To choose between one heavy EJB or many light ones

Hi,
We were just wondering whether an app server (like the latest versions of Weblogic
or IBM's Websphere) would prefer one heavily-accessed stateless EJB when compared
to a set of several modularised ones (all stateless again). How would performance
be affected in the two cases?
The first case would see several instances of the same EJB which would act as
a controller. The second case would see a modularised view of the businesss logic
and the client requests would be more tightly-bound to the business logic.
Please base your responses primarily with performance in mind. We need to make
a design decision based on inputs we receive.
Thanks and regards,
Kishlay Baranwal

Don't compromise on object oriented design (You might end with more than
performance problems). Stateless session beans scale very well (especially
on Weblogic) since they are pooled.

Hello, i have a question. I've got one .mov video and one .mp4, both 3 minutes long. Now I want to burn them on one single dvd, and a menu (if possible) so i can choose between them. Is this possible?

You could use iMovie if you own it. Look here for an example...

What to choose between MM/SD / GDM...?

Hi ALL,
I have got experience in PP-PI AND QM module of around one and half years.Now there is a requirement in which i need to choose between Materials Management/ Sales and distribution and Global data Management.The project in which i will be asked to work has about 60% SD related work and rest 40% consists of all other modules together.
I don't have much idea about these modules. Can anybody plz suggest which is better to chose among these 3 modules taking into consideration the future prospects.
What is the scope of GDM in future and what will be easier for me to grasp MM or SD.
Your views and suggestions regarding are most welcome.
Regards,
Ameya Khanwalkar.

Hi ,
Thanks for the suggestion.My domain experience is of 3.3 years in Production planning & Control.
Also i have heard that there are lot many people as SD/MM consultant as compared to PP/QM consultant.Is that so ?
So can anyone advice if it is better to stay with PP/QM or to gain some sort of hands on MM/Sd as well
Thanks

Today, I had to choose only one mail. Really a shame for Blackberry.

I'm a french Blackberry user for many years. Today, on my Torch, I was asking by Blackberry to enter my password.No more mail on my phone... Blocked.
I have a smartphone, a kind of hardware, and I did not know that Blackberry can block my mails !!!
Strange, is'nt it ?
Is it legal ?
OK. I did it.
What a surprise after that !! I had to choose only one mail address... so I have to choose between my mails and my pro planning via Yahoo.... (I bought a small soft fo that)
I bought a Blackberry for security, well built phones and so...
Now, I was asked to choose for a restricted service, decided by Blackberry.
I have no choice, or my mails are blocked...
It's really a shame and not fair.
Of course, no way to reach them directly.
If Blackberry don't move, I will choose others....
To be free today is really a challenge...
Solved!
Go to Solution.

If you are in the same situation, contact me.
Pour les français, je n'ai pas réussi à avoir une identité qui fonctionne sur le site de Blackberry France...
Pour ceux qui ne comprennent pas bien mon anglais moyen :
Je n'ai plus de mails sur mon torch depuis 16h30 aujourd'hui.
Blackberry m'a demandé d'entrer mon mot de passe....
Ensuite, je n'ai plus eu le choix, sois-disant avec mon abonnement, je n'avais droit qu'à une adresse mail !!!
Cela fonctionnait depuis des mois et je n'avais pas d'abonnement....
Il fallait que je choisisse entre mes mails et mon planning professionnel géré par Yahoo car Blackberry n'a jamais été capable de gérer des passerelles avec Lightning, cf Thunderbird.
Est-ce pour imposer leur softs ? Est-ce pour faire payer plus ???
Dans tous les cas, ils m'empêchent de travailler normalement et le blocage des mails est totalement abusif.
Si vous êtes dans le même cas, n'hésitez pas à poster sur le forum.
Plus nombreux nous sommes, plus nous aurons de poids.
Bien à vous,

Can I set FIREFOX to choose between two different homepages or websites?

I know that Firefox will open any number of web sites when you start it. I want to have the ability to choose between opening a preset number of sites and just one. For instance at the beginning of the day I want all my banking sites available when I start. Later in the day I want to open only say, Google. Is there any way to have Firefox do that?

Hi Suresh,
If you do changes in Finance and want to send data in Sales , you can use LOOKUP /DESTIANTION_APP -script logic or ABAP logic.
To have seamless flow, you need to take care of security.

I am going to buy a macbook pro 15" but i can't choose between glossy or anti-glare

i am going to buy a macbook pro 15" with the 8gb ram and all that jazz but i can't choose between the glossy or anti glare they both will apply to my daily use but i cannot decide. is it possible to pick lets ay the glossy one then if i dont like it switch to the anti-glare or not ?

You can replace the screen later on, but at a cost.
Best bet would be to go to an apple shop and have a look at the 2 side by side and decide for yourself; if there was 1 that was better than the other, apple wouldn't give you the choice.
p.s. on a personal note I like the glossy one better. nicer picture IMO

While listening to music in my car, I don't have the option to choose between bluetooth and headphones anymore. Why?

On IOS 6 and earlyer, I use to be able to choose between the bluetooth or the headphone jack. Now, I can only play music true my bluetooth and I can't pause the music. Anybody has a solution?

Basic Troubleshooting Steps when all else fails
- Quit the App by opening multi-tasking bar, and swiping the App upward to make it disappear. (For iOS 6, holding down the icon for the App for about 3-5 seconds, and then tap the red circle with the white minus sign.)
- Relaunch the App and try again.
- Restart the device. http://support.apple.com/kb/ht1430
- Reset the device. (Same article as above.)
- Restore from backup. http://support.apple.com/kb/ht1766 (If you don't have a backup, make one now, then skip to the next step.)
- Restore as new device. http://support.apple.com/kb/HT4137 For this step, do not re-download ANYTHING, and do not sign into your Apple ID.
- Test the issue after each step. If the last one does not resolve the issue, it is likely a hardware problem.

ADF BC: Choosing between two identical DB schemas on application startup

Hi,
We want to provide users with capability to choose between two identical db schema.
Anu idea how to do this ?

Cvele wrote:
Thanks a lot ! My pleasure.
One question: datasource name entered by the user (on the login form) is a JDBCDataSource property value for the Application module Configuration (which connect trough JDBC DataSource), correct ?Yes.
If so, then, we still must define two different sets of App Module Configurations, one for each DB schema, correct ?No. I'm not suggesting that you implement your UI like the demo that I forwarded. It might not be appropriate for your user to type in the datasource name, but the same code would be required to make the datasource name change work. Rather than getting the datasource name from the HTTPRequest and setting on the session where the custom sesison cookie impl and env info provider access you, for your solution that datasource value might come from some other place that the end-user doesn't directly type in.
Otherwise:
1. we cannot have two different datasource names, correct ?The example I forwarded should allow you to enter different JNDI names, so those would be different datasources.
2. in case of one Configuration – what is a way to define (at deployment time) username/password for each of those two schemas ? Is this correct ?The username/password information is encapsulated inside the Java EE container when you define the datasource. The application doesn't know that information and doesn't have to provide it when you are using a JDBC datasource by JNDI name.
On the other hand, what confuses me, is a fact that you say:
“You wouldn't use different configurations” And really, you example attached to me have just one App module Configuration (datasource name = jdbc/scottDS), which connect through dataSource.
Wondering what a user can enter as datasource name, except jdbc/scottDS ?I forget whether in my example I configured another datasource, but the user could enter the name of any available JNDI name for the datasource on the Java EE container.
Again, I don't suggest necessarily that you let the end-user type it in, that was just how I built the demo since I quickly evolved it from the other dynamic credentials demo that accepted the username and password from the end-user.

GarageBand has detected a possible conflict between one or more third party

I have 200 computers that when you launch GarageBand 3.0.5 it comes up with the error:
GarageBand has detected a possible conflict between one or more third party MIDI or audio drivers
Our image is basically 10.5.6 with mainly Adobe CS 3 suite. No other sound programs or anything sound or video related was installed besides iLife 06 and I'm not sure what is causing the issue. I have tried reinstalling iLife 06 and run all updates available from Apple and repairing permissions. I have went through the plugins in /Library/Audio folder and haven't had any luck at all.
What gets me is under the admin account I have it working fine by removing the default emagic plugin in /Library/Audio/ etc.. but if I log in as a regular user without admin privileges i get the error.
I have tried deleting pref files in the users Preferences folder, but I just can't find a workaround.
It kinda seems to be like a permissions issue since the Admin account works, but I have tried pushing permissions 777 to /Library/Application Support/ and to /Library/Audio and to /Applications/Garageband.app and still no results.
I was blaming an Apple update because things worked fine before, I'm not sure what caused it. I reinstalled the combo update and that didn't help either.
I reformatted and installed 10.5 and upgraded using the combo updater to 10.5.6 and installed iLife 06 and installed all available updates from Apple like I have in the image and things work fine.
But I need to get this working on our image.........Anyone have any ideas as to what could possible be the issue and might know a fix????
Google searches the solutions I have found are repairing permissions and deleting plugins. I have tried repairing permissions and have no plugins besides the defaults, but I have already removed the emagic one and nothing else is in there.
Thanks!!

To get me through the year I deleted a bunch of Microsoft Office Receipts in /Library/Receipts and it fixed the issue.
I have no idea why, deleting a receipt from another app shouldn't affect anything, but it worked. I spent many hours trying to figure out a solution and this worked!
We are running iLife 09 now and no issues so far!

Why are PS and SG asking me to choose between purchasing the product or a 30 day trial?

I have the one-year Creative Cloud Subscription and I downloaded several apps like Photoshop, Premiere Pro, and SpeedGrade.
However, when I start up Photoshop and SpeedGrade I had to choose between purchasing the product or register for a 30 day trial.
Anybody who knows why?

Thanks a lot! I will give it a try!

Difference between one step approval and N-step approval?

Hi Experts,
Can anyone tell what is major difference between one step approval and N step approval?
I guess its only one person will approve incase one step approval and where as in the N-step approval a shopping cart can be approved by many users under some prerequistes right??
can some one provide me some hints on this.....
how does it make a difference in workflows and how to mantain the settings for this in the SPRO. for this one to setup a one-step and N-step approvals. what are points to be taken care while setting up this?
Please can some one clarify me on this
Regards
Sairam.
I

Hi,
1 step approval - Number of approvals will be 1
n step - number of approvals greater then 2(since std approval workflow present till 2 level)
The general customising steps for Workflows apply to both of them (like SWU3 customising.event linkage etc) but other then that for,
1 step approval -
-->Need to activate the starting conditions
-->Agent assignment to be done seperately for the Approval task
(Also the N step workflow can be used as 1 step workflow with number of approvals being set to 1 through the Logic in the badi.)
N step approval -
-->to be implemented through BADI BBP_WFL_APPROV_BADI .This BADi actually determines the Agents/approvers for the workflow.
-->As per my exp,this workflow is very unstable and for few updates,you may have to apply number of notes(e.g. Approval status not updated properly,graphical preview not visible properly etc)
BR,
Disha.

Need your help choosing between 2 audio/midi interface for logic

Hi, new member here. I just signed-up just to ask for your recommendations.
I am looking to buy either the Cakewalk UA-4fx (http://www.sweetwater.com/store/detail/UA4FX) or Tascam US-122mkII (http://www.sweetwater.com/store/detail/US122mk2).
Do you have any advice on which one to get (or a third alternative if you know something that's similar but better)?
I'm mainly looking to record from my Roland Fantom X keyboard to my Macbook (using Logic Pro). The effects/filters on the Cakewalk device is not that important to me (since I can use software effects), but the quality of sound is the most important. Also, ease-of-use and compatibility with Logic Pro is important. The device also must include MIDI-in/MIDI-out in addition to 1/4 inch direct line in for my synth. (I plan on using Midi-In/Midi-out with MainStage in Logic Studio). Not looking to spend too much more than $100.
I think I read in a review that even though the Cakewalk UA-4fx has 2 inputs, it can only record 1 at a time. Is the same true of the Tascam or can it record 2 simultaneous tracks?
But in short, sound quality AND compatibility with Logic Pro and MainStage are the main concerns. Does anyone have advice on choosing between the 2 or a third option if you know of one?
Thanks in advance!

Hello -
It's been suggested to avoid, if possible, USB-based audio devices. My humble suggestion? I'd consider MOTU products. I own three MOTU audio devices (2408-MK3, 828-MK3 & 828-MK2) and all work just fine. The 828-MK3 has both midi and audio inputs & outputs (including ADAT inputs/outputs).
Other people will, no doubt, suggest audio devices from other companies. All probably get the job done well. But if you're thinking about recording a lot of instruments at the same time, it is my understanding that it is best to avoid USB-based devices.
Good luck with your search and your decision.

How to get rid of the attention to choose between my wifi network or the apple tv? That appears in the screen saver

When the screen saver is on appears an message where ask me to choose between my wi fi network or my Apple Tv in order to get the signal from my PC. There is something I must do to set up the Airplay, if so, what I have to do and where?

If you are talking about the header bar of the Message Pane the only way to get rid of it completely is to close the message pane by pressing F8.
There is a add on called Compact Header that will let you make it smaller.
