Oracle db: 11.2.0.4.8

RAC:          4 nodes

OS:              Linux 6.6

DB size:      86TB

ASM

My plan is to restore 3 tables from a tape backup(a month ago) in a non-production server and have the following questions.

1. How much total space will I need in non-prod server?

2. What are the high level steps including syntax?

3. what is SGA/PGA requirement?

In Production database where subject tables + indexes resides:

Data  tablespace: DATAL - size 4 TB (table size is only 200GB)

Index Tablespace: IDXM - size 1 TB (index size is only 50 GB)

you may need the following info. to calculate the required space :

UNDO TS      = 400 GB each( 1.6 TB in all 4 RAC instances) - UNDOTBS_01, UNDOTBS_02, UNDOTBS_03, UNDOTBS_04

Howdy, Stranger!
