Ers

[jyoti0306]

Hi all,

I have configured ERS in one system and tcServer in another and both are running fine. But, I am unable to point tcServer instances from ERS dynamically i.e. without bringing ERS down. How could I solve this problem?

Whether you use mod_jk or mod_proxy_balancer, you will need to restart ERS (Apache) in order to add new tcServers into the load balancing configuration. This means that in order to add new back end servers (be they tcServer or an other) you need to edit the httpsd.conf file, and restart the server.

Once you have the connections defined however, you can dynamically enable and disable the connections you have defined. Both JK and proxy balancer have HTTP interfaces which you can reach via browser to enable and disable the connections you have defined.

For proxy this interface is called "Balancer Manager".

See http://httpd.apache.org/docs/2.2/mod..._balancer.html

For JK this interface is called JK Status or JK Manager.

Hope this helps.
