This section describes Oracle Database 11g release 1 (11.1) features as they pertain to the installation and configuration of Oracle Clusterware and Oracle Real Application Clusters (Oracle RAC) The topics in this section are:
With Oracle Database 11g release 1, Oracle Clusterware can be installed or configured as an independent product, and additional documentation is provided on storage administration. For installation planning, note the following documentation:
This book provides an overview and examples of the procedures to install and configure a two-node Oracle Clusterware and Oracle RAC environment.
This book (the guide that you are reading) provides procedures either to install Oracle Clusterware as a standalone product, or to install Oracle Clusterware with either Oracle Database, or Oracle RAC. It contains system configuration instructions that require system administrator privileges.
This platform-specific book provides procedures to install Oracle RAC after you have completed successfully an Oracle Clusterware installation. It contains database configuration instructions for database administrators.
This book provides information for database and storage administrators who administer and manage storage, or who configure and administer Automatic Storage Management (ASM).
This is the administrator's reference for Oracle Clusterware. It contains information about administrative tasks, including those that involve changes to operating system configurations and cloning Oracle Clusterware.
This is the administrator's reference for Oracle RAC. It contains information about administrative tasks. These tasks include database cloning, node addition and deletion, Oracle Cluster Registry (OCR) administration, use of SRVCTL and other database administration utilities, and tuning changes to operating system configurations.
The following is a list of enhancements and new features for Oracle Database 11g release 1 (11.1):
To install Oracle HTTP Server, use the "Oracle Fusion Middleware Web Tier Utilities 11g (188.8.131.52.0)" media or download.
This feature introduces a new
SYSASM privilege that is specifically intended for performing ASM administration tasks. Using the
SYSASM privilege instead of the
SYSDBA privilege provides a clearer division of responsibility between ASM administration and database administration.
OSASM is a new operating system group that is used exclusively for ASM. Members of the OSASM group can connect as
SYSASM using operating system authentication and have full access to ASM.
With Oracle Clusterware 11g, the Oracle Clusterware Process Monitor Daemon (
oprocd) monitors the system state of cluster nodes. You should use both OPROCD and the hangcheck timer to provide input/output (IO) fencing for the cluster, and to ensure no stray writes occur from an evicted node in an Oracle RAC cluster.
Note:This guidance for the fencing processes has changed. Previous versions of this release guide indicated that
oprocdreplaced the hangcheck-timer. This was incorrect. Both processes are required.
The Oracle Validated Configuration RPM can be installed on servers using Red Hat Enterprise Linux or Oracle Linux operating systems. It is available from the Unbreakable Linux Network (ULN). This RPM completes most preinstallation configuration tasks required for installing Oracle Clusterware, including setting kernel parameters and adding required kernel RPMs. It also prepares a server for installation of Oracle RAC.
