How do I view the NFM-P system redundancy status?

Steps
 
1 

View the Standby Server, Primary DB and Standby DB status indicators in the NFM-P client GUI task bar. Each indicator must display Up.

2 

Choose Administration→System Information. The System Information form opens.

3 

View the general redundancy information:

  • Domain Name—the NFM-P domain name specified at installation

  • Redundancy Enabled—selected if redundancy is enabled

  • Realignment Enabled—selected if automatic database realignment is enabled; displayed only if the NFM-P system is redundant

  • Auto Standby Re-instantiation Enabled

  • Realignment Status—Aligned or Not Aligned

4 

View the following information in the Primary Server panel:

  • Host Name—the host name of the primary or standalone main server

  • Preferred DB—the preferred database of the main server

  • Status—Unknown, Down, or Up

5 

View the following information in the Primary Database Server panel:

  • Instance Name—the name of the primary database instance, also called a SID

  • IP Address—the IP address that each main or auxiliary server uses to reach the primary database

  • Host Name—the host name of the primary or standalone main database

6 

If the NFM-P system is redundant, view the following information in the Standby Server panel:

  • Host Name—the host name of the standby main server

  • Status—Unknown, Down, or Up

7 

If the NFM-P system is redundant, view the following information in the Standby Database Server panel:

  • Instance Name—the name of the standby database instance, also called a SID

  • IP Address—the IP address that each main or auxiliary server uses to reach the standby database

  • Host Name—the host name of the standby database

8 

Click Properties to display additional information about the primary or standby main server. The Main Server (Edit) properties form opens.

9 

View the following general main-server information:

  • Host Name—the host name of the primary main server

  • Server Type—Main

  • Resource Managed—selected if the main server is included in NFM-P resource management

10 

View the following information in the Client Communication panel:

  • Private IP Address—the IP address that the main server uses as the source address for communication with the NFM-P GUI, browser, and XML API clients through a NAT router

  • Public IP Address—the IP address that the NFM-P GUI, browser, and XML API clients use to reach the main server through a NAT router

Note: The Private IP Address and Public IP Address display 0.0.0.0 when the NFM-P clients and the main server use host names, rather than IP addresses, for communication.

The Private IP Address and Public IP Address display the same IP address when NAT is not used between the main server and clients.

11 

View the following information in the Redundant Server Communication panel:

  • Private IP Address—the IP address that the main server uses as the source address for communication with the standby main server through a NAT router

  • Public IP Address—the IP address that the standby main server uses to reach the primary main server through a NAT router

  • Peer Public IP Address—the IP address that the standby main server uses to reach the main server

Note: The Private IP Address and Public IP Address display the same IP address when NAT is not used between the primary and standby main servers.

12 

View the following information in the Redundancy Database State panel:

  • Switchover State—whether switchover in progress, and operational state

  • Last Attempted Switchover Time—time of previous switchover attempt

  • Failover State—whether failover in progress, and operational state

  • Last Attempted Failover Time—time of previous failover attempt

  • Standby Re-instantiation State—whether reinstantiation is in progress, and operational state

  • Last Attempted Standby Re-instantiation Time—time of previous standby reinstantiation attempt

  • Number of Archive Logs To be Applied—number of archive logs that remain to be applied on standby database

  • Estimated Time to Apply Archive Logs (seconds)—system time estimate for archive-log synchronization with standby database

13 

View the following information in the Auxiliary Server Communication panel:

  • Private IP Address—the IP address that the main server uses as the source address for communication with the auxiliary servers through a NAT router

  • Public IP Address—the IP address that the auxiliary servers use to reach the primary main server

Note: The Private IP Address and Public IP Address display the same IP address when NAT is not used between the main server and the auxiliary servers.

14 

View the following information in the Main Server Communication panel:

  • Server Public IP Address—the IP address that the auxiliary server uses to communicate with the main server

15 

Close the Main Server properties form.

16 

Click Database to view detailed database information, if required.

17 

Click on the Faults tab to view alarm information, if required.

18 

Close the form.
