The ovcoreid command is used to display existing OvCoreId values and, in addition, create and set new OvCoreId values on the local node.

NOTE: Changing the OvCoreId of a system is analogous to giving the system a new identity and is an action that should only be executed if the consequences are fully understood. Changing the OvCoreId of a system requires a number of significant changes including the need for a new certificate, and having to do appropriate reconfiguration of the OpenView server(s).

Parameters and options:

-show [-ovrg <OV_Resource_Group>]

Displays the current OvCoreId of the system (configuration setting CORE_ID in namespace [sec.core]). This is the default if no parameters are specified. If the OvCoreId you want to show belongs to an OpenView Resource Group, use the -ovrg option to specify the name of the Resource Group. If an OV Resource Group is specified, the corresponding configuration settings will be read or modified as well.

If you specify a non-existent OV Resource Group, ovcoreid displays the local OvCoreId.

-create [-force] [-ovrg <OV_Resource_Group>]

Generates a new OvCoreId. If a CORE_ID value already exists, the existing OvCoreId is only overridden when -force is specified. If the OvCoreId you want to show belongs to an OpenView Resource Group, use the -ovrg option to specify the name of the Resource Group. If an OV Resource Group is specified, the corresponding configuration settings will be read or modified as well.

If you specify a non-existent OV Resource Group, ovcoreid displays an error.

-set [-force] [-ovrg <OV_Resource_Group>]

Sets a specific OvCoreId. The -force option must be used if an OvCoreId value has already been set. If the OvCoreId you want to show belongs to an OpenView resource group, use the -ovrg option to specify the name of the resource group. If an OV Resource Group is specified, the corresponding configuration settings will be read or modified as well.


Returns the version of the tool (the component version).


Display all available command options.

The following exit values are returned:

Corresponding error messages are written to stderror.


The following examples show you how to use the ovcoreid command:

On list node CoreID on the server:

# opcnode -list_id
List of IDs for node(s):
Name = ID = bd995f0c-973b-754b-0718-afc25cde7f3f
Operation successfully completed.

To list node coreID on the node with agent installed

/opt/OV/bin/ovcoreid -show

To set ID on the server use

opcnode -chg_id id=8e475c38-8fb4-754b-0680-946436ccb281

To set ID on the node you can use command

ovcoreid -set bd995f0c-973b-754b-0718-afc25cde7f3f -force

Display the OvCoreId for the local node:

ovcoreid -show

To create and set a new OvCoreId on the local node:

ovcoreid -create

To set the specified OvCoreId on the local node:

ovcoreid -set <OvCoreId>

To create a certificate file on the server

opccsacm -issue -name -file /tmp/sp79d.cert -pass xyz1234

To copy it to the node:

scp /tmp/sp79d.cert [email protected]:/

To import certificate from a file on the node

export PATH=$PATH:/opt/OV/bin
/opt/OV/bin/ovcert -importcert -file sp79d.cert -pass xyz1234

   opcnode -list_id
   opcnode -chg_id id=8e475c38-8fb4-754b-0680-946436ccb281
to check
   opcnode -list_id

Create certificate

  opcragt -status

Restore certificate

ovcert -importcert -file /sp78d.cert -pass xyz1234

See also Undefined certificate state

To install the certificates manually

To install the certificates manually, follow these steps:

a. Set the installation type to MANUAL by entering the following command:


b. Check if ovcoreid is set by entering the following command:

$ ovcoreid -show

If ovcoreid is not set, the following message will be displayed:

INFO: No OvCoreId is set.

c. If ovcoreid is not set, create the ovcoreid by entering the following


$ ovcoreid -create

An error message "ERROR: No input stream" will be displayed that can be ignored.

d. To check whether the settings are correct, run ovconfget command

For example,







e. Log in to the Operations Manager Server on UNIX as a root user and

add the "coreid" of  Unix managed node manually to the Operations

Manager Server by entering the following command:

#/opt/OV/bin/OpC/utils/opcnode -chg_id node_name=node id=coreid_of_the_node

For example,

#/opt/OV/bin/OpC/utils/opcnode -chg_id node_name= id= fc200278-8f899-701f-0e73-cbd79be7b384

f. Create a signed certificate and the corresponding private key for a specific managed node manually using the opccsacm command line tool. You must provide a password to encrypt the created data.
