JR38611: MEM LEAK IN MQCC WHEN PUTDATE.TAG/PUTTIME.TAG DATA ELEMENTS USED

APAR status

• Closed as program error.

Error description

• Abstract : Memory leak in MQCC when the PUTDATE.TAG and
  PUTTIME.TAG data elements are used.
  
  Description :Memory leak is observed in the MQ Connector read
  job when WSMQ.PUTDATE.TAG or WSMQ.PUTTIME.TAG Data Elements are
  used. The reason for this memory leak is, CC_Calendar class
  object instances are being created without a matching destroy
  instance. Since we pass on the object to the Connector
  framework, either the object needs to be deleted in the
  framework, or pass a static instance of the object to the
  connector framework. The framework leaves the onus of releasing
  the memory onto the caller. Hence, we are passing a static
  instance of the object as part of the resolution.
  

Local fix

• NONE When these Data elements are used.
  

Problem summary

• Memory leak is observed in the MQ Connector read job when
  WSMQ.PUTDATE.TAG or WSMQ.PUTTIME.TAG Data Elements are used. The
  reason for this memory leak is, CC_Calendar class object
  instances are being created without a matching destroy instance.
  Since we pass on the object to the Connector framework, either
  the object needs to be deleted in the framework, or pass a
  static instance of the object to the connector framework. The
  framework leaves the onus of releasing the memory onto the
  caller. Hence, we are passing a static instance of the object as
  part of the resolution.
  

Problem conclusion

• Properly modified the code to handle the memory leak when the
  Data Elements WSMQ.PUTDATE.TAG and WSMQ.PUTTIME.TAG are used.
  

Temporary fix

• NONE when the Data Elements WSMQ.PUTDATE.TAG and
  WSMQ.PUTTIME.TAG are used.
