Sorry about that didn't see that one
Looking at this I can see your problem.
perhaps you can attempt a proxy type connection?
like though DBD::Gofer
You might get away with this with an 9 client and if memory serves me
correctly it can connect both wallet and the old 8 way
DBD::Oracle would then be able to handle both.

Please read the next post I put up to rephrase my question.
In all cases the connections have to 'external' - No name or password
given. The mechanism changed to the Oracle wallet in 10 for external
connections.

I would have to agree with martin.
your best bet would be to get 1.17 ~1.20 of DBD::Oracle and then find a
copy of the Oracle9 client It sould be able to connect to 8 and 10
without any problem

Probably a silly question, but why do you need two versions of
DBD::Oracle? Can't you build DBD::Oracle against an Oracle client
that is able to connect to both versions? I know the 9i client we
currently use will connect to both 9i and 11g DB instances. I'm
pretty sure a couple of years ago we had a version that would connect
to Oracle 7 and 9i.
May be a bit less hassle.

Hi all,
Hope someone can help.
I need to talk to both an oracle 8 and oracle 10 server in the same
script using their respective "external connections" capabilities (i.e.,
no user name or password -- system authentication on 8 & wallet on
10 ).
Hacked up a version of DBD to get everything renamed from 'Oracle' to
'Oracle8' and built against Oracle 8 libs. The other is built against
Oracle 10 libs. So I've 2 different builds in the same perl build:
./lib/site_perl/5.8.9/i686-linux/DBD/Oracle.pm
./lib/site_perl/5.8.9/i686-linux/DBD/Oracle8.pm
./lib/site_perl/5.8.9/i686-linux/auto/DBD/Oracle/Oracle.h
./lib/site_perl/5.8.9/i686-linux/auto/DBD/Oracle/Oracle.so
./lib/site_perl/5.8.9/i686-linux/auto/DBD/Oracle/Oracle.bs
./lib/site_perl/5.8.9/i686-linux/auto/DBD/Oracle8/Oracle8.so
./lib/site_perl/5.8.9/i686-linux/auto/DBD/Oracle8/Oracle8.bs
./lib/site_perl/5.8.9/i686-linux/auto/DBD/Oracle8/Oracle8.h
( Oracle.pm is oracle 10 & Oracle8.pm is oracle 8 )
I'm reading from a single tns_names.ora.
( SERV2 is Oracle 10 & SERV1 is Oracle 8 )
ORACLE_HOME is the same each time.
LD_LIBRARY_PATH includes 2 entries - 1 for Oracle 10 lib directory
and 1 for Oracle 8.
So the environment is the same every time.
I can:
--------------------------------------------
use DBD::Oracle8;
my $db3=DBI->connect("dbi:Oracle8:SERV1",'','');
--------------------------------------------
Or I can:
--------------------------------------------
use DBD::Oracle;
my $db3=DBI->connect("dbi:Oracle:SERV2",'','');
--------------------------------------------
but:
--------------------------------------------
use DBD::Oracle8;
use DBD::Oracle;
my $db3=DBI->connect("dbi:Oracle8:SERV1",'','');
my $db3=DBI->connect("dbi:Oracle:SERV2",'','');
--------------------------------------------
Will make both connections successfully, but exits
with a segmentation fault
Or if I reverse the connections:
--------------------------------------------
use DBD::Oracle8;
use DBD::Oracle;
my $db3=DBI->connect("dbi:Oracle:SERV2",'','');
my $db3=DBI->connect("dbi:Oracle8:SERV1",'','');
--------------------------------------------
first connection succeeds and second fails.
Also, these obviously fail because of wrong Oracle version:
--------------------------------------------
use DBD::Oracle;
my $db3=DBI->connect("dbi:Oracle:SERV1",'','');
--------------------------------------------
--------------------------------------------
use DBD::Oracle8;
my $db3=DBI->connect("dbi:Oracle8:SERV2",'','');
--------------------------------------------
Any ideas as to why? Thanks.

I'd hope someone else can come up with a different solution to your
problem but I'd be surprised if it worked as you have done it.
I'm assuming the DBD::Oracle8 is linked against a different set of
client libs to DBD::Oracle?
For a start, the 2 oracle client libs will export a lot of the same
symbols and so when you call oci_xxx where is it resolved - in the
oracle 8 client or the other one. To make this work you'd need the
dynamic linker to group the symbols and work down the group - I think it
/may/ be worth setting PERL_DL_NONLAZY and exporting it (or whatever it
is - run make test for DBD::Oracle and watch the output looking for the
xxxLAZY environment variable). If this works it pretty much proves it
but I'd still hope there is a better solution.
I think you have probably entered a world of pain.
