3. 32 employees has to concurrently work in OLTP systesm, how many rollback should be created?
-- it is 8 rollback segments.
4. Where will you find the # of online redo logs and # of groups?
-- I guess V$log and V$thread.
5. When PCTUSEd crosses its thresold..
-- No insert will happen.
6. When PCTUSE limit reaches BELOW, it will be added to Freelist.
7. When you rebuild index..
-- Can you convert from Btree to Bitmap
-- Can you convert from Reverse to Bitmap ( i don't know the answer)
8. When you resize the datafile (shrinking), upto what point will you do.
-- To the last block of last object?
-- to the bytes of datafile Header ( this also I don't know)
9. When you add a logmember to a group whithout specifying the size,
what will be the effort?
