JVM Problems - Unable to initialize threads

Robin King_1 — Wed, 06 Jul 2005 06:19:52 GMT

We have two 'identical systems' running HP-UX 11.11. Once was ignited from the other. Both systems have Oracle installed.

The DBA's are trying to start a Java installtion app for Oracle on the second box, but are being given the following error:

Unable to initialize threads: cannot find class java/lang/Thread
Could not create Java VM

I've had a look round and this appears to be an issue with JAVA_HOME or something similar. I'm not sure how to resolve it though. I've compared $PATH for oracle user on both servers and they're identical.

I have seem to have three versions of Java running, 1.2, 1.4 and 1.5. I've tried exporting JAVA_HOME=/opt/java1.5 and /opt/java1.5/bin, but neither seem to resolve the problem.

I found an hp doc that suggested checking the Java Programmers guide, but that didn't really help.

Any help would be appreciated.

Thanks

Robin

Hi,
what happens if you try java-version command(whith oracle user) on both servers? Are there any differences?

Hope this helps

The versions are the same:

erbhap2:9.2.0:LNKT:/apps/oracle::/opt/java1.5/bin/java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-_24_nov_2004_16_29)
Java HotSpot(TM) Server VM (build 1.5.0 FCS (JS B64) jinteg:11.24.04-15:51 PA2.0 (aCC_AP), mixed mode)

However we seem to have three versions installed:

# ls /opt/java*

/opt/java1.2:
jre plugin

/opt/java1.4:
3D.release.notes LICENSE.Java3D include man
COPYRIGHT THIRDPARTYLICENSEREADME.txt java.os11.release.notes
COPYRIGHT.Java3D bin jre
LICENSE demo lib

/opt/java1.5:
COPYRIGHT bin java.os11.release.notes.html sample
LICENSE demo jre
THIRDPARTYLICENSEREADME.txt include lib

This problem is too fundamental to be worrying about patches.
That is your CLASSPATH set to?
What does your java command line look like?
Is there a bootclasspath?
Has rt.jar been edited?
