1.5.2 Temporary Disk Space Requirements

The Oracle installation program uses a temporary directory into which it extracts the files necessary to install the software on the target system. During the installation process, your temporary directory must contain sufficient space to accommodate the compressed Java run-time environment JRE bundled with the installation program and an uncompressed copy of the JRE that is expanded into the temporary directory. The extracted files are deleted from the temporary directory after the installation process. As a general rule, installation programs require approximately 2.5 times the amount of temporary space that is ultimately required by the installed files. By default, the installation program uses the following temporary directories: ■ Windows platforms: directory referenced by the TMP system variable ■ UNIX platforms: system-dependent temporary directory To ensure that you have adequate temporary space, you may want to allocate an alternate directory for this purpose. To do so, follow the instructions provided in the following table. Color bit depth display and size For graphical user interface GUI mode installation, 8-bit color depth 256 colors is required. For console-mode and silent-mode installation, there is no color bit depth requirement. JDK The Oracle Enterprise Repository installation program requires a Java run-time environment JRE to run. To run the .jar installation programs, you must have the appropriate version of the JDK installed on your system, and include the bin directory of the JDK at the beginning of the PATH variable definition. It is important that you use a JDK because the installation process assigns values to JAVA_HOME and related variables to point to the JDK directory. JDBC The Oracle Enterprise Repository installation program requires the location of supported JDBC driver files to communicate with a supported database server. Ensure that the JDBC driver files are compatible with your application servers JDKJRE version, before proceeding with the Oracle Enterprise Repository installation. When using the IBM WebSphere application server, the bundled JDKJRE does not support JDBC drivers that are compiled using a newer JDK. For example, the Oracle 11g JDBC driver, ojdbc6.jar, does not function within a WebSphere 6.1.0.5 installation, however, the ojdbc5.jar driver would be appropriate. Note: If you do not have enough temporary space to run the installation program, you are prompted to specify an alternate directory or exit the installation program. Table 1–1 Cont.

1.6 Database Installation Procedures

The database administrator must create an empty database for Oracle Enterprise Repository to install its files into. A user for this database must also be created for example, OER_USER and that user must have database owner privileges on the Oracle Enterprise Repository database. This section contains the following topics: ■ Section 1.6.1, Oracle Database Installation ■ Section 1.6.2, Oracle Real Application Clusters Database Installation ■ Section 1.6.3, SQL Server 2008 Database Installation ■ Section 1.6.4, UDB Database Installation

1.6.1 Oracle Database Installation

Appropriate administrative privileges are necessary to complete this process. This section contains the following topics: ■ Section 1.6.1.1, Oracle Database ■ Section 1.6.1.2, Prerequisites ■ Section 1.6.1.3, Create the Tablespaces ■ Section 1.6.1.4, Build a Database User

1.6.1.1 Oracle Database

1. Connect to the database as a DBA. 2. From a SQL Plus command prompt, run: select from nls_database_parameters where Parameter=NLS_CHARACTERSET; The output has two columns, Parameter and Value. The most common Values are: ■ UTF-8 Encoding: AL32UTF8 International support ■ ISO-8859-1 Encoding: WE8ISO8859P1 U.S. English Encoding Platform To allocate more space in the temp folder Windows Do one of the following: ■ Set the TMP system variable to a directory of your choice. ■ If starting the installation program from the command line, include the -Djava.io.tmpdir=tmpdirpath option, replacing tmpdirpath with the full path of the directory that you want to designate as a temporary storage area for the Oracle Enterprise Repository installation program. For example: java -jar OER1111xx_generic.jar -Djava.io.tmpdir=D:\Temp UNIX Enter the following option on the command line when you start the installation program: java -jar OER1111xx_generic.jar -Djava.io.tmpdir=tmpdirpath Here, tmpdirpath is the full path of the directory that you want to designate as a temporary storage area for the Oracle Enterprise Repository installation program.
