Home -> Community -> Mailing Lists -> Oracle-L -> RE: ALTER TABLE MOVE command causes table to grow
Yes, it's from DBA_SEGMENTS. And there was no DML against the table during
the ALTER TABLE MOVE command which is when it grew.
Re the 10% PCT_FREE there's minimal update activity. It has constant low level insert activity during the month, then a batch delete at the end of the month followed by a batch insert at the beginning of the month. But even if that wasn't the case how would a low PCT_FREE cause it to grow during the MOVE command? I'm not certain I understand what you're aiming at there.

just to be certain we are on the same page,
you mention uniform sizing which is on
the tablespace level, so I want to make
sure the PCT_INCREASE you provided was pulled
from dba_segments. if so then i'd say a bit
more info would need to have some light shed
on it persay was there much DML put against
this table last week. a PCT_FREE of 10%
wouldn't be such a good idea for a table
with varying length column data.

you didn't mention the PCT_INCREASE of this segment.

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,
