| First of all I'd like to thanx all of you for answers!
|
| I've done some tests today and I'd like to show you results and problems.
|
| All my VB components are correct configured properly (threadings models,
| type of execution etc.). I have one class thas is responsible for all
| connection to the database. It also independet dll.
|
| All my clients write now messages into event log.
|
| Problem:
| When I start one client and than start long-lasting operation I can start
| second client, but it waits until the first client ends its process. Looks
| like database locks but it is not.
|
| Suddenly I've found in log event, that my second client can't initialize
| com+ object (stops when I call "set a = new MyDll.Function"). When the first
| client realises or creates new object than some resouces are free and second
| client goes on, but stops when it once again needs new object. So it looks
| like problems by resource pooling in com+.
|
| And now the hammer! All runs without problems when... I split my com+
| aplication into two aplications! One has only my "db" classes, second the
| rest of dlls. But where is the explanation? Two dllhost.exe mean tousand of
| out-process calls (almost all my dll uses "basis-dll") and that degrees
| preformance. And this configuration causes also problems with transaction in
| stored precedures of Oracle8i.
|
| Thanx for any help. I have 5 days to lose the problem...
|
| Greets,
| Adam
