Perl Connect error after Oracle Upgrade

Hi All -

Oracle DB upgraded from 817 to 920 :

Perl Program connecting to DB fails which worked fine before with :

DBI connect('db','sch',...) failed: ERROR OCIEnvInit at /opt1/app/tb/lib/perl/DL-db-lib.pl line 89.

Did you have to re-install DBD also after Oracle upgrade ?

TIA,
Ravi
