[oracle@rhel63single database]$ ./runInstaller  -help

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2015-02-15_07-23-12AM. Please wait ...[oracle@rhel63single database]$ Usage:
runInstaller  [-options] [(<CommandLineVariable=Value>)*]

Where options include:
  -clusterware oracle.crs,<crs version>  
        Version of Cluster ready services installed.

  -crsLocation <Path>  
        Used only for cluster installs, specifies the path to the crs home location. Specifying this overrides CRS information obtained from central inventory.

  -invPtrLoc <full path of oraInst.loc>  
        Unix only. To point to a different inventory location. The orainst.loc file contains:
inventory_loc=<location of central inventory>
inst_group=<>

  -jreLoc <location>  
        Path where Java Runtime Environment is installed. OUI cannot be run without it.

  -logLevel <level>  
        To filter log messages that have a lesser priority level than <level>. Valid options are: severe, warning, info, config, fine, finer, finest, basic, general, detailed, trace. The use of basic, general, detailed, trace is deprecated.

  -paramFile <location of file>  
        Specify location of oraparam.ini file to be used by OUI.

  -responseFile <Path>  
        Specifies the response file and path to use.

  -attachHome  
        For attaching homes to the OUI inventory.

  -cfs  
        Indicates that the Oracle home specified is on cluster file system (shared). This is mandatory when '-local' is specified so that Oracle Universal Installer can register the home appropriately into the inventory.

  -clone  
        For making an Oracle Home copy match its current environment.

  -debug  
        For getting the debug information from OUI.

  -detachHome  
        For detaching homes from the OUI inventory without deleting inventory directory inside Oracle home.

  -enableRollingUpgrade  
        Used in cluster environment, to enable upgrade of a product on a subset of nodes (on which the product was installed).

  -executeSysPrereqs  
        Execute system pre-requisite checks and exit.

  -force  
        Allowing silent mode installation into a non-empty directory.

  -help  
        Displays above usage.

  -ignoreSysPrereqs  
        For ignoring the results of the system pre-requisite checks.

  -local  
        Performs the operation on the local node irrespective of the cluster nodes specified.

  -printdiskusage  
        Log debug information for disk usage.

  -printmemory  
        Log debug information for memory usage.

  -printtime  
        Log debug information for time usage.

  -relink  
        For performing relink actions on the oracle home
         Usage: -relink -maketargetsxml <location of maketargetsxml> [-makedepsxml <location of makedepsxml>] [name=value]

  -silent  
        For silent mode operations, the inputs can be a response file or a list of command line variable value pairs.

  -waitforcompletion  
        Installer will wait for completion instead of spawning the java engine and exiting.

  -suppressPreCopyScript  
        Suppress the execution of precopy script.

  -acceptUntrustedCertificates  
        Accept untrusted certificates from a secure site.

  -suppressPostCopyScript  
        Suppress the execution of postcopy script.

  -noconfig  
        Do not execute config tools.

  -noconsole  
        For suppressing display of messages to console. Console is not allocated.

  -formCluster  
        To install the Oracle clusterware in order to form the cluster.

  -remotecp <Path>  
        Unix specific option. Used only for cluster installs, specifies the path to the remote copy program on the local cluster node.

  -remoteshell <Path>  
        Unix specific option. Used only for cluster installs, specifies the path to the remote shell program on the local cluster node.

  -executePrereqs
        To execute only the prerequisite checks.

  -ignorePrereq
        To ignore running the prerequisite checks.

  -ignoreInternalDriverError
        To ignore any internal driver errors.

  -downloadUpdates
        To download updates only.

  -showProgress
        To show the installation progress on the console. This option is supported only in case of silent installation.

Command Line Variables Usage
  Command line variables are specified using <name=value>; for example:
    [ session: | compName: | compName:version: ]variableName=" valueOfVariable"]

   Session/Installer variables are specified using:
          [session:]varName=value
    Ex 1: session:ORACLE_HOME_NAME="OraHome"
    Ex 2: ORACLE_HOME_NAME="OraHome"
    The lookup order is session:varName then just varName. The session prefix is used to avoid ambiguity.

   Component variables are specified using:
          [compInternalName:[Version:]]varName
    Ex 1: oracle.comp1:1.0.1:varName="VarValue"
    Ex 2: oracle.comp1:varName="VarValue"
    The lookup order is compInternalName:Version:varName, then compInternalName:varName, then just varName.
