Advanced users can use the replcheck tool to check and repair replication on Directory Server. We strongly recommend that you use this tool with the guidance of Sun Support. The tool collects valuable information that Sun Support can use during problem diagnosis and can repair several types of replication halt directly. This tool is located in the install-path/bin/support_tools/ directory.

When run in diagnosis mode, the replcheck tool diagnoses the cause of the replication breakage and summarizes the proposed repair actions. It compares the RUVs for each of the servers in your replication topology to determine if the masters are synchronized. If the search results show that all of the consumer replica in-memory RUVs are evolving on time or not evolving but equal to those on the supplier replicas, the tool will conclude that a replication halt is not occurring.
To diagnose a replication problem, run the replcheck tool as follows:
replcheck diagnose topology-file
The topology-file specifies the path to a file that contains one record for each line in the following format: hostname:port:suffix_dn[:label]. The optional label field provides a name that appears in any messages that are displayed or logged. If you do not specify a label, the hostname:port are used instead.
For example, the following topology file describes a replication topology consisting of two hosts:
host1:389:dc=example,dc=com:Paris host2:489:dc=example,dc=com:New York
If the replcheck diagnose command determines that a replication halt is occurring, then you can launch the replcheck fix subcommand to repair the replication halt. For example, the command determines that replication is blocked on the entry associated with CSN 24 if a supplier has a CSN of 40, while the consumer has a CSN of 23 that does not evolve at all over time.
To repair a replication halt, run the replcheck fix command as follows:
replcheck fix TOPOLOGY_FILE
