The Tuning tab enables you to set tuning options for a running Oracle Names server. The values you specify remain valid only for the current session.
Cache Checkpoint Interval
Enter a time in seconds to specify the time interval at which an Oracle Names server will write a copy of the data it has obtained from remote regions to a local cache checkpoint file, which has a default of ckpcch.ora. In the case of a failure of the Oracle Names server, information that had been cached from other Oracle Names servers and their time-to-live (TTL) values will remain.
Minimum Value: 10 seconds
Maximum Value: 3 days
Statistics Reset Interval
Enter a time value to specify the time during which statistics collected by an Oracle Names server will accumulate.
Minimum Value: 10 seconds
Maximum Value: 3 days
Statistics Log Interval
Enter a time value to specify the time between statistical dumps to the log file, which has a default of names.log. The value must be smaller than the Statistics Reset Interval. Otherwise, statistics will not be logged.
Minimum Value: 10 seconds
Maximum Value: None
Auto Refresh Interval
Enter the retry interval period in which the Oracle Names server will retry when the auto refresh query fails.
Minimum Value: 1 minute
Maximum Value: 1 hour
Auto Refresh Expiration Period
Enter the expiration period for when an Oracle Names server should try to obtain a remote region's Oracle Names servers address information. The Oracle Names server contacts all the Oracle Names servers on its domain hint list to obtain the latest address information. The address information is saved to the local Oracle Names server cache checkpoint file, which has a default of ckpcch.ora.
At the end of the expiration period, the Oracle Names server issues a query to the Oracle Names servers in the domain hint list.
Default: 60 seconds
Minimum Value: 60 seconds
