SUMMARY

This article discusses the three most common error messages returned by the Microsoft Jet database engine 3.x that denote some form of corruption in the database. The article discusses what the messages mean and how to resolve the issue(s) causing the error.

MORE INFORMATION

The following errors typically denote some form of corruption in the database.

Error Number 3197:

Error message:
The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.
Cause/Problem:

This error typically occurs when a long value column (an OLE or MEMO data-type) has bad data stored in it. Long value columns are typically stored in a separate page from the page that the row is stored in. If a long value column is present in the table schema, the Jet database engine will attempt to read the long value page when reading the row of data. In order to read the long value page, there is a pointer in the row of data. This error is generated when the Jet database engine cannot properly read the long value page from the pointer present in the data row. When viewing a row that exhibits this behavior in Microsoft Access data-windows, the user will typically see the number sign (#) for the entire row.

Error Number 3343

Error message:
Unrecognized database format 'databasename.mdb'.
Cause/Problem:
This is typically caused when the Jet database engine was improperly shut down during the process of writing to disk.

Error Number 3015

Error message:
'databasename.mdb' isn't an index in this table. Look in the Indexes collection of the TableDef object to determine the valid index names.
Cause/Problem:
This error message is typically caused when there is an index missing on the MSysObjects table. This is typically caused if the repair process is aborted.

RESOLUTION

The Microsoft Jet database engine version 3.51 has an enhanced compact process designed to remedy the problems (if possible) described in the "More Information" section. The improved compact process now assumes all the functionality of the repair process, and therefore it is no longer recommended that you use the Jet database engine repair process.

NOTE: The Microsoft Jet database engine version 3.51 update is designed for Microsoft Access 97. You can run the compact utility on a database created in an earlier version of Microsoft Access; however, running the compact utility, "JETCOMP.exe", requires that Microsoft Access 97 be installed on your computer.
