Minor Bugfix

Added

• add initialize all replication script 30_initialize_all.sh

Fixed

• Fix issue with wrong / missing ORACLE_SID on OUD environments
• fix issue where check of existing net service names does not work. Add bind
  parameter to function net_service_exists and fix scripts tns_modify.sh,
  tns_add.sh and tns_load.sh. If available they now check existing
  net service names with the corresponding bind values.
• Remove ORACLE_SID in tns_dump.sh
