Re: LD_PRELOAD problem

Hi Rich

The database is 9.2.0.7 64 bit HP-UX 11.11.

The batch process basically does this

---
export LD_PRELOAD=/sbl/xxx.sl

sqlplus /nolog << ! > /dev/null
@yyyy.sql
!

execute some application specific program
--

This worked in 8i but in 9i when sqlplus is executed we get the magic number
error. I understand that in 8i 32bit library was located in $ORACLE_HOME/lib
and 64bit in $ORACLE_HOME/lib64, in 9i this has been reversed,
$ORACLE_HOME/lib32 32 bit and 64 bit $ORACLE_HOME/lib. This is the only
change I can think about with 32 bit <-> 64 bit issue.

However when I unset LD_PRELOAD sqlplus works but of course the application
specific program fails.

Do you think if this can be corrected byI recompiling xxx.sl ?

Thanks

 Looks like you have a 32bit<->64bit issue.  Your Oracle DB install is
using one and you are attempting to use the other for your libraries.  Make
sure both are 32bit OR 64bit, but don't mix them.

HTH!  Enjoy!

 Hi

I was wondering what does LD_PRELOAD do in HP-UX? I understand more or
less that it loads some specific shared library with dld.sl before
searching SHLIB_PATH, am I correct?

The problem I am having is some batch processes which worked in Oracle 8i
after migrated to 9i they are giving this error:

/usr/lib/pa20_64/dld.sl: xxxxx.sl is not a valid load module: Bad magic
number

These batch processes export LD_PRELOAD variable with some customized
library, after exporting the variable all executables such as sqlplus,
exp/imp gives the error when are executed.

SHLIB_PATH is already set to $ORACLE_HOME/lib32

Thanks
