This chapter provides information about the hardware and software items required for the installation of the Oracle9i Application Server, Oracle Portal-to-Go client, and the online documentation. The topics include:

• Hardware Requirements

• Software Requirements

• Certified Software

• Oracle Portal-to-Go Client Requirements

• Online Documentation Requirements

Hardware Requirements

The following table contains the hardware requirements for Oracle9i Application Server.

Hardware Items	Required
CPU	An Intel compatible 486 or higher processor
Memory	128 MB
Disk Space	Oracle HTTP Server Only: 550 MB Standard Edition: 1.63 GB Enterprise Edition: 2.56 GB
Total Pagefile Size	500 MB

Make note of the following:

• The disk space must be available on a single drive. Oracle9i Application Server does not support spanning the installation over multiple drives.

• For Standard Edition Only: You will need an additional 430 MB disk space to install the Oracle 8i JVM database. The database files do not have to be installed on the same disk as the Oracle9i Application Server ORACLE_HOME.

• For Enterprise Edition Only: Memory for Oracle Web Cache should be based on the following formula:

  (average HTTP object size) * (maximum number of objects you want to cache).

  Thus, if you want to cache 100,000 objects and the average size of the objects is 3 KB, then set the maximum cache size to at least 3 GB.

Software Requirements

The following table contains the software requirements for Oracle9i Application Server.

Software Items	Version
Operating System	Microsoft Windows NT with Service Pack 3 (minimum) or 5 (recommended); Service Pack 4 has TCP/IP and Winsock issues Microsoft Windows 2000
Virtual Memory	At least 360 MB of free virtual memory. To change the amount of virtual memory, go to Windows Control Panel and open System. Under the performance tab, change the amount of virtual memory.

Path Environment Variable

If the value of the user's PATH environment variable is over 1,024 bytes, then the following error may occur when the installer starts up the Oracle HTTP Server process:

This error can be resolved by doing either one of the following:

• Shortening the length of the PATH environment variable.

• Downloading a patch from Microsoft to correct the problem in cmd.exe. The path is described in Microsoft Knowledge Base article Q268722.
