32Bit or 64Bit

[Christian Marquardt_1]

Hi Guys,
is there any way to find out if a executable is a 32-Bit or 64-Bit executable?
We've an Oracle Agent installed and need to know whether this is 32-Bit or 64-Bit software.

regards
Christian

The "file" command shows what executable file it is : PA-RISC2.0 and ELF64 are 64-bit, PA-RISC1.1 and ELF32 are 32-bit if I am not mistaken.

Shalom Christian,

Find the binary.

what binary_name

Can give you a lot of information on the binary.

Hi all,
thanks for answering. I think my problem is that the emctl "binary" from the Oracle Agent 10g is a shell program which runs several java programs ...
Seems to be a bit difficult to me.

For a java program : look at the output of "ps -fxp "
Again if I am not mistaken :
java/IA64N, java/PA_RISC is 32-bit
java/IA64W, java/PA_RISC2.0W is 64-bit.

If it isn't obvious which executables are being run, you can use tusc -fp to follow the processes and then use file(1) as Wim said.

Any reason you care whether it is 32 or 64? If your kernel isn't 64 bit, you have other problems. ;-)

Hi all,
I think I've found it ... the Oracle agent is a perl program which uses the perl executable in the associated ORACLE_HOME.
And if I do this: file /opt/app/oracle/product/agent10g/perl/bin/perl I got this: /opt/app/oracle/product/agent10g/perl/bin/perl: PA-RISC2.0 ...
it seems to be 64-Bit executable.

thanks a lot @all!

/opt/app/oracle/product/agent10g/perl/bin/perl: PA-RISC2.0 ...
>it seems to be 64-Bit executable.

Unfortunately Wim's strings weren't the whole thing. It must be:
ELF-64 executable object file - PA-RISC 2.0 (LP64)
This is still 32 bit:
PA-RISC2.0 shared executable dynamically linked -not stripped
