SJSAS 7 & 8/9 on same system?
Hello,
We currently run AS7SE on a V240 running Solaris 9. We're looking at upgrading to a more modern version of AS (8SE or 9SE when it is available). However, I was once told that it is not possible to run both AS7 & AS8 on the same system concurrently. As we have multiple sites hosted on the same server, we cannot migrate them all at the same time. We would like to have both an AS7 and an AS8 installation installed side by side and gradually migrate sites to the new server.
So my question is, can I install both server versions on the same system? Are there any special steps needed to pull this off?
Thanks,
Bill

It is very much possible to have both Appserver 7 and Appserver 8 installations on the same machine. Let me give a little bit of background :
There are two types of Appserver installation bits namely package based and file based. (If you have installed Appserver 7 from the JES installer, then you have a package based installation.)
You CANNOT have package based Appserver 7 and Appserver 8 on the same machine. But you can have file based Appserver 7 and 8 installations on the same machine. Also if your current Appserver 7 is a package based install, then you can most definitely install the file based Appserver 8 on the same machine (under a different directory offcourse)
Hope that helps.

Vasanth,
Thank you very much for your reply.
I downloaded the JES2005Q4 distribution of AS8. After unzipping the file, I see that it is a Solaris package-based distribution. I looked at the JES installation guide, but I don't see instructions for a non-package-based install process.
Is it sufficient to install the packages with pkgadd but to specify the "-R" option to use a non-default root path, or did I just download the wrong installation package?
Thanks,
Bill
If you have access to sunsolve.sun.com, download the file based installation bits. Search for the relevant patch that you need and download the latest patch (these are actually full appserver installation bits)
119169: Solaris SPARC EE
119170: Solaris x86 EE
119171: Linux RHEL2.1 RHEL3.0 EE
119173: Solaris SPARC PE
119174: Solaris x86 PE
119175: Linux RHEL2.1 RHEL3.0 PE
119176: Windows 2000/XP PE

Vasanth,
I was able to download and install it, and it's working great!
On to my next question which I'm hoping you can help with.
Another reason why I stayed on AS7 for this long is that it was a full j2ee server and also included CGI support for our legacy applications. It appears as though CGI support is no longer included in AS8. I remember hearing about something called "a reverse proxy plug-in" that allowed a Web Server instance to run CGIs and such, and it would then delegate to the AS instance to run j2ee apps.
Is that plug-in still the solution to having to support both j2ee and CGI? If so, where can I find it, and where can I find documentation for how to configure it?
Thank you very much for any insights you can offer.
Bill
hi Bill,
The docs for configuring the load balancer plugin is located at
http://docs.sun.com/app/docs/doc/819-2555/6n4r9qo8c?a=view
All of your J2EE apps can reside on the Appserver and the loadbalancer plugin will take care of "routing" requests from the webserver to the appserver.
Hope that helps,
Vasanth
