cluvfy comp peer

Use the cluvfy comp peer component verification command to check the compatibility and properties of the specified nodes against a reference node. You can check compatibility for non-default user group names and for different releases of the Oracle software. This command compares physical attributes, such as memory and swap space, and user and group values, kernel settings, and installed operating system packages.

Syntax

cluvfy comp peer -n node_list [-refnode node]
  [-r {10.1 | 10.2 | 11.1 | 11.2 | 12.1}] [-orainv orainventory_group]
  [-osdba osdba_group] [-verbose]

Parameters

Table A-20 cluvfy comp peer Command Parameters

Parameter Description
-refnode

The node that CVU uses as a reference for checking compatibility with other nodes. If you do not specify this option, then CVU reports values for all the nodes in the node list.

-n node_list

The comma-delimited list of nondomain qualified node names on which to conduct the verification.

-r {10.1 | 10.2 | 11.1 |
 11.2 | 12.1}

Specifies the software release that CVU checks as required for installation of Oracle Clusterware or Oracle RAC. If you do not specify this option, then CVU assumes Oracle Clusterware 12c or Oracle Database 12c.

-orainv orainventory_group

The name of the Oracle Inventory group. If you do not specify this option, then CVU uses oinstall as the inventory group.

Note: This parameter is not available on Windows systems.

-osdba osdba_group

The name of the OSDBA group. If you do not specify this option, then CVU uses dba as the OSDBA group.

Note: This parameter is not available on Windows systems.

-verbose

CVU prints detailed output.

Usage Notes

Peer comparison with the -refnode option compares the system properties of other nodes against the reference node. If the value of the other node is not greater than the value for that of the reference node, then CVU flags that comparison as a deviation from the reference node. If a group or user exists on neither the reference node nor on the other node, then CVU reports a match to indicate that there is no deviation from the reference node. Similarly, CVU reports as mismatched a comparison with a node that has less total memory than the reference node.

Example

Comparing the configuration of select cluster nodes

The following command lists the values of several preselected properties on different nodes from Oracle Database 12c:

cluvfy comp peer -n node1,node2,node4,node7 -verbose
