Hi All,
In Oracle SuperCluster Environment we use important command ‘clrg’ for stopping and Starting of Oracle Web tier and Concurrent Manager Services.
clrg stands for clresourcegroup, which assist us to manage resource groups for Oracle Solaris Cluster data services or on Oracle SuperCluster Environment
Below are commands we use on Oracle Apps nodes as ‘root’ Operating system user on Solaris Environment where Oracle Supercluster is running:
In order to:
· Stop application on only application server 1 to stop all opmn and concurrent manager services on apps server1 and server2 completely.
# clrg offline opmn-rg
# clrg offline cm-rg
Start application on only application server 1:
# clrg online cm-rg
# clrg online opmn-rg
· Stop application on one application server (i.e Apps Server 1 or Apps Server 2):
# clrg offline –n nodename opmn-rg
# clrg offline –n nodename cm-rg
· Start application on one application servers (i.e Apps Server 1 or Apps Server 2):
# clrg online –n nodename cm-rg
# clrg online –n nodename opmn-rg
· Monitor the cluster resources
# clrg status
# clrs status
· Monitor the full cluster staus:
# cluster status
Example :
root@erpclusterapps1:~# cluster status
