slapo-syncprov - Sync Provider overlay to slapd
Синопсис (Synopsis)
ETCDIR/slapd.conf
Описание (Description)
The Sync Provider overlay implements the provider-side support
for the LDAP Content Synchronization (RFC4533) as well as
syncrepl replication support. The overlay can be used with any
backend that maintains entryCSN and entryUUID attributes for its
entries. It also creates a contextCSN attribute in the root entry
of the database.
The contextCSN is updated for every write operation performed
against the database. To reduce database contention, the
contextCSN is only updated in memory. The value is written to the
database on server shutdown and read into memory on startup, and
maintained in memory thereafter. Checkpoints may be configured to
write the contextCSN into the underlying database to minimize
recovery time after an unclean shutdown.
On databases that support inequality indexing, it is mandatory to
set an eq index on the entryCSN attribute when using this
overlay.
Конфигурация (Configuration)
These slapd.conf
options apply to the Sync Provider overlay.
They should appear after the overlay
directive.
syncprov-checkpoint <ops> <minutes>
After a write operation has succeeded, write the
contextCSN to the underlying database if <ops>
write
operations or more than <minutes>
time have passed since
the last checkpoint. Checkpointing is disabled by default.
syncprov-sessionlog <ops>
Configures an in-memory session log for recording
information about write operations made on the database.
The <ops>
specifies the number of operations that are
recorded in the log. All write operations (except Adds)
are recorded in the log. When using the session log, it
is helpful to set an eq index on the entryUUID attribute
in the underlying database.
syncprov-sessionlog-source <dn>
Should not be set when syncprov-sessionlog is set and vice
versa.
When accesslog for this database is configured and is
logging at this suffix, it can be used as the session log
source instead of the in-memory session log mentioned
above. This log has the advantage of not starting afresh
every time the server is restarted.
syncprov-nopresent TRUE | FALSE
Specify that the Present phase of refreshing should be
skipped. This value should only be set TRUE for a syncprov
instance on top of a log database (such as one managed by
the accesslog overlay). The default is FALSE.
syncprov-reloadhint TRUE | FALSE
Specify that the overlay should honor the reloadHint flag
in the Sync Control. It must be set TRUE when using the
accesslog overlay for delta-based syncrepl replication
support. The default is FALSE.
