DBD doesn't work

itai weisman — Mon, 27 Feb 2006 03:38:02 GMT

hi people,
after succesfully installation of DBD for oracle,
progrmas won't work:
install_driver(Oracle) failed: Can't locate loadable object for module DBD::Oracle in @INC (@INC contains: /opt/perl/lib/5.8.
6/PA-RISC2.0 /opt/perl/lib/5.8.6 /opt/perl/lib/site_perl/5.8.6/PA-RISC2.0 /opt/perl/lib/site_perl/5.8.6 /opt/perl/lib/site_pe
rl .) at (eval 1) line 3
Compilation failed in require at (eval 1) line 3.
Perhaps a module that DBD::Oracle requires hasn't been fully installed
at ./cr_ts_esn_storage_pl line 55

i'm using perl 5.8.6 32bit with DBI 1.50, DBD Oracle 1.16, trying to connect to oracle 9i (Dbd has been compiled with oracle 32bit shared libraries)
thanks!

hi itai,

from the data you have provided it seems that DBD::Oracle has not been installed correctly, or the perl instance you are using to run you programs is not able to find it. this could be seen as install_driver() method is failing.

my suggestion would be to test first if DBD::Oracle driver is actually available for DBI - this can be done using DBI class methods: available_drivers(), installed_drivers () and installed_versions(). more info about their exact syntax can be found at: http://search.cpan.org/~timb/DBI-1.50/DBI.pm
if DBI is not able to list Oracle with installed_versions, it most probably means that something got wrong with installation, although it has been reported as successful. does the test suite passed?

check also if DBD/Oracle.pm is available in the directories listed in @INC, as this is the include path used by perl interpreter.

a good idea when troubleshooting perl would be to post the output of perl -V command.

because of many people has had problems with Perl + DBI on HP-UX a respected colleague of us - H.Merijn, has created a page hosting a precompiled versions of Perl + selected modules for HP-UX. you can take a look at it at: http://mirrors.develooper.com/hpux/downloads.html

hope this hels as an initial steps to further investigate the problem.

best regards,
marin

Re: DBD doesn't work

Matti_Kurkela — Mon, 27 Feb 2006 09:11:35 GMT

Have you set up the required environment variables?

The most essential ones are ORACLE_HOME and SHLIB_PATH, because DBD needs to use some libraries from the Oracle client installation.
The "Can't locace loadable object..." error message suggests that SHLIB_PATH might not be correct. The script /usr/local/bin/oraenv may help in setting these.

The ORACLE_SID and NLS_LANG are almost as important, and their correct values depend on the choices you have made.

Re: DBD doesn't work

itai weisman — Mon, 27 Feb 2006 09:50:27 GMT

during runtime or installation? I have configured these variables for installation... I have also set them before running the perl proggram

Re: DBD doesn't work

Alzhy — Mon, 27 Feb 2006 10:30:04 GMT

Shalom Itai,

You need to build DBD::Oracle on an environment that has a working Oracle installation.. you need to have the following defined:

# env|egrep "LD_|ORA|TNS|TWO"
ORACLE_BASE=/oracle/app/oracle
ORA_DUMP=/oracle/app/oracle/admin/dummy/bdump
ORACLE_SID=dummy
ORACLE_OWNER=oracle
TNS_ADMIN=/oracle/app/oracle/product/9.2.0.6/network/admin
ORACLE_TERM=xterm
LD_LIBRARY_PATH=/opt/cobol/lib:/oracle/app/oracle/product/9.2.0.6/lib:/usr/lib:/opt/hpws/apache/lib
ORACLE_HOME=/oracle/app/oracle/product/9.2.0.6
ORAENV_ASK=NO

Re: DBD doesn't work

Alzhy — Mon, 27 Feb 2006 10:32:25 GMT

And of course :

LD_PRELOAD=/oracle/app/oracle/product/9.2.0.6/JRE/lib/PA_RISC/native_threads/libjava.sl

Re: DBD doesn't work

H.Merijn Brand (procura — Mon, 27 Feb 2006 11:05:37 GMT

LD_PRELOAD should NOT be needed for DBD::Oracle

What's the output of this command?

Re: DBD doesn't work

Strange Procura, without LD_PRELOAD defined, I am unable to build DBD::Oracle on my custom built Perl 5.8.7 installation.

I got the tip from the accompanying README/INSTALL document that came with the Perl 5.8.7 source tree...

Re: DBD doesn't work

H.Merijn Brand (procura — Mon, 27 Feb 2006 11:58:41 GMT

If I look in README and README.hpux in the current development perl source tree, neither does refer to LD_PRELOAD.

INSTALL *does* mention LD_PRELOAD, but only for Linux.

The README.hpux.txt on DBD/Oracle-1.17 (which I' have just recently updated completely) *does* mention this variable in the context you say, but IMHO it should not be the preferred solution to these kind of problems.

use $HLIB_PATH and/or $LD_LIBRARY_PATH, as these are both supported on all HP-UX versions as of 11.00. (HP-UX 10.20 does not support LD_LIBRARY_PATH, but only supports SHLIB_PATH).

perl -MDynaLoader -MDBD::Oracle -wle'system qq{chatr $_} for grep/Oracle/,@DynaLoader::dl_shared_objects'

Show us the output please.

[ don't forget to think about the points once you have your solution ]

For Oracle9 I miss libqsmashr.sl in that list. Weird.
What does

ldd /opt/perl/lib/site_perl/5.8.6/PA-RISC2.0/auto/DBD/Oracle/Oracle.sl

show you?

Anyway, the shared object *IS* found, but cannot be loaded for some less obvious reason.

Re: DBD doesn't work

itai weisman — Tue, 28 Feb 2006 02:17:51 GMT

did you mean ld ? (and not ldd)
ld shows no output...

Re: DBD doesn't work

H.Merijn Brand (procura — Tue, 28 Feb 2006 02:44:23 GMT

No, I mean ldd.

ldd - print shared library dependencies

maybe the ldd you have also supports -v

ldd -v shared_object.sl

Itai,

Peace and Clean Air.

If you want, I can share with you our custom build of Perl 5.8.7 with the latest DBI and DBD::Oracle (comiples against Oracle 9.X..).

It installs in /usr/local/perl5.8.7 so it maintains your existing perl installed trees. It just completed intensive testing. It was compiled using HP aCC C.37 under HP-UX 11.11.

Let me know if want and provide me with a temp. FTP site. (the binaries are around 40MB).
