Spotlight on Oracle 10.10 - Release Notes

Configure the Unix System

To monitor a Unix system with Spotlight, ensure the Unix system is configured as follows.

Unix servers and versions.

Spotlight on Unix supports the following server operating systems:

  • Oracle Solaris 9, 10, 11
  • HP-UX 11i, 11i v2, 11i v3
  • IBM AIX 5.2, 5.3, 6.1, 7.1
  • Red Hat operating system based on Linux 2.4, 2.6 and 3.10 kernels
  • SUSE operating system based on Linux 2.4, 2.6 and 3.0 kernels
  • Oracle Enterprise Linux (OEL) based on Linux 2.4, 2.6 and 3.8 kernels

Unix programs.

Ensure the following Unix programs are accessible to the Unix login (through Spotlight):

  • Perl 5.x
  • awk
  • cat
  • date
  • df
  • grep
  • ifconfig
  • iostat (not HP-UX)
  • netstat
  • ps
  • sar
  • sed
  • tr
  • uname
  • uptime
  • vmstat
  • wc
  • who

For HP-UX, additionally

  • bdf
  • cstm
  • getconf
  • swapinfo
  • /usr/sbin/ioscan


For AIX, additionally

  • lsattr
  • lsdev
  • lsps
  • prtconf

For Solaris, additionally

  • /etc/swap
  • mpstat
  • nawk
  • prtconf

Unix User Permissions and Installation Settings

  • The Unix user should have no special processing on log-on. In particular there must be no input required from the user, and nor should any special login banners be displayed.
  • On AIX, the user must be a member of the "adm" group to be able to run the sar command.
  • On Linux, the sysstat package must be installed to enable the user to get detailed disk I/O information.
  • On Linux the /proc filesystem must be present.
  • For connection using SSH, the sshd daemon must be installed and running.

Remote Connectivity: SSH or REXEC

Spotlight on Unix will require you to select the connection type: SSH or REXEC. Information on SSH and REXEC is freely available on the Internet. We recommend SSH as password data is transmitted encrypted. REXEC does not encrypt password data.


  • Make sure the relevant SSH or REXEC daemon is running on the Unix machine and is configured to receive remote connections.
  • Commands to observe system activity (for example, netstat, vmstat, iostat, sar) must be accessible to REXEC / SSH sessions for Spotlight to observe Unix activity. Ensure these commands are located in the search path for REXEC / SSH sessions. If not, Spotlight will display an error.

Notes (Specific to SSH):

  • Spotlight supports both SSH1 and SSH2 protocols.
  • To allow Spotlight to make SSH connections to any Unix or Linux hosts that permit SSH connections, you may need to alter the PasswordAuthentication configuration item in the sshd_config file. Set the value of PasswordAuthentication to yes. Once you have modified the sshd_config file you must restart the sshd process to apply the new setting.
  • Public-key encryption is supported under SSH2 only. DSA and RSA are supported.

Note (Specific to REXEC): When Spotlight is monitoring a Unix operating system via REXEC with a valid user ID and password, remote commands may not work on the Unix host unless that user ID is added to the /etc/hosts.equiv file on the host.
