Oracle Solaris Cluster Overview |
1. Introduction to Oracle Solaris Cluster
Making Applications Highly Available With Oracle Solaris Cluster
Failover and Scalable Services and Parallel Applications
Oracle Solaris I/O Multipathing (MPxIO)
Hardware Redundant Array of Independent Disks Support
2. Key Concepts for Oracle Solaris Cluster
You can install, configure, and administer the Oracle Solaris Cluster system either though the Oracle Solaris Cluster Manager GUI or through the command-line interface (CLI).
The Oracle Solaris Cluster system also has a module that runs as part of Sun Management Center software that provides a GUI to certain cluster tasks.
Oracle Solaris Cluster Manager is a browser-based tool for administering Oracle Solaris Cluster systems. The Oracle Solaris Cluster Manager software enables administrators to perform system management and monitoring, software installation, and system configuration.
The Oracle Solaris Cluster Manager software includes the following features:
Built-in security and authorization mechanisms
Secure Sockets Layer (SSL) support
Role-based access control (RBAC)
Pluggable Authentication Module (PAM)
NAFO and IP network multipathing group administration facilities
Quorum devices, transports, shared storage device, and resource group administration
Sophisticated error checking and autodetection of private interconnects
The Oracle Solaris Cluster command-line interface (CLI) is a set of utilities you can use to install and administer Oracle Solaris Cluster systems, and administer the volume manager portion of Oracle Solaris Cluster software.
You can perform the following Oracle Solaris Cluster administration tasks through the Oracle Solaris Cluster CLI:
Validating an Oracle Solaris Cluster configuration
Installing and configuring Oracle Solaris Cluster software
Updating an Oracle Solaris Cluster configuration
Managing the registration of resource types, the creation of resource groups, and the activation of resources within a resource group
Changing node mastery and states for resource groups and device groups
Controlling access with role-based access control (RBAC)
Shutting down the entire cluster
The Oracle Solaris Cluster system also has a module that runs as part of Sun Management Center software. Sun Management Center software serves as the cluster's base for administrative and monitoring operations and enables system administrators to perform the following tasks through a GUI or CLI:
Configuring a remote system
Monitoring performance
Detecting and isolating hardware and software faults
Sun Management Center software can also be used as the interface to manage dynamic reconfiguration within Oracle Solaris Cluster servers. Dynamic reconfiguration includes domain creation, dynamic board attach, and dynamic detach.
In conventional UNIX systems, the root user, also referred to as superuser, is omnipotent, with the ability to read and write to any file, run all programs, and send kill signals to any process. Oracle Solaris role-based access control (RBAC) is an alternative to the all-or-nothing superuser model. RBAC uses the security principle of least privilege, which is that no user should be given more privilege than necessary for performing his or her job.
RBAC enables an organization to separate superuser capabilities and package them into special user accounts or roles for assignment to specific individuals. This separation and packaging enables a variety of security policies. Accounts can be set up for special-purpose administrators in such areas as security, networking, firewall, backups, and system operation.
