Logon Group JCO Connection

[Former Member]

Hi all,

I've a similar post to it, but none have solved my problem.

I've installed the ABAP 7.0 and i've a NetWeaver 2004S SP9.

I've created a Technical System to my ABAP server, when i test my JCo Connection i'm getting the following message :

-

---

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=toddy GROUP=PUBLIC R3NAME=NSP MSSERV=sapmsNSP PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR Group PUBLIC not found TIME Tue Nov 27 08:00:51 2007 RELEASE 700 COMPONENT LG VERSION 5 RC -6 MODULE lgxx.c LINE 4288 DETAIL LgIGroupX COUNTER 3

Its says that group PUBLIC doesn't exists, but if i call the SMLG Transaction, i've get

Logon Group Instance Status

PUBLIC toddy_NSP_00 green

SPACE toddy_NSP_00 green

At Change Assignment :

Assignment-dependent

PUBLIC

toddy_NSP_00

IP address : 127.0.0.1 (I'm local)

Group Dependent

PUBLIC

Ext. RFC-enabled (Checked)

Instance-dependent

toddy_NSP_00

Response Time 60 ms

User 1

If i click on Test i'm getting the following error :

Internal error (SIMULATION:INACTIVE_SERVER)

Could it be the cause of my JCO don't found the LOGON GROUP?

To Application Data i can use the option to Single Server, but it isn't possible to Dicitionary Meta Data.

I've saw ate this forum about the transaction RZ70, it has some information that can be useful to identify the problem?

best regards

Hi all,

The key point to solve the problem was the rdisp/autoabaptime

I've found a reference to it at :

After set this value to 300, the problem was solved.

Thanks.

Hi,

have you checked the entries in the SLD?

The RZ70 transaction supports you with an automatic regestration in your SLD, but maybe something went wrong and you dont have the Logon Groups in your SLD.

check it under: http://Server:port/sld

Goto -> Technical Landscape -> WEB AS ABAP -> Select the System and click on the Message Server. Check the values in Logon Groups and if you don't find your group, type it in the textbox. (For each Logon group start a new line.)

Hope this helps.

values in Logon Groups and if you don't find your

group, type it in the textbox. (For each Logon group

start a new line.)

The groups are at Message Server.

I think that the problem is with some configuration at ABAP, but i don't know how to check it.

Try SPACE instead of PUBLIC

Hi Aviad,

The same problem appears.

Check if the file C:\WINDOWS\system32\drivers\etc\services contains the entry -

sapmsNSP <port>/tcp

where port is usually 33XX, 36XX, 39XX

XX = Sys num

Hi Aviad,

I've verified and this entry is on the services file.
