What the result while a user thread holding pidlock to sleep?

I know pidlock is used to protect process create/exit/swap and so on. When a user kernel thread sleeps holding pidlock, the dispatcher doesn't work or system will hang? So what the real function of pidlock?
Thanks?

Hi, can't be sure out here, but it sounds that perhaps there may have been a hidden folder behind those other ones? Did you drag select?
If it isn't that then perhaps som Disk/OS maintenance is in order.

How to display additional fields in the results a 'search user'?

This may be a newb question but how can I display additional user attributes in the results of a user search in the admin console?
i.e. more than just the standard fields of: User ID, First Name, Last Name, Status, Enable, Disable, Unlock and Delete.
I would like to include some UDFs that I have defined for the create user form e.g. personnel number.
Thanks,
Bernie

Thats not gonna work for sure. Thats to include additional attributes in the search input parameters drop-down. There is another procedure to do that, but not very sure if it works or not because once I was decompiling the code and found that it doesn't have an implementation. You can anyway try it out, the worst would be that you would not be able to see the column headings, but try atleast:
And thats through the use of properties file. Open up ** and search for the following section-
*#global.request.users.selectedListDisplayFields=*
*#global.request.users.selectedListDisplayFields.lables=*
Remove the comments and update it to below-
global.request.users.selectedListDisplayFields=USR_UDF_EMPID
global.request.users.selectedListDisplayFields.lables=global.xmlmetadata.users.USR_UDF_EMPID
where USR_UDF_EMPID is the UDF and global.xmlmetadata.users.USR_UDF_EMPID is its associated translation.
Thanks

Error in the result while adding

Hi
This is a simple program which repeatedly adds a number once you define the step size of the number. Shift register is also being used. suppose if the no. is 9 and the step size is 1 then the result should be 10, but it is not so. what is wrong with the program?

It really depends on what you're doing. For a loop that is intended to run for a long time you do not want to have the loop steal all of the CPU processing time. Otherwise the user interface and the OS will become unresponsive. There are times, however, when you would not need to put in a delay, such as using a while loop to create a Functional Global Variable, a.k.a. Action Engine. Or, if the loop is intended to only run for a few iterations (and there's a guarantee that it will break out and not become an infinite loop).
These use cases have now better workarounds in newer LabVIEW versions.
Use an event structure for the UI loop. Only spin the loop if things change. Never do the same operations on the same inputs more than once unless you expect a different result every time.
FGVs no longer need loops at all, we can use globally initialized feedback nodes.
To guarantee that we don't create an infinite while loop, we use a FOR loop with the conditional terminal and wire a reasonable upper iteration limit to N.

Whats the functional difference between user IDs SAP* and DDIC?

Whats the functional difference between SAP* and DDIC? Can any one tell me please. I am new here. Thanks in advance.

Hi Farooq,
There are three user IDs in various SAP clients.
1. SAP* (Client 000 and 001)
SAP* denotes the default super user and has all administrative powers.
2. DDIC (Client 000 and 001)
DDIC user is responsible for the maintenance of the ABAP/4 Dictionary and the software logistics.
3. EarlyWatch (Client 066)
The EarlyWatch user has access only to monitoring and performance data.
Please check this link for more information on data dictionary objects.

IPhone3G, whats the result?

Hi..
I hope till now many of you have purchased iPhone3G. I want to know how was the experience of purchasing it.
1)Did you find any difference between iPhone and iPhone3G?
2)Is the speaker having more volume?
3)Does wireless and 3G eats less battery than the previous iPhone's internet?
4)Is the iPhone3G slow or hangs?
5)Overall how did you find iPhone3G?
Thank You!

*1)Did you find any difference between iPhone and iPhone3G?*
iPhone 3G screen has a slight yellow tint
iPhone 3G feels nicer in my hand
iPhone 3G connectivity on WiFi is slower than old WiFi waiting to find out if more people are experiencing the same problem
*2)Is the speaker having more volume?*
Yes its slightly louder
*3)Does wireless and 3G eats less battery than the previous iPhone's internet?*
This is tottaly subjective but it "seems" to me that 3G EATS up battery about the same or slightly more than the old iPhone.
4) Is the iPhone3G slow or hangs?
Without question the iphone3G is slower and hangs up considerably more than the old iphone.
Now I don't know if it’s because of the 2.0 update, or the new apps store, or the phone components where not the same quality as the old iPhone. I really think it has to do with the apps. So I’m going to uninstall all of them and give it another shot.
5)Overall how did you find iPhone3G?
Overall I love the 3G speeds over edge. So to me thats the biggest part.
The constant crashing is a MAJOR problem. In a typical hour period the iphone 3G is either un response or an app crashes about 3 - 8 times.
Certain features eg clicking on the SMS button was much faster than it is now.
If you don’t care about 3G speeds stick with your old iphone, until apple fixes the many problems.

Add WHERE criterias in addition to what the user enters on search page

Hi,
This may be a simple problem, but I have not been able to solve it.....Is there a way for me to code another search criteria in addition to what the user enters?
I'm trying to create a simple search page. Basically, user logs on, i get his acoount number and save it in a variable. Then whatever the user's search criterias are , I want to add "AND ACCOUNT = ???."
I've tried:
In the processRequest, retrieve his account number using a VO, stored account number in variavle x and then call a initQuery(x) for the VO to get only the rows that he should be able to see. Problem A: I get 'SQLStmtException' when I test the page by trying to do a Simple Search. So to fix that, in the VOImpl, I added these two calls -- setWhereClauseParams(null); setWhereClause(null); -- after the executeQuery(). After I did this, ran into Problem B: the user could search any record that wasn't associated with his account.
I also tried to dynamically create the vo using createViewObjectFromQueryStmt("Select * from table where account = " + x) but was not successful. The page didn't render and I received a ClassCastException similar to this thread -- Re: How to Create OAViewObject programatically
I'm new to OAF and would appreciate any pointers on how to implement this.
Thanks,
LL

Hi,
I assume that you haven't tried the following steps..if you have and still get an error, give us the SQL statement error that is coming up. If I misunderstood your requirement, could you elaborate.
I assume that when the user logs in you get the account number automatically.
You could define the VO to have the following where condition 'WHERE ACCOUNT=:1'.
Then you set the account id from the user using setWhereClauseParams(0,accountid) and call executeQuery. This would limit the result to that user.
This will work in addition to any other search fields that might have been used in the query.
For e.g with just the account id the sql that will be fired is
Select attribute1, attribute2....from Tablexxx where account = :1
Any other user search criteria given in the page will result in a ssql query like the following
select * from (Select attribute1, attribute2 ...from Tablexx where accoount = :1) where newattribute like `%xx`
Hope this helps. Let us know if you still have issues.
Thank you,
Arun

HT2638 Hi, My Iphoto (on Mavericks) shows me a thumbnail but actually it is another photo whan you open it up...any idea what the problem could be? big thanks!

This has happened since my snow leopard update to be fair. I continuously mess up all of my "events" with photoes that shoul now be there due to this mistake.
Anyone know something about it?
Big thanks in advance

given the time this problem has existed hard to say what the results will be but Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your thumbnails - this may take several tries

How to solve the issue "CUV check user equivalence failed" ?

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 VMs (rac1 and rac2) whose OS are Oracle Linux 5.6 in VMPlayer according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
In order to install Grid Infrastructure, we need to run Cluster Utility Verification (CUV) at first by running the cammand below:
[ora11g@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose
Its output:
Performing pre-checks for cluster services setup
Check: User equivalence for user “ora11g”
Node Comment
rac1 failed
rac2 failed
Result: PRVF-4007 : User equivalence check failed for user “ora11g”
ERROR:
User equivalence unavailable on all the specified nodes
Verification cannot proceed
Pre-check for cluster services setup was unsuccessful on all the nodes.
As you see above, check user equivalence failed. I have run the 4 commands to fix this error as below:
[ora11g@rac1 /]$ ssh-keygen
Its output:
Generating public/private rsa key pair.
Enter file in which to save the key (/home/grid/.ssh/id_rsa):

Warning: Permanently added ‘rac1-priv,192.168.137.35′ (RSA) to the list of known hosts.

After run the 4 commands above, I run the command below again:
[ora11g@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose
Its output is the same:
PRVF-4007 : User equivalence check failed for user “ora11g”
ERROR:
User equivalence unavailable on all the specified nodes
Verification cannot proceed
I think the problem is "Broken pipe" and ssh cannot write authorized_keys to the machines.
My question is:
Do any folk understand how to solve the issue CUV "check user equivalence failed" for 2 VMs ?
Thanks.

Folks,
Hello. Thanks a lot for replying.
I have installed Grid Infrastructure a few times. Each time, on step 7 of 9, the installer fixes and checks 2 machines correctly. The entire installation has 3 parts as below:
1) Install Grid Infrastructure for a Cluster
2) Execute Root Scripts for Install Grid Infrastructure for a Cluster (script is root.sh)
3) Configure Oracle Grid Infrastructure for a Cluster that includes NCA, ASMCA, PICA and CVU.
Each time, on step 8 of 9, the Installer installs Grid Infrastructure for a Cluster successfully that includes "Prepare, Copy files, Link binaries, Setup files and Perform remote operations".
But when the Installer get to part 3 CVU, it fails and then the Database cannot be installed.
Deinstall Grid is a very complicated process to do. Because of this reason, we need to run CVU at first to make sure everything is correct for 2 machines before install Grid.
Even we ignore "user equivalence (ssh)", we don't know whether other items can be passed or not because CVU cannot proceed to check the machines.
My question is:
How to have the script "runcluvfy.sh" continue to check the machines while confronting "user equivalence failed" ?

Creating AppModule in a background user thread (NPE)

Hello!

We want the thread creates an application module, fires some methods, releases the module and exit.

Please, anybody have access to sources, what you can say about this trace or do you have another ideas how to launch module from user thread?
Thanks in advance!
Ilya.

Repost.
Now I am trying to solve this issue by investigating, why module is running without errors if launched from console. In this case ApplicationPoolImpl.createSessionCookie is also fired, but don't try to obtain HttpSession from web container. When module is launched from background thread the pool ans session factory trying to do it (and error in EvermindHttpServletRequest.java occurs because there is no any requests).

My Apple TV will not update to the latest software, dose anyone know what the problem is, I've reset, tried to do it wirelessly as well as while connected via Ethernet cable.. Both have resulted in the same message!!

My Apple TV will not update to the latest software, dose anyone know what the problem is, I've reset, tried to do it wirelessly as well as while connected via Ethernet cable.. Both have resulted in the same message!! Update unsuccessful, current software version is 5.1 (5201) . I've rented a movie recently and does not appear in my movie list, but I have been charged for this movie, can someone help me out with these issues.

If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
Connect the micro USB cable to the Apple TV and to your computer.
Reconnect the power cable (only for Apple TV 3)
Open iTunes.
Select your Apple TV in the Source list, and then click Restore.
If when you choose restore you get a message that the device cannot be found, download the file below
Apple TV Software Restore 5.1.1 (2nd generation)
Apple TV Software Restore 5.1.1 (3rd generation)
Then hold down the option key while choosing restore and select the downloaded file when prompted.

only alternative you are left with is to implement it

multiple inheritance ).That's a bad advice. You should only extend thread if you actually want to change the behaviour, or extend the functionallity of the thread class. You should not extend the thread class just because it's convinient.
