Resetting Timestamps

Use the JADE Database utility Operation menu Reset Timestamps command to override file timestamps after installing new system or user-defined schema files. (For details, see "Using the Reset Timestamps Command", in Chapter 1.)

When you upgrade a runtime-only installation of JADE at a site (when only methods or form definitions but no structures have been changed), if you do not reset the database file timestamps first, the database reports an error on start up as the file timestamps do not match those in the control file.

Use the Reset Timestamps command with care and only when it is necessary to override timestamps when files have been replaced (for example, when deploying a new or patched release of a JADE application).

You cannot reset timestamps if database recovery is required.

To automate the process of resetting timestamps when replacing database files in a runtime deployment environment, you can execute the jdbutilb batch JADE Database utility executable program. (For details, see "Running the JADE Database Utility in Batch Mode", in Chapter 1.)
