I've installed a fresh DB2 V9.1 server (Express-C). Now I see, that the
number of applications (db2 list applications) is growing all the times
when a script is run which makes some database operations. This is on
Linux.
I tested the same script against an older DB2 V7 on AIX and the number
of applications (db2bp) is growing by one, but then the db2bp
disappears, so the number of applications is not growing all the time.
Here is the script:
#!/bin/sh

During the delete loop I see the number of db2bp growing, I thing 1 for
every db2 statement. Why?
It's a big problem for me. I've never seen such a behavior before!
