PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Process Server 6.0.1.3 users who
use business rules.

PROBLEM DESCRIPTION:
When using business rules in a
volume, WPS performance degrades
seriously.

RECOMMENDATION:
None

WebSphere Process Server v6.0.1.3 incorrectly included a
restriction that prevented a large number of business rules
from executing efficiently. This restriction caused the rules
stored in the repository to be read more often than necessary
rather than from reading from within the server memory.

PROBLEM CONCLUSION:                                             
Code fix is made to improved performance for large number of    
business rules
