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
