This section describes the Oracle Database 11g Release 1 (11.1) features for Oracle Clusterware administration and deployment.
Oracle Clusterware Documented Separately
Oracle Clusterware is now documented in its own book. This book, Oracle Clusterware Administration and Deployment Guide, describes how to administer and deploy Oracle Clusterware. This book also contains information about the Oracle Clusterware API and API commands.
See Also:Your platform-specific Oracle Clusterware installation guide for more information about installing Oracle Clusterware
Oracle cloning procedures for Oracle Clusterware
This book includes new step-by-step procedures for cloning Oracle Clusterware homes to quickly create Oracle Clusterware environments on other nodes.

Optimal Flexible Architecture (OFA) ensures reliable installations and improves software manageability
This feature improves manageability by making default Oracle Database installations more compliant with Optimal Flexible Architecture (OFA) specifications. As a part of this feature, the Oracle Universal Installer has been updated so that the default installation follows Oracle's Optimal Flexible Architecture. This ensures reliable installations and improves software manageability.
In addition, Oracle Clusterware can be installed only once on the system, so a counter to track the number of times that Oracle Clusterware is installed is not required as it is for Oracle database homes and Oracle Database installations with Oracle RAC.

ocrconfig command options
ocrconfig command now includes a new
-manualbackup option that enables you to force a manual backup at any time, rather than wait for the automatic backup that occurs at 4 (or more) hour intervals. The new
-manualbackup option provides a method for obtaining a binary backup on demand, such as after you make changes to the Oracle Cluster Registry (OCR).
In addition, the existing
-showbackup option includes new
manual flags that you can optionally specify to display only the automatic backup information or manual backup information, respectively.
Add voting disks dynamically, with no downtime
You can now add a voting disk while the cluster is active. Cluster Synchronization Services (CSS) start to use the voting disk without the need to restart the cluster.
Improved Oracle Clusterware performance monitoring and diagnostics in Oracle Enterprise Manager
Both Oracle Enterprise Manager Database Control and Oracle Enterprise Manager Grid Control are cluster aware and provide a central console to manage your cluster database. From any location where you can access a web browser, you can manage Oracle Clusterware, application servers, host computers, and Web applications, as well as related hardware and software.
You now have the ability to see any given metric across database instances or hosts in the cluster as a tile chart. This high-level view capability means that you can review issues that are affecting the entire cluster as well as those that are affecting individual instances. This is a major enhancement in terms of how metrics are monitored for Oracle Clusterware. With Oracle Database 11g, you can see the roll-up or summary-based views as well as tile based views if you want to monitor how a metric performs across different hosts over a period of time.
