1958942 - Error: "Assertion failed: 123456" / SQLCODE -301 "Internal Database Error" - Handling an Assertion Failure


  • During start-up or during operation of the SAP SQL Anywhere database, there is an erroneous operating condition encountered and an error message is printed to the database console log:

    *** ERROR *** Assertion failed: ###### (x.x.x.xxxx)
    Error message follows with information about the cause of the assertion.

    The assertion number is a six-digit number, and the numbers following the assertion number in brackets will indicate the version and build of the SQL Anywhere database server that asserted. Details about the assertion are provided in a text line following the error.

  • A client connection that is already connected to the database or attempts to connect to the database may also see the error:

    Internal database error "Assertion failed: 123456 (xx.x.x.xxxx)" -- transaction rolled back
    SQLCODE=-301, ODBC 3 State="40W01"

    No other work may be performed on the database server and all further SQL commands will result in the reported client error.

  • At the time of the assertion message, the SQL Anywhere database server will also produce a diagnostic .DMP file and .CRASH_LOG file in the SADIAGDIR environment variable's file path with the file name prefix:


    Where 'SA1X' is the major version of SQL Anywhere, 'YYYYMMDD' is the date on which the assertion occurred, the 'HHmmss' is the time of day the assertion occurred and 'pid' is the Process ID of the crashing process.

    Running the Support Utility (dbsupport) with 'dbsupport -lc' may list this same entry as an outstanding crash entry to be submitted to SAP Support.
