Within each service integration bus you can create multiple gateway instances. You create web services gateway instances to partition the total set of gateway and proxy services into logical groups to allow simpler management. The gateway provides you with a single point of control, access and validation of web service requests, and you can use it to control which web services are available to different groups of web service users.
For a high-level task view of how you configure the web services gateway as part of an overall bus-enabled web services configuration, see Enabling web services through the service integration bus.
Before you can work with the web services gateway you must Plan your bus-enabled web services installation, ensure that every stand-alone server or cluster that is to play a bus-enabled web services role is a member of a service integration bus (refer to Configuring the members of a bus) and create a Service Data Objects (SDO) repository on every stand-alone server or cluster that is to play a bus-enabled web services role.
Bus destinations are already partitioned by the service integration bus, so each gateway instance is limited to gateway and proxy services within the same bus. However, gateway services can then map to target services that are available on other buses.
To create a new gateway instance, complete the following steps:
You are now ready to create a gateway service or create a proxy service for this gateway instance.
