  My doubts are (for linux x86_x64):
  "Unbreakable Enterprise Kernel for Linux" is really mandatory for RHEL 5.5 and Oracle Grid Infrastructure or is it possible to use RHEL 5.5 with RHEL kernel.
  Oracle RAC Database 11 g 2 is supported on RHEL 5.5 with RHEL kernel supported?
  
  Thank you

  Pavang is right.

  I opened a SR and Oracle Support they confirmed she RHEL 5.5 with RHEL kernel is supported (minimal support). but Oracle is highly recommend to deploy the nucleus of the unbreakable Company Oracle.

  Some reasons for their recommendations:
  http://public-yum.Oracle.com/
  The core Oracle Unbreakable Enterprise for Linux is the standard kernel used with Oracle products. The build
  and QA Oracle database systems and other Oracle products use the core of Oracle Unbreakable company
  for Linux exclusively. The core Oracle Unbreakable Enterprise for Linux is also the kernel used in Oracle
  Exadata and Oracle Exalogic systems. Oracle Unbreakable Enterprise Kernel for Linux is used in all benchmarks
  tests on Linux in which Oracle participates, as well as in the setup of valid Oracle for x 86-64.

  Thank you.

• What is the difference between Oracle RAC and Oracle Clusterware?

  Hi all, it's maybe a stupid question, but I read the documentation and still do not understand what is the difference between RAC and Clusterware.
  Can someone explain it to me?
  
  Thanks in advance!

  ACR is part of database software Oracle database option should be the database mode cluster; See http://download.oracle.com/docs/cd/E11882_01/server.112/e16508/glossary.htm#CNCPT2076.

  Clusterware is a separate required to run the Oracle database in cluster mode: you can use Oracle Clusterware without Oracle database, but you cannot use Oracle Database with the option CARS without Oracle Clusterware.
  See http://download.oracle.com/docs/cd/E11882_01/rac.112/e16794/intro.htm#BABCHEEE.

  Hello

  I guess I was not clear... There is no specific document. You are indeed documenting many RPMs that make up a GNU/Linux management appliance. There no such reference even for GNU/Linux then why do you not wait for the ESX management unit which runs GNU/Linux?

  Each rpm has own documentation. Each sysconfig file and / etc is related to a rpm of one kind or another. My example of sendmail is a concrete example.

  Note that this is JUST the contents of a virtual machine for GNU/Linux. It's the void device management system not really ESX.

  Remember that Linux is the kernel, not the ecosystem surrounding it, which is the part of GNU. For Linux, there are several references that are very good... Linux kernel in a Nutshell, understanding the Linux kernel, understand the workings of network Linux

  For each component of the GNU, there are scads of documentation on the web. It will be RPM by RPM. The most complete reference for the part of GNU GNU/Linux are big sellers like RedHat, Suse, Ubuntu, etc.. I would go to the RedHat online documentation, as is the closest to that VMware uses.

  Also note that what you find that GNU/Linux for ESX management machinery will be different in the unit of management for ESXi Posix.

• How to check the version installed oracle RAC

  Hi all
  
  Y at - it a command or file to the version installed oracle RAC. I saw some post to the topic to connect to sqlplus and access the v version $ but I need a command that does not require database either upward. I mean, even if the database is down, I should be able to know the version of oracle RAC.
  
  Thank you very much for your help in advance,

  I must admit that I never installed Oracle without the GUI, but I strongly think it is works, no matter how you installed Oracle. opatch is one of the essential tools that comprise an oracle installation, without him you wouldn't be able to fix your installation.

• How Oracle Clusterware Oracle RAC and 3rd-party Clustering with them

  I have some questions on how Oracle, Oracle RAC and 3^rd party clustering CLusterware fit between them.

  Q1. My understanding is that the Infrastructure Grid Oracle Clusterware is Oracle's Clustering solution that allows applications to cluster? that is, it is a general clusterware solution to compete with those already on the market. Is this correct?

  Q2. So why CARS is necessary for the Oracle cluster databases? An Oracle database is not just considered one application like any other? So why can not just use you GI / Clusterware to gather what you would do for any other application? Why so you need RAC to the Clusterware Summit?

  Q3. Is it is possible to combine an Oracle database using 3^rd party of clustering and not use Oracle Clusterware and CARS at all that is can you say cluster, an Oracle database using say Sun Clusters, Clustering AIX or Linux native same clustering?

  Q4. If the RAC is purely for Oracle Cluster databases - what is with the title "Real Application Clusters"? What's real on this subject?, what to ask?

  Q5. I also read that RAC can use 3^rd party of clustering. However if you decide that this is the case, then you need to install Oracle Clusterware when even (I think for interconnection must be created to allow the merger with Cache between Instances of node?).

  Is this the case?  If yes why never bore you with 3^rd party clusters? -Since you will have to install Oracle Clustering anyway - and I probably have to license (all I can think about is the scenario that you already have a cluster of 3^rd party in place and you decide that you need to use the same material for a database cluster)?

  All wisdom greatly appreciated,

  Jim

  Yes, with 10g, you had to use the CRS, and with 11g, to use the GI.  For 9i RAC, you would use Verits Cluster and Sun Cluster or anything else.

  11g RAC to GI.  As above, you can use clusterware extra if needed.  I gave the example above where to a 10g RAC we used the CRS to the cluster database/listener/vip and allowing groups of volume and filesystem in HACMP cluster.  File systems were not shared, but could switch to another node failure node, who has been treated by HACMP.  The volume of the groups containing the raw devices were shared volume groups.  For 11g, I never used extra clusterware on top of CRS and have always used ASM which is part of the GI.

  The application provider only certified database to run on 10g on AIX with raw devices.  What is strange about that?  It would be unusual that you probably expect to use ASM instead of raw devices, but it is what it is.

  See the following Note of Oracle for more information: using Oracle Clusterware with vendor Clusterware FAQ (Doc ID 332257.1)

  It is perhaps easier to explain if you can explain what problem you are trying to solve?

  Hello

  HACMP is vendor clusterware (technology IBM) it is cluster high availability Cluster Multi Processing. During the installation of Oracle RAC it must installed on top of the vendor clusterware.

  HACMP comes in the room when you use a logical volume gross and it must be managed by HACMP.

  Since the 10g, it is not mandatory to use HACMP so that you can choose not to use it and let the Oracle to manage all the services cluster

  Hope this helps
