in reply to Re^3: Install Oracle DBI DBD
in thread Install Oracle DBI DBD

I didn't need to revert back to an older version of ActivePerl. Here is the solution to this problem:

The PERL5LIB was one oracle which uses 5.8.3 sets up. So I made sure PER5LIB was changed to PERL5LIB=C:\perl\lib;C:\Perl\lib\DBD\Oracle;C:\Perl\lib\auto\DBD\Oracle;

Don't forget to reset the env variable or reboot.
