Have you tried recover datafile '<full_path_of_datafile>'; alter database datafile <full_path_datafile_name> online; Regards Joseph Amalraj Juan Carlos Reyes Pacheco <juancarlosreyesp@xxxxxxxxx> wrote: Hi, please, The database was started up, when a datafiles was locked by a os program, and there was a pending to recover transaction, on that datafile. So the database started but that datafiles moves offline, with a pending recovery transaction. I set online the datafile and restarted the database and the problem was still there, and because it was urgent, and I didn't have time to ask, I solved the problem in other way. But checking in oradebug wakeup command, I'm asking If I had to wake up the recovery process to get the recovery to start immediately, wihch was the correct step?.
