Mladen,

Thank you very much for your suggestion. I tried
exactly that - offline the tablespace and restore the
datafile and - guess what? - it failed because of the
lock being held against the datafile. That is what
lead me (and the Oracle support guy) to bounce the
database. Now I may be less than "half way competent
member of damanagement" (whatever it means), but based on your advice you may be not much better. In
the future if you can't refrain from isults, please do
not reply to my posts. I'm asking for help and
advice, not an insult.

It's review time, so everything you do is wrong, as
a cost saving measure. Any half way competent member of
damagement can tell you that.In this particular case though,
you could have recovered the datafile online. You should have
offlined the tablespace, restored the datafile and recovered the
datafile.
Restarting the database was not not necessary. Also,
one of my
religious rituals is to perform a checkpoint after
the tablespace has been successfully brought online. The reason is
to record the
new timestamp to the control file and make sure that
all files
have the same timestamp (checkpoint process updates
file headers
during checkpoint).

Hi I got the following error in an alert.log file.
Aparently it was a result of some UNIX issues on a
hdisk, which have been resolved some time later ..

"Fri Dec 5 18:28:10 2003
KCF: write/open error block=0x3571 online=1
file=68 /u21/ORACLE/pfiat02/isysx01_12.dbf
error=27063 txt: 'IBM AIX RISC System/6000


Error:


5: I/O error
Additional information: -1
Additional information: 16384'
Automatic datafile offline due to write error on
file 68: /u21/ORACLE/pfiat02/isysx01_12.dbf"

The file in question had status = 'RECOVER" in the
v$datafile and status = 'AVAIALBLE' in
dba_Data_files. I attempted to restore the file


after


taking it offline, but couldn't due to a lock. I


ended


up bouncing the database an recovering this file.


I'm


wondering whether I should have tired to recover


this


file first without bouncing the database. If


anyone


has any experience with that issue, could you let


me


know whether what I did was wrong or not (and


why). Is


there a document that I can read on this?

thanks

Gene
