ASM Configuration prior to installation of Network Infrastructure
Hello
I want to install a network infrastructure for a stand-alone server 12 c on a virtual machine, it is a first installation, no front installed Oracle software.
My problem is on the third screen of the Installer (create the ASM disk group), I can't view the ASM disks and the preinstallation process is not clear to me.
I defined the systems files/U02, /u03, /u04 and /u05 with the oradata and recovery_area directories (oracle: oinstall) for each /u0 * and I want to use them with the DSO.
I installed the oracleasm-support and oracleasmlib packages, I executed oracleasm configure with parameters of dba (Group) and oracle (user).
Question 1: I need to run init oracleasm (with default settings) to create the/dev/oracleasm before launching the installer of the grid?
Question 2: I run oracleasm createdisk before launching the installer of the grid?
Question 3: What is the proper syntax for the parameter createdisk command 2nd (/ u02, / dev/map/VG_ORA-lv_u02, / u02/oradata,...)?
Thank you
Daniel
Hi Daniel,.
There is a lot of confusion here.
ASM is just another Manager file system offering you a more simple and flexible LUN management. Basically, you choose to transfer your database in the file system (/ u01, / U02, oradata, recovery_area) OR if you choose to use the DSO. If you choose to use the DSO, you must create the ASM diskgroup before installing your database. As you mentioned as part of the installation you need to 'discover' the ASM disks and create the first disk group where the DSO Server settings file is kept.
To do this you have need of screening to the ASM one or more LUNS that are owner by user oracle. Lets assume you want to create two groups of DATA and FRA disks and make your databsae to use. If you use a virtual machine, you need to create more than two disks. Once you do that you have to idetify them, they will be discovered under/dev/sdX. On the same, you must create a partition to fill the entire disc (fdisk/dev/sdX, n for new, p for primary school, 1 to the first disk, and then you press ENTER twice, finally w for write). Finally, you need to make the new owner devides/dev/sdX1 by oracle (oracle: oinstall/dev/sdX1 chown).
At this point, you should go back to the installer and change the string of disc asm/dev/SD * 1, this will make ASM read all the first partition of all the/dev/disks in sd. Then, you select the disks that you want to use for the default disk group. This can be repeated for the rest of the disk group you want to create using asmca (asm Setup Wizard) or simply using SQL command.
oracleasm is the ASMLib that was used as a layer of abstraction to make sure that the device files will always have the correct permissions. Nowadays, making using udev as follows:
Cat > /etc/udev/rules.d/99-oracle-asm.rules
SUBSYSTEM is 'block', KERNEL is "sdf1", NAME = "asm_data01_disk1", OWNER: 'oracle', GROUP =: = 'dba', MODE: = "660".
When you start this matches the device to/dev/sdf1 file and create an other device file under/dev/asm_data01_disk1 with permissions oracle: dba
Hope this helps, but it's just too much information.
Kind regards

Installation of network infrastructure for CARS using UDEV fail
Hi experts,
I want to install the RAC for the test using UDEV, VirtualBox and Linux 64 bit 5.8.
I can't installing grid Infrastructure (ASM). In step 5 of 9 - create ASM, Setup disk group displayed not all disks to create ASM diskgroup.

Install a network infrastructure for a single-node Windows Server cluster
Hello
Can you suggest me how to install a single-node RAC Oracle 11 g on a Windows Server 2008 x 64-bit? It's for testing purposes and I do not need two nodes. I know that Linux is better, but my company uses only Windows servers. Our former consultant has been able to do, but doesn't tell us how to, this server has been lost.
I know that to install the first grid Infrastructure. Run the installation program "Oracle Grid Infrastructure", I could install a "Grid Infrastructure for a stand-alone server" successfully. But this Grill is not a RAC database. When you try to install the database software, which is available to me to install only "single-instance database", not "Real Application Cluster installation".
Run the installation program "Oracle Grid Infrastructure", I have tried select the option:
'Install and configure a Cluster Network Infrastructure'-> typical Installation:
The name of the SCAN: SRVORAC-cluster
Validation of ANALYSIS information
INS-40922 SCAN invalid name - insoluble in IP address.
Is it possible to install a network infrastructure for a cluster to a single node or a node on Windows Server?
Published by: user521219 on January 30, 2012 12:46Hello
You probably misunderstanding about single-node RAC. This feature didn't need that you have only one physical machine in a RAC, this in fact means that in a CCR environment (2 or more nodes), you can run your database on a single node (single instance), and then later you can move this single instance to another node of the RAC (so that you can make some fixes on this node making your database available all the time). It also has a few other advantages, see below.http://www.Oracle.com/technetwork/database/clustering/overview/UG-raconenode-2009-130760.PDF

Problem on installing network infrastructure - SCAN name and IP addresses
People,
Hello.
I was installing RAC Oracle Database 11 g 2 system with 2 Virtual Machines (rac1 and rac2) in 3 VMPlayer.
I set up ASM. Now, I want to install the network infrastructure for rac1 and rac2 using runInstaller.
I type in 'rac-cluster' in the name of SCANNING box in the wizard.
According to my understanding, SCAN IP addresses are used to connect to the shared database. 3 IPs SCAN for shared rac1, rac2 and DB are automatically assigned during the installation of the network infrastructure. I need not specify IP SCAN 3 addresses in the file/etc/hosts.
But when installing on step 3 of 8 grid infrastructure, the wizard appear this error message:
"Invalid name SCAN - insoluble in IP address. SCAN name: rac-cluster cannot be resolved. »
Any folk that understand how to solve the problem above (name SCAN & IPs) on step 3 of 8?
Thank you.Hello
YES requires the SCAN name. SCAN name is the host name.
Without DNS, you can set the name of the SCAN on the file/etc/hosts.The hosts file can resolve the IP address only 1 for 1 hostname.
Specify a SCAN name on your file hosts of two nodes (same IP address).
And only one resource SCAN VIP will be created.ex.
$ grep rac-cluster/etc/hosts
192.168.1.100 rac-cluster
* the two node addressAnd specify 'rac-cluster' on the name SCAN of YES.
Good luck.

Unknown to router in the Network Infrastructure
Hello
There is a unknown router which is not mine not appearing in the Network Infrastructure.
I understand why it show up under available wireless networks. But not the network infrastructure.
I have not connected to it, is not my router, and it is not there. It is a little disconcerting, to say the least.
Here is a screenshot:
http://www.imagebam.com/image/2ed1ec73539535

WNR1000v2 isn't.
Is this a security risk? Why is this, and how do I get rid of him?
Thank you.
(Essentially the same problem as this):
OK so I would like to know what criteria determines why a router is listed in the network infrastructure... and how to get rid of him?
Why is windows 7 this? It makes no sense at all...
Can't really answer. I can only say that turning on the Details view for the page shows that the alien router isn't listed in my network location. A network infrastructure device is that in theory I 'could' connect to research a little further into the router configs (properties because it gives model, series No, MAC address and unique identifier #) indicates that the owner has set up to use WiFi Protected Setup to allow wireless devices to connect (requiring a fixed number of pine). So, if I had the PIN to the router, I was able to connect to its network. Maybe that's why it appears. If your mystery router is configured in the same way, this could be a further indication as to why these routers being listed in the title of the Network Infrastructure while all other neighboring routers are not.

WNR2000 listed in network infrastructure, but why?
under network infrastructure is wrt54gs and wnr2000 lists. I use the linksys wrt54g, but the Netgear wnr2000 shouldn't be there. About netgear anywhere on my network when I try to configure it wants a rod of 8 numbers that obviously don't have. This is one of my neighbors hanging in my wireless phone? If so, how can I block the?
Hi Travyj,
Your network is simply show other networks available in the range. Nobody's trying to access your network resources.
We recommend that you first of all to you cross check whether all incoming connections are allowed on your network connections. To do this, try the following steps.
1. open network connections by clicking the Start button, clicking Control Panel, clicking Network and Internet, click Network and sharing Center then click on manage network connections.
2. uncheck the 'Accept incoming connection' to turn it off.
3. apply the changes and check the difference.

I'm looking to see what situation is better regarding my ASM configuration and what would the dispatch behavior. I use OEL 5 Update 2 x 86-64 and 11 GR 2 Oracle database and 11 GR 2 ASM.
Configuration 1
4 physical HD RAID 5
4 100 GB LUN
1 disc ASM for each LUN
2 (DATA and FRA) ASM disk groups
2 ASM disks by ASM disk group
Installer 2
4 physical HD RAID 5
2 200 GB LUN
1 disc ASM for each LUN
2 (DATA and FRA) ASM disk groups
1 disc ASM ASM disk group
Question 1:
In configuration 1, given that the ASM disks for group to data disks are on the same physical disks, would be this important cause of hotspots. I understand it undoubttedly would claim.
Question 2:
2 installation, ASM would not fail because it cannot scratched in this configuration with only one disk of the DSO. In other words, the ASM would work but simply tape even if the physical HD underscore aren't be scratched by RAID 5.
Question 3:
What Setup is better in terms of availability and performance?
Thank you.Please see my previous response on hardware RAID, you must use. It depends on your fault tolerance acceptable device, compared to considerations of capacity and performance, also depending on your storage controller.
The configuration you have provided, I suggest to create 4 readers (LUN LUN) of the same size on your RAID storage space. Then create a large partition on all 4 discs and use for example Linux ASMLib to assign these scores to the DSO. ASM to create a diskgroup (+ DATA) using the 4 ASM disks with external redundancy.
I would not throw the discussion about the location of the ASM parameter in this thread. It's a completely different subject.

I got a modem Comcast/Xfinity upgrade. Xfinity X 1 modem/router is compatible with the Airport Extreme? How it should be configured to maintain my wireless network?
Whenever you change the modem or modem/router on a network, AirPort Extreme will be reset to the default settings and then set it up again to work properly with the new modem. For this he would be...
Turn on AirPort Extreme for a few minutes... If it is not already turned on
Hold in the reset button on the back of the AirPort Extreme for 7-8 seconds, then release it.
Allow a minute for the AirPort Extreme restart to a slow, flashing amber light status
Make sure that an Ethernet cable connects to one of the four LAN <-->Ethernet ports on the modem/router on port WAN "O" on AirPort Extreme
To start the Setup program, click the WiFi icon at the top of the screen on your Mac and are looking for a list of the new AirPort base station
Just below that, click directly on the AirPort Extreme and then follow the prompts for configuration "Wizard".
When you configure AirPort Extreme once again, you can use the same wireless network name and the same password that you used with AirPort Extreme with the 'old' modem, if you wish, or use a new wireless network name and password

Why do they detect Router 1 neighbor in my WIFI network infrastructure
Why do they detect Router 1 neighbor in my WIFI network infrastructure?
Hi Noel,
I detect 4 myself. This is because your WIFI is set to detect the transmissions and this router is powerful enough to join and be detected. In theory, if it is not secure you can hack illegally their connection - but it is a way of a street. Just because you see does not mean them they can see yours, nor that this means that they have access to your system.
Now, if your router is not secure (and you certainly must do if it is not already the case since if you capture the transmissions there is a chance they can capture your and possibly access to your network - as someone just driving by in a car or on foot near your home with a WIFI enabled computer) so it's a different story but then there are different and would not appear as an option connection, but rather as someone literally connected.
As you were not very specific, I assume you mean the first paragraph. If you really mean the second, then please set your router immediately. If it is already fixed, then change all passwords and see if that solves the problem. If this isn't the case, then back and we say more and we will refer you to people who can help. Please indicate your version of Windows, your network setup, and exactly what you mean (specifically, where exactly are detect you).
I hope this helps.
Good luck!

-In the seat, I have a cisco ASA 5510
-The requeriments of device of the site data center (not yet acquired) are:
-> The network interfaces three to form a demilitarized zone. a single interface would be connected to WAN, other would be connected to the DMZ and the last would be connected to the internal LAN.
-> This device must allow connections for mobile users.
-> A connection VPN site-to-site must be authorized from Headquarters.
-Requeriments of the security are:
-> VPN, connections are allowed with the direction to the DMZ.
--> Traffic between the internal machine to DMZ and LAN ports are allowed.
--> Traffic from the internet to ports 80/443 of a DMZ machine is allowed.
-High availability data center website.
For now, I'm worrying about the site to site VPN connection:
A single point to point VPN with Gre over IPSEC, the use of static routing would be a good solution?
Someone told me that the ASA 5520 device in the data center site is the best option, what is your opinion about that?
I have seen software SDM to configure the device, is sufficient to set up the device with the requeriments or CLI is better?
Thank you for your comments!
If you use the gre with static route you can do or any dynamic routing you can make up the tunnel always
with shoud ipsec static route only point the to the public ip address to visit remote as of the next hop and the tunnel will come when United Nations interesting traffic matching ACL ACL crypto plan
STP with HSRP work in traffic going from L2 to L3, you must ensure that the HSRP active device is the root bridge as well
Good luck
