Definition
Connection type: Pool
The ITS maintains a pool of RFC connections with a fixed size. If a connection is of the pool type, an existing RFC connection can be used. A pool user must be an anonymous SAP user.
By default, pool calls are stateless calls, with a small difference, however:
In case of stateless connections, the connection is always closed after a call.
In case of pool connections, the R/3 context is deleted but the connection is returned to the connection pool. This reduces the amount of connections needed.
You can use a free connection from the connection pool, where:
conn.login = user.login
conn.language = user.language
conn.client = user.client
If no connection is available, the least recently used connection is closed and a new connection with the appropriate user, language and client is opened. The anonymous user is saved in the service file together with the password.
You define pool connections in the service file using the following parameters:
~poollogin
~poolpassword
~poolclient
If these parameters are not defined in the service file, the ITS uses the values defined for the parameters ~login , ~password, and ~client.
