2. Operating System Requirements

Directory Server is supported on these operating systems: Red Hat Enterprise Linux 4 and 5 (x86 and x86_64), HP-UX 11i (IA 64), and Sun Solaris 9 (sparc 64-bit). The specific operating system requirements and kernel settings, patches, and libraries are listed for each.

•Section 2.1, “Using dsktune”

•Section 2.2, “Red Hat Enterprise Linux 4 and 5”

•Section 2.3, “HP-UX 11i”

•Section 2.4, “Sun Solaris 9”

Along with meeting the required operating system patches and platforms, system settings, like the number of file descriptors and TCP information, should be reconfigured to optimize the Directory Server performance.

Directory Server includes a tool, dsktune, which simplifies configuring your system settings. This section describes what settings to change on the machine on which Directory Server is installed.

2.1. Using dsktune

After the packages for Directory Server are installed there is tool called dsktune which can scan a system to check for required and installed patches, memory, system configuration, and other settings required by Directory Server. The dsktune utility even returns information required for tuning the host server's kernel parameters.

NOTE

The setup program also runs dsktune, reports the findings, and asks you if you want to continue with the setup procedure every time a Directory Server instance is configured.

Red Hat recommends running dsktune before beginning to set up the Directory Server
