Hi Dunston,
the problem could the DBD::Oracle installation.
Do you have multiple Oracle installations on your box?
If not: you could reinstall DBI and DBD::Oracle and make sure that your
Oracle environment is set correctly. Are/Were there any errors during
the installation?
If you have multiple Oracle installations: set your $ENV{ORA_NLS10}
using the ORACLE_HOME with which you compiled your DBD::Oracle. Also try
ORA_NLS and ORA_NLS33 (if the installation is pre-Oracle 10) - but only
one of the ORA_NLS variables per test.
If you have multiple perl installations (with DBI, DBD::Oracle) you may
have to set the correct path to perl (first line of your script).
Next step might be tracing:
DBI->trace($trace_setting, $trace_filename)

Hi
Firstly, thanks for continuing to work with me on this. Here's my
script. and the output. I am able to connect to all databases from
the cygwin prompt, but am
unable to get the script to connect.
I have all the below-mentioned environment variables set in the
Windows environment as well, which cygwin picks up at start-up as well.
Regardless, I set them in the script as well, as shown below. I have
tried all variations of the DBI->connect statement mentioned in
the perldocs in the script below, but continue to encounter the
OCIEnvNlsCreate error.
It seems to be a permissions issue, but I don't know where to look.

Hello Dunston,
did you read
perldoc DBI
and
perldoc DBD::Oracle
? To detect if DBI is able to locate DBD::Oracle use:
@driver_names = DBI->available_drivers;
If so, you can idenitfy your oracle Instances via:
@data_sources = DBI->data_sources($driver_name, \%attr);
You may try:
use DBI;
print "available_drivers:\n";
print "$_\n" foreach DBI->available_drivers;
print "\ndata_sources:\n";
print "$_\n" foreach DBI->data_sources('Oracle');
The output of the latter may be used for the connect statement.

Hi
I have updated my system per your instructions and also included these lines as
a preamble in my test script.
I have modified the security settings for every folder under ORACLE_HOME to
give full read-write permissions to every user-account on this computer.
However I still continue to encounter the same error.
Any input on resolving the above would be helpful!
Thanks

Hello Dunston,
in my test script i set:
$ENV{ORACLE_SID} = "ORCL";
$ENV{ORACLE_HOME} = "/path/to/oracle/home";
$ENV{NLS_LANG} = "AMERICAN_AMERICA.WE8DEC";
# or "GERMAN_GERMANY.WE8ISO8859P15";
$ENV{ORA_NLS} = $ENV{ORACLE_HOME} . "/ocommon/nls/admin/data";
$ENV{PATH} = $ENV{ORACLE_HOME} . "/bin:/usr/bin";
$ENV{LD_LIBRARY_PATH} = $ENV{ORACLE_HOME} . "/lib";
In Oracle10 you should replace NLS_LANG by s'thing like:
$ENV{ORA_NLS10} = '/oracle/product/10.2.0/nls/data';

Hi
I had posted a few days ago about facing problems installing DBD::Oracle with
Oracle 10g client under Cygwin.
Though those were circumvented successfully, when I try to run a simple script that calls DBI->Connect, I get
DBI connect(....) failed: ERROR OCIEnvNlsCreate. Check ORACLE_HOME env var, NLS
settings, permissions, etc. at tmp.pl line 12
Error ERROR OCIEnvNlsCreate. Check ORACLE_HOME env var, NLS settings,

ORACLE_HOME C:\oracle\product\10.2.0\client_2
ORACLE_SID DEVDB

NLS_LANG WE8ISO8859P15
I saw some earlier threads on this issue which recommended ensuring that the permissions on ORACLE_HOME/bin and ORACLE_HOME/lib are set correctly.
All user-accounts on this machine have "Full Control" for these directories.
Any recommendations anyone?
Thanks
