Oracle 11g RAC and Clusterware several houses of the databases

• 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.
  
  Kind regards

  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.

  I am using oracle 11g express edition, how I can change the service name and the port number?

  I am using oracle 11g express edition, how I can change the service name and the port number?

  What do you mean by "port number"? HTTP port (usually 8080), or listening port (normally 1521)?

  To change the name of the service, you can use (as a DBA or SYSDBA)

  SQL > alter system set service_name = '';

• I missed the SHIFT key and press several keys in the lower corner of my keyboard LH. Firefox split up into several iterations, and I had to reboot.

  I missed the SHIFT key and press several buttons in the lower left corner of my keyboard. Firefox has lost the tab that I was using and divided into a separate iteration for each other (plus two I had closed). I could not recover and had to close all but one of them and restore all my tabs.

  What I had done and how I should have recovered?

  First, you need to update to Firefox 18.0.1 Firefox updated to the latest version. The version you are on is bug and little course.

  Second, it looks like you may have entered groups of tabs. Use tab groups to organize a large number of tabs is that look familiar?

• Is it possible to install several facilities of the database on Windows?

  Hello world

  I have a Windows Server 2008 with Oracle 11 g R2 (11.2.0.3, Standard, 64 - bit) database. I need to install an additional database (11.2.0.3, Standard, 64 - bit) for tests on the same server. These tests are patches of database, which will first be applied to the new database before applying these fixes on the existing database, in order to assess potential problems after having patched.

  I'm used to install, configure and manage databases Oracle as a stand alone, RAC or physical standby via the DataGuard since 9i - as long as I'm in a UN * x / linux environment (Red Hat Enterprise Linux, CEntOs, Oracle Enterprise Linux, etc.). Implementation of multiple instances in a single or multiple homes has never been a problem for me so far.

  I already searched google, oracle.com and other related proceedings. But I have found no results on the installation of two or more homes to Oracle under Windows. I found the guidelines on copying / cloning an instance in a new home, but if I remember correctly, it is intended for copying / cloning on other servers and not on the same server. Given that the existing database is installed on Windows, I'm afraid I can damage the existing installation to rerun the configuration wizard, change the registry values for Windows, and the database running as a service.

  Is it possible to have several houses of the same Oracle database, with even the version, edition, and the archiecture (11.2.0.3, Standard, 64 - bit)?

  If so, how can I get it?

  Best regards

  You can run the Setup utility again and specify a different Oracle home. In fact, the installer can provide a different name automatically for you. It's been a while since I've done it, so I'm a little fuzzy on the details. How the two facilities are managed by different registry settings, such as ORACLE_HOME0 and ORACLE_HOME1.

  Another caveat is that when the management of these cases, make sure you start the utilities for each database to its respective home. So, in the menu start, you choose tell SQL * menu Dbhome1 more to manage a single instance and SQL * in the menu of dbhome2 to manage the other instance. It's so environment variables get ready properly before the application starts.

• Deployment of Oracle 11g RAC Release 2 with IBM midsize V7000

  At and deployment 11g rac with IBM midsize V7000 san with aix 6.1
  Is this possible using Oracle CRS without going to the OS like GPFS cluster

  Oracle Grid these days use ASM starts for vote and register files storage. So no need for a cooked cluster file system that must be mounted by all nodes. No need either directly with a gross storage logical unit number.

  ASM uses the LUN of the matrix of storage/SAN directly (as devices of rough blocks).

  Generally however, there are several I/O paths to that LUN on the SAN - in which case there is more than 1 device level o/s for this LUN. Multipath driver s/w addresses this and creates a logical (and redundant) device that sits at the top of several devices of i/o path to the level of the o/s.

  You configure ASM to use devices of paths multiples (as devices of rough blocks) - and applying exterrnal, normal or high redundancy necessary when creating starts on these logical multipath devices.

  The grid s/w and RAC database instances can then use ASM starts as cluster storage.

  This makes storage much easier layer management - and also provide a number of useful features too.

  This is also the approach recommended by Oracle Corp. for RAC - use ASM under the layer of management of storage between storage LUNS in the table and one side and CARS on the other.

• Stupid question: what is the difference between RAC and Clusterware?

  Hi all
  
  I'm about to start experimenting with the 11 G RAC Setup (to begin with, is that a cluster of a node, will try to add another later).
  
  I am reading the docs... I'm on that of clusterware installation, and it seems to indicate that the clusterware and RAC are two different things?
  
  http://download.Oracle.com/docs/CD/B28359_01/install.111/b28263/prelinux.htm#BABJHGBE
  
  With quotes like "UDP is the default for Oracle RAC interconnect protocol and TCP is the Protocol of interconnection for Oracle Clusterware. You must use a switch for interconnection. Oracle recommends using a dedicated switch. "
  
  Can someone tell me the difference? I know it sounds stupid, but it's confusing me, and I'm new on this.

  What is the difference between the Oracle Clusterware and Oracle Real Application Clusters?

  In case of failure of the system, put in cluster guarantees availability high for users. Redundant hardware components, such as the additional nodes, interconnection, and discs, allow the cluster to provide high availability. These redundant hardware architecture avoid the single points of failure and provide exceptional resilience fault.

  In environments Oracle Real Application Clusters (RAC), Oracle Clusterware monitors and manages Real Application Cluster databases. When a node of the cluster is started, all instances, auditors and the services are started automatically. If an instance fails, the clusterware automatically restarts the instance, so that the service is often restored prior to the notice of the administrator, he was down. In this sense Oracle Clusterware is the base of Oracle Real Application Clusters.

  In these environments CCR ensures the continuous operation of the database, but also scalability by running several bases of instance data at the same time, usually one on each node in the cluster.

• Oracle 11g RAC cure 7.5 on aix

  Hi Oracle experts
  
  Fact someboday on this forum has been working on an implementation of remedy 7.5 on Oracle RAC 11g /AIX?
  
  Best practices on this installation? BMC documentations are not detailed on the part of the Oracle at all.
  
  Please share...

  Hi Haggy

  We also do the same kind of project and I agree with you that the documentation regarding the installation of BMC is too thin to be called documentation. try to take a look at http://communities.bmc.com/communities/index.jspa and post your question on the forum that it would be better.

  You also have the opportunity to ask questions directly to the BMC support then you have found the official statements from the provider.

  I hope this helps.

  I wanted to tell temp is never off allocated. So, if a 'bad' query explodes temp. the only thing you can do is to create a new and drop the old one.

  11 GB temp is clearly ridiculous. Usually, this is caused by the merge join Cartesian paths in your instructions.

• Oracle 11g Client and Enterprise Manager

  Just need confirmation that the old Java based Enterprise Manager 10g left for always with 11g and there is no installation of 11g client management console (at least I can't find one). And after searching for the ndo son Oracle documentation, it seems that I can install database 11g on my local pc and then have a dbconsole (not the grid control). Please confirm that this dbconsole only points to the specific database that is installed on the same pc, and it cannot be used to manage remotely located 10 or 11 g databases. I'm still in the planning stages for the installation of grid control and want to use the more small enterprise manager - java control. But even once, there no such Oracle 11 g application now? I have to use the grid control to manage multiple databases?

  Confirmed. Identical to the installation of the database.

  And after searching for the ndo son Oracle documentation, it seems that I can install database 11g on my local pc and then have a dbconsole (not the grid control). Please confirm that this dbconsole only points to the specific database that is installed on the same pc, and it cannot be used to manage remotely located 10 or 11 g databases.

  Confirmed. The DB Console is linked to an ORACLE_HOME one HOST for a single INSTANCE. The HOST and the INSTANCE are used in the directory naming (of all stupidity) and the content of the configuration file under the ORACLE_HOME.

  I'm still in the planning stages for the installation of grid control and want to use the more small enterprise manager - java control. But even once, there no such Oracle 11 g application now? I have to use the grid control to manage multiple databases?

  Confirmed. Fortunately, the grid control is included in the license database in accordance with the manual of licenses of database, and you can place the grid on a separate machine control. As the Grid control is powered with a single agent for all products (and any other database) on the target host, the grid control puts on a much smaller footprint on a machine of database that even the old console Java.

  Note that the grid control of 11g (at least) will tomorrow announce Webcast - check the RTO.
