what are the different technical systems are there in the landscape.
The technical system describes the physical view and the business system the logical view, respectively.
So in most cases you must define both but while a technical system can only link to one WEB AS, more than one business systems can link to the same technical system.
Tech System - Holds the tech details like installation no, db instance.
Technical Systems are of following types:
Technical systems are application systems that are installed in your system landscape. An example of an application system is a Customer Relationship Management (CRM) server. In the SLD, there are five types of technical systems:
1.)WEBas java,
2.)Standalone JAVA
3.)Third party
4.)Web as ABAP
1) Web AS Java
Web AS Java systems consist of one or more instances and each instance is installed on a separate host. An instance itself consists of cluster nodes that can communicate with each other.
2.)Standalone Java
Standalone Java technical systems are standalone Java applications that are installed in a computer system from an administration perspective. They can also be installed as an operating system service or as a daemon
Web AS java belongs to the NetWeaver Comes with both ABAP and Java, Standalone instread comes separate from the netWeaver.
3) Third party technical sytem
It can be any of the technical sytem. let us say if you want to send a file to R/3, here the file reside in your local system. for that you can define your local system as a third party technical system.
All those machines that comes under non sap, belongs to the third party.
4.) Web AS ABAP technical systems, ranging from any SAP system to an APO server or CRM server, are based on the same Basis Component (BC), which includes the ABAP interpreter, ABAP Dictionary, ABAP Workbench, and so on. A dedicated database, which stores most of the data of the BC and the application components, is associated with the system.

What is your file size and how many records are there in your file ? which idoc your using ?
The file size that your server can process depends on various different aspects like the server hardware sizing, total available memory form both Java and ABAP side, the kind of interfacing you are trying to achieve, if your interface needs a complex mapping etc. Although there is no correct picture on theoritical Max file size, it will depend on the specifics of your landscape.
I personally feel that, processing a 2 GB file is not a good idea as the message when converted to XML its size multiplies atleast 3.5 times to 7 times, which gets persisted at various stages of logging that the system does. You may want to consider other options like splitting the messages into smaller chunks, having no or minimal mapping and configuring the recordset per message property.
Personally in one of the implementations we have had to process a Max file size of 350MB which gets processed once a month and that too during non-peak working hours.

Selecting an IDOC depends on your requirement.
example: if it is purchase order then the idoc would be orders.orders05
if it is invoice,idoc would be invoic.invoic02.
