database will be erased during the restore operation. A message will be logged to
the supplier servers’ log files indicating that reinitialization is required.If you are
restoring a database containing data received from a supplier server, then one of
two situations can occur:
• Change log entries have not yet expired on the supplier server.
If the supplier server change log has not expired since the database backup was
taken, then you can restore the local consumer and continue with normal
operations. This situation occurs only if the backup was taken within a period
of time that is shorter than the value you have set for the maximum change log
age attribute. This attribute is called
nsslapd-changelogmaxage
and can be
found in the
cn=changelog5,cn=config
entry. For more information about
this option, refer to the Netscape Directory Server Configuration, Command, and
File Reference.
Directory Server automatically detects the compatibility between the replica
and its change log. If a mismatch is detected, the server removes the old change
log file and creates a new, empty one.
• Change log entries have expired on the supplier server since the time of the
local backup.
If change log entries have expired, you need to initiate consumer
reinitialization. For more information on reinitializing consumers, refer to
“Initializing Consumers,” on page 313.
For information on managing replication, see “Managing Replication,” on
page 279.
Restoring the dse.ldif Configuration File
To restore the
dse.ldif
configuration file, stop the server, then use the procedure
outlined in “Restoring a Single Database,” on page 159 to copy the backup copy of
the
dse.ldif
file into your directory. Once you have copied the data, restart your
server.
The directory creates two backup copies of the
dse.ldif
file in the
serverRoot
/slapd-
serverID
/config
directory. The
dse.ldif.startOK
file records a
copy of the
dse.ldif
file at server start up. The
dse.ldif.bak
file contains a
backup of the most recent changes to the
dse.ldif
file. Copy the file with the most
recent changes to your directory.
