LOGTIME is a new expdp/impdp parameter introduced in Oracle 12c. This prints the timestamp for each export operation during expdp backup. This helps to diagnose performance problems or elapsed time between each export operation. You can easily track or identify the time taken to export the specific object.
You have to add <LOGTIME=> parameter in expdp command. If you do not specify the LOGTIME option, then the default is <LOGTIME=NONE>.
Below are the values for LOGTIME parameter in expdp.
LOGTIME=NONE ---> This is the default value which will not display timestamp in both command window and export log file.
LOGTIME=ALL ---> This will display the timestamp in both command window and export log file.
LOGTIME=LOGFILE ---> This will display the timestamp in only export log file, not in command window.
LOGTIME=STATUS ---> This will display the timestamp in only command window, not in export log file.
#Execute below command with <LOGTIME=ALL> option. You can see the timestamp is displayed in both command window as well as in log file.
