Polling interval

By default, a Message Agent running in continuous mode polls one minute after finishing the previous poll, to see whether new messages have arrived. You can configure the polling interval using the -rd option.

The default polling interval from the end of one poll to the start of another is one minute. You can poll more frequently using a value in seconds, as in the following command line:

dbremote -rd 30s

Alternatively, you can poll less frequently, as in the following command line, which polls every five minutes:

dbremote -rd 5

Setting a very small interval may have some detrimental impact on overall system throughput, for the following reasons:

In general, you should not use a very small polling interval unless you have a specific reason for requiring a very quick response time for messages.

Setting larger intervals may provide a better overall throughput of messages in your system, at the cost of waiting somewhat longer for each message to be applied. In many SQL Remote installations, optimizing turnaround time is not the primary concern.
