Error description

• ************************  APAR Template
  *************************
  *===============================================================
  ========
  Environment:
  
    5724C04MS Tivoli Enterprise Management Server   6.30 FP6
  
  Severity: 3
  
  Problem Description: HUB TEMS may output 'false' occurrences
  of the RAS1 message of the following format ==>
  ~ ~ ~ ~
  ***ERROR: for RRN <3931>, (oldest) Index TS <garbage_data   >
  does not
  match TSITSTSH TS <1160704132623084>
  ~ ~ ~ ~
  
  These 'false' messages are benign.  In spite of the 'false'
  error
  messages, the intended functional behavior of the code is
  performing
  correctly.
  
  
  Detailed Recreation Procedure:
  This is a regression introduced by APAR IV67076.
  
  The 'false' messages are caused by a simple variable
  initialization
  error in a memset() statement.  There is zero risk to correcting
  this memset() statement.  If the TEMS builds successfully on all
  supported platforms, there will be no risk exposure.
  
  This APAR needs to be included in 6.30 FP7 to eliminate PMR
  penetration/volume.  L2 reports at least 5 or 6 PMRs, based on
  this error messages, have been handled by L2 in recent months.
  
  It is ironic that an new RAS1 message was added as a 'just in
  case' for
  a condition that should never occur, yet an incorrect variable
  initialization is actually causing the 'false' occurences of the
  RAS1
  message.
  
  Work-around: None
  
  Approver: BEH
    Initials of L3 engineer that approved APAR creation
  

Local fix

• None [Ignore the message]
  

Problem summary

• IBM Tivoli Monitoring hub enterprise monitoring server may
  output 'false' RAS1 messages about TSITSTSH table
  
  
  These 'false' messages are benign.  In spite of the 'false'
  error messages, the intended functional behavior of the code is
  performing correctly.  However,when these 'false' messages
  do occur there are large numbers of the message appearing in
  TEMS RAS1 log files.
  
  Here is example of message at issue ==>
  ~ ~ ~
   ***ERROR: for RRN <1883>, (oldest) Index TS <           !m?? >
  does not match TSITSTSH TS <1160704131915110>
  ~ ~ ~
  

Problem conclusion

• Corrected code that caused 'false' messages to be logged in RAS1
   logs.
