== delete-resource-ref

Removes a reference to a resource

[[sthref967]]

=== Synopsis

[source]
----
asadmin [asadmin-options] delete-resource-ref [--help]
[--target target] reference_name
----

[[sthref968]]

=== Description

The `delete-resource-ref` subcommand removes from a cluster or an
unclustered server instance a reference to a resource (for example, a
JDBC resource). This effectively results in the removal of the resource
from the JNDI tree of the targeted instance or cluster.

The target instance or instances making up the cluster need not be
running or available for this subcommand to succeed. If one or more
instances are not available, they will no longer load the resource in
the JNDI tree the next time they start.

Removal of the reference does not result in removal of the resource from
the domain. The resource is removed only by the `delete` subcommand for
that resource (for example, `delete-jdbc-resource`).

This subcommand is supported in remote mode only.
