SET_DISABLED Procedure

To disable or enable propagation of the deferred transaction queue from the current site to a specified destination site. If the disabled parameter is true, then the procedure disables propagation to the specified destination and future invocations of PUSH do not push the deferred remote procedure call (RPC) queue. SET_DISABLED eventually affects a session already pushing the queue to the specified destination, but does not affect sessions appending to the queue with DBMS_DEFER.

If the disabled parameter is false, then the procedure enables propagation to the specified destination and, although this does not push the queue, it permits future invocations of PUSH to push the queue to the specified destination. Whether the disabled parameter is true or false, a COMMIT is required for the setting to take effect in other sessions.

Syntax

DBMS_DEFER_SYS.SET_DISABLED (
   destination   IN   VARCHAR2,
   disabled      IN   BOOLEAN := true,
   catchup       IN   RAW := '00',
   override      IN   BOOLEAN := false);

Parameters

Table 14-28 SET_DISABLED Procedure Parameters

Parameter	Description
destination	The fully qualified database name of the node whose propagation status you want to change.
disabled	By default, this parameter disables propagation of the deferred transaction queue from your current site to the specified destination. Set this to `false` to enable propagation.
catchup	The extension identifier for adding new master sites to a master group without quiescing the master group. The new master site is the destination. Query the `DEFSCHEDULE` data dictionary view for the existing extension identifiers.
override	A `false` setting, the default, specifies that Oracle raises the `cantsetdisabled` exception if the `disabled` parameter is set to `false` and propagation was disabled internally by Oracle. A `true` setting specifies that Oracle ignores whether the disabled state was set internally for synchronization and always tries to set the state as specified by the `disabled` parameter. Note: Do not set this parameter unless directed to do so by Oracle Support Services.

Exceptions

Table 14-29 SET_DISABLED Procedure Exceptions

Exception	Description
NO_DATA_FOUND	No entry was found in the `DEFSCHEDULE` view for the specified `destination`.
cantsetdisabled	The disabled status for this site is set internally by Oracle for synchronization during adding a new master site to a master group without quiescing the master group. Ensure that adding a new master site without quiescing finished before invoking this procedure.
