Home -> Community -> Mailing Lists -> Oracle-L -> Initial Extent 5GB?? for 17GB table!!
Hi Friends,
Hi Friends,
I have GL table ready to reorg! The table underwent so many purges, Now had real data 17Gb with initial and next extents as 360M, Offcourse the total size showing 26Gb from dba_segments. I want to avoid export and Import process due to time taking.
I want to use CTAS to reorg this GL table.
First Create a copy of GL in Newtablespace
Drop main GL table
Creat New GL table with new storage parameters like Initial extent 5GB(I
knew I had more than 10Gb data!!) and next extent 360M, and pctused 40,
pctfree 5.
Insert data from copy GL to Main GL and create all indexes
My doubts are Can I create such a big Initial extent?? What other
implications I may face in future? Will it increase performance?? I can't
create newtablespace for this table due to my system already saturated in
terms of diskspace.
My environment is oracle7.3 on AIX, btw my avg row length is 448 bytes. MY
aim is simple! To pack the data and get back space!!
Thanks in advance for your help
peter.
