To configure the CRCN transaction, set the ES_XA_RECONNECT environment variable to a value that represents the delay, in seconds, between two monitoring sessions. CRCN retrieves this value. For example: ES_XA_RECONNECT=20
This causes CRCN to monitor the list of enabled resource managers every 20 seconds. When ES_XA_RECONNECT is set, CRCN is started at region initialization and begins monitoring as soon as it is active.
