Hi,
if the BYTES_FREE in temp tablespace datafile is 0, what does it mean?

Well, I started all these checking when my DML statements started to 'hang'. Simple insert into select * from started hanging, which used to take about a couple of seconds.
And my select queries are running exceptionally fine. But my DMLs are getting problematic. Moreover, my database (9.2.0.5) has also now a problem of not letting any new logins. It simply hangs. The existing sessions are running fine (may be something to do with archivelog ?)

I ran the following queries.

SELECT TABLESPACE_NAME TS, BYTES_USED, BYTES_FREE
FROM V$TEMP_SPACE_HEADER

gives me 0 bytes free,
TS | BYTES_USED | BYTES_FREE
TMPSEG | 2147483648 | 0

And also:

SELECT
d.tablespace_name ts_name,
NVL(d.bytes / 1024 / 1024, 0) file_size,
NVL(t.bytes_used/1024/1024, 0) used,
d.autoextensible autoxtnd
FROM
dba_temp_files d,
v$temp_space_header t
WHERE (t.file_id (+)= d.file_id) gives me the
following:

TS_NAME | FILE_SIZE | USED | AUTOXTND
TMPSEG | 2048 | 2048 | YES

Does it need any repairs? Or some other diagnostics need be run?

Thanks,

Sujit
(urgently need to fix the dml problem)

When you exetute some ordering statement, oracle will allocate a temporary segment into the temp tablespace and will never deallocate it because it will be more performant next time for reuse. So, it is ok when you see o bytes free for tem tablespace.
I believe that archiving destination full is most probably the reason for users not being able to login.
What additional errors show up in alert.log file?

Best luck.
