Hi,

on last weekend I upgrade schema from 10g data base to 11g database through datapump. Before I do upgrade I got recommendation from senior DBA to follow below step. Now we are stats facing database slow ness wile accessing data for all select /insert/update and delete operation. Here I am suspecting 

Do we need to import stats from 10g to 11g.

1.       Take backup/export of production MDH schema (CIMSOS) along with statistics.

2.       Refresh/import the schema into performance MDH schema (CIMSOS) with export from step #1 without statistics.

3.       Validate all the objects for no error and match count.

4.       Collect  fresh stats for entire MDH schema

Howdy, Stranger!
