Issue:

ReliaSoft's Xfmea Standard and RCM++ software products work with with standard databases using the Microsoft Access file format in the back end for storing analysis data.. These database and library files (*.rx4 and *.lb4) will be subject to the same limitations and vulnerabilities as any other Access database. As described in the Microsoft publication at http://support.microsoft.com/kb/283849/EN-US/, "it is not possible to reliably prevent any and all database corruption." Database corruption may be the result of factors outside of the control of the Xfmea/RCM++ software, such as faulty network hardware, an unexpected "crash" of your PC or a network interruption.

If your entire Xfmea Standard or RCM++ database becomes corrupted, you will receive the message "Unable to open this database" when you try to open the database and the message "The selected database is read only and cannot be compacted" when you try to compact and repair the database.

Note: If only certain items in your database are corrupted, but you are still able to open the database, you may be able to remove the corruption. Please read Technical Support document # 20015, which provides instructions for doing so.

Solution:

Please contact ReliaSoft's Technical Support via phone, fax or e-mail and provide as much information as possible about exactly what you were doing when the corruption occurred. Whenever possible, please provide a copy of the corrupted file. In some cases, ReliaSoft may be able to provide assistance with salvaging some or all of the affected data. However, in many cases, the best recourse may be to restore the latest backup from before the corruption occurred.

In addition, please read Technical Support document # 40010, which presents some recommendations for standard precautions that users can take to protect against corruption and reduce the impact of the data loss if corruption is unavoidable.
