Hi,
I know my answer could be too banal, but are you sure that
- version of oracle library is compatible with the platform you are compiling on ?

Could you give more details ?

In Metalink this is the only note i found:

Problem Description: ==================== You are trying to create your own shared library using Oracle's archived libraries. You believe Oracle's libraries were compiled with the +z compiler option. You would like to get the libraries compiled with the +Z option. Problem Explanation: ==================== The compiler options +z and +Z cause the compiler to generate position independent code (PIC) for use in building shared libraries. Normally, +z should be used to generate PIC; however, when certain limits are exceeded, +Z is required to generate PIC. Solution Description: ===================== The 7.1.6 shared library liboracle.sl was compiled with +z, not +Z. The +Z option is not needed in order for liboracle.sl to be used successfully. If you wish to create your own shared library using Oracle's archived libraries, then it is up to you to make sure the contents of the shared library conform to the limitations of +z. Other uses of the Oracle software in customer-created shared libraries are not supported, and we cannot recompile our libraries with +Z.
.

Usuallt exec format error means that you are using the wrong binaries or shared libraries...

Hello Filo,

Check in search for "Bad Magic" there are several previous posts. Perhaps one of them can help you.

HTH, Vicente.

Hi,

you must check the number of kernel bits in your kernerl

getconf KERNEL_BITS

and the version of oracle
readbale from the label.

oracle 9.x is only for 64bit HPUX.

Can you tell us
- your O.S.
- your version of Oracle
- what are trying to do ?

Massimo

Re: Bad Magic....

Filosofo — Mon, 09 Jun 2003 08:29:46 GMT

Hello,
the kernel bits version is 64 bits, oracle version is 9.2.0.3.
On the same serever there is also 8.1.7 64 bits oracle version.

I hope that you can help me.

Hi,

Just a quick point, the bad magic error usually indicates that you have installed and attempted to run a binary compiled on an uncompatible platform / or compiled for different hardware or in this case, maybe you have an existing library for an older application that is not compatible with the new one.

Hope this helps,

Thanks Charles
I said that on the server thare is also oracle 8.1.7 64 bits.....but we don't use this version now.....
Can this is a problem like said Charles?

Thanks

Hi,
if you are sure that the binaries are for your platform, may be you mixed up your shared linraries.

Check the environtmane tf the user that is tryin to execute the action. Are the path regarding the 9.x ionstallation always the first occurences..

thanks Massimo,
the path is ok.

Charles Harris — Mon, 09 Jun 2003 09:36:34 GMT

Hi,

Just another quick thought, ( I know very little about Oracle ) you mentioned that the PATH variable was ok, but does the .profile for the new Oracle install point to the default PATH as defined in the generic /etc/profile ? - alonge the same line, have you tried removing the PATH env and only putting in the new working / libs / oracle filesystems, including the usual bin /usr/bin etc ?

Finaly, you could try performing a full system backup, removing the old version of Oracle or move its associated lib dirs out of the way and then reinstalling the new product?

Hope you fix it!

Cheers,

Hi, just to track down the problem: could you post the output of the following command?

file /sv/gbcldv27/rel/server/lib/liboracle.sl
what /sv/gbcldv27/rel/server/lib/liboracle.sl

Re: Bad Magic....

Bill Hassell — Mon, 09 Jun 2003 09:46:07 GMT

Actually, the path that you should be concerned about is $SHLIB_PATH, not $PATH which is used to find executables. When you login normally, the contents of /etc/PATH will be assigned to $PATH. However, the same should happen with /etc/SHLIB_PATH and the variable SHLIB_PATH defined in your environment. Because you have two instances of Oracle, there are likely two separate shared library directories for each instance. You need to make sure that $SHLIB_PATH does not have any reference to the old version of Oracle *and* any Oracle environment variables point only to the current version o Oracle and related directories. Oracle variables are usually added to /etc/profile or local .profile files, or sourced from those profile files.

Hi,
i'm running out of shots....
latest ld and liner patch ?
Previusoly there was a thread in which there were the patch requirement for a oracle 9.

What version of O.S. is yours (uname -a output) ?

Re: Bad Magic....

Massimo Bianchi — Mon, 09 Jun 2003 11:50:52 GMT

Hi,
try with a find with the name of the library.
May be it is not in the SHLIB_PATH.

If it is.... then check with chatr to see if searching is properly enabled.

Massimo
