Error description

  • Duplicate Query Variable entries created in database during
    process instance migration
    .
    During process instance migration, duplicate entries can get
    created in BPEDB table QUERYABLE_VARIABLE_INSTANCE_T. This is
    observed when the migration instance contains a correlation set
    as well as query properties. Duplicates are characterized by
    same PIID and VARIABLE_NAME/PROPERTY_NAME. As a result of the
    data duplication query table queries can yield the following SQL
    error:
    .
    DB2 SQL Error: SQLCODE=-811, SQLSTATE=21000, SQLERRMC=null,
    DRIVER=4.12.55
    .
    The error indicates more than one result returned in a scalar
    fulselect query.
    

Local fix

Problem summary

  • The entries in the QUERYABLE_VARIABLE_INSTANCE_T table are
    properties of BPEL process variables that
    are evaluated when variable is updated in the database. The
    problem did happen because this
    evaluation was triggered before the existing entries of this
    process instance where migrated to the
    new version. This resulted in new entries and finally to
    duplicate entries after the already
    existing entries where migrated.
    

Problem conclusion

  • The problem was fixed by changing the order in which the
    entities that belong to the process
    instance are migrated
