Oracle Optimal Flexible Architecture (OFA)

Standard is recommendations for naming files, mount points, directory structures, filenames, scripting techniques and folders when installing 10g and implementing an oracle database.. Anyone who knows the OFA can navigate an Oracle environment to quickly find the software and files used for the database and the instance. This standardization increases productivity and avoids errors.

Benefits by using Optimal Flexible Architecture

• Organizes large amounts of complicated software and data on disk to avoid device bottlenecks and poor performance
• Facilitates routine administrative tasks, such as software and data backup functions, which are often vulnerable to data corruption
• Alleviates switching among multiple Oracle databases
• Adequately manages and administers database growth
• Helps to eliminate fragmentation of free space in the data dictionary, isolates other fragmentation, and minimizes resource contention

Specifications

A Pentium III or Pentium 4 based PC with at least 800 MHz processor, 256 MB of ram (512 is such better) and at least 10 Gigabytes of free disk space.

If you only have 256 MB of RAM, make sure you have Windows manage at least 400 MB swap file (virtual memory). .

At least 6 GB of free disk space:

Space to download or copy source ZIP files: 1.5 GB
Space to unpack source ZIP files: 1.5 GB
Space to install Oracle10g Software: 2.0 GB
Space for Oracle data files (varies): 2.0 to 5.0 GB

Installation

After downloading the Oracle10g from Oracle TechNet, then you need to unzip the files and double click on the setup.exe program to get the installation process started.

It is assumed that this is a fresh install so no other Oracle products should be installed at this time.

In this screen, the Source and Destination locations must be selected.

The Source path should reflect either your CD-ROM or the directory in which you unzipped the source files. Leave this as the default. In the example above, the source files were unzipped into c:\DOCUME~1HARI\LOCALS~1\temp\rar$ex12.1593\disk\stage\product.xml.

For the Destination, leave the Oracle Home named oraDb10g_home1 as the default. Choose a hard disk drive that has at least 6 gigabytes of free space. In the example here, we are using the E: drive.

Leave the \Oracle\product\10.1.0\db_1 path as it is (the default). If you must change this to a different drive, only change the drive letter and not the directories.

Click on the Next button to select installation type. This may take up to 2 minutes (depending on the speed of your machine). Once the product information has been read, the following 3 "Available Products" options are presented:

Keep the default names for GLOBAL and the SID Otherwise, use the following (make a note of these for later on): Global Database Name is orcl, Oracle SID is orcl

Click on the Next button to continue to the "database file storage option" screen

In this step, you need to select where the Oracle data files will be located. In large operations, we typically keep the data files on a separate disk (or disks), however, for this install, keep the default storage

Click on the Next button to move to the "Summary" screen:

In this screen (shown above), the products and files that will be installed are summarized. Note that in this example, it will take 1.5 GB MB of disk space for the installation of the software. Additional space will be required for the default database.

If everything looks OK at this point, click on the Install button to begin the installation.

During the install, you will notice various Oracle products being copied over to the hard disk.

Once the installation is completed, the next step will be to configure the various additional services and the database.
