CMS R3V8 High Availability User Guide
Primary versus Secondary CMS servers 2-2
It is strongly recommended that no users are logged into the Secondary
CMS server while the Primary CMS server is operational. If the Primary
CMS server experiences a failure event, your ability to switch CMS users
over to the Secondary server will depend on your site-specific specific
switch-over strategy, as discussed in “
HA Server Switch-over After a
Failure Event” on page 1.
The benefit to creating and following a routine where you always perform
administration on the Primary CMS server and transfer (synchronize) the
data to the Secondary CMS server is that you will be more likely to
synchronize your data correctly.
CMS HA Server
Maintenance
2
To assure that both CMS servers are healthy and able to accept and
process data from the DEFINITY ECS, it is strongly recommended that
the administrator, on a daily basis, perform the following functions on
both CMS servers:
1. Verify that all links to both CMS servers are up.
2. Verify that archiving is occurring on both CMS servers. To do this,
select Maintenance > Archiving Status from the CMS
menu; press Enter to access the action list in the top right corner of
the Maintenance: Archiving Status window, then press
Enter again to view archive status information for all ACDs.
3. To verify that daily backups have run, select Maintenance >
Backup Data from the CMS menu; at the top of the
Maintenance: Backup Data window, output similar to the
following example is displayed:
Backups completed today: 1
Status: Last backup finished at 05/02/00 00:23:41
4. Check the customer error log on both CMS servers for unusual
errors.
Note that these maintenance procedures are not new or in any way
unique to the CMS High Availability offer. You are probably already
accustomed to performing these maintenance procedures on your
existing CMS server.
Failure to adhere to the maintenance practices listed above may
result in unnecessary loss of CMS data and/or incur additional
administrative charges associated with Lucent Technical Support.
