8 — 5620 SAM system redundancy
8-22 Alcatel-Lucent 5620 Service Aware Manager
5620 SAM
System Administrator Guide
• After a server activity switch, the new primary main server deploys
outstanding configuration changes to NEs, establishes communication with the
auxiliary servers, and synchronizes information with the auxiliary servers.
• A manual activity switch stops and starts the former primary main server.
Server redundancy is unavailable until the former primary main server is fully
initialized as the new standby main server.
1 Log in to the primary main server station as the samadmin user.
2 Open a console window.
3 Enter the following at the CLI prompt:
bash$ /opt/5620sam/server/nms/bin/nmsserver.bash force_restart ↵
The server activity switch begins. The primary main server restarts as the standby
main server, and the former standby main server becomes the new primary main
server.
4 Close the console window.
5 Clear alarms, as required. The activity switch alarms must be cleared manually.
6 Verify that the GUI and OSS clients can connect to the new primary main server.
Procedure 8-4 To configure 5620 SAM database switchover behavior
Perform this procedure on a redundant 5620 SAM system to specify how database
switchovers are executed. A database switchover occurs immediately upon request
unless a database query is in progress, in which case the 5620 SAM does the following:
• if session interruption is enabled, waits a specified period before forcing the
switchover
• if session interruption is disabled, the switchover does not occur and the
Switchover State is Failed
1 Choose Administration→Database from the 5620 SAM main menu. The Database
Manager (Edit) form opens.
2 Configure the required parameters:
• DB Session wait time (minutes)
• Interrupt Read sessions after time out
• Interrupt Write sessions after time out
3 Save your changes and close the form.
