Oracle Database 11g Release 2 (184.108.40.206) RAC On Oracle Linux 6.3 Using VirtualBox
Jan 01, · When using Oracle Database 11g Release 2 client libraries, row prefetching also benefits fetching from REF CURSORS. This section shows the oci_bind_array_by_name() function that allows a PHP array to be retrieved from, or passed to, a PL/SQL procedure. May 26, · Database Configuration Assistant (DBCA) is a Java based GUI tool which is very useful to create, configure and drop databases. From 10g R2, this has been enhanced to manage the Automatic Storage Management (ASM) instance.
Home » Articles » 11g » Here. This article describes the installation of Oracle Database 11g release 2 One of the biggest obstacles preventing people from setting up test RAC environments is the requirement for shared storage. In a production environment, shared storage is often provided by a SAN or high-end NAS device, but both of these options are very expensive when all you want to do is get some experience installing and using RAC. A cheaper alternative is to use a FireWire disk enclosure to allow two machines to access the same disk sbut that still costs money and requires two servers.
A third option is to use virtualization to fake the shared storage. In addition, it allows you to set how to download a video with realplayer cloud shared virtual disks, overcoming the obstacle of expensive shared storage. First, install the VirtualBox software. On RHEL and its clones you do this with the following type of command as the root user.
The package name will vary depending on the host distribution you are using. Now we must define the two virtual RAC nodes. We can save time by defining one VM, then cloning it when it is installed. Start VirtualBox and click the "New" button on the toolbar. Accept the default location and set the size to "30G", then click the "Create" button.
If you can spread the virtual disks onto different physical disks, that will improve performance. The "olrac1" VM will appear on the left hand pane. Scroll down the "Details" tab on the right and click on the "Network" link. Move "Hard Disk" to the top of the boot order and uncheck the "Floppy" option, then click the "OK" button. With the new VM highlighted, click the "Start" button on the toolbar. Continue through the Oracle Linux 6 installation as you would for a basic server.
A general pictorial guide to the installation can be found here. To be consistent with the rest of the article, how far is galveston from san antonio texas following information should be set during the installation:. You are free to change the IP addresses to suit your network, but remember to stay consistent with those adjustments throughout the rest of the article.
Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. The Additional Setup is required for all installations.
If you have not used the "oracle-rdbms-servergR2-preinstall" package to perform all prerequisites, you will need to manually perform the following setup tasks.
How to make sausage and tomato pie addition to the basic OS installation, the following packages must be installed whilst logged in as the root user. This includes the bit and bit how to make fresh horseradish of some packages. The commented out packages are those already installed if you have followed the suggested package selection.
Perform the following steps whilst logged into the "olrac1" virtual machine as the root user. The DNS configuration is described here. If you have the Linux firewall enabled, you will need to disable or configure it, as shown here or here.
The following is an example of disabling the firewall. If you want to deconfigure NTP do the following. We've made a lot of changes, so it's worth doing a reboot of the VM at this point to make sure all the changes have taken effect.
If you get the option to what type of wax is best for a brazilian wax take it. If not, then run the following commands. The VM will need to be restarted for the additions to be used properly. The next section requires a shutdown so no additional restart is needed at this time. On the host server, create 4 sharable virtual disks and associate them as virtual media using the following commands.
You can pick a different location, but make sure they are outside the existing VM directory. Start the "olrac1" virtual machine by clicking the "Start" button on the toolbar. When the server has started, log in as the root user so you can configure the shared disks. The current disks can be seen by issuing the following commands. Use the "fdisk" command to partition the disks sdb to sde.
The following output shows the expected fdisk output how to know if a person is rich the sdb disk. Once all the disks are partitioned, the results can be seen by repeating the previous "ls" command. Configure your UDEV rules, as shown here.
Create the file if it doesn't already exist. All parameters for a single entry must be on the same line. The disks should now be visible and have the correct ownership using the following command. If they are not visible, your UDEV configuration is incorrect and must be fixed before you proceed.
Later versions of VirtualBox allow you to clone VMs, but these also attempt to clone the shared disks, which is not what we want. Instead we must manually clone the VM. Create the "olrac2" virtual machine in VirtualBox in the same way as you did for "olrac1", with the exception of using an existing "olrac2. Remember to add the second network adaptor as you did on the "olrac1" VM. When the VM is created, attach the shared disks to this VM.
Start the "olrac2" virtual machine by clicking the "Start" button on the toolbar. Ignore any network errors during the startup. Log in to the "olrac2" virtual machine as the "root" user so we can reconfigure the network settings to match the following. Check the MAC address of each of the available network connections.
Don't worry that they are listed as "eth2" and "eth3". These are dynamically created connections because the MAC address of the "eth0" and "eth1" connections is incorrect. If it is incorrect, amend it to match the settings described above. Restart the "olrac2" virtual machine and start the "olrac1" virtual machine. When both nodes have started, check they can both ping all the public and private IP addresses using the following commands. Check the UDEV rules are working on both machines.
For some reason, this doesn't seem to happen on my OL6. Prior to 11gR2 we would probably use the "runcluvfy.
If you are intending to configure SSH connectivity using the installer this check should be omitted as it will always fail. If you want to setup SSH connectivity manuallythen once it is done you can run the "runcluvfy.
Before moving forward you should probably shut down your VMs and take snapshots of them. If any failures happen beyond this point it is probably better to switch back to those snapshots, clean up the shared drives and start the grid installation again. An alternative to cleaning up the shared disks is to back them up now using zip and just replace them in the event of a failure. Make sure both virtual machines are started, then login to "olrac1" as the oracle user and start the Oracle installer.
Click the "SSH Connectivity Click the "Setup" button to to configure SSH connectivity, and the "Test" button to test it once it is complete. Click the "Identify network interfaces Once you are happy with them, click the "OK" button and the "Next" button on the previous screen. Enter the ASM password, select "dba" as the group and click the "Next" button. Return the main screen and select all 4 disks and click the "Next" button.
Wait while the prerequisite checks complete. If you have any issues, either fix them or check the "Ignore All" checkbox and click the "Next" button. The output of the root. Example output can be seen here Node1Node2. Once the scripts have completed, return to the "Execute Configuration Scripts" screen on "rac1" and click the "OK" button.
Provided this is the only error, it is safe to ignore this and continue by clicking the "Next" button. Make sure the what is 1 2 acre and "olrac2" virtual machines are started, then login to "olrac1" as the oracle user and start the Oracle installer. Uncheck the security updates checkbox and click the "Next" button and "Yes" on the subsequent warning dialog.
The storage type should be set to "Automatic Storage Manager". Enter the appropriate passwords and database name, in this case "RAC. Wait for the prerequisite check to complete.
If there are any problems either fix them, or check the "Ignore All" checkbox and click the "Next" button. When prompted, run the configuration scripts on each node.
