When and why should I combine functions in a package?

I have asked this question informally of a few people who "should know", but never been given an intelligent answer :-( Nor have I found a significant discussion -
Can anyone provide some insight?
Thanks, George

Good education on Advantages mentioned. Andrew's note on performace is interesting.
Following does not fall under the Advantages, but some thing which I want to bring to expert's notice to see what could be the rationale behind it.
AND You guys must have already noticed this,
It is required by oracle that each proceduce/funtion mentioned in the package SPEC must be defined in the BODY, BUT it is not the case with vice versa. We can define a procedure or funtion in a BODY with out specifying it in the SPEC. However we can not publicly use such procedure or function. We could use it privately with in the procedures of the package, more like private methods of C++ Class. Oracle may be simplifying on specification part of it.

When and why should I verify disk permissions?

I was told by HP to check my permissions and to repair ? what does this do and is there any harm in doing it?
thanks

It repairs permissions. It is not harmful. What HP product are you using that this would be for?
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Vectors gone? When and why?

I have read in a couple of posts that Vectors are "legacy" and may not be around forever. Can anyone shed light on the when and why of this? I am relatively new to JAVA programming but I do have a bunch of applications out there that use Vectors. I personally found them very easy to work with.
Thoughts?

Wow! I can't wait for Java 2.0! (Please read heavy sarcasm.)
Speaking of rumors, let's not start spreading any rumors that the Java group at Sun has actually started to talk about -- let alone publicly announced -- that a 2.0 version is in the works; 1.5 sounds right to me.
I know that you can get almost the same functionality out of a List that is returned from the Collections.synchronizedList(List) method as you can out of a Vector, but Vector is by no means a deprecated class. (We should try to be careful about the casual use of meaning-laden words.) pengjuc is right that a lot of Swing (and non-Swing) classes such as JTable rely on Vector; the mere rewrite to replace all the Vectors with ArrayLists would probably require a Java release all on its own (and whose to say that ArrayLists are really all that, anyway?). Moreover, Vector is part of the public API of many classes and to deprecate it would throw a lot of developers into a tizzy because it would potentially break the ability of their applications to upgrade to a new version of Java. There is nothing inherently wrong with Vector -- it performs as advertised -- and pengjuc is right again that the performance differentials are minute over small object collections.
In response, again, to dubwai, there's a difference between using Vectors as a developer and having them included in the J2SDK. If you don't like them don't use them, and if you don't like them in other classes, rewrite those classes to your taste. Personally, I think you either have to take what you're given, do it yourself, or get involved in the process.
Good luck, All!

When and Why do we need to build a CUSTOM CUBE

Hello Experts, Could some please explain with a scenerio ..
"When and Why do we need to build a CUSTOM CUBE"
Thanks in advance
Bhalout

When and Why:
Custom cube should be think of when the constent cube is either not suitable nor available for a subject area.
If there is a content cube and but does not meet your reporting needs, then the better thing will be to adopt the content one and make changes.

When and Why Do We Need to Create 2 Diff iTunes Libraries?

Hi,
When and Why Do We Need to Create 2 Diff iTunes Libraries?
Thanks.
Ed

There's no fast rule sayng you must, and I suspect most people only use one.
You might want to set up a second library if your first one is so huge that it is slow to operate. Split your media. For example, I don't listen to classical and rock music at the same time and could restart iTunes ffrom a different library when the time came to switch.
I have a few extra libraries. One's for music I organized for a special occasion but don't really listen to myself and don't want it cluttering mine. I also have a special library for my mp3 player (not an Apple model) with its own set of files which match some in my main library but they are tagged differently to be compatible with the player's quirks.
I could also see having a different library for files on an external drive if you have some on your internal drive too. You might, for example, have a bunch of movie files on an external drive that you don't normally need to have plugged in all the time and don't want iTunes giving you a bunch of exclamation marks if are using it to play your music media on your internal drive.

The exit is only for Internal SAP use this is why you don't find any documentation for it. So you don't need

HTMLDB trimming - when and why?

Hi, I recentrly found that I couldn't delete one row that I entered within my htmldb app.
It turned out that when I was inserting this row I've entered a value (varchar2) beginning with space. However on displaying the space was trimmed. And my delete process did not even fail (It gave something like "Process concluded successfully!") which was a pure lie. :-)
The proces is "DELETE FROM MYTABLE WHERE MYFIELD = :P99_MYITEM";
I am using version 1.6
Please tell me is this a bug and why am forced to use trim on every insert process.
Please don't tell me to use numeric ID for a key because am not the designer of this table.
If there is an automatic trim, why isn't it used when the value is inserted or why is this trim used at all if this space is part of the value?
10x.

Sounds like this has very little to do with HTMLDB. The VARCHAR2 datatype will contain exactly what you put in it (if you insert a value with a leading space, that's what you'll get). Also, your delete did not really fail (which would indicate a error of some kind), it merely resulted in zero rows deleted.
There is no automatic trim, but you can code this functionality into a trigger or stored procedure.

When and Why Did Apple Drop The 160GB Classic Ipod

Hi
I was going to go and finally buy a 160GB Ipod tomrrow.I see they don't even list it anymore on Apples site and Future-shop doesn't even list it on the site.
They only make a 120GB Now
When Did they Drop this and why???
Also Do any stores still have them in Stock???
I won't be spending the money on only a 120GB if thats all they make now
I've had my Ipod Mini 4GB since 2005 and thought it was time for a upgrade.
Please do tell me if Apple still makes the 160GB Ipod
thanks

Apple has discontinued the 160GB. You can buy one online still, but not from Apple. Or buy a used one off Craig's List.
P.S. Actually Apple is still selling refurbished 160GB on it's site, if you want to go that route. I also found some new ones on Amazon. Buy.com may have some too.

When and why did they decide to lobotomize Siri

Siri used to amuse me when I was bored. She sang, she told jokes. It was fun to look for the easter eggs. not anymore. Which doofus came up with this plan and why.

None of us here would know, we are users like you. If you would like to provide feedback to Apple about your concerns, you may do so at www.apple.com/feedback and click on the appropriate link.

When and why do i have to use a Network-Path?

Hello,
i'm wondering when i why i have to use a Network-Path in KM.
I'm able to connect to a File-System Repository, even if i have no Network-Path defined.
- both run on W2K Server
- EP runs on host EP (not an Domain-member)
- Filesystem is provided by host FS (Domain-member)
- EP is started with the default local-user SAPServiceEP6
- on the FS host, i have defined also a local-user SAPServiceEP6 (because EP always wants to logon with these credentials, i have checked this in the windows securitylog of host FS)
- no network-path defined
So regarding the fact, that everything is working, can anybody tell me when i have to use a Network-Path?
Thanks in advance
Frank

Hi,
for example if you want to access a share that only access is granted for a given user. The idea is having a superuser with privileges on the other computer to do things like checking ACLS.
Another example, how can you access windows shares when running the portal in Unix? Using a network path.
REgards,
Miguel

What is BitLocker and Why Should We Use It in Windows 7 Ultimate & Windows 8 ?

Hello ppl. Today, I'll try to tell you about BitLocker function in Windows 7 Ultimate & Windows 8 in clear words. When we save a document in our harddisk folders these info are easily can be acquired by a hackers if your system is insecure though a good hacker can beat all kinds of antivirus and firewall software. But !!!
If your data are saved encrypted on your harddisk, it is impossible to see that data though these clever guys stole your sensitive info. Because the data can not be seen without a log in password if they have been saved with encryption!!! So here is what BitLocker does!!!
BitLocker saves all your information by encrypting them so you dont have to worry about your sensitive data anymore! Even if they are stolen by other ppl, it's impossible to see your valued work sheets or other personal data such as pics and bank account information as long as you have a good BitLocker password like A3#Be$%Er or whatever.
BitLocker is a standart feature added to Windows 8 but you should upgrade to Windows 7 Ultimate to use it in Windows 7.
I'll also start a topic about how to activate BitLocker in Windows 8 shortly.
I try to tell in clean words when I create a topic to help those who have basic knowledge about IT. I hope this helped. If you still have questions about BitLocker please dont hesitate to ask me about them.

Hi
Thank you for your post . This is a good information which can help users to be protected from hackers
Cheers!!!

Rethrowing the same exception - how, when and why?

Hi,
I have just gone through the Exception Handling chapter and found don't understand when should I use the rethrowing of same exception?
e.g.
catch(NullPointerException e) {
e.printStackTrace();
throw e;
or
catch(NullPointerException e) {
e.printStackTrace();
Throwable changedE = e.fillInStackTrace();
throw changedE;
I am not sure how, why and when should I use this syntax?
Any advice and a given example is much appreciated.
Thanks in advance.
gogo

Think about the information you would want when this exception occurs; if you rethrow the exception then the entire stack trace will be available which will allow you to find the root of the problem more easily than if you have filled in the stack trace at an intermediate point in the call graph. Never throw away information in an exception.
Note also that fillInStackTrace() does not actually create a new instance of the Throwable. It just returns the same instance but with it's stack trace modified.
There are two other points to note about your example:
First, catching NullPointerExceptions or any subclass of RuntimeException (except for the curseworthy NumberFormatException) is generally a bad thing to do. RuntimeExceptions usually indicate that something is wrong with your code or with the VM and catching them is just masking the real problem. They're not like checked exceptions (subclasses of Exception that are not RuntimeExceptions) which can occur because of something 'unexpected' happening in the environment which has nothing to do with bad code and for which recovery from the problem is often possible.
Second, consider whether you really want to catch an Exception anyway. Exceptions should only be caught when:
a) you want to try to recover from the problem i.e. you can handle the exception
b) you want to transform the exception into something more meaningful to client code, i.e. if the exception comes from deep in some library code and you can't handle the exception but the actual class of exception won't be meaningful to the client code, then you might want to create your own Exception subclass and throw an instance of that in place of the original exception. If you do this, then you should chain the original exception so that you still preserve all the stack information and the original message (this is why all Throwables in JDK 1.4 have constructors that take a Throwable 'cause' parameter)

When and Why we use BAPI, RFC and IDOC.. in XI

Hi,
Could any one tell me why we some time use BAPI, and some times use RFC and some times use IDOC while communicating with the SAP systems.
Is there any differences while using the same.
regards,
Sunil

Sunil,
RFC and BAPI are same as per the technical point of view both are remote enabled function module..
BAPI is provided by SAP while RFC is created by a developer..
IDoc is another proprietary technology of SAP for exchnaging messages .
Difference lies here :
1. For RFC/BAPI you need to use RFc adapter
while for IDoc you need to use IDoc adapter..
2. For RFC you need to create RFC destinations not for Idoc
3. For Idoc you also need to manage Partners Profiles..inn R3..
These are few differences in using RFC/BAPI and Idoc...not the only ones..
Feel free for any clarification..
Regards,
