Oracle 12c timestamps for datapump output file and console.

Starting on Oracle 12c you can set timestamps on for datapump (expdp and impdp) output file and console messages. With new LOGTIME option you can control timestamps printing. This option can have 4 different values (NONE, STATUS, LOGFILE, ALL).

NONE is default value. With it there is no additional timestamps in the output file or in the console. 

STATUS With this value timestamps are printed in the console but not in the output file.

LOGFILE With this value timestamps are printed in output file but not in the console. 

ALL With this value timestamps are printed in the output file and in the console.

Oracle 12c nologging for impdp

There is very useful new feature in Oracle 12c impdp which you can use to get rid of logging when you are doing import.

For example big bulk imports you might want to take logging of (both table and index) this way archivelog disk is not getting full and you can save some time.  You can do this with impdp "TRANSFORM=DISABLE_ARCHIVE_LOGGING:Y" option.

If you want you can also choose to remove only table or index logging:
only table data logging off during import:
TRANSFORM=DISABLE_ARCHIVE_LOGGING:Y:TABLE
only index data logging off during import:
TRANSFORM=DISABLE_ARCHIVE_LOGGING:Y:INDEX 

Default value for this parameter is TRANSFORM=DISABLE_ARCHIVE_LOGGING:N which is doing normal logging during import.
