I'll probably explain it with a piece of code and output, so everybody can
explain the problem I face clearly.
If you look at 2 codes, the only change is I modified 8i client with 10g
client. After that it couldn’t resolve the TNS connection string.
_Perl code with 8i client - works:_
#!/usr/local/bin/perl
#use DBI
#use strict;
use strict;
use lib '/u01/home/oracle/admin/site/lib/perl';
use DBI;
$ENV{ORACLE_HOME} = '/u01/home/oracle/product/8.1.7.4';
$ENV{TNS_ADMIN} = '/home/httpd/cgi-bin/oradba';
my $sid = "ECLD.WORLD";
my $usr = "mania2";
my $pas = "blah";
my $dbh = DBI->connect("dbi:Oracle:tns:$sid", $usr, $pas) or die $DBI::errstr;
Output:
bash-2.03$ ./perl_testing1.pl
DBI->connect(tns:ECLD.WORLD) failed: ORA-01017: invalid username/password;
logon denied (DBD: login failed) at ./perl_testing1.pl line 14

ORACLE_HOME not defined correctly?
(I would test by printing out all ENV from within script)

Instead of @<tns_string>, we define the connection string in TWO_TASK, and it
still looks for tnsnames.ora or sqlnet.ora for resolution and it fails.

All were done earlier. The problem is perl doesn't recognize my sqlnet.ora or
tnsnames.ora, though I define TNS_ADMIN correctly in the script.
Note: This was working when we used Oracle 8 client.

** This mail has been sent from an external source **
Hi,
We have a perl script which is used to connect to all our target databases ( close to 1000) and fetch the user related information and inturn
compare it with our enterprise directory which is used to clear the inactive users periodically. This was a very old script and it was using Oracle
8i client. Since most of our systems were upgraded to 12c, 8i client is not compatible with 12c - so we had to update the perl script to use 10g
client instead. After we did that, we are not able to connect to any databases and getting below errors. The script exclusively sets TNS_ADMIN to
point to right sqlnet.ora.
Need your help to fix this.
ORA-12154: TNS:could not resolve the connect identifier specified (DBD: login
failed)
