How to setup rac scan on OEL6 on virtualbox

I am trying to setup RAC on a 2 node cluster. i am trying to setup rac scan.
i have 2 ip address
192.168.8.1 - public node 1
192.168.8.2 - public node 2
192.168.1.1 - private node 1
192.168.1.2 - private node 2
VIP Ipaddress
192.168.8.6
192.168.8.7
192.168.8.8
the scan ip's are
192.168.8.3
192.168.8.4
192.168.8.5
NOTE: i have an active directory network in house that uses the public ip's subnet above. which also act as my DNS servers. The public ip's are connected to the internet. so all my linux boxes are browsing
i have added all the ip's to my host file. and installed dnsmasq. and followed the steps on oracle-base. i have two nic on virtualbox. one bridged to the host system and acting as my public ip (192.168.8.0) while the other is an internal network for the private network(192.168.1.0)
ORACLE-BASE - Dnsmasq : For Simple DNS Configurations

Your /etc/hosts file should be like:
# public
192.168.8.1     node1
192.168.8.2     node2
# private
192.168.1.1     node1-priv
192.168.1.2     node2-priv
# VIP Ipaddress
192.168.8.11     node1-vip
192.168.8.12     node2-vip
# scan ip's are
192.168.8.3     cluster-scan
It is better to define 2 NICs for each VM: 1 for public networking and 1 for private.

How to setup network scanning

Hi,
Recently purchased a 21.5" iMac - cant get it to scan using the network scanner in my office - any sugestions?

Hi bmw47335
Welcome to the forum.
This is in the wrong forum (this is Pages) and probably best answered in the OSX (Snow Leopard) forum.
However with network scanners it depends how it is being shared from what, a Mac or PC. Also whether you have the appropriate drivers or Twain, for the scanner, actually on your machine.
You should also be able to get telephone support directly from Apple as part of your included installation support, even better if you purchased AppleCare, always a good idea.

How to setup rac

Dear friends
Hello
I m setting up rac on 2 database , i have 2 questions:
1- Can i set up its on 2 different hardware , one : HP8420 / HPUX , tow : HP4440 / HPUX
(one database on first machine and the other database on second machine)
2- Can i set up its on different operation system , i.e one of the on HPUX and
other on WINDOWS NT .
Regard
A.Jafari

Hi Jafari,
On the same cluster, you can't have different Operating Systems. But RAC are available for several Operating Systems like Linux, HP-UX, Solaris, Windows and others.
Rac uses one database managed by more the one instances. You can have more than one database runing on RAC systems and this signify more instances runing at same node, like stand alone environment, if you has more than one database on same machine you must run more than one Oracle instances.
The RAC architecture is different, but not too much.

How to setup private network in oracle rac

Hi all,
Iam trying to setup oracle 2-NODE RAC ,
now i stuck in setup private network..
how to setup private network, what i have to do for that.
please help us provide step by step process

The loop is nothing but a network cable connecting two nodes on same port with a private IP address (something like 10.0.01 and 10.0.0.2) which is not accessible by any other machine in the network (except 2 nodes obviously ).
Note that cross over cables are not supported for the Cluster Interconnect. And cross over cables limit the cluster to only 2 nodes, which may not be enough for many RAC deployments.
Cheers,
Brian

Changed the IP to use a bond and now I can't ping my rac-scan address.

Using Oracle Linux 6.3 and 11.2.0.3 Oracle Rac.
My Database and Clustered RAC were working fine and I could ping my "rac-scan" name that is setup to resolve in DNS for a specific IP address.
I needed to setup a network bond on all the network cards to ensure failover and load balancing at the network layer.
I got the bond working and ping/ssh as I could before. Pinging rac-scan no longer works.
I imagine Oracle has somewhere the rac-scan coming from eth0 instead of bond0?

[root@oracleA bin]# ./oifcfg getif -global
eth5 10.16.11.0 global cluster_interconnect
eth0 10.255.16.0 global public
eth0 is what I changed to be the bond0 combining eth0 and eth1(which was unused).
Is there a way to change eth0 to bond0? Do you know how if or how I could?
Also the address given shows the network address not the actual node ip at the end (10.255.16.101) but I think that is normal from your example.

How to setup the Airport Extreme for PSP?

Can anyone tell me how to setup the Airport Extreme for PSP? I have been searching the Discussions but none of the posting seems to explain detail enough. A step by step guide would be very appreciated. Thanks.
PowerBook G4 Mac OS X (10.4.3)

Sorry, I forgot to mention a few points:
1) I don't have the Airport Extreme base station;
2) My PowerBook is connect to the internet thru wired connection with the Built-in Ethernet;
3) The Airport is turned on, but my PSP's scan cannot locate the PowerBook at all (while it find someone else's network)
So, I wonder if I can just connect my PSP to the built-in Airport in the PowerBook directly. So that I can have internet access on my PSP.

How to setup the fax function for a AOI device

I read in several post on this forum that people get full print/scan/FAX functionality for the supported printers.
In my case, I have a HP Photosmart C7280, which is full supported using the C7200 series drivers, including a FAX driver.
Now, I add a printer in the 'Print & Fax' panel, and right away my printer shows up for bonjour. It finds automatically the correct driver, and works like a charm for printing and scanning, but... No Faxing whatsoever. Also no 'second' printer shows up, with 'kind' HP Fax, as several posts sugguest. Not after a few seconds, not after minutes. Using the 'Fax Devices' tab also doesn't show me any HP Fax device.
So basically my question is: How do I setup the fax functionality in SL with my printer?
Yes, it is connected over network, and the fax functions did work perfect over network with the 10.5 drivers from HP. Am I running into SL limitations? Does SL fax-drivers still support the (not optional, but default builtin) network functions of the C7280? Or... Am I just a noob that just can't find out how the setup a Fax device the obvious way
Thanks
- C

Hello mscheidell,
Yes, I was aware of the 'two' 7200 series drivers, but thank you for checking with me.
Okay, now how did you 'add' your fax device for your printer? Did it show up a second version of your printer in the 'Add printer' box, with type FAX? Or did you just add the same 'found' printer again, but the second time with the FAX printer drivers (manual selected)?
Right now, I only get one entry when I try to add my printer into SL: It find the Photosmart C7200 series with 'kind' Bonjour. That's the only thing that will show up in my 'found' printers, even after waiting a few minutes. People in these discussions are telling me there should show up a second 'found' printer with 'Kind' HP-Fax, but that just won't happen for me.
I also tried to add the same found 'bonjour' printer again, and select manually the 'Photosmart C7200 series - fax' driver. SL tells me then there is already a print queue for that printer, but I tell SL to add this printer anyway. Then I have this C7200 series Fax device in my printing list. Using this driver seems to work fine, I can fill in fax recipients, but hitting the print button, caused the C7200 to spit out it's complete papertray, printed with bogus ascii signs only on the first lines of the page, instead of really faxing that document. So I concluded that this was not the right way to get the fax working....
Thanks for all the help again.

How to setup a UDP port forward range

Hi,
We are trying to figure out how to setup UDP port forward range. This is the configuration that we are using.
ip nat pool voip-rtp 10.10.10.3 10.10.10.3 netmask 255.255.255.0 type rotary
ip nat inside destination list 114 pool voip-rtp
access-list 114 permit udp any any range 16384 32767
Where 10.10.10.3 is the host I want to forward the ports 16384 to 32767 to.
This is not working. We use a similar set of commands for TCP range forwarding which work perfecting. Can anyone advise of the correct way to port forward a UDP range.
Damien

thanks for the suggestion.
I tried the same , but still the udp port 514 is not available. when i run nmap tool to scan the ports, the udp port 514 is not available to the external world and hence the syslog msgs i send to tat port is not being received. kindly help me out.
thanks again!!

How to setup wireless printing with AirPort Express?

Hey, I just bought a AirPort Express today and I can't figure out how to setup the usb wireless printing. Could someone explain in detail on how to do this? Thanks-Michael
I have a Windows 7 64-bit PC and a Hp Deskjet F380 USB printer.

Download the install Bonjour Print Services for Windows v2.0.2
Run the program. Hopefully, your printer will be recognized.
If it is, "install" the printer and try to print.
Keep in mind that if you have an All-in-One type of device, that only the print function will be supported.
Advanced features like copy, scan, maintenance, etc are not supported. You will need to connect the All-in-One directly to your PC if you need those services.
