REMOVE_CONFIGURATION Function

DBMS_DG.REMOVE_CONFIGURATION (
     preserve_destinations IN BOOLEAN DEFAULT FALSE,
     severity              OUT BINARY_INTEGER)
RETURN BINARY_INTEGER;

Parameters

Parameter	Description
preserve_destination	A boolean value to indicate whether the log_archive_dest initialization parameter setting should be preserved or clear when removing member from the configuration. A value of TRUE indicates that the parameter setting will not be cleared. A value of FALSE indicates the parameter setting will be cleared.
severity	The severity associated with the status returned by this function. Severity will be one of the following Oracle error numbers: ORA-0: normal, successful completion ORA-16501: The Oracle Data Guard broker operation failed. ORA-16502: The Oracle Data Guard broker operation succeeded with warnings.

Usage Notes

• This function returns a binary integer.

• When you remove a broker configuration, management of all the members associated with that configuration is disabled.
• By default, this function causes the corresponding broker settings of the LOG_ARCHIVE_DEST_n initialization parameter on the primary database and the LOG_ARCHIVE_CONFIG initialization parameters on all members of the configuration to be removed. To preserve these settings, specify a value of true for the preserve_destinations parameter.
• This command does not remove or affect the actual primary or standby database instances, databases, far sync instances, data files, control files, initialization parameter files, server parameter files, or log files of the underlying Oracle Data Guard configuration.
• You cannot remove the configuration when fast-start failover is enabled.

Return Values

Error	Description
ORA-00000: normal, successful completion	The configuration was successfully removed.
Other	The Data Guard broker was unable to remove the configuration and the return value will indicate the reason for this failure.
