You can use the CVU configuration file to define specific inputs for the execution of CVU. The path for the configuration file is Grid_home/cv/admin/cvu_config (or Staging_area\clusterware\stage\cvu\cv\admin on Windows platforms). You can modify this file using a text editor. The inputs to CVU are defined in the form of key entries. You must follow these rules when modifying the CVU configuration file:
Key entries have the syntax name=value
Each key entry and the value assigned to the key only defines one property
Lines beginning with the number sign (#) are comment lines and are ignored
Lines that do not follow the syntax name=value are ignored
The following is the list of keys supported by CVU:
CV_NODE_ALL: If set, it specifies the list of nodes that should be picked up when Oracle Clusterware is not installed. By default, this entry is commented out.
CV_ORACLE_RELEASE: If set, it specifies the specific Oracle release (10.1, 10.2, 11.1, 11.2, or 12.1) for which the verifications have to be performed. If set, you do not have to use the -r release option wherever it is applicable. The default value is 12.1.
CV_RAW_CHECK_ENABLED: If set to TRUE, it enables the check for accessibility of shared disks on Linux and UNIX systems. This shared disk accessibility check requires that you install the cvuqdisk RPM Package Manager (rpm) on all of the nodes. By default, this key is set to TRUE and shared disk check is enabled.
CV_ASSUME_DISTID: This property is used in cases where CVU cannot detect or support a particular platform or a distribution. Oracle does not recommend that you change this property as this might render CVU non-functional.
CV_XCHK_FOR_SSH_ENABLED: If set to TRUE, it enables the X-Windows check for verifying user equivalence with ssh. By default, this entry is commented out and X-Windows check is disabled.
ORACLE_SRVM_REMOTECOPY: If set, it specifies the location for the scp or rcp command to override the CVU default value. By default, this entry is commented out and CVU uses /usr/bin/scp and /usr/sbin/rcp.
ORACLE_SRVM_REMOTESHELL: If set, it specifies the location for ssh command to override the CVU default value. By default, this entry is commented out and the tool uses /usr/sbin/ssh.
CV_ASSUME_CL_VERSION: By default, the command line parser uses crs activeversion for the display of command line syntax usage and syntax validation. Use this property to pass a version other than crs activeversion for command line syntax display and validation. By default, this entry is commented out.
If CVU does not find a key entry defined in the configuration file, then CVU searches for the environment variable that matches the name of the key. If the environment variable is set, then CVU uses its value, otherwise CVU uses a default value for that entity.
