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...

    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.

    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.

    Unless the site you develop is for the Asian market, I don't know why you want to use that particular font. The Basic, standard and digital alphabet punctuation glyphs has sans serif, Roman characters, but the rest is thousands of Kanji characters. While you can use the font .ttf and .otf and web fonts, it would be very unusual to use one so great. Pages should load quickly and 78 MB, with a value of faces to download for those who have connections slow Internet is not fast.

    I would take a different font without serifs. There are literally thousands who look identical or virtually identical to Yuanti.

    131 free and high quality without font serif to choose here. I'm sure you can find a desired.

  • Why Firefox tells me "another program is using the file" 1 hour after the update of Firefox, when I click on the desktop icon?

    It happened when I tried to update c. 16 to 17 as well. I had go it and download v. 18 and he told me that she had and he asked me to restart Firefox. I clicked on the "Restart Firefox" button. He closed Firefox 17. I waited an hour and no Firefox had begun. I clicked on the icon on my desktop for Firefox, and I got a window with "another program is using the file.

    The last time that happened, I had to uninstall v. 16, use Opera 12.12 to download version 17 and then installed, to have to set my preferences just a little and then I could start v. 17.

    Why update your program allows me to update, instead of downloading a new program?

    I'm on Windows XP SP3 and a very fast motherboard.

    Finally, I decided to check if my AVG antivirus or IOBit Malware Fighter software is interfering and I disabled them temporarily. I restarted and then turned off these programs and then opens Firefox. It was as usual, 17.0.1 version not updated. I went to help, on Firefox, click Find updates. Downloading updates, invited to restart Firefox, and after closing Firefox, I got the window that says that he was installing the updates, for the first time for an attempt to update to version 17 or 18. He installed the updates and restarted in fact without any problems.

    I was about to turn off all of my Add-ons for the next test. I never had to disable my AVG or IOBit before and they are the latest versions, too. AVG is the same version that allowed the update to v. 16 before. If something is different both Firefox 17 and 18, that it will not allow updates with AVG in force (or possibly IOBit Malware Fighter).

  • When I get an email, according to windowsmail with attachments, I can't file attachments by using the file command menu

    original title: impossible to file attachments in mail

    Hello; I'm with family Vista premium and windows mail as a messaging system. I was with IE8, and now I've migrated to IE9.

    When I get an email, under windowsmail with attachments, I can't file attachments by using the file command menu. This option is blocked. Under windows mail, I went to tools, options, security and made sure that: Let not the attachments which are unsecured... box be deselected.

    IE9 is certainly the culprit and there is more questions. I know that some MVPs have contacted their MS threads about it and even received no answer.

    My guess is that MS will not address this issue. Do not forget that the development team of Windows Mail is dissolved by the MS in June 2006. (Yes, while Vista was still in beta). I seriously doubt they care.

  • Issue while loading data using the file Rules Essbase

    Hi all

    I am facing problem while loading data using the Rules file. In the rules file, I rejected several members in two areas (two dimensions). Now if I load the data using the rules file I'm getting errors for all members in the dataload.err file. If I reject mutiple members of a single field, the data load without settling errors in the dataload.err file.

    I want to know how rmany members of several fields of ejection for loading data using the file Rules Essbase? Is it possible?
