Data Source Connections

A data source connection is a physical connection definition that provides runtime connection to enterprise information systems (EIS), that in turn enables data to be mobilized by Unwired Server to client device via synchronization or messaging. Before you create publications or subscriptions, or deploy packages, you must first define database connections.

For Unwired Server to recognize a EIS data source, you must define a connection to that data repository. The connections are defined in Sybase Control Center with the Unwired Platform perspective, and are known as server-to-server connections because they are opened by Unwired Server.

In Unwired Platform you create a connection template from which you can replicate connections. Connection pools allows Unwired Servers to share pools of pre-allocate connections to a remote EIS server. This preallocation avoids the overhead imposed when each instance of a component creates a separate connection. Connection pooling is only supported for database connections, and the size of the pool is controlled by the Max Pool Size property of the connection.

• Connection Templates
  A connection template is a model or pattern used to standardize connection properties and values for a specific connection pool type so that they can be reused. A template allows you to quickly create actual connections.
• Changing Connections to Production Data Sources
  Platform and domain administrators can change endpoint connection information when moving applications from development or test environments to production environments.
• Viewing and Editing EIS Connection Properties
  View these settings when troubleshooting connection problems, and make changes as needed to correct a problem or improve performance.
• Tuning Connection Pool Sizes
  Platform administrators can tune the maximum pool size to data source connections for improved performance. This ensure that adequate EIS resources are allocated for servicing the Unwired Platform runtime.
