What AppModule Pooling configurations take in effect for my use case?

PrabasMar 29 2018 — edited Mar 31 2018

Hi Experts,

I have 2 applications (App1 & App2), both refer to same Datasource.

App2 is deployed as an adfjar and is added to App1 as a dependent jar.

App2 taskflows are being used in App1 on a separate jspx pages..

App1 can have 200 concurrent users and App2 can have 70 concurrent users.

Here is my question:

Now while tuning the application module. Should I tune just App1 Appmodule to accommodate 270 users?

Thanks,

Prabas

I believe to access app2, you are going to use app1. app1 is used by 200 users. Same 200 users are going to see app2 also if they all decide to launch app2 page from app1.

Now how are you going to get additional 70 users.

I believe the better way to put it is

200 users can access app1 concurrently. Out of those 200, 70 might be accessing app2 from app1. At the end you only have 200 users for app1. So you should make app1 for 200 users only.

If you say initially app1 is for 200 users but because of app2 (inside app1), we are going to get new set of 70 users then yes, you need to configure it for 270.

Thanks

Well, not quite true. The first problem is that we don't know the jdev version the OP uses.

@"Prabas" which jdev version do you use?

Next, we need to know if you use the application module from app2 as root application module within the pages or as dependant application module from app1. Then we need to know who you use the taskflows (isolated or existing and if they share the data control). These parameters have an influence on how many application modules are used and how many connections to the db are needed or used.

@"Prabas" you should read http://www.oracle.com/technetwork/developer-tools/adf/learnmore/adfloadstresstesting-354067.pdf  for some background info on stress testing and Andrejus Baranovskis Blog: Stress Testing Oracle ADF BC Applications - Passivation and Activation for some practical sample on how to test your app.

Thanks for response @"SanjeevChauhan"@"Timo Hahn"

@"Timo Hahn", we are using JDeveloper 12.1.3.

  • we need to know if you use the application module from app2 as root application module within the pages or as dependant application module from app1 ---> Apps2 as root application module within the pages
  • Then we need to know who you use the taskflows (isolated or existing and if they share the data control)---> Shared data control

@"Timo Hahn"

In this case Should I tune App1 for 200 and App2 for 70 concurrent users?

(if we consider 200 & 70 users mutually exclusive)*

Answer

Yes, any way you should monitor the number of connections used in a load test to make sure you get it right.
