![]() APAR status Closed as program error. Error description Customer may use their own DB2DataStoreHelper class that extends IBM WebSphere's DB2DataStoreHelper class in order to override the default Transaction Isolation Level with a new default. .Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: Customers cannot override the default * * isolation level by creating a custom * * DataStoreHelper because the * * getIsolationLevel() method is marked * * final. * **************************************************************** * RECOMMENDATION: * **************************************************************** Five of our DataStoreHelper classes mark the getIsolationLevel method as final, and therefore customers cannot override this method using a custom DataStoreHelper. In addition, the mapping of external DataStoreHelpers to InternalDataStoreHelpers is broken such that the InternalGenericDataStoreHelper is always returned when using a custom DataStoreHelper.Problem conclusion WebSphere Distributed defects PQ79783 and 183634 already address these problems, so these changes have been merged in. The final declaration on the getIsolationLevel methods has been removed, and logic has been added to return the InternalDataStoreHelper based on meta data as opposed to the class name. APAR PQ81342 is associated with SERVICE LEVEL W502002 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
