I don't think you need ora_charset and NLS_LANG setting - one or the other will do. Also, be careful with ora_charset if you make more than one connection and expect to use different client charsets on each one as by default charsets are per environment and by default DBD::Oracle only creates one environment handle (see ora_envhp).

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
