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.

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 histograms and indexes

I read that if a histogram is generated for a column and that column has an index then if the where clause contains a value that has a high cardinality the CBO will skip using the index. The article was with reference to the benefits of histograms.
My question is: Why would the CBO skip using the index? Why not use it anyways? Is it because there is a cost associated with loading and using the index itself?
Would appreciate some clarification on this, thanks!!!

First, the article in question doesn't say to create histograms on columns with high cardinality values. A primary key column is going to be the ultimate in high cardinality columns (each value is unique after all) but it's rarely appropriate to create a histogram on that column. It does say that that histograms are generally useful when the data in a particular column is highly skewed-- that is, different values occur at wildly different rates.
If you have a table of orders with an ORDER_STATUS column, for example, 95% of your orders may be CLOSED, 3% may be SHIPPING, and 1.9% may be IN PROCESS and 0.1% may be CANCELLED. Without a histogram, Oracle would take a look at that column and see that there were 4 distinct values, so it would assume an equal distribution across the statuses. Which would cause it to favor a full scan on the table even if you were looking just for the CANCELLED orders. With a histogram, the optimizer would favor an index on ORDER_STATUS for the cancelled query while still favoring a table scan if you're looking for closed orders.
Gathering unnecessary histograms will make statistics collection take longer, which can cause issues with SLAs. It can also force you to gather statistics more frequently/ cause statistics to get out of date more quickly if you have monotonically increasing values in a column. If you have a CREATE_DATE column, for example, and gather a histogram, values that are greater than the max value at the time the histogram was gathered might be incorrectly estimated to be too infrequent, which can cause problems. If Oracle thinks that 1/6th of the rows are from Jan, 1/6 from Feb, etc. through June and you start looking for values from July because you haven't gathered statistics in a month, the CBO's estimates are going to be off. Unnecessary histograms also cause Oracle to spend more time parsing queries, potentially with no better results. And it can make troubleshooting a bit more difficult because, depending on the version and various optimizer settings, there may be multiple query plans for the same statement or different query plans depending on the particular bind variable that is first passed in.

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 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

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

Trying to create a Histogram type/object for aggregate functions

Hi,
I am trying to create an aggregate function that will return a histogram
type.
It doesn't have to be an object that is returned, I don't mind returning
a string but I would like to keep the associative array (or something
else indexed by varchar2) as a static variable between iterations.
I started out with the SecondMax example in
http://www.csis.gvsu.edu/GeneralInfo/Oracle/appdev.920/a96595/dci11agg.htm#1004821
But even seems that even a simpler aggregate function like one strCat
below (which works) has problems because I get multiple permutations for
every combination. The natural way to solve this would be to create an
associative array as a static variable as part of the Histogram (see
code below). However, apparently Oracle refuses to accept associate
arrays in this context (PLS-00355 use of pl/sql table not allowed in
this context).
If there is no easy way to do the histogram quickly can we at least get
something like strCat to work in a specific order with a "partition by
... order by clause"? It seems that even with "PARALLEL_ENABLE"
commented out strCat still calls merge for function calls like:
select hr,qtr, count(tzrwy) rwys,
noam.strCat(cnt) rwycnt,
noam.strCat(tzrwy) config,
sum(cnt) cnt, min(minscore) minscore, max(maxscore) maxscore from
ordrwys group by hr,qtr
Not only does this create duplicate entries in the query result like
"A,B,C" and "A,C,B" it seems that the order in rwycnt and config are not
always the same so a user can not match the results based on their
order.
The difference between my functions and functions like sum and the
secondMax demonstrated in the documentation is that secondMax does not
care about the order in which it gets its arguments and does not need to
maintain an ordered set in order to return the correct results. A good
example of a built in oracle function that does care about all its
arguments and probably has to maintain a similar data structure to the
one I want is the PERCTILE_DISC function. If you can find the code for
that function (or something like it) and forward a reference to me that
in itself would be very helpful.
Thanks,

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!

Striving is without limit!

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!

Some questions about a Time Capsule

Hi!!
I just have a few questions about a Time Capsule, but first let me explain the backgroud to my questions.
I live in a 2 floor house(including a basement) and my bedroom is downstairs. My parents currently have a desktop PC connected to our wireless router and our printer. Me and my step-father both have 13 inch MacBook Pros, and he uses the Mac like a basic computer, so the equipment connected to our PC is good for him. I, on the other hand, use my Mac, iPad and iPhone to their fullest potential. I am a SUPER MEGA NERD when it comes to computers, so I plan on making my bedroom an amazing office at the same time. So I want an AirPrint Enabled printer in my bedroom (Under 100$$) along with a Time Capsule to back up my information, because everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
If you don't understand what I'm trying to ask (Even though I feel like it's self-explanatory)
ONE question about the PRINTER: Do any of you have any recommendations for an AirPrint Enabled printer under 100$? Even under-150$ would be okay.
THANKS FOR ANY HELP!!!!

everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
Don't just depend on TM.. use a disk image type utility.. either one of the Mac tools, SuperDuper, CCC, Chronosync or even a linux boot cd (if you have a cd/dvd drive still or via usb can boot) a great tool is Clonezilla.. it will do basically any computer, Mac, Linux, Windows.. and since it boots into its own OS can restore a computer in a flash. Then you can add the incremental changes from TM.
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
Actually I am surprised you get good wireless as usually directly above or below a router is often the worst spot. Time Capsule cannot extend the wireless of any other router than Apple.. it is a special system and only Apple can join the club. It has bad effect though, if you set the TC to extend wireless it turns off ethernet ports.. which is hugely dumb.
The best arrangement is ethernet to the upstairs.. or EOP adapters. If not then a wireless router that matches the existing unit will generally be better than mixing apple and non-apple.
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
You create a new wireless network by selecting manually the wireless channel and use different wireless name, ssid and security. There are 3 available channels on 2.4ghz.. your existing router will use one or two.. depending on if the setting is 20mhz or 40mhz.. so you need to manually set everything and not use auto.
TC is slow on 2.4ghz cf 5ghz and there are many more channels at 5ghz but not everything can use it.. iphone for instance is 2.4ghz only . whereas ipad can use 5ghz.. most full computers now can use 5ghz.
Buy a wireless network printer. Or alternatively an ethernet network would be also ok but now are more expensive than wireless ones. Network printers are not much more than straight USB and work much better.
I do not use airprint so have nothing to offer.. find the best HP model in your budget.. but others may have had more experience.. I use ethernet connected b/w laser business type HP.. they work great.. but airprint is too recent an innovation for me.

Question about download file in OAS4

Question about download file in OAS4:
I use Oracle Application Server 4.0.7 on my Windows NT 4.0 SP6;
I use PL/Sql Cartridge developer a document system; It's use the
upload/download in PL/Sql Cartridge;
I read the document , the Upload/download in Pl/Sql Base on the
Oracle Application Server's Content Service. the Problem is when I
download a document, If I upload a Html or MsWord file, It will store in a LongRaw column, when me download ; It's tell me can't
find a application to open this file; I will select a application
from list to open the download file;
As normal, It will open MsWord Automatic when download a "doc" file ; also It will open a new window of Browser to view a Html file;
I check the download process on client Browser; when download
file, The content-type always return "application/octet-stream";
Also the download File will lost the postfix of the file,
So Browser don't open the File Automatic;
I think If I set the correct Content-Type , Browser can know how open the file; So I use owa_content.set_content_type procedure
set the Doc file to "application/msword" , but the WEb Server always
return "application/octet-stream";
I didn't know how to do this problem, Plese help me.

I have a Tecra M2 and rely on your email update to ensure I have the latest drivers on my machine.
When I received a Toshiba support email on 14 April 2005 giving reference to a QFE from Microsoft I assumed it would be necessary for my Tecra.
I was very confused when I found that this QFE and subsequent ones posted on the 16 April 2005 relate to Pre SP2 critical updates no9t required if one has already taken earlier advice of updating to Service Pack, at the very least your narrative should make mention of this. I find it very difficult to believe that your updates are two+ years out of date.

No reason to be embarassed. You are not alone.
You will need an external drive. If you have a Time Machine drive without enough disk space you can create the clone there however it's advised that you keep your Time Machine and clone on separate drives. If the drive dies you loose both types of backup.
Download and install the clone software. Everyone has their favorite. These are the two most common applications used. I prefer SuperDuper because of it's simplicity in setting up. It's also free for the first clone where with CCC you have to give a Credit Card then cancel if you do not want to keep.
SuperDuper! http://www.shirt-pocket.com/

Select your drive in the To popup. Click on Copy Now. That's it.
Yes, it really is that simple....
