• I have an ACER model AX1430G-UW30P, how to turn off mode standby?

  This computer is asleep after 10 minutes and the scan aborts and long printing print jobs. I would like to deactivate "standby"

  Hi Don Roberts,

  Thank you for visiting Microsoft Community.

  According to the description, the system goes into sleep mode after about 10 minutes and he abandoned jobs scanning and printing for a long time. Now, you want to disable the mode standby on the system.

  Certainly, I understand your concern.

  I would suggest trying the following steps and check if that helps.

  1. Click on the power icon on the tray on the taskbar and then click on "Power Options more." Will launch a new window.
  2. Click on the radio button 'High Performance' under 'Hide supplemental pension plans' and then click on "Change Plan settings". Will launch a new window.
  3. Click "Never" in each of the categories apart from the following drop-down list-"turn off screen" and "Put the computer to sleep."
  4. Click "save changes." "Sleep" mode is disabled.

  For reference:

  Also, I suggest to refer to the following articles given below and check if that helps.

• Transaction is written to the log file and it is not written to undo tablespace. During a failure of the system how oracle rolls back the transaction.

  Hi all

  My question is:

  Transaction is written to the log file and it is not written to undo tablespace.

  During a failure of the system how oracle rolls back the transaction.

  I have already provided the answer, you ignored if well (you seem to only read the responses by people of your country).

  Redo log is always written * first * before * writing to the data block (redo log writing is much more aggressive). So it DOESN 'T MATTER if you lose these scriptures of rollback segment.

  Valuation: rear roller followed by roll forward, using redo log files and/or archive redo log files.

• How to reduce the UNDO Tablespace

  Hello
  We had an UNDO Tablespace to 22 GB but it's using just 2GB. How to shrink the undo tablespace. We use the database in production cluster 3 node 10.2.0.4
  Is there is way we can worry about UNDO Tablespace or should I create an UNDO tablespace and assign the undo tablespace to DB and let fall the old CANCEL?
  How to ensure that the transactions are done and free to abandon the old CANCEL?
  That's what we must restart all three nodes each node has its own UNDO Tablespace.
  
  Need help on this issue.
  
  would appreciate your quick response.
  
  
  Thank you

  There is no such thing/mandate/matter. Undo tablespace (in automatic mode) in relation to the proceeding but no single tablespace.
  There are relationship instance<=> Cancel tablespace(its own) , and it is determined by UNDO_TABLESPACE.

• Notifications not working when phone Mode standby

  Hello

  I took delivery of my Z3 Compact last month, and overall it is very good. This is completely standard, out-of-the-box, with no apps that affect the system.

  I found a very annoying problem with the Notifications sound when the phone is in mode 'sleep', IE the screen completely black, either due to the function of time-out or when I press the round power button.

  The problem is that no notification not crossed; If I'm expecting an email from work, I constantly to wake up the phone and as soon as the lock screen appears, then do the notifications.

  How can I get the phone to always send a notification sound, even in mode 'sleep'.

  Thank you

  Hello and welcome to the community! Since you are new, please make sure that you have checked our Forum.

  It seems that you have activated the STAMINA mode in your phone via the settings > power management > STAMINA mode. You can add apps to stay active in mode if you go to settings > Power management > STAMINA Tap mode > active Apps in mode standby.

• It will frequently commit resolve ora-30036 (cannot extend the undo tablespace)

  I use 11.2.0.3 database. I confused on the use of validation to resolve ora-30036.

  I have the script in migration once that has many updates and I'm getting ORA-30036 (unable to extend segment by 4 in the "UNDOTBS" undo tablespace) .

  Our undo tablespace in NO mode autoextend and like this is just a one time event, we will not increase it.   He is currently 6 GB.

  We would commit determination ORA-30036 in my case? If not why? Is there a better solution to solve it.

  
  

  When I say commit frequent, I won't commit after each line, I just want to commit after may be million lines, so that my active cancellation extend turn into cancellation remaining will extend and Oracle will be able to use it in case of pressure of space.

  
  

  Note:

  UNDO_MANAGEMENT: AUTO

  UNDO_RETENTION: 2700

  Undo tablespace retention is NOGAURANTEE.

  I have the script in migration once that has many updates and I'm getting ORA-30036 (unable to extend segment by 4 in the "UNDOTBS" undo tablespace).

  Our undo tablespace in NO mode autoextend and like this is just a one time event, we will not increase it.   He is currently 6 GB.

  Why don't you increase it?

  You must use the correct size of UNDO necessary for the work that will be done.

  A lot of shops to create a for big lots new UNDO tablespace and then switch to it for batch processing. Once the task is completed, they switch back to the normal UNDO. That prevents the normal RETURN of autoextending far where it is normally necessary:

  ALTER SYSTEM SET UNDO_TABLESPACE
