If you are performing a datapump export and you are returned following error for one or more tables, this means that probably a simultaneous partition maintenance operation is in progress during this time this table was accessed for export. ORA-31693, ORA-02354, ORA-02149
ORA-31693: Table data object "<TABLE_OWNER>."<TABLE_NAME>":"<PARTITION_NAME>" failed to load/unload and is being skipped due to error: ORA-02354: error in exporting/importing data ORA-02149: Specified partition does not exist |
If you are performing a SCN or time based recovery and RMAN-20208 is returned, It means that there was a SCN or time-based recovery previously done after which database was opened with reset logs, and now database has a new incarnation number. If you once again want to perform a recovery for any reason, or previously done incomplete recovery was not until the point where we wanted database to be, you need to reset the incarnation of the database and repeat the incomplete recovery process.
Starting 12c with the introduction of pluggable databases, we can perform point-in-time recovery either at CDB (container database) level or at individual pluggable databases level, in a multi-container CDB. CDB level recovery is same as conventional database point-in-time recovery that existed prior to 12c. In this document I will explain how to perform point-in-time recovery of a CDB (that could be a non-container database, or a multi-container database with one or more PDBs); and also, recovery of an individual PDB in a multi-container CDB database.
