How did you perform the move? Was the operation done in parallel?

No LOBS. Here's the definition:

What the table definition? Are there any LOB's on it?

Had an annoying surprise last week. A table had grown unexpectedly large and I scheduled a time over the weekend to move it to its own tablespace from my "medium" tablespace.

The table ended up growing 50%. I had anticipated it might grow somewhat given the PCTFREE of 10% but freeing up that space in the blocks should, at most, have caused it to grow by 10% (assuming that 10% was completely full).

Does anyone have ideas as to why it would have grown by so much? Indexes are in a different tablespace and the only other change was from an extent size of 4 meg to one of 25 meg. Both are dictionary managed tablespaces.

Oracle 8.1.7.2
Solaris 2.6

Thanks,
Jay Miller
