ORA-00327: log string of thread string, physical size string less than needed string

ORA-00327: log string of thread string, physical size string less than needed string

Cause: A log file has shrunk in size. This is likely to have been caused by operator  or operating
system error.

Action: Restore the log file from backup. If backup is not available, drop this log  and re-create. If the database was shut down cleanly, no further action should be  required; otherwise incomplete recovery may be required.
