APAR status

Error description

• PROBLEM DESCRIPTION
  Maximo for Oil and Gas memory leak in psdi.plusc.app.plusctmplt
  .virtual.PlusCFldMeterStartDate.initValue()
  
  REPRODUCTION STEPS
  Customer unable to identify the steps that triggers this code.
  However studying the code shows that mbosets are being opened
  but are not then being closed.
  Failing to close the mboset means that the mboset will be open
  until the JVM is restarted
  
  The customer's DBA has repeatedly highlighted DB connections
  that have been left open for hours at a time.
  Those concerns led to a full check of Industry solution code
  that referenced MXServer/mboset leaks - that identified this
  class as a suspect.
  
  RESULTS
  The mboset should be given closed after it has been used.
  
  UNEXPECTED BEHAVIOUR
  Database connection remains open causing the memory leak.
  
  
  Code sample
  psdi.plusc.app.plusctmplt.virtual.PlusCFldMeterStartDate.initVa
  lue()
  
  /* 68 */     } else if (mbo.isBasedOn("PLUSCPREGENASSET")) {
  /* 69 */       MboRemote defaultAssetData = mbo.getOwner();
  /* 70 */       MboRemote template = defaultAssetData.getOwner();
  
  /* 71 */       MboSetRemote mboSet =
  template.getMboSet("meterrecords", "PLUSCTPMETER", "templateid =
  :templateid");
  /* 72 */       if (mboSet == null || mboSet.count() == 0) {
  /* 73 */         mboValue.setFlag(7L, true);
  /*    */       } else {
  /* 75 */         mboValue.setFlag(128L, true);
  /*    */       }
  
  /*    */     }
