db27.2 fp7 on AIX5.2
I just bounced the database (as a specific db2dari process had reached
user memory limit), and some (orpahned) db2dari processes are still
there.
db2fenc1 42682 1 108 Sep 28 - 14308:10 db2dari (81842)
....
db2fenc1 90546 1 108 Sep 28 - 431:39 db2dari (63356)
Does anyone know if this is normal and, more importantly, whether
they'll still be picked up by my sps?
Any help appreciated.
Thanks
Bruce

Given the cpu consumption I'd guess they're stuck in an infinite loop in
a stored procedure.
The processes themselves are orphaned...they won't interfere with new
calls (other than keeping libraries loaded, and slowing down your system).

Thanks Sean.
Final question - sorry, but are you implying the high CPU usage is due
to an inifinite loop in code (i.e. a code bug)? The reason the DB was
bounced was because the application could no longer load libraries to
(2 specific) db2dari processes as the latter had just about reached
the memory ulimit.
We see runaway processes like this fairly often, and it 'usually' ends
up being a problem in the sp (couldn't be a bug, right) :-). The only
way to know for sure is to attach a debugger to the process and see what
code it's stuck in.
Come to think of it, another possibility would be recursive
traps...sometim es the stack can get hammered so badly by an sp, that our
trap handler goes off in space.

Good afternoon,
I'm trying to set up a clustered DB2 v7.1 database on Redhat Linux
7.3. I've followed the instructions (as far as I know) in the
accompanying documentation to set up the database on 2 nodes.
Running db2start on node 0 I get the following message:
11-19-2000 10:12:44 1 0 SQL6048N A communication error
occurred during START or STOP DATABASE MANAGER processing.

Dear all,
I have simulated the windows MULTI application with a java program calling
the SQLTP1DL proc referenced as DB2DARI application, on Linux Intel or
ZLinux. If the proc is NOT FENCED, there is no pb and the program works
fine. If either the proc is FENCED, or FENCED THREADSAFE, I get a SQL1042C,
or the instance crashes on ZLinux (V8.1 FP4).
The proc does a return(SQLZ_HOLD_PROC):
$ /opt/IBMJava2-131/bin/java sqltp1ri 1

Helpful folks,
Platform: DB2 UDB v7.2, Win2000, KEEPDARI=YES
I am trying to reduce memory usage of our SP's. We only have 80 or so
SP's but in the Task Manager/Processes display, there are over 200
entries for DB2DARI.EXE. Interestingly, there are many sets of these
entries which have the exact same memory usage size. It would appear
that for many of the SP's, there are multiple copies in memory.

Which of the UDB 8.2.2 ESE unix executables really need to
gain root privilege while they are running?
In my installation, the db2sysc file is owned by the instance-owner
(and relevant admin group ownership), but when the db2-instance starts
running (manually started via "su" as the instance-owner),
the db2sysc process requests root access.
I think that db2fmcd also requests root privilege.

Hi folks,
The sentence "If you are an HACMPâ„¢ user, you must use the ha_db2stop
command to stop DB2 instead of the db2stop command. If you use the
db2stop command instead of the ha_db2stop command, you will trigger a
failure event.". If I also do HADR with HACMP, should I also use the
ha_db2stop command, or just db2stop command?
Thanks in advance,

Hi, Friends,
I need to know how to stop all database process even after db2stop.
How can I stop all database processes?
I have finished upgraded our system test and UAT region from 32-bit to
64-bit.
I followed the following for my system test region:
1. log on aix with root
2. stop the instance
3. db2iupdt -w 64 instance

Hi!
I'm trying to set up a database instance on a prime Linux server,
using db2 V9.5 with fixpack 1 applied.
I issued db2set DB2RSHCMD=/usr/bin/ssh
After adding 2 partitions, when issuing db2stop (as instance owner),
I have to give the password 6 times.
When i the run db2start it suffices with 3 times.
What did I miss?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
