Can a session EJB be accessed by more than one client?

Hello,
I would like to have an instance of a persistent EJB which is accessible by more than one client and which will not be destroyed after usage. Apparently session beans can only be accessed by one client and are created every time they are accessed. In my case this creation is quite time and resource consuming. Is it an alternative to use an entity bean instead, even if the logic of the bean doesn't have anything to do with direct database access?
Thanks.

It seems to me that what you want is exactly a session bean will do. The EJB container is responsible to maintain a certain number instances (configurable) of your session bean and serve multiple clients at the same time. Session beans are not necessarily destroyed after serving a client. If you configure your ejb server to have a pool size of 2 to 100, then you will always have at least 2 instances (no more than 100 even there are a lot of client access) of this ejb ready to serve. The only thing not clear to me is that do you want to use only ONE instance of this bean or you don't care as long as multiple clients can access this bean's service? Since you mentioned that there is not a real database access, you can certainly use a Singleton but a 'regular' session bean with static fields should do it also if these fields will not be modified by clients.

How can a file be accessed by more than one app?

Hi,
I am new to iOS4 and the whole iPhone, iPod technology. I am really a windows user.
How can a file be accessed by more than one app. In my case I want to transfer a midi file from my PC to my iPod Touch and be able to open it from a couple of Midi Players which I am evaluating - or does each Midi Player have to import the file seperately for its own use?
Thanks,
Sam

Can we use same program ID for more than one RFC scenarios

Hi experts,
            I am working on a RFC to FILE scenario. I have created one TCP/IP connection in SM59 with a program ID. Can we use this program ID for more than one scenario. I have written code as below
data: iquote type standard table of ZIQMD initial size 0,
      IPRODUCT type standard table of ZPMS initial size 0,
      wa_quote type ZIQMD,
      wa_PRODUCT type ZPMS.
CALL FUNCTION 'Z_CBT_RFC_QUOTEMASTER'
TABLES
    I_QUOTE       = iquote          .
CALL FUNCTION 'Z_CBT_RFC_QUOTEMASTER' in background task DESTINATION
'ID4'
TABLES
    I_QUOTE       = iquote          .
COMMIT WORK.
CALL FUNCTION 'Z_CBT_RFC_PRODUCTMASTER'
TABLES
    IPRODUCT       = IPRODUCT          .
CALL FUNCTION 'Z_CBT_RFC_PRODUCTMASTER' in background task DESTINATION
'ID4'
TABLES
    IPRODUCT       = IPRODUCT          .
    COMMIT WORK.
when i am executing the code like this. i am able to send the data to 'Z_CBT_RFC_QUOTEMASTER' , but iam not getting data for 'Z_CBT_RFC_PRODUCTMASTER' interface. ID4 is the connection that i have created in SM59. with program ID as ABCD.
              Can i use the same connection for all interfaces.Please help in this, if we can use same connection for all interfaces. then how to make changes in XI.
Thanks in advance.
Thanks & Regards,
Poorna.

Just tried this and I can confirm that my earlier understanding was correct!
One of my colleagues confused me out and the conclusion is,
1. You need a separate TCP IP Connection for every interface with a Unique program ID.

Hi, China6450.
Thank you for visiting Apple Support Communities.
I would recommend setting up Manually manage music. This will only allow music to be synced from the computer to the iPod nano. Here are some helpful articles that will walk you through the process.

You can make a copy of an existing song, then change the album, artwork and track number details. You cannot make the same physical file show up in two different albums.

Just bot a macbook pro to replace one of my pc's. can't figure out how to have more than one website open at a time like explorer. Is it possible to do?

I can't figure out how to open more than one website at a time like explorer does on a pc. would like to know if it Is possible or not.

Tabbed browsing is the way. Go to Safari's View menu:
and click "Show Tab Bar." When you see a link on another site you wish to open without closing the first site, simply right-click and select "Open Link in New Tab."

Can I install Adobe Creative Cloud in more than one computer with the individual plan?

I don´t have clear about the diference between individual plan an teams. My questions are:
Can I install Adobe Creative Cloud in more than one computer with the individual plan?
The team plan means that I have to pay for US$70 for each computer that i want to install the creative cloud even if I am the only user?

Hi heymarusia,
Yes, you can install and activate Creative Cloud desktop applications on two computers, regardless of operating system, for the individual associated with the Creative Cloud membership. See the product license agreements page for more information.

Can I simultaneously configure a device to more than one task?

Can I simultaneously configure a device to more than one task? I am trying to trigger on some of the input data. When I tried to configure the same device to more than one task, I get an error:
Error -10408 occurred at Digital Group Config.
Possible reasons:
NI-DAQ LV: The specified channel is in use.
I have attached a copy of my VI. In the first and second sequences I am using device 1.
Attachments:
Can_I_simultaneously_configure_a_device.doc ‏19 KB

Hello;
The best way to have multiple tasks running on the same DAQ device is by syncronizing those in the hardware level. What I mean by that is, to use the same clock pulse train to clock the different tasks.
For instance, in case you want to do Analog Input and Analo Output at the same time, you can use the AI Start Scan (which is the clock pulse train that will clock the analog input task) to be routed to the AO Update clock (which is the clock that controls the Analog Output tasks of your device). You can extend that idea for counter operations as well.
For digital operations, if you are not using one of the digital boards that support strobed operations, such as the 653x ones, you won't be able to synchronize the digital tasks with the analg tasks, s
ince the digital ports updates through Software calls only.
You are probably getting that error because you are trying to use the Digital Group Config.vi (or some other VI that calls the Digital Config.vi) with a board that doesn't support handshaking operations, such as the MIO ones.
Hope this helps.

Can we delegate a business object to more than one Subtypes?
So unless we delegate that Sub type , will the new method of that sub type be not called from our WF?

Can a personnel area be assigned to more than one company code?

Hi experts,
Can a personnel area be assigned to more than one company code?
Regards,
Anita George

Yes, as Siva said it is not possible.
Between personnel area and company code -
many to one mapping is allowed but one to many is not allowed. That is you can map more than one PA to 1 company code but 1 PA can not be map to more than one company code.

Can't SSAS engines make use of more than one aggregation to answer a query?!

I have a very simple cube (just for testing and training) . This cube contains two dimensions: [Dim Soccer Player] contains one attribute hierarchy [player name], the other dimension
is [Dim Match Acts] contains also one attribute [Acts] which has values like fouls, goals, saves, tackles… etc. And of course a Fact that contains one measure of Just Count ... that simple ... so this cube can
answers a question like how many goals scored by "Messi", for example ... a very simple trivial cube.
I'm testing aggregations and their effect. so first I've designed one aggregation (Aggregation 0) on the granularity level of [Player name], then
I run a query to get the count of ALL the[Acts] done by each [Player name] ... I've checked the SQL Profiler and I found that the aggregation was used.
Then I cleared the cache, and I run another query, but this time to get just the number of Fouls committed by each [Player name], I checked the Profiler but the Aggregation 0 was NOT used.
I went back to the aggregations design tab in BIDS, and I added another new aggregation (Aggregation 1) on the level of [Acts], so now I have two aggregation one on the granularity level of
[Player name] and the second on the level of the [Acts].... I cleared the cache again and rerun the last query. NONE of the aggregation was used!
In the third test I deleted Aggregation 1 and added [Acts] to Aggregation 0. so Aggregation 0 now on both [Player name] AND [Acts]... cleared the cache and rerun the last query. Aggregation
0 appeared again.
I just want to make sure (and if possible know why) the SSAS engine can't make use of and combine more than one aggregation to serve a query (point number 2), and that to design an aggregation
that will serve a query which contains attributes from different dimensions, I have to add ALL the attributes in that query in that one aggregation, like point 3 ... is this true?!

I think you are on the right track. You need to include all the attributes used in one query in the same aggregation (like #3) for it to be used. Example #2 works as I would expect. Queries above the grain of the agg (query by player name and an agg by
player/act can be used) can be used. Queries below grain of the agg (example #2) can't use the agg.
