Using the network application developed by Access database, there is a possibility of "real-time error 3043, disk or network error" in many cases, thereby disruption of the Access database varying degrees. First, cause "real-time error 3034, disk or network error". Hardware environment: It includes a network card with individual needle damage; whether the network cable is destroyed or whether the capacity of the network cable meets the requirements of the network application (such as the network application requires 100m network, and only 10M network); whether the network connector is strict Or if the needle of the network connector has an individual damage; if the Hub is working properly; the server configuration does not meet the requirements of the network application (generally lower than the network application requirements). 2. Software Environment: It includes the "Event Viewer" of the NT operating system, checks if there is a serious error and warning error, which affects the data read and write error; early WIN95 or WIN98; non-standard version WIN95 or WIN98. 3. The ACCESS database itself is a fatal point: the read and write mechanism of the Access database is instantaneous, that is, read the data table at a time point or simultaneously writes the data table, if the read-write data table exceeds a certain extreme value point, at this time Data read and write channels are destroyed. From this point, it can be seen that the network application developed by Access database cannot avoid "real-time error 3043, disk or network errors". Second, how to prevent "Real Time Error 3043, Disk or Network Error" seriously damage ACCESS database When a "Real Time Error 3043, Disk, or Network Error" appears in a network work site, you can avoid the Access database seriously Destruction, while ensuring that the database of other network works sites will not be lost: the first step, the "Real-Time Error 3034, Disk or Network Error" network work site does not first determine the exit network application system; second step, the other has not appeared "Real-Time Error 3034, Disk or Network Error" network workshop saves the dated data, then exits the network application system; third step, "Real-Time Error 3034, Disk or Network Error" network work site determination final quit Network application system. Third, how to fix the destroyed Access database, as described above, the general Access database will not be severely damaged. First use the Access database itself to repair the damaged database, such as repairing unsuccessful, available: First use the Access database tool to create an empty database, then use the Access database tool to get the external data in the database. All the original data and data structures of the query are imported into the established empty database, followed by compressing the imported database, finally fixing its database, replacing the original database with a repair database.
