ABAP STACK & JAVA STACK

[former_member826926]

Hello Peers,

As a beginner, I've several doubts on ABAP Stack and Java Stack. Please resolve my doubts.

1) Which stack is recommended : ABAP stack or Java Stack or Dual Stack (ABAP+Java) and Why ?

2) If We’re using Dual Stack Scenario in our landscape, then in what ratio their instances are defined i.e. no. of ABAP stacks and no. of Java Stacks and On what grounds this ratio is defined ?

3) How anyone will decide that he’s going to create a HTTP request for ABAP or Java Stack and how numbers of these requests get decided ? On what parameters this depend and at which stage of architecture planning this should be defined ?

4) How does the system decide that which HTTP request will be sent to which Stack ?

5) If We're using Single Stack in our environment (Say ABAP), then how can we send HTTP request to JAVA stack, if such use-case appears in between implementation phase ? Is there any provision for referencing JAVA Stack from ABAP Stack and vice-versa ?

Thank You.

Hi Harsh,

ABAP is being opted to run ABAP based application server. ABAP stack is used to run ERP & NetWeaver applications, mainly MM,SD,FICO, etc.

Java is being opted for Java-based application servers. Java Stack is mainly used for SAP Portals and PI/ PO systems, Java Stack uses Java Threads to run applications,

Currently, SAP dual stack systems are end-of-support, and slowly getting outdated.
