Parameter
enque/con_timeout
Short text
Timeout for establishing connection to standalone enqueue server
Parameter Description
If you are using the standalone enqueue server, every work process creates a separate network connection. If this fails, the process attempts to create the connection again after the period of time specified by this parameter has passed. It attempts this enque/con_retries times.
If the standalone enqueue server is not available at any time, the process is blocked for this time.
If the enqueue server is still not reached after the timeout has expired, the application receives the “SYSTEM_FAILURE” exception, which may not be desired. When setting these two parameters, you therefore need to consider how long you want to have the work processes blocked (all work processes might be occupied) and how long you allow the enqueue server and the HA software for a failover.
enque/con_timeout should not be too large, so that the work processes can connect to the enqueue server as soon as it is available again. However, it should also not be too small so that you do not flood the network with connect attempts during the period when the enqueue server is not available.
