• Cannot get 2 nodes VM talk to each other on OEL7

  Greetings-

  I intend to install RAC 11 GR 2 on OEL7. I got the Oracle VM operational machines. I can access the internet successfully without any problems. If I'm on the node-1 and ping its IP address, it also works very well.
  But when I try to do a ping of virsa node-1 node-2 and vice, I get the message cannot.

  Here is my configuration of hots of installation:

  [oracle@racdev01 Desktop] $ cat/etc/hosts

  Loopback #.

  127.0.0.1 localhost.localdomain localhost

  # Public

  192.168.56.71 racdev01.localdomain racdev01

  192.168.56.72 racdev02.localdomain racdev02

  # Private

  192.168.10.1 racdev01 - priv.localdomain racdev01-priv

  192.168.10.2 racdev02 - priv.localdomain racdev02-priv

  # Virtual

  192.168.56.81 racdev01 - vip.localdomain racdev01-vip

  192.168.56.92 rac - scan.localdomain rac-scan

  192.168.56.93 rac - scan.localdomain rac-scan

  Rattling, public and private maintains for lack of node-1 node-2 IPs and vice versa:
  $ ping racdev02
  $ ping racdev02-priv

  I tried for days to get these 2 nodes to talk with each other. I would really appreciate your help to solve this problem... I can't installing RAC, unless I get these machines talk to each other...
  
  Thank you very much!

  @AJ

  First of all, thanks to you all for the heads up, I tried your suggestions, which was a good experience of troubleshooting since I am just a DBA not a network Admin however, I solved the problem and I share the solution below.

  Initially after a successful installation of OEL7 on Node1, I did not perform a fresh install of OS OEL7 on Node2, instead, I took the short cut by saving Node1 via VM - Box > file > Export device and then reimported into a new host name & configured network connections accordingly. But, since a clone of Node1, Node2 machines will have the same MAC address and so they may never talk to each other because I understand is the address MAC is what distinguishes them from material level.  Now, you should have a good idea what is my problem...

  There is a quick fix & fix liked - the longer fix would have been to install a new OEL7 on Node2, the miracle solution is below which I was working with success:

  1 I changed my MAC address last 2 digits for all 3 node-2 and make unique cards and not the same addresses MAC on Node1 because they were copied from Node1.

  2. to: VM - Box > settings > network > adapter 1 > advanced > change the 2 digits of the MAC address here also with the same 2 numbers I did on step 1

  3 step 2 apply for Adapter 2 and 3 of the adapter, but make sure you use the same last 2 numbers you did on step 1 for Adapter 2 and 3 of the adapter

  Exp: 1 MAC adapter: 08:00:27:96:72: 85 -adapter 2 MAC: 08:00:27:96:72:86 - 3 MAC adapter: 08:00:27:96:72:87 > Note: they must all be unique and different from MAC @ on Node1

  4 on Node2 > Terminal > cd sysconfig / > , you should see, in my view, enp0s3, 8 and 9 may be different numbers according to your configuration. But once you change each of them, you should see a setting called [HWADDR] Exp: mine was: HWADDR = 08:00:27:96:72:84 - then I changed to the same number, I put it in step 1 above - to: HWADDR = 08:00:27:96:72:85.  Apply the same changes &

  5 restart services network as follows: service network restart - may have to restart...

  6 if everything is done correctly above, you should be able to ping both machines of vice versa - I could

  7 nothing succeeds like success! It took me 2 days to understand this point, but it was worth. I learned so much by testing a few things around. The other way is to perform a new installation of OEL7 on Node2, modify the connections accordingly and you don't need to mess with MAC address at all...

  I'll be happy to set up a small video or post screenshots so you can see it working.

  Please note, I've looked all over youtube BOF CARS on OEL7, most 2 knots BECAUSE I fell on were on OEL6.5 and below. I've seen some autonomous 12 c on OEL7, but no 12 c CARS on OEL7. If there are out there, please post the link. Now, I had 2 machines to talk to each other, I will perform with installation 12 c CARS on OEL7.

  See you soon

• With Movieclips talk to each other

  Hi all.

  I can't try to have a video clip to talk to each other. Essentially, I nested within a movieclip buttons. I want to do is have it such that when one of these buttons is activated, it tells an another movieclip I have on the stage to move to a certain range.

  So currently I have two clips on the stage - navStart and navArrow. I have a navStart button that reads:

  function goMoviesArrow(Event:MouseEvent):void {}
  gotoAndStop (1);
  navArrow.gotoAndStop ("movies")
  }

  Now when I click on the button I get an error message that there is an access of undefined property navArrow. I understand why this is... it is because in the movieclip navStart... There is no such thing as navArrow. So, how can I say that it resembles navArrow who is back on the main stage. I tried things like:

  parent.navArrow.gotoAndStop ("movies")

  and

  stage.navArrow.gotoAndStop ("movies")

  but in vain.

  So, how can I get these movieclips to talk with each other?

  The zip file is attached...

  Try:

  MovieClip (this.parent).navArrow.gotoAndStop ("movies")

• Can we have three VM servers with software very often talk to each other.

  Hi, I'm new user who started looking for in VM yesterday. I have a requirement where I would like to split a server using VM in 5-6 servers. I would use a VM to install SAP R/3 IDES, another to install SAP CRM IDES, third to install BO and the fourth where I access these three applications. These three programs should talk to each other very frequently. Please let me know if this is possible. These three will be will have separate IP address?

  Please also let me know that all the software are required. If I can get VMware free so what's the advantage with VMware eSphere which cost a lot (for personal use).

  This I do for the self-study that I need to install 2-3 software on separate machines so please be easy on the cost.

  I suggest buying a Dell/HP/IBM server 1 Quad Core with 8 GB of RAM and a SATA drive at least 2.

  Check compatibility on http://www.vmware.com/resources/compatibility

  With 4 cores and 8 GB of RAM, you can run all your VMS and something else (like the gateway VPN or TS, a domain controller for your Windows environment,...)

• How to get 2 vm talk to each other?

  Guys,

  I'm on a 64 bit Windows 7 machine.  I have VMWare Workstation 7.1.4 and I try to get 2 Windows 7 64 bit VM to talk to each other without network connectivity.  At present, we have setup the network adapter for the two virtual machines as host only, and also two Windows firewalls are disabled.

  We put the IP (192.168.1.1 and 192.168.1.2) manual on both.  We connected to both and tried to do a ping to another, but it times out.

  What do we lack?

  TIA!

  In order to do a ping, let the firewall is turned on in the Win7 guests and allow ICMP traffic in the advanced settings in their firewall settings.

  How can I display two PDF files next to each other?  In the older version of Acrobat Reader, I was able to open each PDF in a separate window and used all the time.

  Hi julians7844423,

  Open Acrobat Reader DC, navigate to the Edit-> Preferences-> General-> uncheck "Open Documents in the new tab in the same window.

  Restart your system & now try to open PDF files.

  Let me know if it solves your problem.

• CAN´t get rid of annoying HP message each time I feel.

  I m having a problem with my printer of HP and the Brazil Support he not resolved!

  I had to reinstall Windows on my laptop due to a hard drive crash, and I used the recovery disks provided by Dell.

  I downloaded the latest driver for my HP OfficeJet 8600Pro: 'OJ8600_1315.exe '.

  Whenever I print, I get the pop-up below:

  

  «Thank you for using the original HP cartridges...» Click HP REWRDS for more information"

  I click on "no, thank you, g * t * h *.

  Next time, I feel, it shows same again.and pop up again and again once and again and again and again...

  I called technical support on + 55 11 4004-7751, matter is referred under the 3002909186 Protocol.

  The tech guy asked me to remove the driver and reinstall it. I did, and I have selected disable all unnecessary features such as TheGoogleWannabe (Bing), HP, HP Update, etc help - did not solve...

  Then he asked the 'level 2' tech guys and they put the blame on Windows, because windows did not record my option "no, thank you '... this ugly response!

  As said before, I used the Dell recovery disks, so I use a 2 weeks fresh, Windows 7 original.

  I hope that there is a better solution than downgrading the driver to a version that had no 'rewards' c * p.

  You know, sometimes good old stuff is better than the new.

  I solved it by myself! I m so smart...

  Google-the-great, found this:

  http://h30434.www3.HP.com/T5/Ink-toner-cartridge-printhead-issues/can-t-get-rid-of-quot-genuine-HP-cartridge-s-installed-quot/TD-p/827807

  In "EXBworksmart" long answer is the #1 solution: disable the bidirectional communication and shut up to the printer.

  Solution #2: don't ever buy HP.  I lost $2500 in my HP laptop because it featured a chip nVidia video, which regularly on PC come with a hetsink and sometimes a fan, but on my rating of HP, he was naked nude, not a single piece of metal to circulate the heat. The remark was an AMD processor, it was hot, and the broken video chip BGA solder.

  Finally, I bought a printer cheap of the Brother Laser HL-1112. No scan, no wifi, no colors, no fax. But I can leave it for years and it will print immediately. Of course all HP Color laser printer would act in the same way, but why buy a lower brand that is just good marketing?

  Brother printers are doing the work, the toner cartridge is separated from the drum to return cartridge more low maintenance cost, AND NOT BAD 'BROTHER REWARDS' pop ups!

  Now I m going to call tech brazillian support to teach them. Hold on... Why bother?

  No offenseses in the letter, only the truth.

• Can I get my computer to talk to me?

  Hello

  Several years ago, I saw a movie on TV, where a young kid almost started a war on his computer. The movie could have been called "war games." In any case when the child went to his computer and press a button, the computer said, ' Hello, Richard, what you want to do? (something to that effect anyway). I thought it was pretty clean.

  I'm just wondering, was that television special effects to play or can computers really do? It is a program that you can buy, or it's just something that can do a computer technician, but others do not?

  Thank you

  There are a lot of things.  Google Chrome browser allows you to say 'OK, Google' and then ask questions like ' how horsepower in a Mustang to 2015 ", or" the weather going to be like this weekend?' and he will answer you.

  Windows 10, a free update for all users of Windows 7/8, this will be too, should come out later this summer.

  You can also use programs such as Dragon Naturally Speaking to do the same thing.

• How can I get windows XP to talk to my new HP photosmart C410 series printer all in one? -Thank you

  When I try to install my new HP Photosmart C410 series, it gives me an error message: HKEY_CLASSES_ROOT\CLSID\ {000C101C-0000-0000-C000-00000000006}.    I tried to install several times with the installation CD and the HP Web site.

  I contacted HP technical support, but they were not able to help me.  If this is not resolved, I will run the new printer to the store.

  Thank you

  Please provide the full error message.  Also, make sure that you typed correctly - are you sure that the CLSID does not stop with "46" rather than simply "6"?

  You can also follow the steps in the following article to clean things up and try again: One Article

  • Make sure that you install the printer by using a user account with "computer administrator" privileges (if you are not sure, click Start > Control Panel > accounts of users, under the name of each account will be "Computer administrator" or "Limited account").

  Using IMAP or POP? See https://support.mozilla.org/en-US/kb/glossary-terms-including-types-accounts

  If you use IMAP, you can access e-mail from computers and it will always be available on the other.

  If you're using POP, you can leave messages on the server. Otherwise, when you read a message on one, it is not available on the other.

• WE have 2 macbookpros 10.10.5 - we, recently turned to gmail.  Now, if remove us an email on a single computer - it is removed on both computers.  How can we stop this so that computers operate independently of each other?

  We have 2 macbookpros 10.10.5 - we recently changed to gmail.   now when my wife deletes an email on your Mac... that electronic mail is also deleted on my mac - and if I delete an email on the same account - remove the e-mail on his computer - we don't want that to happen - we want the actions on a computer to be independent of the actions on another computer.

  How can we stop this?

  My first recommendation is that each of you get your own e-mail account. They are free. If you decide not to do this, change to POP3 instead of IMAP Gmail settings. If you connect to Gmail via your browser, go to the settings, then transfer and POP/IMAP. Change to activate the POP protocol for all messages.
