What are the performance tradeoffs when using more than one EntityStore?

Hi,
I have different accounts where each account has the same set of Entity classes. I don't know yet wheter to have one EntityStore for each account or have one EntityStore for all accounts together and do a lot of 'joining' when retrieving Entities.
This is a very similar use case as with the FAQ http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#37 . The only difference is that I want to use DTP.
It would be great if you could answer me the following questions:
1.) Do basicly the same answers as in the FAQ apply to EntityStores?
2.) How expensive is an EntityStore (memory, speed - creating and releasing)?
3.) What would you recommend? I have to do a lot of secondary-index lookups which are restricted to one account. There are about 10 Entity classes and about 1000 accounts.
Thanks,
Christian

Hello,
It would be great if you could answer me the
following questions:
1.) Do basicly the same answers as in the FAQ apply
to EntityStores?Yes, they apply.
2.) How expensive is an EntityStore (memory, speed -
creating and releasing)?For each store, there is an underlying Database per entity class and per secondary key. And for each store there is a catalog database which is also kept in memory.
3.) What would you recommend? I have to do a lot of
secondary-index lookups which are restricted to one
account. There are about 10 Entity classes and about
1000 accounts. I recommend using a single store for best performance and resource utilization.

Why does iPhoto (9.0/11) not retain the Event name when exporting more than one event? (using File - Export - Album name with number).

Why does iPhoto (9.0/11) not retain the Event name when exporting more than one event? (using File -> Export -> Album name with number).
Exporting a single Event retains the Event name which is what I'd expect. But highlighting more than one event and exporting it renames the images to Events 001.JPG, Event 002.JPG etc.
I was recently on holidays and had all my events nicely split on Dad's computer but when I went to export it I couldn't retain any of this information. Now I have to replicate this all again on my computer.
It wasn't possible to export the entire library as the external drive was fat32 format an I didn't want all of it. It would be nice to export a bunch of events to someone and have it retain the name.
Does anyone have a work around or will this be fixed at some point by Apple?

When using more than one tab, once I have opened a pdf using firefox my laptop will not allow me to type or click in another tab unless I drag the pdf into it's own window?

when using more than one tab, once I have opened a .pdf using firefox my laptop will not allow me to type or click in another tab unless I drag the .pdf into it's own window? not a major problem just irritating.

I found the cause but no solution, it's actually a plugin that does that: divx plus weblpayer (it gets installed when you install DivX on your system), if you disable it and restart firefox it all works again. But I want that plugin... so DivX need to fix this, unless it is a Firefox bug in its own core... anyway these two together creates the problem.
(I'm running Firefox 9.x on OSX Lion)
I also wish firefox tab tear out tab worked more like chrome's tab tear out, much friendlier...

Rendering Error when using more than one DataSheetView on a Enterprise Wiki-Page

Hi Experts,
how to reproduce:
Add two Custom Lists with some Fields (Add Lookup-Columns to both Lists).
Add a DataSheetView to each List and mark it as Default-View
Create a Enterprise Wiki-Page
Add a WebPart (Custom-List-1)
You will see the Content from List 1 as DataSheet-View (because it is the Default-View)
Add another WebPart below the previous added WebPart (Custom-List-2)
You will see the Content from List 2 as DataSheet-View (because it is the Default-View)
Notice that the First DataSheet has faulty Rendering. The Lookup-Columns having more than one 'Arror-Down' Image and it is even on the left. If you click into different Column, different row you get the same.
I can reproduce this behaviour anytime.
Environment: SharePoint 2013 Enterprise, IE10
If you use Development-Tools to identify first datarow of first DataSheet you can see that it has to do something with the related <Input>-Tags:
<div class="combobox-placeholder" id="jsgrid_combobox" style="left: 27px; top: 32px; width: 117px; height: 29px; border-top-color: currentColor; border-right-color: currentColor; border-bottom-color: currentColor; border-left-color:
currentColor; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-top-style: none; border-right-style: none; border-bottom-style: none; border-left-style: none; visibility: inherit; ; direction: ltr; min-width:
117px; background-color: transparent;">
<input class="cb-textbox " style="width: 156px; height: 25px;" dir="ltr" type="text"/><input tabindex="-1" title="Dropdown" class="combobox-img" style="height: 29px;"
dir="ltr" type="button" value="▼"/><input class="cb-textbox " style="width: 84px; height: 25px;" dir="ltr" type="text"/><input tabindex="-1" title="Dropdown"
class="combobox-img" style="height: 29px;" dir="ltr" type="button" value="▼"/>
Please have a look into it. Current Workaround for me is to have a Default-ListView in first WebPart. But then Customer has to click the Edit-Button to Change the Item in the releated EditForm. This is a Show-Stopper here!
With Best Regards,
Ronny

Hi Ronny,
According to your description, the lookup column would render incorrectly when adding more than one datasheet view in the Enterprise Wiki page.
I tested the same scenario per your post, and I got the same results as you got.
We will help to submit the issue to proper pipeline for you.
Again, thank you for your report which will definitely make SharePoint a better products. There might be some time delay.
Appreciate your time and patience.
Best regards.

How to show all data when using more than one parameter?

Hi All,
I used a query like this to show the data in a report:
select col1, col2 // col1 and col2 are columns of tabale tab1
from tab1
where
tab1.col1 =
(case when :P_COL1 IS NOT NULL then // :P_COL1 IS A USER PARAMETER TO EQUAL COL1
:P_COL1 ELSE tab1.col1
end)
AND TAB1.COL3 =
(case when :P_COL3 IS NOT NULL then // :P_COL3 IS A USER PARAMETER TO EQUAL COL3
:P_COL3 ELSE tab1.col3
end)
The problem is when I run the report with paramters values or not, It shows the data which is not null for both col1 and col3.
That is when the value of col1 or col3 is null the report would not return that record!
I want the report to show all data not only values which is not null!
How to do this?

Rainer,
That where clause will fail when col1 in the table is null and the parameter has the dummy value. Consider the following:
variable p_col1 varchar2
exec :p_col1 := 'yourdummyvalue';
select
from
     select 'yourdummyvalue' col1 from dual
     union all
     select 'other' from dual
     union all
     select null from dual
     union all
     select 'X' from dual
) tab1
where nvl(tab1.col1,'yourdummyvalue') = nvl(nvl(:p_col1,tab1.col1),'yourdummyvalue')In this case, the query returns the row with null and the row with 'yourdummyvalue', where only the row with 'yourdummyvalue' should be returned.
You must do something like this:
where ( :p_col1 is null or ( :p_col1 = tab1.col1 ) )That one is the simplest and does not need a dummy value. Here are some other more complicated examples:
where nvl( :p_col1, 'yourdummyvalue' ) = decode( :p_col1, null, 'yourdummyvalue', tab1.col1 )or this:
where nvl( :p_col1, 'yourdummyvalue' ) = nvl2( :p_col1, tab1.col1, 'yourdummyvalue' )In the last 2 cases, it will not matter if the dummy value exists in the data, but they are unnecessarily complex.

EJB3 CORRUPTED when using more than one PersistenceUnit

Hi,
I am using JSF, EJB3 on Glassfish. CMP and JTA.
This is the scenario:
A user logs into application choosing one Persistence Unit (like in JavaSE). This is only at the beginig as I want to use Glassfish CMP and JTA.
    public EntityManagerFactory getEmf() throws Exception {
        configOverrides = new HashMap<String,Object>();
        configOverrides.put(TARGET_DATABASE,TargetDatabase.SQLServer);
        configOverrides.put(TARGET_SERVER,TargetServer.SunAS9);
        configOverrides.put(JTA_DATASOURCE,"jdbc/"+puName);
        configOverrides.put(SESSION_NAME,puName+"_session");
        emf = Persistence.createEntityManagerFactory(puName,configOverrides);
        return emf;
    }I then put the corresponding PersistenceUnit name in http Session scope to be used later on.
I created a CommonEjbImpl to further inject via Jndi (and therefore use CMP and JTA) an EntityManger in each EJB3 as follows:
@PersistenceContexts({
   @PersistenceContext(name="pu/SOCIETE1", unitName="SOCIETE1"),
   @PersistenceContext(name="pu/SOCIETE2", unitName="SOCIETE2"),
   @PersistenceContext(name="pu/SOCIETE3", unitName="SOCIETE3"),
   @PersistenceContext(name="pu/SOCIETE4", unitName="SOCIETE4"),
   @PersistenceContext(name="pu/SOCIETE5", unitName="SOCIETE5"),
   @PersistenceContext(name="pu/GENESYS_EXEMPLE", unitName="GENESYS_EXEMPLE")
public class CommonEjbImpl {
    public EntityManager initEm() {
        LogUtil.log(this.getClass(),(String)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("database"));
        return initEm((String)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("database"));
    public EntityManager initEm(String puName) {
        EntityManager em = null;
        try {
            em = (EntityManager) new InitialContext().lookup("java:comp/env/pu/"+puName);
        } catch (NamingException ex) {
            LogUtil.error(this.getClass(),ex);
        return em;
    public void cleanup(EntityManager em) {
        //LogUtil.log(this.getClass(), "CLEANING EJB..with em: "+em);
        if (em != null && em.isOpen()) {
            em.close();
    } And in each EJB3, I use this CommonEjBImpl to get the Entity Manager like this:
@Stateless
public class TreeEJB extends CommonEjbImpl implements TreeEJBLocal {
    public TreeEJB() {
    private EntityManager em;
    @PostConstruct
    public void init() {
        em = super.initEm();
    @PreDestroy
    public void cleanup() {
        super.cleanup(em);
}I have also a JSF backing bean (in SESSION SCOPE) "TreeBean" in which i Inject an EJB3 like this:
    <managed-bean>
        <managed-bean-name>TreeBean</managed-bean-name>
        <managed-bean-class>com.mfpsoft.bean.tree.TreeBean</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
    </managed-bean>and:
public class TreeBean extends BeanLoader {
    public TreeBean() {
    @EJB
    private TreeEJBLocal treeEJB;
    @PostConstruct
    public void init() {
        treeEJB.init();
}SO, imagine what is happening:
USER1 logs (a persistence unit)
USER2 logs (a different persistence unit)
USER1 refresh tree for example
USER2 rehresh tree also
==> USER2 GETS data from USER1 persitence unit
My questions:
EJB3 refrence seems to in application scope. Is thereonly one EJB3 refrence per appication?
If so, how can I use same EJB with different persistence COntexts at the same time.
Would this be a workaround ?? get entityManager at each business method of the EJB like this
    public Object Method(Object object) throws Exception {
        EntityManager em = super.initEm();
        try {
            ...//em operations
        } catch (Exception ex) {
        } finally {
           em.close();
    }Would the data be corrupted if simultaneous access to same method by diffrent users?
This issue is quite URGENT
I would really appreciate a quick help on this
Many thanks in advance

Hi Zsom,
Thanks for your answer
Let me explain more clearly.
My architecture is as follows: using JSF, Glassfish and ...SQL Server!! (! i know but this is mandatory requirement as our application is full web version of an existing ERP application already sold and installed by more than 1000 of our customers...
I am using
JSF-->JSF Managed Bean (Session for some and Request for almost all when logged )-->EJB Interface-->EJB Impl-->Entity-->Database
Our application is ERP that our customers uses to managed several companies simultanously .
This product ,mainly for intranets, is delivered with glassfish, the web application and SQL server containing by default 5 databases SOCIETE1,...SOCIETE5...but more can be created by our consultants for this customer....
All databases have the same schema but not the same data.
Sincerely, if I had done the desgin of the database, for sure I would have put all SOCIETEn in one DB but this is historical and I cant do anything against it.
You have to see in our case, a database as a company of our customer (a joint venture for instance), each of which with particular configuration, customers, orders, invoices, contacts....
I have a persistence Unit (using JTA and CMP) per database , each using a connection pool managed by Glassfish.
At the login of my application, the user (a user of our cutomer that bought this product), choose a database (a company actually lets say SOCIETE1), ...enter logging info and connect.
The user must also be able to launch another browser window and connect lets say to SOCIETE2, and then work on SOCIETE1 AND SOCIETE2 simultanously.
Also, I need Session Scope as there is configuration data that I need to keep over all pages. This configuration data is depending on the database connected to and the user.
A session is therefore linked to the pair USER+DATABASE
When selecting the database (company) for combo in logging form, the only way I found is fisrt to check if database(company) exists and can be connect to using at first begining Persistence.CreateEntityMangerFactory.. (i know that this is not J2EE and CMP but merly used in Java SE environments..).
This step is only used for checking database.
Then, if creation did not generate a Persistence Exception , I can use CMP and an EnityManger in EJB by JNDI lookup (as DI is not possible because you need constant in unitName);
Doing so, the EJB (which only handles actions on Entities) manage the entities of the corresponding company SOCIETE1 or SOCIETE2, or.....
I know that I might use antipatterns here, but actually this is the only solution I found
Would an extra Layer between JSF bean and EJB do the trick....if yes how to inject the good persistence unit in my EJB is still in question.
More if one Persistence unit is injected (assuming EJB being stateless) and another user working on another persistence unit is using the same EJB, then I go back in my first message on this topic
As the number of databases for a customer is unknown, I can not create an EJB par database (lets says EJB_SOCIETE1, EJB_SOCIETE2,...). I agree that in this case they would be stateless....
Do you have any suggestion to repect patterns in this situation.
This would be greatly appreciated
Thanks again
Nicolas

NIO - Selector problem - when using more than one in same application

Hi,
I'm developing a multiplayer-server, which shall be able to handle at least 2000 concurrent clients. To avoid the use of 4000 threads for 2000 clients (a thread for each stream), I would like to use NIO.
Problem:
The server has of course a ServerSocketChannel registered with a Selector, and when clients connects, the SocketChannel's is received. IF these channels is registered (OP_READ) with the same Selector-instance as the ServerSocketChannel, there is no problem and the Selector recognizes when a registered SocketChannel is ready for OP_READ - BUT when the received SocketChannels is registered with another Selector-instance than the one the ServerSocketChannel is registered with, the Selector NEVER recognizes, when a SocketChannel is ready for OP_READ - why not and how do I solve the problem? Only one thread can service the same Selector-instance, and when both receiving many connections and read/write, this could easily be a bottleneck
Following is the used code; 2 classes: ClientListener (has a ServerSocketChannel registered with a Selector) and ClientHandler (has another Selector where the SocketChannels is registered and a thread-pool that services all the SocketChannels, when they are ready for read/write):
public class ClientListener {
private static final int BACKLOG = 32;
private int port;
private Thread internalThread;
private volatile boolean noStopRequested;
private ServerSocketChannel ssc;
private static Selector selector;
private ClientHandler clientHandler;

      if (bindAddress.equals(""))
        inetAddress = InetAddress.getLocalHost();
      else
        inetAddress = InetAddress.getByName(bindAddress);
      ssc = ServerSocketChannel.open();
      ssc.socket().bind(new InetSocketAddress(inetAddress, port), BACKLOG);
      ssc.configureBlocking(false);
      Runnable r = new Runnable() {
        public void run() {

    Client client = new Client(...);
    SelectionKey key = sc.register(selector, SelectionKey.OP_READ, client);
    key.selector().wakeup();
public void stop() {
}

Ok, found the solution here: http://forum.java.sun.com/thread.jsp?forum=31&thread=282069
"The select() method holds a lock on the selector that
the register() method wants to acquire. The register()
method cannot continue until the lock is relased and
the select() method will not release it until some key
is triggered. If this is the first key you're adding
then select has nothing that will wake it up, ever.
The result is, obviously, a deadlock.
The solution is to have a queue of pending connections.
You put your new connection in that queue. Then you
wake up the selector and let that thread go through
the queue, registering connections."

What are the correct setting when using a canon t4i in sequence ?

im new to adobe premiere and i've been using sony vegas. If you can help me please comment. Thank you

If you are on the trial version (assuming this is CC7) drag a clip from the Project window into the New Item Icon (lower right bottom of the window)
That will give you a matching sequence for your clips.

How can I use more than one Data Provider in my web Apps

I am trying to use two different data provider in my web apps to run two different queries from the same table ,the data provider A is working correctly but when I attempt to run data provider B ,It display an error page ,here is the error message : Exception Details :javax.servlet.ServletEx ception

Hi,
You can use more than one data provider in your application. However if you have defined a dataprovider for a particular table already, and wish to bind a component, select the component and use its context menu to Bind to Data...

What are the major risks buying used lenses ?

i just bought my first dslr, and i was wondering what are the major risks buying used lenses ?

You need to be able to inspect and test the lens.
Look for obvious signs of physical damage, drops, etc. (cracks, dents, etc.) A lens normally will get some signs of wear but as it's a used lens, you expect *some* wear... you're really looking for signs of damage.
Remove both front and rear caps. Look through the lens into a bright no-contrast background (a white wall, a blue sky, etc.) and check the optics. You're looking for signs of mold growth or damage to coatings. Minor dust on internal optics wont impact the lens performance... so while you wouldn't want major amounts of dirt... don't worry too much about minor bits of dust (I've actually helped prove this to someone by clipping a 3M PostIt note down to a tiny 1/4" x 1/4" size and sticking it on the front glass. Take a photo... nothing shows in the photo (even a piece of "dirt" that big wont show because the camera cannot focus on anything that close to the lens.)
Rotate the focus ring from end to end. You should feel a smooth and consistent amount of friction as you rotate the focus ring. There should be no rough spots. Listen to the lens as you do this... there should be no grinding noises.
Do the same with the zoom ring but in addition to checking for smooth consistent performance (no sticky or rough spots) you're also checking to make sure nothing seems excessively worn (nothing wobbles loose... very heavily used lenses can do that after enough wear.)
Connect the lens to the camera and make sure the camera can completely operate the auto-focus motors without a problem and/or if it's an image stabilized lens that the IS components are working.
Set the camera to max aperture (e.g. f/22, f/32.. depending on the lens) and press your camera's "depth of field preview" button (if you don't know which button is your DOF preview, check your manual. Canon tends to move that one around a bit but it's almost always on the front side of the camera near the lens mount.) You want to press and release it a few times. This will cause the lens aperture blades to stop down to the aperture you set. Release... do this while watching the lens. You should see the aperture blades move in and out (well... they snap in and out very quickly). You want to make sure it works ok, the camera gets no error codes, and there's no signs that anything is sticking.
And then there is the focus test...
Focus the camera preferably at a FLAT surface that has lots of detail.... such as the brick wall of a building. Make sure the camera is level and that the camera's focal plane is parallel to the plane of the wall. Take a test photo at low f-stop and inspect. You're checking to verify that the focus works and that the focus is reasonable across the image. As you inspect from left ot right and top to bottom you are looking to make sure the focus is more or less equal (if the right side of the image is focused... but the left side of the image is soft... it would indicate that lens elements are skewed (lens isn't collimated). It's difficult for a lens to get into this situation unless it was dropped and you'd probably see signs of damage.

Compare the strengths and limitations of the Web Parts
It’s important that you understand the strengths and limitations of the two Web Parts because if you choose the wrong one, your site could run into performance problems. You can use both Web Parts to show content that is based on a query. In a simplified
world, here’s how you can decide between the two:
Use the CQWP when you have a limited amount of content, your query is simple, and you don’t expect your content to grow much in the future.
Use the CSWP in all other scenarios when you want to show content that is based on a query.
The table below gives a comparison of the two Web Parts:

Hi mate,
You need to make your question clearer. Tell us what your requirements are and we can help you more.
Some hints:
You can read data from InfoProviders (e.g. InfoCubes, DSOs etc) using function module RSDRI_INFOPROV_READ.
Hope this helps.

I use more than one computer to access my four business email accounts. When one computer is on (and mail is open) emails do not get through to the other computers. This is fine, but how do I make one of the other computers the dominant one?

I use more than one computer to access my four business email accounts. When one computer is on (and mail is open) emails do not get through to the other computers. This is fine, but how do I make one of the other computers the dominant one?

I assume these are POP accounts and all computers are set to remove from Server after downloading.
So on the non dominant ones... Mail Preferences>Accounts, highlight an account, Advanced tab, uncheck remove from Server, just have the main dominant one remove from server.
Or get/setup IMAP accounts.

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

From a practical perspective, besides the 64 bit version being a bit faster at just about everything, limitations on document size are lifted in the 64 bit version. Essentially, how much can do is limited only by how much RAM you have installed in your system. You can do things like have larger documents, deeper history, etc. and have it all work quickly.
On the other hand, many 3rd party plug-ins, especially older ones, only provide 32 bit versions, which will only run in 32 bit Photoshop.
Both 32 and 64 bit versions are installed by default. It's important to note that most of the preferences are separate between the two, so you can have two slightly different setups that might help with specialty operations you might need. This gets pretty subtle, but for example I keep the 32 bit version configured with only 1 cache level, so all previews of high bit depth images are always composited in high bit depth. This aids me with some aspects of astroimage processing. It's slower, but more accurate. By contrast I have more cache levels configured for my 64 bit version, so that's faster for general photography work.
