QUESTION: Safest and most efficient way to reclaim bigfile tablespace space

in Storage Management (ASM ACFS DNFS ODM) (MOSC) 3 commentsAnswered

Hello,

Environment: Oracle 12.1.0.2 single instance database using ASM

Issue: Safest and most efficient way to reclaim bigfile tablespace space

I created a bigfile tablespace sourced from a diskgroup in where a single schema was created that is containing only regular heap tables.

4.5 terabytes of data were loaded into the tables of this schema. 

DB compression (compress for OLTP) was applied to the tables reducing the schema to 2.0 Terabytes.

There is now 2.5 TB of free space showing in the tablespace and only 300 Gig of space remaining in the associated diskgroup.

I need to create a new schema and load 2 TB into this schema into the same tablespace.

Howdy, Stranger!
