Should i use discriminator in InheritanceType.JOINED?

There are three InheritanceType, when i use InheritanceType.JOINED, should i define discriminator just like InheritanceType.SINGLETABLE?
I dont think i need discriminator anymore, but i saw books about EJB3, the examples use it.
Should i use discriminator in InheritanceType.JOINED?

Extended vs joined network - which should I use

I have a Time Capsule connected to my iMac and in the living room I have an airport express that I stream music to. Which should I use. Extended or joined netowrk. I find that if it is extended my MacBook Air, iPad and iPhone run a lot slower than if it is a joined network. If it is an extended network all my portable devices are sitting on the Airport Express. If it is a joined network they are sitting on the time capsule where I get the better performance.
In terms of the streaming of my music though it doesn't matter whether it's joined or extended.

I have a Time Capsule connected to my iMac and in the living room I have an airport express that I stream music to. Which should I use. Extended or joined netowrk.
For the purpose of streaming only, you will want to configure the AirPort Express to "join" the wireless network provided by the Time Capsule. The Express will, in turn, perform simply as another wireless client on the network and not introduce the bandwidth overhead of an extended network.

That is correct.

Joining a OD, wich account should I use?

Hi all,
This is my first post here since I'm quite new with Mac OS X Server.
I've set up my new Mac mini Server as OD Master, and I have created 2 OD accounts (oduser1 & oduser2).
Now, I go to my new iMac :-P and from my iMac local admin account (localadmin), I would like to join my OD. I go to Login Options and add my OD server, and I get 2 options:
- Join Only: As I don't want my local admin user to be managed, I believe this is the best choice.
- Set up services: If I don't choose this option now, will these services going to be configured for my network users (oduser1 & oduser2) next time they log in?
One more question, when joining to OD server, it asks you to insert user&password, which OD user credentials should I use? oduser1 or oduser2, or should user diradmin? (remember I don't want localadmin to be managed)
Thank you all!!!

Hi I come back with my new username since a forum update.
I find I have been well received, as -I ask for a Sun software and I am anwered with Dark Basic, and I ask clearly in my second post how to develop on mobile phones, and have been answered "You don't have the "right" to +complete+ initial post since you didn't tell everything in initial post.
You. How are you receiving new developers. Do you really want to help users know how to use Oracle products, or do you want to make it as obscure as possible and chock.
Now I precise, I was -when it was at an enhancement and growing people using it- how to have an editor -visual editor with drag'n drop facilities AND/OR a IDE, to publish on mobile phones using JAVA.
I don't aim anymore to publish on phones since each new OS has its XNA, Apple or Chrome development tools, but I am amazed how user-friendly and respectful and full of kindness I have been recieved by 2 or 3 pople from the community. Is this forum moderated and can a moderator or administrator or a professional answer me? -> the question is in the title: Which software(s) should I use to create a game? I'm looking up evidently to Oracle-only downloadable products.

[JPA] How to avoid excessive joins in queries on InheritanceType.JOINED

Hi,
Let me use an over-simplified example to illustrate my question:
Let's assume I have two classes: SuperClass and SubClass. As the name suggests, SubClass extends SuperClass.
I have mapped them in JPA via:
@Inheritance(strategy=InheritanceType.JOINED)
@DiscriminatorColumn(name="CTYPE", discriminatorType=DiscriminatorType.INTEGER)
@PrimaryKeyJoinColumn(name="ID")And now let's suppose I run the following query:
Query q = entityManager.createQuery("select o.id from SubClass o");In this case, TopLink Essentials generates SQL with a join between the base table and the detail table. Why? All I need is the ID which is available in the detail table too. The base table doesn't need to be included in the query.
Is there a way to avoid the unnecessary join? I even tried mapping the ID column in both entities but it didn't help.
Best regards,
Bisser

Thank you for you reply, Doug!
I don't want to instantiate SubClass. I only wish to get the ID. I don't need validations or fields from the superclass.
Should I resort to using native SQL for that?
(By the way, the real query that I use in my program instantiates a completely different entity. I use the SubClass in a subquery. And I don't need the SuperClass to get involved. I have a foreign key that guarantees that the SuperClass's row exists in the database.)
Best regards,
Bisser

Hi,
Thank you for the prompt reply, what I would like the query to generate is the master data GL listing for GL account,GL description,Tax category, posting without tax allowed column where i use BRF as the data source for logical database to generate the quick viewver but the BRF data source do not have the GL description.
How I can join table/join query or what are the data source should i use so that i can able to generate the query with GL master data listing by company code by display GL account,GL description,Tax category, posting without tax allowed?
Between,do you have any reference/link/document on the how to use the SQV1?
Also, what the difference between SQV1 and SQ01 ?
And also what are the sap query,inforset query,quick viewer mean for and what are the difference between them also when should i use sap query,inforset query,quick viewer to generate the query?
Please help.

How to prevent Oracle from using an index when joining two tables ...

How to prevent Oracle from using an index when joining two tables to get an inline view which is used in an update statement?
O.K. I think I have to explain what I mean:
When joining two tables which have many entries sometimes it es better not to use an index on the column used as join criteria.
I have two tables: table A and table B.
Table A has 4.000.000 entries and table B has 700.000 entries.
I have a join of both tables with a numeric column as join criteria.
There is an index on this column in table A.
So I instead of
where (A.col = B.col)I want to use
where (A.col+0 = B.col)in order to prevent Oracle from using the index.
When I use the join in a select statement it works.
But when I use the join as inline view in an update statement I get the error ORA-01779.
When I remove the "+0" the update statement works. (The column col is unique in table B).
Any ideas why this happens?
Thank you very much in advance for any help.
Regards Hartmut

I think you should post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your query resp. update statement. Please use the \[code\] and \[code\] tags to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Usually if you're using the CBO (cost based optimizer) and have reasonable statistics gathered on the database objects used the optimizer should be able to determine if it is better to use the existing index or not.
Things look different if you don't have statistics, you have outdated/wrong statistics or deliberately still use the RBO (rule based optimizer). In this case you would have to use other means to prevent the index usage, the most obvious would be the already mentioned NO_INDEX or FULL hint.
But I strongly recommend to check in first place why the optimizer apparently seems to choose an inappropriate index access path.

Should both indexes be bitmap when joining or neither?

I have a table with several hundred K rows (expected to be in the millions in a matter of months, estimated 200M in a few years) with one particular smallint column that's an FK to a reference table. In the reference table it's the PK and there are only about 500 values and it is expected to grow very slowly, if at all. The large table is loaded daily in a batch process after which a stats refresh can be issued, so updates while users query is not a concern.
Am I correct in assuming the ratio of 500 to million+ makes a good low cardinality candidate for a bitmap index? The goal is equal between saving space and improving performance. Most queries join the reference table because a very small subset (or just one) of the possible values in the reference table are needed, not all of them.
If the index's purpose is to support joining to the reference table, does the PK index on the ref table need to also be bitmap type to make the most of the bitmap structure?
Thanks for any help!

Your use case would not be appropriate for a bitmap index.
Bitmap indexes provide benefits when used in combination with other bitmap indexes on the same table. For those use cases Oraclel can manipulate the bitmap indexes against either other ((A AND B) OR (C AND D)) very efficiently to identify the rows of interest.
You should not create either of the join indexes as a bitmap index.
See the Data Warehousing Guide for information on bitmap indexes and how/when to use them
http://docs.oracle.com/cd/B28359_01/server.111/b28313/indexes.htm
>
Bitmap indexes are most effective for queries that contain multiple conditions in the WHERE clause. Rows that satisfy some, but not all, conditions are filtered out before the table itself is accessed. This improves response time, often dramatically. If you are unsure of which indexes to create, the SQL Access Advisor can generate recommendations on what to create. As the bitmaps from bitmap indexes can be combined quickly, it is usually best to use single-column bitmap indexes.

ESB vs BPEL : which one should we use

Hello All-
We need some pointers regarding the strength and weaknesses of ESB and BPEL and in which scenarios we should be using either ESB or BPEL or both.
Currently, our EDI processing system is on BPEL 10.1.2.0.2 version and the details are given below:
BPEL 10.1.2.0.2 and Oracle Integration B2B 10.1.2
BPEL is used for transformation and feeding the messages to B2B. It's also used for transaction tracking, error handling and notification. We have implemented both inbound as well as outbound EDI.
File, DB and AQ adapters are heavily used but we have seen severe performance issues under load
As part of upgrade to 10.1.3 version we are evaluating whether we can use combination of ESB (using the file adapter) and BPEL(for transformation, transaction tracking, error handling and notification) and whether it is recommended. Basically we are evaluating the option of migrating the processes to 10.1.3 version as -is or introduce ESB to reduce performance bottlenecks.
Please provide us pointers to recommneded best practices as well as any documents/case studies.
Please get back to me if you need any additional information.
Thanks in advance.
Regards,
Dibya

Hi Dibya,
Oracle BPEL can be used for integration code but its not designed/optimised for it.. Oracle BPEL is a Business Process Execution Language and as such its optimised for managing and coding business processes, whereas an ESB is quite simply a highly efficient intergration product. Its principle objective is to join two different services together quickly, efficiently and bi-directional.
Specifically an ESB moves data via
Connects services via different adaptors (WebServices, FTP,File,JDBC etc) and protocols (HTTP,JMS)
Enriches and transform data using XSL & domain value mapping lookups
Routes messages based on data in the message payload and/or header
and finally and often overlooked feature is that an ESB
Virtualises services, quite simply adds a facade layer to your infrastructure...
Its also worth noting that doing integration work with Oracle ESB is not only quicker to "build" but its also quicker in its execution. I've been told by some collegues in the US that an integration process in ESB product is approx twice the speed of same process in Oracle BPEL..
So to recap
Use ESB when
You want a really low cost solution
Only need connectivity, simple transformations and routing
Use BPEL+ESB when
You need to code complex business logic
Integration with Workflow
Complex transforms potentially involving the database
Have Long running processes which may or may not be stateful.

EJB 3.0 InheritanceType JOINED stategy problem

hi all,
i have 3 table into database
Root Table : PAYMENT_METHOD_DATA
Child Table : BANK_TRNSF_METHOD_INFO
Child Table : SCRATCH_METHOD_INFO
in java i have inheritance joined strategy, then root class loojks like this :
@Entity()
@Table(name = "PAYMENT_METHOD_DATA", schema = "CCARE")
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "METHOD_DATA_TYPE", discriminatorType = DiscriminatorType.STRING)
@DiscriminatorValue("Base_MethodData")
public abstract class PaymentMethodData implements Serializable {
}then fiers child looks like :
@Entity()
@Table(name = "BANK_TRNSF_METHOD_INFO", schema = "CCARE")
@DiscriminatorValue("BankTransfer_MethodData")
public class BankTrnsfMethodInfo extends PaymentMethodData implements
          Serializable {
}     second child :
@Entity()
@Table(name = "SCRATCH_METHOD_INFO", schema = "CCARE")
@DiscriminatorValue("Scratch_methodData")
public class ScratchMethodInfo extends PaymentMethodData implements
          Serializable {
}when i persist BankTrnsfMethodInfo entity object,
automatically persisted also PaymentMethodData, but into PAYMENT_METHOD_DATA column METHOD_DATA_TYPE value is NULL. i don't understand what heppened
can anybody help me ?

I have a similar issue. I have a parent table with several child tables. Subcomponent is the parent. Term is one of the children. The parent and the children all have a CREATED_DATE column.
Two tables:
SUBCOMPONENT
SUBCOMPONENT_ID (PK)
SUBCOMPONENT_TYPE
CREATE_DATE
--- more columns
TERM
SUBCOMPONENT_ID (PK) (FK)
CREATE_DATE
--- more columns
@Entity
@Table(name = "PRM_SUBCOMPONENT")
@Inheritance(strategy = InheritanceType.JOINED)
public class Subcomponent implements Serializable {
Date createdDate
@Entity
@Table(name = "PRM_TERM")
@PrimaryKeyJoinColumn(name = "SUBCOMPONENT_ID")
@DiscriminatorColumn(name = "SUBCOMPONENT_TYPE", discriminatorType = DiscriminatorType.STRING)
@DiscriminatorValue("TERM")
public class Term extends Subcomponent implements Serializable {
}Now if I do the following:
Subcomponent subcomponent = new Subcomponent();
subcomponent .setCreatedDate(new Date);
subcomponent Dao.save(subcomponent );
Term term = new Term();
term.setCreatedDate(new Date);
termDao.update(term);the subcomponent persists fine, but and the term starts saving correctly (I see that Hibernate first INSERTS a subcomponent and then a term but I get a SQL exception: cannot insert NULL into ("PRM"."PRM_TERM"."CREATED_DATE")
The only way I can think of to work around this is to define a new field in the Term class called termCreatedDate and map that to the CREATED_DATE column on the PRM_TERM table. This seems to defeat the purpose of using inheritance. I'm using Hibernate 3.2.2 (latest version) as the JPA provider. Any ideas anyone?

What type of hard disk should I use if I want to use it on mac and windows?

Hey Forum,
I am using windows xp on my macbook (snow leopard). I came across some dealers who say that there are hard disks for mac only and for both mac and windows. So, I wanted to buy a hard disk so that I can use it both on mac and windows xp, so what type of hard disk should I use? Must I partition into 2?
or are there any harddisk in the market which is compatible for both mac and windows xp without screwing up the format(NTFS/Mac OS X Journaled)? Pls look into this matter and help me with it.
All of your replies and suggestions is much appreciated.
Thank you.

I feel I must move beyond iMovie, what program should I use ?

I have been happily using iMovie and iDVD from versions 1 through 6. iMovie 08 was so bad that Apple made iMovie 06 available as a free download for buyers of iMovie 08. The newer iMovies were better, but they seemed “dumbed down” (even for me). Now, I am shocked and horrified to learn that the latest iMovie does not even set chapter markers!
So, I have continued to use iMovie 06 and iDVD 08 (they seem to work fine under OS 10.9.4).   iMovie 06 is now 8 years old! I feel compelled to move forward. A lot of my work is DV.    In the past, most of my source material came out of S-Video.   I used a Canopus ADVC300 analog-to-digital converter that gave good results.   Going forward, I will have more video utilizing Component Video, or HDMI.
I am looking into 2 possibilities, Adobe Premiere elements 12, or.........Final Cut Pro X.
The final result of my work is almost always a DVD.   It is hard for me to move from iMovie and iDVD. I never read the manuals for either program, yet, I was able to produce DVDs with nice menus and overall quality close to Hollywood.
It looks like Final Cut Pro X 'can' make a DVD directly without other software. However, from what I have seen on YouTube the result is primitive compared to what iDVD was doing 10 years ago.
Adobe Premiere elements 12 can make nice DVDs and Blu-ray's directly. I have no problem with using a separate program to make DVDs but I haven't got a clue how to do that with Final Cut Pro X.   I suppose I can still use iDVD, but now I'm back to using discontinued software.
I do not need any of the high-powered affects capability that Final Cut Pro X possesses. My “movie-making” is mostly confined to simple editing (the old iMovie 06 did all I needed).
Frankly, one motivation for choosing Final Cut Pro X, is the excellent, compassionate and understanding support that the kind people on this very forum provide. So, what program should I use?

to turn perspective for a second by 180°:
Why do you want to switch to a new editor anyhow?
• iM-a never did discs - that was iDVDs job = no big change in your workflow
• iDVD is still working, and aside obsolete, complex and $$$$ DVDSP (part of obsolete FC/p) or Encore (part of Adobes CC rent package) your only option left to create disks on MacOS is indeed iDVD (...ok, there's Toast and Burn and some weird 'shareware'-stuff...)..
• iMovie-b supports the new HDef formats (AVCHD) - you mentioned converters and DVDs = no HDef in use, in your habitat, correct?
• if you don't need FCPX' bling-bling (I can't imagine that ) - why not using FCPX-lite = iMovie? 15$ ...
• chapters could be done in iDVD - just to mention that ............
• AP and FCPX are following very different concepts in usage - my personal preference is 200% on FCPX, … I was one of the loudest nay-sayers, when iM08 araised, meanwhile, FCPX is my dream!! AP (tested it) is way too complex, crowded, 'optionalized' and did I mention 'complex' for me. A bit like Windows vs. MacOS: 'everything goes' (incl. getting lost) vs. 'convenience' (incl. restrictions) ... After 2y of practice, I'm editing my weekly hobby-projects with 6-cam-Multicam, incl. tons of custom graphics, slow-mow, effects (soccer games) in less than 2h ... awesome!
summary:
• why switching?
• use iMovie10 + iDVD
• Premiere (or Premiere Elements!) and FCPX are both avail as fee trial ... test it - but you need iDVD anyhow
• 'disks' is a dwindling niché, for years!- consider to switch to 'other' distribution options
... what are 'chapters' anyhow??... (kid din'!)

Which C# Adobe library should I use to open a PDF in Acrobat Reader 9, 10, and 11?

Hi, all.
I have a Visual Studio C# application that writes an Adobe PDF using iText. Does anyone know how to programmatically open the PDF on client's computer and ensure it works for Adobe Reader 9, 10, and 11?
-I have Adobe Reader XI on my machine and "Adobe Pdf Reader" is NOT showing up in my COM references. This is the library that I've heard people use for this.
-The "Adobe Reader File Preview Type Library" is showing up there, but does not add to my project because of the following error message: "A reference to 'Adobe Reader File Preview Type Library' could not be added. Could not register the ActiveX type library....adoberfp.dll'." But I haven't persued this further becuase I'm not even convinced I should be using this library, which brings me to my next point:
-Please don't tell me to go read the Adobe SDK spec. In searching for this answer, I found posts on here with people asking this question and getting not great answers, or half-*** answers to go read the Adobe SDK spec. I have the Adobe SDK spec, it's terrible. The example source code is laughably poor and reads like it was written by someone with bad english, with poor naming, commenting, and documentation, and there is no separate document that explains what the source code does. I think the reason people say this is because they haven't read it themselves and they don't know the answer and hope to deal with the question by handwaving. Sorry for the rant if you weren't going to do that!
Thanks in advance, if anyone knows.
-Brandon

It will be from a client-side application, and I will be reviewing this further and get back on it. At this time my assembly isn't the correct type of 32-bit, which may be a deal-breaker. But downgrading it to 32-bit, I wasn't able to find or include the appropriate library for AXAcroPDF.
Just a word about my trying to read the SDK documentation. The documentation folder has 5 items, a folder called "Javascript", an html file caled "Acrobat_11_SDK_Help_Shortcut.html", a zip file called "...HTMLHelp.zip," pdf_reference.pdf, and U3DElements.pdf. I've never heard of U3DElements, so surely that isn't meant for me. The pdf_reference.pdf, when opened, has three PDF links to two supplements to ISO 32000-1 and a document titled Document management. These describe the PDF spec, so that's not for me. So I must have to use the HTML documentation shortcut. I open it, and my browser says the redirect URL can't be found. Ah, may be that stuff in the ZIP file it's referencing. After unzipping it, you have to move the file around so that it actually references the right index.html inside the unzipped folders, and then even after this it loads up as two blank frames in my browser. I will look into why the links are all dead, but holy lord, this is just not very helpful at all.
Thanks for your help, Test Screen Name.
