I tried to increase the size for these two datafiles manually, it failed, and I got the same errors as before--

ORA-01653:
unable to extend table xxx by 1024 in tablespace 'tblspc'
ORA-09217: sfsfs: failed to resize file
OSD-02081:
Message 2081 not found; product=RDBMS73; facility=SOSD
(OS 1)
ORA-09217: sfsfs: failed to resize file
OSD-02081:
Message 2081 not found; product=RDBMS73; facility=SOSD
(OS 1)

Any idea what should I do to fix the problem? Thanks in advance.
