Ability to determine the amount of disk space required to install the Server on your system.
Try This: Determine the version of the operating system on your target system (either Solaris or NT) and make sure you've got enough disk space to complete the installation.
Factoid: Although the Server will run on systems with 32 MB of RAM, 64 MB is recommended.
See Chapter 1 of the Installation Guide.
> | # Requirements ### Disk Space Disk space requirements per platform is as follows:
> | Sun Solaris | HP-UX | AIX | Digital Unix | NT 4.0
> Archive File | 42 | 44 | 37 | 43 | 39
> Server Installation Image | 67 | 67 | 70 | 79 | 43
> Netscape Console Installation Image | 31 | 37 | 31 | 23 | 26
> Total | 140 | 148 | 138 | 145 | 108
### Platform Requirements The directory server is supported on most major Unix platforms and on Windows NT with the noted requirements: Solaris 2.5.1 or 2.6. Both with Sun's recommended patch set. HP-UX 11. with the following restrictions: Make sure the maxdsize kernel parameter is at least (cachesize*average size of your entries) + 4kb. That is, if your directory server cachesize is 1000 (this is the default), your average directory entry size is 20kb, then make sure your maxdsize kernel parameter is at least (1000 * 20000) + 4000, or at least 21MB. Make sure the maxfiles_lim kernel parameter is at least 2048 or the directory server will not be able to install. HP and Netscape recommend that you upgrade to patch PHNE_16645 if you already have patch PHNE_16283 installed. IBM AIX 4.2. The minimum patch level required to run on AIX 4.2 is AIX 4.2.1 with PTF U451634. Digital Unix 4.0B Windows NT 4.0 with service pack 3. The server must be installed on an NTFS operating system. On all platforms, 32 MB of RAM is required to run Directory Server 4.0. ### Browser Requirements You must use Netscape Communicator 4.04 or higher to administer the server. Reserve at least 10 MB of disk space for the browser.
