Configure Server: Advanced

Configure Server: Advanced

The Advanced tab allows you to configure advanced tuning options for an Oracle Names server.

Cache Checkpoint File:

Enter any valid file name to specify the name of the operating system file to which the Oracle Names server writes its foreign data cache. This is the data that it receives from other servers and then can use to answer other client requests for a short time (length of time determined by the Oracle Names server from which foreign data was received). The file name is set by default to CKPCCH.ORA.

Config Checkpoint File:

Enter any valid filename to specify the name of the file used to checkpoint configuration settings. This file will store all the configuration settings of the Oracle Names server in case the Oracle Names server goes down unexpectedly. The file name is set by default to CKPCFG.ORA.

Region Checkpoint File:

Enter any valid file name to specify the name of the file used to checkpoint region data. This is either a copy of all the information in the region database or the store of all the Oracle Names Server’s information on its region if it is not using a region database. The filename will default to CKPREG.ORA.

Log Directory:

Enter any valid directory name to indicate the name of the directory where the log file for Oracle 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 Oracle 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 an Oracle Names server trace session. The trace file name will default to NAMES.TRC.

Make Trace File Unique:

Click this option to specify a unique name for each trace file. This allows 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 button:

Click this button to configure the following:

Max Open Connections:

Enter the number of connections an Oracle Names server can have open to other Oracle Names servers at any point in time.
The connections that remain open at the same time will save time and cost network resources. A lower value will save network resources and cost time. The default value is calculated based on previously entered data. If you wish to change the value, enter a number between 2 and 64.

Message Pool Start Size:

Enter how many connections you want ready for use in the Oracle Names server.
Each connection process takes memory, but to create connection processes as you need them takes time. The higher the number, the more resources the Oracle Names server will use, but the faster it will run. Enter a number between 3-256 to specify the initial number of messages allocated in the server's message pool. The default value is set to 10.

Max Open Connections:

Enter the number of connections an Oracle Names server can have open to other Oracle Names server at any point in time.
By letting more connections remain open at the same time, will save time and cost network resources; a lower value here will save network resources, cost time. The default value is calculated based on previously entered data. If you wish to change the value, enter a number between 2 and 64.

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 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.

Auto Refresh Retry Interval:

Enter the retry interval period in which the Oracle Names server 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 their 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.

Max Open Connections:	Enter the number of connections an Oracle Names server can have open to other Oracle Names servers at any point in time. The connections that remain open at the same time will save time and cost network resources. A lower value will save network resources and cost time. The default value is calculated based on previously entered data. If you wish to change the value, enter a number between 2 and 64.
