Error: ORA 01172 recovery of thread 1 stuck at block 27269 of file 3 ORA-01151: use media recovery to recover block, restore backup if needed Cause: Crash recovery or instance recovery could not apply a change to a block because it was not the next change. This can happen if the block was corrupted and then repaired during recovery. Action: Perform a RECOVER datafile for the file containing the block. If this does not resolve the problem, then restore the file from a backup and recover it again. Are you archivelog or noarchivelog mode? Try this first 1. SHUTDOWN IMMEDIATE; 2. STARTUP MOUNT; 3. RECOVER DATABASE; 4. ALTER DATABASE OPEN; If this does not work then you will probably have to do media recovery. The type of recovery depends on type of archive mode you are running. Look at alert log for additional info such as file needing media recovery. The type of file needing recovery also determines type of recovery.
