JR53698: Modify locking mechanism for StoreConfigurationRegistry

APAR status

• Closed as program error.

Error description

• When values are fetched from the
  StoreConfigurationRegistry.getValue() method, a synchronized
  lock is obtained. Once the lock is obtained, the EJB cache from
  the current transaction is flushed. If there are any issues or
  timeouts with this flush operation, the synchronized lock may
  block other threads in parallel from similarly trying to obtain
  values from the StoreConfigurationRegistry.
  

Local fix

Problem summary

• USERS AFFECTED:
  WebSphere Commerce users on v7.0 leveraging the
  StoreConfigurationRegistry
  
  PROBLEM ABSTRACT:
  Modify locking mechanism for StoreConfigurationRegistry
  
  BUSINESS IMPACT:
  May expose other underlying locking issues
  
  RECOMMENDATION:
  

Problem conclusion

• The synchronization within the
  StoreConfigurationRegistry.getValue() is redesigned to improve
  parallel access and maintain data consistency among threads. It
  reduces the use of synchronized locks and ensures that the
  threads are not blocked for too long waiting for a lock.
