    First thing to check:

    oraarch directory full?

    Next thing to check:

    What does your alert<SID>.log file say?

    Put in a df -g and check the sapdata and oraarch filesystems whethere they are filled up completly.

    Also check whether you see anything in alertlog file.

    Database log mode No Archive Mode

    Looking very strange that your DB is in No archive mode...then file system(arch) issue should not be there

    Put your DB in archive mode and let us know the status.
