OPEN_RETRY - UDM Manager configuration option

Description

The OPEN_RETRY option provides a level of fault tolerance for the open command.

If UDM cannot establish a transfer session due to network error — because a remote Broker was not running or, basically, for any reason other than an invalid user name or password — UDM will wait a period of time (specified by the OPEN_RETRY_INTERVAL option) and then retry to open a session.

UDM will attempt to establish a session until it is successful or it reaches the retry limit (as specified by the OPEN_RETRY_COUNT option). If the retry limit is reached, UDM will stop attempting to establish a session and will return an error.
