Project of Jini Implementation in China.

Hi, everyone!
Let me introduce myself, first. I am now a student studying at
Beijing University of Post and Telecommunication(BUPT), Beijing,
Capital of China.
Then give a brief introduction of the project I am now participate in.
Recently our project leader arranged a task (implement an intelligent
network) to us. This network platform will said to be proposed to those
customer electronic companies in China. The main framework is OSGi.
And as for the OSI layer3~6, originally we want to use UPnP technology.
(The programming langague based has been decided to be Java.)
But quite recently, we have learned that UPnP mainly relies on IP protocol,
so if we want to connect IP net with non-IP net using UPnP, a bridge is needed.
Then we start to think about the availability of Jini. Though having gone
through with specifications of Jini, we still have some questions as follows:
(If the answers are simply in some references, just give me a link to save your time.^^)
1. Can network implemented with Jini connect IP net and non-IP net together? (How?)
If the answer is "yes", then how do components in a non-IP network implemented
with Jini communicate with each other? And what are the protocols used in
communication of this kind?
2. This question is related to the price to realize this network. Two reasons why
we are not content with UPnP is that you have to use a bridge to connect IP & non-IP
networks, and that you have to use SCP technology to control non-IP network.
Both add expense to realize the network. However, if we use Jini, is it expensive
as well? We know that in Jini network, a server is a must. Is the realization of
adding a server to the network expensive? Plus, chipset on which Java VM runs
is another cost. Is the price of adding chipsets to the clients and
the devices (which provide services to clients) very high?
3. Because we want to our project to be a success, we extremely care the future of
Jini. This care became deeper when I saw, in a Chinese developer forum, a question
("Is Jini dying?") yesterday. When I went to SUN developer forum, I found that
the Jini forum is not active (readable only). Few companies claim to add Jini to
their products. So my last question is "What do you experts forsee the future of Jini?
Does Jini still have a rosy promise?"
Thank you for wasting your time to read this post!
And thank you very much if you can express your thinking here!
Your, Josh Zhu, BUPT.

Hi Uryikin,
Thanks for your response.
Standard Retractor does not satisfy the Business requirement in full.
The RFC connection you have suggested is what we are implementing through RSPLAN function Type creation.
In the RSPLAN we are implementing a Class which will fetch the Data from the Infoobject.
This infoobject will be fed from the target Infocube. After this Class getting populated Mapping will be done b/w BI source fields and the R/3 source fields.
Now the problem arise when a Function Module needs to be created that will actually bring the data to R/3 side.
The server where  Data Load function Module is to written is still unknown to me..
The Function Module Return type is also unknown...
As this is totally customised we have to identify the return type for submission of Blueprint...
Kindly refer to this link we are implementing this same steps only on different scenario...

  • Linking solution manager projects with CHARM implementation project

    Hi Guys,
    Currently i am working in CHARM implementation project, i have created one CHARM implementation project with urgent correction and i am able to create the Transport request and release the transport request succesfully and i am able to move it to quality system successfully. But my customer is asking to link the solution manager project to CHARM implementation project.
    Earlier before implementing CHARM they have implemented project managent in solution manager, during that project they have created so many projects which are currently running, now they want those projects to be linked CHARM implementation project.
    When ever they create a transport request through CHARM they want the TP to be saved under a respective project which they are using currently. but according to my knowledge the TP can be saved under CHARM implementation project only.
    Now i want to know whether the projects created in SOLAR_PROJECT_ADMIN can be linked to CHARM implementation project. Pls give ur valuable inputs as it is very urgent.
    Thanks&Regards
    Raju

    Hello,
    We have implemented this with two systems landscape where in we have in place a Solution Manager Dev system and Solution manager Production system both are SOLMAN 4.0 with SP12. So the path for us to move the changes is from Development Systems to Production system.
    We have ChaRM between the Dev and production. We reapplied the satellite system concept. For us the Solution manager Prod is a satellite systems all the changes that we move from Development system to Production systems is tracked with necessary documentation in the ChaRM process.
    Yes, I agree with you that this is not any big magic. Working with two SOLMAN implementation, I strongly feel that SAP needs to have well rounded ChaRm processes. We have robust Change Management Process, but when we moved to ChaRM we were limited functionality of the ChaRM processes.
    I had approached and did some research on how other companies are implementing the same process. Most of them have almost the same process for tracking SOLMAN changes. I am still look out for improved process to manage SOLMA changes.
    Hope this helps!!! Thanks

  • Template project reference in Implementation Project

    Hi,
    I have defined Template Project & created Business Blueprint hierarchy for the same.
    Now I need to refer the Template Project in Implementation Project.
    1) How to refer Template Project in Implementaion Project ?
    2) Can I get the Template Project reference in Implementation Project automatically in Scope OR do I need to do some settings ? Currently I am not able to see the Template Project in Scope.
    Regards

    Hi Kumar,
    Refer below links. Should be useful and also I am assuming that you have created master template and you want to refer master in local implementation project.

  • SAP BW support Project error in implementation

    Dear Friends,
    My company got a support project in Business warehouse Intelligence, with a retail chain manufacturing and selling fashion wear across India through its chain of stores & other resellers.
    This SAP BW was implemented by a SAP partner and no documentation is available and I find following issues to be solved apart from other issue that I have solved:
    1. The datatargets are activated some in 3.5x and some in 7.0 i.e. some having infosource u2014> datasource u2014> transfer rules u2014> update rules u2014> infopackage while others are having transformation u2013> DTP u2014> Infopackage,
    my question is should I convert all datatargets in 7.0? If yes what are the benefits? And how?
    2. For every datasource there are quite a few infopackageu2019s created for loading data.
    Should I delete the unnecessary infopackages?
    3. For infocube 0FIAP_C02 the data is supplied by ODS 0FIAP_O02, the data is loaded correctly but in case 0Creditors which references 0Vendor the master data is available in the system but is not displayed in the infocube and in the query.
    How do I sort this issue?
    4. Quite a few Process Chains is created and active, but as mentioned above the data extraction is happening through a few infopackages.
    Should I deactivate the process chains and carry out data extraction manually till the system is stable and then activate the same after checking the dataflow?
    5. And lastly to create/ change/ view queries though we are having latest patch for SAP GUI 710 we are not able to carry out above activities.
    How do we solve this?
    Waiting earnestly for guidence.
    K Sengupto

    1. It's up to you to use 3.x or 7.x flow If you have enough resources/time you can Migrate them to 7.x Flow
    Ofcourse you will have advantages over 3.x like you will only transformations which replaced Transfer rules and updates rules as well and easier to manage and you will DTP  -> Error stack / Debugging / Rich delta functionality
    2. Normally we will have Auto Infopackage for Delta and also one for Manul infopackage(incase for 'Repair full') .. Check all the IP's If there any filters in each package to upload data to targets .. If you feel they are unnecessary then you delete them or keep them they doesn't impact
    3.You don't need to load 0CREDITOR if it's being referenced by 0VENDOR since MD is shared for reference objects
    4. Try to understand the unused PC's and their purpose sometimes we will have PC's for delta and also for Full loads to avoid manual interaction, and we will have pc\s for full loads as well .. If there are many pointing to the same target anyalze and delete them .. you can remove them from schedule (if they are scheduled) and later you can schedule as per your needs
    5. Check If you have enough authorizations / check SU53 - If you are missing any authorization objects and contact basis team to get access.

    Hi Aditya,
    Many Thanks. I am new to this feature ( Template project & roll out).  My requirement is like, I need to define one template project & same has to be rolled out in other contries implementation projects. This is in a broder sense.
    Now what are the steps to go about. How to proceed.
    Will there be only one Solution Manager or different countries will have sepearte Solman. Will one Solman will do all rollouts.

  • Oracle Project Analytics - Project Manager Security Implementation

    Has anyone implemented a security scenario for Project Managers, such that they can only see the information associated to their projects when using EBS as the source? If so,
    - How did you identify the relationship between project managers and their projects? Did you use an initialization block and pull this information in from EBS?
    - Where did you define the security/filtering configuration so that they were limited on what they could see?
    - Did you create a custom responsibility for 'Project Managers' and have them access a set of Project Manager dashboard/reports that followed the Project Manager security model?
    Thanks in advance.

    Please note that I have posted this same question/thread in the BI Apps forum. I didn't want to duplicate effort, but I know different users may only come to this forum. The link to the original thread is below:
    BI Apps Forum Thread
    Oracle Project Analytics - Project Manager Security Implementation

    Coolmesh84,
    Thanks for the great info and reply. This makes complete sense to me, but I just want to make sure I am clear on a couple points:
    +1. Use an initialization box to filter the user's emp id+
    You mean use an init block to pull the users employee id and store it in a session variable correct? The session variable will then be used later as part of the filter criteria.
    *2. and add a filter to the required dimension table in business layer to filter based on the project_manager_id column for the project manager group.+*
    To implement the step above, would you follow theses steps:
    1. Go to Manage->Security
    2. Under Groups, select the group planned to be utilized for this filter (in this case I double clicked the Project Manager group).
    3. I then Click permissions button for this group
    4. Go to the Filters tab of the window that pops up
    5. Add a filter, go to BMM tab and select the Project dimension and then define a filter for Proj Mgr Id = nqsession.employeeid
    +3. Ideally you should be able to use the OOTB project manager group for this security.+
    This is a good point, but a few more questions here - There are a number of Project related groups (see below) in the out of box Oracle BI Apps RPD and all of them essentially roll up to the super group 'Operating Unit Org-based Security'. Is there a best practice or preferred approach for utilizing these groups as they related to Oracle EBS v12? Is there any good documentation out there to see what the intended use and setup is for these groups? Do all of these groups relate back to an EBS Responsibility? I have read through the OBIA Security Configuration document and basically all it says is to enable the operating unit org initilization block and thats all .. not really all that helpful.
    Thanks again - k

  • Project kickoff,post implementation

    what is the project kick off?what is the post go-live?

    Hi,
    Project Kick-off is the time when the plan is finalised, approved and the project work starts.
    Post go-live usually refers to teh activities and production support involved once the project goes to Production system.

  • Not able to see General Documentation in Implementation Project

    Hi All,
    I've created one Template Project and one Implementation Project. Now I've added some documents to Template Project - General Documentation Tab. Ideally this newly added documents should be appeared in Implementation Project - General Tab. But in my case I am not able to see this newly added documents. Is there any reason behind this? What should I do to make them visible in Implementation Proj - General Documentation tab?
    Another question is, If a document from Project Documentation tab is deleted by pressing 'Delete Row' button (not actual 'Delete' button), how can I retrieve that document? How can I see the list of all deleted documents?
    Thanks in advance!
    Shaun
    Edited by: shaun99 on Feb 16, 2012 4:28 PM

    Hi Shaun,
    For the implementation project, please read the session  "USING THE TEMPLATES" in the wiki page for template projects, where it explains how to update your project with the changes made in the template project.
    -http://wiki.sdn.sap.com/wiki/x/gRkMDg
    regarding the download, I'm not aware of any easy way to do mass download of the documents. Maybe in SI80 you could do such thing but I believe you would only be able to filter by the folder where the documents are phisically stored and as you're using a template project, all the documents are stored in the folder SOLAR00, shared along with solutions and etc..
    more info about this in the wiki page for documents in solar01 and solar02:

  • Copy teammembers and keywords from template to implementation project

    Hello All,
    When adding structure elements (business scenarios, etc) from a template project to an implementation project, the data on the administration tab is not copied with it.
    When selecting a specific scenario from the template we need to be able to also copy the keywords and team members to the implementation project.
    1) Is this possible without custom development
    2) If we use custom development. How can I link a structure element to its Administration tab data (keywords and team members) in ABAP?
    Thanks
    Jurjen

    If you copy the entire project using SOLAR_PROJECT_ADMIN, and then delete out of scope scenarios using SOLAR01, then the administration data can be copied over. Note, however, that this only works for the initial project copy. Subsequent changes to the information on the Administration tab in the Repository cannot be carried over to the projects using SA_PROJECT_UPGRADE. Another restriction is that you can't copy a template project to an implementation project. Also, if you want to use further template functions such as the Global Attributes, then you have to bring scenarios in using  the template functions, where this data is not copied over.

  • Re: Roles of  ABAPER in implementation project

    HI experts,
    What s the Roles of  ABAPER in implementation project?and responsibilities in support project?

    <b>IMPLEMENTATION </b>:This is project in which we implement sap for a company from scratch right from creating tables and data for the first time..writing code for the first time etc.
    <b>SUPPORT</b> : this is the kind of project where SAP has been already implemented but due to some additional business requirement or any thing like small problems in general they hire a team who work for them to solve the small issues.its also called issue based project.
    It depends on the Volume of the company and how many company codes and Plants it have and for how many it has to be implemented
    There are different types of Projects in SAP:
    1. <u>Implementation</u>
    Customer wants to install SAP/Include different modules of SAP viz. MM/SD/FI/CO/PP etc for the first time.Previously he might be using some legacy system in his orgn. This is implementation project. Here one needs to integrate several modules, migrate data from Legacy system to SAP system. Need to prepare interfaces/RFC's to interact with 3rd party systems.
    Most of the company's follow ASAP methodology for the Implementation projects
    there are 5 stages in the ASAP methodology
    they are
    1. Project Initial Preparation
    2.Business Blueprint
    3.Realization
    4/ Final Preparation
    5.Golive And Support
    ABAP work mostly starts in the Blue print ending stage or in the realization stage
    2. <u>Support</u>
    Customer has already installed SAP & wants to give the work of maintaining those systems. This is support project
    There is no phases in it. Just receive the tickets, solve and send back to client.
    3. <u>Upgrade</u>
    Customer has SAP Version 4.6b and wants to update his version i.e. wants to go to Version 4.7. This is upgrade project
    4. <u>Rollouts</u>
    Customer has upgraded his version & wants to rollout country specific changes.
    This is rollout project
    Say a company is having branches in 3 to 4 countries.
    In One country they have already implemented SAP
    IF they wants to implement the same SAP in other countries of their branches they will simply follow the same SAP implementation policy (Rollout) how they have done for the first country just by changing the country specific settings and configurations.

  • Charms Process in Implementation Project

    Hello Gurus,
    I am part of an implementation project for where we are implementing various functionalities of Solution manager.
    Here we are in the process of implementing CHARMS in the Implementation Phase.
    So I have created a project of type 'Implementation' and has already activated Charms.
    Here the task list is already created and active
    Following are the issues which i am facing while creating a change request.
    1: If I create a change request of type 'SDCR' and authorize the change request, a normal correction of type 'SDMI' gets created automatically. But system throws an error 'No Maintenance cycle is open for the current system'
    I believe for a project of type 'Implementation' ,maintenance cycle doesnt get created, instead an implementation cycle gets created.
    So Let me know if  i have missed out any configuration. or if possible can u suggest me if there is any workaround for this?
    Regards,
    Anubhav

    Hi Raquel,
    Thanks for the reply.
    I have only activated BC Set 'SOLMAN40_CHARM_BASICFUNC_001' prior to activating CHARMS.
    After Activation Charms A project cycle of type 'SDDV' also got created along with the task list.
    But when I try to create a change request of type 'SDCR', it is automatically creating Correction of type 'SDMI'
    Also I had selected the correct Subject option 'Development (Implementation)' in Transaction SDCR
    Am I suppose to activate any other BC set?
    But why is it giving me error related to Maintenance cycle?
    Regards,
    Anubhav

    2. Even if u have activated the datasource & setup alos in Extract structure u didn't get the record it is showing zero records.
    3.After extraction datareconcillation errors ( mean that checking data of BW with source sytem data)
    for above step3 u have to choose proper transactions **
    <b>In Loading:</b>
    Loading data is very Importent .
    1.Currency translation errors,Arithematic errors .
    2. Error 4 .
    3.caller 01,caller 02 errors.
    4.short dump

  • Realization phase in Template/Implementation project

    Hello!
    We have completed our blueprinting in SM40 on a project which was created as a template project. Now to kick-off realization phase, should we create a new implementation project out of the template..or ..just configure the project as a template itself...
    What are the pros and cons? What is the right way of doing it..
    Appreciate any advise/inputs.
    Thanks.
    Mike

    Hi Mike,
    in the template project every customizing element has the attribute global / harmonized / local.
    Even if a rollout directly with the template project is possible (never heard of that), you would loose one of the greatest advantages of the global rollout functionality:
    When copying the template project into an implementation project, all customizing elements set as global are "locked" and can not be changed by the local support teams. The ones with attribute "local" can (details see attribute specification). Thus you ensure that local settings can be applied and global processes remain as defined.
    Next step is to centrally develop a new version of the template for roll-out, while your maintenance teams can work with the implementation project(s).
    Another decision is to use one Implementation project for all roll-out candidates (pro: all relevant documentation in one project; con: documents need to be well arranged for not to loose track) or several Implemenation projects for each roll-out candidate (con: scattered documentation; pro: easy overview per roll-out candiate).
    Hope this clarifies a bit...
    Regards
    Christoph

  • ChaRM Maintenance Project & Implementation Project - How to select ?

    Hi,
    I am having an Interesting issue.
    I have defined two ChaRM Projects, One is Maintenance Project (ZCHARMIDES) & One is Implementation project (ZCHARM_NC).
    Implementation project (ZCHARM_NC) I defined today itself & Maintenance Project I am using for last 2 months.
    In both the projects I have same logical component.
    Now When I am creating a Change Request & authorizing it, it is generating Normal correction based on subject. But by default its taking Task list M000000001 which belongs to Maintenance Cycle, But I want to select Implementation Project, how to select this.
    My issue is why system is not asking me to select project ( Maintenance & Implementation) even though the logical component is same.
    I want to select Implementation Project  - I000000114 for checking Normal Corretion.
    Regards
    Praveen Khot(PK)

    Hi PK,
    It depends on the subject which you are selecting. A normal correction type in the subject field is related to the maintenance project. And hence, when you have only one maintenance project with that landscape, it automatically gets assigned to that maintenance project.
    In order to select the implementation project, your subject would look like Development (Implementation) (unless customized) and only then the follow on correction type would be the normal correction in the implementation project.
    Per the standard functionality of ChaRM, you will not be able to see the pop up to choose amongst one of the project types for a CR.

    Sneha Vyas.
