What is the best practice to consume RMI Service

hi ,
i have rmi solution client server
i want to know which one is the best practice and more stable approach from one of the below.
1. initialize / consume the service once only
maybe can do it in static block
Example : static {
//some object = Naming.lookup("rmi://192.168.0.130/RMIServer");
2. Everytime client perform some activity and need to invoke rmi server
then consume the service
Example :
public String getQuote(String quoteNumber){
}

Esentially both.
Each time you do #2, but if it fails, then you do #1. You never know when its going to fail. failure is a normal part of TCP communication so be prepared to handle it gracefully as if its not even a failure.

What is the best practice for developing web service?

Hi All,
I'm a newbee to web services...
I was wondering what would be the best approach in developing a web service,
using tools or programmatic approach?
If I use WebLogic Workshop, am I tied to a vendor?
Is it possible for me to develop web services using workshop and deploy in
another app server..?
I would appreciate if somebody could give me a pointer to start.
I have already referred BEA's docs.
I'm still confused on a good starting point on the best approach to develop
protable web services.
Thanks in advance for any inputs.

K K-
You have a very valid point on the simplify or complicate matters. If you are
going for clean and not-so-time-centric code, then there are several different
programs and packages out there you can choose from.
Since you are specialized in J2EE, than the Sun package may be what you are looking
for. BEA's classes simplify much of the work you will be doing, but you could
emulate their classes or extend yours above the functions provided in theirs.
It all boils down to how much work are you willing to do.
If you are asking for more detailed, coding 'Design Patterns' to utilize, I would
wait for a few more posts from other folks as my work often requires me to utilize
the tools provided.

Eric,
Thanks for the response.
I was also looking at Sun's WSDP 1.1, which is more programmatic approach.
Some how, I feel being a J2EE developer, I should go on the direction
of the
programmatic approach.
Using the tools could simplify or complicate things. Also, the Workshop
samples import all weblogic specific packages.
My code looks so dirty with many vendor specific packages being imported.
Could you give me your suggestions for a clean and neat approach?
I would personally prefer to avoid the quick and dirty approach.
Thanks again.

The best approach in developing portable web services is knowing whatyou
are
planning on using them for as well as how much is willing to be spent,etc.
BEA's Workshop is portable to other frameworks, but the ease ofintegrating a
developed client or a developed server can very greatly. Even moreof an
issue
is migration from one framework to another. If you choose to developin
Workshop
and your company later deploys .Net solutions, some of your work mayhave
to be
redone unless the company is willing to keep portions of the 'old'system
around
until new versions of the service are available. However, Workshophas
several
ant tools available that would assist you in deploying to other appservers or
even a stand-alone application should you need cross framework abilities.
If you are just starting out in web services, http://www.webservices.org
is a
good place to start checking out vendors in the space.

Best practice for consuming web services

Hi
we are consuming web service in orchestration by "Add Generated Item".By using this option it creates 1 orch,1xsd file and some bindings.
we have different projects for schemas,maps and orchestration under our solution in visual studio.
Now i need to know that what will be the best practice for consuming web service in orchestration i mean in which project should i use "add generated item" (in orchstration project or in schemas project) coz it generates both 1 orch and 1
schema.
thanks

From a service orientation perspective you should abstract the service artifacts from the other artifacts. Otherwise it will be very difficult to update the service interface without affecting the other artifacts. For example you don't want to have to redeply
your entire application if only one field changes in the service you consume.
So I typically generate the items, remove the unnecessary stuff, and put them in a separate project.
Depending on the control you have over the services you want to consume, it would even be better to create another layer of abstraction. By that I mean create your own interface (schema) and map that one to the one the service exposes. This basically
is only necessary if you consume external services that are beyond your control. By abstracting the interface it exposes, you limit the impact of changes of that interface on the rest of your system. All changes are abstracted behind your own interface.
If you consume internal services, you can probably control the way the interface is defined. In a service oriented world all internal services expose a well known interface, based on the domain objects you have within your organisation.

What is the best practice for full browser video to achieve the highest quality?

I'd like to get your thoughts on the best way to deliver full-browser (scale to the size of the browser window) video. I'm skilled in the creation of the content but learning to make the most out of Flash CS5 and would love to hear what you would suggest.
Most of the tutorials I can find on full browser/scalable video are for earlier versions of Flash; what is the best practice today? Best resolution/format for the video?
If there is an Adobe guide to this I'm happy to eat humble pie if someone can redirect me to it; I'm using CS5 Production Premium.
I like the full screen video effect they have on the "Sounds of pertussis" web-site; this is exactly what I'm trying to create but I'm not sure what is the best way to approach it - any hints/tips you can offer would be great?
Thanks in advance!

Use the little squares over your video to mask the quality. Sounds of Pertussis is not full screen video, but rather full stage. Which is easier to work with since all the controls and other assets stay on screen. You set up your html file to allow full screen. Then bring in your video (netstream or flvPlayback component) and scale that to the full size of your stage (since in this case it's basically the background) . I made a quickie demo here. (The video is from a cheapo SD consumer camera, so pretty poor quality to start.)
In AS3 is would look something like
import flash.display.Loader;
import flash.net.URLRequest;
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.ui.Mouse;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.StageDisplayState;
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
// determine current stage size
var sw:int = int(stage.stageWidth);
var sh:int = int(stage.stageHeight);
// load video
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
var vid:Video = new Video(656, 480); // size off video
this.addChildAt(vid, 0);
vid.attachNetStream(ns);
//path to your video_file
ns.play("content/GS.f4v");
var netClient:Object = new Object();
ns.client = netClient;
// add listener for resizing of the stage so we can scale our assets
stage.addEventListener(Event.RESIZE, resizeHandler);
stage.dispatchEvent(new Event(Event.RESIZE));
function resizeHandler(e:Event = null):void
// determine current stage size
    var sw:int = stage.stageWidth;
    var sh:int = stage.stageHeight;
// scale video size depending on stage size
    vid.width = sw;
    vid.height = sh;
// Don't scale video smaller than certain size
    if (vid.height < 480)
    vid.height = 480;
    if (vid.width < 656)
    vid.width = 656;
// choose the smaller scale property (x or y) and match the other to it so the size is proportional;
    (vid.scaleX > vid.scaleY) ? vid.scaleY = vid.scaleX : vid.scaleX = vid.scaleY;
// add event listener for full screen button
fullScreenStage_mc.buttonMode = true;
fullScreenStage_mc.mouseChildren = false;
fullScreenStage_mc.addEventListener(MouseEvent.CLICK, goFullStage, false, 0, true);
function goFullStage(event:MouseEvent):void
    //vid.fullScreenTakeOver = false; // keeps flvPlayer component from becoming full screen if you use it instead
    if (stage.displayState == StageDisplayState.NORMAL)
        stage.displayState=StageDisplayState.FULL_SCREEN;
    else
        stage.displayState=StageDisplayState.NORMAL;

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

What is the best practice in securing deployed source files

hi guys,
Just yesterday, I developed a simple image cropper using ajax
and flash. After compiling the package, I notice the
package/installer delivers the same exact source files as in
developed to the installed folder.
This doesnt concern me much at first, but coming to think of
it. This question keeps coming out of my head.
"What is the best practice in securing deployed source
files?"
How do we secure application installed source files from
being tampered. Especially, when it comes to tampering of the
source files after it's been installed. E.g. modifying spraydata.js
files for example can be done easily with an editor.

Hi,
You could compute a SHA or MD5 hash of your source files on
first run and save these hashes to EncryptedLocalStore.
On startup, recompute and verify. (This, of course, fails to
address when the main app's swf / swc / html itself is
decompiled)

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

What is the best practice to display info of completed task in process flow

Hi all,
I'm starting to study BPM modeling with CE7.1 EHP1. Thanks to the tutorial and example on SDN site and I can easily build my own process in NWDS and deploy to server, start it, finish it.
I like the new runtime which can show a BPMN diagram to the processors. However, I can't find a way to let the follow up processor to review the task result completed in previous step. I'm more familiar with Guided Procedure, and know there is "Display Callable Object" which can used to show some info of a completed task when the processor/owner/admin/overseer click on a completed task. Where is the feature in BPM ? What is the best practice to show such task information in BPM environment.
For example, A multiple level approval process, the higher level approver need to know the comment written by the previous approver. Can he read this information from process flow ?
I think it is very important feature for a BPM platform. In Guided Procedure, such requirement can be done with Display Callable Object + View Permission, and you just need some coding for the UI. If BPM is superior to GP, I think there must be a way to achieve this, I just do not know how ?
Can anyone shed me some light on it ?

Oliver,
Thanks for your quick reply.
Yes, Notes and Attachment CAN BE USED for the purpose. But I'm still looking for a more elegant solution.
With the solution of using Notes/Attachment, the processor need to give input at two places : the task UI and Note/Attach , with similar or same data. It is really annoying.
Is there any SAP BPM real-world deployment ? None of customer has the requirement ?

What is the Best practice for ceramic industry?

Dear All;
i would like to ask two questions:
1- which manufacturing category (process or discrete) fit ceramic industry?
2- what is the Best practice for ceramic industry?
please note from the below link
[https://websmp103.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000409682008E ]
i recognized that ceramic industry is under category called building material which in turn under mill product and mining
but there is no best practices for building material or even mill product and only fabricated meta and mining best practices is available.
thanks in advance

Hi,
I understand that you refer to production of ceramic tiles. The solution for PP was process, with these setps: raw materials preparation (glazes and frits), dry pressing (I don't know extrusion process), glazing, firing (single fire), sorting and packing. In Spain, usually are All-in-one solutions (R/3 o ECC solutions). Perhaps the production of decors have fast firing and additional processes.
In my opinion, the curiosity is in batch determination in SD, that you must determine in sales order because builders want that the order will be homogeneus in tone and caliber, and he/she can split the order in diferents deliveries. You must think that batch is tone (diferents colours in firing and so on) and in caliber.
I hope this helps you
Regards,
Eduardo

Database Log File becomes very big, What's the best practice to handle it?

The log of my production Database is getting very big, and the harddisk is almost full, I am pretty new to SAP, but familiar with SQL Server, if anybody can give me advice on what's the best practice to handle this issue.
Should I Shrink the Database?
I know increase hard disk is need for long term .
Thanks in advance.

Hi Finke,
Usually the log file fills up and grow huge, due to not having regular transaction log backups. If you database is in FULL recovery mode, every transaction is logged in Transaction file, and it gets cleared when you take a log backup. If it is a production system and if you don't have regular transaction log backups, the problem is just sitting there to explode, when you need a point in time restore. Please check you backup/restore strategy.
Follow these steps to get transactional file back in normal shape:
1.) Take a transactional backup.
2.) shrink log file. ( DBCC shrinkfile('logfilename',10240)
The above command will shrink the file to 10 GB.(recommended size for high transactional systems)

> Should I Shrink the Database? .
"NEVER SHRINK DATA FILES", shrink only log file
3.) Schedule log backups every 15 minutes.
Thanks

What are the best practice in report design ?

Hi,
According to you, what are the best practices in report desing about layout, fonts and colors ?
Thks

Hi,
It all depends that what type of report you are designing and what tool you are using - WebI or Crystal.
And in WebI, if it is cross tab or Tabular report etc.
One most important thing is that what is client requirement. May be client does not like which is best practice.
On the base of my personal experience I will create few demo reports using different options - layout, colors and fonts and show them to client so that they may decide.

What is the best practice for creating primary key on fact table?

what is the best practice for primary key on fact table?
1. Using composite key
2. Create a surrogate key
3. No primary key
In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
I also found a relevant thread states that primary key on fact table is necessary.
Primary Key on Fact Table.
But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.
