You can test your Apache resource hierarchy by initiating a manual switchover. This will simulate a failover of a resource instance from the primary server to the backup server.

Performing a Manual Switchover from the GUI

You can initiate a manual switchover from the LifeKeeper GUI by selecting Edit, then Resource, then finally InService from the drop down menu. For example, an in service request executed on a backup server causes the application hierarchy to be placed in service on the backup server and taken out of service on the primary server. At this point, the original backup server is now the primary server and original primary server has now become the backup server.

If you execute the Out of Service request, the application is taken out of service without bringing it in service on the other server.

Recovery Operations

When the primary server fails, the Apache Recovery Kit software performs the following tasks:

  • Brings Apache into service on the backup server by bringing in service the IP address(s) on one/more of that server’s physical network interfaces
  • Mounts the file system—if one is being used—on the shared disk on that server
  • Starts the daemon processes related to Apache

After recovery, Apache Web Server users may reconnect by clicking on the Reload/Refresh button of their browsers.
