Create a logon group as Message server

Hi,
please explain me with steps for how to create a logon group as Message server usage for few jco destination is must.

Hello Kishore ,
To create or assign Logon group for Jco connection use Tcode SMLG :
Create a group name e.g PUBLIC and assign the instance profile of central instance and Dialog instance.
You can create Logon group or assign existing logon group into Jco destination.

Logon groups not visible/usable

Hi,
I'm experiencing problems with using logon groups for load-balancing connections to my NSP 7.01.
Ultimately I want to create a JCo Connection from my CE 7.1.1 to the ABAP system and CE forces me to use a load-balancing connection using a message server and a logon group. But in order to test the proper configuration of my ABAP system, I'm simplifying the scenario but just attempting to log on to the system via Sapgui with load balancing.
Here's my setup:
It's a local scenario where both Sapgui and the AS ABAP reside on the same server.
The system has SID NSP and SysNr 02.
The proper services (sapmsNSP 3602/tcp plus sapdp02, sapgw02) and hosts entries are present on the server.
Everything else works fine
The instance knows itself as tron7661_NSP_02 (I had to correct some errors in the standard installation
Profile file NSP_DVEBMGS02_TRON7661 contains: rdisp/enqname = tron7661_NSP_02, rdisp/myname = tron7661_NSP_02
In transaction SMLG, I created a logon group HUGO, assigning instance tron7661_NSP_02 with attribute "Ext. RFC enabled" = true and everything else left blank.
When I press the "Test" button, I get message "Internal error (SIMULATION:INACTIVE_SERVER)" (Message no. RZ783). I can confirm and save anyway. A green LED is displayed in the "Status" column for my logon group.
After restarting the server, I would expect the new logon group to be usable when creating a new entry in Saplogon.
In Saplogon, I choose "Create new entry", connection type "Group/Server Selection", and enter the host name of my message server TRON7661.
As a result, a single entry "tron7661 (tron7661_NSP_02, DIA UPD ENQ BTC SPO ICM)" appears in the field "Group/Server".
This entry represents not a logon group, but a single application server.
(When I try this for other SAP systems and message servers in my landscape, I always get the logon groups configured for this systems plus an entry for the application server.)
Do you have any idea what might be wrong here?
Thank you and best regards,
Thorsten
P.S.: I have found and reviewed thread /message/208613#208613 [original link is broken] but found nothing helpful in it.

Hi Raja,
Thank you very much! -- Thomas' blog solved my problem. It was in fact just a matter of running the report that makes the configured logon group usable.
Best regards,

Logon Groups in ABAP system

Hello All,
I have set up SLD on my J2EE Web AS to connect to my newly installed ABAP 2004s system. After the set up in RZ70, I am able to see my ABAP system listed in the "Technical Systems-> WebAS ABAP" in my J2EE engine's SLD.
Now, I am trying to set up JCO connections in webdynpro content admin. And I can't see a logon group in the wizard.
Do I need to create a logon group in my ABAP 2004s system? If yes, how do I create one? Do I need to add any users in the logon group? I am a novice about logon groups, is it similar to a member group in portal? What other settings do I need to give to this newly created group (if one needs to be created).
Thanks,
Ky

Thanks Michael. I created a logon group ("MYLGNGRP") and published to SLD using RZ70. Now I can see the logon group in my SLD in the message server settings.
However, when I create a JCO destination and "Test" it, I got the below error.
[code]com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=XXXX GROUP=MYLGNGRP R3NAME=NSP MSSERV=sapmsNSP PCS=1 ERROR Group MYLGNGRP not found TIME Mon Mar 19 18:17:58 2007 RELEASE 640 COMPONENT LG VERSION 5 RC -6 MODULE lgxx.c LINE 3515 DETAIL LgIGroup COUNTER 1 [/code]
Is there any configuration that needs to be done on MYLGNGRP?
Thank you,

About logon groups

Hi all,
We are using SAP GUI 710, Here no option(groups) to create logon group for user individually, so how can i create logon group for users? please help me in this regards,
thanks,
praveen

Assuming you have already created the logon groups in SMLG...
Add sapms<SID> 36xx/tcp to your local services file.
ex..my system is BP0 00 so...sapmsBP0 3600/tcp
Then go to Saplogon 7.10 > New Item > User Specified Systems...
In Connection Type drop down - select Group/Server Selection
Enter fields...
Description - Verbage to be presented on the Saplogon Gui screen
System ID - <your SID>
Message Server - hostname, full hostname or IP of the SAP Server
SAPRouter - skip it for now
Group/Server - press the drop down menu and it should find your logon group(s)
If not add a SAPRouter string....my format is..
/M/<hostname, full or IP>/S/<port# - normally 3600>/<logon group name>
then try the drop down menu from the Group/Server field again...
Good Luck...

URL logon groups are empty in SMMS

hello,
i'm trying to configure http load balancing with message server.
i've created a logon group and assigned it to url webgui in SICF
it seems to work but in sape note 751873 it is said that logon groups and corresponding urls could be loaded and checked in transaction SMMS using functions via Goto -> Expert functions -> HTTP
the problem is that, here in SMMS, my url logon groups list is always empty...
is it normal?
regards

Hi Olivier,
In case you use Integrated ITS in a Portal environment you should have a closer look at notes 1029194 and 1040325.

Logon group PUBLIC ?

I've installed the latest NW2004s SP11 and created a logon group PUBLIC in MSLG but I can't logon with that group.
Even when I try to create a proxy in VS2003 and .netNCO, the wizard tells me that there is no PUBLIC logon group on my msg server.
Is it possible, that this feature is disabled on the trial products ?
Best regards, Harald.

Specific logon Group for Http logins

Hi
I just wondering whether we can have Logon group in SMLG specifically for http logins to use only 3 app server out of 6.
In my case,we have given one of the app server in the Iviews so all http logins goes to it, But as I see this server is idle most of the times and my other app servers are overloading and hanging sometimes so to allow GUI users on this and distribute http logins to use only 3 servers.
And If I use the generic load balancing then all the request would come to Central instance and then go to app server,which I don't want because I restricted any users login to central instance .so What I am looking is, to distribute Http logins to 3 app servers only .
Can this be acheived???
Any ideas are welcome.
Thanks

Hello,
you can create a logon group in SMLG with those 3 application servers, then set the flag ""Ext. RFC-enabled" in SMLG.
If you use the Message server for Http load balancing you should activate the services sap/public/icf_info/logon_groups and sap/public/icf_info/urlprefix in SICF transaction.
You could as well assign specific logon groups to url's in transaction SICF.
There are some restrictions when using the message server for Http load balancing (depending of your scenario), see SAP Note 1040325. That's the reason is recommended to use SAP Webdispatcher

Installing Messaging Server on Windows XP

Folks, I'm trying very hard to install the Messaging Server on my laptop running XP. Actually, I'm interested in evaluating the Calendar Server, but it seems I need the SJSMS as well if I want to be able to programmatically subscribe to notification events when items change on the SJSCS.
Unfortunately, I can't really tell if the darned thing installs as part of the JES installation. It doesn't show up in the program group under Sun whereas Calendar Server, Portal Server, etc. all show up.
So I tried re-installing just the Messaging Server. It promptly removed everything else from the Start->All Programs->Sun program group. The other bits and pieces still have their directories all available, but interestingly, the log now shows that calendar server isn't running any more. Still no Messaging server in the Sun program group.
So I tried re-installing yet another time. This time is claimed to UNINSTALL the SJSMS!
I'm at the point where I plan to uninstall the entire JES and start again. This is an evaluation install, so I'm just hoping to have the Calendar Server and the Messaging Server (and of course, the Directory Server as it's a required component for the other two).
My question: Does the SJSMS work on XP? If so, what's a good way to test? I can't seem to find the JBiff.java program anywhere on my system, although the docs indicate that's what I should use for testing! I also can't find it online at Sun's web site.
Thanks,
MK

Java Enterprise System 2005 Q4 supports Windows XP as developer evaluation platform. Messaging, Calendar are part of this release. Both can be evaluated on Windows XP starting from 2005 Q1 release.
From the original message, the main issue seem to be missing Messaging in Program groups. Messaging Server is not directly
installer under C:\Sun similar to other products, it is installed C:\Sun\server-root as it requries the Administration Server.
There should be services created for Messaging
Please see the summary.txt file in your install root that describes where Messaging has been installed and other details thaat are used for setting up the evaluation configuration.
To evaluate calendar, select custom option, choose 'configure automatically; in product selection, uncheck all products, select Calendar (which auto selects other dependencies),and proceed.

Two questions about Logon Group

About logon group, it describes as below in the help.sap.com.
1. Each SAP application has different resource requirements. Certain applications may therefore require more servers and logon groups. For example, you should assign separate servers for the application component PP.
Q1: How a certain application use more than one servers via logon group, and how it use sap memory which resides in different servers?
2. If it is not practical for you to assign separate servers to integrated applications, such as the application components SD-MM and FI-CO, you should assign common logon groups to these applications.
Q2: I don't understand this sentence exactly.
Thanks so much.
James

Not sure if I exactly understood what your problem is, but let me give it a try:
A1: One logon group may have several servers attached to it. If users user1, user2, user3, ... are going to connect to the logon group, they will be sent to different servers. None of those users will be able to use memory from more than one server. But, let's say user1 and user2 will use resources from server1, whereas user3 will use resources from server2. The goal is that all servers will have the same (or similar) load, just by distributing users.
A2: If it is not possible to have four logon groups for the four applications SD, MM, FI, CO, but you still want different logon groups, then, at least, you should create two logon groups, one for SD and MM, the other one for FI and CO. That's because resource requirements are similar for SD and MM, and for FI and CO.
hope this helps

Messaging Server 3.6x NscpMail process continues to grow until memory used up

After upgrading to Messaging Server version 3.6, I have found that the
NscpMail process
continues to grow until I run out of memory and the system eventually crashes.

One solution to this problem is to remove the problematic messages. 

<OL>
<LI>Shut down the Messaging Server (see details
below).

<LI>Move all of the message directories to a temporary location
(see details below).

<LI>Create these directories again for Messaging Server (see details below).

<LI>Re-start the Messaging Server (see details below)

<LI>Examine the message files in the old queue (from Step 1) for
corrupt headers.

<LI>After you have checked the messages, manually forward the message bodies
to the intended recipients (see details below).
</OL>

<HR>

How messages are stored: 

Prior to delivery, mail messages are separated into three files:
control, body
, and header
. 

The body and
header files are stored in
the following directory: 

server root/messages

The control files are
stored in the following directories: 

server root/control 
server root/deferred/Error-Handler 
server root/deferred/Account-Handler 
server root/deferred/SMTP-Router 

Removing messages from the queue and
re-introducing them later:</A> 

<UL>
<LI>Shut down the server using ./NscpMail stop
 

%cd /etc 
%./NscpMail stop 

<LI>Move the directories to a temporary location.</A> 

%cd server root/postoffice
%mv control control.sav 
%mv messages message.sav 
%mv deferred deferred.sav 
%mv hold hold.sav 

<LI>Create these directories again for the Messaging Server.
</A> 

%mkdir control messages deferred hold 
%chown mail-user control messages deferred
hold 
%chgrp mail-group control messages deferred hold
 

<LI>Start the Messaging Server using ./NscpMail
start.</A> 

%cd /etc 
%./NscpMail start 

<LI>Forward the message bodies:</A> 

After you have checked all of the messages for corrupt headers, you can copy
the messages back into the queue, at most 1000 at a time. 

<UL>
<LI>Use the cp command
to copy files instead of the mv
command.

<LI>Copy the body and
header files into their
respective directories first. Then, copy the control
files into the control
directory. Copying the
control files back into the
control directory will
cause the corresponding messages to be processed the next time the server
flushes the queue, which is done every hour.

<LI>When you copy the control
files, make sure that you also copy
the corresponding body
and header files.
Otherwise, you will receive errors that say the body
and header
files cannot be opened.

<LI>To copy groups of body
and header
files and their corresponding
control files, you can
use the cp command with
wildcards. For instance, to copy all the messages that arrived between 12:30
and 12:40 back into the queue, you can use the following commands: 

%cd server root/postoffice/messages.sav 
%cp 199080325123* server root
/postoffice/messages 
%cd server root/postoffice/control.sav 
%cp 199080325123* server root
/postoffice/control 
%cd server root/postoffice/deferred.sav 
%cp 199080325123* server root
/postoffice/control 
%cd server root/postoffice/hold.sav 
%cp 199080325123* server root/postoffice/hold 
</UL>

Next time when this happen it will be great if you can create statspack snapshots during the problem. Then you will have more insight information of what's going on in Oracle.

Messaging server with 2048 bit key

I am in the process of renewing my SSL certificates and a change requires the use of 2048 bit keys.
Is there a way using msgcert to specify key length?
It looks like certutil will allow a different key length. If I use certutil to create the database, will the message server work with a longer key?
I am using SSL for POP/IMAP proxy and SMTP on Messaging Server 6.3.

Logon Group in a Cluster

Hi,
I have CI - 02 on one host and dialog instance -03 on another host.
I have created a logon group by name public and assigned these 2 instances.
My question is if one instance got down how the user will automatically switch over.
It's cluster environment already installed.
Let me know if u need information.
Regards,
Saravanan.S

Hi,
If I undestand correctly, you have a CI on cluster (MSCS ?) and a SA on a third host.
Your logon group includes both the CI and the SA.
It means that your users are, eithe connected on the CI or the SA.
With this architecture, you don't have High Availability.
If you user is connected on the CI and there is a cluster fail over, the user will be disconnected if the CI node failed.
If your user is conencted on the SA and there is a SA failure, the user is disconncted.
For HA, it's better to have at least 2 SA on 2 different hosts and to include only the 2 SA in the logon group.
Regards,
Olivier

How to create Logon groups for JAVA Systems

Hi,
I am implementing an BI JAVA Landscape. We do have 1 Central Instance(CI) and 2 Dialog Instances (DI) JAVA Standalone. Everything based on NW04s
I have set up a Web Dispatcher to do a load balancing. The Web Dispatcher is connected to the Message Server (MS) of the JAVA CI to get all the information about the Engines.
I am now looking to create Logon groups to distibute the load according the application used applications. I am not sure if there is a possibility to set up logon groups (server groups) directly somewhere in the J2EE engine, or if I have to set this up in the WebDispatcher konfiguration files?!
Thanks in advance and best regards,
Dominik

We're trying to do something similar with NetWeaver CE 7.1.
According to [this documentation|http://help.sap.com/saphelp_nwce10/helpdata/en/45/3dbe11a82b6bf1e10000000a1553f6/frameset.htm] there are 3 steps to doing this for NetWeaver CE 7.1:
1. Logon Groups
2. Web Dispatcher profile changes
3. HTTP Provider property changes
We've set up a Logon Group in the NetWeaver nwa and associated the two instances (one host) with it.
"[Configuring Logon Groups Using Configuration Files|http://help.sap.com/saphelp_nwce10/helpdata/en/45/3c3f0cad9f4c2de10000000a1553f6/frameset.htm]" says: "...to create the files using HTTP Provider service."
There it doesn't say exactly how to generate those 3 text files; it says: "1. Create the icrgroups.txt and urlinfo.txt files that define the logon groups. For more information, see the documentation of SAP Web Dispatcher." ; but, has no link to what it says to see. So, I manually go to ["SAP Web Dispatcher", "Assigning Logon Groups"|http://help.sap.com/saphelp_nwce10/helpdata/en/b4/9aa8862e714e6db8e74e48e5d3283b/frameset.htm]. But, it all pretty much breaks down there because it's referring to apparently non-NetWeaver CE 7.1 stuff (as near as I can tell); for instance, how do the transactions SMLG and SICF relate to NetWeaver CE 7.1, or am I in the wrong place?
I tried to press ahead with files similar to the examples here, but I hit this error in the Web Dispatcher:
[Thr 5132] *** WARNING => ICT: path prefix /Curam/ not allowed in this context. Only prefix / allowed. [ictxxptab.c 764]
[Thr 5132] *** WARNING => When a file is specified in wdisp/J2EE/url_map_location only URL prefix '/' is supported. See also SAP note 1033470. [icrxx.c 2925]
The note reference looks hopeful, but I cannot read it; I get:
Note 1033470
The requested SAP Note is either in reworking or is released internally only
Does anyone have a copy of this Note or knows if it's helpful?
Has anyone done this with NetWeaver CE 7.1?
Tahnks,
William
