Connect Non SAP Oracle DB and MSSQL DB to SAP BW 7.0 Orace 10g system

Question

Hi All,
Well I have a scenario, where I have to connect Non SAP Oracle 9i DB and MSSQL DB (2000, 2005) to SAP BW 7.0 Orace 10g system.
There are all together 4 Non SAP systems to be connected.
Up till now I have understood that in order to have to integrate Oracle 9i to BW system - TSNNames.ora has to be updated, then create new Logical system, then Create Source system in RSA1 with all the required information, Create user at Oracle 9i end.
As far as MSSQL Server is concerned - Client Software + DB Shared  Library has to be installed in BW server.
Could anybody please guide me in the complete Basis Activities including above to complete the process.
I tried to create Source System, the initial screen has fields - Logical System, Source System & Type and Release.
I have created the Logical system through Tcode SALE
How to create Type and Release - for DB Oracle 9i & MSSQL 2000/2005.
Does OS version of DB & BW also matters ? Do we need to have that information as well.
Thanks & Regards

Hi,
I am getting following error when I try to do TNSping
C:\Documents and Settings\bitadm>tnsping HRPRN815
TNS Ping Utility for 64-bit Windows: Version 10.2.0.2.0 - Production on 06-AUG-2

Used parameter files:
E:\usr\sap\BIT\SYS\profile\oracle\sqlnet.ora
TNS-03505: Failed to resolve name
This is my TNSnames.ora file content
BIT.WORLD=
  (DESCRIPTION =
    (ADDRESS_LIST =
        (ADDRESS =
          (COMMUNITY = SAP.WORLD)
          (PROTOCOL = TCP)
          (HOST = poinmssapdev)
          (PORT = 1527)
    (CONNECT_DATA =
       (SID = BIT)
       (GLOBAL_NAME = BIT.WORLD)
HRPRN815.VSHODC.LNTINFOTECH.COM =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.25.8.79)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = HRPRN815)
Do we need to manually update Listener.ora as well so as to function.
All this is not letting me create Source system.
Gives me following errors
TNS-12514 TNS:listener could not resolve SERVICE_NAME given in connect
descriptor
Cause: The SERVICE_NAME in the CONNECT_DATA was not found in the
listener's tables.
Action: Check to make sure that the SERVICE_NAME specified is correct.
TNS-12541 TNS:no listener
Cause: The connection request could not be completed because the listener is
not running.
Action: Ensure that the supplied destination address matches one of the
addresses used by the listener. Compare the TNSNAMES.ORA entry with the
appropriate LISTENER.ORA file (or TNSNAV.ORA if the connection is to go by
way of an Interchange). Start the listener on the remote machine.
Thanks & Regards
