CPU, Disk, and TMP Requirements for Oracle9iAS

Table B-1 lists the CPU, Disk, and TMP requirements for Oracle9iAS.

Table B-1 Oracle9i Application Server CPU, Disk, and TMP Requirements

Hardware Type	Minimum Requirement
CPUFoot 1	See the Oracle9i Application Server Installation Guide
Disk SpaceFoot 2	Oracle9i Application Server J2EE and Web Cache: 435 MB Portal and Wireless: 1.20 GB Business Intelligence and Forms: 1.91 GB Unified Messaging: 2.02 GB Oracle9iAS Infrastructure: 1.91 GB Oracle9iAS Developer Kits: 701 MB
TMP or Swap Space	1 GB
/var/tmp Space	Oracle9i Application Server J2EE and Web Cache: 5 MB Portal and Wireless: 12 MB Business Intelligence and Forms: 95 MB Unified Messaging: 95 MB Oracle9iAS Infrastructure: 7 MB Oracle9iAS Developer Kits: 5 MB
Monitor	256 color viewing capability

1 Oracle recommends a multiple CPU computer. 2 The disk space must be available on a single disk. Oracle9i Application Server does not support spanning the installation over multiple disks.

Memory Requirements for Oracle9iAS

Table B-2 lists the memory requirements for Oracle9iAS.

Table B-2 Oracle9i Application Server Memory Requirements

Install Type	Component Configuration	Minimum Memory Requirements
J2EE and Web Cache	Oracle HTTP Server Oracle9iAS Containers for J2EE Oracle9iAS Web CacheFoot 1	128 MB
All other Oracle9iAS install types	Configure up to three additional Oracle9iAS components	256 MB
All other Oracle9iAS install types	Configure four or more additional Oracle9iAS components	512 MB
Oracle9iAS Infrastructure	Oracle9iAS Metadata Repository Oracle9iAS Single Sign-On Oracle Internet Directory Oracle Management Server J2EE and Web Cache (Infrastructure Instance)	512 MB
Oracle9iAS Developer Kits	Oracle XML Developer Kit Oracle9iAS Portal Developer's Kit Oracle9iAS Wireless Developer's Kit Oracle LDAP Developer's Kit J2EE and Web Cache	128 MB

1 Memory for Oracle9iAS 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 1,000,000 objects and the average size of the objects is 3 KB, then set the maximum cache size to at least 3 GB.
