Re: Recovering WITHOUT tablespaces - 2001-08-16

I was bitten but this badly and thanks to all those people who helped me. This may some of you, so I'm posting it.

I wanted to extract one table as of a time the previous day. So I decided to recover to the closest time as possible before the unwanted change was made.
This meant that I only wanted two application tablespaces (data and index) out of many.

As I was told its possible, I assumed it would be OK if I went with the basics - system TS data files, RBS (3 out of 4 files), the datafiles of the application TS's and even member of each redo-logs group .

I recreated the control file, did the recovery to the point in time and opened it.
Now when I did a select on any object, I was hit with the following:

ORA-00604: error occurred at recursive SQL level 1
ORA-00376: file 2 cannot be read at this time
ORA-01111: name for data file 2 is unknown - rename to correct file
ORA-01110: data file 2: '/emc/vol1/oracle/product/8.1.6/dbs/MISSING00002'

I tried recovering again with all the RBS files as the last one also had online
public rollback segments.
That also didn't help and file2 was constantly being a pain - checking dba_data_files showed that it was belonging to the TOOLS tablespace. On closer examination I discovered it had 237 SYS and SYSTEM objects.

Another DBA must have loaded these objects in TOOLS t/s. Recovering DB with tools and the other essentials resolved the problem.

So, watch out for this in the future.
