APAR status
Closed as program error.
Error description
WebSphere Enterprise Service Bus ( WESB ) 7.0.0.3 customers may experience reduced performance or thread locking when unknown or schema-invalid elements, attributes or types are encountered when validating an XML instance document. This is because the XML Schema gets repeatedly loaded for each message and this load step is synchronized.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All IBM WebSphere Application Server Feature* * Pack for XML users * **************************************************************** * PROBLEM DESCRIPTION: Customers may experience reduced * * performance when invalid data is * * encountered. * **************************************************************** * RECOMMENDATION: * **************************************************************** A thread locking of the schema registry is needed when an invalid or unexpected component is encountered. If the document contains multiple instances of this invalid data then the performance will drop significantly.
Problem conclusion
The invalid or unexpected components are stored to avoid locking the schema registry after the first instance of this component is seen. The fix for this APAR is currently targeted for inclusion in fix pack 1.0.0.9.
