Memory to install or upgrade 

512 MB is the recommended size. 256 MB is the minimum size. 

Some optional installation features are enabled only when sufficient memory is present. For example, if you install from a DVD with insufficient memory, you install through the Solaris installation program's text installer, not through the GUI. For more information about these memory requirements, see Table 1–3.

Swap area 

512 MB is the default size. 

You might need to customize the swap space. Swap space is based on the size of the system's hard disk.

Processor requirements 

200–MHz or faster processor is required.

File systems 

For each file system that you create, allocate an additional 30 percent more disk space than you need to enable you to upgrade to future Solaris versions.  

By default, the Solaris installation methods create only root (/) and /swap. When space is allocated for OS services, the /export directory is also created. If you are upgrading to a major Solaris release, you might need to reslice your system or allocate double the space that you need at installation time. If you are upgrading to an update, you could prevent having to reslice your system by allocating extra disk space for future upgrades. A Solaris update release needs approximately 10 percent more disk space than the previous release. You can allocate an additional 30 percent of disk space for each file system to allow space for several Solaris updates.

The /var file system

If you intend to use the crash dump feature savecore(1M), allocate double the amount of your physical memory in the /var file system.

Swap 

The Solaris installation program allocates a default swap area of 512 Mbytes under the following conditions:

• If you use the installation program's automatic layout of disk slices

• If you avoid manually changing the size of the swap slice

By default, the Solaris installation programs allocate swap space by placing swap so that it starts at the first available disk cylinder (typically cylinder 0 on SPARC based systems). This placement provides maximum space for the root (/) file system during the default disk layout and enables the growth of the root (/) file system during an upgrade.

If you think you might need to expand the swap area in the future, you can place the swap slice so that it starts at another disk cylinder by using one of the following methods.

• For the Solaris installation program, you can customize the disk layout in cylinder mode and manually assign the swap slice to the desired location.

• For the custom JumpStart installation program, you can assign the swap slice in the profile file. For more information about the JumpStart profile file, see Creating a Profile in Solaris 10 5/08 Installation Guide: Custom JumpStart and Advanced Installations.

For an overview of the swap space, see Chapter 20, Configuring Additional Swap Space (Tasks), in System Administration Guide: Devices and File Systems.

A server that is providing home directory file systems 

By default, home directories are usually located in the /export file system.

The Solaris software group you are installing 

A software group is a grouping of software packages. When you are planning disk space, remember that you can add or remove individual software packages from the software group that you select. For information about software groups, see Disk Space Recommendations for Software Groups.

Upgrade  

• If you are using Solaris Live Upgrade to upgrade an inactive boot environment and want information about disk space planning, see Solaris Live Upgrade Disk Space Requirements in Solaris 10 5/08 Installation Guide: Solaris Live Upgrade and Upgrade Planning

• If you are using other Solaris installation methods to plan disk space, see Upgrading With Disk Space Reallocation in Solaris 10 5/08 Installation Guide: Planning for Installation and Upgrade.

Language support 

For example, Chinese, Japanese, or Korean. If you plan to install a single language, allocate approximately 0.7 Gbytes of additional disk space for the language. If you plan to install all language supports, you need to allocate up to approximately 2.5 Gbytes of additional disk space for the language supports, depending on the software group you install. 

Printing or mail support 

Allocate additional space. 

Additional software or third-party software 

Allocate additional space. 

Entire Solaris Software Group Plus OEM Support

This software group also enables the system to recognize network interfaces, but does not activate network services. 

2.0 Gbytes 

Network connection 

Is the system connected to a network? 

Networked/Nonnetworked 

Network security 

Starting with the Solaris 10 11/06 release, you have the option during an initial installation to change the network security settings so that all network services, except Secure Shell, are disabled or restricted to respond to local requests only. This security option is only available during an initial installation, not during an upgrade. An upgrade maintains any previously set services. If necessary, you can restrict network services after an upgrade by using the netservices command.

During the installation, you can select restricted network security. Or, you can enable a larger set of services as in previous Solaris releases. You can safely select the restricted network security option, as any services can be individually enabled after installation. For further information about these options, see Planning Network Security in Solaris 10 5/08 Installation Guide: Planning for Installation and Upgrade.

The network services can be enabled after installation by using the netservices open command or by enabling individual services by using SMF commands. See Revising Security Settings After Installation in Solaris 10 5/08 Installation Guide: Planning for Installation and Upgrade.

Restricted/Open network security

Domain Name 

Provide the name of the domain in which the system resides. 

During installation, you can choose the default NFSv4 domain name. Or, you can specify a custom NFSv4 domain name. 

For instructions about how to find the domain name on a running system, see Checking for the NFS Version 4 Domain in System Administration Guide: Network Services.

For more information about specifying a domain name, see NFSv4 Domain Name Configurable During Installation in Solaris 10 5/08 Installation Guide: Planning for Installation and Upgrade. To preconfigure the NFSv4 domain name in the sysidcfg file, see nfs4_domain Keyword in Solaris 10 5/08 Installation Guide: Network-Based Installations.

NIS+ and NIS 

Do you want to specify a name server or let the installation program find one? 

If you want to specify a name server, provide the following information. 

Specify One/Find One* 

Server's host name: 

• For NIS clients, type the following command to display the server's host name.

  # ypwhich

• For NIS+ clients, type the following command to display the server's host name.

  # nisping

Server's IP Address: 

• For NIS clients, type the following command to display the server's IP address.

  # ypmatch nameserver-name hosts

• For NIS+ clients, type the following command to display the server's IP address.

  # nismatch nameserver-name hosts.org_dir

Server's IP Address: 

To display the server's IP address, type the following command. 

# getent hosts dns

You can enter a list of domains to search when a DNS query is made. 

List of domains to be searched: 

The domain name system (DNS) is the naming service that the Internet provides for TCP/IP networks. DNS provides host names to the IP address service. DNS simplifies communication by using machine names instead of numerical IP addresses. DNS also serves as a database for mail administration. 

LDAP 

Provide the following information about your LDAP profile. 

Profile Name: 

Profile Server: 

If you specify a proxy credential level in your LDAP profile, gather this information. 

Proxy-bind distinguished name: 

Proxy-bind password: 

Lightweight Directory Access Protocol (LDAP) defines a relatively simple protocol for updating and searching directories that are running over TCP/IP. 

Default Route 

Do you want to specify a default route IP address or let the Solaris installation program find one?

The default route provides a bridge that forwards traffic between two physical networks. An IP address is a unique number that identifies each host on a network. 

You have the following choices:

• You can specify the IP address. An /etc/defaultrouter file is created with the specified IP address. When the system is rebooted, the specified IP address becomes the default route.

• You can let the Solaris installation program detect an IP address. However, the system must be on a subnet that has a router that advertises itself by using the ICMP router discovery protocol. If you are using the command-line interface, the software detects an IP address when the system is booted.

• You can choose None if you do not have a router or do not want the software to detect an IP address at this time. The software automatically tries to detect an IP address on reboot.
