Posiible to limit query time for any one query
Hi,
Using 11.2.0.3
We have a third-party web-based reporting tool where sql queries are initiated on the database- sometimes the user kills the browser session and query still runs on the database.
Is it possible ata dtabase level to set max time any one query can run e.g. no query over n hours. This would help kill such queries.
Also is it possible to cap individual queries to say one query can never use more than n% of cpu, ram available?
Thanks

ThanksIf you have Enterprise Edition licences, this is straightforward with the Resource Manager: set a threshold for MAX_EST_EXEC_TIME and all queries that might exceed this will be blocked. You also have CPU limits available.

How do I use Airport Extreme to limit internet time for my kids? His computer is hardwired to the modem.
You can set up daily time limits for each computer that connects using wireless, but it is not possible to do this when a computer is connecting directly using a wired Ethernet connection.
Open Macintosh HD > Applications > Utilities > AirPort Utility on your Mac and click Manual Setup
Click the Access Control tab below the icons
Select Timed Access
For more details on this, click the Help menu at the top of the screen and enter the following phrase into the search box:
Controlling access to your wireless network
A more sophisticated approach would be to use a service provided by OpenDNS. From your computer, this would allow you to monitor web sites visited, and block any unsuitable sites. More info is here:

Spool printing takes a long time for just one user
Hello,
Could someone please guide on what could be the reason that spool printing takes a long time for just one user ?
I've monitored all the spool processes through SM50, and I've found that a very long time elapses before the printing job appears in one of the four spool processes.
Thanks in advance.
RedaHi,
very long time elapses before the printing job appears in one of the four spool processes.
can u check the trace file(Red color error) of that spool process. Also can u see if there are any system logs in SM21 related to that spool request.
Also see how many pages the user is giving print @ 1 shot. Suppose if the printer to whcih the user is giving print is a network printer, see the network response time.
Have u tried to ask the same user to give print to some other printer. Also have u asked some other user to print to that problematic printer. Check the responses under this scenario also.

My ipod won't let me connect to wi-fi, won't let me restore or reset it, and it keeps telling me i knew a passcode for any one and I never set a password up. How do I fix this? Says try again in 6180146 min. my passcode setting is off, but restrictions are on. Very frustrated. please help
Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.

For how to restore:

To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.

Ideal execution time for any program
Hi,
Is there any method to determine the ideal execution time for a program ?
Or else how to determine that ?
I just wanted the max. time that a program can take so that the performance would not be hampered.
Thanks,
Binay.did you ask for the 'ideal execution time' or 'how to measure execution times'?
The second question was answered in one of your other questions.
Optimization:
Do SQL Trace, go to Summary by SQL statement, check 10 Top contributions (time = duration).
Try to optimize them, note minimal time per record, if larger than 10.000 microsecodns, then you should index usage.
Do SE30, go to hit list, sort by net time, again address 10 Top contributions, try to optimize, check the coding.
Do optimization and trace again, check again 10 Top contributions ....

I would like to know if there is a way to add multiple borders to a single cell or selection of cells in one click. At this time, if i want to add for example a top border and a bottom border to a single cell I have to do this in two steps: first select the top border, style, thickness, and color, and then next select the bottom border, style, thickness, and color. Is there a way to select the top and bottom border of a cell in one click? Clicking on the top border then holding down the command key while selecting the bottom border does not work, nor does holding down the option key, the control key, or the shift key work. Thanks for your help.
Thank you for the suggestion but this did not work for my Mac. When a cell is selected for which I want borders, the entire cell is lit up. Then when I go to the border tool and select style, thickness, and color, the entire lit up cell takes on the border, that is the Outside Edges of the cell now have a border. So selecting the style, thickness, and color first doesn't work.
If I select the top border first (or any border), the drop down goes away and I can't select multiple borders - I get to choose one at a time. After selecting one border, style, thickness, and color, said border is now on the spreadsheet. Then I go back to the border selection and pick another border and the the previously selected style, thickness, and color reverts to null, so I start over with the new border style, thickness, and color. Yes, it is tedious.
The Fix would allow the user to select multiple borders, say left and right, before the drop down goes away after selecting only one border
Does it have something to do with Allow or Disallow border selection?

Running BitLocker/MBAM 1.0.1237.1.
About 1 month ago, "Last Contact" date/time listed in MBAM "Enterprise Compliance Report" stopped updating (last updated 1 month ago) for all systems. However, reporting against these exact same systems individually via
"Computer Compliance Report" shows current/correct "Last Contact" date/time (last updated today).
Have tried http://support.microsoft.com/kb/2620269/en-us but no luck.
Hoping someone has experienced this before, fixed, and can share insights.
Thx,
DCLYou may want to look for communication errors under the MBAM node in Event Viewer.
You may also want to review the registry settings discussed under the

Limit of time for recording?
Hi,
I need to record an interview which is 2-hours long with my computer. I would like to use Soundtrack (which come with Final Cut Express HD). I don't want any interruption during I'm recording... it's very important for me.
Is it a good idea tho record during 2-hours with Soundtrack? My hard drive has as much space for that, but I don't know if my RAM or the software are correct for that...
Thank you very much,
François
Soudtrack version: 1.2.1
Note: I know that Final Cut Express HD is not working on Intel, but Soundtrack is OK...with each minute of 16bit/44.1khz/stereo audio at 10Mb in size, two hours would be ~ 1.2Gb.
So your relatively new MBP would most likely still have available space, and w/512Mb RAM, you should be fine.
The only way to use SoundTrack Pro on Intel natively, is to buy the Final Cut Studio package. All the other versions of ST/STP are PPC only. Of course with Rosetta translation, ST or STP should still run on your MBP.
Ideally, you would have an external FW drive to record to, as this would free up the boot drive from having both to host the operating system tasks and also capture your incoming audio simultaneously. However, I would bet that the overall system speed of the MBP would still allow you to record without problems.
Post back and let us know how you do ! -
I have an iphone 5 which actually connects to my car (Infiniti FX35) bluetooth phone system, and I want to know if I buy, for example, the Cobra iRadar (which connects via Bluetooth with the iphone) it can be connected simultaneously with my cars phone bluetooth?
If the car bluetooth manage the phone audio while the iRadar (irad-200) manage data (i think), they can be simultaneously connected to an iphone?Yes, the iPhone will support multiple simultaneous bluetooth connections as long as they are not using the same profile.
I use a bluetooth heart monitor and bluetooth headset at the same time with my iPhone on a daily basis. -
Does anyone have time for this one? photoshop 2014 gradient not working.
Working on a project with photoshop 2014 updated thursday night using foreground to transparent gradient. The edges of the picture are staying white instead of being transparent over the background or other pictures. I thought I was using the gradient correctly converting the pic to a png file, setting the mask, then applying the gradient to the edges. Is there something I am missing??? Please help.
below is a snip of the effect i am looking for. i remember it working in the trial version late 2013 photoshop. it was so simple i thought it would be hard to forget how, but i must be missing something. i looked, clicked and checked all around the work space to find a way to change from "background layer" and did not find it. the trial version (lets call it "trial period" because its all the same except paid for now along with updated to ps 2014) did also have the layer change in an easy to find way. i believe it was double click or right click over the currently active layer in the list as in the lower snip pic.
the pic above did work during my trial period so i know it works somehow. i dont know what i am missing now. right click or double click now does not bring up the layer type selection in the menu like you suggested to change from backgroung layer. also every new picture file i open makes its own new layer. when i make a new layer i havent figured out how to put a pic in it. if you could show me how to create this effect or find my missing step that would be awsome. -
