Before you configure WebSphere® Adapter for SAP Software,
consider whether you will set up the adapters in a clustered environment,
in which the workload of the server is distributed across multiple
machines.
Before you begin
Before you begin to set up and use the adapter,
you must
possess a thorough understanding of the business integration concepts,
the capabilities, and requirements of the integration development
tools and the runtime environment you will use, and the SAP server environment
where you will build and use the solution.
Security The adapter uses the J2C authentication data entry,
or the authentication alias feature of Java™ EE
security to provide secure user name and password authentication.
For more information about security features, see the documentation
for WebSphere Application Server. The
adapter also supports secure network connections for both outbound
and inbound processing.
User authentication
The adapter supports several methods for supplying the
user name and password that are needed to connect to the SAP server.
By understanding the features and limitations of each method, you
can pick a method that provides the appropriate level of security
and convenience for your application.
Deployment options
There are two ways to deploy the adapter. You can either
embed it as part of the deployed application, or you can deploy it
as a stand-alone RAR file. The requirements of your environment affect
the type of deployment option you choose.
WebSphere Adapters in clustered environments
You can improve adapter performance and availability by
deploying a module on a clustered server environment. Clusters are
groups of servers that are managed together to balance workloads and
to provide high availability and scalability.
