Performance test in DEV with little data applying STATS from PROD

edited Aug 13, 2021 12:03AM in Database - RAC/Scalability (MOSC) 5 commentsAnswered ✓

Migrating database from 12.2 to 19c.

Our environment:

PROD RAC: 3 nodes - OS: OLE 7

  1. Our production is huge (110 TB)
  2. many Partition tables (2,000 + partition per some tables) + indexes

DEV RAC: 2 nodes - OS: OLE 7 - DB Size: 3 TB

  1. Our development DB is very small (3 TB)
  2. Not all schemas and all tables, we may have one or two weeks of data the most with 7-15 partitions.

We would like run some performance tests in our DEV(19c) environment but it is very small compared to prod. Someone suggested that we should apply Table/Index stats from prod to dev tables.

Q1. How would I do this ?
