Cannot shrink the undo tablespace
694243Apr 8 2009 — edited Apr 14 2009Hello!
I have run a very long procedure, which generated 15GB undo information. Now I can see in the enterprise manager, that the undo tablespace is empty again. I tried to resize the datafile, but I receive "*ORA-03297*: file contains used data beyond requested RESIZE value". How can I shrink the tablespace without dropping and recreating it?
I tried also
purge recyclebin;
I still get ORA-03297 if I try to resize the datafile.
I wanted to try something like
ALTER TABLE xxxxx UNALLOCATE UNUSED;
or
ALTER TABLE xxxxx SHRINK SPACE;
but are there any tables that save the undo information?
Regards.
