If we want to switch Siemens VoMSXpress application from one machine to another it's use scswitch command. Be informed this configuration uses Sun Cluster technology, in other technology such as Veritas it should be different.
1- chris application should be stopped and when starting the framework should run as last application
(/opt/xpress/SxFramework/scripts/Sx.sh SxFrameWork stop|start)
2- check sun cluster status
scstat
The status of cluster, like which app or db on which cluster, online or offline
Node name Status
--------- ------
Cluster node: voms1 Online
Cluster node: voms2 Online
3- Stop appropriate resource group
scswitch -F -g [rg_sxfwapp|rg_sxfwdb] (-F make offline)
4- Change primary node
scswitch -z -D [appvol|dbvol] -h [voms2|voms1] (-z change primary node)
5- Make resource online
scswitch -Z -g [rg_sxfwapp|rg_sxfwdb] (-Z make resources online)
6- Start chris application as mentioned above
