After unconfiguring the cluster, you will now have to configure the cluster as root user with the following example:
#$GI_HOME/crs/config/config.sh
The
config.sh
invokes Grid Infrastructure configuration framework in Graphical User Interface (GUI) mode, and
you need to provide the appropriate input through pages that displayed. Finally, you will have to run the root.sh to
complete the configuration.
After recovering the OCR file from various failure scenarios, run through the following set of postrecovery steps to
verify the OCR file integrity and cluster availability on all nodes:
# ocrcheck
# cluvfy comp ocr-n all -verbose
# crsctl check cluster -all
Summary
In a nutshell, this chapter summarized and offered the most useful tools, tips, and techniques to design and deploy
optimal database backup and recovery procedures in a RAC environment using the RMAN tool. In addition, the
internal mechanics behind instance and crash recovery operations in a RAC environment were explained in great
detail. The chapter concluded by discussing and demonstrating various OCR recovery scenarios.
