Mobile - Beginner's queries

[Former Member]

Hello All,

I a novice in the field of MI. I did have an initial reading up of the articles which I could lay my hands own, but a few question remains:-

1. I am aware that certain softwares are to be downloaded and installed (on the server and at the client side). But is there any hard ware equipment required. For eg:- some sort of a transmission equipment for the Web AS to actually communicate with the Hand held device over the air?

2. What would be the bare minimum software/hardware required for me to code a small application using the MI frame work and test it out? I have good experience in Java and can tweak around with XML too.

My reason for asking these questions is to verify that whether I can actually design/develop a small MI application with the resources I have.

1. I do have NWDS SP7 and also an application server running Web AS. I do have very limited access rights on the Web AS.

2. I don't have any mobile devices like PocketPC. Would Mobile phones be of any use.

Any help would be appreciated.

TIA.

hello sachin,

here's my opinion.

for server and mobile client hardware requirements, please

refer to <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/developerareas/mi?rid=/library/uuid/cc489997-0901-0010-b3a3-c27a7208e20a">mi FAQ</a>.

for the transport layer, you're not necessarily required

for wi-fi transmission. MI exhanges messages in HTTP, thus

a network connection is at least required to synchronize

data with the middleware.

the MI client doesn't require that much high specs; but

this would depend on the kind of application you are

planning to create; and the performance you are planning

to achieve. by experience, at least 64mb of RAM is necessary.

developing the client app, doesn't require that much resources.

however, the middleware/backend part has a minimum H/W

requirements (pls refer to the WAS installation doc).

you might not be able to define objects in the MI server

if you have a very limited rights. but if you are to focus

on client development alone, all you need is a user with

synchronization rights. (this is to assume that somebody

else is working the middleware/backend configuration for you)

Smart phones (Windows Mobile) based can be used as long as

the CrEme JVM can run.

well, good luck...

just post back for other questions.

A few more questions (to Jo specifically)..

>by experience, at least 64mb of RAM is necessary

Is this the RAM required on the Pocket PC or the Mobile device, or you are talking about the WAS Server RAM.

>the middleware/backend part has a minimum H/W

This I assume resides on the Web AS (and not on the hand held device)

Thanks in advance,

Sachin.

Hi Sachin,

> by experience, at least 64mb of RAM is necessary

>> Is this the RAM required on the Pocket PC or the Mobile device, or you are talking about the WAS Server RAM.

I<b>t is the memory required in the pocket pc or mobile device not the WAS Server RAM. A client can also include a laptop.</b>

>the middleware/backend part has a minimum H/W

>>This I assume resides on the Web AS (and not on the hand held device)

<b>The middleware resides on the Web AS and the Web AS connects to the backend.

In some cases the backend can be in the same system as the middleware.

Let me know if you have any more queries and welcome to Mobile Infrastructure.</b>
