Question about wait type NETWORK_IO

From the articles below, we know the NETWORK_IO composed by network transmission + Client application dealing with the rows.
That's suppose the NETWORK_IO is 100 seconds, so my question is how many seconds spent for network transmission , and how many seconds spent for Client application ?
As If I don't know the time spent for the two components respectively, I wouldn't know if it is a network issue Or Client application issue.

Hi,
Wait stats are cumulative and the 100 ms would include total waiting time it wont be possible to segregate the time. Its cumulative of time when result set was sent to client and when client gave acknowledgement that result set is consumed

A question about item "type and release" of source system creation

Hello expert,
I have a question about item "type and release" of source system creation.
As we know,when we create a web servie source system,there will display a pop-up which includes three items as "logical system","source system"and "type and release".
About the item "type and release",when we push "F4" button,there will be three default selections as below:
"ORA 115     Oracle Applications 11i
TLF 205     Tealeaf 2.05B
XPD 020     SAP xPD".
Who can tell me when and how should I use the three selections.
And also I attempted to input the item by some optional letters except the default three selections and it seems that I can input it freely.
Thank you and Best Regards,
Maggie

Hello DMK,
Thank you very much for your answer.It is very helpful for me.
Can I ask you further about it?
I got that it is a semantic description item.
You said the default selections are set by our basis people.Would you like to tell me how should we creat a new value except the default ones for item "type and release"?Only by inputing the value in the item directly?But you see we canot see the new value item we created by ourself when we push "F4" button next time ,is that ok?Or do we have to ask basis people to define one new value item just like the default seletions before we use it.
Also if possible would you like to describe detail about "This becomes important when you are troubleshooting certain issues especially when RFC connection problems."
Thank you and Best Regards,
Maggie

Question about histogram types

Hi there,
I have question about HISTOGRAM column in ALL_TAB_COLUMNS.
There are 3 different histogram modes in all_tab-columns.:
NONE, FREQUENCY , and HEIGHT BALANCED .
Has anyone knows about these options in detail and how can I change between
these?
Thanks.

And Wolfgang Breitling's papers are always the best resources about histogram.

SQL*Net more data to client 14,022,144 3,758 0 17.7 Network
Edited by: orausern on Apr 15, 2010 5:07 AM

Your average wait on "more data to client" is very small.
The number of calls is large - but you don't have any real measure of its significance and meaning.
You need to look at Instances statistics:
SQL*Net roundtrips to/from clien         17,407,740        9,876.1          32.6
bytes sent via SQL*Net to client      4,429,719,421    2,513,152.0       8,303.4A round-trip consists of one 'sql net data to client' plus ALL the ' more data to client' that took place at the same time, so:
Compare your count of 'more data to client' with roundtrips - if it is a large multiple you can infer that on average each round trip is a large chunk of data that has to be sent as several packets, and you probably need to make your SDU larger. If you look at 'bytes sent via SQL net to client' compared to roundtrips, you get an idea of the size of the the "average" packet - hence an indication of the necessary size of the SDU.
There are also a couple of tcp network configuration parameters that may need setting. I never remember the exact names, but it's something like 'tcp_transmit_buf' and 'tcp_recv_buf'. This is the volume of data that the tcp layer can send before it needs an ACK from the far end. So, for example, if your SDU is 32K and your tcp buffer size was only 4KB, then Oracle would send one packet of 32KB, tcp would handle as 8 chunks of 4KB - with 8 tcp ACKs from the far end, and the (because tcp works in line packets of about 1400 bytes - each 4KB would go as 3 packets with an ACK expected on the third). So you need the tcp buffer sizes to be slightly larger than the SDU for best effect.
(If your procsses parameter is large, though, the total tcp buffer memory needed is processes * tcp buffer size).

Question about declaring type as interface

Hi
I am trying to get my head around declaring an object as the interface type (I think this is right correct me if I am wrong). Ok so I understand if I declare my object reference as the interface I will only get the methods of the interface defined in the objects class..? ie
List myList = new ArrayList();I think any method particular to ArrayList will not be there. But I dont actually understand wha is happening here, I have a ref to a List but the object is actually an ArrayList?
So if I passed ths list to a session object and got it out I could cast it back to the interface. I dont understand why or what is happening here.
I hope someone understands my question enough that they can help me out, this has been nugging me for a while.
Thanks

I am trying to get my head around declaring an object
as the interface type (I think this is right correct
me if I am wrong). Ok so I understand if I declare my
object reference as the interface I will only get the
methods of the interface defined in the objects
class..? ie
List myList = new ArrayList();I think any method particular to ArrayList will not
be there. If you use myList without casting, then, yes, only List's methods will be available, because all the compiler knows is that it's a reference to a List. It doesn't know that at runtime it will point to an ArrayList object.
You could cast myList to ArrayList to get ArrayList-specific things (if there are any), but a) if you're not careful, you can end up with a ClassCastException at runtime (you won't here, but in general you can) and b) if you're going to do that, you have to question why you declared it as a List in the first place. There are cases where casting is appropriate, but you have to be careful.
But I dont actually understand wha is
happening here, I have a ref to a List but the object
is actually an ArrayList?Yes.
So if I passed ths list to a session object and got
it out I could cast it back to the interface. I dont
understand why or what is happening here.You could cast it to anything that the object actually is, that is, any of its superclasses and superinterfaces. If it's an ArrayList, you could cast it to any of the following: ArrayList, AbstractList, AbstractCollection, Object, Serializable, Cloneable, Iterable, Collection, List, RandomAccess.

Question about storage type 902

Hello Everybody!
I´m implementing SAP WM and I have a doubt and is the next one:
When I do a material movement, system returns an error if the material is not create in the destiny storage type.
On the other hand, I create a purchase order and when I make the good entrance, the system stocks the material in the storage type 902 even the material is not create in this storage type.
Why is the reason for this? Is not necessary to create the materials in the standar storage type like 902?
Thank you very much for your help!

Hello Javier
You are right when it comes to goods receipt or goods issue. All the 9** series storage types are interim storage types which are fictitious. You only have to create 1 bin for each interim storage types. When you create the material master maintain the WM views only for the warehouse number and the other storage types that you use where all the bins are located. For storage types 902 the PO/inbound delivery number and for 916 outbound delivery number will be displayed as the bin numbers which are dynamic bins that gets deleted automatically once you complete the movements.
Thanks

Question about file type designations

Hi,
I use a program called Sound Studio to record meetings that I do. Lately, what's happening now when I download videos emailed by friends, the file extension says .mp4, but when I open them, Sound Studio opens up and I only hear the audio (because audio is all that program does). When I do the get info command, the instructions say open file with Sound Studio, rather than QuickTime.
Is there some kind of setting somewhere, either in Snow Leopard or in Safari, where I can set that all downloaded video files are to be opened by Quicktime?
Thanks.

change the default app in that popup from sound studio to anything you want to use like Quicktime player and click 'change all".

Technichal question about primative types

A float is 32-bits but not all are used for storing the number, does anybody know weather they have a set structure or/and in which order the bits are set out?
I am wondering weather it is possible to bitshift, or use other bit-wise operations for that matter.
Thanks in advance. Bamkin

IEEE 754 floating point numbers have the following bit-assignments -- bit 31 sign bit (s)
bit 31-24 exponent (e)
bit 23-00 mantissa (m) When the sign bit (s) is zero, the number is positive, otherwise it's negative. The exponent part
is biased, i.e. the 'real' exponent is interpreted as e-127, so the 'real' exponent has a range
[-127, 128]. If the exponent (e) equals zero, the mantissa (m) is adjusted to 'm<<1', otherwise
'm|800000' is used. The latter trick effectively adds one more bit of accuracy to the mantissa.
If the mantissa (m) equals zero and the exponent (e) equals 0xff, the number is considered
to be +/- infinity (depending on the sign bit).
kind regards,
Jos

Question about Page Builder behavior - how to get a "please wait message" ?

Hi all together,
I got a question about Portal Framework / Page Buider handling iView Integration.
We are working with a lot of App Integrator iViews and often the pages includes with app integrator are loading longer than the rest of the portal. So there is the idea to put in a "please wait while loading message" for the enduser.
I analysed the html code, the page builder is generating and foud out 3 diffrent approaches how the page buider is rendering the IFRAME with the integrated application configured with an app integrator iView.
My question is how can I influence this behavior to put a "please wait while loading message"?
Different types of iView integration in the client I have seen:
a) direct loading of the content in the IFRAME (<iframe id="" ... scr="/mysource">)
b) Filling the iframe with 'about:blank' and loading the content later by filling a form with JS
( <iframe id="" .... scr="about:blank">and after the iframe <form id="" action="mysource" ...>
c) Filling the iframe with a html file from the portal layout and loading the content later by filling a form with JS (similar to b)
( <iframe id=""" ....scr="/irj/portalapps/com.sap.test.mylayout/html/blank.html>
I checked that variant b) is getting generated when loading a page with different components on the side (not only the app integrator iview) and variant c) is generated when just one app integrator iView is positioned (no portal page).
Goal: To get the "please wait picture" I want to know how to get variant c) in cases of different elements on one page
So I would be able to put this picture on the HTML-Page in the Portal layout (blank.html)
Hope, someone with a deep portal / page builder know-how can help me out!
Another way: Does anybody knows another way how to put a "please wait message" while app integrator application is not loaded yet?
Thanks in Advance and kind regards,
Jens

Hi Jens,
there are several reasons why you don't get the loading animation:
Web Dynpro ABAP: https://service.sap.com/sap/support/notes/1432358 -> missing configuration
Wrong height size for iView: https://service.sap.com/sap/support/notes/1358494 -> alter configuration of the iFrame height (loading animation gets displayed, but is hidden)
FPN, BSP, BEx: https://service.sap.com/sap/support/notes/1290995 -> AI isn't showing the animation because of performance considerations. I guess that is your case. Depending on your portal version this is a simple service configuration or involves some customization.

Tobias

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.

I am an HP employee.

My HP, purchased in June 2012, died on Saturday. I was working in recently installed Photoshop, walked away from my computer to answer the phone and when I came back the screen was blank.

I'm not happy with HP. Any suggestions?

A lot of questions about my MacBook Air

I am really new to re-using Apple computers.The last time I used an Apple computer was back in 1987 when the school and my family had Apple IIGS computers. I have been using PC's which reqiure Microsoft. I a lot of have questions (10 questions) about my MacBook Air and I hope you good people can and will help me.
Product: MacBook Air
Operating System: Mac OS X Version 10.7.4
1) I Downloaded MacKeeper because I was fooled. I had a bad feeling just before I Downloaded it and I should have listened to my heart. However, I didn't buy it or fully Install it. It was like a test run and then they wanted me to pay almost $100 for it. Thankfully, I didn't because I read it is Malware. I spoke with an Apple Tech at Apple Care and he helped me get rid of it (or so we think). I don't see it anymore on my computer. I read it can slow down your computer. How can you tell if it's really off of the computer?
2) When I open "Finder" and I see that there are people Sharing my computer with me. I went into AirDrop and it reads, "Other people can see your Mac as (my name) MacBook Air when their computer is nearby." I bought a HotSpot and while it's turned on and I selected it as my WI-FI connection I thought it would get rid of these people, protect what I type, me, my items, computer, etc. But it didn't.
I didn't know that I have to buy a exteral CD and/or DVD Player in order to connect to the brand new Modem and Router in one by NetGear. I am so used to PCs and the CD/DVD Players being built inside.
The people at Apple Store told me that there is an internal modem inside, but I don't know how to find it and what to do then. Should I use a Firewall?, An AntiVirus, AntiMalware, AntiSpyware, etc. Apple Care tech told me I don't need to get an AntiVirus.
3) Is there a new kind of Wireless Modem and Router that doesn't require a CD-ROM?
4) When I travel or fly and I am not close to home I was told by Best Buy and Sprint that I had to buy a mobile HotSpot to use the computer (WI-FI) safely. As I typed, I have one. But it's pretty expensive and only gives me 1 hour and 15 minutes per day to Stream. What can I do to use this computer safely Online when I am out of range from a Modem and Router? What do people do when they travel on airplanes?
5) This compter won't let me use "Raid." I think you have to have a newer version. I hard about Raid on the radio from Leo (can't recall his last name) who's a Tech expert.
6) Should I buy a ZipDrive? Apple Store Tech told me that I didn't need a ZipDrive. I just remember the episode of HBO's "Sex and The City" when Carrie looses everything because her copy crashed. Now, of course, I know that's a fictional show, but with PC's and Microsoft I have lost everything when it crashed, frooze up, etc. I know there's iClouds. I heard about Carbonite, but I have read the Pros and Cons about it. Mostly they are Cons about it. I just don't want to do anything wrong and mess up this computer.
7) Should I buy a new Printer/Copier/Scanner because mine is an HP. It's not new, but it works. I even have a CD-ROM for Macs. What about the new product called, "Neat"?
8) Is there a special product that I should buy to do Online Banking and/or other important stuff?
9) I saw and read about iWork in the Apps Store and it sounds cool. I still have alot of friends and colleagues who still use Microsoft. Is iWork good to use? Should I Download it from the Apple Apps Store or can a buy it at Apple? Is there another Word Processing Program that is great and user friendly and will work with Macs and PCs?
10) Should I Update the OS with OS X Mountian Lion Pro from the Apple Apps Store or buy it at Apple Store?
In advance, I wish to thank you in this Apple Support Communites for your help. Have a safe and happy holiday weekend!

1) Here are instructions for removing MacKeeper. Since it mostly consists of manually looking for folders and specific files, if you follow the instructions you either fail to find what you are told to find (because your AppleCare guide gave you complete instructions which you followed) or you'll find some additional files that need to be replaced.
2 & 3) I assume you are looking at the sidebar of a Finder window and seeing Shared and computers under it. Those are computers that you can potentionally share. To do so you'd need an account on their computer and a password. They are not sharing your computer.
AirDrop allows you to create an adhoc network for filesharing and it only functions when you have selected the AirDop item in the SideBar. Actually doing that merely announces to computers in the same network node that your computer is available for a file to be sent to. Even then you have to explicitly allow the file to be downloaded to your computer. Similarly you'd be able to see other computers with AirDrop selected and be able to send them a file - which they'd have to accept.
The only reason your NetGear Router comes with a CD is to install and run their 'easy' step by step configuration program. It can also be done manually with a browser. Read the manual to find the IP address you must enter to access the router's configuration menu. Apple's WiFi routers don't require a CD to install the software because the configuration software is already on your computer.
I do have my firewall turned on. AntiVirus software isn't a bad idea - I use Sophos having tested it for a review for our local User Group and I found I liked it better than ClamAVx which is what I'd been using before. Both are free.
4) I think you were scammed by Sprint and BestBuy. I use hotel, coffee shop, and restaurant WiFi spots and have for years. However, because they can be unsecured, I do not shop online or bank when I'm using them. I also use 1Password and don't reuse passwords so even if a sniffer should grab an account and password that's all it would get - one account.
5) Raid doesn't really make sense with a MacBook Air - a RAID involves 2 or more disks being used as if they were one.
6) Zip drive? No. External hard drive - yes. It isn't a question of if a computer's hard drive will malfunction, it is when. OWC has a nice selection of external drives and the Mac has a built in backup system called TimeMachine. Due to the way TimeMachine works, I've found that your TimeMachine drive should be at least twice as large - and preferably 3-4 times as large as the data you are backing up.
7) if your printer works and it has Mountain Lion drivers, why replace it?
8) Online banking is done with a browser - Use Safari or FireFox
9) If trading files with Windows users is important Mac: Office is your best bet. If not, iWork, Mac:Office, or LibreOffice are all good possibilities.
10) you can only buy Mt Lion via the App Store.

Some questions about configuration in MAX.

Hello,everyone!
I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
My question as following:
1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
If I select stepper,though motor can work but I can't test encoder in MAX.
2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
My English is poor,Pls pardon me!I come from China.
Thank you for your help!

Hi,Jochen,
Thank you for your kindly help!
The manufacturer of the drive and motor that I am using now is Japan SANYO DENKI,drive type is RS1A01AA,motor type is R2AA06020FXP00.
And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
1,Motor can't run.
2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
Except for the two points mentioned above,"Following Error" is occured frequently,I don't know why.
I am still not clear why I must set the motor type be stepper in MAX .
And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
I am verry sorry I have too many questions!
I am very appreciate for your kingly help!Thanks again!
