See COPYRIGHT/LICENSE. +.\" $OpenLDAP$ +.SH NAME +slapo\-syncprov \- Sync Provider overlay to slapd +.SH SYNOPSIS +ETCDIR/slapd.conf +.SH 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. +.SH CONFIGURATION +These +.B slapd.conf +options apply to the Sync Provider overlay. +They should appear after the +.B overlay +directive. +.TP +.B syncprov\-checkpoint <ops> <minutes> +After a write operation has succeeded, write the contextCSN to the underlying +database if +.B <ops> +write operations or more than +.B <minutes> +time have passed +since the last checkpoint. Checkpointing is disabled by default. +.TP +.B syncprov\-sessionlog <ops> +Configures an in-memory session log for recording information about write +operations made on the database. The +.B <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. +.TP +.B 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. +.TP +.B 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. +.SH FILES +.TP +ETCDIR/slapd.conf +default slapd configuration file +.SH SEE ALSO +.BR slapd.conf (5), +.BR slapd\-config (5), +.BR slapo\-accesslog (5). +OpenLDAP Administrator's Guide. +.SH ACKNOWLEDGEMENTS +.so ../Project |
