PM72419: USING THE SOAP ADAPTER TO RETRIEVE A FILE FROM A WEB SERVICE GENERATES A JAVA OUTOFMEMORY ERROR

APAR status

• Closed as program error.

Error description

• Using the SOAP adapter with the -RAW option to retrieve a large
  file from a web service requires a very large amount of memory
  to decode the large SOAP response message. A JAVA OutOfMemory
  error can be observed if the Java Maximum Heap size is not set
  large enough allow the required memory that is needed.
  

Local fix

• WTXCQ - WTX00041385
  TR / TR
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender SOAP adapter users that use
  the "-RAW" option when decoding SOAP responses.
  
  Problem Description:
  Gigabytes of JVM memory required to process megabytes of SOAP
  response data.
  
  Platforms Affected:
  All
  

Problem conclusion

• The SOAP Adapter significantly streamlines processing of WSDL
  responses when the RAW command line option is used.  Before this
  fix, a lot of Java heap resources and processing time was
  required.  In testing, a decode of a 92 MB file took 2 seconds
  to process versus 4.5 minutes, and the JVM memory footprint was
  reduced from 1 GB to 300 MB.
