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):

For HP-UX, additionally

For AIX, additionally

For Solaris, additionally

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.

Notes:

• 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.
