File corruption in Jet file-sharing database system

Microsoft Jet database is a file-sharing database system. A file-sharing database system means that the processing of the file occurs at the client. In order to allow multiple users to share the same file over the network, Jet Database Engine uses a Lock file (.ldb) to synchronize the read write operations of the database. When a file-sharing database, such as Microsoft Jet, is used in a multi-user environment, multiple client processes use file read, file write, and file locking operations on the same shared file across a network.

If a process cannot be completed, the file may be left in an incomplete state or in a corrupted state. When you use Microsoft Jet in high-stress applications such as Microsoft Internet Information Server (IIS), you may experience any one of the following problems:

• Database corruption
• Stability issues, such as IIS crashing or locking up
• Sudden failure or persistent failure of the driver

Opportunistic locking may increase the risk of Jet database corruption when a file is shared by two or more clients on a network file server. Most of the times, the network problem leave the Access database in a “Suspect” state and cause corruption. In all of these situations, you need to repair your Access database in order to use it.

If you disable opportunistic locking, this may adversely affect the performance of other applications. To get rid from this solution you can install latest service pack provided by Microsoft or latest Jet hotfix service pack. Problems also occur when you restart the server after you apply new software or you apply a service pack or a hotfix, and you forget that the Microsoft Jet database is currently shared on the server. In this situation you need a tool called access recovery tool which have capability to repair your Access database.

These softwares work on the header of the corrupted file and repairs and restores it without changing the original contents of the database files. Stellar Phoenix Access Repair is best data recovery software to restore your corrupted database by fixing bugs and errors. Using this utility you easily repair forms, queries, table, modules and macros. Stellar Phoenix scans for corrupted files to repair and restore it to a default location or a user specified location on the hard drive. It is compatible with all file versions of Microsoft Access such as Access 97, 2000, 2002, 2003 and 2007.

Solve Network or Disk Error in Microsoft Access 2.0

Higher version of MS access has lots of new features which makes it user friendly. But sometime when we use Access 2002 with a data file on the network drive, your data may seem to disappear. You will see that access is still running but all the forms, queries, tables, etc are no longer listed in the database window and open forms no longer have any data in the fields and no longer function.

This is usually accompanied by a "Disk or Network Error" message or a message that the form cannot be found. One more situation is the database does not appear to be damaged and opens fine if you close and reopen Access. The user was able to open a network based .mdb file, but when you tried to click on a switchboard button they received the following error message: "Disk or network error." When you try to open an Access 2.0 database file in Microsoft Access 2000 or Access 2002, you may get this network error.

In this situation how you will workaround with this error. There are many resources that deal with this error; I can provide you some of them. It may possible that mdb file has many linked tables that were using a static network path. In this scenario we need to have the MS Office XP disk to install the 'Linked Table Manager'. Once this was installed, you can update all linked tables to use the UNC path and not the static path.

The problem can occur when the data source is opened under the Microsoft Internet Information Server. As Jet creates a temporary file when the engine is started so we have to check that the TMP/TEMP directories were set properly. Define a TMP or TEMP environment variable and assign the variable to an existing folder. Or you can install latest service pack of Microsoft jet 4.0 which fix this error. Sometimes this error may come due to database corruption, in this situation you need access recovery utility to repair your damaged database as Microsoft has been provided compact and repair utility but it has some limitation so it doesn’t work with every error.

Repair operation on Microsoft access cab operate by compact and repair utility but it will not help in this situation. So access database repair can be done with the help of special third party access repair softwares. You must use the best access repair utility as the databases provide a large source of information to most of the companies. Stellar Phoenix access recovery software is one of best utility available over internet to repair your critically damaged or corrupted database. It performs thorough scan of the damaged access files; rectifies and restores the Access files with their Tables, Queries, and Reports intact even it works on password protected file.

Microsoft Access can't find the database file” Error in Ms Access

Some predefined action is an efficient way for programming in any programming language. When we talk about MS access we consider Macros as predefined actions.. Macros can perform a number of the common tasks same as Visual Basic code to perform in MDB file. As MDB and macro has some limitations so we prefer module and MDE files over macros and MDB file. Now we should know about MDE files. MDE file format allow you to limit database users from modifying database application that make your data more secure. You can’t edit, delete or modify MDE files. The MDE format allows you to store the same information that is contained in MDB files except that the underlying VBA are pre-compiled and stored in machine code. We can’t contain macros because macros do not provide error-handling capabilities. For converting your MDB files to MDE files, we recommend you to split your database and convert front-end to MDE format. An MDE files compiles all modules, remove all source code and make your database more compact and secure.

Converting a MDE file to MDB file has some limitations. Although it protects your application from modification or theft, If you want modify your MDE file then you must convert in MDB files. In process of converting MDB to MDE file we lost our macro. We always recommend you to make backup of your MDB file before converting it into MDE files. Sometimes you get common error messages

“Microsoft Access can't find the database file '.MDB.' Make sure you entered the correct path and file name.” If you have your operating system configured to hide MS-DOS file extensions, when you try to export a Microsoft Access 97 object to an MDE file you may receive above message. There is strong change to loss and corruption of your MDE files. For this you have to recover your database file macro so that you can convert MDE files to MDB files. If you have large no of macros we have nice solution for you to repair access file by recovering macros.

Go to macros menu on the tools menu in access. From here you can regenerate some VBA code from the macros choose “convert macros to visual basic”. After this you have to edit VBA code for compiling.

-->Create and MDB replica or carbon copy of your MDE file using tool menu.

-->Make MDB replica to MDB file by choosing recover design master.

-->Choose MDB files and run Stellar Phoenix Access Recovery Software.

-->Now you can import everything from MDB file.

-->Search for macros in recovered MDB file and highlight them now Highlight each macro in the recovered database and choose “Convert Macros to Visual Basic” from the Macros menu on the Tools menu.

With the help of above method and Stellar Phoenix Access Repair software you can recover your macros from MDE files without loss of your important database. This software is easy to use and compatible with all version of access. It proves you fast recovery and supports file versions of MS Access including Access 2000, 2002, 2003 and 2007.
