On our development database,
data part - 9 GB
index part - 13 GB.
Its not logical that index part is larger than data part.
So If i will do rebuilding the indexes whether it will increase space.
Suppose at the start i rebuild index of 1 GB ,does it make any issue?
because as per my knowledge rebuilding indexes requires free space.
And free space :
In data tablepace:5 GB
In index tablespace : 5 GB.

Let me know your comment on it as soon as possible.
Thanks in advance.
