Two SID installation a single machine.

[Former Member]

Hi All,

If I am installling Second SAP installation in a single machine then previous Application Server is not working. Mean SID 1 is running and I have now install SID 2. After completion of SID 2 installation SID 1 will automatically goes down and SID 2 is working fine.This is happening on both cases when privious SAP SID is running and shutdown condition.

I have chaecked both database, they are working fine.

After starting its goes STOP - Dispetcher. And It shows Application Server fails if I am connecting Previous System.

As per my accessment problem with Application Server.

Can Anyone give solution.

Regards,

Yes Finally I Got the solution.

please check

>r4trans -d To Check Conectivity between Apps and DB Server.

If 000 then its OK- mean connectivity is OK, in this case all work.

• when I was installing Second system then tnsname.ora and listner file was creating and privios system entry was removed. DUE to that reasion First one goes down.

Solution:- Both system entry should be Listner and tnsname file. Then Both server will work.
