Using the Verify Checksums Command

Use the Verify Checksums command from the Operation menu to perform a checksum analysis of your backed up database files or your restored system to verify that the files have not been corrupted by a hardware or environmental problem during the backup or restore process.

We recommend that you perform a checksum analysis of any backup that has been moved across media, especially if transferred across a network.

To verify checksums

Select the Verify Checksums command from the Operation menu. The Select Directory dialog, shown in the following image, is then displayed.
In the Directory combo box, select the directory containing your backed up or restored database files from the combo box list, or specify the valid path in the text area of the combo box.

The list portion of the combo box lists up to the last 10 backup paths and the last 10 database paths, to enable you to select the directory that you require.

If you are unsure of the directory, click the adjacent browse button (indicated by the … points of ellipsis symbol) to display the common Browse for Folder selection dialog that enables you to select the path in which your backed up or restored files are located.

The path must exist. If you have previously run the checksum verification in the current JADE release, the path that you used the last time the operation was performed is displayed in this text box.
Click the OK button. Alternatively, click the Cancel button to abandon your selections.

The checksums verification operation is driven from the backupinfo file in the specified backup directory or the restoreinfo file in the database system directory. Each file whose checksum is verified is displayed in the running report in the JADE Database utility window as the analysis is performed.

While the operation is running, a progress dialog is displayed that enables you to monitor the progress of the operation. You can abort the run, by clicking the Cancel button.

When the operation is finished, the progress dialog is closed and the following message is displayed in the running report.

<<Checksum verification complete>>

Detailed results of the operation are written to the checksum.log file, which you can view by selecting the checksum.log command from the View submenu displayed when you select the View Logs command. (For details, see "Viewing Log Files", later in this chapter.)
