Statistics Options dialog box – DataPage option
When you select the Datapage option, the Statistics Options dialog box changes to add the following items:
Database Directories - This list shows the different directories in which a database application could reside. You can add or delete directories from this list. A maximum of ten directories per STATS/ON command can be selected to which statistical information can be sent.
Add Directory to List - Displays the Add Directory To List dialog box that lets you specify a directory containing a database you want to use with DataPage:
Add Directory to List
When the dialog box appears, you can either type the pathway containing the database in the Statistics directory to add box, or click the ... button to browse to the directory. Then click OK. to add the specified directory into the Database Directories list.
Use the Remove Previous-Used Directory to remove previously defined directories.
Delete Directory from List - Deletes the selected database directory from the Database Directories list.
Delete Current Stats File - Deletes your xstats11.tmp file.
For details on the locations of PC-DMIS files, see "Understanding File Locations".
Update Database Now - Updates your database application with statistical data gained from your current measurement routine. Simply click this button and follow the instructions on screen. This uses DPUPDATE.exe to update the database.
Upon successful execution of a measurement routine, selected Dimension and tracefield information is stored within a file named XSTATS11.tmp. The information in this file can then be transferred to a different directory, printed out, or sent to a database application.
If a database application is unavailable, PC-DMIS displays a message informing you that it can't find the update executable (for the DataPage application, this is DPUPDATE.exe) to load XSTATS11.tmp into the database.
You must run PC-DMIS with administrator privileges for DPUPDATE.exe to work.
DataPage Variable Name - This area indicates whether the dimension name or feature name will be used to identify entries in DataPage. The maximum length of the name is 10 characters. To choose either the dimension name or the feature name, select the Use Dimension Name option or the Use Feature Name option.
Do Control Calculations - Contains options to indicate whether the control calculations that take place within Datapage should be used. Selecting the On option performs the out of tolerance control calculations. Additionally, it commands the DataPage statistics update program (DPUPDATE) to perform the control calculations and set the part/variable and in/out of tolerance/control indicators in the database. You can monitor this database using DataPage's Monitor mode by turning on the part/variables colors (red/yellow/green) based on those calculations. For additional information, see the help file that ships with DataPage's Monitor mode application.
To turn control calculations on or off simply select either the On or the Off option. The default setting is Off.
Read Lock - Determines the maximum number of seconds that PC-DMIS will wait for database access when reading. The default value is 10 seconds.
Write Lock - Determines the maximum number of seconds that PC-DMIS will wait for database access when writing. The default value is 20 seconds.
Memory Pages box - Determines the number of 4K pages to reserve for database tables when opening a database. The minimum (and default) number of pages that can be open is four.
