DBEXPORT error

Posted By:
Date:

Hi there,

I'm looking for help regarding DBEXPORT.
I'm trying to do "routine" maintenance on my "huge" tables, i.e. extent
sizes, fragmentation, etc.

My setup:
Informix 9.21.UC3
DBTEMP=/usr1/dbexport (34GB drive)
DBSPACETEMP=dbs_temp (4GB (2x2GB slices))
user = informix

Solaris 2.7 (1GB RAM, 2x400MHz CPU)

At first use of DBEXPORT, I got the following message after a while:
Disk space may be full. Cannot write to file. Dbexport aborted.

Searching the Internet, I got the following info at:
http://www-3.ibm.com/software/data/informix/pubs/library/notes/relnotes/ids_
win_fixed_and_known_defects_9_30.txt

bug_number 118229
description AN DBEXPORT OF A TABLE CONTAINING 0XFF (ASCII 255) WILL FAIL
WITH "DISK
SPACE FULL. CANNOT WRITE TO FILE. DBEXPORT ABORTED."
product_code DBATOOLS
component_code


The table where DBEXPORT stopped contains a BYTE field.
Then I tried a manual UNLOAD TO FILE SELECT * FROM TABLE of the specified
table using DBACCESS.

The UNLOAD failed and the file size stopped at 2.1GB:
-rw------- 1 informix informix 2147483647 Apr 28 03:06 person_photos.unl

Then I got the following error:
Write failed. 2916 rows unloaded (check ulimit or disk space).

Here is my ulimit output:
$ ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 8192
coredump(blocks) unlimited
nofiles(descriptors) 64
memory(kbytes) unlimited

And my df -k output:
$ df -k
Filesystem kbytes used avail capacity Mounted on
/proc 0 0 0 0% /proc
/dev/dsk/c0t0d0s0 14313947 5869968 8300840 42% /
fd 0 0 0 0% /dev/fd
/dev/dsk/c0t1d0s6 35009161 6536916 28122154 19% /usr1
/dev/dsk/c2t1d0s6 22194372 9 21972420 1% /usr3
swap 3567592 336 3567256 1% /tmp


Then, just for the hell of it I tried doing the UNLOAD TO FILE SELECT * FROM
TABLE
using ROOT.
Still the same error, and again the UNLOAD file size stopped growing at
2.1GB

What am I doing wrong???
I cannot export my tables to do performance tuning.

PLEASE HELP!!!!

Thanx in advance.........
