Adjusting the requests to resend messages

When a message is missing from a sequence, the SQL Remote Message Agent (dbremote) waits a specified number of polls before requesting that the missing message be resent. The number of polls that the SQL Remote Message Agent (dbremote) waits is referred to as its patience. By default, the SQL Remote Message Agent (dbremote) has a patience of 1.

If the SQL Remote Message Agent (dbremote) has a patience of 1 and it expects to receive message 6 but it receives message 7, the SQL Remote Message Agent (dbremote) takes no action. Instead, the SQL Remote Message Agent (dbremote) waits for the results of the next poll. If after the next poll, Message 6 is still missing, then the SQL Remote Message Agent (dbremote) issues a resend request for Message 6.
