  Hi Experts,

  1 can you please let me know why we need to set up under IP addresses for the RAC configuration and what is the role that each plays?

  -Public

  Configured before installation for each node and can be resolved at this node before installing.
  Role:
  Enable Virtual/SCAN configuration/communication between the nodes in the cluster. Do not start the Clusterware without public IP Interface/address.
  Virtual/SCAN will work as an alias IP on the public Interface on the Public network.

  -Private or interconnection

  Configured before installation, but on a separate private network, with its own subnet, which is not resolved except by other nodes in the cluster member
  Role:
  Clusterware uses for cluster synchronization (network heartbeat) interconnection and communication of demon among the nodes in the cluster.
  RAC uses the interconnect for cache fusion (UDP) and inter-process communication (TCP).
  Cache Fusion is the remote Oracle buffers, shared memory mapping between the caches of the members of the cluster nodes.

  -Virtual

  Configured before installation for each node, but not currently in use. IP, VIP and treats public SCAN addresses than any other addresses on the same subnet.
  Role:
  The goal is the availability of the applications. If add or remove nodes as your remove VIP client config (with SCAN, it is not necessary)
  When a node fails, the VIP associated with it is automatically failed over to another node.
  Without using VIPs or FAN, clients connected to a node who died often wait a TCP timeout (which can be up to 10 min) before getting an error.
  So, you don't have really a good HA solution without using VIPs and FAN. The best way to use the FAN is to use a client integrated with fast connection failover (FCF) such as JDBC, OCI, or ODP.NET.

  -SCAN

  Three static IP addresses that are configured on the server (DNS) domain names prior to installation so that the three IP addresses are associated with the name provided as the SCAN, and all three addresses are returned in random order by the DNS to the applicant
  Configured prior to installation in the DNS to resolve the addresses that are not currently in use. Addresses on the same subnet than all other IP addresses, addresses VIP and public SCAN
  Role:
  The goal is the availability of the applications before clients establish communication with CARS and make the whole of the Cluster completely transparent.
  IP SCANNER is a new 'layer' (oracle) with high availability network that allows to modify the characteristics of your cluster (IE add/remove nodes) without having to change the configuration in their concept of customers 'grid '.
  >

  2. What is the relationship between IP SCAN and virtual IPs?

  IP SCANNER is used to receive new connection requests and redirects to the VIP IP.
  The virtual IP address sets and allow failover of connections after connection is established.

  When the client requests a connection, Oracle Client 11 GR 2 find for IP addresses and create a list of all IP SCAN available for this host-scan, the first attempt to connect to RAC uses one of the available SCAN IP addresses.
  The listener ANALYSIS will receive this connection and re - direct to one of the available using LOCAL_LISTENER nodes from that time the connection is made by using the virtual IP (VIP).

  All SCAN/VIP must be resolved by the DNS.

  The customer knows that there is only the Hostname SCAN, which is configured in the connection string.
  Once the connection is requested Oracle Clusterware redirects the connection to one of the VIP host name must be resolved by the DNS.

• Oracle 11 g 2 RAC does support IP dynamic?

  Oracle 11 GR 2 RAC does support dynamic IP, or does it only support static IP?

  For IP addresses? 11 GR 2, you will have the following:

  public host name

  The private host IP

  VIP listener

  SCAN VIP

  Your private host names should not be dynamic IPs because no one should ever use. Interconnecting them will use however. Keep these static to save you headaches.

  Similarly, the public hostname should not be accessed by anyone other than information TECHNOLOGY personnel who need to do some work on the server.

  Applications should use the VIP or SCAN VIP listener. I guess that these can be dynamic IP addresses. However, with today's networks, there is little need to do. We use DHCP to all of our IP addresses, but then bind us the registration of the contract so that DHCP will always return the same IP address. Forgive me, but I don't remember the network for this term.

  See you soon,.

• Changed IP to use binding and now I can't ping my rac-scan address.

  With the help of Oracle Linux 6.3 and 11.2.0.3 Oracle Rac.
  
  My database and RAC cluster worked very well and I could ping my name "rac-scan" that is configured to resolve in DNS from a specific IP address.
  
  I needed to set up a network on all network adapters binding to ensure failover and balancing in the network layer.
  
  I got the liaison work and ping/ssh I could before. Rac-scan ping no longer works.
  
  I guess that Oracle has somewhere from eth0 instead of bond0 rac-CT?

  Hello

  RTFM. The section how to change addresses network and interfaces is in the doc:

  I created 2 VMs in ESX5 which worked fine before the installation of a cluster. I created disks shared between virtual machines and when I install the cluster then during installation I confronted error below.

  YES-25031. some of the assistants of configuration failed. When I have connected on 2nd machine and click connect to the Local network , then the machine is completely hung. When I killed the connection to the Local network via the Task Manager or restart the system works well, but when I click on LAN then faced again as I don't have this problem Oracle Virtual Box.

• Observed only one IP for 11 GR 2 RAC SCAN, all the problems?

  Hello

  In one of our customers environment I've observed that they only used a single IP for RAC 11 GR 2 ANALYSIS, but wherever I know Oracle recommended to use 3 IPs to SCAN.

  There will be problems with the single use IP Scan instead of three?

  Please suggest.

  Thank you

  Mahi

  A single SCAN VIP (with the SCANL) would be necessary in fact to get the job of RAC 11.2. Three are recommended for environments where the only VIP SCAN isn't able to handle the workload. So there is nothing wrong in this moment with your configuration. It seems, you use a configuration of DNS to resolve the name SCAN and your guys N/W used a single IP address only to the name of SCANNING resolution.

• Reinstallation of Oracle 11 g 2 RAC grid problem - ASM disk group

  People,
  
  Hello.
  
  I want to install Oracle 11 g RAC 2 with 2 Virtual Machines (rac1 and rac2 which BONES are Oracle Linux 5.6) in VMPlayer.
  
  I was installing Infrastructure of grid using runInstaller in the first rac1 VM from step 1 to step 9/10.
  
  On 9/10 in the wizard step, by chance, I touch the mouse, and the wizard disappeared.
  
  The grid in the 2 VMs installation directory is the same: / u01
  
  I have to make sure that everything is correct, delete the directory/U01 to 2 virtual machines and install again the grid in rac1.
  
  I realized that this is not the right way to remove/U01. The right way is to follow the tutorial
  http://docs.Oracle.com/CD/E11882_01/install.112/e22489/rem_orcl.htm#CBHEFHAC
  
  But I have deleted/U01 and must correct one by one. I reinstall the grid and get the error message in step 5 of 9 as follows:
  
  [INS - 30516] Please specify unique disk groups.
  [INS-3050] ASM disk group empty.
  Cause - the installer has detected the name of Group of disk already exists on the system.
  Action - specify the different disk group.
  
  In the wizard, the old disk group name is 'DATA' and his candidate records (5 ASMDISKs) are gone. I try to use another name "DATA2", but no ASMDISKs are "candidate records. For "All discs", it is impossible to select all ASMDISKs.
  
  I want to use the same disk group ASM 'DATA' and do not want to create a new disk group.
  
  My question is:
  
  How to make previous ASM disks and his group of 'DATA' therefore "Candidate records" who can use again?
  
  
  Thank you.

  Hello
  If you use oracleasm, then rebuild again asm disks.

  Hello

  Mount the DVD media and check the server / directory.

  # cd //Server
  # ls libaio-devel-0.3.106*
  # ls sysstat-7.0.2*
  # ls unixODBC-devel-2.2.11*
  

  I could find in the "Enterprise-R5-U6-Server-x86_64-dvd.iso" of the ISO file.
  I could find also all 3 files in Oracle Enterprise Linux 5.5 x 86 32-bit CD-ROM media #3.
  (from the "Enterprise-R5-U5-Server-i386-disc3.iso" file.)

  And type the rpm command to install.

  Configure the results of udev in the drives mapped to the names of persistent drive for example. / dev/iSCSI/arpl1/part1
  always when I enter the name of the raw device that I created I get the following error. Help, please

  It seems that you should do the following:

  Verify the existence of udev mapping rule file /etc/udev/rules.d/60-raw.rules brute
  On HR/EL5, gross udev mapping rule file /etc/udev/rules.d/60-raw.rules must exist by default as part of the util-linux package, for example:

  # ls /etc/udev/rules.d/60-raw.rules
  /etc/udev/rules.d/60-raw.rules
  

  Create a custom gross udev mapping rules file, /etc/udev/rules.d/61-oracleraw.rules say, for example:

  # touch /etc/udev/rules.d/61-oracleraw.rules
  

  3B. Add raw udev binding rules to the /etc/udev/rules.d/61-oracleraw.rules file
  Add the binding rules gross udev in the etc/udev/rules.d/61-oracleraw.rules file, for example:

  # cat /etc/udev/rules.d/61-oracleraw.rules
  # Raw bind to Oracle Clusterware devices
  ACTION=="add", KERNEL=="sd*", PROGRAM=="/sbin/scsi_id", RESULT=="360a98000686f6959684a453333524174", RUN+="/bin/raw /dev/raw/raw1 %N"
  ACTION=="add", KERNEL=="sd*", PROGRAM=="/sbin/scsi_id", RESULT=="360a98000686f6959684a453333524179", RUN+="/bin/raw /dev/raw/raw2 %N"
  

  If switch to RHEL5/OEL5 since an earlier version of Linux that has pressed persistent raw device bindings in the/etc/sysconfig/rawdevices file, the following script can serve as a basis to generate your RHEL5/OEL5 of the udev rules. Note that the script does not factor device name persistence.

  #!/bin/bash
  grep -v "^ *#" /etc/sysconfig/rawdevices | grep -v "^$" | while read dev major minor ; do
  if [ -z "$minor" ]; then
  echo "ACTION==\"add\", KERNEL==\"${major##/dev/}\", RUN+=\"/bin/raw $dev %N\""
  else
  echo "ACTION==\"add\", ENV{MAJOR}==\"$major\", ENV{MINOR}==\"$minor\", RUN+=\"/bin/raw $dev %M %m\""
  fi
  done
  

• How to cancel the encryption SSL on ACE after scan IPS

  Hello

  A query on the SSL termination. This is the logical path,

  The traffic encrypted hits the router-> hits the ASA IPS-> and then hits the VIP for balancing by ACE.

  Encrypted SSL traffic must end on ACE load balancing. However, the IPS analysis cannot be performed on a decrypted traffic.

  How can we re - encrypt traffic to complete on the load balancer. Or is it a bad idea because of performance issues?

  Kind regards.

  Yes, your understanding is on-site. Both IPS/CSC need traffic decrypted to do something meaningful.

  Concerning
