Error 631
Severity
21
Error message text
The length of %d passed to delete row routine for the row at offset %d is incorrect on the following page: %S_PAGE. The expected row length is %d. The offset should be no greater than %d.
This error may be caused by a hardware problem.
Explanation
This error occurs when Adaptive Server attempts to delete a row (via a direct delete or inherently through updating) from an index or data page by specifying the row offset and the row length, and the action fails because the specified values of the offset or row length did not match the actual values.
Error 631 can happen under the following conditions:
During normal processing, when Adaptive Server tries to delete the row specified by the error message.
During database recovery. Database recovery occurs:
During Adaptive Server start-up
When a load database or load transaction command is processed
Some potential causes of Error 631 are:
Data corruption during normal processing (for example, an operating system panic occurs, causing interruption in disk writes when using UNIX files for Sybase database devices). This may be due to a problem with Adaptive Server, the operating system, or hardware.
Hardware failure during loading or dumping.
Action
Error 631 is probably the result of a more serious underlying problem, and recovering from this error depends on when the error occurred. Follow the instructions in this section, selecting the correct set depending on whether the error occurred during normal processing or during database recovery.
If the Error Occurred During Normal Processing
Use the procedure in "How to Find an Object Name from a Page Number" in the Encyclopedia of Tasks chapter to identify which table and index correspond to the page number from the error message text.
If the object encountering the error is not a system table (a system table's object ID is less than 100), continue with step 3.
