•
that all parameters configured using the DBconfig and ClientServerInstall
installers were performed correctly, as described in the 5620 SAM Installation
and Upgrade Guide
•
that there is sufficient time for the server to validate the need for an activity check
•
configurations are correct to handle two redundant servers behind a firewall
Go to the install directory/nms/config directory or folder and locate the
nms-server.xml file to check that redundant database configuration values are set
correctly to allow the 5620 SAM server to communicate with the primary (active)
database and, in the case of a database failure, the standby database.
i Open the nms-server.xml key file using a text editor.
ii Verify the following:
•
To allow redundancy, ensure the redundancyEnabled parameter is set to
true.
•
To ensure proper communication of TCP messages from the server to the
database about failover and switchover messages, ensure that TCP port
9002 is available and open.
•
To allow manual switchovers between the active and standby databases
using the client GUI, ensure the allowSwitchOver parameter is set to yes.
•
To allow manual failovers between the active and standby databases using
the client GUI, ensure the allowFailOver parameter is set to yes.
•
To allow automatic failovers between the active and standby databases
using the client GUI, ensure the dbAutoFailOver parameter is set to yes.
•
To specify the number of database connection retries initiated by the server
before a failover to the standby database is performed, ensure the
dbConnectMaxRetries parameter is configured. The default is 100.
•
The database name, database username, standby database name,
standbyHost, and passwords match the settings configured during
installation, as described in the 5620 SAM Installation and Upgrade Guide.
Save the changes, if required, and close the file.
