• Technical questions about X 1 carbon Touch base

  Please forgive me, I'm still recovering after the shock and frustration generated by dealing with Lenovo Tech Support.

  I recently received my X 1 carbon Touch and I have tried to understand some - I think - fundamental questions.

  As you know, to win 8, Lenovo doesn't have a custom recovery solution / owner. However, there are a score of Lenovo recovery on the machine. I'm /assuming/ this, somehow, can be used through the default / built-in mechanisms of recovery Windows, but I want to know exactly how without necessarily experiencing myself with it.

  In addition, the computer seems to be equipped with a mechanism of alternative stand-by, fast recovery called Intel or something like that. It is enabled in the BIOS and apparently makes use of a hidden partition of ~ 8 GB on the SSD. However, I find no indication of this mechanism working. There are no settings that I could find in Windows. I changed the BIOS to 'Immediately' setting in order to test the functionality, but put the computer to sleep does not seem to generate behavior that is somehow different from regular sleep.

  In any case, I would like advice or information on my questions above. I understand works the thing of recovery fast in order to decide if I want to recover the partition or not. I would also like to know my options I should never need re - install the delivered factory OS without actually crossed the steps. I would also if someone could tell me the best way to get support from Lenovo.

  / * I called Lenovo technical support with these issues. The person sponsor and those to whom I then was sent to had no idea what I was talking about. They had difficulty understanding terms like partition, standby, sleep, resume, and even software/hardware and implementation. It was suggested that my computer may be Intel and Lenovo not... They seemed to really come from an age of the computer. I asked to speak with someone who would have some basics of the machine that Lenovo delivered to me. I find it reasonable. At that time, I was told to talk to a knowledgeable person, I have to pay a fee. Seriously?

  elfstone,

  To find out how to work the various Windows recovery methods, please see this Microsoft Web site:

  http://Windows.Microsoft.com/en-us/Windows-8/restore-refresh-reset-PC

  The sole purpose of the recovery partition is to work with the "All delete and reinstall Windows" function of Windows 8.  If you have specific questions about the factory recovery that you can't get items from Microsoft, let me know.

  Regarding the plan of hibernation from Intel, as you noted, it takes a partition dedicated to your SSD which cannot be used for other purposes.  The only parameter in Windows is inside the application of arrangements of Lenovo in the power section.  Lenovo calls this function "in waiting for 30 days.  The only thing you can do is it turn on or off.  Here's how works "waiting for 30 days:

  1. When you close the lid, or otherwise put the system into standby mode, the system of standby for 3 hours.

  03:02 hours, the system will wake up and check things like not attached AC, wake-on-LAN not activated, USB device not attached, etc..  If conditions permit, the system will enter wakefulness of 30 days for example deep sleep.  If the system returns in normal mode to 'sleep'.

  3. deep sleep means that the content of the memory is written on the special hibernation on the SSD partition.  It is very similar to the traditional hibernation except what happens faster using methods of BIOS instead of Windows methods.  But this isn't anywhere near as fast as normal sleep/recovery.

  4. the system out of deep sleep when the cover is opened or when you press the power button.

  You have found the BIOS settings, but in fact they are ignored when Lenovo settings (and package of dependence of the Lenovo parameters) are installed on the system.  I don't really know why this design choice has been made.

  Personally, I don't see value in 30 days standby, not enough value to want to give up my expensive SSD 8 GB.  I exclusively use sleep/recovery.  The battery will last several days.  And if I'm going to be away from the computer for a long time, then I'll just stop it.

• INS-20802 question on Oracle Linux 6.2

  Hello
  
  first of all thank you for reading this post.
  
  I tried to install Oracle 11 g on Oracle Linux 6.2. I have problems due to the lack of some libraries (I thought that Oracle linux would have them all).
  
  After I made that my linux complies with all the requirements, I tried to install Oracle 11 g without removing the few files I already had the first attempt: does not have any sw, a few scripts.
  
  Everything went well until what netca tried to configure a listener: his attempt was set up using port 1521, which was already in use.
  
  After skipping this step, Setup is complete. So I tried to configure the listener is to run the netca myself. Any port number that I use, he repeats that it is already in use.
  
  I also tried to set up a listener.ora myself, using a different number of port 1521, of course, but when I use LSNRCTL to launch up to... it indicates the port number 1521 is already underway to use and the attempt fails again.
  
  One last try was to use the tool to uninstall to remove the database. It worked. Then, when I tried to install again this question INS 20802 showed once again.
  
  Someone knows how to fix this? I am totally lost and cannot find all the useful information.
  
  Thank you in advance for your help!

• Question about Oracle schema E/R database dictionary

  Hello
  
  As we know, the dictionary in an Oracle database is a fairly large beast. I was wondering if there was an ERD of the tables/views most commonly used or available useful. That would make familiar you with the dictionary quite a little easier.
  
  I've been Googling for such a scheme, but without success.
  
  The question is: does anyone know where such a diagram might be available? If Yes, where?
  
  Thank you for your help,
  
  John.

  Are you talking about view DBA_xxx (DBA_TABLES, DBA_USERS, etc.) or V$? If you're talkink about DBA_xxx views, please google with "poster oracle dictionary '..."

• Qosmio F20-136 - Question about installing Linux in virtualization

  I have Windows XP MCE 2005, Ubuntu 8.10 & openSUSE 11.0 on my laptop F20-136 (triple boot).

  I intend to:

  0 save the partition Windows XP MCE 2005
  1. remove all the.
  2. install openSUSE w / Xen Virtualization.
  3. then create virtual machines to run backup Windows XP MCE 2005, new 8.10 of Ubuntu and other linux distributions.

  The questions are:
  1 F20-136 requires Windows XP MCE 2005 as its main operating system?
  I ask this question because I noticed that when I disable the builtin speakers in XP, I can't turn them on when I boot in openSUSE.
  So it seems to me that XP with Toshiba drivers and other software on Toshiba system has complete control over the material.

  2. will it affect Qosmio player?

  3. is there any other software virtualization is better than openSUSE w / virtualization Xen?
  I know MS Virtual PC, VMWare, VirtualBox.

  Please note that probably I don't want Windows XP MCE 2005 + virtualization (which will be my last option). I would like to have virtualization using Linux, openSUSE preference as he impressed me with his ability to (fast start/stop<= 45="">

  After further investigation, I think of virtualization VirtualBox which offers a bare metal solution, i.e. without operating system host is necessary.

  VitualBox (hypervisor) layer can be installed directly on the hardware, and then the virtual machines can be created for different operating systems.

  In this spirit, I have queries:

  Say I back up the entire hard drive (just in case the plan everything is the draw, I would restore the image of the entire hard drive), delete the contents of the entire disk, install VirtuaBox.

  1. let Qosmio player as well, which by my understanding, is 10 GB of free space somewhere on the hard drive?

  2. I would be able to install XP MCE recovery disk to create a virtual machine?

  Thank you

• Question about oracle objects

  Hi people

  I came across the below example on the oracle documentation.

  I'm not quite sure why "emp is NULL #2' always get printed even if the Member attribute is assigned a value that should be non-NULL and" ""emp is NULL #3"isn't even after printing has been assigned to the object with a NULL value."

  Can one of you you please explain about it. or give the overview of the conditions of the NULLable object. Thank you!!

  DECLARE

  EMP employee_typ; -emp is atomically null

  BEGIN

  If emp IS NOTHING THEN DBMS_OUTPUT. Put_line ("emp is NULL #1"); END IF;

  IF emp.employee_id IS NULL THEN

  DBMS_OUTPUT. Put_line ("emp.employee_id is NULL #1");

  END IF;

  EMP.employee_id: = 330;

  If emp IS NOTHING THEN DBMS_OUTPUT. Put_line ("emp is NULL #2"); END IF;

  IF emp.employee_id IS NULL THEN

  DBMS_OUTPUT. Put_line ("emp.employee_id is NULL #2");

  END IF;

  EMP: = employee_typ (NULL, NULL, NULL, NULL,

  NULL, NULL, NULL, NULL, NULL, NULL, NULL,

  address_typ (NULL, NULL, NULL, NULL));

  -emp: = NULL; -It would have made the following statement of the TRUE IF

  If emp IS NOTHING THEN DBMS_OUTPUT. Put_line ("emp is NULL #3"); END IF;

  IF emp.employee_id IS NULL THEN

  DBMS_OUTPUT. Put_line ("emp.employee_id is NULL #3");

  END IF;

  EXCEPTION

  WHEN ACCESS_INTO_NULL THEN

  DBMS_OUTPUT. Put_line ('impossible to assign object NULL value');

  END;

  /

  The result is:

  
  EMP is NULL #1
  EMP.employee_id is NULL #1
  EMP is NULL #2
  EMP.employee_id is NULL #3

  I came across the below example on the oracle documentation.

  I'm not very sure why 'emp is NULL #2' always get printed even if the Member attribute is assigned a value that should be non-NULL and ' emp is NULL #3 "is not get printed even though the object is assigned to null."

  Can one of you you please explain about it. or give the overview of the conditions of the NULLable object.

  Have you actually tried this example? Why not?

  The best and often faster, learn is to DO - not just read.

  If you tried this example, you would see that you have been "bitten" by a documentation bug.

  EMP.employee_id: = 330;

  That the line of code won't work - it will trigger an exception is the output you get really

  PEM is NULL #1

  EMP.employee_id is NULL #1

  Can't assign value to the NULL object

  PL/SQL procedure successfully completed.

  SQL >

  The 'emp' instance has the value NULL as shows it the first message. If you cannot assign the 330 value him.

  For others, the example seems to be the Oracle documentation

• A technical question about Oracle11g GI - settings Clusterware: misscount

  Hello

  We are working on 2 - node RAC environment with below configuration

  Oracle11g 11.2.0.3.0

  ASM

  REHL 6.4 64bits

  As we know that misscount represents time in seconds that a heartbeat can be missed before entering a cluster reconfiguration to remove the node.

  Oracle default values for these parameters is the following:

  seconds 10g RAC 60

  11g RAC 30 seconds

  can configure us the misscount in 3 minutes or what is the recommended h/s or bone or the n/w configuration to avoid misscount reached the question?

  We have two available switches - Switch-A Primary and secondary switch B

  We use Cisco or nessus switches L2 or L3, which usually takes 3 minutes during the rocker switch / switch reboot/connector and unplug operation.

  We can over come this problem with the binding Configuration? What is recommended for the binding configuration mode (with A N1 and N2 with B)?

  What to do to overcome or hit the question of the achieved the best @ level CARS.

  Thanks in advance

  Hitgon

  It is not supported by oracle workaround switch failover to the misscount parameter.

  Consult the MoS note: calculation of CSS in Oracle Clusterware (Doc ID 294430.1) timeout

  I have, of course, that Oracle will not be supported, you set 3 minutes away from misscount.

  This will compromise the integrity of the cluster.

  Suppose that you set it. If you have any other related issue e.g. CPU or i/o starvation, Oracle wait 3 min to start the node.

  3 minute wait an IO operation is complete without warranty who is successfully completed is a big risk.

  Do not hesitate to ask the Support of Oracle.

• Question about Oracle sequences

  Please let me know if this question is not the subject of this forum and advise which forum I should post it. Thank you.
  
  We have a database 10g running on the AIX servers. A process of data loading was recently, and the development team is of the opinion that the question can be corrupted in the database sequence. This sequence is used to generate a unique primary key for writing in a table.
  
  Are there problems with 10g about the objects sequence database becomes corrupted? If so, is there a Metalink note published on a fix?
  
  Thank you all for a light on this topic.

  Hello

  Interview the max value of your column of tabale, in order to know the populeted of the maximum value of the sequence, compare it your currval in the sequence, and the maximum value for the column. If the values are not the same and the currval is lower than the max value, you will probably have the constraint violation, then increment the value of your sequence curr.

• Technical questions about the development on the BlackBerry PlayBook

  Hi, guys

  Hope this is the right place to post my thread...

  I was asked to develop an application on BB PlayBook (I'm an absolute beginner on this point, however), and now what I have to do is:

  place an image in my application, and tapping on the image, the application will open a. PDF file.

  However, I'm stuck here because I did some research on this one, looks like on BB PlayBook, the only way to open a. PDF file is to be opened with Adobe Reader (version BB). My 2 questions are:

  1. how to call the Adobe Reader to open a. PDF file in my application? I tried the "browseForOpen' from the 'File' class method, it opens a file picker in my application, and I can see the. PDF file here, however, when I select the file and click 'Open', it will not open the. File PDF... and, of course, it will not

  2. based on question 1, on BB OS tablet is it possible to open a file without showing up the "file selector"? I would like to have the opened file directly as long as I click on the image that links to the file.

  I would be grateful if you could give me a quick points up on this.

  PS: I use Adobe Flash Builder 4.5 as the dev. IDE and build up my app as a Flex app.

  See you soon!

  Terry

  Try the function navigateToURL (...). In addition, the class File (openWithDefaultApplication) and QNXApplication (openFile) class contains the methods to open applications preferred, based on a file.

  Before BBX 2.0 Beta, these two methods did the same thing (it didn't). It has been reported as a bug, but I'm not sure if that has been resolved. Need to try all 3 methods to see which works for your needs.

  Thank you!

  Interesting question.  PF stands for package of plug-in filter in After Effects.

• Question about Oracle identity analytics

  Hello
  
  Is it possible in Oracle identity analytics (version 11.1.1.3.0) to compare the datas in OIA and data in LDAP for example?
  
  The goal is to see the differences between this 2 databases for roles and strategies.
  
  If possible, can you tell me how to make that comparison?
  
  Thanks for your help...

  I think not - OIA with no agents / connectors. What you can be able to model the data in the LDAP protocol as a resource in OIA and run a report against that?
