We are looking to install an additional environment onto an existing server. I was just wondering if anyone can share their experiences concerning this. Is it best to have 2 instances of websphere / ihs or simply to add an addtional application server to the existing websphere instance. Any experiences / best practices are appreciated.

You will only need 1 Webshphere Instance with different servers or clusters and Virtual Hosts. The LAWIPC variable must also be different. That is how Lawson seperates Env's.

You only need one Websphere install. You'll need a new application server and webserver made with new ports assigned. You'll also need a new WAS home to put your http.conf files and directories in. As stated, you'll give it a new LAWIPC and the Lawson installer will make it's entries in the lawson.env file. You'll need a new LDAP (ADAM/Tivioli) with a new port number on it if it's on the same server.

Thanks for your unput, has anyone installed 2 instances of WebSphere and 2 instances of IHS on 1 machine. I was thinking that by doing this the 2 envrionments can become more sperated ..... Any thoughts are appreciated. Thanks

When doing our upgrade to 9.0.1 we had two instances of Websphere. It can be done you will just have to use different port numbers for each instance.

I have been running 2 copies of Websphere / LSF on the same machine since we migrated from env 8.03. Our test environment is not bound to LDAP and we have not experienced any resource or performance issues. Short of running a TEST machine, this setup allows for a good level of separation for patches and testing - especially with EMSS where there is only one copy of the code per environment.

Joe .... I think that is the route a want to take.
So you have 2 instances of WebSphere and 2 instances of IHS, on one machine ?
Can you tell me what aspects of the envrionments you are sharing, for example Perl, Java, etc ....

Thanks

We are a windows shop. There are 2 distinct websphere installations, one copy of IIS, JAVA, PERL, MKS. We have a DEV product line in the TEST ENV and TEST and PROD product lines in our PROD ENV which is bound to LDAP (using ADAM). We also have an additional Webshpere instance on our DMZ that allows for remote access via endpoint to our PROD ENV for EMSS users.

Thank all for all the helpful hints. I think I am going to go with 2 instances of WebSphere and 2 instances of IHS on the same server ...... and other hints and experiences are greatly appreciated.

I can see in the WebSphere configuration screens how to define another app server and applications.

How do you configure IHS? Do you define two virtual hosts inside one IHS instance, or do you need two copies of IHS installed? I would like to do it with only one copy of IHS if possible.

Thanks for any tips.
