Java installed is 32 bit or 64 bit

Syedfurquan — Tue, 29 Oct 2013 08:11:32 GMT

Hello,

I am using HP-UX 11.31 March 2013 on Itanium Blade 860C i2 server.

Now we are in the phase of installing Oracle Middleware and facing issues in installation. As per oracle support they are telling teh java installed is 32 bit.

How can I confirm teh version installed is 32 bit or 64bit? I checked older post and found out there is no separate JDK fro 32 bit and 64 bit but how can I confirm this.

Attaching soem o/p from server for reference.

# /opt/java6/bin/java -version

java version "1.6.0.16" Java(TM) SE Runtime Environment (build 1.6.0.16-jinteg_09_oct_2012_05_53-b00) Java HotSpot(TM) Server VM (build 20.9-b04-jre1.6.0.16-rc1, mixed mode) # #

Nothing to check, both 64 and 32 bit java are always installed.

If you want 64 bit, you must use -d64.

Thanks Dennis.

That's fine. I saw your earlier post and found same solution.

But if java is installed why it is giving error as jre installed is not found. Install java above 1.3 version.

Also application team is asking to install java with the application "user" who is going to install application. Is it possible.

Syed

Have you exported JAVA_HOME? What does the error look like?

You want to have another copy of java?

Hi Dennis,

I have not exported JAVA_HOME. How can I do that? The error we are getting at the time of application installation is after completing 92% it gives error something like not able to link java with application directory.

>You want to have another copy of java?

I tried installing Itanium_JDK_JRE7.0.0.7 and Itanium_JDK_6.0.20 but I installed both on default location with root user and it doesn't help me out.

Then we thought unistall weblogic and install it again so at the time of unistalling it fails giving error as jre not found in some directory path it is giving and then install jre 1.3 or above.

Regards,

Syed

Hello,

Can I install jdk with a specific user like dba?

The application team is asking to install jdk with the user installing the application. Please suggest.

export JAVA_HOME=/opt/java6

Or:

export JAVA_HOME=/opt/java7

>I installed both on default location with root user and it doesn't help me out.

Why not? If you install it and export JAVA_HOME, it should use that one.

>Can I install jdk with a specific user like dba?

No, SD installs must use root unless packaged with run_as_superuser=false.

JAVA_HOME should be set to "/opt/java" or "/opt/java7" .
