Hi All,

I am looking for AM pooling recommendations parameters for 400 concurrent users.

brief about the application:

the application contains 5 model and 6 UI controller projects

one module taskflows are using in other projects as libs

each project may contain about 150 task flows

we keep on observing when more than 100 users system is going down( we see admin/managed servers are going to admin state)

we try to tune the application with following-assuming for 150 concurrent users. for all 5 App modules.


Limited row fetch size:10000


I am looking for recommendations to improve system stability and improve performance. we appreciate your great suggestions.

Thanks in advance.

    Generally Reducing the Traffic between the Client and the Database During Users requests and Commit Operations Is the Key Solution ,for the Application, For Example Any Computed Fields in the Database Can be Transferred as Transient Attribute in the EO and VO Models,

    Reducing the Number of Fetched row per time is also recommended,

    But for now , after you finished designing your application and also you have a shared resources ( Task flow Lib ) , then you should consider Clustering the application on the Server  and Manage the High availability is highly recommended, this will maintain the required number of concurrent users without fail-over

    There are a lot of References on this topic,  I choose those 2 links, wish they are helpful for you,

    High availability
