Hi all,
I have a DB2 8.2(fk14) running on Solaris 9 server. Once the DB2
working, I can see more than 30 DB2 processes(db2sy sc) running at the
same time. Is that normal?
Thanks.

On UNIX systems other than AIX(R) and SCO OpenServer, the db2sysc process is the
only process shown for all server-side processes (for example, agents, loggers,
page cleaners, and prefetchers). On Solaris systems, you can see these side
processes with the command /usr/ucb/ps axw.

I'm on RHAS 2.1 (linux). If:
the db2sysc process is the only process shown for all
server-side processes (for example, agents, loggers, page
cleaners, and prefetchers)
then why do I see processes (with ps command) such as:
db2pclnr (Page Cleaner)
db2pfchr (Pre Fetcher)
db2agent (Coordinator Agent)
db2loggw (Log Writer)
???
Plus, what I think the OP is asking is: is it normal to see
30 db2syscs?

It is normal to see 30 db2sysc if there are 30 instances creeated and active for
example.
On Solars - which is what the OP is asking for - there are special commands to
show server side processes:
/usr/ucb/ps axw
or:
db2ptree
or:
db2_local_ps

Thanks all.I do ask " is it normal to see 30 db2syscs?".
If you are using Solaris, please let me know how many db2syscs process
running in your system using "db2_ps" command.

Our production DB2 V8 FP7a, Solaris 8 shows the following:

Oh, and another point - as Jan has pointed out, they're not all
actually db2sysc, as in the system controller, processes. Use
db2ptree to see what they actually are. Only one of our many
processes is an 'actual' db2sysc:
$ db2ptree | wc -l
982
$ db2ptree | grep db2sysc | wc -l
1
really? you can see 943 db2sysc processes using db2_ps,WOW. how many
instance you have? I believe it must have lots of users/applications
connecting to the DB2. For us, we only have 1 instance, and 1
application uses it.
BTW, I know the db2ptree shows the detail threads info, always 1
db2sysc. Our system administrator doesn't care about it, only ask me
why the DB2 take so many process resources.
Thanks Tomas for your info.
One instance, one database. 16 application servers using connection
pooling - we get to see a lot of (mostly idle) connections!

Hi,
I am trying to understand the performance implications of running a
number of separate ActiveXexe processes as opposed to a single

I have been told that Windows does not allocate a fixed memory space
to its processes, so they are always paged off to disk when inactive.
However, all the threads in a single process operate within the same
memory space, so are relatively...

We currently have a routine that "forks" out (to use the unix term)TSQL
commands to run asynchronously via SQL Agent jobs. Each TSQL command
gets its own Job, and the job starts immediately after creation.
Sometimes we can have too many of these jobs running at the same, and
the box crawls to a slow speed until the jobs finish up.
Is there a way we can limit the number of active jobs running under the
SQL Agent at one time? Or is...

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.

I understand that Python has them, but PHP doesn't.
I think that is because mod_php is built into apache, but mod_python

python still have long running processes (LRP)?
Do LRPs have to do with a Python interpreter running all the time? Or
is it something else?
