Dialog processes and performances on 7.31

Hi all!

I'm just an humble developer (yes, the one keeping bothering you with opening http connections, checking indexes and so on) so if my question will sound silly, do not throw too many tomatoes!

We are facing some issues due an existing procedure (sadly implemented before my arrival with, imho, a non-sense architecture) which fill a bunch of our dialog processes, blocking this way all the activities from the users.

So, while I study the procedure and rewrite it from head to toes, I've to put some patches on it and I was wondering if there is any best practices/suggestion/rule/idea on how to setup the system, the number of dialog processes based on the number of unique users and so on i can check&discuss with the host&admin supplier.

I know it's a bit confusing, but I found myself in this puddle of mud and i'm still trying to find at least the way where i've to move.

Thank you all!

    Hello Simone,

    Hehehe ... humble developer ... like it :-) ... How times have changed. Tomatoes now. It used to be rocks :-)

    It sounds to me as though your program is dispatching tasks in parallel (RFC) and this is taking up all your DIA.

    If this is the case then this can be controlled with RFC quotas via tx RZ12.

    Please have a look at the following notes to give you more insight into what you can do to control DIA utilisation.

    • Well, yes, it's almost lunch time here so tomatoes for a good salad... 😀

      Yes, the cause seems to be that, but still i'm digging in the code to understand why this kind of solution has been implemented! -sighs-

      Thanks for the notes, i'll give a look asap!
