IO03645: INEFFICIENCIES IN C++ API'S USERMGMT->UPDATE(USERGROUP). ADDINGUSER TO A LARGE GROUP TAKES A LONG TIME.

APAR status

• Closed as program error.

Error description

• Adding a user to a large group takes very long.  There is an
  inefficiency in C++ API's usermgmt->update(usergroup).
  

Local fix

• N/A
  

Problem summary

• When adding a user to a large user group using C++ APIs,
  performance is very slow.
  If a user group has about 1000 users, it may take 45
  minutes to add a user to the user group.
  

Problem conclusion

• Two new APIs are added to the DKUserMgmtICM class.  They are:
           1. DKUserMgmtICM::update(dkUserGroupDef* pUserGroup,
  dkCollection* pUserColl,
               short sAction), where action can be either
  DKUserMgmtICM::DK_ICM_ACTION_ADD
               or DKUserMgmtICM::DK_ICM_ACTION_DELETE.
           2. DKUserMgmtICM::update(dkUserGroupDef* pUserGroup,
  dkCollection* pUserColl,
               short sAction, short sOption), where sAction is as
  described before, and sOption is
               DK_CM_DO_NOT_ROLLBACK_ON_ERROR. when used in the
  delete action.
  
  When using either one of these new APIs, the add or delete a
  user to or from a large user group will only take several
  seconds instead of 45 minutes.
  

Temporary fix
