Xclock ca resursa failover in SUN cluster

Asta e raspunsul pe care l-am dat unuia pe sunmanagers pentru a seta Xclock ca resursa in SUN cluster .... si cica i-a mers :-)

On any of the two nodes:

first you need to create the resorce type
the command to do this should look smth like this:

scdscreate -k -V SUN -T XCLOCK

Then you should create the resource package
the command to do this should look smth like this:

scdsconfig -s "/path_to_application_start_script" /
-t "/path_to_application_stop_script" /
-m "/path_to_application_monitor_script"
It's a goo idea to keep the rtconfig file (mv rtconfig SUNXCLOCK/ )
Now in SUNXCLOCK/pkg you should have got
a package for your resource

Install the obtained package on both nodes !!

pkgadd -d name_of_the_package

Register the resource in the cluster (to be done on only one node)

scrgadm -a -t SUN.XCLOCK

Create the resource group and then the resorce itself in the cluster (to be done on only one node):

scrgadm -a -g resorce-group-name

scrgadm -a -j resource-name -g resource-group-name -t SUN.XCLOCK

Activate the resource

scswitch -e -j resource-name

Good luck !!
