PQ68146: NOLOCALCOPIES=TRUE CAUSES ENTITY BEAN REFERENCES TO GET MIXED UP | |||||||||||||||||||||||||||||||||||||||
![]() |
|||||||||||||||||||||||||||||||||||||||
![]() APAR status Closed as program error. Error description noLocalCopies=true causes entity bean references to get mixed up in long-lasting transacations. The problem appears sporadically on our WebSphere 3.5.3 Advanced Server installation on AIX 4.3.3 with DB2 7.2. The symptom is that some entity bean references that are created by doing findByPrimaryKey early in the transaction at some point suddenly point to some other object (of the same type). This results in data corruption.Local fix test fix given, tried in test environment, and works.Problem summary **************************************************************** * USERS AFFECTED: All WebSphere Application Server users who * * set the System Property "NoLocalCopies" to * * "true". * **************************************************************** * PROBLEM DESCRIPTION: Users who set the System Property * * "NoLocalCopies" to "true" may * * experience a data integrity problem. * **************************************************************** * RECOMMENDATION: * **************************************************************** Users who set the system property "NoLocalCopies" to "true" could experience data integrity problems if they created a single PrimaryKey object and re-used this object for several EJBs.Problem conclusion The Container code has been modified to detect when a user has set "NoLocalCopies" to "true" in order to make a local copy of just the PrimaryKey Object to avoid any data integrity problem.Temporary fix Changed code to force a local copy of the primary key object to be created even when noLocalCopies=true.Comments
