If you deployed multiple IBM® WebSphere® proxy servers with
a cluster, you will need to configure additional ports for use with IBM Load Balancer so it can distribute
connections among the individual proxy servers. Configure the complete
set of ports for every WebSphere proxy
server used by the cluster.
Procedure
- On the WebSphere proxy
server, log in to the Integrated Solutions Console as
the WebSphere administrator.
- In the navigator, click .
- In the proxy servers table, click on the name of the server
that you want to configure.
- On the Configuration page, look under
"Communications" and click Ports.
- In the Ports table, create a non-secured SIP port as follows:
- Click New.
- Select User-defined Port.
- In the Specify Port Name field,
type PROXY_SIP_ADDRESS_LB.
- In the Host field, type the virtual
IP address that is configured as the cluster address on your load
balancer.
- In the Port field, type the non-secured
SIP port value (typically, 5060).
This value corresponds to the non-secured (TCP) port
through which the load balanced servers are configured to accept traffic.
- Click OK to save the new port
definition.
- Save the change to the master configuration by clicking
the Save link in the "Messages" box at the
beginning of the page.
- Now create a secure SIP port:
- Click New.
- Select User-defined Port.
- In the Specify Port Name field,
type PROXY_SIPS_ADDRESS_LB.
Notice
that this time, the port's name contains an "S" at the end of
"SIP" to indicate a secure port.
- In the Host field, type the virtual
IP address that is configured as the cluster address on your load
balancer.
- In the Port field, type the secure
SIP port value (typically, 5061).
This value corresponds to the secure (TLS) port through
which the load balanced servers are configured to accept traffic.
- Click OK to save the new port
definition.
- Save the change to the master configuration by clicking
the Save link in the "Messages" box at the
beginning of the page.
- Restart the WebSphere proxy
server.
- Repeat this task for every WebSphere proxy server that is used with
the cluster, making sure to specify the same port values on all of
the proxy servers (all proxy servers operating with a particular cluster
must use the same SIP ports).
