I cannot start the database. Starting it via services produces the result above with the following error logged...
in the ALRT.log:
ORA-1122 signalled during: alter database "cafe" open
Attempting to start the database via the svrmgr30 program produces the following errors:
LCC-00161: Message 161 not found; product=RDBMS80; facility=MGR
ORA-12203: TNS: unable to connect to destination
- connect internal
- startup mount
- alter database datafile '/directory/filename' end backup
- Repeat step 4 for each and every datafile.
- alter database open
- shutdown immediate
- Take a cold backup of your database.
You will not be able to open the database until all of your datafiles are out of backup mode. Once you have opened the database, you will want to take a backup of your database so that you will have a good clean backup to start from after recovery from this failure.
