Home -> Community -> Usenet -> c.d.o.server -> Please help salvage database
Gentle People,
We are attempting to salvage most of the data in this database. Oracle 7.2 on OpenVMS 6.1
(1) we inherited a nearly non-documented oracle database in the throes of
death, so we have very little information currently about the nature of the
database configuration (ie. what tables exist in which tablespaces, and what
each of the datafiles are related to).
(2) we lost an 8GB hard drive which contained three datafiles (which we are
willing to sacrifice to the gods in order to bring the db back online). The HD
was restored, and a back-up of the three datafiles was restored as well from tape.
(3) when starting Oracle, it requests media recovery on the three files.
(4) we have not been able to complete the media recovery process. The database
is in noarchivelog mode, AND there are no online redo log files to be found
anywhere on the system. Thus, we can only cancel out of the recovery process.
(5) we tried dropping the datafiles offline and restarting the db, but in this
scenario oracle would not start, due to a missing table needed for dml/query.
Presumably this table is in one of the three datafiles, and judging from the
datafile names, I would guess it is an index.
What we would like to do is: force the database to startup and mount, regardless of the state of those 3 datafiles, as we will be exporting one main table and starting over on a different environment. We have poured through all the scenarios in the Server Admin guide, but there is little guidance if recovery is not successful. We need concrete instructions to give to the db to either drop the datafiles and have the db 'forget' them, or to make the recovery proceed without online redo logs.
Hope someone can help.
Regards,
Brian
