
