Distributing the Authentication Server Processes
You can run the Authentication Server on machines other than the primary
node, and you can run multiple copies of the Authentication Server. The main
reasons for doing this are performance and reliability.
•
If the primary node is running many processes and resources on the node
are scarce, you might get better performance if you move the
Authentication Server to a less busy machine.
•
If you are using the Oracle database server to authenticate clients, you can
improve performance if you move the Authentication Server to the same
machine as the database.
•
If you have only one Authentication Server and several clients are
requesting authentication, then the requests are queued up. You can
improve this bottleneck situation by running multiple copies of the
Authentication Server.
•
If you run running multiple copies of the Authentication Server on
different machines and one machine fails, clients can still access the
Authentication Servers that are running on other machines.
The services for the Authentication Server are ORAWEB_wrbasrv and
ORAWEB_wrbahsrv
. ORAWEB_wrbasrv is the Authentication Broker service,
and ORAWEB_wrbahsrv is the Authentication Provider service.
Installing the Authentication Server on Remote Nodes
To run the Authentication Server on a remote node, you run orainst on the
remote node. In orainst, select the multi-node option, then select “remote”, and
then select “WRB” when prompted on what to install on the remote node.
During installation of the WRB on the remote node, you need to provide the
name of the primary node. The name of this node appears in the registry entry
HKZY_LOCAL_MACHINE\Software\Oracle\OMN_ADDR
.
Unlike running cartridges on remote nodes, you do not need to list the names of
the remote nodes in the Web Application Server Manager.
Running the Authentication Server
To start up the processes for the Authentication Server:
owsctl start -p wrbasrv
owsctl start -p wrbahsrv
