What are the Common Causes of DBF File Corruption in Visual FoxPro
?
Visual FoxPro is a popular data-centric procedural and object-oriented programing language and RDBMS (Relational Database Management System), developed by Microsoft Corporation. The application stores your significant data in DBF (Database File) file. You can retrieve data from DBF file using queries. Under some circumstances, the DBF file gets damaged and you cannot access data from it. It causes serious data loss situations and requires DBF Recovery to be resolved.
There are numerous reasons, which can result into Visual FoxPro database file corruption. Some of the common reasons of data corruption issues in Visual FoxPro are as given below:
Improper termination of Visual FoxPro while manipulating the data- This problem can occur due to internal application inconsistency errors, fatal exception errors, page faults, power surges, system crash, and voltage spikes.
Virus Infection- Viruses are one of the biggest threat to your data. You should regularly scan your system using an updated Anti-virus application.
Data storage components- You should regularly check your hard drive for fragmentation and errors.
Conflicting applications- Third-party software like screen savers and Anti-virus may cause several conflicts with the Visual FoxPro, which can lead to DBF corruption.
Faulty or substandard network components- Since Visual FoxPro application handles data too quickly, it could stress your network. Such components might include network interface cards, hubs, switches, network drivers, and cables.
File locking problems- If one DBF file user performs any operation, which locks the memo file of table, and second DBF user tries to open same database table and then access memo field, second user might open memo file with wrong blocksize. It results into the memo file corruption.
Service packs and network settings- You should make sure that the database servers are using the latest service packs. Also check the settings, such as disk caching, on client computer. You can also try switching the drivers of network clients.
If you run across any of the above situations, the DBF file becomes completely unusable. If corruption is severe, you can not even open the Visual FoxPro application. In such cases, DBF file repair tools are required to extract inaccessible data.
