How to work with two different backend with same MI Server and war file

Question

Hi All,
We have a requirement that we need to work with one Middleware for two backends. For that we had to copy MAM30 sync bo's to zsync BO'S with the name ZMAM30. Now both sync BO'S will point to different backends.
I have a standard war file which was working well with standards sync bo's. Now to work on zsync bo's what all the changes do I have to do in the standard war file(code).
As per my knowledge we have a file called "syncbonamelist.properties" which maps the sync bo keys. Also there is another file called "mapping.xml" file which maps the package name with BO name.
Can any body please tell me, are there any other files needed to be change like "meRepMeta.xml", other than any existing code like java objects are also needed to be changed.
Your help in this regard is highly appreciable.
Regards

Hi Murthy,
I try to get my head around the question:WHY?
The reason for my question is, that this influences the answer!
Because of several reasons it is NOT possible to handle MAM and zMAM Bos at the SAME TIME on the SAME MACHINE in the way you describe it - and it makes no sence to do so at all! But anyway......
Lets say you have two backends, cause you have two different areas of the company. But both want to use the same MI server - but the client should be independend.
So you need two apps. One uses the MAM BOs and the second one uses the zMAMBos.
If this is the case, dev should be straight forward I think and you solution should work already......... so I ask myself, what is the problem you have? Do you get an error?
- First create a new MEREPMETA-XML with just the zMAMBOs instead of the MAM BOs.
- Change the two files you mentioned above.
This should be all then.
If you have a look into the implementation for MAM001Impl for example, there you find a line like:
     private static final String SYNC_BO_NAME
          = ResourceBundle.getBundle("com.sap.mbs.mam.bo.impl.syncbonamelist").getString("MAM30_040");
This takes the name from the properties file and maps it to the real BO. So changing the name in the property file to
MAM30_040 = zMAM30_040
will result in MAM uses the zMAM BOs.
Be aware: after you place the WAR file in the WEBAPPS folder and do a restart to deploy the file, you need to do a data reset to make sure the new MEREPMETA.XML is read.
AND: two apps! one for MAM and one for zMAM BOs. One APP is not possible! Cause if you have something like that in the properties file:
MAM30_040 = MAM30_040
MAM30_040 = zMAM30_040
if will only take the first reading.
But I think this is clear to you anyway
