APAR status

• Closed as program error.

Error description

• Approver: ft
  
  Environment: All
  
  Problem Description:
  tacmd viewNode command could crash when large number of node are
  queried and a soap request fails. The problem is in the
  management of a failed request when the same request is splitted
  in multiple shorter requests.
  
  Recreation
  The specifc case, the customer had a managed system with the
  node name
  
  Primary: <=== Trailing ampersand
  
  The PMR ECUREP has a set of QA1* files which can be used to
  recreate issue.
  

Local fix

• Determine the unusual node and delete the rows from TNODESAV and
  TNODELST. Recyle the hub TEMS and the issue will not be seen.
  

Problem summary

• When issuing tacmd viewnode -l <myFavoriteMSL> and one of the
  Managed System Names in the Managed System List contains invalid
  characters '<', '>' and/or '/' , e.g. "Primary: <=== Trailing
  ampersand", the resultant SOAP query that is composed will be
  syntactically incorrect, the SOAP query will fail and in turn
  the  tacmd process crashes.
  
  With KBB_RAS1 setting of 'ERROR (UNIT:kui ALL)' the following
  sequence of trace messages will appear in kuiras1_*.log trace
  log ->
  
  <faultcode>SOAP-ENV:Client</faultcode>
  <faultstring>XML parse error</faultstring>
  <detail>1:196: not well-formed (invalid token)
  </detail>
  
  The above message sequence is indicative of a SOAP query that is
  syntactically incorrect.
  

Problem conclusion

• Corrections to 'tacmd viewnode' were made to filter out any
  Managed System Names that contain the invalid characters,
  preventing the tacmd process from crashing.
