The System INIT settings are the settings the BDE uses to start an application. This information is stored in the Windows Registry.
To display these settings:
1.Click the Configuration tab in the left pane and expand Configuration in the settings tree.
2.Expand System in the tree.
3.Expand INIT in the tree.
4.The settings appear on the Definition tab in the right pane.
In the following table, Parameter lists all the configurable system and network parameters, with their current values. When your BDE application is first installed, all values are set to their defaults.
Description briefly notes the purpose of the selected parameter.
To change a setting, highlight the desired parameter. Then replace its old value with a new value. When edits are complete, choose Object|Apply or click the Apply button to save the changes.
Parameter |
Description |
AUTO ODBC |
Set to TRUE to import installed ODBC drivers and datasources every time BDE is initialized. Default: FALSE. Note: Setting AUTO ODBC to TRUE is no longer recommended because of the Virtual configuration mode setting. For more information, see Options dialog box. |
DATA REPOSITORY |
The name of the active data dictionary. |
DEFAULT DRIVER |
Driver first tried when TYPE is FILE and the table name has no extension. Also, for files with a .DBF extension, specifies whether to use the dBASE or FoxPro driver. |
LANGDRIVER |
System language driver that defaults to the OEM driver appropriate for a country's version of Windows; for example, 'ascii' ANSI (DBWINUS0) for US workstations. |
LOCAL SHARE |
The ability to share access to local data between an active BDE application and an active non-BDE application. Set to TRUE if you need to work with the same files through both a BDE and a non-BDE application at the same time. (It is not necessary to set LOCAL SHARE to TRUE if you do not need to have both applications open at the same time.) Default: FALSE. |
LOW MEMORY USAGE LIMIT |
Maximum amount of low memory the BDE will attempt to use, in kilobytes. Default: 32. |
MAXBUFSIZE |
Maximum amount of memory for database data cache, in kilobytes. Can be any integer between MINBUFSIZE and 65,535 (inclusive). Must be a multiple of 128. Default: 2048. |
MAXFILEHANDLES |
Maximum number of file handles the BDE uses. Can be any integer ranging from 5 to 4096. High values improve performance but use more Windows resources. Default: 48. |
MEMSIZE |
Maximum amount of memory that BDE will use, in megabytes. Default: 16 MB. Maximum 205. Any number specified over 205 sets MEMSIZE to 205. |
MINBUFSIZE |
Minimum amount of memory for database data cache, in kilobytes. Can be any integer between 32 and 65535. Must be less than the total amount of RAM available to Windows. Default: 128. |
MTS POOLING |
Set to TRUE to enable MTS pooling, thus improving the initial connection time of opening a database. Default: FALSE. |
SHAREDMEMLOCATION |
Preferred address of shared memory manager. The shared memory manager and shared buffer manager load at a preferred address. If this address is used, the system can find a suitable address (first process only). If this address conflicts with another application, you might want to modify it. If the shared managers cannot be loaded into the default, or specified memory address, one attempt to allow the operating system to find a memory address is made. If a memory address if specified outside the boundry (below), the default is used. |
SHAREDMEMSIZE |
Maximum amount of memory BDE will use for shared resources, in kilobytes. Default: 2048 KB. Minimum: 2048 KB. If a value below 2048 is specified, 2048 will be used. File handles, drivers, and system, client and table objects are shared resources and SHAREDMEMSIZE should be increased when using many of these objects. |
SQLQRYMODE |
Method for handling queries to SQL data. Can be NULL, SERVER, or LOCAL. The SQLQRYMODE parameter appears only if a Borland SQL Link driver is installed. Default: NULL. |
SYSFLAGS |
Internal BDE setting. Do not modify. |
VERSION |
An internal setting that describes the current version of the BDE. Do not modify. |
