Cannot start java - "Connect to message server host failed

[Former Member]

Dear SAP gurus,

I performed a system copy of a SAP ERP 6.0 system but I cannot start java on my new system. I found out that the system is trying to access to the old MSHOST, R3NAME and MSSERV. I guess these parameters are changed on the configtool but I couldnt find them anywhere. Can you guys suggest me how to find them?

std_server0.out log:

Hi Venkata,

ABAP works fine.

I checked those issues and no one is the one we are currently having.

Hi,

Did you checked in configtool if it contains the correct hostname and ports as it is refreshed from source, there is a chance of existing source details.

Hi Venkata,

Yes, I checked "com.sap.security.core.ume.service" properties but all entries related are with the right SID and host name.

Hi,

I asked to check for message server port and hostname details.

login to config tool

1. Select Message Server & Bootstrap.  

1. In the Message Server settings pane you can view and edit:
2. Message server host
3. Message server port
4. Enter the new value and choose File ® Apply.

Hi Marc,

Just to add up .. You can click on the Instance ID **** where on the right side you can find Message server and Bootstrap settings as mentioned by Venkat.

Thanks,

Thanks guys I managed to correct the issue by changes those parameters on configtool. After that, I had to upgrade the kernel so the java stack is now up and running.

Hi Marc,

Can you go UME key store administration in Config tool -> Services and check the entries starting with R3master..

There you can find all the values.

Thanks,

Jagadish.

Hih Jagadish,

Can you be more specific?

I checked the properties on com.sap.security.core.ume.service in cofigtool but everything looks fine.

Any other idea?

thanks, Marc
