Verifying Server Synchronization 27
If the databases are not synchronized, you see a list of the records that
are different.
The synchronization of the Primary and Secondary servers is a real-time
activity. The tblcmp utility gives accurate results only on an idle system
(one that is not processing telephone calls).
To re-synchronize the databases:
1 On the active server, at the command line enter this command:
xattach app
2 In the screen that appears, click Scripts/Spawn vssu_sync.
3 In the blue Tables window that appears, click the SS button to select all
the tables that are synchronized with Intelligent Mirroring.
4 Page down until you see checked boxes that indicate that the associated
tables are selected for synchronization.
5 Click the UD button to synchronize the selected tables.
The standby server is updated and restarted.
File System To verify that the file systems are synchronized, follow the procedures in
this section.
At the command line on both the Primary and Secondary Servers:
1 Enter this command:
diffmsg
If there are many files on the system, the diffmsg utility may take some
time to complete operation.
When the diffmsg utility stops, the system displays these two file counts:
■ Files to copy: — The number of files that exist on the other server
but do not exist on the local server.
■ Files to remove: — The number of files that exist on the local server
but do not exist on the other server.
If the value of files to copy is 0 (zero), then the file system is synchronized
from the perspective of the local server.
2 If the value of files to copy is not 0 (zero), then enter the command:
diff2rcp
