Use the Reset Timestamps command from the Operation menu or click the Reset Timestamps toolbar button, to reset the timestamps in your database files. (For details, see "Resetting Timestamps", in Chapter 3.)
Use this command with care and only when it is necessary to override timestamps when files have been legitimately replaced.
To reset data file timestamps
Select the Reset Timestamps command from the Operation menu or click the Reset Timestamps toolbar button. (You cannot reset timestamps if database recovery is required.) The Select Files for Timestamp Reset dialog is then displayed.
Select the required database file or files whose timestamps you want to reset, by performing one of the following actions.
Select the files from the Database Files list box. The selected files are highlighted. When you have selected all of the files that you require, click the Add button.
To select all of the database files, click the Add All button.
Select each file by double-clicking the file in the Database Files list box.
The selected file names are moved to the Selected files list box.
To remove database files from the Selected files list box, perform one of the following actions.
Select the files for removal from the Selected files list box. When you have selected all of the files for removal, click the Remove button.
To remove all of the files from the Selected files list box, click the Remove All button.
Select each file by double-clicking the file in the Selected files list box.
The selected file names are moved back to the Database Files list box.
If you want to look for system database files, check the Show System Files check box. (By default, system files are not displayed for selection; that is, user schema files only are displayed when you first access this dialog.)
If you do not want user schemas displayed for selection, uncheck the Show User Schema Files check box. (By default, user schema files are displayed for selection when you first access this dialog.)
When your list of selected files is complete, click the OK button to start the operation. Alternatively, click the Cancel button to abandon your selections.
When the operation is finished, the following message is displayed in the running report.
