32 or 64bit

[Juergen Nagel_1]

Hello,

How can I find out whether an executable or shared lib is 32bit or 64bit?
Thanks

Juergen

Many ways to do it.

chatr "file_name"
file "file_name"

hi,

e.g.
$ file oracle
oracle: ELF-64 executable object file - PA-RISC 2.0 (LP64)
$

however, in some cases, you may not get it too!
e.g.
$ file zip
zip: PA-RISC1.1 shared executable dynamically linked
$ chatr zip
zip:
shared executable
shared library dynamic path search:
SHLIB_PATH disabled second
embedded path disabled first Not Defined
shared library list:
dynamic /usr/lib/libc.2
shared library binding:
deferred
global hash table disabled
plabel caching disabled
global hash array size:1103
global hash array nbuckets:3
shared vtable support disabled
static branch prediction disabled
executable from stack: D (default)
kernel assisted branch prediction enabled
lazy swap allocation disabled
text segment locking disabled
data segment locking disabled
third quadrant private data space disabled
fourth quadrant private data space disabled
third quadrant global data space disabled
data page size: D (default)
instruction page size: D (default)
nulptr references enabled
shared library private mapping disabled
shared library text merging disabled

Yes you get it

PA-RISC1.1 means 32-bit

Hi ,

You can also see it in the enviroinmental parameter SHLIB_PATH just byt typing on the unix promt as echo $SHLIB_PATH. This parameter is set in .profile file of oracle.

if the SHLIB_PATH has been set as $ORACLE_HOME/lib it is 64-bit, if it is set as $ORACLE_HOME/lib32 , it is 32-bit
