Java Question

Joe Short — Wed, 05 Oct 2005 08:58:19 GMT

I have a client who's main production application requires Java 1.3 RTE (this is a People Soft product). They are now installing some third party storage software that requires the Java 1.4 RTE. I know they both install in separate subdirectories (/opt/java1.3, and /opt/java1.4)
My concern is that People Soft may still somehow be impacted by the introduction of the newer version. The client is sure that a newer version will crash the application, unless they can both coexist. I am just trying to be 100% sure of what I do next. I am about 95% sure that I am safe, but...

I would be very surprised if you had a problem.

Have you asked People Soft themselves rather than the client?

Unfortunately, I don't have access to them, or all of the info I need to ask, like what specific People Soft app, or it's version.
Like I said, I'm 95% sure it won't be an issue. But I'm not ready to gamble a client, or they're business on the other 5%

Joe,

You need to check that the People Soft apps set their own PATH to /opt/java1.3 and not use the default /etc/PATH. As long as that is true, you should see no ill effects at all.

I've just googled "people soft" and it came up with http://www.peoplesoft.com

At the bottom of the page there is a "contact us" link. My feeling is that a question along the lines of "Do any of your products have a problem with Java 1.4?" should produce a sympathetic and accurate response. I hope I'm right - good luck!

That's what I was thinking too. I'm just looking down all avenues.

Thanks.

This is a situation in which I wouldn't even trust whatever some vendor told me (be it PeopleSoft, Oracle, or Mickey Mouse) because it's very difficult to answer with certainty given the complexity of some applications. The real way to find out is via a Sandbox so that you can replicate the environment; of course it's expensive - both in time and resources - but for mission critical applications it's the only way to safely do it. If your client is demanding certainty then nothing else really comes close.

On our 11i systems, we have an average of about 8 installations of java at any one time. Most are bundled with 3party software andmost have the requirement of environment variables pointing to their own bundled JAVA tree.

I have never seen any 3rd party software that uses the Java that is installed in /opt/javaX.X. Even the OpenView products use their own bundled Java environments. Also, our global profiles are bever defined with path definitions pointing to any distribution of Java.
