Default size for undo tablespace

I had the OMF turned on which was supposed to create an undo tablespace 10m in size.

I ran the following statement I did not set the undo_managemnt paramater. But what I got is an undo tablespace of 67m.

create database db
default temporary tablespace temptbs
undo tablespace undotbs;

If I ran the following statement instead and with the undo_managemnt paramater set to auto, then I got an undo tablespace of 10m

create database db
default temporary tablespace temptbs;

Also, If I ran the following statement and with the undo_managemnt paramater set to auto, then I got an undo tablespace of 10m

create database db
default temporary tablespace temptbs
undo tablespace undotbs;

My question is why did the first statement give me an undo tablespace of 67m? Received on Sat May 03 2003 - 21:14:43 CDT
