Multiple clients with role production

Dear SAP experts,
Is it possible to assign the client role "production"  (in scc4) to multiple clients in 1 instance. If the answer is yes then how can it be done because if I try to do it via ssc4 i get an error that there already is a production client..
I have searched the forum, SAPNET  and googled but I could not find a definitive answer.
Thanks for your patience and answers.
Regards
Dirk Visser

Hi all,
I discovered that it can be done. Just set the role to production and ignore the warning.

  • Is it possbile to have multiple clients on our Production instance

    We have our Production system with client 101
    Our abapers want me to create another client 500 (config only - not easy to accomplish)  to be used for our Mexican users.
    I told them to create another company code for Mexico, but they do not know how to do this.
    DO I have any other options, of yes
    Pros and cons of having multiple clients in same production instance.
    I know that any independent code is going to effect all clients.
    THanks
    Joe

    Hi Jo,
    you CAN create a new client, but mostly this is not done, because the effort to maintain multiple clients is mostly higher than just different company codes. Yes, ABAPs are client indpendent and therefore valid for all clients.
    So, the argument, to "not know" how to create different company codes is not valid to me !

  • How to handle multiple clients with DatagramSocket

    I am trying to handle multiple clients with 1 datagramSocket bind to one port (basically I have only one port to use, and I can not use TCP or any other ports). At the server side I have two threads one for receiving packets and buffering them, another for processing the packets in the buffer and sending replies.
    I can have multiple clients sending datagramPackets to me and I will have to process the packets and send them to DIFFERENT clients. Ex. Client 1 sends datagramPacket to Server which sends the processed packet to Client 2. Also Client 2 sends a datagramPacket to Server which again processes the packet and sends it to Client1. May have Client 3 and 4 doing the same thing at the same time... and so on...
    My root class is creating the datagramSocket(somePort) and two threads (receiver and sender). How can I use the socket that I created in these two threads??
    I have done the following and I am getting "java.net.bindexception". When I am sending stuff from Client1 to Client2 everything is fine but when I start sending something from Client2 to Client 1, I get the bindexception... Client 1 is using port 3000, Client 2 is using port 4000.
    I really don't have a lot of experience in socket programming so I am not sure if there is a much simpler way to do this. I appreciate all the tips and help that I can get...
    Thanks...

              udpSocket.send(op);
             catch (IOException e)
              e.printStackTrace();
    }Also for development and testing purposes, I am running the two clients and the server on the same machine (windows xp-32b) so all of the Destination IP Addresses are 127.0.0.1. and as I said Ports that I am using are 2000, 3000, 4000 (Server, Client1, Client2).

    Hmm I have minimized the code and it seems to be working now.
    I think I have an error in the header portion of the data I am sending, where I am storing the source IP/Port and destination IP/Port. I think the server in the middle is messing these values up while sending them to the destination Client. Because the destination client actually receives the stuff and sends the reply back to the server, but the reply packet's headers has 0/0 as the dest IP / Port...
    Server is giving me java.net.BindException: Cannot assign requested address error when it tries to forward the reply it received from the client2 as the address it is trying to send is 0!
    I guess it doesnt just give this error when you try to open two sockets to the same port...
    Paul, Thanks for the direction on how to proceed... took me a while get the minimized code but at least figured out the problem. Well still have to make sure that is THE problem though :)
    As far as the statics goes how can I change those to non static ones? Where do I make an instance of the top level class that creates the threads? and how do I pass the DatagramSocket to the threads/ if I dont need to pass how do I call or use the datagramSocket I created in the top level class? I mean do I still kinda have it like a global variable on the top?? A very simple example would be much appreciated...
    I think these might be really basic questions but I am having a rough time with the hierarchy in java...

  • Multiple clients with same account on a single IMAP server

    Hi,
    I am connecting to a IMAP server using same account but from 2 different machines. From one machine a mark a message as SEEN=FALSE. But on the second machine, the flag will still be TRUE.
    Is there any way to co-ordinate between multiple clients so that all the clients are in sync.
    Regards,
    Nitin.

    I was able to resolve the problem using addMessageCountListener and messagesAdded method, as suggested by you.
    I am now facing another problem. Whenever a new message is received, code inside messagesAdded method gets executed. Here I am trying to spawn another thread and do some stuff. But this new thread is not starting at all. It goes into some JavaMail:EventQueue and does nothing. What is the concept of EventQueue here? How can I get this new thread executed?
    Also will there be synchronization problems in messagesAdded method. Say I received a message and I am processing it in the messagesAdded method. In the mean time another message comes up. How will this behave.

  • Need best practice to deploy similar content to multiple clients with specific skins/images

    Hello, my name is Bernadette. When I was with a previous employer for several years I created WebHelp using RoboHelp 8. Then, the last two years I worked there I transitioned to MadCap Flare again creating WebHelp. I have been with a new employer two years now, using RoboHelp again. However, this company still has us creating HTML Help only. My manager has just assigned me to create and launch our first WebHelp project. Currently, we have RoboHelp 8, with a P.O. in process to purchase version 9 hopefully very soon. However, I cannot wait and have just started the project using version 8.  Since it's been a few years, I am a tad rusty in my use of RoboHelp/WebHelp. For this first project, I have been asked to customize the skin for EACH client that transitions to the new proprietary application. My question is, since it is likely that the contents of the completed WebHelp project will be identical (with the exception of the customized customer-specific skins, logos and window images) is there a creative, timesaving method for rolling out primarily the same content to each customer WITHOUT the need for me to maintain numerous, individual WebHelp projects?  I so appreciate any input or suggestions. Thank you!

    Hello Peter and Jeff, there IS the potential for eventually reaching a HUGE number of customers, but I would expect that to take at least a good number of months or beyond to get to that stage. As for Peter's question about variables, I have used conditional build tags in the past, which I know is a variable, but I am not certain what else might be included in the category.
    I was not aware that it is possible, within a single project, to create and maintain different versions of the same layout type, namely WebHelp by creating  duplicates for each customer. This could be challenging, but fun! So, as I get further into this I assume you are both "on call" for additional questions? Thank you both so much for your rapid responses.  

  • Solman CHARM: adding multiple clients for quality/Production systems in Solar_project_admin

    Dear Colleagues
    We are using Solution manager 7.3. When we setup system landscape under a solution manager implementation project, we can only select one development and one quality/testing system.
    Our scenario is that,
    Development System:
    D40 - 010 : (both workbench and customizing changes being done in same client)
    Quality System:
    Q40 - 010 : for customizing changes
    Q40 - 000 : for work bench imports
    So the querry is that, how we can add these two separate rows in Solar_project_admin and under tab systems:

  • Multiple clients in CRM Dev/QA system

    Hi All-
    I've seen in various places that it is recommended to only have one client in a CRM system. I have worked at many sites that have several CRM clients in a system without issues.
    Can any one point me to an SAP Note or document that recommends only one client per CRM system? I realize that there are possible issues with the CRM pricing and cross-client customizing downloads but these can usually be worked around. What other issues are a concern?
    Any SAP document about this would be great.
    Thanks!
    Tim

    Tim,
    Unless you are going to have multiple back ends or some business scenario that requires multiple clients in CRM Production, then don't do it in CRM Dev/QA.
    The reason why don't do multiple clients in a CRM system that is connected to an ERP backend is the following:
    CRM configuration is dependent on downloaded configuration from the ERP system.
    A normal CRM system should only have one backend connection.
    Now why would you want want to have a Dev and QA system that does not reflect how your production system works.  In fact in the case of CRM you are making more work and creating systems that do not accurately mirror production.
    The whole gold client concept in CRM is honestly a bad idea when you have single ERP backend, because it just causes more work for people and it my opinion its a way of people trying to stay busy than add real value.
    Now if you really want to keep busy maintaining middleware and keeping things in sync, go for multiple clients in Dev/QA.  The best part is when something in Prod breaks you won't have any environment that mirrors Prod correctly from a middleware perspective.   In my opinion if you are that concerned about configuration and master data mixing then you probably need a CRM sandbox instance to try things out.
    Take care,
    Stephen

    First i installed portal with rapid installer 2.5.1 but it connects only with client 000. i tried to give client 100 at installation time but it was not accepted.
    Then i installed with netweaver 04 dvd. it accepted client 100.
    now my company want that portal should be connected to multiple client with backend system as my backend system is development and they will check first in a sandbox client and then with user testing in a test client.
    How to do this.
    Secondly, in user management>role "page cannot be displayed" error and this error is coming only in this page.
    One thing i should tell you that when i installed with rapid installer it was working fine with client 000 but when i changed the client in system landscape i was able to logon no tab displayed. the message was that the user may not have proper authorizations. may be something to do with portal roles. I want to know how can i transport these portal roles or user config to other clients.
    in WP3R, it says no object found.

  • 2 Clients with Production Role in Production server , possible ?

    My company has implemented 2 Systems SAP Landscape with one development and one production server. So far , we have one client in Production server been configured with Production role and one more is configured with customizing role.
    If possible to configure the client with customizing role in production server to production role ? I tried but the syatem always tell me that a client with production role is already exist.
    Kindly advise .
    Thanks.
    Leon

    Hi, Rohit :
    Once again . Thanks for your input .But , I really can't try what you are suggesting here as my production system is running 24 hours per day and I can't really take the risk by just trying open and close the existing client with production role .  Based on your 1st reply , you said that Production system is possible to have 2 clients with production role . If it is so , there should be settings that I could configure to achieve this rather than trying  to reconfigure the existing client with production role.
    Thanks.

  • What are the possible approches for hosting a product(custom SP application) for multiple clients on a single SharePoint farm?

    We have a product which is a custom application based on SharePoint Foundation 2010. Right now, for each of our client we create a dedicated server and host the application in the standalone deployment. Now, the requirement is to host multiple clients in a
    farm deployment.
    Challenges are: 1. The product has same name for the wsp that is deployed on different client servers as of now. How to distinguish for different clients on same farm
    Currently the product specific css and jquery is in 14 hive. These files will be of difefrent versions for different client. How to segregate that?
    How many web applications is recommend to be created in a single SPF 2010 farm? What are the challenges?
    There are a couple of DBs created in SQL for the application. What is the best way to separate those for the client?
    Essentially its the same product but with different versions for each client that we want to deploy in a single farm. What is the best practice to tackle this?

    For the most part, these are not SharePoint questions per se, but product-specific questions you'd better ask the vendor about. To get in some more detail:
    1. It totally depends on the scope of the solution. If its global, then you're out of luck and any changes you make affect all instances that use it. Better ask the vendor about it.
    2. Not that many, let's say < 10, assuming you're web applications have separate application pools. Check out  http://technet.microsoft.com/en-us/library/cc262787(v=office.14).aspx#WebApplication for
    more info.
    3. This is very application specific and really should be answered by the vendor. Not related to SharePoint at all.
    4. Again, really depends on the product so better ask the vendor.
    Good luck!

  • NLS_LANG setting for a client with multiple Oracle servers

    Hello!
    We have a web application which has to connect to one of the Oracle servers with different charactersets. When the NLS_LANG on the client is a single byte encoding and the server has a single byte encoding there are no problems. We have now a server with NLS_CHARACTERSET UTF8 and all special (hungarian accented) character are replaced.
    When we set the client to UTF8 the rest of servers does not work.
    What is the solution for one client and multiple servers with different encoding?
    Is there a special key in connection string?
    I tried to change the nls_lang with an alter session statement but without success.
    Regards,
    emeriqus

    NLS_LANG is not depending on the database side, it's a CLIENT setting to "let Oracle know what encoding is used on the CLIENT" so that Oracle can do the conversion from the client encoding to the database (NLS_CHARACTERSET) encoding.
    for ONE application/client the is only ONE correct NLS_LANG value, regardless of the database NLS_CHARACTERSET
    If you web application is really an UTF8 application (check with your vendor) then you can perfectly use a UTF8 client setting and a 8 bit database
    Of course, you will be limited to the database side in this case seen the 8 bit characterset does not know all the characters in UTF8
    The fact that setting the NLS_LANG to UTF8 "does not work" with your web application is simply the fact your application is not a UTF8 env.
    Setting nls_lang to UTF8 will not "magically" make your application UTF8, NLS_LANG is depending on the encoding used in the web server.
    But the first thing to ask yourself is if CURRENT data is correctly in the Oracle database.
    use SQLdeveloper to check the data, this is a "know good client" that needs no NLS configuration.
    You can download it from http://www.oracle.com/technology/products/database/sql_developer/
    If the data is displayed correctly in SQLdeveloper then you are sure it's correct in the database.
    If data is WRONG in the database then that needs to be corrected first, "trying" different client side configurations will only make matter worse (even if they make the data "look good" )

  • 640 SID With BW Layer - Multiple Clients?

    My company installed SRM (SRM_SERVER 500 SP #7) with the BW layer (BW 350 SP # 14) does it make sense to have a multiple client strategy in the non-productive SRM SIDs?  Does anyone have any SAP white papers on client strategy on the new dimension products (BW, CRM, SCM/APO, EP, etc.)?  Since I am not a BW developer I am uncertain as to why in BW it only makes sense to have 1 client which I would guess if a new dimension SID has the BW layer active then it would make sense to only have 1 client as well?  Any information would be most appreciated.

    Hi Ken,
    SAP NetWeaver BI cannot use multiple client because the objects it creates and uses are client independent. In fact only SAP NetWeaver AS ABAP (usage type AS ABAP) based system offer the potential of a multi- client solution. AS JAVA based applications do hot have a client concept, they tend to have multiple instances (i.e. one per client).
    I'm having a little difficulty understanding one part of your question ".. would guess if a new dimension SID has the BW layer active then it would make sense to only have 1 client as well?...". Can you elaborate on the question?
    Are you asking, if the SAP NetWeaver capability one has one client, does it make sense to have only one client in the ABAP based application too?
    Cheers,
    Mike.

  • How to control one server with multiple clients via TCP/IP

    I am wanting to control a single server with multiple clients.  Only one client would be active at a time, so there would be no conflict.  I want to use TCP/IP.  So far, I have programmed a cluster that passes data back to the server with no problems.  The challenge come in when a second client is added to the mix.  I have't been able to figure out how to turn each client on and send the appropriate data and then turn it off so it doesn't keep sending the same data to the server. 
    Here are the things that I have considered and did some preliminary testing, but don't really know how to impliment:
    1.  Send a numeric on the front of the cluster packet that tells the server that data is on the way.
    2.  Send a boolean on the front of the cluster packet to somehow turn the server TCP/IP on.
    The problem I have found is that LabVIEW TCP/IP doesn't like to be turned on and off.  If it doesn't get the data it expects, it goes into a reset mode and that kills the response time.
    Any help?

    You should consider implementing a set of simple one-byte commands that can be sent back and forth between the Server and the Clients. You can base all of these ideas off the example in the Example Finder under Networking >> TCP and UDP called Multiple Connections - Server.
    You will have two loops in the server VI: one to wait for new connections, and one to send and receive data from the existing connections. For instance, after one of the clients connects, it can request control of the server to send data to it by sending the character "R" for request. Every time the send/receive loop of the Server executes, the first thing it can do is to check all the existing connections to see if any of the clients have sent a control request ("R"). If so, it will create a buffer (array) of control requests. This could be in the form of Connection IDs or indexes in the array for a particular Connection ID. Your choice.
    After the Server receives a request for contol, if it is not already under control by another client, then it can send a response to the first client on the control request list. For instance, the server could send the first client a "S" command for send. Note that after the clients send their control request, they should execute a TCP Read and wait indefinitely for the server to respond with the one-byte "S" command. Then, once the client in control is finished sending data to the server, it could send the character "X" telling the Server to release it from control.
    The example I mentioned above already does a similar thing. Note how when a client wants to disconnect, they send the letter "Q". You can see this in the Multiple Connections - Client VI. The Server then checks each individual connection to see if it's received this one-byte command, and if it has, it closes the connection to the client. This is what you would want to implement, but instead of having just one command, you'll have to distinguish between a few and build up a buffer of control requests.
    Finally, if a client does decide to disconnect in your application, they could send the command "Q" just like the example above. At this point, close the connection and remove that Connection ID from the array of connections. You will also have to handle the case that this client was in the request control waiting line when it disconnected, in which case you need to delete it from that array as well.
    This will definitely work for you, but it will take some work. Best of luck!
