• Oracle 10g RAC and Unix * question rlogin *.

  I supports several bases RAC 10 g running on servers pSeries IBM using AIX 5.3. Our data base and the clusterware indicated 10.2.0.3 10.2.0.4.
  
  I understand that user equivalence and rsh/ssh must be enabled so that the environment RAC and clusterware to connect across all the cluster nodes.
  
  My problem is an issue raised by our internal system Auditors. Are asking that the commands rlogin and exec for AIX is disabled, because they feel that it is a security risk. Two orders prompt for a valid user name and password when they are used for the remote connection or execute a command.
  
  I looked at the RAC documentation search online and Metalink (I'm not an expert on Metalink, though!) as well as Google and could not find anything indicating that rlogin and exec are specifically required for CARS work properly.
  
  Can anyone offer advice or their point of view on whether or not these two commands should be enabled for RAC in order to function?
  
  I thank you in advance for any help, you can give it to me.

  Hi Mark,

  as far as my knowledge goes CARS use neither commands rlogin or exec.
  After the installation of the cluster Oracle simply communicates via. (Clusterware) TCP and UDP (RAC) and is only sending and receiving messages. It is not necessary at run time for a remote access connection.

  ALS if ssh and rsh are solemnly used for installation and connection (not for communication).
  Oracle recommends always to leave active because it makes life easier to activate ssh every time that a patch is necessary.

• Need to understand the basics of Oracle RAC and grid technology, for training

  I need to understand the infrastructure Oracle RAC and grid, a manager / training perspective.

  I see links here and here , so a few questions:

  -What is the fundamental difference from the layman's point of view (for example, a Manager)?

  -What training options are available for a generic 11g DBA to learn this new technology? I've seen this course from a partner of Oracle ("" courses: Oracle 11 g: RAC and Grid Infrastructure Administration accelerated Release 2 ""), to a boat load of money, during 5 days I think. So we are looking for something a bit more reasonable (and accessible), for example, books, online, etc.

  For a very basic definition, ACR is technology that is used by the database and IM is the infrastructure that makes the CAR work. In a response to the forum, this is probably all that can be said about the two. For a very long answer, you should read the links you cited.

  # 2, the course you are looking at is called accelerated because it combines two courses in one week training-RAC (4) and GI (3). So it's a day 7 curriculum that we would do in a 5 day course and who must justify its cost. But let me say, it's a really very good. But on the other side, it can be pretty intimidating to someone who does not already know these technologies. So I suggest that you send your team to each course individually and no doubt after doing some research. They can start to read the following books

  Pro Oracle Database 11g RAC on Linux

• 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?

• 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.

  Concerning

  Thank you mseberg

  This command is the full backup or a backup of level 0?

  full backup as compressed backupset
  data include current controlfile more archivelog deletion entry;

  We use command below for the full backup of database.
  database backup incremental level 0 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL0_%D_%M_%Y'
  include current controlfile
  tag 'datafile_full ';

  We use the command below to the increment backup
  database backup incremental level 1 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL1_%D_%M_%Y'
  include current controlfile
  tag 'datafile_Incr ';

  What is the different when we use
  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

  or

  full backup as backupset compressed database include controlfile current more archivelog delete all input;

• Difference between srvctl relocate scan and scan_listener?

  Hi all
  
  I have a 2-node RAC cluster using 11.2.0.2 grid Infrastructure.
  
  I'm trying to get well clear in my mind what the difference is between moving SCANNING using srvctl relocate scan and SCAN_LISTENER use srvctl move scan_listener
  
  Can anyone provide me explain when you would use each order and the effect there?
  
  Thank you very much.

  Hello

  See here for a closer explanation of the SCAN:

  http://www.Oracle.com/technetwork/database/clustering/overview/scan-129069.PDF

  Regarding your questions: the difference between a SCAN VIP and VIP normal CARS, is that a node has the VIP CARS he wants to run on and each has one node (so that you have only 3 SCANs). If it fails over to another node, the normal VIP exists, but does not accept connections, while the SCAN is not set on a node and can run on any node in the cluster (and will accept connections at any time).

  Now it works, VIP SCAN to the SCAN listener (otherwise it would not make sense). This is why there is really no difference in moving the SCAN VIP (because this will trigger a move of the listener), or to pass the SCAN_Listener (since this will move the VIP depends).

• Split of RAC and ASM

  Hi all
  
  
  I am running the DB RAC and ASM instance @ the same oracle home.
  I want an environment in which the ASM instance should run on its own oracle home. Pourrait procedures expert advice?

  1. install RBDMS s/w in a new location, such as an oracle of new home.
  2. once the installation is complete, stop the asm & RAC instances which uses this ASM instance
  3 copy the pfile asm file to the new location
  3 update the new location of oracle_home in the use of OCR to ASM

  srvctl change asm n -i [o ] [Pei ]

  * Set if pfile in the default location ($ORACLE_HOME/dbs), no need to specify.

  4 start the db ASM and RAC one by one.

• Completely remove installation RAC and ASM

  Hi all
  
  I tried to solve the problem on our server of CARS of single node of development for a few weeks now (with the participation of MOS). That it took so long to get anywhere, the decision was taken completely uninstall everything and start from scratch.
  
  As I build the server, I'm not aware of the RAC and ASM installation procedure. I need basically a blank slate - I can't manually delete the directories Oracle will help me this time due to ASM, ocr and voting disks and my colleague has mentioned something about the disks formatted in ocfs.

• RAC and standalone 10g EE databases on Solaris containers, ¿certified?

  Hello
  
  I said to check if it is possible on the same server running Solaris 10 coexists a RAC database and a stand-alone database, two g 10 EA.
  
  Containers would be used, therefore, with regard to the information to the I saw on Metalink, databases that are not CARS are certified to work on global and non-global containers and Oracle RAC is not certified nor supported in local containers.
  
  So, I think that the only option would be to install RAC on the global zone and the standalone database on a non-global zone.
  
  And my question is, if we should go for this configuration, it is certified and might have the support of Oracle?
  
  Thanks in advance.

  You're right, rac is not supported in solaris zones/containers. I think what you're suggesting (instance of rac and clusterware in global and sometimes unique area in containers) is supported, but please consider that your rac database could get expelled from the cluster for a reason or another which means a reboot of the server that would take also down all instances of monkey.

  If you are on SPARC CMT you can use LDOMs.
