Re: Java Support question
Thanks for responding Mark - When I meant automated we do an RSU monthly and pick up any maint IBM puts out and since its part of my target we only pick up the latest version not all the versions. But I also see from you an others its NOT unusual in z/OS to have multiple versions available to your customers/users. This was the part that was throwing us off for example we always tell people using Cobol always use the LE version etc. Unfortunately JAVA isnt covered under LE and hard to enforce. It looks like for the one offs like EKM, WEBSPHERE we will just have to have multiple versions and decide do we just check the web from time to time for updates and download them or have multiple zones.

Originally we used SMP/E to install Java. But since each update is a complete replacement, we really found no benefit. When a new version was needed, the requirement came from the WebSphere group and they always requested the updates by names like 1.4.2 SR5. > >Now here is the real life challenge.

But if you want, you can create different target zones for each release... but we need different levels of the same release so that just doesn't work (see above). Since you are "told to install a specific version" (as we are), then that is what prompts you to get something new. Or you can just look periodically at IBM's web site: http://www-03.ibm.com/servers/eserver/zseries/software/java/ Here is what we do. We support a system level default Java. The level is at the lowest common denominator (example: 1.4.2 31-bit). It gets mounted at the default mount point of /usr/lpp/JAVA. We put JAVA_HOME and other environment vars in /etc/profile to point to the default. This is usually good enough for the majority of our Java users. The "OS" team supports the default version. We used to support all of the versions, but since WebSphere drove most of the requirements, they started installing and maintaining their own versions. For WebSphere, they have their own environment variables and point at a static local directory where we install z/OS UNIX software. In production and QA, that directory is a symlink pointing to where they have the desired version of Java. That way, they just update the symlink to swap new levels in. Our WebSphere development LPAR often has 3 or 4 different levels of Java mounted. That same directory structure is used for all the other levels / flavors of Java as well. They get pointed to via environment variables in the process(es) that invokes them if they don't want the default. For example, we are installing a product that required 1.4.2 SR7 (IIRC). That application runs in batch and while it could use BPXBTCH, JZOS was preferred and is being used. JZOS gives you a convenient way to specify the environment variables to point to the right level of Java. Another product being tested needed V5 64-bit.

Java Support question
I am trying to find out from anyone out there running z/OS and supporting Java. We have multiple programming areas that are requesting we put up a very specific version of Java or SDK. Let me be specific we have installed a ddef SAJV15D which has a path of /service/tgta/usr/lpp/java/J5.0_64/IBM/ and we have multiple versions of java installed. Now here is the real life challenge. We are installing IBM's EDK (for data encryption key store) they have a very specific JDK/SDK . We can easily copy it to its own directory but how does one maintain it in an automated way? Now the question is when your told to install a specific version, we run RSU monthly etc but if it doesn't know about it in the SMP/E zone how do you do it?
