Performance Issue while Importing Tables

edited May 5, 2015 10:02AM in Database Administration (MOSC) 6 commentsAnswered

Hi All,

This is a query regarding the  best approach that should I follow whicle importing 150 GB of tables.  I have a single table which will result into oracle dump of 150 GB when using normal exp command.

I have to import it from one database to another.

Approach 1:  I am not very sure about how the normal imp command will impact the perfomance of Database & how much time (approx.) the import will take. (Both the Dump file & DB are on the same computer.)

Approach 2 : The source & target Database are  are physically at Different  location , can I  insert the data in this table, using insert statement  via DB link. Are there any chances of  timeouts?
