```
# /opt/FJSVclora/sbin/hvoradisable -a <userApplication>

Re-enter Password > ******  (Re-enter “oracle” for password.)
Finished
```
Restart monitoring the Oracle instance resources
Execute the following command to restart monitoring Oracle resources. In standby operation, execute it on the operating node. In scalable operation with Oracle RAC, execute it on all the cluster nodes. In single-node cluster operation, execute it on the one node.
```
# /opt/FJSVclora/sbin/hvoraenable -a <userApplication>
