Other Requirements You must install as root in order to use well-known port numbers (such
as 389) that are less than 1024. If you do not plan to use port numbers
less than 1024, you do not need to install as root. If you plan to run as
root, you should also install as root and specify nobody as the default
run-as user and group.

OS Version Solaris 9 with relevant patches. For details, see
Section 2.3.4 Sun Solaris 9 Operating SystemSun Solaris 9 Operating
System. Solaris can run in 32-bit or 64-bit operating system mode.
CPU UltraSparc-IIi 300Mhz or faster (64-bit).
Memory/RAM 256 MB. However, you should plan for 1 GB of RAM for best
performance on large production systems.
Storage Space/Hard Disk Approximately 300 MB of disk space for a minimal installation. For
production systems, you should plan at least 2 GB to support the
product binaries, databases, and log files (log files require 1 GB by
default); 4 GB and greater may be required for very large directories.
To support database files that are larger than 2 GB, the machine must
be configured to support large files; you can do this by choosing
largefile.
Other Requirements You must install as root in order to use well-known port numbers (such
as 389) that are less than 1024. If you do not plan to use port numbers
less than 1024, you do not need to install as root. If you plan to run as
root, you should also install as root and specify nobody as the default
run-as user and group.
Table 2-4. Sun Solaris Platform Requirements
2.2. Hardware Requirements
On all platforms, you need:
• Roughly 200 MB of disk space for a minimal installation. For production systems, you should plan
at least 2 GB to support the product binaries, databases, and log files (log files require 1 GB by
default); 4 GB and greater may be required for very large directories.
• 256 MB of RAM. However, you should plan for 1 GB of RAM for best performance on large
production systems.
The table below contains some guidelines for disk space and memory requirements depending on
the number of entries managed by your Directory Server. This assumes entries in the LDIF file are
approximately 100 bytes in size and only the recommended indexes are configured. If you are using
larger entries, make sure that at least four times the size of the LDIF file is available on disk.
Number of Entries Disk Space and Memory Required
10,000 - 250,000 entries Free disk space: 2 GB Free memory: 256 MB
