Configuartion of logon group !DIAG for use by web dispatcher

We are load balancing our HTTP traffic across a range of ABAP+Java Addin instances and have found that the load is balanced according to the logon group !DIAG. Does anyone know if is possible to configure this group (ie to remove the CI) or how to use a different logon group.
I think you can do something with URL mapping in SICF, but do not know how to configure it.
Regards
Jack Inniss.

Hi Jack
The internal server group !DIAG is made up of all application servers defined in SMLG, I believe. The web dispatcher uses the ICF service /sap/public/icf_info to determine the content of this group in conjunction with URL mapping.
If you exeute this service you'll see the list of servers and logon groups that will be used for the !DIAG group. Is the CI defined in SMLG ? Also, you may find the following page on SAP Help useful.

Logon groups configuration for JAVA instances using NWA method

Hello guys,
we have a BI dual System landscape (CI ABAP+ JAVA plus 2 dialog instance ABAP+JAVA, based on NW04s. I have set up a Web Dispatcher to do a load balancing for JAVA instances. I configured the logon groups according this documentation using NWA (http://help.sap.com/saphelp_nw04/helpdata/en/45/3dbe11a82b6bf1e10000000a1553f6/content.htm).
The following point is still quite unclear for me:
I have defined the instance IDs (of DIs installed on linux servers) and exacte Alias in the logon groups definitions in NWA. Is it possible to proof somehow (while accessing my URL http://<host>:<port>/TestApp~test/<application_resource> ) either in web dispatcher ->Web Administration Interface(Application Server Monitor ?) or somewhere else on which Dialog Instance I actually land to be sure that my load balancing works properly and i don't land on my Central Instance?
Thanks a lot in advance.
best regards,
Polina

ok, I have understood what you ment in the first passage Thanks!
When I put javascript:document.cookie in my Internet Explorer Address Bar i got the following information:
PortalAlias=portal; saplb_STD_JAVA=(sapt20p_T20_20)207175450; JSESSIONID=(sapt20p_T20_20)ID1892984750DB11747115157906231437End; saplb_test=(lx003207_T20_20)206509050; saplb_*=(lx003207_T20_20)206509050
what does here saplb_STD_JAVA mean?
you can use following URLs to access any particular Java Server node of any server.
https://<host name>:<https port>/irj/portal;saplb_*=<Java serer node number> https://<host name>:<https port>/irj/portal;sapj2ee_irj=<Java server node number>
What is the difference between saplb_* and sapj2ee_irj?
Thanks in advance.

Group activation for use

Typically how long does it take for the group to be activated for use after it has been approved? My group has been approved i.e members have been approved, but I still don't see my group name or any workspace name in either admin tool or workspaces? Do I need to wait?

We had an issue with the apex API due to a special character used by a user.
When did you create this group and what is the group name?
Thanks,

How to resize logo in AI file for use on web page? [was: new with this program]

Hola , i got my logo and the online company sent it in low resolution, I asked for the proper resolution for my web page and the company sent me this :
The AI (Vector) file(s) in the zip file are to be utilized for all high-res.
and commercial printing applications. It is an Adobe Illustrator file and
can only be opened and/or utilized if you have this professional design
software. All commercial printers will have access to utilize these files.
I got the adobe illustrator and I am trying to fix the logo and just can not get the size , any tip will be apprecite !

the company is giving you the vector (master) file that you can make use for web (RGB) or print (CMYK)..
logo for web, there are 2 points in here:
the size
1st. check the artwork's unit → (menu) File → Document Setup → Units → Pixels (as for web)
then resize / scale the artwork to your size needed - you can also use Width & Height value in Transform palette
the resolution (you asked for)
Ai is not like photoshop that you need to change the dpi, because the artwork is vector format ('resolution free')..
only while exporting (saving to raster) there will be dpi selection:
(menu) File → Export → Save as type (PNG / JPG) → Save → PNG or JPG Options → Resolution

Import from DVD for use on Web

Hi
aplogoies if this is "an idiot question" but this is my first foray into premiere.
A clinet for whom I'm doing a web site has given me a DVD with demos of his products in the vob format. Ie the dvd has two folders on it one audio one video I think!.
I downloaded avs video convertor and converted the vob files to AVI and mp4
If I import the mp4 into premiere they are imported ok, if I import the avi I get the following error
unsupported format oor file.
I have trawled the forum and opened the file in Gsot with the following results
I suppose I have two questions, the end video will be going on a youtube channel so am I better to just use the mp4 conversion or should I convert to AVI. If the latter why do I get this error
thanks
Ian

Hi
thanks for the fast and accurate response. Haven't tried exporting yet as I have to add a branding jpeg at the start and end of each of the 24 films.
Horses for courses created the jpeg in illustrator in minutes.
Hey ho back to the learning curve

I need to download firefox free and take it to home and download it in my laptop for using it web site developing

I tried to download FirFox free from public internet cafe and to take it to home to download it in my laptop for the use of developing htm and css codes. But unfortunatley I failed to download it. I got the answer from the "run" "this doc is corupted." So I need a help what I have to do to download it correctley?

If you are having problems downloading it from http://www.mozilla.com try downloading it from http://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.6.8/win32/en-US/
You just need to download the setup file from that page - '''Firefox Setup 3.6.8.exe'''
If you are using Internet Explorer to download the file, you can right-click on the '''Firefox Setup 3.6.8.exe''' link and choose "Save Target As"
That link is for the English-US version of Firefox 3.6.8, if you need another language, select the Parent Directory link and then choose the folder for your language.
You should also check that the internet cafe allows downloading of executable files. It is also possible that the internet cafe has security software that is corrupting the download.

How to add a barcode font for use in Web Intelligence (WebI) XIR2 and 3x?

Anyone have the steps to add a barcode font to WebI XIR2 and 3x? Not finding a good KBase on it and was also wondering if there any "gotchas" in terms of printing and exporting to .pdf.
Thanks.

Hi Kevin,
Also, if the solution provided in the previous post doesn't helps you then try the following solution.
Following are the steps to apply barcode font (IDAutomationHC39M):
1) In Windows Explorer, browse to the following folder:
-- C:\Windows\Fonts
2) On the File menu click Install New Font then browse to the font you want to install.
3) Edit the properties on the fonts you have just added:
In the "Embedding" tab, you should get a property like "Preview & Print embedding allowed".
But, nothing related to a license limitation regarding the embedding, else, you will not be allowed to use the added fonts in PDF or XLS generation.
4) Once the above points have been done:
-- Copy the .ttf fonts you want to use in the following XIR2 folder:
<BO_INSTALL_DIR>\Business Objects\j2sdk1.4.2_08\jre\lib\fonts
5) Add the following entries into the fontalias.xml file, which is in the following folder:
<BO_INSTALL_DIR>\Business Objects\BusinessObjects Enterprise 11.5\win32_x86\fonts
The template looks like the following one:

<FONTFAMILY PLATFORM="ttf" NAME="IDAutomationHC39M (IDAutomationHC39M)">
<FONTATTRIBUTE BOLD="false" ITALIC="false" LOGICAL="IDAutomationHC39M" PHYSICAL="IDAutomationHC39M.ttf"/>
</FONTFAMILY>
<FONTFAMILY PLATFORM="win" NAME="IDAutomationHC39M"/>
<FONTFAMILY PLATFORM="java" NAME="IDAutomationHC39M"/>
<FONTFAMILY PLATFORM="html" NAME="IDAutomationHC39M"/>

6) Add the following entries into the u2018i18n.xmlu2019 file, which is in the following folder:
<BO_INSTALL_DIR>\Business Objects\BusinessObjects Enterprise 11.5\win32_x86\scripts
You have different sections in this i81n.xml file.
-- Under the first section
<I18N>
<FontFinder>

u2026u2026u2026u2026u2026u2026u2026u2026u2026..
</ FontFinder>
< FontFinder2>

u2026u2026u2026u2026u2026u2026u2026u2026u2026..
</ FontFinder2>
-- Under the u2018font_aliasingu2019 section
<font_aliasing>
<T1>
u2026u2026u2026u2026.
</T1>
<TTF>
u2026..

<os type=u201Dallu201D>
<Attributs style=u201D0u201D filename=u201DIDAutomationHC39M.ttfu201D encoding=u201Du201D aliaspsname =u201CIDAutomationHC39Mu201D/>
u2026
</os>
</TTF>
7) Save the both files.
8) Restart the Businessobjects servers or local computer.
9) Login in to infoview and create a new web intelligence report by using the Java Report Panel or Html Report Panel;
10) In the left pane, select the "Cell Format Properties": you will notice that an entry "IDAutomationHC39M" has been added into the font dropdown list.
Just test the above u2018IDAutomationHC39Mu2019 barcode font, at your end and update me with the results.

Sarbhjeet Kaur

Autotyping not preserving XML element names for use in Web service

I am trying to generate a web service from an existing WSDL (ServiceOrderingContract.wsdl,
attached). The WSDL contains as a message part with an element dsl_FirmOrderProvideRequest.
Autotyping produces a corresponding class DSLFirmOrderProvideRequest. I use the
output of autotyping to implement a web service corresponding to this WSDL. I
then deploy this web service. The WSDL of the DEPLOYED webservice now has a message
part with an element DSLFirmOrderProvideRequest, per the autotype, but in mismatch
with the source WSDL. Of course, the clientgen from the source WSDL wont work
against the latter deployed WSDL.
Something is changing dsl_ to DSL in the autotyping process. Is this a bug? Or
am I doing something wrong? Is there any option in autotype task to preserve element
names?
Thanks a lot.

Hello,
Take a look at the docs on roundtripping generated data types [1]

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?

Create Logon Group on EP for Load Balancing

Dear All,
How to create logon group on EP.
This group will include group of dialogue instance systems.
(di01, di02, di03)
Current landscape is
all these 3 di are under CI(production system).
EP d/b is connected and mapped over this production system.
Now I want whenever user access EP they should not login to PRD sys but thy shd login to any one of the DI SYS.
Responce Awaited.
Regards,
Purav

please believe me, the portal has no such mechanism itself for this kind of load balancing - it is ALWAYS done by an external solution such as web dispatcher.
In a portal cluster the CI may or may not have the SCS installed (it depends on the specific installation) but each node has its own inbuilt load balancing via the dispatcher - however this is purely round robin not based on any kind of exta intelligence.
Although portal can be installed in a cluster, any nodes (app or otherwise) can be treated as individual servers. In order to balance load across any / all servers in this configuration an external mechanism must be employed.
Chances are anyone claiming to have done load balancing this way without hardware is almost certainly using the web dispatcher as an additional layer.

J2EE logon groups in an ABAP+JAVA system

Hi,
We are trying to restrict java calls to specific App servers in our ABAP+JAVA system. So if we have 5 App servers, we want all J2EE requests to go to 3 Apps only.
We are using SAP web dispatcher for this purpose. When checking on SAP help site, it suggested two options.
1) Configuring Logon Groups on AS Java
2) Configuring Logon Groups Using Configuration Files
Which of the above would be a better option for ABAP+JAVA system?
Has anyone implemented this before? If yes, can you share your experiences/lessons learned??
Thanks.
Fahad

1. Log on to the ABAP system.
2. Call transaction SPRO.
3. Go to SAP Solution Manager Implementation Guide -->
SAP Solution Manager --> Basic Settings --> SAP Solution Manager
System --> General Settings --> Client Copy
4. Perform the following steps:
a) Maintain Profile Parameters
b) Create Client
c) Copy Client 000
d) Convert UME

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,
Thorsten

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

Clarifications regarding logon groups

Hi All,
I need some info regarding logon groups. I know we can create and maintain logon groups using txn SMLG.
I'd like to know exactly what logon groups are?
For what purposes do we need them? i was told that logon groups are normally used when debugging applns (so as not to hinder performance). Can anybody throw more light on this? Thanks!
cheers
Prachi

Prachi,
the Logon group is most useful when you have clustered system architecture for your R/3 server. Suppose in a production environment you have 2 or 4 physical servers maintained for you single R/3 system - this is a very common scenario. Now when a user comes to logon - his logon should be redirected to the server node with least amount of load at that point of time. Where the load calculation is done by the message server - this logon group helps routing the user request to the actual server with least load. If you dont use Logon group you are basically asking to logon into a predefined server node among these 2 or 4 nodes. But when you use Logon groups you are basically taking the benifit of the system to decide where your logon should take place actually. Following is a line from SAP Help:
Log on to a group. In this case, the application server with the best response time is selected automatically
Hope it helps!!!
