In OIM (oracle identity manager) , our task is to " Create users in Oracle and assigning multiple roles to the users ".
(For creating users we are using BAPI_USER_CREATE1 and assigning roles to the users we are using BAPI_USER_ACTGROUPS_ASSIGN ) ,
Note : SAP system Configured with LOG ON group .
When we try to create , 100 users and a assigning roles to that , only 4 users was not created out of 100 , and the error as follows :
com.sap.conn.jco.JCoException: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed
is their any way we can fix this error
So we disabled LOGON group connection in RFC , after that all 100 users got created successfully.
Now when we are trying to create 500 users at one instance, again we are getting the above error .
So what could be the reason for this issue. Kindly suggest some ideas to resolve .
