Summary
By introducing the following properties, this improvement provides a method to control the SAP .NET Connector (NCo) connection pool parameters at a finer granularity, and override the default values that are set by the adapter based on the WCF connection pool configuration properties. These properties can be configured on the Binding tab of the WCF-SAP Transport Properties under a new section that's named SAP NCo Connection Pool. They include the following:
-
NCoPoolSize: Corresponds to the POOL_SIZE SAP NCo client connection parameter. It represents the maximum number of SAP NCo connections that are kept in the NCo connection pool. By default, it is set to the same value as the MaxConnectionsPerSystem property in the Connection section.
-
MaxPoolWaitTime: Corresponds to the MAX_POOL_WAIT_TIME SAP NCo connection parameter. It represents the maximum amount of time in milliseconds that an NCo connection request waits after the peak connection limit is reached. By default, it is set to 0 milliseconds.
-
UseNCoConnectionPoolSettings: Indicates whether the values that are assigned to NCoPoolSize and MaxPoolWaitTime should override the default values that are set by the adapter based on the WCF connection pool configuration properties. By default, it is set to False. If set to True, the new SAP NCo connection pool properties override the default values that are set by the adapter, and the IDLE_TIMEOUT and IDLE_CHECK_TIME NCo client parameters will be set to the IdleConnectionTimeout value.
