HP-UX System Administrator's Guide: Overview HP-UX 11i v3 (B3921-90011, September 2010)
HP-UX provides the following commonly used shells for command entry:
• sh - the POSIX shell
• ksh - the Korn shell
• csh - the C shell
Though not officially shells, two related utilities work closely with shells to provide multiple
sessions on a single terminal:
shl
The Shell Layer Manager provides a means for interacting with more than one shell from
a single using shell layers. Each layer represents a virtual device. The current layer is the
one that can receive keyboard input. Other layers have input blocked. Output from multiple
layers is multiplexed onto a single terminal. See shl(1) for complete details.
tsm
The Terminal Session Manager, similar to the Shell Layer Manager, allows a user to interact
with multiple shells from a single terminal. Each shell is bound to a virtual device emulating
a physical terminal. tsm hot keys allow the user to switch between (and create new)
sessions. See tsm(1) for complete details.
The HP System Management Homepage Command Line Interface
If you need to enter a quick command line command from within the HP SMH graphical user
interface and do not want to start up a shell in a separate window, click on the Tasks menu item
near the top of the page and then select either Run Command or Run Command as Root from
the System section on the resulting panel.
Tools for Managing Multiple Servers
This section describes tools used for managing multiple instances of HP-UX.
HP Systems Insight Manager (HP SIM)
When you have multiple systems to manage, use the HP Systems Insight Manager (SIM). The HP
Systems Insight Manager is:
• Used for single point administration of multiple servers
• Capable of managing multiple servers of varying OS types:
— HP-UX 11i
— Linux
— Microsoft Windows
• Web based (accessible from any supported browser)
• Secure (uses SSL-secure authentication)
• Compatible with the OpenView Suite of products and with Serviceguard clusters.
Managing Multiple Servers from a Single Point of Control Using HP SIM
While the HP Systems Insight Manager can be used to manage a single HP-UX server, it is
probably better to use the “HP System Management Homepage (HP SMH)” for that purpose.
HP Systems Insight Manager allows you to manage multiple servers called managed systems from
a Central Management Server (CMS). Collectively, the CMS and the managed systems are referred
to as a management domain. The CMS is also a managed system within its own management
domain and can simultaneously be a managed system of management domains controlled from
other CMSs.
The CMS is the server where the HP Systems Insight Manager software resides, and you can
access this software from any network client (any computer capable of accessing the CMS via a
web browser (for a graphical user interface), or via ssh (for a secure textual user interface). The
network clients can be, but do not have to be members of the managed domain.
