export NEWVER=112030
In situations where you intend to have multiple separate ORACLE_HOMEs at the same version on the same host then you may wish to append the ORACLE_SID as shown in the example below (where ORCL is the ORACLE_SID)...
export NEWVER=112030ORCL
Run as 'root'...
/u01/img/112030/database/rootpre.sh
cd /u01/img/112030/database
./runInstaller
The log will have a name starting with installActions and will be in /u01/app/oraInventory/logs
Run root.sh (as 'root') as shown in the output of RunInstaller.
If this install created the Oracle Inventory, you will be asked to run two scripts as shown below...
/u01/app/oraInventory/orainstRoot.sh
/u01/app/oracle/product/${NEWVER}/root.sh
