Oracle Application Server B32100-01 Installation Manual page 27

Table 2–2 (Cont.) System Requirements
Item Requirement
Processor type 64-bit HP-UX Itanium processor
To determine the processor type, run the following command:
prompt> /usr/bin/getconf KERNEL_BITS
Checked by Installer: No
Processor speed 400 MHz or faster
Checked by Installer: Yes
Memory The memory requirements provided for the various installation types represents enough
physical memory to install and run
production sites, you should configure at least 1 GB of physical memory. For sites with
substantial traffic, increasing the amount of memory further may improve your
performance. For Java applications, you should either increase the maximum heap allocated
to the OC4J processes, or configure additional OC4J processes to utilize this memory. See the
Oracle Application Server Performance Guide for details.
To determine the optimal amount of memory for your installation, the best practice is to
load test your site. Resource requirements can vary substantially for different applications
and different usage patterns. In addition, some operating system utilities for monitoring
memory can overstate memory usage (partially due to the representation of shared
memory). The preferred method for determining memory requirements is to monitor the
improvement in performance resulting from the addition of physical memory in your load
test. Refer to your platform vendor documentation for information on how to configure
memory and processor resources for testing purposes.
OracleAS Infrastructure:

To determine the amount of memory, enter the following command:
# /usr/sbin/dmesg | grep "Physical"
Checked by Installer: Yes
OracleAS Metadata Repository and Identity Management: 1 GB
Identity Management only: 1 GB
OracleAS Metadata Repository only: 1 GB
The installer checks the amount of memory on your computer and will warn you if
your computer does not meet the minimum memory requirements.
