    Description:
    If anyone can assist, our oracle backups are failing with a permission problem (see excerpt). The backups are setup in the Oracle crontab file:

    Backup for Oracle logs started.
    tar -cvf /dev/rmt/0cn /exlibris4/oradata/aleph1/arch/
    Tar: /dev/rmt/0cn: Permission denied

    I've limited experience working with Sun Solaris 10 - but see that the permissions on the /dev/rmt directory is: drwxr-xr-x, owner is root, sys is group ... I'm wondering if this is the problem?

    Any assistance is appreciated. I submitted an incident to ExLibris but because ExLibris cannot remote in to our servers, they seem to be unable to assist.

    Resolution:
    From an ALEPH-NA DBA:

    root-ownership with those flag settings means no other account (including an Oracle account) can write to the device.
    If she can either chmod ugo+rw /dev/rmt/0cn to allow all users write-access, or run the backup as root, that should do it.
