expdp perfomance - improvement

edited Mar 27, 2017 9:28AM in Database Utilities (MOSC) 9 commentsAnswered ✓

Oracle DB: 11.2.0.4.8 - non-RAC

OS: Linux 6

DB size: 7.5 TB

Object type: Many daily / monthly partitions

This is 24x7 database.

1. How could I speed up expdp of production schema beside from using parallel degree?

2. Which parameter to use?

note: We do have some LOB data type in our database.

4. How could put the DB in read only during expdp, so data does not change in the database?

3. I will be importing into new server.

Parfile:

DIRECTORY= prxprod_dp

LOGFILE=expdp_prxprod_schema.log

PARALLEL=8

FILESIZE=10g

SCHEMAS = prxprod,hspprod

thank you.

Howdy, Stranger!
