How can I find out which tables are having DDL locks?

I can see related information by querying DBA_DDL_LOCKS view, but it doesn't give me the information which tables are having DDL locks.
Is there a way I can find out which tables are having DDL locks?
Thanks!

Here's a long script written back in 2001. Still works:
BREAK on sid on serial# on username
COL sid        for 9999
COL serial#    for 99999
COL username   for a20
COL type       for a20    trunc
COL lmode      for a5     trunc
COL lrequest   for a4     trunc
COL detail     for a75    trunc

How to find out what is the lock key for the computer

How to find out what is the lock key for the computer?

You don't.
If you forgot or lost the password, all you can practically do is reset it.
The manner in which you do so depends on what version of OS X you are running. The older versions utilize the reset password utility on your recovery/re-installation disk/drive.
On Lion, you use the following technique to reset the Administrators password:
Boot to your Lion Recovery Partition, by holding down the Option key while starting, and then selecting the Recovery HD as the boot choice.
Once booted, at the top of the screen is a menu ..., select Utilities / Terminal from the menu bar.
In the Terminal window, type “resetpassword” (without the quotes) and press return. A “Reset Password” window will open. Select your boot volume (your SSD drive) if it is not already selected. Select your administrators username from the menu labeled “Select the user account” if it is not already selected. Follow the prompts to reset the password. Restart the computer from the apple menu.

How do I find out what applications are running in the background

I have a 2008 iMac with 2GB memory. How do I find out what programs are running in the background? I am going to buy a new iMac before the end of the year to replace this one. When I looked at Activity Monitor it shows 1.8Gb used but doesn't tell all the programs running.

open activity monitor [if it doesnt launch click winders>Activity Monitor]. then it'll show all proceses

11.1.2- Need to find out what reports are being executed by a user

Hi,
We have financial reports executed from workspace.In essbase session , only the user id is displayed and the Request type- mdxreport is displayed. We also tried searching the log for Financial report didnt find anything relevant.
Is there a way to find out what reports are being executed by the user.
Thanks in advance.
Regards,
Saumya

STAT will give you the information for a limited period of time and is limited to the server which you are logged onto yourself. Beyond 24 hours it is of even less use even if you change the selection screen values.
If you want it for a period way back into the past, then you need to use ST03N.
There are at least 2 dependencies and 1 confusion:
1 dependency) The length of period is determined by the size (length) of the file. You can change this in ST03N (default 50MB) via the menu settings.
2 dependency) The stat collector jobs need to be scheduled to write the information to ST03N (once per hour is a legal requirement in some non-banana republic countries).
1 confusion) There is an obscure function which converts a report submit to a transaction name (there is not much difference anyway) and an even more obsure one which filters what ST03N will record and therefore whether you can read it. You can (un)filter these things away if you search the SAP Marketplace for the term "MONI".
What is of particular value from this control is that you can even detect a submission of an abap which only existed temporarily.
Also note that having this information is potentially very powerfull with respect to the users (some of them are human too), so you should expose and use it responsibly.
You should also ensure that only responsible users / auditors have access to S_TOOLS_EX.

How do i find out what devices are authorised on my apple ID?

I have just bought a new iMac and want to get all my itunes library etc on it. However, apparently i have reached my limit of 5 authorisations, which is entirely possible as I have had a number of iphones, Macair and ipads, some of which I either no longer own or are no longer functioning. How do I find out what devices are authorised and then deauthorise any that I don't use any more - given that they may not even work!

Welcome to the Apple Community.
You can't de-authorise just the computers you no longer have access to.
Your only option is to de-authorise all your computers and then re-authorise those you wish to be authorised. You can do this by logging into your account settings in iTunes on your computer (Store > View My ID) and selecting the option to de-authorise all.
Please note however, you are only permitted to do this once in each 12 month period, therefore you would be better de-authorising your computers before you lose access to them. you can do this from the 'Store' menu in iTunes.

How do I find out what features are not useful in my Classifier?

How do I find out what features are not useful in my Classifier? I am trying to trim down the number of features to speed up the training of my data, I have about 3700 features. I have found the Filter Based Feature Selection Module and have not been successful
in using it. I have looked through all the examples and have not been able to find any examples using the module. Will the Filter Based Feature Selection Module help me to trim features. If so how do I use it?

One way to do this would be is to use a random forest classifier. Feature/variable importance can be obtained relatively easily with random forests.
Here is how you may do it in R.
> install.packages('randomForest') #install randomForest package in R if it is not already there
> library(randomForest) # reference the library
> data(mtcars) # load motor cars data that ships with
#train a random forest
> mtcars.rf <- randomForest(mpg ~ ., data=mtcars, ntree=1000,keep.forest=FALSE, importance=TRUE)
> importance(mtcars.rf)
> importance(mtcars.rf)
#You will see an output like below
%IncMSE IncNodePurity
cyl 16.168645 169.96741
disp 18.672188 260.08722
hp 17.584375 184.95007

gear 4.619161 21.55450
carb 8.577037 28.46715
# or plot the importance as follows
> varImpPlot(mtcars.rf)
What this tells you is how important predictors/features/variables like horsepower(hp), weight(wt), no. of cylinders (cyl) is in predicting miles per gallon (mpg).
If you are wondering how the data looks like. Try this
head(mtcars) # gives first few lines of the data set.
mpg cyl disp  hp drat   wt ...

Datsun 710    22.8   4  108  93 3.85 2.32 ...
. Try this
Here is a few useful resources:

Oh, then you can't unless you know someone with a Mac you could use for a moment or 2. (Like at the Apple Store)

How can I find out what apps are on my step daughters phone without the phone? She is on my phone plan but does not live with me and I am concerned about the apps she may be using.

baniville108,
Thank you for reaching out to us. We certainly know the importance of being able to know what options are available with your device. With apps on devices, thoses are specific to the phone itself, so there is no open forum to view what apps are downloaded. The only option would be to physically review from the phone, or if you have the same Apple ID you can log into it and view from there. Please let us know if you need anymore assistance.
Thank you,

Please tell me SQL to see, what tables are locked by which user

could you please tell me the query
so that I can see, what tables are locked by which user in a databse
Thanks

The only way you can ensure that only one transaction touches the data at any one time is to use a select .. for update nowait statement to select the rows to be updated.
Try this::
Where I select the data i want to update in a cursor Incase the row is locked due to any reason it will throw me an error as shown below;
SQL>DECLARE
2   cursor c
3   is
4   select * from emp
5   where empno = 10
6   for update nowait;
7 BEGIN
8
9   for rec in c
10    Loop
11     update emp set ename ='J' where empno = 10;
12    End Loop;
13
14 DBMS_OUTPUT.PUT_LINE('Record Updated');
15
16 EXCEPTION
17
18 WHEN OTHERS THEN
19
20 DBMS_OUTPUT.PUT_LINE(sqlcode || sqlerrm);
21
22 END ;
