Configure Server: Adv.

The Advanced tab enables you to configure advanced tuning options for the Oracle Names server.

Cache Checkpoint File

Enter the directory path name and the file name for the client cache checkpoint file. This file contains cached information about the names and addresses of Oracle Names servers in the local administrative region, as well as information in remote regions. The default file name is ckpcch.ora and the default path is $ORACLE_HOME/network/names on UNIX platforms and ORACLE_HOME\network\names on Windows NT.

Config Checkpoint File

Enter the directory path name and the file name for the configuration checkpoint file. This file contains information about the Oracle Names server, similar to configuration settings stored in the names.ora file. This file is used in case the Oracle Names server shuts down unexpectedly. The default file name is ckpcfg.ora and the default path is $ORACLE_HOME/network/names on UNIX platforms and ORACLE_HOME\network\names on Windows NT.

Region Checkpoint File

Enter the directory path name and the file name for the region checkpoint file. This file is a local copy of data that is stored in the administrative region. The default file name is ckpreg.ora and the default path is $ORACLE_HOME/network/names on UNIX platforms and ORACLE_HOME\network\names on Windows NT.

Log Directory

Enter the directory path to which log files will be written. The default is $ORACLE_HOME/network/log on UNIX and ORACLE_HOME\network\log on Windows platforms.

Log File

Enter the name of the log file for the Oracle Names server. The default name is names.log.

Trace Directory

Enter the directory path to which trace files from a Oracle Names server trace session will be written. The default directory is $ORACLE_HOME/network/trace on UNIX and ORACLE_HOME\network\trace on Windows platforms.

Trace File

Enter the name of the trace file for the Oracle Names server. The default name is names.trc.

Make Trace File Unique

Choose this option to create unique names for each trace file. A process identifier is appended to the name of each trace file, so that several trace files can coexist. Clear this option if you do not want unique trace files created, and you want all trace information stored in the same trace file.

Miscellaneous button

Max Open Connections | Enter a number between 2 and 64 for the number connections the Oracle Names server can have open to other Oracle Names servers at any point in time. Default: 10 connections Minimum Value: 2 connections Maximum Value: 64 connections Tip: The connections that remain open at the same time save time and cost network resources. A lower value saves network resources and costs time.
Message Pool Start Size | Enter a number between 3-256 for the initial number messages to allocate in the Oracle Names server's message pool. Default: 10 messages Minimum Value: 3 messages Maximum Value: 256 messages Tip: The higher the number, the more resources the Oracle Names server will use, but the faster it will run.
Auto Refresh Expiration Period | Enter values in the fields 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: 3 days
Minimum Value: 1 minute
Maximum Value: 14 days
Auto Refresh Retry Interval | Enter values in the fields for how often the Oracle Names server will retry contacting Oracle Names servers in the domain hint list when the auto refresh query fails. Default: 3 minutes Minimum Value: 1 minute Maximum Value: 1 hour
