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.

Thanks
Andy

Not sure what you mean by maintain it in an automated way?



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.
