Make log shipping to work without copying password file from primary to physical standby when changing sys password on primary? Sometimes in a dataguard configuration the user SYS must be changing because of security policies. This results in a failed redolog shiping problem as describe by Harald van Breederode " Password file maintenance in a Data Guard environment " In this blogpost Harald was also mentioning redo transport authentication by an other Oracle user then SYS. To use an other Oracle user then SYS for redo transport authentication you have to do the following steps: In Oracle 11gR1 Oracle has introduced an new init.ora parameter called REDO_TRANSPORT_USER,  with this parameter Oracle can activate the redo transport authentication to be done by an other user then the default  user SYS.

External tables exists since Oracle version 9i, enable to view a file as if it were data in a database. To simplyfy the Extract, Transform, and Load (ETL) processes oracle had added a parameter  PREPROCCESS   to sqlloader for extrations by external tables. The  PREPROCESSING    parameter is introduced in Oracle version 11Gr2 which allow ETL processes handle any type of file without additional out-of-line action. (For example execute a shell script, unzip).
