LI76427: CMVC 214356 - PREVENT UNBOUNDED INCREASE IN SIZE OF TRANSACTIONCACHEDMAP OBJECTS.

7.0.0-WS-WCServer-FP009

APAR status

• Closed as program error.

Error description

• The CalculationCodeListDataBean caches intermediate results for
  the duration of the current database transaction.  CatalogEntry
  and CatalogGroup relationships where a CatalogEntry or
  CatalogGroup has many CatalogGroup parents can cause the cache
  to grow too large.  When multiple threads execute this code
  concurrently, an out of memory condition can occur.
  

Local fix

• Avoid defining CatalogEntry CatalogGroup relationships where a
  catalog entry has a large number (for example 500) of parent
  catalog groups or CatalogGroup CatalogGroup relationships where
  a catalog group has a large number (for example 500) of parent
  catalog groups.
  
  Reduce the number of WebContainer threads that can execute
  concurrently in the JVM.
  
  Increase the JVM maximum heap size.
  

Problem summary

• USERS AFFECTED:
  WebSphere Commerce users of Version 7.0 or Version 6.0 Fixpack 8
  or higher.
  
  PROBLEM ABSTRACT:
  Large CalculationCodeListDataBean transaction cache can cause
  out of memory condition.
  
  BUSINESS IMPACT:
  Large transactions can cause OutOfMemory
  
  RECOMMENDATION:
  

Problem conclusion

• This fix reduces and limits the memory footprint of transaction
  cached intermediate results to avoid a possible out of memory
  condition.
