LOG_ARCHIVE_MIN_SUCCEED_DEST defines the minimum number of destinations that must succeed in order for the online logfile to be available for reuse.
- If you are using the
LOG_ARCHIVE_DEST_n parameters and automatic archiving is enabled, the value of this parameter cannot exceed either of the following:
- The total number of destinations
- The number of enabled, valid destinations specified as MANDATORY plus the number of enabled, valid non-standby destinations specified as OPTIONAL
- If you are using
LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST and automatic archiving is enabled, a value of 1 specifies that the destination specified in LOG_ARCHIVE_DEST must succeed. A value of 2 specifies that the destinations specified in both parameters must succeed.
If the value of this parameter is less than the number of enabled, valid MANDATORY destinations, this parameter is ignored in favor of the MANDATORY destination count. If the value is more than the number of enabled, valid MANDATORY destinations, some of the enabled, valid OPTIONAL non-standby destinations are treated as MANDATORY.
You cannot set a value for this parameter dynamically if LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST are in use. However, you can switch dynamically from one system to the other using ALTER SYSTEM, as follows:
- Set
LOG_ARCHIVE_MIN_SUCCEED_DEST to 1.
- Set the value of
LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST to the null string.
- Set the desired number of destinations for the
LOG_ARCHIVE_DEST_n parameters.
- Reset
LOG_ARCHIVE_MIN_SUCCEED_DEST to the desired value.
