Error description Backport the EJB finder performance enhancement that is already in distributed ver 5.1Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: When a finder is issued by a caller, * * the EJB 2.0 specification for * * Persistence Management 'Flush before * * find' behaviour is being ignored by * * the runtime. All beans, even those not * * related to the finder, are flushed. * * (backend data updated). Data may * * prematurely be placed in the backing * * store. * **************************************************************** * RECOMMENDATION: * **************************************************************** 'Flush before find' behaviour is required by EJB 2.0 Spec, which means before a finder is driven to the database, all (dirty) beans related to that finder must be flushed to the backing store to ensure that the most up to date data is available to the finder in question. A problem exists where all beans are flushed, not only the dirty beans.Problem conclusion Code has been modified to only flush those beans related to the finder which are dirty. APAR PK00472 is associated with SERVICE LEVEL W502024 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
