SAP Logon Groups

[Former Member]

We are trying to build up a new infrastructure with the mySAP ERP Release. We successfully did a migration from sun/Oracle to Windows2003 as Application Servers and z/OS/DB2 V8 as Database Server. Unfortunately the login from SAP GUI doesen'work. I get this error message:

Error Serice sapmsSSW not found.

We checked a lot of things like the rdisp/mshost and rdisp/msserv, but it still doesn't work.

We have 2 applications Servers.

Thanks for your help

Hi,

did you check if the sapmsSSW service is defined in the ..\drivers\etc\services file for your Windows OS?

[Former Member · Accepted solution]

Yes it is defined

Did you check that on application server or the PC using the GUI ?

after putting an enter it works. Thanks for your help

[Former Member]

the entry was in the services file. The enter was missing after: sapmsSSW 3601/tcp

[Former Member]

not not on my pc, but on the message server. I think we tried that on another pc, but it didn't work. I'll try again.

Hi Serge,

Are you sure you have an entry for sapmsSSW in your services file on your pc

It should read:

sapmsSSW 3601/tcp

[Former Member]

I made a telnet on port 3601 (System ID is 1). It just brings the message connecting to <hostname>

I just wanted to react to teh last remark of Srinivas.

You are correct that some entries are automatically created in the services file. These are the sapdp(00-99) entries. The sapms<SID> entries however are not, as the SAPGui does not know what the <SAPSID> name is.

Serge, could you also please telnet to port sapmsSSW on the pc where the error occurs and post any errors?

Best regards,

yes you are correct. I just wanted to convey that, if we create a SAPGUI icon for access through the logon group on the server, an entry will be created in the service file.

But I guess I confused everyone.

telnet works on port 3201

[Former Member]

ok,

1. Check for this service sapmsSSW on the application hosting OS, verify the port number. let us say your message server is running on port 02 , you should have a value of

a line sapmsSSW 3602 in our services file.

you can check the message server configuration in SMMS transaction

This will be automatically created if you install a SAPGUI, and access the logon group on the application server, if not add this info manually.

I notice that you will get this error only when you are using a logon group, check your logon groups, may be create SAPGUI icons once again.

It appears to me that the message server is not accessable from the computer where the SAP Gui is being executed.

Try a telnet from the SAP gui host to the central instance host on the dialog service port, which is most normally 32<xx> where xx is the instnace number.

it could be possible that some of the ports required for SAP access may be blocked in your network.

or to be more precise

with the gui installed on the application server it works, but not with the gui on the pc.

[Former Member]

It works on the application Server, but not on the PC. I must say that the server is in a subdomain, so it can only be adressed sername.test
