Changing the Configuration Settings

What are the configuration settings?

The configuration settings in Express Configuration Manager control and define the behavior of Personal Express in many ways. For example, you can specify the search path for database files, the Personal Express identifier for SNAPI clients, the port number for XCA clients, and so forth. Default values are provided for all the configuration settings.

The configuration settings are on different tabs in the Edit Settings dialog box of Express Configuration Manager. The following table outlines the tabs that are available.

Tab	Description
Drive	There are no settings on this tab. Personal Express uses the Windows drive settings.
Exceptions	The settings on this tab control how Personal Express handles exceptions that may occur within Express sessions.
File I/O	The settings on this tab control I/O activity and specify the paths of files that are used by Personal Express.
Identifiers	The settings on this tab specify identifiers that are used by the transport layer encapsulated by SNAPI or XCA.
Locale	The settings on this tab specify how Personal Express maps single-byte characters that it sends to and receives from foreign character sets.
Memory	The settings on this tab control how Personal Express manages memory.
Paging	The Express Paging Manager manages a shared cache of database pages in memory. You can use the settings on the Paging tab to tune the performance of the Paging Manager.
Process control	The settings on this tab control how long Personal Express may take to start up or shut down before timing out.
Security	The setting on this tab controls whether or not Personal Express can use the SHELL command.
Session	The settings on this tab control session-specific behavior.

When to change the settings

In most cases, you will want to put Personal Express into use with the default settings and adjust them only after you have identified a particular area that needs improvement.

You also need to change some settings when you install both Personal Express and Express Server on the same Windows NT computer. For more information, see "Configuring Personal Express When Installed with Express Server".

Applying new configuration information

The configuration settings take effect when Personal Express starts. To apply the new settings, restart Personal Express. For more information on restarting Personal Express, see "How to Start, Stop, and Pause Personal Express".

Where are the configuration parameters stored?

Express Configuration Manager stores the configuration parameters for Personal Express in the Windows Registry.

Important: Oracle Corporation recommends that you always use Express Configuration Manager to modify the configuration information for Personal Express.
