UNIX

The UNIX system to which you are installing the Policy Server must meet the following minimum system requirements:

CPU
- Solaris–UltraSparc 440MHz or better.
- Red Hat–x86 or x64.
  Note:The Red Hat 6 operating system relies on entropy for performance. Increase entropy before installing the component. Without sufficient entropy, the installation can take an exceedingly long time to complete. We recommend that you use the following command to set a symbolic link:
```
mv /dev/random /dev/random.org
ln -s /dev/urandom /dev/random
```
Memory—2 GB of system RAM.
Note: We recommend 2 GB of RAM for Policy Server processing. We recommend at least 4 GB of RAM be available to the Policy Server host system for additional processing.
Available disk space:
- 4 GB of free disk space.
- 1 GB of free disk space in /tmp.
  Note: Typically, 10 MB of free disk space in /tmp is required for the daily operation of the Policy Server. The Policy Server creates files and named pipes under /tmp. The path to which these files and pipes are created cannot be changed.
JRE—The required JRE version is installed on the system to which you are installing the Policy Server.
LDAP directory server or relational database—Be sure that the LDAP directory server or relational database you plan on using as a policy store is supported.

Note: For a list of supported CA and third-party components, refer to the SiteMinder r12.5 Platform Support Matrix on the Technical Support site.
