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.
Is there any way I can correlate the PID in this display to find (or
verify) just which SP is spawning multiple times?
Is there any way I can stop this behavior? If only one occurance of
each of the 80 SP's lived in memory, that would make my server much
happier.
Any help or pointers would be much appreciated.
Thanks
Sean

The fact that some groups of these processes have the same memory size is
definitely related to the particular SP that the DARI process last executed.
But since these DARI processes are shared across all the agents, an agent
needing to run a SP will just pick an idle DARI to run the SP. So the
memory usage of these DARI processes may change over time.
The maximum number of these DARI processes will be the same as the maximum
number of agents that you have configured. This would only occur if every
one of your agents was running a SP at the same time though.

Matt,
Thanks a lot for the feedback.
I always thought the MAXDARI dbm cfg parameter controlled how many dari
processes were allowed to run concurrently. I seem to remember getting
an error to this effect, that was resolved when I bumped this value up.

I am trying to get a sense of requirements and best practices for Java

1. Is it required or recommended that any of the following be closed before

will still run succesfully if these open objects and connections are not
closed, are there any...

I am trying to determine the behaviour of stored procedures in DB2 V8.2.x in

First, am I right in understanding that the normal behaviour of a stored

and to be swapped out of memory when it is not needed any more?
Second, am I right in...

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

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
