ORA-00444: background process “MMAN” failed while starting

Filed under: Database,Oracle — mani @ 10:33 pm

Generally we run into this error while restoring database or other instances of starting the database.

RMAN> startup nomount

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of startup command at 11/14/2011 22:09:05
RMAN-04014: startup failed: ORA-00444: background process “MMAN” failed while starting
ORA-07446: sdnfy: bad value ” for parameter .

RMAN> exit


Alert log is not able write into the log since directory defined in init.ora file doesn’t exist.


For example directory  ‘/local/opt/oracle/admin/dsp0001/bdump’ doesn’t exist.


Create the directory that is missing and start the database again.

mkdir -p /local/opt/oracle/admin/dsp0001/bdump
