[Newbie] various general questions about XI

48 Views

Hi,

I'm trying to dive into XI at the moment and read the SAP Help for XI but many things are not clear to me.

<b>1. Pipelines</b>

I learned that Pipelines consist of several elements. These elements are using the Pipeline Services. What I didn't understand is whether there are only 3 Pipeline Services (logical and technical routing and mapping)? Is it possible to include own services? Which programming languages are supported for that?

Also I wonder if one can compare Pipelines to the Message-Flows within Websphere BI Message Broker (formerly MQ Integrator Broker)? Can Pipelines adapt such complex scenarios as Message-Flows can (e.g. output of messages to more than one receiver, compose output-messages out of several input-messages or database-entries)? Or is that the purpose of the business processes (handled by the bp-engine)? And if so how does the bp-engine use Pipelines? (and more general, what is the difference of bp-engine and integration engine - Especially about the bp-engine I found only rare information in the online help)

<b>2. Proxies</b>

Proxies are generated out of message-interface-descriptions in the integration server. They transform proprietary message-formats to the XI-Message-format. They communicate with the proxy-runtime. But what's the task of the proxy runtime (is it just like an API)? Is the proxy-runtime a part of the integration engine?

Do I need a WAS 6.40 to use the proxies of XI 3.0 or is it enough to have any SAP WAS?

<b>3. Tools</b>

Development, configuration and administration is done with the integration builder and monitoring with the runtime workbench?

<b>4. Pricing</b>

I can't find any piece of information about the price of XI 3.0 + WAS 6.40

<b>5. JMS-Adapter</b>

I read that the JMS-Message must already be formatted in XML? So the JMS-Adapter does no transformation? Does that mean I can not integrate existing applications which for example send plain text to MQ Series - do I have to make the transformation of that plain text within my application?

Thanks for you time.
