APAR status

  • Closed as program error.

Error description

  • -902 sqlcode and database marked bad as the result of an
    unexpected Lock conflict for an internal V lock.
    
    When two applications execute the same SQL statement with a
    REOPT setting in effect, V lock processing can result in an
    internal 'lock conflict' error which would result in a -902
    sqlcode and the database being marked bad. In order for this
    lock processing error to occur, the application hitting the
    error would have issued DDL in the current transaction
    

Local fix

  • 1) Do not use REOPT statements
    
    2) When using REOPT, do not have DDL statements within REOPT
    enabled statements.
