By default, Oracle Database 11g Release 2 uses the large time zone file, timezone_11.dat. This file contains all the time zones defined in the database.
If you are using Oracle Database 11g Release 2, set the Replication Agent pdb_timezone_file parameter to the location of the timezone_11.dat file:
ra_config pdb_timezone_file, $ORACLE_HOME/oracore/zoneinfo/timezone_11.dat
