RC 113 after fixing for LIBJVM.SO Not Found

Nalini · Post by **Nalini** » Wed Oct 05, 2005 10:36 am

Hello,

I am having a problem with getting an RC 113. I looked in the forum & it looks like it is a possible path, etc problem getting to the JVM. I have put in the explicit path & libpath statements as suggested before. But, still no luck. I am able to execute java -version under the OMVS shell when I use the explicit path.

One thing I had to do was that since I was getting an error for LIBJVM.SO not found because I did not have authority to access /etc/profile on this system, I put in some explicit export statements as per another forum entry.

Appreciate any suggestions on further ways to proceed.

Thanks,

Nalini -

There looks to be an error in your STDENV shell script:

02:48:43 JZOSVM14(E): child process exited with exit code 1

It looks like the problem might be the following line in your STDENV script:

. etc/profile

This is probably failing, causing the child shell process to exit with an error.
I think that your intention was to have this line commented out, correct?

Kirk Wolf

And I think that we might be able to improve the information that you get when it fails in this manner. Its not as clear as I would like; we'll see about improving it in the future. Thanks.

Thanks, that got me a little further!

Now, the task just seems to hang forever 'waiting for child'. I let this stay up for more than 2 hours and nothing ever happened. This is on a real z/OS system - not FLEX-ES. I recall that on FLEX-ES, startup can take quite a while!

It may be possible that I don't have some authority.

Thanks in advance for your help.

I'm not sure why it is hanging.

Can you log in to a unix shell using the same userid as running under the batch job? If so, try copying the STDENV input into an HFS file and execute it to see if it hangs or gets an error.

I think that we have seen this before, and it turned out to be a problem with the security setup for the batch userid.

I am finally getting back to this. A LOT of things came up last month - good to have so much activity, but..

Anyway, do you have some specifications on what authorities are needed for the batch user id so I can get that checked out first? I have a feeling that this may be something with forking a new task. Does that make any sense?

Thanks again for all your help.

Nalini,

If you can login to the userid from a regular telnet shell, then it should be fine. The configuration for a userid to use USS depends somewhat on the security package (RACF, ACF2, Top-Secret).

Here's a good reference for configuring and setting up USS under z/OS:

After fooling around for a while, I found this. The LIBPATH setting did not have a pointer to /java/lib.

The userid authorities did not make any difference. Hope this helps someone else!

Nalini -

Thanks for the information.

I think that you mean /usr/lib, not /java/lib, right? If so, that might explain why your shell process is hanging. I looked closer at your script, and I now notice that you aren't dotting in /etc/profile. If you don't do that, you should probably set at least the following:

PATH=/bin:/usr/bin:$JAVA_HOME/bin
LIBPATH=/lib:/usr/lib:$JAVA_HOME/bin:$JAVA_HOME/bin/classic
LANG=C
TC={as in /etc/profile}
NLSPATH={as in /etc/profile}

Sorry that I didn't notice this earlier.

Kirk Wolf
