IT26519: REST API PERFORMANCE ISSUES WITH POST / GET / DELETE USER ACCOUNT

APAR status

• Closed as program error.

Error description

• IBM Sterling B2B Integrator VERSION 5.2.6.3_3 and 5.2.6.2_5
  SFG and REST API:
  
  DESCRIPTION:
  
  1- The more user account exist on the system the more operation
  like READ & DELETE user account takes time :
  Around 1 seconds with 1000 user ,  2 seconds with 2000 users ,
  up to  10 seconds with 10000 users on the system .
  
  
  2- If we try to read or delete a user that doesn't exist on the
  system the REST API takes twice the time of the same operation
  if the user exist. Can take up to 25 seconds if the number of
  user on the system is around 10000 and we try to READ or DELETE
  a none existing user .
  We should get a faster return from the API when the User
  doesn't exist .
  
  3- When Creating user the user are created within less than a
  seconds , except sometimes creation can take up to 20 seconds
  regardless the number of user already in the system .
  
  increase xmx for jvm option of the liberty server and remove
  the OPS_NODE_INFO table information related to liberty node.
  That didn't bring any improvement in any areas .
