The minimum number of idle, or inactive, AppServer connections to maintain. Given sufficient AppServer resources, this setting allows the WSA Adapter, REST Management Agent, or the OpenEdge Adapter for Sonic ESB to always have a free connection available when a new request arrives, so the request does not have to wait for the adapter to locate and establish a new connection to service it. When the value of this property is greater than zero, the adapter uses its free time to pre-allocate network connections for the service connection pool.
