Parameter: PARTITION_SWITCH_TIMEOUT

Definition

The timeout in milliseconds for the detection of a failed partition switch. This timeout is for each partition.

Description

The timeout in milliseconds for the detection of a failed partition switch. When a partition is switched from an instance (rater or guider) to a new instance, the dispatcher waits for all the messages to be processed by the old instance. The old instance may fail to answer in a timely manner, blocking entirely the partition switch. As a consequence, the dispatcher forbids the new instance to start. The recommended value for this parameter is the typical timeout expected on SAP CC for processing a request (generally between 1,000 ms and 10,000 ms). A value of 0 for this parameter means that there is no timeout when a partition switch occurs. In this case, a partition switch may fail indefinitely.
