ORA-01652: unable to extend temp segment

Roger,

The temporary segment you are seeing will become the index once the
statement has been completed.

I suspect you are running out of space because you are running the
operation in parallel. When you do this each parallel thread creates its
own extents so if, for example, the initial extent of the index is 6Gb
by specifying the degree of parallelism as 3 you automatically require
18Gb while the index is being built. Once the parallel slaves have
completed these temporary index segments are then coalesced down to give
an index of the same size (roughly) as would have been created by a
single threaded process.

Hope this helps,

Cheers,

Ian

PSAPREROGI

I got ORA-01652 (See ORA-01652.ora-code.com) while rebuilding the 14 GB index to a new tablespace and
the tablespace

has 16 GB free space. Before the error occurred, the 31 GB temp
tablespace had 13.5 GB

used.

Any idea why it created temp segments in the target tablespace?

How big the target tablespace would be? I thought 16 GB is enough.

Thanks,

Roger
