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.

Property Description

Parameter type

Integer

Default value

1

Modifiable

ALTER SESSION, ALTER SYSTEM

Modifiable in a PDB

Yes

Range of values

1 to 10 if you are using LOG_ARCHIVE_DEST_n

1 or 2 if you are using LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST

Basic

No

If you are using the LOG_ARCHIVE_DEST_n parameters and automatic archiving is enabled, then the value of this parameter cannot exceed the number of enabled, valid destinations specified as MANDATORY plus the number of enabled, valid destinations that are configured with the OPTIONAL and LOCATION attributes.

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, then some of the enabled, valid destinations configured with the OPTIONAL and LOCATION attributes are treated as MANDATORY.

You can switch dynamically from using the older parameters to the LOG_ARCHIVE_DEST_n parameter using ALTER SYSTEM, as follows:

  1. Set LOG_ARCHIVE_MIN_SUCCEED_DEST to 1.

  2. Set the value of LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST to the null string.

  3. Set the desired number of destinations for the LOG_ARCHIVE_DEST_n parameters.

  4. Reset LOG_ARCHIVE_MIN_SUCCEED_DEST to the desired value.
