  No out-of-the-box, but there are several workaround solutions if you want to continue an any of them:

  (1) use a view selector. A single report will be a pivot table with the column, the other will have the same report less column. Users can switch reports.

  (2) use a column selector. The two choices would be this column or an empty space. If white is chosen (because the user has no values), the column "will disappear" according to the report.

  (3) guided use NAV. This method involves the intervention of the user. Build a small report using the single column and put a filter "is not equal to" 0. Because there is only a single column, so all lines are 0, the report returns no rows.

  Use this report in the properties of guided navigation from one section of the dashboard. Assign to this "If the report returns lines" and put the report that contains the column in this section. Now add another article on your table edge and in the properties of guided navigation of this section, set on "If the report will return no rows" and it points to the small report as well. In this section, put a second version of your report without the column in it.

  When the column contains all zeros, the second section with column will not display in it; the first section is not displayed. When at least a line contains a value not zero, the first section is displayed with the column, and the second part will not be.

• Exception of null on the list pointer implementing values when there are n rows in the table

  Hi Experts,

  I use JDev 11.1.1.7.

  I have a VO that I defined a LOV with no search box. In my page, I've added it as af:inputListOfValues, but when there is no rows in the table that I will meet with NPES

  Is - this bug?

  Surprisingly, it works very well if there are lines in the table that the VO is querying.

  -Soham

  Soham,

  I think you just create this LOV page by simply moving the VO, right?

  You can select the box to tick 'Include no. Selection' in your VO, and see if that helps?

• Why there is only a single process RFS in v$ managed_standby?

  We build a backup using Oracle Dataguard 10 g server.
  Steps to start this server are:
  SQL > STARTUP NOMOUNT;
  SQL > ALTER DATABASE MOUNT STANDBY DATABASE;
  SQL > ALTER DATABASE RECOVER MANAGED STANDBY BASE DISCONNECT FROM the SESSION.
  
  When we show the process using v$ managed_standby
  SQL > SELECT PROCESS, STATUS, THREAD #, SEQUENCE #, BLOCK #, BLOCKS FROM V$ MANAGED_STANDBY;
  the result is
  
  STATUS OF PROCESS THREAD # SEQUENCE # BLOCK # BLOCKS
  --------- ------------ ---------- ---------- ---------- ----------
  ARCH CONNECTED 0 0 0 0
  ARCH CONNECTED 0 0 0 0
  MRP0 WAIT_FOR_LOG 1 81 0 0
  RFS IDLE 0 0 0 0
  
  There is only a single process RFS. Whereas, when I read articles on the GDO, they mention that there are two methods of RFS.
  
  How to create the RFS another process? Should be to identify what are the parameters?
  
  Thank you very much
  
  Kind regards

• Strange double NAT, although there is only a single router

  My ISP (RCN) changed my modem at a speed greater than one.  Although a router built-in, I told them that I didn't use their router, only my Time Capsule, so they disabled.  However, my Time Capsule kept gives me an error message Double NAT and amber flashing against Green, even though everything seemed to work (wireless and wired) and said that I should switch DHCP and NAT to bridge mode.  Correction of the error, but I do not understand what caused the Double NAT if there is only a single router.  The ISP Technical Support people confirmed their control center is not the router feature on in the new modem, I ask.  They also said that their network supports DHCP, although they have other who use the Bridge Mode, although they do not support.   And they knew nothing about it, he said to ask Apple.  They also offered to switch back, but because this modem is faster at the same price.  (He called a bypass gateway 3-in-1).  Many people online told not to use his router, it's why I unplug it and only use the time Capsule.

  So if someone can give me feedback, I'd appreciate it. I must:

  1. keep running the new modem and my Time Capsule in Bridge Mode.

  2. run the new modem in DHCP mode, as they put in place and do not worry Time Capsule seeing amber / flashing Double NAT error.

  3 swap back to the previous modem, which was 50 Mbps against it with (theoretically) 155 Mbit/s (it's only works in 50-70).

  I'm not really all that, but I hope that one of you maybe.  Thank you!!!

  Although a router built-in, I told them that I didn't use their router, only my Time Capsule, so they disabled.

  ISPS often make the mistake of simply turn off the radio on a modem/router...which service does not disable the router function of the device. You still have a wired router when ISPS are making this mistake.

  However, my Time Capsule kept giving me an error message Double NAT

  This confirms again that the ISP has not disabled the function of the router to your modem/router.  On some modems/routers or gateways, it is not possible to get the device to act as a simple modem.

  The ISP Technical Support people confirmed their control center is not the router feature on in the new modem, I ask.

  The fact remains that you wouldn't see a Double NAT error unless the ISP system acted as a router... Despite what people of PSI say. You may need to get a 2nd or 3rd person-level support, who knows what they are doing.

  1. keep running the new modem and my Time Capsule in Bridge Mode.

  Yes, if you want to avoid the mistake of NAT Double... what you are doing. But, the time Capsule will not be your router.  The device of the ISP will be.

  2. run the new modem in DHCP mode, as they put in place and do not worry Time Capsule seeing amber / flashing Double NAT error.

  This only if you willing to accept the fact that the ISP did not correctly change your gateway to make it work as a simple modem only.  You might be able to get away with a Double NAT error on a simple network, but there is no reason more complicate things with a misconfiguration in unless whether there are a few reasons to do it and it can't be avoided.

  3 swap back to the previous modem, which was 50 Mbps against it with (theoretically) 155 Mbit/s (it's only works in 50-70).

  Your decision if you want to run a simple modem with time Capsule, or accept the fact that the time Capsule won't have your router when it is configured in Bridge Mode, or you see a Double NAT error on the network.

  If it were me, I would go back to what I know will work properly... the simple modem and time Capsule as the router.

  When I have only a single virus of Gabrielle, I know, this program is Mcafee.

  It is not recommended to run two anti-virus programs at the same time.  It will make the System unstable, crashes, slow performance and so on.  It is better to use a program that you trust on a regular basis and if you want to double check this program, use a parser in line one of the main websites AV.

• Error creating of business model

  Hello
  
  I created my physical layer on a server data warehouse SQL with denormalised table without joins.
  
  When I try to create a business of this physical layer model, (drag the columns of 5 or more than one table) and I check the consistency, the error I get is: 38133 - table logical ERRORS: the logic Table < table name > is not attached to any other logical table.
  
  Is it mandatory for a physical to join view table?

  Table in physics or MDB layer had to have a join with any of the table, it could be a free table in training alias, which allows you to delete would help with consistency errors.

• X 230-Turbo Boost does not work when there is only the AC

  I changed the power manager in the State of Performance Max, but when he has only AC, Turbo Boost does not work. I need to install the battary simultaneously to do the Turbo Boost. If there is only battary, Turbo Boost can function normally.

  I googled this problem and it is said that Lenovo is doing this in order to avoid the lack of power when there is AC only.  How could I do Turbo Boost only works with AC (without battary on)?

  "evening.

  Welcome to the community!

  There are here some information that suggests that a 90 Watt power adapter will allow what you want, but I am mobile at the moment so my research capabilities are limited. Personally, I can't confirm that it works, however, I've never run without battery.

• Disable the operating system choice when there is only windows 7

  I have a p7 - 1370t with windows 7.

  How can I start my computer without the need to choose the operating system where there is only windows 7?

  Dean,

  Thanks for your efforts.

  I finally found a solution thanks to eHow.com.

  I had to modify the boot configuration data store by adding the line:

  ' bcdedit/set {bootmgr} displaybootmenu not.

  It took me a few tries because I did not wait for a response after having been first published (impatient, I guess).

  It works fine now.

• How to get 2 virtual NIC works when there is only 1 physical NETWORK card?

  Hello

  Running VM Fusion 2.0

  I want to create a Virtualversion of Ubuntu that will have 2 virtual network cards which is both connected to my NIC physical 1

  I added the network cards successfully, but when I run ifconfig eth0 only arises

  I edited the vmx file by adding the lines below, but without success

  ethernet1. ConnectionType = "custom" ethernet1.vnet = 'vmnet2'

  Someone knows how to do this?

  See you soon

  Tom

  I guess that you configure additional virtual networks in Fusion by using something like: Advanced Networking Configuration - Tokamak Networking Scripts for VMware Fusion , since vmnet2 does not come configured out of the box with the merger and there is no way in the GUI to do.

  I interpret what you're trying to do like the creation of two virtual network cards in a time filled with the same physical NETWORK card in the Mac VM. Can you explain what you are trying to accomplish by doing that? This configuration can cause two interfaces with an IP address on the same subnet, including many UNIX-like (and Windows) nuclei do not take very kindly.

  You may also check the Ubuntu network configuration (to ensure that the new NETWORK adapter is enabled and configured).
