Question about PGA and TEMP usage

hi,
we had a situation whereby OEM was reporting that because the PGA was too small during a time frame that extra I/O on the TEMP was being created. Does this then mean that the TEMP was acting as a pseudo PGA.

Newbie question about component and UDF usage.

This will be the 1st time I'm coding a component and UDF. I
kind of understand the concept but not sure about how to write it
in detail.Such as passing the parameter, etc.
I'm starting to write a user login, verifying users before
allowing them to enter into the app.
So I have 2 fields in my login form, Login and password.
Upon submitting this form, on the actionpage.cfm I'm calling
a component. This is how I call the component:
<CFINVOKE Component="cfc/loginaction"
Method="AuthentiCateUser" ReturnVariable="UserInfo">
Then in my Component I have the following:
<CFCOMPONENT>
<CFFUNCTION Name="AuthentiCateUser" RETURNTYPE="Query"
hint="Use for user login">
<CFARGUMENT Name="login" Type="Structure"
Required="true">
<CFARGUMENT Name="password" Type="Structure"
Required="true">

<CFQUERY NAME="Authenticate" DATASOURCE="sendfast">
SELECT * FROM tblcustomer WHERE Login = '#Login#' AND
Password = '#Password#'
</CFQUERY>
<CFRETURN AuthentiCateUser>
</CFFUNCTION>
</CFCOMPONENT>
When I run this code, I got error, it said :
The parameter LOGIN to function AuthentiCateUser is required
but was not passed in.
The error occurred in
C:\CFusionMX\wwwroot\KDt_Mod\userloginaction.cfm: line 18
16 : <CFSET
UserLoginInfo["Password"]="#Form.Password#"> 17 : 18 :
<CFINVOKE Component="cfc/loginaction" Method="AuthentiCateUser"
ReturnVariable="UserInfo">
19 :
My question is:
What should I do in order to pass #Form.Login# and
#Form.Password# to my UDF within my component?
I'm using CFMX 6 and Micrisift SQL 8

I've applied cfinvokeargument and my login and password were
passed to my component.
But I'm facing new problem: Where should I write my
authentication? should I write user authentication within my
component or
loginaction.cfm (the calling template)
What I mean by authentication is something like this:
<CFIF #Authenticate.RecordCount# IS NOT 0>
<cfset session.CustomerID
="#Authenticate.customerid#">
<cfset session.Name ="#Authenticate.Name#">
<CFCOOKIE NAME="UserLoginIn"
VALUE="12345_pn#Authenticate.customerid#">
<cflocation url="index.cfm?loc=home">
<CFELSE>
<script language="JavaScript">
alert("Username/password is not found, plese try again");
history.go(-1);
</script>
<cfabort>
</CFIF>
If I keep this code in my loginaction.cfm what is returned
from my function is not recognized by the component, the error said
Authenticate.RecordCount is not recognized.
Also I'm still confuse with what should I put in the
RETURNTYPE. If I put query, it gave me error, also, what is
returned by CFRETURN.
This is my component:
<CFCOMPONENT>
<CFFUNCTION Name="AuthentiCateUser" RETURNTYPE="Query"
hint="Use for user login">
<CFARGUMENT Name="login" Type="Structure"
Required="true">
<CFARGUMENT Name="password" Type="Structure"
Required="true">

<CFQUERY NAME="Authenticate" DATASOURCE="sendfast">
SELECT * FROM tblcustomer WHERE Login = '#Login#' AND
Password = '#Password#'
</CFQUERY>
<CFRETURN AuthentiCateUser>
</CFFUNCTION>
</CFCOMPONENT>

Question regarding roaming and data usage

I am currently out of my main country of service, and as such I have a question regarding roaming and data usage.
I am told that the airplane mode is sufficient from keeping the phone off from roaming, but does this apply to any background data usage for applications and such?
If the phone is in airplane mode, are all use of the phone including wifi and application use through the wifi outside of all extra charges from roaming?

Ann154 wrote:
If you are getting charged to use the wifi, then it is possible. Otherwise no
Just to elaborate here, Ann154 is referring to access charges for wifi, which is nothing to do with Verizon, so if you are using it in a plane, hotel, an internet cafe etc that charges for Wifi rather than being free . Verizon does not charge you (or indeed know about!) wifi usage, or any other usage that is not on their cellular network (such as using a foreign SIM for example in global phones) So these charges, if any, will not show up on the verizon bill app. Having it in airplane mode prevents all cellular data traffic so you should be fine

A few questions about MacBooks and Parallels Desktop.

I have a few questions about MacBooks and Parallels Desktop.
1) I understand I need at least 1GB of RAM to run Parallels Desktop but what about the hard drive, is the stock 60GB drive big enough?
2) Related to question 1, even if it was big enough to allow me to install and run Windows would the 60GB drive be enough if I wanted to install a Linux distribution as well?
3) This has nothing to do with Parallels Desktop but thought I'd ask it here anyway, do Apple Stores carry just the stock MacBooks, or do they carry other configurations?
Thanks
Keith

1. Depend on how intensive you use that HD for saving data on both Mac OS and XP. For standard installation on both OS X and XP, the space of 60 Gb is enough.
2. Same answer as no 1. You can install all three on that HD space, but the extra spacce available will be less and less for your data. You can save your data on external or back up on cd/dvd and erase it from the HD to keep the free space.
Remember to leave at least 2 or 3 Gb for virtual memory usage.
3. Just call them, maybe they don't have it in store stock, but by appointment they might configure one for you before your pick-up date.
Good Luck

A question about grub and USB

Hi All
I have a quick question about grub and USB that I can't quite find the answer to by searching. Most of the FAQs discuss booting a full linux dristribution from USB. My situation is this. I am getting a new computer with two drives, the second will be arch and the first will be Vista (for my wife). I want the computer to boot the same way that my wife's machine boots at work so I don't want to install grub on the MBR. So, is there a way to have all of the grub config files and kernels installed on the second drive and simply install to grub boot loader to the MBR of a USB stick? My goal would be to simply plug the USB stick into the new PC and boot arch from the second drive.
Thanks
Kev

i cant say for hp's
havent worked on any in a while
recent machines have been coupleof dell's , vaio & emachine
which dells do offer it at least the ones i tried , my laptop does(dell)
all home pc's are built by me which do offer to boot individual drives
what hp you getting it may tell in specs
are both discs sata? if so it might not offer this option with 2 drives of same interface
check your power supply alot of these preconfigured machines put cheap under reated power supplies in there
& will burn your motherboard i just replaced PS(250 watt) & mobo(845gvsr) in an emachines <cheap stuff<
i hope you researched the pc before buying ie : mobo, power supply are the biggest concerns
i find it much more benificial to build my own machine gives me peace at mind. the cost is sometimes more in $ but not always , your biggest expense is time researching hardware
if you live in usa the best places to start looking are bensbargains.net & pricewatch.com
i am not affiliated with either & niether sell the hardware they are just advertisers a place to buy
for costomized machines that i would trust is unitedmicro.com theyll asemble & test before shipping
i have gotten 2 machines so far from them with NO PROBLEMS with hardware (knock knock)
you may want to consider this in your next venture for pc

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM... I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM? Is there any way to get more VRAM to play games on steam?

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM...
I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM?
Is there any way to get more VRAM to play games on steam?
I've learned by reading other topics that I can't upgrade my graphics card on my Macbook Pro because it's soldered into the motherboard or somthing like that, but please tell me if there is any way to get more video ram by chaning some setting or upgrading something else. I'd also like to know why I only have 256MB of VRAM when I have 8GB of RAM, since I have 8GB of RAM I thought I was supposed to have 560mb of VRAM...
So the two questions are...
Is there any way to upgrade my VRAM, so that I can play games on steam?
Why do I only have 256MB VRAM when I have 8GB total RAM?
Other Info:
I have a quad core i7 Processor.
My graphcics card is the AMD Radeon HD 6490M.
I am also trying to play games on my BOOTCAMPed side of my mac, or my Windows 7 Professional side.
THANK YOU SO MUCH IF YOU CAN REPLY,
Dylan

The only two items that a user can change on a MBP are the RAM and HDD (Retinas not included). You have what the unit came with and the only way you will be able to change that is to purchase a MBP with superior graphics
If you are very much into gaming, the I suggest A PC. They are far superior for that type of application to a MBP.
Ciao.

One question about Pricing and Conditions puzzle me for a long time!

One question about Pricing and Conditions puzzle me for a long time.I take one example to explain my question:
1-First,my sale order use pricing procedure RVAA01.
2-Next,the pricing procedure RVAA01 have some condition type,such as EK01(Actual Costs),PR00(Price)....,and so on.
3-Next,the condition type PR00 define the Access Sequences PR00 as it's Access Sequences.
4-Next,the Access Sequences PR00 have some Condition tables,such as:
     table 118 : "Empties" Prices (Material-Dependent)
     table 5 : Customer/Material
     table 6 : Price List Type/Currency/Material
     table 4 : Material
5-Next,I need to maintain Condition tables's Records.Such as the table 5(Customer/Material).I guess the sap would supply one screen for me to input the data of table 5.At this screen,the sap would ask me to select one table,such as table 5.When I select the table 5,the sap would go to the screen to let me input the data of table 5.But when I use the T-CODE VK31 or VK32 to maintain Condition tables's Record,I found it's total different from my guess:
A-First,I can not found one place for me to open the table,such as table 5,to let me input the data?
B-Second,For example,when I select the VK31->Discounts/Surcharges->By Customer/Material,the sap show the grid view at the right side.At the each line of the grid view,you need to select the Condition Type at the first field.And this make me confused very much.Why the sap need me to select one Condition Type but not the Condition table?To the normal logic,it ought not to select Condition table but not the Condition Type!
Dear all,I'm a new one in sd.May be this is a very stupid question.But it did puzzle me for a long time.If any one can explain this question in detail and let me understand the concept,I will appreciate him/her very much.Thank you.

Hi,
You said that you are using the T.codes VK31 or VK32.
These transaction codes are used to enter condition records for standard condition types. As you can see a grid left side having all the standard condition types like price, discounts, taxes, frieghts.
Pl check using T.code VK11 OR VK12 (change mode)
Here you can enter the required condition type, in the intial screen. (like PR00, MWST, K004, K005 .....etc)
After giving the condition type, press enter or click on Combinations icon on top of the screen. Then you can see all the condition tables which you maintained for that condition type. Like as you said table 118, table 5, table 6 and table 4.
You can select any table and press enter, then you can go into the screen in which you have all the field cataglogues you maintained for that table. For example you selected combination of Customer/Material (table 5) then after you press enter then you can see customer field on top, and material fields.
You can give all the required values and save the conditon record.
Hope this is clear.
REWARD IF HELPFUL.

2 question about GPU and Lens correction ,cs5

Hi
i have 2 questions about Gpu and lens correction in Cs5
1)Filter->lens correction->search online
i get often and almost every connection time out at the first click on search online , at the second click i get no online profile
is it normal?
2) question is about Gpu
it run faster , but talking about ajustament layer
like saturation or vibrance for example
i found with the gpu on , a light slow refresh compared with gpu off
i have set cache levels 6 ,history 20
i guess are the defaul
well i add a saturation layer and move the saturation slide ,increase o decrease saturation
with Gpu Off , the changes are immedially , i mean i can see in real time the increase o decrease of saturation
with Gpu On it takes a few(very few) time more
again is normal ?
don't be angry , i'm going to buy cs5 and i'm unsecure ... the price make a big role
thanks

For what it's worth, I also see a timeout on the first [ Search Online ] click, after about half a minute delay. Second click turns up results immediately. This happens each time Lens Correction is started, even without restarting Photoshop, and in both 32 and 64 bit versions. Also note that I started with one profile listed by default (though from the wrong camera) for my 40D with 28-135 zoom.
I alsow noticed that I was seeing progress bar activity in the Lens Correction dialog while I was typing this (even though Lens Correction was NOT the active window) every time I hit the 'L' key. Strange.

Three questions about Java and Ftp

Hello, i've the following questions about Java and Ftp:
1- .netrc file is in $HOME directory but i can't access to this directory from java code. The following line producesan Exception (directory doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");
2- .netrc file must have the following permissions: -rw- --- --- but when i create the .netrc file the following permissions are on default: -rw- r-- r--, how can i change this permissions? (In java code, i can't use chmod.....)
3- Are there any way to pass parameters to a .netrc file? If i get to do this i needn't change the permissions because i can't modify or create/destroy this file.
Thanks in advanced!!!
Kike

1- .netrc file is in $HOME directory but i can't
access to this directory from java code. The
following line producesan Exception (directory
doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");$HOME would have to be replaced by a shell, I don't
think you can use it as part of a legal path.
Instead, use System.getProperty("user.home");
Ok, thanks
2- .netrc file must have the followingpermissions:
-rw- --- --- but when i create the .netrc file the
following permissions are on default: -rw- r--r--,
how can i change this permissions? (In java code,i
can't use chmod.....)Yes, you can: Runtime.exec("chmod ...");
I need to use estrictly the .netrc with -rw- --- --- permissions
Yes, i can use Runtime.exec ("chmod ..."); but i don't like very much this solution because is a slow solution, am i right?
3- Are there any way to pass parameters to a.netrc
file? If i get to do this i needn't change the
permissions because i can't modify orcreate/destroy
this file.I don't think so. Why do you need the .netrc file in
Java at all? Writing a GUI frontend?I want to use automatic ftp in a java program and FTP server, the files and path are not always the same, so i can:
- modify .netrc (for me is the complex option)
- destroy and create a new .netrc (is easier but i have permissions problem)
- use .netrc with parameters but i haven't found any help about it
Thanks for your prompt reply!!!!

Basic question about storage and safety in iMovie '11

A very basic question about storage and safety:
I want to keep a backup of my raw footage on my external hard drive prior to begin working on the movie in iMovie. I want to do this:
1. Upload the digital files from my camcorder to my Desktop *(as opposed to iMovie)*
2. Duplicate that footage/clips.
3. Put the duplicate clips/footage into a folder labeled with the name of that footage (like "Fun At the Dentist" or "Jimmy Learns How to Yodel").
4. Drag the folder with the footage/clips into my external hard drive into a pre-existing folder titled "Backups/duplicates of all of my raw footage/clips." This big granddaddy folder will house all of the child folders of different movies.
5 Then, open up iMovie '11 and import the raw footage/clips from my Desktop rather than from my camcorder.
6. Then I want to make a duplicate of my finished movie and put it in my external hard drive in a "Finished Movies" folder.
I know that the original raw unedited footage will always be in iMovies '11 but I want the original to also exist immediately accessible in my external hard drive.
QUESTION:
Is this viable? Is it wise? (I know it goes an extra unnecessary step, but aside from that.)
*Do you have any precautionary advice?* Should I do something in my iMovies '11 preferences? What?
In earlier years with iMovie '04 or '06 (cannot recall) I made many novice errors and ended up losing audio to my finished movie. I also lost footage.
This time around with iMovie '11 I don't to make such novice, ignorant errors.
Thanks so much for any comments to this question.

Yes I'm sure it will work great for you.
The iFrame format is something Apple has come up with. The reason for its existence is unknown to me so I can only speculate. But it seems to me that Apple "invented" this format in order to have devices such as Ipod/Ipad/Iphone/Ixxx create clips that are editable on consumer hardware such as already mentioned devices but also standard Mac computers, without the need for format conversion.
iMovie converts most input formats during import, which takes a lot of time, and this need for conversion often comes as a surprise to most people new to home video editing.
iFrame has a resolution of 960x540 which is long way from the common standards of 1920x1080 and 1280x720. If your end target is YouTube however, this may not be too bad though. However if you intend to go with YouTube HD, you may find iFrame footage to look wrong since they are effectively upscaled to a higher resolution.
Technically iFrame uses the H.264 algorithm, a smaller frame size (960x540) and a rather low compression scheme. This will result in large files, but the plus side is that the files are ready for editing without the need for any conversion and iMovie will natively edit the files.

Question about RAC and ASM

Hi,
We are thinking about build RAC using ASM for OEM database. It'll have two nodes, oracle 10g and Hitachi san with solaris ( or linux ). I've few questions about RAC and ASM.
1) Do I need to have ASM instance running on each node ? ( most likely yes... but want to make sure )
2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?
I'm a newbie to RAC and ASM..
Thanks,

2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?in 10g you can, in 11gr2 you cannot. and it might be better to seperate them because it will give you more flexibility with patching.
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?if you share your oracle_home you won't be able to do rolling updates. so i recommend to keep oracle_homes local.
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..follow the install guide for your respective version. for 10g you'd install clusterware first, then asm and database is last.
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?pretty much. you could stop your database and dump the raw devices or use asmcmd/asmftp but rman is definitely the best choice

Question about "synchronized" and "wait"

Hello, everyone!
I have seen a piece of code like this,
synchronized (lock)
//do operation 1
lock.wait();
//do operation 2
I think in the above piece of code, when a thead finished operation 1, it will release the lock and let other threads waiting for the lock have chance to run the same block of code. Am I correct?
If I am correct, I have a further question, a "synchronized" block means a set of operations that can not be interrupted, but when invoke "wait" method, the thread running in the "synchronized" block will be terminated (interrupted) by release the lock and other threads will have chance to enter the "synchronized" block. In short, the execution inside the "synchronized" block will be interrupted. So, I wonder whether the above piece of code is correct and conforms to the principle of "synchronized". And what is its real use?
Thanks in advance,
George

Thanks, pkwooster buddy!You're welcome
I just wondered whether "wait inside a synchronized
block" technology is thread safe. Please look at the
following example,wait and synchronized are thread safe.
public class Foo {
int mVal= 0;
public final Object mLock = ...;
public void doIt() {
synchronized(mLock) {
mVal = ...;
mLock.wait();
if (mVal == ...) {
// do something
} else {
// do something else
}If we have two threads, T1 and T2, enter the block in
their respective order, and T1 is woken up first, T2
may have tampered with T1's execution path because T2
changed mVal while T1 was asleep. So T2 manipulate
instance field mVal is a side-effect.when you do the wait() you give up the lock and the other threads get a chance to run. When you exit the wait() you get the new value of the myVal variable which may have been changed. This is exactly what you want. To make that not thread save you could do
int temp = myVal;
wait();
if(temp == ...)in this case the variable temp contains the old vale of myVal.
>
I think the most safest way is never wait inside a
synchronized block, but it is less efficient. What do
you think about the trick of wait inside a
synchronized block? I think you are very experienced
in thread field from your kind reply.
Thanks in advance,
Georgewait(), notify() and notifyAll() are very useful. You need them when you want threads to cooperate in an predictable manner. I recommend that you review the section on consumer and producer classes and wait and notify in the Threads Tutorial. It gives good examples. For a practical example of this you could also take a look at my Multithreaded Server Example. It implements a simple chat server that switches String messages. Look especially at the send(), doSend() and popMessage() methods in the StreamConnection class. These allow the receive thread of one user to send messages out using the send thread of another user. If you have questions about that example, please post the questions on that topic.
Hope this helps.

UNDO and TEMP usage by a schema

Hi,
How can I findout UNDO and TEMP space usage by a schema? do we have any tables for this?
If I want to get UNDO,TEMP space or any other resource used by a schema for 24 Hours period,can get this info.
Can you please suggest the procedure to know the high resource consumption application?
I am using Oracle 9.2.0.4 in SUN cluster environment.
Thanks very much in advance.I apreciate your help
Thanks
Thanks

Hi,
About UNDO, you can check the status of the undo segment currently used by active transactions.
select s.username, t.xidusn, t.ubafil, t.ubablk, t.used_ublk
from v$session s, v$transaction t
where s.saddr = t.ses_addr;About others user session's information, you can try this below:
select osuser,
       machine,
       username,
       segment_name,
       sa.sql_text
from   v$session s,
       v$transaction t,
       dba_rollback_segs r,
       v$sqlarea sa
where s.taddr = t.addr
and    t.xidusn = r.segment_id(+)
and    s.sql_address = sa.address(+)

HT201303 hi just got my new apple ipod touch i need to update my security information other wise it wont let me download apps it says to enter three questions about myself and i get to the third question and it wont let me enter the third question

hi just got my new apple ipod touch and to download apps it wants to add questions about myself for more sercurity information. i get up to question 3 and it wont let me select a question but it will let me write an answer so i just pressed done and then it says i cant carry on because ive mised out information when it wont let me do a question!

Welcome to the Apple community.
You might try to see if you can change your security questions. Start here, change your country if necessary and go to manage your account > Password and Security.
I'm able to do this, others say they need to input answers to their current security questions in order to make changes, I'm inclined to think its worth a try, you don't have anything to lose.
If that doesn't help you might try contacting Apple through Express Lane (select your country, navigate to iCloud help and enter the serial number of one of your devices)

Just installed iOS6, questions about "iMessage" and other things...

I've been a satisfied iOS4 user since I bought my iPhone4, but I was forced to install iOS6 tonight in order to download a "free" app. I found a few new icons on the screen along with about 200 percent more "Settings" I'd like to ask some questions about. I'm sure a few of these could be answered by doing a frantic and thorough search through weeks of posts but I'm a little short on time right now.
First, what exactly is iMessage? Looking at the page for it, I can't see any difference between it and regular text messages. The info page says its to avoid charges, but between my data plan and not being charged for text I don't see where theres any other benefit. The one person I text with the most recently asked me why I had not installed iMessage yet, and didn't have an answer when I asked him why I should. I guess he just wanted to see text replies in blue instead of green.
In a related bit, flipping through Settings>Messages>Send & Receive I find a "2 addresses" section, with my phone number in there as well as my email under "You can be reached by iMessage at:" and "Start new conversations from:". What good does it do iMessages to have my email address? Does the Mail app handle text as well as email addresses? That seems to be the only explanation, and also very odd to think I'd be trying to text through my Mail app.
Second, looking through the Settings>Mail I see now that I have an icloud email address as well as the mac.com address I've been desperately hanging on to for the past 10 years, and the me.com address they've been trying to force me into since those came out. (I was happy to see I could delete the me.com address from the phone. I wish I could delete it from the universe.)
I wasn't even aware there was a such thing as icloud.com addresses. When did this happen? What is it used for?
Third, under that icloud Setting I see a long list of apps with buttons labeled "Off" under it. What are those for? Under the Mac.com settings I see switches for "Mail" and "Notes", with Mail on and Notes off. The Notes app (which I haven't used since my old iPhone 3) still opens, regardless of this setting.
Fourth, I now have an item called "Facetime" under my Settings. It is off, but underneath it says "Your phone number and/or email address will be shared with people you call". I understand caller ID normally sends caller number info to the receiver, but why would someone need my email address if I call them?
Fifth, I now have a "Music" setting, at the bottom of which I see a "Home Sharing" item, which when clicked brings up my AppleID and asks me if I want to Sign Out or Cancel. What is Home Sharing? Its also at the bottom of the "Video" settings.
Sixth, now I have Twitter and Facebook settings? For what? I don't have accounts with either of those companies. So why have settings, especially since it asks me to create accounts and download apps for those companies right in the Settings?
Seventh, there is a camera icon on the unlock screen. Touching it causes the screen to bounce up about a quarter inch, almost but not quite revealing something behind it. I should probably just quit asking about this stuff already, but I'll take the bait - what is this now?
Finally, what is the Notification Center used for?
If I got a text under iOS4, it would put an alert on the Unlock screen. Scrolling through this huge list of things under the Notification settings I'm really blown away by all the apps set up to yell at me. I can see having an alert for a text message but Game Center? What the heck is that, and why is it set up to hit me with a "Badge App Icon" (whatever that is) when I get alerts from "Everyone". Similarly, the phone is set to alert me to something called a "Photostream Alert"? What is this? Why is there a Phone section for the Notification Center? So they can put a Notice on my screen to tell me the phone is ringing? Holy cow! The phone is set to send me alerts from the "Weather Widget". So if I miss the fact its raining there will be a message on my screen to let me know? Whats next - a buzzer to tell me I'm listening to music?
There's a lot more, like what would I need Passbook for when I have the actual movie tickets, gate boarding passes, coupons, etc in my hands, but we'll leave that for another time. Many thanks to all who can offer some answers to my questions above.

Hey Taantumus!
Here is an article that will provide some guidance on this question:

The next time you use an Apple feature or service that uses Apple ID, you'll be asked to sign in with your new Apple ID password.
Thanks for coming to the Apple Support Communities!
