The Tuning tab allows you to set tuning options for an Oracle Names server.

Cache Checkpoint Interval:

Enter a time value to specify the time interval at which an Oracle Names server will write a copy of the data it has obtained from foreign regions to a checkpoint file. In the case of a failure of the Oracle Names server, information that had been cached from other Oracle Names servers and their TTL values (how long that information is valid for) will remain.

Statistics Reset Interval:

Enter a time value to specify the time during which statistics collected by an Oracle Names server will accumulate. The default value of 0 will cause statistics not to reset.

Statistics Log Interval:

Enter a time value to specify the time between statistical dumps to the log file. The default value of 0 will disable logging. If this statistic is used, the value should be smaller than the statistics reset interval (otherwise nothing will get logged).

Auto Refresh Interval:

Enter the retry interval period in which the Oracle Names server will wait between attempts to contact the Oracle Names servers on its hint list.

The Oracle Names servers, on startup, contacts all the Oracle Names servers on its domain hint list. Shortly before their information expires (based on the TTL values passed to the local server), the local Oracle Names server tries to reconnect to refresh its information so it can continue to forward requests to the Oracle Names servers on its hint list. This value is between 60 and 3600 seconds, and should be shorter than the value for Auto Refresh Expiration. Default is 180 seconds.

Auto Refresh Expiration Period:

Enter the expiration period that will tell the Oracle Names server how long to keep trying the remote Oracle Names server before stopping and using that hint. An Oracle Names server, on startup, contacts all the Oracle Names server on its domain hint list. Shortly before their information expires (based on the TTL values passed to the local server), the local Oracle Names Server tries to reconnect to refresh their information so it can continue to forward requests to the Oracle Names servers on its hint list. This value is between 60 and 1209600 seconds, and should be longer than the value for Auto Refresh Retry. Default is 600 seconds.
