TCL Scripting

Hi,

We are currently using these to load balance the traffic for our Oracle Collaboration Suite. We require a scripted keepalive which will be pointed to a particular url, then redirected to another URL (picking up a cookie) each time it is redirected. When it finally reaches the login page it can pass a username and password, and be able to login successfully.

The problem we have is Oracle are adamant that the CSS's are capable of a scripted keepalive that will be able to do this. But having read some info of the cisco site I am under the impression the CSS will not be able to manipulate the data returned by the OCS. http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_configuration_guide_chapter09186a00800d6b3f.html)

Thank you in advance

Re: TCL Scripting

Indeed, this is too complex to do.

It would also require too much CPU.

You should try to keep your keepalive as simple as possible.

Re: TCL Scripting

Hi,

For in-depth keepalives like this, the best way I've seen it handled is for the application group to create an asp page that runs code to check the backend applications (oracle in your case) and if it receives the expected response to return a 200 response code. If not, return a non-200. Then with the CSS you can just use the http keepalive and point it to this status page on the web or app server.

This way the network group, whom usually don't care to manage in-depth application checking scripts, can keep the CSS config simple. Also, if the web/app group wants to take there server out of the pool, they can just alter the status page to return a non-200 while they update or change things without having to contact the networking group.
