• Setup of SCANNING using the file/etc/hosts

  DB version: 11 GR 2
  Operating system: Sun Solaris 5.10
  Node 2 Rac
  
  
  I've done all the configuration of connectivity hardware/software/SSH for the installation of RAC. Now I have connected as a user of grid and try to install the clusterware ('Grid Infrastructure')
  
  I have implemented Public IP and IP private for nodes according to the oracle documentation. We do not have DNS for these nodes. So we thought to use the file/etc/hosts.
  

  Node1's: Public IP : 10.80.143.214
  Node1's: Public IP : 10.80.143.215

  Question1.
  When I ping 10.80.143.219, it wrong; which means that this IP address is not allocated (not used by any node), so I tried to add the following entries on the file/etc/hosts of two nodes

  10.80.143.219  danube-scan.scott.com  danube-scan
  10.80.143.219  danube-scan.scott.com
  10.80.143.219  danube-scan  

  None of the above worked, and I kept getting

  INS-40718: Single Client Access Name (SCAN) name:string could not be resolved.

  Can someone show me how as the SCAN entry next to the file/etc/hosts?
  
  Question2:
  The file/etc/hosts, how Setup identifies that a particular entry of the IP and host name is intended for ANALYSIS. If the word "scan" to be present in the SCAN entry?
  
  Question3:
  The grid Setup will prompt you for
  1. name of the cluster
  2 SCAN the name
  3. port SCAN
  
  For a Cluster name. I can give any name that I love. Right?
  
  
  Question4.
  
  SCAN name must belong to a domain of DB as (scott.com as shown above). Cannot create a database RAC 11 GR 2 without belonging to a field of DB?

  Hello

  Try ping this host of the danube-scan in any army, this command must resolve this name in all hosts.

  That is to say: the server does not respond to the PING, but must indicate the IP address.

  Check...

  The 10.80.143.219 IP address must be the same subnet in the public network.

  This section below should be/etc/hosts in all hosts in the cluster.

  the danube - danube-scan scan.scott.com 10.80.143.219

  To configure your host to perform searches in hostname to host files, change the line that starts with hosts: to include the keyword files. For example, if your file /etc/nsswitch.conf hosts line looks like:

  hosts: files dns

  Change it as follows:

  hosts: files dns

  The order of keywords on this line indicates the order in which made Solaris reference the name of services. Keyword files represents the file/etc/hosts.

• vCAC 6.0: keep coming back after the reboot of the file/etc/hosts

  HI guys,.

  I am running vCAC 6.0, I noticed that on my identity server's host name is not COMPLETE and I also noticed that I have big fingers DNS server settings.  I can fix this in the user interface and I confirmed that the/etc/hosts and /etc/resolv.conf have been updated correctly.

  However, if I reboot the server all restores the original files.  Same thing if I modify the file manually with VI.

  I saw exactly the same thing with vCOPs.

  Any ideas?

  Ben

  I am not sure what is causing the reversion.  Reinstall the identity a vCAC using the FQDN and things got appropriate DNS works...

  What's my configuration "/ etc/hosts" correct?

  That's if you want all references of this machine 'dbhost' or 'dbhost.mydom.com' to resolve to address IP 192.168.1.101 and all references of this machine to 'dbhost2' or 'dbhost2pc.mydom.com' to resolve the IP 192.168.1.100.

  Is it mandatory to have the first line with "127.0.0.1..."?

  No, it can be anywhere in the hosts file. Strictly speaking, it is not yet mandatory to have at all, but as the poster said, if you delete it, some features may be lost.

  All net communications should go down to an IP address. The hosts file is nothing else that a mechanism to map a name to IP address. This allows you to return a destination by name, and really, this name can be anything you want. Resolving to 127.0.0.1 ' localhost' is a universal standard which depend on some process.

  Hi Kasggr,

  You are be prompted for approval because of her User Account Control (UAC) and it is not wise to turn off UAC.

  User Account Control (UAC) is a feature in Windows that can help prevent your computer from unauthorized changes. This UAC asking your permission or an administrator password before performing actions that may affect the operation of your computer, or that change settings that affect other users

  By verifying these actions until they start, UAC can help prevent malicious software (malware) and spyware from installing or making changes to your computer without permission.

• Guest VM Mac - IP address and the file copy host

  Hi all

  I'm involved with the automatic configuration of the guest virtual machines in Mac. In this context, I want to start and stop the virtual machine automatically. Also, I want to copy files between the host and the guest and launch programs automatically in the comments.

  System details:

  VMware Fusion: Version 3.1.1 (282344)

  Host of Office Mac: OS X 10.5.8

  Comments to VMware Mac: OS X 10.6.2 Server 64-bit

  VMware Tools installed

  1. I am able to use the vmrun as 'start', 'stop' commands, etc. But I'm unable to use the controls of the operating system called as 'runProgramInGuest' and 'copyFileFromHostToGuest '. I understand an exhaustive search, Mac Guest VM does support all the vmrun commands. Please specify if this isn't the case.

  2. because the vmrun commands do not work, and I always want to copy files to the guest, I try to get the IP of the host Mac address to connect to the FTP host - essentially treat them as 2 different machines on the network. Please specify whether it is possible to get the IP address of the Mac Guest VM and copy the files in the manner described.

  Thanks in advance,

  Hema

  Hi Hema,

  Welcome to the forums.

  I have no experience with the Fusion, but I had to work on the same problem with VMware Player. If your guest is using NAT network connection, you should be able to find its dynamic IP address in the DHCP leases file placed at:

  -/var/db/VMware/vmnet-dhcpd-vmnet8.leases

  As long as you know its mac address, you should find its IP address.

  It may be useful

• Function of the file/etc/Upload of an open file of the application, using the file as a utility Explorer, does not work on my Win7 PC.

  If I run the file Explorer (open) by itself right clicking the my computer icon on the desktop, or work when I double click on the shortcut to My Documents on the desktop, all files are visible (except the system and hidden files, by default, of course). I don't think it's File Explorer itself, for reasons described. It must be an add-on, or ACCELERATOR, as it is called when this functionality is provided for other applications or the Internet Explorer browser. 10, IExplorer even the fact when I want to attach a file to an e-mail in the tab of the mail.live.com browser or dialog box that prompts for a download location and the source file. The only place where I can browse the file Explorer to display its content, is the office. I have automatic updates for all my Windows software installed on my PC, as well as for all my applications. This happened for months, and the only work around is to copy the files to the desktop, take them out there in my app/browser and then delete. It's a pain in the thigh not only because of the increased workload, but also because my OS is running on a very small SSD drive (128 GB), reserved for the windows and the user * he pours on the system drive. All this extra activity write/erase on my system drive is exhausting the ability of my SSD FLASH prematurely. All my software is installed (when installing allows) on my D: drive, but it has been so since I ran Windows 98, it is NOT the cause of the problem. Any help will be appreciated!
