Unixware 7.1 crash with Informix 7.30 UC2
Posted in 1999
Topics: Installation, Setup & Upgrades, Platform-Specific Issues, Versions, Editions & End-of-Life
Hello! We have the following system: Unixware 7.1.0 Informix IDS 7.30 UC2 The system is working, but the server hangs randomly without reboot (after 30 min to 2 hours), we can only see that the server's monitor flashes. We have read that Informix 7.30 UC6 with HP-UX works fine, can we solve this problem on Unixware also with UC6? We downloaded and installed the unix patches successful. TIA: Nick

Hangs how? Any messages in the Informix message log? Anything written
to the CONSOLE device/file? What does onstat -l show? What do the
onstat header lines show as the engine's status and blocking status?

We use the following configuration, and that is how the crash happend.
====================================================
I.
1. the PC: Pentium 200 Mhz,128 MB RAM, 4 GB SCSI Winchester
2. installation Unixware 7.1.0 - OK.
3. downloading UnixWare 7.1.0 patches - OK.
4. installation IDS 7.30 UC2 ( with all settings from the ../release
file ) - OK.
5. nobody uses the server-machine,we can test it
====================================================
II.
1. we are using PowerBuilder 6.5 client applications with IFX-Native
driver
2. we have 3,4,5 connections,
+ we use onperf monitoring - all the programs runs correctly
3. only these applications are running on the server-machine
4. after 20 or 30 or ... minutes the server-machine crashes,
the servers screen flashes, the keyboard is locked, you cannot
login neither
from the client-side, EndOfLife :-)
6. the crash come randomly
5. we tested it on an other machine ( HP LH PLUS SERVER ) other type
of memory,cards,winchester,etc...
( I.2 - II.6 ), but the result was the same
====================================================
III.
we wrote a "brutal" script for testing the server without
client-connections:
1. server-machine ON
2. login informix
3. oninit
4. run script:
script begin-----------
while true
do
dbaccess sysmaster - <<@
select count(*) from systrans@
done
script end-------------
5. no other applications run on the server-machine
6. after 1000-1300 times the server crashes
7. parallel we had two other loop under unix for testing the
environment
-> while true do onstat -a >> file.1; sleep 5 done
-> while true do sar -A 1 1 >> file.2; sleep 5 done
8. here you can see the END of these two files i.e. the last onstat
-a, and sar -A 1 1
