If you install Oracle Database Client on a computer with no other Oracle software installed, Oracle Universal Installer creates an Oracle base directory for you. If Oracle software is already installed, one or more Oracle base directories already exist. In the latter case, Oracle Universal Installer offers you a choice of Oracle base directories into which you can install Oracle Database Client.
You are not required to create an Oracle base directory before installation, but you can do so if you want. You can install all Oracle components in multiple Oracle homes on the same computer. However, some components can only support one active instance at a time. This means that the current latest installation renders the previous one inactive. These components are:. Oracle Database Client can be installed in the same Oracle Database home if both products are at the same release level.
For example, you can install Oracle Database Client 10 g Release 2 If you apply a patch set before installing the client, then you must apply the patch set again. Oracle Universal Installer will prompt you for an Oracle home directory, whether you have other Oracle software installed on the computer or not.
You cannot install products from one release of Oracle Database Client into an Oracle home directory of a different release. For example, you cannot install Oracle Database 11 g release 1 You can install this release more than once on the same system as long as each installation is installed in a separate Oracle home directory. Use the In-Place Upgrade feature to upgrade an existing client installation to the latest release by installing the new client software into an existing client home with the same installation type.
For example, if release This upgrade is only possible in a client home and not in any other Oracle home that contains non-client installations, such as Database installations. This upgrade does not delete files in the client home that are commonly updated by other users. For example, configuration data files. This upgrade cannot be performed if processes associated with the Oracle Database Client home are running. This functionality is available starting with Oracle Database 11 g Release 2 To install the software from the hard disk, you must either download it and unpack it, or copy it from the installation media, if you have it.
You must complete the following steps:. The remote DVD drive that you want to use must allow shared access. To set this up, perform these steps on the remote computer that has the DVD drive:.

If you want to install and run Oracle Database Client on a remote computer that is, the remote computer has the hard drive and will run Oracle Database Client components , but you do not have physical access to the computer, you still can perform the installation on the remote computer if it is running remote access software such as VNC or Symantec pcAnywhere. You also need the remote access software running on your local computer. If you have copied the contents of the Oracle Database Client DVD to a hard drive, you can install from the hard drive.
Make sure that the remote access software is installed and running on the remote and local computers. On the remote computer, map a drive letter to the shared hard drive. You would use the remote access software to do this on the remote computer. Through the remote access software, run Oracle Universal Installer on the remote computer.

To make sure the primary database is configured for switchover, we must create the standby redo logs on the primary server.
Start the auxillary instance on the standby server by starting it using the temporary "init. DO not attempt to use OS authentication. If you prefer, you can set a delay between the arrival of the archived redo log and it being applied on the standby server using the following commands.
Provided you have configured standby redo logs, you can start real-time apply using the following command. By default, for a newly created standby database, the primary database is in maximum performance mode.
The mode can be switched using the following commands. Note the alterations in the redo transport attributes. A database can be in one of two mutually exclusive modes primary or standby. These roles can be altered at runtime without loss of data or resetting of redo logs. This process is known as a Switchover and can be performed using the following statements.
Once this is complete, test the log transport as before. If everything is working fine, switch the primary database back to the original server by doing another switchover.
