Hi
[Quoted] We are looking for software that will help us to mange and monitor the snapshot synchronization process between deferent sites ( Slave/Master) We Need a GUI tool to monitor all the steps of the refreshing the slaves.
Some short descreption of the process :
snapshot in Oracle is kind of a replica of a target master table(or several
tables) from a single point in time.
Whereas in multimaster replication tables are continuously being updated by
other master
sites, snapshots are updated from one or more master tables through
individual batch updates,
known as a refreshes, from a single master site.
When a snapshot is refreshed, Oracle must examine all of the changes to the
master
table to see if any apply to the snapshot. Therefore, if any changes where
made to
the master table since the last refresh, a snapshot refresh will take some
time, even if
the refresh does not apply any changes to the snapshot. If, however, no
changes at
all were made to the master table since the last refresh of a snapshot, the
snapshot
refresh should be very quick.
Thanks
