MDM 71 - mdm console and clix - unable to connect to database server

Question

Hi,
environment, MDM 7.1, AIX 6, Oracle 10.2.0.4 (installed as part of a standalone java AS)
i've an issue. I have installed MDM 71 via sapinst, before that I installed a standalone java application server. During the installation, i gave the 'oracle client', 'oracle home' and 'oracle sqlplus utility' to be those of the oracle database installed for the java AS.
After sapinst completed I tested my connection to the database via
tnsping <SID> = OK
sqlplus system/passwd@<SID> = OK
When i start up the mdm console (7.1.02.90) i can mount the MDM server, BUT when I try to configure the database settings i get
error  'unable to connect to database server'
I get the same error when i use clix dblist
Error: 0x84020004, Unable to connect with Database Server
Has anybody got any ideas.

To see why the MDM is not able to connect to database, do the following:
% cd /usr/sap/<SID>/MDSxx/log
% ls -ltr
You will find last updated log file with name like MDS_LogXXUX101224X164953.csv
% tail -100 MDS_LogXXUX101224X164953.csv
You will see the reason for not being able to connect. If the reason is:
",MDSAdminServerXGetAvailableReps,Oracle_DBConnection.cpp,205,,,,server_user,server_global,,,

OCI Attach, try again ...
Then edit the /oracle/SID/112_64/network/admin/tnsnames.ora with entry like following:
SID.WORLD =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS =
        (COMMUNITY = SAP.WORLD)
        (PROTOCOL = TCP)
        (HOST = hostname)
        (PORT = PORT_NO)
    (CONNECT_DATA =
      (SID = SID)
      (GLOBAL_NAME = SID.WORLD)
then issue:
tnsping SID
If result is like
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (COMMUNITY = SAP.WORLD) (PROTOCOL = TCP) (HOST = hostname) (PORT = PORT_NO))) (CONNECT_DATA = (SID = SID) (GLOBAL_NAME = SID.WORLD)))
