Problem regarding Bit operation

I am currently trying new approach to speed up my current operation, for this I have to know the bit operations :-( but I am having trouble in finding the references for that.
Can you please send me some references regarding bit operation.
Thanks for taking keen interest in this post.

By default, commit operation will save all rows to db. You can write update query in a button
by taking jdbc connection reference from environment. After updating row in db you should
refresh your ADF UI to see changes.
You can use this code for creating db connection.
                InitialContext initialContext = new InitialContext();
                DataSource ds = (DataSource)initialContext.lookup("java:comp/env/jdbc/conDS");

required: byte
byte c =        a & b;
                         ^

     byte b = 0x10;
     byte c = a & b;
     System.out.println(c);
          }I'm using byte don't know whyt it found's a int. Thanks

[JLS 15.22.1 Integer Bitwise Operators|http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.22.1] says:
When both operands of an operator &, ^, or | are of a type that is convertible (§5.1.8) to a primitive integral type, binary numeric promotion is first performed on the operands (§5.6.2). The type of the bitwise operator expression is the promoted type of the operands.
So, since byte is a primitive integral type, binary numeric promotion occurs, and both are converted to int, and the result is then int. You can't assign an int value to a byte variable, unless it's a compile-time constant, so you have to cast.
byte c = (byte)(a & b);Edited by: jverd on Oct 6, 2009 1:19 PM

HP Laserjet p2015d auto duplex printing with Windows 7 64 bit operating system

I have used the HP Laserjet p2015d with Windows 7 32 bit operating system and have been able to use the AUTOMATIC DUPLEX feature of the printer without problems.
Now, however, I have installed the 64 bit version of Windows 7 operating system and the AUTO DUPLEX does not work and is not shown as being available on the PROPERTIES menu of the printer.
Is it possible to use the AUTO DUPLEX feature of the printer with Windows 7 64 bit operating system.
All replies welcomed! Aaron in Calif.

Hi Aaron,
Make sure the Automatic Duplexing option is enabled:
Enter Control Panel > Devices and Printers.
Right click the printer icon, then click Printer Properties.
Click the Device Settings tab.
Set the Automatic Two-Sided Duplex Accessory as installed and click OK to save the change.
Now Automatic Duplexing should become available.

How to fix "A 32-bit agent is installed on 64-bit operating system" alerts

Hi
We have installed SCOM 2007 R2 CU1 in our environment (by properly following installation sequence given on the CU1 web page). After manually installing agent update of CU1 on 64 bit servers, we are getting alerts "A 32-bit agent is installed on 64-bit
operating system" and the status of these 64-bit servers remains in Warning state. We have manually uninstalled and reinstalled 64-bit agent as well as 64-bit CU1 agent update but still the status is in Warning state. We can not completely uninstall cluster
node agent, remove it from the console and reinstall agent from scratch because SCOM R2 is not allowing to do clean uninstall and reinstall of agent on cluster nodes.
If anyone faces similar problem and have fixed it then please let me know the solution so i can also fix the issue.
Thank you
HRP
Thanks & regards, H R Parikh

This new(er) monitor is set to generate when the registry key "HKLM\SOFTWARE\Wow6432Node\Microsoft\Microsoft
Operations Manager\3.0\Setup" is found on a 64-bit Windows server. We have several alerts like this as well, but found it had little to do with the CU1 patch and
more to do with rolling out the updated Operations Manager management pack (v6.1.7599.0) at around the same time as well as the server having had a 32-bit agent previously installed at one point or another. We are looking into simply removing the 32-bit
key, but have not done so just yet as we need to test this theory on a dev server first. Of course, to be safe, we could always uninstall the agent and patch, delete the keys manually, and then reinstall.
Hope that helps.

Facing Problem Regarding UTL_SMTP

Hi Tom,
i have a program(PL\SQL code) which dynamically picks up the mailhost, generates the To list and from list and constructs an attachment of iREC external applicants and mails it to HR Manager.But the program is getting error like below just after the construction of the attachment.
ORACLE error 29277 in FDPSTP
Cause: FDPSTP failed due to ORA-29277: invalid SMTP operation
ORA-06512: at "SYS.UTL_SMTP", line 43
ORA-06512: at "SYS.UTL_SMTP", line 279
ORA-06512:
Affected line : marked by * (Code logic Flow)
-- Construction of mail body ----

UTL_SMTP.close_data(e.mail_conn);
UTL_SMTP.quit(e.mail_conn);
END IF;
but while i'm running the same code by providing the to, from and mail host name hardcoded the program is executing smoothly and sending mail as well.
The code runs fine on the other instances but in my instance is gets error out.is this a problem regarding the UTL_SMTP settings in my instance?
I couldnt find any valid reason for this error.would you please help regarding this?
P.S. it's bit urgent.

Tom is out chasing Jerry.

Ram utilization with 64 bit operating system

Attached is the current configuration of my 8.1 Pro PC & I have a question regarding RAM utilization with 32 bit programs running on this PC.
It has been my understanding that the 32 bit OS (XP Pro), at best, would be able to only utilize 4GB of RAM memory.
I've recently built a PC for the specific task of running an application which is very CPU & output intensive. The application is a Windows based 32 bit application which analyzes and recovers data from NAND chips. Input data comes from a 2.0 USB
feed, is processed and is then written to a 2 disk raid array.
Will the 64 bit operating system enable 32 bit applications to utilize more than 4GB of RAM memory? Any suggestions on how to maximize the processing of 32 bit application on a 64 bit OS would be appreciated.

Hi,
As far as I know, 32-bit application running on x64 Windows system had a limit of memory address space. The max usage of RAM is 4GB. I also make a test using testlimit:
According to the screenshot, we can find that, 32-bit testlimit only can leak 4051MB memory, while 64bit testlimit can achieve to 5200 even more larger memory.

Whether postgresql-8.2-506.jdbc4 works in a 64 bit operating system?

Whether **postgresql-8.2-506.jdbc4** works in a 64 bit operating system?
Especially I would like to know whether it works in windows server 2008 64 bit operating system.

The Driver is produced by them, they should know. I don't believe it would be a problem, but all you can do is try it.Agreed.
The postgresql JDBC driver is a type 4 driver and therefor a pure Java implementation without JNI dependencies. That should work without problems on a 64 bit system.

INdesign and 64 Bit Operating Systems

Been having problems with my INdesign, and the tech people on the support line said it is because I have Vista 64 bit operating system. This sounds very strange to me, as INdesign is the industry standard, and 64 bit operating systems are the norm. Does any one else have experience trying to run INdesign on a 64 bit system?

Bob's right; I'd suggest ignoring the 64-bit issue and just getting familiar with coming to the forums for assistance. I've worked phone tech-support jobs before; phone support reps are judged by how fast they can get you off the phone, and if you start the call with "Hey, I'm running ID on a 64-bit system" then they can get you off the phone immediately, so you just gave their call-time metrics an easy statistical boost.
1) So, yeah, the baseline grid will cause stuff to snap to it if you have that setting turned on in the "Grids & Guides" section of the View menu.
2) "Manual overrides" means that you can format text manually by clicking on the Font menu, and that will cause your formatting to diverge from what is defined in the style. Take a look at the style name; does it have a little plus next to it? That means that the text you've selected diverges from the style. Clear the overrides to return the text to the settings in the paragraph style. You can do this with an alt-click on the style name, or by clicking on the options pulldown in the Paragraph Styles panel and choosing "Clear Overrides." I do it so often that I have a keyboard shortcut set up to do it (in Edit -> Keyboard Shortcuts).

Hi claire.winteringham,
If you have a 64 bit machine then there shouldn't be any problem while installing any 32-bit software.
Try to download it with the below mentioned link :

ID3v2: Programmers' habits when describing bit-operations

Hi.
I'm trying to implement a class that can read ID3v2 tags from MP3 files. The id3.org site seems to be the only source on the net where you can get information about the organisaton of ID3 tags.
Unfortunately I haven't worked with bit operations before and get quite confused about the fact why so many programmers describe the order of bits in octal values.
Let me quote a part of the description of ID3v2:
The ID3v2 tag size is encoded with four bytes where the most significant bit (bit 7) is set to zero in every byte, making a total of 28 bits.
I could understand that part. But the following leaves a huge question mark over my head...
The zeroed bits are ignored, so a 257 bytes long tag is represented as $00 00 02 01. ... An ID3v2 tag can be detected with the following pattern:
$49 44 33 yy yy xx zz zz zz zz
Where yy is less than $FF, xx is the 'flags' byte and zz is less than $80.
Can somebody of the veterans try to help me understand the first line, where the author describes in octal basis how these four bits are structured? Moreover I'd like to know what advantages it has to express bytes in octal values.
Regards,
Wan-Hi

...why so many programmers describe the order of bits in octal values.I doubt it. The endianness of data is either big-endian or little-endian (x86).
The ID3v2 tag size is encoded with four bytes where
the most significant bit (bit 7) is set to zero in
every byte, making a total of 28 bits.
The zeroed bits are ignored, so a 257 bytes long
tag is represented as $00 00 02 01.
That's not octal. it's hexadecimal.
0x00 0x00 0x02 0x01
In binary
0000 0000 0000 0000 0000 0010 0000 0001
Strip out the msb in each byte
x000 0000 x000 0000 x000 0010 x000 0001
and you you are left with 28 bits
0000000000000000000100000001
or
0000 0000 0000 0000 0001 0000 0001
or in hexadecimal
0x0000101
or in decimal
257
