JDK on HP-UX 11i 64 or 32 bit?

[John Argo]

Is there any way to verify the that JDK or JRE installed on my system supports 64-bit? I have JDK 1.3 installed on a K-class running HP-UX 11i. I have java failures that suggest it is hitting limits imposed by 32-bit kernel settings instead of 64-bit.

[Denver Osborn]

Is your OS 32 or 64bit?

verify with:

# getconf KERNEL_BITS

[Michael Tully]

# getconf KERNEL_BITS /opt/java1.3/bin/PA_RISC2.0/native_threads/java
64

[John Argo]

getconf returns 64.

If you are using /opt/java1.2/bin/PA_RISC2.0/native_threads, then it will access 64-bit java.

Your getconf only tells you what the kernel mode is. Not really the java version.

Get the right version based on the app that actually needs java

Get and install the appropriate patches prior to installing java

Try again. It might work better

The java 1.4 releases include support for a -d64 option to get 64 bit addresses. You will need new 64-bit versions of any JNI libraries that you use. There are details in the release notes-

You could also look at this document about getting more memory space from a 32-bit java such as the java 1.3 releases.
