liboraInstaller.so: wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch)

Machine Info: SunOS XXX 5.10 Generic_142909-17 sun4u sparc SUNW,Sun-Fire-V440

I run it on Sun Fire which is 64 bit.

It is possible to turn on opatch debug by export  OPATCH_DEBUG=true, but it does not help.

Lets see java version:

/usr/bin/java -version

java version "1.5.0_24"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_24-b02)

Java HotSpot(TM) Server VM (build 1.5.0_24-b02, mixed mode)

/usr/bin/java -d64 

execve(): No such file or directory

Error trying to exec /usr/jdk/instances/jdk1.5.0/bin/sparcv9/java.

Check if file exists and permissions are set correctly.

Failed to start a 64-bit JVM process from a 32-bit JVM.

Verify all necessary J2SE components have been installed.

(Solaris SPARC 64-bit components must be installed after 32-bit components.)

So, I don't have 64-bit JVM. I remembered that I installed WebLogic Server for Solaris 

(32-bit JVM). That was my fault... They already have "Additional Platforms (For 64-bit JVM Support, See Note Above)". Will try to install wls/wls1034_generic.jar. Hope it helps.
