Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

DESCRIPTION
The DNSServiceCreateConnection() function allows the creation of a connection to the mDNS daemon in order to register multiple individual records. The DNSServiceRegisterRecord() function uses the connection created by DNSServiceCreateConnection() to register a record. Name conflicts that occur from this function should be handled by the client in the callback. The DNSServiceAddRecord() call adds a DNS record to a registered service. The name of the record is the same as registered service name. The RecordRef argument to DNSServiceAddRecord() points to an uninitialized DNSRecordRef. After successful completion of DNSServiceAd- dRecord(), the DNS record can be updated or deregistered by passing the DNSRecordRef initialized by DNSServiceAddRecord() to DNSServiceUp- dateRecord() or to DNSServiceRemoveRecord(). The DNSServiceUpdateRecords() call updates the DNS record of the registered service. The DNS record must be the primary resource record registered using DNSServiceRegister() or a record added to a registered service using DNSServiceAddRecord() or an individual record added via DNSServiceRegisterRecord(). The DNSServiceRemoveRecord() call removes a record that was added using DNSServiceAddRecord() or DNSServiceRegisterRecord(). The sdRef argument points to DNSServiceRef initialized from a call to DNSServiceRegister(). If the sdRef argument is passed to DNSSer- viceRefDeallocate() and the service is deregistered DNS records added via DNSServiceAddRecord() are invalidated and cannot be further used. The flags argument is currently ignored and reserved for future use. The rrtype parameter value indicates the type of the DNS record. Suit- able values for the rrtype parameter are defined in <dns_sd.h>: kDNSServiceType_TXT, for example. The rdata argument points to the raw rdata to be contained in the resource record. The ttl value indicates the time to live of the resource record in seconds. A ttl value of 0 should be passed to use a default value.
RETURN VALUES
The DNSServiceCreateConnection function returns kDNSServiceErr_NoError on success. Otherwise, an error code defined in <dns_sd.h> is returned to indicate the specific failure that occurred.
