Re: Recovery -- Can't place tablespace offline ?

Hi Prem,

When you place a tablespace offline, Oracle attempts to perform a checkpoint
on the datafiles associated with the tablespace to ensure it's consistent
after it's offline (else how do you write the dirty blocks in memory after
it's offline ?).

The problem of course is that the datafile(s) is stuffed and the checkpoint
can't be completed.

Therefore you need to use the 'immediate' clause to let Oracle know that a
checkpoint is not possible (or 'temporary' where Oracle will checkpoint
what datafiles it can).

The outstanding dirty blocks then get written to a deferred rollback segment
and applied when the tablespace is recovered and brought back online.

Cheers

Richard
