Query on Swing Concepts

hello all,
i am unclar about swing container concepts w.r.t content panes, root panes, layered panes and glass panes.
could anyone throw light on the same in simple language.
i have gone thru many tutorials and i am unclear including sun website.
under what situation would we use these diffrent panes.
also clear difference between lightweight and heavyweight componets of awt and swings.
thanx in advance.

I can explain the second part of your question "differance between lightweight and heavyweight". Lightweight components are components that have no dependance on native GUI elements from the underlying Operating System, they are drawn directly by pure java drawing routines. On the other hand heavyweight components are dependant on an OS native "peer" object for some functionality. This makes heavyweight objects have a higher memory footprint.

Query on Oracle Concepts: Advantages of ASSM

Hi,
A query on Oracle Concepts, specifically on Advantages of ASSM.
While I am able to understand 'Simplified administration' & 'Increased concurrency', can anyone mention this in simple terms:
• Dynamic affinity of space to instances in an Oracle Real Application Clusters (Oracle RAC) environment.I guess I know whats Oracle RAC but what it meant by 'Dynamic affinity of space to instances'?
Regards,
Ankit Rathi

Hi Aman,
I was going through Oracle® Database Concepts 11g Release 2, Chapter 12 Logical Storage Structures (link below):
http://docs.oracle.com/cd/E11882_01/server.112/e25789/logical.htm#i19599
*Automatic Segment Space Management*
The ASSM method uses bitmaps to manage space. Bitmaps provide the following advantages:
•Simplified administration
ASSM avoids the need to manually determine correct settings for many storage parameters. Only one crucial SQL parameter controls space allocation: PCTFREE. This parameter specifies the percentage of space to be reserved in a block for future updates (see "Percentage of Free Space in Data Blocks").
•Increased concurrency
Multiple transactions can search separate lists of free data blocks, thereby reducing contention and waits. For many standard workloads, application performance with ASSM is better than the performance of a well-tuned application that uses MSSM.
•Dynamic affinity of space to instances in an Oracle Real Application Clusters (Oracle RAC) environment
ASSM is more efficient and is the default for permanent, locally managed tablespaces.Regards,
Ankit Rathi

Syntax error in OBIEE generated Physical query - Advance filter concept

I encountered a syntax error when running a report with the help of advanced filter concept.
I am getting syntax error at the physical query generated by the OBIEE for main report.
I used a sub report with the help of advanced filter concept in main report.
I am posting the physical query for the convenience.

I executed the query against my database(sybase) in query tool. It showed error.
I took out the column alias generated by the OBIEE ("as c1" as underlined). Then the query is working fine.
How to disable OBIEE from generating the alias.
Is there any way to do it.
If obiee is generating the physical query, i am suprised to see a syntax error.
The bold part is the query from Intermediate report
I underlined the problematic part.
Please help me. This is an urgent reuirement,
Thanks in advance for the help.

HI,
When I execute the query on query tool ( my database is sybase)
I am geting error at "as c1" part, as underlined in the query.
when I remove that and execute the query, It is generating the output.
here is the better view of query and error:

Query on Oracle Concepts: Table Compression

The attributes for table compression can be declared for a tablespace, table, or table partition. If declared at the tablespace level, then tables created in the tablespace are compressed by default. You can alter the compression attribute for a table, in which case the change only applies to new data going into that table. Consequently, a single table or partition may contain compressed and uncompressed blocks, which guarantees that data size will not increase because of compression. If compression could increase the size of a block, then the database does not apply it to the block.
Can anybody please explain text marked as bold? How can data-size/block-size can increase by compression?

First let's be clear on what is being said. The doc says this:
>
If compression could increase the size of a block, then the database does not apply it to the block.
>
That is misleading because, of course, the size of the block can't change. You should really read that as
>
If compression could increase the size of the data being stored in a block, then the database does not apply it to the block.
>
There is overhead associated with the compression because the metadata that is needed to translate any compressed data back into its original state is stored in the block along with the compressed data.
The simplest analogy (though not a perfect one) is the effect you can get if you try to zip an already highly compressed file.
For example, if you try to use Winzip to compress an image file (jpg, gif, etc) or a video file you can easily wind up with a zip file that is larger than the uncompressed file was to begin with. That is because the file itself hardly compresses at all but the overhead of the zip file adds to the ultimate file size.
I suggest you edit your thread subject since this question is NOT about partitioning.

Swing is GUI library for use in desktop applications.
JSF is a web application framework which runs on an application server and is accessed by clients via web browsers.
To fully understand what you have done, try accessing your application from a different machine than the server.
To answer your question, don't invoke System.exit() if you would like the process to continue. But that is the least of your problems.

Dynamic Querying in ESB

Hey,
I am trying to implement dynamic querying using the query by example concept. My requirement is as follows:
"Say I have 5 inputs , I need to fetch rows from the database using those 5 inputs as a part of my where clause"
The user input are optional. Hence using the query by example concept I was able to filter rows.
But the problem is as follows:
1) I have a "time from" and "a time to" field as user inputs. I need to filter the fetched rows so that time is in that time range only. I do not know how to implement this also along with the above concept as there is no place for a where clause.
Any help/suggestions would be appreciated.
Thanks

Hide a column in BW Query

Hi Gurus!
I'd like to hide a column for specifics users in a BW Query.
I flagged the InfoObject as Auth. Rel. and created an analysis authorization. I ran the query but I got "No authorization", when I checked the log I saw that the query is asking for full authorization value to that InfoObject. I tried with : (semi colon) value but I got the same result.
Is there any way to hide a column in a query (with authorization concept) avoiding to redisign a new query?
Thanks in advance.
Best regards,
Pepe

For your existing query, above two are conflicting. So guess you have to move with redesign/new query.

Google-Suggest in Swing Desktop Application - Possible?

Hi All,
I am building my first Java Swing Application. Apologies in advance for any stupid questions I ask w.r.t. Java Swing concepts.
I am building a Billing Desktop Application using Java Swing. My backend is a Microsoft Excel. My clarification are:
*1. I have a set of values in a combo box listed below a jTextField. The values have to be displayed on the Screen as and when the user gives some characters as input. In short, something like a google-suggest functionality.*
*2. Generate pre-defined set of jLabels and jTextFields on the click on a jButton*
If this is too much to achieve with Java Swing, I would highly appreciate if you can share any other means to achieve this.
Thanks,
Vikas

Here's one way to do that:

     SELECT     itemcode
     ,     month_id
     ,     COUNT (DISTINCT month_id) OVER (PARTITION BY itemcode)     AS cnt
     FROM     table_x
SELECT     itemcode
,     month_id
FROM     got_cnt
WHERE     cnt     >= 4
;If you mean something else (such as all the monthids have to be in a series, with a difference of 4 between successive monthids), then explain more clearly.

What is the "best" swing book or e-book?

I am looking for a good book that will teach me the basics of creating simple swing GUI's. I want the book to have good examples and not move too fast, as well as give a detailed explanation of what's going on. I am familiar with basic java so I want a book that only covers swing concepts.
What swing books have you read and were they good? Please suggest any books and why you suggest them.
Thank You for your time.

its true that there is nothing better than the JAVA TUTORIALS but for examples
you can go to [JAVA2s|http://www.java2s.com/Tutorial/Java/0240__Swing/Catalog0240__Swing.htm] swing section which is a good place to have examples that will clear your idea/concepts
but prefer SUN tutorial as first place to start.

Question on swings help me

Hi to all i am new to swings concept my problem is
I taken 8 subjects with 100 marks and 5 labs with 75 marks in my application.
Know my problem is when i am calculating subjects and labs i am not getting average .
And but when i am calculate total divided by 13 i am getting average.
For example : 8 subjects total is 560.
5 labs total is 250.
average = total/13
i am getting average.
But i want average like this i.e average = total /1175;
i am taken total = subjects + labs;
help me regarding this topic
Thanks in advance

Hello
u r did "average = total/13; " this avg is not correct one .....
bcos 8 subj is respect to 100 and remaining is respect to 75 .
avg = (getting total marks / totalmarks)*100
this is the correct way to calculate avg
i am taken total = subjects + labs;
all the best
regards
Amir
