This chapter contains information that supplements the Red Hat Directory 8.0 Server Installation
Guide for installing the product on HP-UX.
3.1 Preparing for Red Hat Directory Server 8.0 Installation
This section describes how to prepare for installing Red Hat Directory Server 8.0.
3.1.1 Hardware Requirements
Red Hat Directory Server 8.0 has the following are hardware requirements:
• HP 9000 (PA2.0) or HP Integrity system
• At least 256 MB of memory. HP recommends that you have 512 MB to 4 GB of memory for
best performance on large production systems.
The physical memory requirements for each Directory Server process depend on your
particular configuration and database. Each server process requires at least 15 MB of memory.
However, the server caches recently used entries. Depending on the size of the database
served and the size of the entries cached, the memory requirements for a typical Directory
Server process can exceed 2 GB.
For more information, see Section 4.3.2 (page 29).
• CD-ROM drive to load the software or an Internet connection to Software Depot to download
the software.
3.1.2 Disk Space Requirements
The disk space requirements for the /opt/dirsrv, /etc/opt/dirsrv/ and /var/opt/
dirsrv directories are as follows:
• /opt/dirsrv
The initial product installation requires 115 MB of space in /opt/dirsrv for executables,
libraries, scripts, and other related data. Each Directory Server instance created requires
1 MB of space in /opt/dirsrv.
• /etc/opt/dirsrv
The initial product installation requires 0.5 MB of space in /etc/opt/dirsrv for shared
configuration files. Each Directory Server instance created requires 1 MB of space in /etc/
opt/dirsrv. The space usage in /etc/opt/dirsrv increases if customized schema are
added for the Directory Server instance and as certain PKI-related objects are added such
as trusted issuers in the certificate database.
• /var/opt/dirsrv
Each Directory Server instance created requires a minimum of 33 MB of space in /var/
opt/dirsrv for logs and database files. The space usage in /var/opt/dirsrv increases
as LDAP entries are added to the Directory Server, as log files grow, and if the backend
database cache size is increased.
The file system used for database files must have large file system support enabled. For
more information, see Section 3.1.6.3 (page 21).
To determine the available disk space on your system, use the following commands:
bdf /opt/dirsrv
bdf /etc/opt/dirsrv
bdf /var/opt/dirsrv
For more information, see bdf(1m).
