Each table shows the status of the changes originated from a supplier replica.
Table Description
Table Header The table header shows the replica ID of
the supplier replica, the replica root, and the
maximum Change State Number (CSN) on the
supplier. The important thing is to make sure that
each supplier LDAP server has its unique replica
ID. Multiple replica roots on one LDAP server,
however, could share the same replica ID.
Table Row Each row represents a direct or indirect
consumer of the supplier (identified in the Table
Header).
Max CSN It is the most recent CSN the consumer has
replayed that was originated from the supplier
(identified in the Table Header).
Time Lag It shows the time difference between the supplier
and the consumer's max CSNs for the changes
originated from the supplier (identified in the
Table Header). A consumer is in sync with its
supplier when its time lag is
0
.
Last Modify Time It is roughly the time when the consumer's max
CSN was replayed.
Supplier This column lists all the suppliers of the
consumer.
Sent/Skipped Each supplier lists roughly how many changes
originated from the supplier (identified in the
Table Header) have been replayed or skipped
by the consumer. The numbers are kept in
suppliers' memory only. They will be cleared if
the supplier is restarted.
Update Status The number is the status code, and the string
is the implication of the status code. Watch this
column for possible deadlock if all the suppliers
complain that they cannot acquire the busy
replica. It is normal if one of the suppliers is
