Normally, Oracle does not propagate the adding of datafiles on the primary database to the standby database. This must be done manually on the standby database. Dbvisit Standby will automatically add the datafile to the standby database. Dbvisit Standby version 6.0.26 and later, will attempt to generate a new name for a standby datafile, in case the primary name cannot be used due to different storage type (ASM and non ASM) or different database file structure between the primary and standby. There are some restrictions to adding automatically adding the datafiles to the standby database. |

Every time Dbvisit Standby runs on the primary, it takes a snapshot of primary datafile ids and names and saves it in the repository. It also detects if new data files have been added to the primary since the last run. If so Dbvisit Standby creates a new text file "datafiles_ORACLE_SID_DEST.txt" and ships it to the standby server to the location specified by parameter LOGDIR_DR, before proceeding with transferring redo logs.
