Re: Data Recovery

This is the message I get when I try to start the database:

LOG: database system was interrupted while in recovery at 2005-03-16
16:07:58 EST
HINT: This probably means that some data is corrupted and you will
have to use the last backup for recovery.
LOG: checkpoint record is at 2B/553CED30
LOG: redo record is at 2B/553CED30; undo record is at 0/0; shutdown TRUE
LOG: next transaction ID: 118419066; next OID: 50155349
LOG: database system was not properly shut down; automatic recovery in progress
LOG: redo starts at 2B/553CED78
LOG: record with zero length at 2B/62360AB8
LOG: redo done at 2B/62360A88

Thanks,
