edited Sep 15, 2016 5:00AM in Database Administration (MOSC) 26 commentsAnswered

Hello,

I have oracle 12.1.0.2(upgraded from 12.1.0.1) with bundle patch. 22310559 (12.1.0.2.160119)

I noticed export schema is slowest then before.

I have 2.66GHz, 32gb ram, windows server 2012r2

My memory parameters:

SQL> show parameter target;

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

archive_lag_target                   integer     0

db_big_table_cache_percent_target    string      0

db_flashback_retention_target        integer     1440

fast_start_io_target                 integer     0

fast_start_mttr_target               integer     0

memory_max_target                    big integer 21056M

memory_target                        big integer 21056M

parallel_servers_target              integer     384

pga_aggregate_target                 big integer 5000M

sga_target                           big integer 15040M

SQL>

How can i improve export performance or find what caused that issue?

Howdy, Stranger!
