Hi All ,

the ENV is oracle on SunOS 5.8.
recently .... my hot backup log shows the following error .

Altering tablespace MARKETFIRST_LIDX out of backup mode...
ORA-09925: Unable to create audit trail file
SVR4 Error: 13: Permission denied
Additional information: 9925
ORA-01075: you are currently logged on
SP2-0306: Invalid option.
Usage: CONN[ECT] [logon] [AS {SYSDBA|SYSOPER}]
where <logon> ::= <username>[/<password>][@(protected)>] | /
ORA-01005: null password given; logon denied
SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus
Altering tablespace FCCUST_DATA into backup mode...
Tablespace altered

The directory mentioned as in AUDIT_TRAIL_DEST exists with proper permission
and free space.I am able to create files in that directory.So i'm not
run out of inodes ... i hope.

i am able conn to DB as

$sqlplus /nolog
SQL > conn / as sysdba

This works fine without any issues.
but i don't know why the backup fails.

Can someone please help me sort it out ?
