Description:

SPR# RLBC6QXL6B - This fix introduces a control to change the Router's DNS Query time-out when dispatching messages to internet domains. Dispatching a message to a valid or invalid internet domain will normally take a fraction of a second. However, sometimes dispatching a message to an internet domain does not immediately fail in DNS. The DNS Query fails, then retries several times, with an increase in delays with each subsequent retry. This can take several seconds.

This fix adds support for a Notes.ini setting to control the number of DNS Query retries performed by the Router. For example: RouterDNSQueryRetryCount=1 specifies that the Router should only perform one retry attempt when an error occurs performing a DNS query. A nonzero value must be specified for this Notes.ini. If 0 is specified, the default of 4 retry queries will be performed. Note that the Router will delay for 1 second before attempting the first retry for a failed DNS query, and this time is doubled for each retry attempt of the same query.

 

Please note: this fix is for the Unix platform only and does not apply to Windows.





UI equivalent:
There is no kown UI setting for this notes.ini variable. But you can specify this setting in the notes.ini settings tab of the configuration settings document.
