Where to Install in Production Environment

[Former Member]

Dear EHS Experts,

Please enlighten me if a dedicated PC is a necessity in installing WWI Generation Server? I have read that it is and I just wanted to know if it also can be made in windows server. During my testing, i have noticed that you can't completely save the template without error if you have edited it in the different windows PC. For example, you installed WWI generation server in PC1.a and you tried creating and saving the template in PC1.b. The creation and saving should be done in PC1.a to avoid the error. This is only my observation and if I'm going to relate it using windows server, the creation and saving should also be done there. Hope to hear from you. Thanks in advance!

Kind regards,

Mark

Dear Mark

I am not sure if I understood your topic. Therefore the other way around:

1.) if you would like to "manage" (develop, enhance etc.) a WWI template you use a local WWI client installation (any WWI developer needs that)

2.) There are some OSS notes available regarding sizing and other topics of WWI. The number of servers depends on size of your company and the modules in SAP EHS which you use or plan to use. And yes: you can use "virtualization software" on the gen server so that on one hardware you can prepare more than one server (please check WWI cookbook and other WWI references on SAP marketplace)

3.) to use "Report from template" functionality you would normally prepare a local WWI set up; with higher SAP release you can avoid this set up; the "Report from template" functionality will be then dispatched to the GenServers and you will get only the result passed back to your local client so that you can view the result of the generation (clearly: you need more gen servers ! depending on the number of users of SAP EHS interested in WWI reports; the same is true for display in CG50/CG54); if you develop WWI layouts you need a local WWI installation in any ase.

We can differentiate that: on Dev system you would need X servers; one part of the servers to deal with standard EHS topics (as e.g. SDS/MSDS, SOP etc. report) and the other to deal with GLM report (if you use GLM); In Qual system you would use then may be 2*X servers and in Prod depending oon your landscape / size of company etc. 3*X up to 4*X (whatever number X represents); SAP does not provie here clear guidelines; but there are may nice tools available now to check what is going on on WWI server (please check SAP online help; SDS/MSDS distribution part).

As mentioned e.g. in http://scn.sap.com/thread/3404443 it is critical that the general WWI installation by server is the same. Taking into account real life: if you are not taking care of that you will have very strange results in WWI (and you will get frustrated becuase you can not explain easily the results !)

May be check: http://scn.sap.com/docs/DOC-41109 and reference there in to WWI cookbook and other WWI topics.

Hope this helps

Dear CB,

Thank you for sharing your ideas. I believe when you say local WWI client installation, it pertains to the configuration of WWI Generation server in a local PC. If my understanding is correct, does this mean that it is mandatory? What i meant is, WWI Generation Server must always be configured in a local PC therefore requiring a dedicated PC that is up all the time (per cookbook)? Or can it also be installed/configured in a windows server therefore no dedicated PC is required?

Right now i have installed/configured WWI generation Server in my local PC and its working fine. I have two profiles in my local PC. Lets take it PCa and PCb.  I have configured WWI generation server in my PCb. If i update or create a template in PCb, its working fine. I have tried to update/create a template in PCa, its not completely saved. My own conclusion based on this observation is that the creation or update of the template should be made where WWI generation is configured.

Now i'm relating it if the business wants to install/configure WWI generation server in a windows server. Based on my own conclusion, the update or creation or update of the template should also be made in windows server. Though i haven't tested this yet, i think the end user's PC who will create or update the template should have WWI generation server installed/configured in his/her PC on top of the installation and configuration of WWI generation server made in window server and only ensure it is done the same (name of RFC, path are the same etc). Does it sound correct? Please enlighten me. Thanks much!

Kind regards,

Mark

Dear Mark,

a.) local WWI installation: do not prepare a "local" gen server installation; it should be a "simple" local installation (to maintain, enhance, develop etc. WWI layouts). During WWI set up you are asked for in which way you would like to install the WWI. Even if you succeeded to install WWI on your client as "gen server" this is the "wrong" approach. A gen server (in contrast to local WWI installation) must be up and running 24 hours 7 days a week in prod without any disturbance !

b.) your understanding is not correct (my own conclusion based on this observation is that the creation or update of the template should be made where WWI generation is configured.); WWI layout are developped locally and not on WWI gen server

c.) Based on my own conclusion, the update or creation or update of the template should also be made in windows server.  => no; WWi layouts are devlopped locally and not on gen server

d.) i clearly assume that no ! end user will update templates (I do not know one end user how would be able to do so; this is a clear development step). And again: you are not correct. Local WWI installation is used for template development; gen servers are prepared to take care e.g. regarding SDS distribution, GLM printing etc. and must be up and running 24 hours 7 days a week; a local WWI installation is used only for WWi layout development and normally a very low number of persons in an IT company do really know what they are doing regarding WWI layout)

But you need on the top a "local" WWi installation for any end user. This is needed to execute "Create Report from template" by end user and it is needed in context of CG50/CG54 to support the end user. Starting with EnhPack 3 you have on the top the possibility to use additional WWI servers for "Report from template" and "CG50/Cg54" activities of end user. Here I have no experience. Up to now I haven'T had contact with one company using this approach (may be check http://scn.sap.com/thread/1850730).

Check e.g. http://www.slideshare.net/shivaprasadd/ehs-wwi-cookbooken

Chapter:  4.5. Don't use option "Install Generationserver"

The whole topic of set up etc. of Gen Servers is explained in this document very well (be aware of the fact that may be on SAP Marketplace a newer version of this document might exists; but it is a good starting point).

Depending on the size of your company, business running etc. normally between 20 - 50 persons need local WWI installation (as part of SAP Gui installation) to use "Report from template" etc.;

Hope this helps you to get a better picture.

=> use option "Workstation for Editing Report Templates "

PPS: may be I misinterpret your doubts but I have the feeling that you "misinterpret" the layouting topic a little bit; Layouts are developped locally; the result is passed back (via SAP GUI and local WWI installation) to SAP EHS (to be stored in SAP DMS); Therefore a layout is stored as document in SAP DMS (not on local WWI nor central WWI installation). Document type is (if I remember correct) SBV. The topic of SBV, SBR, SBE is handled in different threads and in one of my threads I refer to a very nice SAP online help picture (http://help.sap.com/erp2005_ehp_02/helpdata/en/db/9c07c414fb11d494b9080009b98822/frameset.htm); which you can use to understand what happens during layout template "editing", what happens on gen server and how are the data retrieved mixed and pushed back so SAP EHS to either generate a "SBR" or a "SBE".

Dear Mark,

the general practice to install WWI in prod system is on a dedicated server which has to be up and running 24 hours. In addition, it must be also installed locally to generate reports.The WWI on the main server triggers and balances the load on the generation server.

Dear Dhinesh,

Just curious with your comment above. When you say "dedicated server", it is not only confined to PC server? How about Microsoft Window server? I think the latter is more practical to ensure it is running 24 hours daily and you dont need to open a PC 24 hours everyday. Can you please advise? Thanks much!

Kind regards,

Mark

P.S. - Other comments from other EHS Consultants are welcome

Dear Mark,

You are right. It can be a windows server where u install this wwi stuff. The objective is that, the system must be running 24/7 like u use ur other servers for everyday activity.
