IJ24641: MAXIMO DOES NOT LOG A 503 ERROR STATUS CODE

APAR status

• Closed as program error.

Error description

• ERROR DESCRIPTION:
  Maximo does not appear to log a 503 error
  status code
  
  PROBLEM DESCRIPTION:
  While troubleshooting session
  growth / stranding in maxsession we have identified what
  appears to be a defect in the way 503 status codes are returned
  by Maximo's webcontainer. Maximo does not appear to send a
  status code of 503 when a capacity related error occurs
  (instead sending a standard page with the error and a status
  200). I believe it should send the error with a status code 503
  to allow for the IHS plugin to either mark the server down or
  send the request to another JVM.
  
  For example:
  
  When uisessions
  climb >=2 and:
  
  mxe.webclient.maxuisessions=2
  mxe.webclient.maxu
  isessionsend503=1
  
  Maximo returns an error page showing text of
  "The maximum number of users are logged in. Try again later
  after some users have logged off.".
  
  The status of this page is
  200, not 503. This means the JVM cannot be marked down or
  redirect requests to an alternate JVM
  
  PERFORMANCE ISSUE:
  
  No
  
  
  ENVIRONMENT:
  App Server IBM WebSphere Application Server
