We had a cluster, 4 physical servers / 14 SAP Instances / HP-UX - Oracle 10G / 46C -> Upgrading to ECC 6 EHP 3.
Basically we have a general RFC problem in the system. You can reproduce it simply in transaction sm51: In most of the instances whenever you try to change to an instance that has the same instance number than the one you are logged on at this moment, you will come back to this instance, e.g.:
you are logged on at host1_SID_01, start sm51 and try to change to the instances:
(or you try to display the system log or other). You will see (System - Status) that you don't change to these instances but will stay on host1_SID_01.
We found the SAP Note 662895 - Remote login using SM51 Fails. In this note they refer to the error: "Transaction termination 14 025".
We look at the SM21 it reports the following error: *Transaction termination 00 152 ( ) *
I would appreciate some tips about this problem.
