This section contains information describing how to use the Oracle Net8 Assistant to configure advanced Names Servers tuning options.
Back to "Advanced Options"
Config Checkpoint File
Enter any valid filename to specify the name of the file used to checkpoint configuration settings. The filename is set by default to "ckpcfg.ora."
Region Checkpoint File
Enter any valid filename to specify the name of the file used to checkpoint domain data (all the database addresses in the region).
Log Directory
Enter any valid directory name to indicate the name of the directory where the log file for Names Server operational events are written. The directory name will default to an operating-system specific directory name.
Trace Directory
Enter any valid directory name to indicate where trace files from a Names Server trace session will be written. The directory name will default to an operating-system specific directory name.
Trace File
Enter any valid file name to indicate the name of the output file from a Names Server trace session. The trace file name will default to names.trace.
Make Trace File Unique
To specify a unique name for each trace file, click on the Make Trace File Unique button. This will allow multiple trace files to coexist. Each new trace file created will be appended with a unique string to identify it. For example, a trace file named "names.trc", will be appended to "names_01.trc" to identify it.
Miscellaneous Tuning Options
To specify miscellaneous tuning options:
Max Open Connections
Enter a number between 2 and 64 to specify the number of connections that the Names Server can have open at any given time. The value is generated as the value 10 or the sum of one connection for listening, five for clients, plus one for each foreign domain defined in the local administrative region, whichever is greater. Any operation which requires the server to open a network connection will use an already open connection if it is available, or will open a connection if not. Higher settings will save time and cost network resources; lower settings save network resources, cost time. The default value is calculated based on previously entered data.
Message Pool Start Size
Enter a number between 3-256 to specify the initial number of messages allocated in the server's message pool which are used for incoming or outgoing forwarded messages. The default value is set to 10.
Auto Refresh Expiration
Enter a time value between 60 and 1209600 seconds to specify the amount of time (in seconds) that the server will cache the addresses of Names Servers in other regions (for example, the root region) which have been obtained through a 'names hint'. When this time expires the Names Server will issue another query to other Names Servers in those regions to refresh the data.
Auto Refresh Retry
Enter a time value between 60 and 3600 seconds to specify the interval (in seconds) at which the Names Server will retry a refresh query if it initially fails.
