Home -> Community -> Mailing Lists -> Oracle-L -> quick question on decompressing a table...
We have a fact table that was mistakenly created with the compression
option.
Fortunately there is not (too) much data in the table as of yet.
The table is partitioned and have bitmap indexes on all the foreign keys.
Downtime isn't a huge deal...but minimizing it would be a positive thing.
The easiest way I can think of to correct this is the following:
Create table temp as select * from comp_table nologging;
Drop table comp_table;
Recreate table comp_table
Insert /*+ append */ into comp_table select * from temp_table;
Rebuild bitmaps
Regrant privileges.
...any faster/easier way to do this? ...any gotchas working with compressed tables (not sure how it would relate to this situation)?
...I'm no expert on table compression and as it stands now, r'ing tfm at this point isn't won't be worth any time savings. I'm mostly just (a little) curious.
Thanks for any suggestions
Chris
