However, you can also use Oracle Universal Installer to complete silent-mode installations using response files, without using the GUI.

If you need to perform multiple installations of Oracle Database Client, you may want to use silent or response file mode, with response files. In these modes, at each computer, you run Oracle Universal Installer from the command line using a response file.

The response file is a text file containing the settings you normally enter in the Oracle Universal Installer GUI dialog boxes. This method lets you quickly perform multiple installations using similar settings for each computer.

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:.

In Share name , give it a share name such as dvd. You will use this name when you map the DVD drive on the local computer in step d of the next section. Click Permissions. You need at least "read" permission for the user who will be accessing it to install Oracle Database. Perform these steps on the local computer to map a remote DVD drive and to run Oracle Universal Installer from the mapped drive:.

In Folder , enter the location of the remote DVD drive using the following format:. For example. If you need to connect to the remote computer as a different user, click different user name , and enter the username. 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. You access Oracle Universal Installer from the shared hard drive. On the remote computer, map a drive letter to the shared DVD drive. Make sure that you completely review and understand the terms of the license.

Most downloads include the Development License. This section contains the following topics:. On the download page, identify the required disk space by adding the file sizes for each required file. In most cases, the available disk space must be at least twice the size of all the archive files. On the file system that you selected in step 4 , create a parent directory for each product, for example OraDBClient11g , to hold the installation directories.

Download all of the installation archive files to the directories that you created in step 5. Reads a RAW string value from a file and adjusts the file pointer ahead by the number of bytes read.

This procedure closes all open file handles for the session. This procedure copies a contiguous portion of a file to a newly created file. The source file is opened in read mode. The destination file is opened in write mode. A starting and ending line number can optionally be specified to select a portion from the center of the source file for copying. The line number at which to stop copying.

The default is NULL, signifying end of file. Normally, data being written to a file is buffered. The data must be terminated with a newline character. Flushing is useful when the file must be read while still open.

For example, debugging messages can be flushed to the file so that they can be read immediately. It raises an exception if the file is not open. It returns 0 for the beginning of the file.

This function opens a file. You can specify the maximum line size and have a maximum of 50 files open simultaneously. Directory location of file. This string is a directory object name and is case sensitive. The default is uppercase. File name, including extension file type , without directory path.

Maximum number of characters for each line, including the newline character, for this file minimum value 1, maximum value FOPEN returns a file handle, which must be passed to all subsequent procedures that operate on that file. This function opens a file in Unicode for input or output, with the maximum line size specified. You can have a maximum of 50 files open simultaneously. With this function, you can read or write a text file in Unicode instead of in the database charset.

Maximum number of characters for each line, including the newline character, for this file. An exception is returned on failure. This procedure renames an existing file to a new name, similar to the UNIX mv function. Permission on both the source and destination directories must be granted. You can use the overwrite parameter to specify whether or not to overwrite a file if one exists in the destination directory.

This procedure adjusts the file pointer forward or backward within the file by the number of bytes specified. You must know the number of bytes by which you want to navigate. If the beginning of the file is reached before the number of bytes specified, then the file pointer is placed at the beginning of the file. This procedure reads text from the open file identified by the file handle and places the text in the output buffer parameter. Text is read up to, but not including, the line terminator, or up to the end of the file, or up to the end of the len parameter.

File handle is invalid. File could not be opened or operated on as requested. Destination buffer too small, or operating system error occurred during the read operation. Operating system error occurred during the write operation.

The requested operation failed because the file is open. The filename parameter is invalid. Permission to access to the file location is denied. The requested file delete operation failed. The requested file rename operation failed. Users with DBA privilege. All users. A numeric value indicating the internal file handle number.

Indicates whether the file was open as a binary file, or as a text file. Closes a file. Closes all open file handles.
