I’m back in basis land yet again. What I discovered is that in order to connect to multiple systems existing on the same server, they must have a unique instance number. After all these years, I finally understand what the instance number does =) Since several of my SAP systems exist in the same server name, I had to make a change. I installed everything in 00, not know any better.
Well after some internet research, I discovered how to do this (at least for the ERP systems).
1. Go to the profiles directory. For me it was: C:\usr\sap\<SID>\sys\profile\
2. There are 3 files in this directory that you need to visit. (keep in mind, depending on the parameters, you may or may not have things to update).
a.<SID>_DVEBMGS<NR>_<Server name>
b. START_DVEBMGS<NR>_<server name>
c. DEFAULT.PFL
For the 3 files, replace every instance of DVEBMGS<old NR> with DVEBMGS<new NR>, sapgw with sapgw, and SAPSYSTEM = <Old NR> with <new NR>.
3. Next rename the directory DVEBMGS<old NR> with DVEBMGS<new NR>
4. open up the command prompt cmd.exe
5. Execute the following command: C:\usr\sap\<SID>\sys\exe\uc\ntamd64\sapstartsrv.exe -r -s <system> -n <NR> -p C:\usr\sap\<SID>\SYS\profile\START_DVEBMGS<NR>_<server> -U .\SAPService<SID> -P <password> -q
6. Execute: C:\usr\sap\<SID>\sys\exe\uc\ntamd64\ntenv2reg Select the new service.
7. Now restart the server, and you should be able to start the system with the new instance number.
8. Don’t forget to update your logon pad to the new instance for the system.
Now, I tried these same steps on my 4.7 system, and I couldn’t get it to work. I’ll try it again later, and if I get it working, I’ll let you know.
Good luck,
Mike
