Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
To configure Grid Infrastructure for a Stand-Alone Server run the following command as the root user:
/app/app/grid/product/11.2.0/perl/bin/perl -I/app/app/grid/product/11.2.0/perl/lib -I/app/app/grid/product/11.2.0/crs/install /app/app/grid/product/11.2.0/crs/install/roothas.pl
To configure Grid Infrastructure for a Cluster perform the following steps:
1. Provide values for Grid Infrastructure configuration parameters in the file - /app/app/grid/product/11.2.0/crs/install/crsconfig_params. For details on how to do this, see the installation guide.
2. Run the following command as the root user:
/app/app/grid/product/11.2.0/perl/bin/perl -I/app/app/grid/product/11.2.0/perl/lib -I/app/app/grid/product/11.2.0/crs/install /app/app/grid/product/11.2.0/crs/install/rootcrs.pl
To update inventory properties for Grid Infrastructure, perform the following
steps. If a pre-11.2 home is already configured, execute the following:
11.2_Home/oui/bin/runInstaller -updateNodeList -silent -local CRS=false ORACLE_HOME=pre-11.2_Home
Always execute the following to register the current home:
11.2_Home/oui/bin/runInstaller -updateNodeList -silent -local CRS=true ORACLE_HOME=11.2_Home.
If either home is shared, provide the additional argument -cfs.
