DBMS_REPCAT.ALTER_MASTER_PROPAGATION

Synopsis

The ALTER_MASTER_PROPAGATION procedure changes the propagation mode between specified master sites (from synchronous to asynchronous, or vice versa).

PROCEDURE DBMS_REPCAT.ALTER_MASTER_PROPAGATION
   (gname IN VARCHAR2,
    master IN VARCHAR2,
   {dblink_table IN dbms_utility.dblink_array | dblink_list IN VARCHAR2},
    propagation_modee IN VARCHAR2 := 'ASYNCHRONOUS',
    comment IN VARCHAR2 := '');

ALTER_MASTER_PROPAGATION does not automatically generate replication support triggers. After altering the propagation method, you must call GENERATE_REPLICATION_TRIGGER for replicated table in the replication group.

Parameters

Parameter Name	Description
gname	Name of the replication group whose propagation mode is being altered
master	Global name of the master site having its propagation mode altered
dblink_list	List of database links for which the master’s propagation mode is being altered
propagation_mode	New propagation mode (SYNCHRONOUS or ASYNCHRONOUS)
comment	Comment visible in DBA_REPPROP data dictionary view

Exceptions

Exception Name	Number	Description
nonmaster	–23312	One of the sites in dblink_list is not a master site.
nonmasterdef	–23312	Calling site is not the master definition site.
notquiesced	–23310	Replication group gname is not quiesced.
typefailure	–23319	The propagation_mode is not SYNCHRONOUS or ASYNCHRONOUS.

Restrictions

• You must run this procedure from the master definition site.

• The replication group must be quiesced.
