JCo Connection Rules

Understand default behavior when configuring SAP Mobile Server to SAP enterprise information system JCo connections.

By default, SAP Mobile Platform JCo connections follow these rules:
  1. Each distinct connection of credentials and connection parameters creates a new destination name.
  2. Each destination name may pool one connection.
  3. Each attempted invocation on a destination opens two socket-based RFC connections to the remote system: one for the user's JCo destination, and one for the associated JCo repository's automatically generated destination.
  4. By default, each destination may cache up to one idle connection for up to five minutes. Evict these connections earlier if the global connection pool maximum size is reached.
  5. Once the idle limit is reached, pooled connections are closed.
