Best Practice for SOA-oc4j using more than 4 GB

Hi,
is there any best practice how to use the SOA container with more than 4GB?
Oracle ships only java with 32 Bits...

If you need to modify the myRIO FPGA personality you have a few options.
The best option is to start with the myRIO FPGA sample project, add and remove components as needed and then build your bitfile. Any registers (LV FPGA controls / indicators) you don't modify will still work with the Advanced IO VIs and Express VIs. In order to use the new bitfile (FPGA Personality) you'll need to update the Open FPGA VI Reference in myRIO v1.1 Open.vi (LabVIEW 2013\vi.lib\myRIO\Common\Instrument Driver Framework\myRIO v1.0\myRIO v1.1 Open.vi).
After doing this any time you use a myRIO Express VI or Advanced IO VI it will use your custom bitfile. Any peripheral channels you've left in place will continue to work. Any channels you've removed will still show up in the VIs, but will not work (they will probably throw errors at runtime) and any new channels you added will not show up in the VIs. For new channels you'll need to use the FPGA Read / Write nodes to read and write the configuration and data register you created in the FPGA personality. These changes will persist on that computer until you change the Open FPGA VI Reference back to the original bitfile.
Let us know if you have questions about any of this.
Thanks!

Best Practices for multiple authors using single project?

We are having many issues, particularly with moving, renaming, and multiple check out warnings. We have a single project with many authors and it seems like RH is not designed to work that way. There is an article in the RH devnet-archive in an article entitled "Sharing RoboHelp Project Among Multiple Authors" that says"
"At first there may be the temptation to let every author work on every file in a project. This is certainly not a best practice. Regardless of source contraol, it is always best to designate certain authors as owning certain content-related sections, folders, or topics within a project -particulary at the folder level."
This statement, and our experience seems to indicate that RH is not a true CMS as we had envisioned. What are the best practices for this scenario to avoid stepping on each others toes and having problems with source control.

I have moved this to the source control forum for the gurus there to answer.
Meantime I must admit I read that statement the same way as you first time. However, on rereading I think what the author is saying is not that what you want cannot be done, rather it is best practice to guide authors to work in discrete areas.
I will leave it to the author or another guru to give you a more complete answer.

Best Practices for Team Collaboration using Adobe Captivate

With a team of 6 Instructional Designers, how can Adobe Captivate be approached where we can collaborate while producing e-learning material while maintaining a consistent look and feel of the e-learning we produce?
What are the best practices for a team of 6 IDs working and creating e-learning material in Captivate? Is there anything build-in that allows us to connect to the same libraries, templates, etc to share?
Please advise.
Thank you!
Susanne

Only some tips, never collaborated with someone else, being the solo teacher. You didn't mention which version you are using, what I write here is meant for CP7.
Be sure to prepare a theme and/or a template that will be used by everyone. A theme consists of master slides, object styles, skin editor. Master slides can have custom navigation shape buttons. In a template you can eventually also prepare different slides with placeholders, and eventually advanced actions etc. For CP6 and earlier that is the only way to reuse advanced actions, in Captivate 7 you can export shared actions that can be imported in any project for reuse.
A feature that few users know about are the external libraries. You can open the library of any project as an external library in another project. That is a good idea to store assets that you want to use in different projects: images, audio clips, video clips, eventually equations. The shared actions in a library can not (yet?) be used in another project however.
If you are on CP7 you have automatically the roundtripping with source Adobe Photoshop files and source Audition files, both from CC. That can also make collaboration lot easier if those assets are prepared in those applications. Will not expand on that, because I'm not sure you have the Creative Cloud applications.
Those are my two cents.

Best Practices for creating PDFs using PLPDF?

Does anyone have any suggestions for Best Practices in making PDF files using PLPDF?
I have been using it for about a month now, and the best that I have come up with is to use MS Access to prototype the layout of a report. Once I have all the graphics areas and text areas lined up how I would want them, I then write PLSQL code to create a procedure which is called from an HTMLDB page. MS Access is handy in that it provides the XY coordinates for each text area and graphics area. It also provides the dimensions of the respective cells. So long as I call plpdf.Init('P', 'in', 'letter') at the beginning of the procedure, both my MS Access prototype and my plpdf code are both using inches - this makes the translation relatively easy.
Has anybody found anything else easier/better?
Regards,

You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
So that it won't ask for password.
Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information

Best practices for building menus using resource bundles?

Greetings; I am curious to find out what the current best practices people are using to build menus/menu bars using resource bundles, specifically ListResourceBundle.
What I am trying to figure out is how best to write my Swing application so it does not need to know what menu items it needs to grab from the resource bundle.
The only idea I have come up with is this:
class MyBundle extends ListResourceBundle {
private Object[][] contents = {
{"menubar", { {"menu.file.item", "blah"}, ....} }
}Inside the GUI class:
Object[][] menubar = resourceBundle.getObject("menubar");I would then iterate over the menu bar items and build the menu. I would have to use a naming scheme and then parse appropriately to know when to start a new menu, when a submenu occurs, etc.
Is this the common practice, or does anyone know of a more clever way of doing this? I've searched various FAQs and googled about, but I have yet to come across any sort of tutorial or page that covers this.

Anyone have any input on this? Am I close to the solution people are
using out in real production environments?

Best practice for modelling rediects using the threat modelling tool

I'm in the process of modelling systems using the threat modelling tool.
There services in question do a lot of redirecting and handing off to one another on the client side, including things like ACS and identify providers.
If Web App A redirects to Web App B what is the best way to draw this?
1) App A (process) > HTTPs redirect > browser > request > App B (process) or
2) Can I just model it as HTTPS from A to B?
Obviously 2 simplifies diagrams hugely , but does that then exclude a range of potential threats or does the tool cater for this implicitly?

Storing documents outside the web root and using
<cfcontent> to push their contents to the users is the most
secure method.
Putting the documents in a subdirectory of the web root and
securing that directory with an Application.cfm will only protect
.cfm and .cfc files (as that's the only time that CF is involved in
the request). That is, unless you configure CF to handle every
request.
The virtual directory is no safer than putting the documents
in a subdirectory. The links to your documents are still going to
look like:
http://www.mysite.com/virtualdirectory/myfile.pdf
Users won't need to log in to access these documents.
<cfcontent> or configuring CF to handle every request
is the only way to ensure users have to log in before accessing
non-CF files. Unless you want to use web-server
authentication.

Best practice for standard security role

Hi, I'd like to know which is the best practice for standard role use, some people tell me that a standard role should never be used, that a copy must be made and assign the users to the copy, but then, why should SAP bother creating the standard role?

They are provided as a template for you, and you can copy them into a different namespace and make changes there before generating the profiles and authorizations.
Why you should use a copy of them is because SAP will also update them sometimes. If transactions change in the standard menues with SP's and upgrades, then you will find them in transaction SU25.
If you do a search on "standard AND roles" in the SDN then you will also find more detailed infos and opinions on the use of them.
Cheers,
Julius

Best practices for folder structure in SOA Project

Actually, In my project, I have more than 10 BPEL process and several DBAdapters and some HumanTasks. For each BPEL process, JDeveloper creates .bpel, .componentType, wsdl files. For DBAdapters JDeveloper creates lot of files, and same for HumanTasks as well.
By default Jdeveloper puts all these files in root directory of the Project. It looks messy having 100's of files in root directory.
How can I organize all these files?
What are the best practices for folder structure in SOA Project ?
Thanks

Yes Yatan. I did noticed that Polling service WSDL disabled in EM . But I want to try this approach beacause I want to move all database related stuff to one composite. I have another composite with 3 BPEL Processes. One BPEL queries external webservice and save the response in DB. One BPEL just fires the first Process(Query) and respond to caller with an unique id. I have Another BPEL which keeps polling on database for 5 sec(I'm using PICK Activity), if there is any new record in database it will retrun to caller. If no new records in database, returns empty to the caller after 5 sec.
If I put all these in one composite, having lot of files in root directory, the composite really looks very messy.
As you said, I want to have 2 composites. First Compoiste will have 3 BPEL processes, and 2nd Composite will have DB Polling and DB Save. I will have another project for MDS to store XSDs.
So because I can't have Polling service as exposed service, I have to keep Polling service in the same Composite where the BPEL is. Now again it goes back to Big and messy project.
Is there any way I can separate all DB related including polling in a separate Composite ?
Thanks

Using more than one PU and PC for the same database

I have a scenario described here: [http://www.seamframework.org/Community/UsingTwoParallelNestedConversationsWithParentAtomicConversation|http://www.seamframework.org/Community/UsingTwoParallelNestedConversationsWithParentAtomicConversation]
which uses Seam, EJB3, JPA, Hibernate, Richfaces (modalPanel) and JSF.
The question I have is the following:
is there any negative consequence (memory consumption, performance hit, etc.) of using more than one persistence unit in the persistence.xml that points to the same EntityManagerFactory? I was thinking of having one PersistenceContext (Seam-managed PC - an extended PC which is conversation-scoped) which uses one PU and reserving the other PC for the modalPanel forms and backing beans (SFSBs).
The reason I needed to use this solution/approach is so that when using Hibernate MANUAL flush with SMPC, I can achieve isolated synchronization of the PersistenceContext without updating values in the modalPanel forms and vice versa.
Any tips on best practices or alternative solutions? thx.
persistence.xml snippet:
   <persistence-unit name="boBETS">

   </persistence-unit>What happens if I were to have 10 PUs and 10 PCs in the same app? Whether they're all pointing to same DB or not. What's the consequence of using "too many"?

Yes, you can use multiple iCloud accounts in multiple User Accounts on one computer, but, as you know not multiple iTunes Match accounts. Keep in mind that the two services are not the same.
Since you've posted your question to the iTunes Match forum, which it really doesn't pertain to, you might want to also post it to the iCloud on my Mac forum.

Best Practices for Using Photoshop (and Computing in General)

I've been seeing some threads that lead me to realize that not everyone knows the best practices for doing Photoshop on a computer, and in doing conscientious computing in general. I thought it might be a good idea for those of us with some exprience to contribute and discuss best practices for making the Photoshop and computing experience more reliable and enjoyable.
It'd be great if everyone would contribute their ideas, and especially their personal experience.
Here are some of my thoughts on data integrity (this shouldn't be the only subject of this thread):
Consider paying more for good hardware. Computers have almost become commodities, and price shopping abounds, but there are some areas where spending a few dollars more can be beneficial. For example, the difference in price between a top-of-the-line high performance enterprise class hard drive and the cheapest model around with, say, a 1 TB capacity is less than a hundred bucks! Disk drives do fail! They're not all created equal. What would it cost you in aggravation and time to lose your data? Imagine it happening at the worst possible time, because that's exactly when failures occur.
Use an Uninterruptable Power Supply (UPS). Unexpected power outages are TERRIBLE for both computer software and hardware. Lost files and burned out hardware are a possibility. A UPS that will power the computer and monitor can be found at the local high tech store and doesn't cost much. The modern ones will even communicate with the computer via USB to perform an orderly shutdown if the power failure goes on too long for the batteries to keep going. Again, how much is it worth to you to have a computer outage and loss of data?
Work locally, copy files elsewhere. Photoshop likes to be run on files on the local hard drive(s). If you are working in an environment where you have networking, rather than opening a file right off the network, then saving it back there, consider copying the file to your local hard drive then working on it there. This way an unexpected network outage or error won't cause you to lose work.
Never save over your original files. You may have a library of original images you have captured with your camera or created. Sometimes these are in formats that can be re-saved. If you're going to work on one of those files (e.g., to prepare it for some use, such as printing), and it's a file type that can be overwritten (e.g., JPEG), as soon as you open the file save the document in another location, e.g., in Photoshop .psd format.
Save your master files in several places. While you are working in Photoshop, especially if you've done a lot of work on one document, remember to save your work regularly, and you may want to save it in several different places (or copy the file after you have saved it to a backup folder, or save it in a version management system). Things can go wrong and it's nice to be able to go back to a prior saved version without losing too much work.
Make Backups. Back up your computer files, including your Photoshop work, ideally to external media. Windows now ships with a quite good backup system, and external USB drives with surprisingly high capacity (e.g., Western Digital MyBook) are very inexpensive. The external drives aren't that fast, but a backup you've set up to run late at night can finish by morning, and if/when you have a failure or loss of data. And if you're really concerned with backup integrity, you can unplug an external drive and take it to another location.
This stuff is kind of "motherhood and apple pie" but it's worth getting the word out I think.
Your ideas?

Best practices for using Query Browser

Hi,
I started getting along with "Query Browser" option to embed data directly from Bex queries to the dashboard.
I am looking for the Best practices which are recommended and needs to be followed from performance point of view and from reporting point of view.
I went through some of documents but was not convincingly sure about the measures which they suggested.
So, would be thankful for any help points or documents received in relation with it.

Jaywant Kulkarni.

Hi JK,
All above links are given general rules and tips & tricks to boost your dashboard performance.
Keep the dashboard simple and clean, dashboards are for summarized level not to the detailed level.
try to understand the KPI for the client based on the write your model in paper first and go through the dashboards.
Maximum of number of rows allowed by the dashboard is 512, you can increase the rows but that too hampers your dashboard, if the result set of the query is too big.
Connections i have seen people using more than 10 - 15 connections into the dashboards, but these many connections. really your dashboard will take time to retrieve the data.
Things you need to consider:
- Reduce the components in your DD.
- Make the font name similar across the dashboard.
- Enable the option show loading status in document properties, this will increase your loading time.
- Use refresh type as "Refresh after components loaded".
- Use simple formula as if-else & sum,indexes.
- Remove formatting in your query's.
These are the few things you can consider while designing the dashboard. Do search in scn and blog there lot many tips and tricks are available.
Regards,
Suman

What are the best practices for using the enhancement framework?

Hello enhancement framework experts,
Recently, my company upgraded to SAP NW 7.1 EhP6. This presents us with the capability to use the enhancement framework.
A couple of senior programmers were asked to deliver a guideline for use of the framework. They published the following statement:
"SAP does not guarantee the validity of the enhancement points in future releases/versions. As a result, any implemented enhancement points may require significant work during upgrades. So, enhancement points should essentially be used as an alternative to core modifications, which is a rare scenario.".
I am looking for confirmation or contradiction to the statement "SAP does not guarantee the validity of enhancement points in future releases/versions..." . Is this a true statement for both implicit and explicit enhancement points?
Is the impact of activated explicit and implicit enhancements much greater to an SAP upgrade than BAdi's and user exits?
Is there any SAP published guidelines/best practices for use of the enhancement framework?
Thank you,
Kimberly

JSF - Best Practice For Using Managed Bean

I want to discuss what is the best practice for managed bean usage, especially using session scope or request scope to build database driven pages
---- Session Bean ----
- In the book Core Java Server Faces, the author mentioned that most of the cases session bean should be used, unless the processing is passed on to other handler. Since JSF can store the state on client side, i think storing everything in session is not a big memory concern. (can some expert confirm this is true?) Session objects are easy to manage and states can be shared across the pages. It can make programming easy.
In the case of a page binded to a resultset, the bean usually helds a java.util.List object for the result, which is intialized in the constructor by query the database first. However, this approach has a problem: when user navigates to other page and comes back, the data is not refreshed. You can of course solve the problem by issuing query everytime in your getXXX method. But you need to be very careful that you don't bind this XXX property too many times. In the case of querying in getXXX, setXXX is also tricky as you don't have a member to set. You usually don't want to persist the resultset changes in the setXXX as the changes may not be final, in stead, you want to handle in the actionlistener (like a save(actionevent)).
I would glad to see your thought on this.
--- Request Bean ---
request bean is initialized everytime a reuqest is made. It sometimes drove me nuts because JSF seems not to be every consistent in updating model values. Suppose you have a page showing parent-children a list of records from database, and you also allow user to change directly on the children. if I hbind the parent to a bean called #{Parent} and you bind the children to ADF table (value="#{Parent.children}" var="rowValue". If I set Parent as a request scope, the setChildren method is never called when I submit the form. Not sure if this is just for ADF or it is JSF problem. But if you change the bean to session scope, everything works fine.
I believe JSF doesn't update the bindings for all component attributes. It only update the input component value binding. Some one please verify this is true.
In many cases, i found request bean is very hard to work with if there are lots of updates. (I have lots of trouble with update the binding value for rendered attributes).
However, request bean is working fine for read only pages and simple binded forms. It definitely frees up memory quicker than session bean.
----- any comments or opinions are welcome!!! ------

I think it should be either Option 2 or Option 3.
Option 2 would be necessary if the bean data depends on some request parameters.
(Example: Getting customer bean for a particular customer id)
Otherwise Option 3 seems the reasonable approach.
But, I am also pondering on this issue. The above are just my initial thoughts.

Best practice for the use of reserved words

Hi,
What is the best practice to observe for using reserved words as column names.
For example if I insisted on using the word comment for a column name by doing the following:
CREATE TABLE ...
"COMMENT" VARCHAR2(4000),
What impact down the track could I expect and what problems should I be aware of when doing something like this?
Thank You

Whatever benefits you may get from naming the column COMMENT rather than, say, CMNT or EMP_COMMENT (if the table is called EMP) will be insignificant compared to the extra debugging you will certainly need.
