Creating Server Pools for Policy Managed
Database Configuration
NOTE: The procedure in this section must be performed before creating
the database.
The nodes in a cluster can be organized into a server pool for better resource
management.
Each server pool has the following properties:
• The minimum number of nodes that must be available in the server pool.
• The maximum number of nodes that can be available in the server pool.
• The relative priority of a server pool compared to the other server pools.
Perform the following steps to create the server pool:
1
Log in as Grid user.
2 Run the srvctl command from the grid home to see the default
configuration. For example:
[grid@node1 bin]$ ./srvctl config srvpool
3
Add a server pool by running the following command.
[grid@node1 bin]$./srvctl add srvpool -g fournodes
-l 2 -u 4 -i 2 -n node1, node2, node3, node4
where -g is the Server pool name, -l is the minimum number of nodes, -u is
the maximum number of nodes,
-i is the importance given to the server
pool,
-n is the node names which are part of the server pool. In this
example, the server pool name is
fournodes , the maximum number of
nodes are
four , the minimum number of nodes are two , the relative priority
of the server pool is
two , and names of nodes in the pool are node 1 , node 2 ,
node 3 , and node 4 .
4 Verify the server pool configuration by running the following command:
[grid@node1 bin]$./srvctl config srvpool
