ChaRM config with two dev clients
Hi Experts,
Has anyone tried ChaRM with two dev clients, one for customizing and one for workbench, is it like adding two QA/prod systems?
Please help.
Thanks and Regards,
Jamuna Nithyanandam
Hi Jamuna,
Like already mentioned, maintain 2 logical components in SMSY with the correct systems, and add these logical components to your Project.
When in a Change Document (U.rgent or Normal Correction), the action 'Create Transport Request' is executed, a pop-up will be shown and people can select where they want to have the Transport created.
Of course, SolMan will always show the two options - Workbench or Customizing Transport - when creating the Transport Request. So people need to pay attention that there are only creating WRKB in the WRKB-client and CUSTO in the CUSTO-client. As far as I know, this cannot be limited technically in SolMan.
Good luck!
Best regards,
Roel

ChaRM config with Single domain
Hi Guru's,
I am in situation where I have to configure Change request Management with Single Domain Controller in Solution Manager 7.1 SP11.
I have configured transport routes in ECC development system (000) to Integration , quality and production and now I want to add this configuration to Solution manager without domain link.
please help me on this greatly appreciated
thanksHi Srini,

How faces-config with two resource bundle???
Hi all,
In my application,
I want to put several message bundle in faces-config.xml.
How can I do that?
I defined two message bundle like
<application>
<default-render-kit-id>oracle.adf.core</default-render-kit-id>
<message-bundle>com.resource1</message-bundle>
<message-bundle>com.resource2</message-bundle>
<locale-config>
<supported-locale>en</supported-locale>
</locale-config>
</application>
but the application cannot get messages in resource1 file.Hi,
you need to load the bundles on the page
<f:loadBundle basename="Bundle" var="msg"/>
<f:loadBundle basename="Bundle2" var="msg2"/>
<af:outputText value="#{msg[\'message.key\']}"/>
<af:outputText value="#{msg2[\'message.key\']}"/>
Then you can use strings in both properties files. If you only need the strings of one file, delete the other reference

How to handle multiple DEV clients in CHARM
Experts:
We have many DEV clients in our ECC landscape.
Some customizing needs to be imported into all DEV clients.
In order to use CHARM to do above import into different DEV clients, I want to define some logical components with only
2 systems, i.e. source DEV client and target DEV client (e.g. DEV100->DEV200). Then link this logical component to a
project.
In this way we will define many projects (logical componets, maintenance cycles) depending on how path combinations existing on the STMS setup.
Could you help verify whether this will work as expected? Because I did not configure 2 system tp for CHARM before therefore I am not sure.
Thanks a lot!Hi,
you should take a look to those 2 threads especially the second one IF those other clients are USED FOR CREATING TR:
Re: Multiple clients in DEV and QA for CHARM setup
Change Request Management for multiple production clients
IF the other clients should just be synchronized with custo done in the first one then the lines above will help you.
Important fact "A Solman Project can have more than a logical component."
So for example in your case if you are trying to update DEV 200 with DEV 100 when importing TR to quality system (200 must be a kind of reference client for you),
you ll simply have to declare a Solman Project containing the core logical component (for ex: DEV 100 -> QUAL 100 -> PRD 100) AND another one that ll let you import in DEV 200 (DEV 100 -> DEV 200).
In your generated tasklist you'll then find DEV 200 under Target Systems node; like if it was a QUAL system AND you ll find tasks as "Import Transport Requests" available for DEV 200.
As a prerequesite you MUST declare DEV 200 in your logical component as a Target Role System and not as a Source Role System (like DEV 100) (Transaction SMSY). Otherwise Solman will understand that DEV 200 will be used only for creating and releasing TR and it will be considered like DEV 100
Hope it helps
Keep me updated with how it goes

Does two seperate client required if the solman monitors DEV and QAS system
Hi All,
This is our client landscape:
1 Dev-SolMan->For all development and quality systems(ECC 6.0, BI and EP).
1 PRD-SolMan->For all production systems(ECC 6.0, BI and EP).
Note: We have build only DEV-SolMan system as of now and we haven't done any configuration yet like either service desk or ChaRm.
The question is:
Do we need to have two seperate clients in DEV-Solman, one for all development systems and one for all quality systems? or Can we have a single client in DEV-Solman to handle all development and quality systems? What is the SAP recommented approach?
Thanks
SanjaiHi,
you even don't need separate Solution Manager systems to monitor DEV / QA and Prod. You could use one SolMan client to monitor and administrate all systems / clients.
Maybe it would be a good idea to create different Solution Landscapes, but this depends on your need.
Separate clients are no good option, because CHARM can only activated in on client. Also if you plan to activate charm, you need a solution that contains all systems in your transport landscape (DEV, QAnad Prod).

How can i split Client Network traffic and My exchange traffic with two differnet ip address?
Hello Everyone
sorry for my bad English and also my bad explaine
here is my network looks like
all the client on one subnet and network is 192.168.0.0
i have Dsl router that connect to Tmg server
i have Tmg with two NIC
1-192.168.0.4
2- 2 Public Ip address
i want to do this
i want to split user's traffic and my exchange traffic
i mean i want to route user's traffic with one public ip addresss
and my exchange server's traffic with another public address
but when i add additional ip address at Tmg or create new NIC card
all of my traffic route with one public ip Address what should i do?Hi Uhan,
You need to use ENAT fuction on TMG to achive this
On the External NIC assing the Second IP as Additionl IP address (VIP)
Create a network Rule to NAT traffice From Exchange server IP address to the required Public IP which you need the E NAT.
Ensure you are creating rule only from Exchange server IP and not all INternal.
Look at the below Doc you step by step config
http://www.isaserver.org/articles-tutorials/configuration-general/Configuring-One-to-One-NAT-TMG-2010.html -
Connection of One BI Dev with Two R/3 system
Hi All,
I am working on the BI project and i am having below problem/daubt.
we are having three system landscape for R/3 .i.e R/3 dev,R/3 qty,R/3 Prod.
In BI we are having two system landscape BI Dev and BI production.
R/3 Dev is connected to BI dev properly and we have already developed all the reports in the BI dev. We have used all standard BI contect comopenets and then migrate them into 7.0 (transfer rule, update rule, info source, data source).All queries are customized.
We are having very less amount of data in the R/3 dev , so we are getting less data in BI which is not sufficient for analysing.
So, we have create one more connection and connect our R/3 Quality with BI dev(R/3 dev and BI dev connection is still there).
Now, i want to pull the data from R/3 quality. I think i have to again install all the standard BI contect and migrate them for R/3 quality which is really big job.
Again, We have installed all standard BI content and migrate all 3.5 to 7.0.
is there any other way by which i can use my current modeling with new sources?
Regards,
Macwan James.Hi,
The way that u said is a big task.
One suggestion with out mapping R/3 QTLY to BI DEV is.
Copy the Data from R/3 QLTY to R/3 Dev.So you will get sufficiant data for testing.
I hope this is one point that you can think and easy to implement also.

[ChaRM] 2 DEV clients and 2 QA clients
Hi
I have a situation where 2 DEV clients and 2 QA clients exist before release to production.
DEV
100 Workbench
200 Customizing
QA
100 Test 1 (for vendor)
200 Test 2 (for customer)
PRD
100 Production
Transports from DEV 100 and DEV 200 need to be released to QA 100 and 200.
(sometimes to only one of 2 QA clients, which makes it even more complicated)
If I apply SolMan ChaRM to this enviornment, what configuration are recommended?
(SMSY, TMS???)

Cannot work with two client side applications at the same time!!
Hi guys,
I developed two client side applications(applets). Locate the on Apache/Tomcat. There is also a Index.html file with two links, so when user clicks on each link the associated application will downloaded on his PC and ready to work. (In index.html I used window.open(�) to load the applications)
Now please see this scenario:
1-I ran/loaded both application in two separate browsers(IE5.5). And tried to work with them(minimized one and work with another). Soon I faced unexpected frizzing/locking or very slow running on both applications.
2-Then closed/killed one of them(killed IE). Then re-executed same application again. The application loaded with the last activated screen . Seems it never killed and it was still alive.
3- The only way to successfully working is one by one.
means execute & work with one, then kill that, and then execute and work with another.
To Debug:
When both applications were running(each on it�s own IE), I opened the Task Manager and saw there was only one IEXPLORER.EXE was running, also there was only one Java VM (a small bird icon) on right-bottom of the screen.
I believe this causes the problem. seems they both running in the same session. Since I opened two applications in two IE I was expected to see two IEXPLORER.EXE with two JVM. Am I right? Do you think so?
Any way, Now I am seeking to find the solution. My primary mind says probably I should not use window.open(..) in index.html to load the applications.
Would appreciate any command on this.Cross post

Hi,
SRM 5.0, Extended classic scenario
I have completed the config. with one SRM and one R/3 (back-end) scenario. It is functioning well !!.
Now I have to add one more R/3 into the existing SRM box.
Can you please let me know the key configs, I have to do it.
With regards,
PranavHi All,
Thanks for your reply.
Hi Atul,
>>>Basically, the important things are with the Document Types, Number ranges, >>>account assignment categories, material groups/product hierarchies, Item >>>category, etc..
I am bit nervous !!! now.
Is your above statement valid for the SRM box ?. If yes, why do I need to change this config as it works well for the (first) R/3.
or
Are you saying the (new) R/3 Document type etc should be synch with the SRM box ?
Please advise me.
With regards,

EP Implementation with two different CRM client on same EP environment
Hi All,
I have the following scenario
We want to use same EP instance for connecting to two different clients in ECC 6.0 system (say Client 100 and 200 ).
But we also want to use Single Sign On.
Then my problem is
1. When I am logging on to EP through URL it should directly Log on to master client (say Client 100) setup during the single sigh on.
2. But then if another user wants to connect to Client 200 how he will do that ?
Is connecting two different client from same system from Single EP instance is possible ?
Pls help me on that. It's very urgent.
Thanks and warm regards
PurnenduPurnendu: as I mentioned in your duplicate thread. It is certainly possible to connect two different client of the same system - but you have to have two different iView and two different system objects from them. You can have a single role and two iVIews inside that one connecting to 100 & another to 200 client respectively.

Election problem after repeated split-brains with two nodes
Hi
I'm using a customized source based on BDB-5.1.19 (excxx_repquote)
with two site one - MASTER and the other SLAVE...
nsite=2
ack=quorum
- the master is writing to quotedb at a rate of 10 txn per sec
- the test consist to isolate the client from the master (split brain) and reconnect it after a random time include from 1sec to 10sec
the test run well about 10 times but at a moment the process slave receive DB_EVENT_REP_ELECTION_FAILED
and the master enter in election mode and never exit from the CLIENT mode. I must say that to freeze the client I decide to kill me (kill -9 my pid) when I receive such event...
here is the verbose log on the master...

* These pieces of information are expressed by the following flags.
* -h home (required; h stands for home directory)
* -l host:port (required; l stands for local)
* -C or -M (optional; start up as client or master)
* -r host:port (optional; r stands for remote; any number of these may be
* specified)
* -R host:port (optional; R stands for remote peer; only one of these may
* be specified)
* -a all|quorum (optional; a stands for ack policy)
* -b (optional; b stands for bulk)
* -n nsites (optional; number of sites in replication group; defaults to 0

Problem with Oracle 9i client to access multiple oracle databases
I am having problem setting up oracle client 9i to access multiple oracle db. When I finish installing Oracle 8.x client, I simply replace the tnsnames.ora that the installation created with the ones that I have. I can access three different databases. I only need to add three diffrent entries in the tnsnames.ora file. I cannot be able to do this with Oracle 9i client. I follow the instruction from the CD installation to use local naming method. It appears that Oracle client try to create multiple entries on my tnsnames.ora file but I can only be able to access one db.
Any help is appreciated.
Thanks! HDthe old tnsnames.ora is working with Oracle 8 client. The new tnsnames.ora (if I use the Oracle Net config) have two entries, one is dev and the other is prod.
Thanks! -
Can log into Yosemite server (4.0) VPN service with a Mavericks client, but not Yosemite client
Sever Info:
Yosemite Server 4.0 running on a late 2009 Mac Mini with 8 GB RAM with vpnd service enabled
The server was upgraded to Yosemite - not clean install - this may not matter (see below)
Airport extreme router with standard VPN UDP ports for L2TP forwarded to server (500, 1701, 4500)
Client info:
MB Air 13" early 2014 with 8 GB RAM
Yosemite
Mavericks 10.9.5 running as a Parallels virtual machine (don't ask - I need it to run an app for work that is not yet compatible with Yosemite)
OD service is NOT running - no VPN connections ever occurred from ANY client with this service running - OD is not needed in my case fortunately
With the OD service off, I can connect via the Mavericks virtual machine just fine, but not with Yosemite. With Yosemite, the ppp connection appears to occur, but server config requests appear to fall on deaf ears (client side doesn't appear to respond) until the connection times out. Can't figure out what triggers the client response to a server config request. Client side complains about no route to host and IP addresses don't get assigned to the connection.
The connection happens successfully in an eyeblink with the Mavericks client. Same username/password/shared secret in both instances.
Tried a generated .vpnconfig from the server, this also did not work.
It's possible that it is an auth problem, but can't figure out how the process occurs or what may be going wrong. There does not seem to be an obvious way to increase the granularity of the logging such that it might give other hints - at least that I can find. I found plenty of references to VPN issues when people upgraded from Mountain Lion to Mavericks as well as work arounds for this. I tried the most promising looking of those - no love. I reverted everything back to stock install since I could at least connect with Mavericks.
If log entries would be helpful, they are included below. I've stared at them long enough - perhaps a new set of eyes can provide a hint.
In addition, I can find no documentation regarding the VPN service in Yosemite server so as to get a clue as to whether there have been changes in racoon since Mavericks.
Thanks in advance for any suggestions. I would be glad to supply any other info needed for an accurate diagnosis .

2014-10-21 12:10:09 MDT --> Client with address = 192.168.1.226 has hungup1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Is it a good idea to save emails in the raw format (.eml)?
We currently save all of our emails onto a server, organised into projects, as RTF files. We're thinking about saving them as raw files (i.e. .eml) as there is more fidelity and you can include attachments. However, we're worried that these might not
