Procedure 7-4 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.
Procedure 7-5 To perform a 5620 SAM database switchover using the
5620 SAM client GUI
Perform this procedure to use the 5620 SAM client GUI to switch the primary and
standby database roles. Before you perform the procedure, ensure that you understand
the following implications of a switchover.
• The primary and standby database roles are reversed.
• The primary main server connects to the new primary database.
• Archive logging begins on the new primary database.
• The primary main server directs each auxiliary server to connect to the new
primary database.
1 Log in to the client GUI as a 5620 SAM user with the admin scope of command role.
2 Choose Administration→System Information from the 5620 SAM main menu. The
System Information form opens.
Caution — The execution of a database switchover depends on how
the database switchover behavior is configured. Alcatel-Lucent
recommends you review Procedure 7-4 before you attempt to perform
this procedure to verify the current database switchover configuration.
