Description
===========

Updates a VCN by evaluating a sequence of patch instructions (JSON
List Patch). This operation is restricted to IPv6 CIDR-related fields
only. Supported selections (exact match) are:   - ipv6CidrBlock   -
ipv6PublicCidrBlock   - ipv6PrivateCidrBlocks   - byoipv6CidrDetails
Only the REPLACE operation is supported. The request must include the
If-Match header for optimistic concurrency control. This is an
asynchronous operation. The VCN’s lifecycleState is set to UPDATING
while the patch work request is in progress, and changes back to
AVAILABLE after the patch operation is complete. All patch
instructions are applied atomically as a single operation; either all
succeed or none are applied. NOTE: *ipv6PublicCidrBlock* represents
Oracle provided GUA on VCN. With PATCH API, customer can only remove
it if present. Since this is Oracle provided CIDR, there is no concept
of replacing with customer provided CIDR.


Usage
=====

   oci network vcn patch [OPTIONS]


Required Parameters
===================

--patch-vcn-instructions [complex type]

List of patch instructions for VCN. This is a complex type whose value
must be valid JSON. The value can be provided as a string on the
command line or passed in as a file using the file://path/to/file
syntax.

The "--generate-param-json-input" option can be used to generate an
example of the JSON which must be provided. We recommend storing this
example in a file, modifying it as needed and then passing it back in
via the file:// syntax.

--vcn-id [text]

Specify the OCID of the VCN.


Optional Parameters
===================

--from-json [text]

Provide input to this command as a JSON document from a file using the
file://path-to/file syntax.

The "--generate-full-command-json-input" option can be used to
generate a sample json file to be used with this command option. The
key names are pre-populated and match the command option names
(converted to camelCase format, e.g. compartment-id –> compartmentId),
while the values of the keys need to be populated by the user before
using the sample file as an input to this command. For any command
option that accepts multiple values, the value of the key can be a
JSON array.

Options can still be provided on the command line. If an option exists
in both the JSON document and the command line then the command line
specified value will be used.

For examples on usage of this option, please see our “using CLI with
advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Conte
nt/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--if-match [text]

For optimistic concurrency control. In the PUT or DELETE call for a
resource, set the *if-match* parameter to the value of the etag from a
previous GET or POST response for that resource. The resource will be
updated or deleted only if the etag you provide matches the resource’s
current etag value.

--max-wait-seconds [integer]

The maximum time to wait for the work request to reach the state
defined by "--wait-for-state". Defaults to 1200 seconds.

--wait-for-state [text]

This operation asynchronously creates, modifies or deletes a resource
and uses a work request to track the progress of the operation.
Specify this option to perform the action and then wait until the work
request reaches a certain state. Multiple states can be specified,
returning on the first state. For example, "--wait-for-state" ACCEPTED
"--wait-for-state" SUCCEEDED would return on whichever lifecycle state
is reached first. If timeout is reached, a return code of 2 is
returned. For any other error, a return code of 1 is returned.

Accepted values are:

   ACCEPTED, FAILED, IN_PROGRESS, SUCCEEDED

--wait-interval-seconds [integer]

Check every "--wait-interval-seconds" to see whether the work request
has reached the state defined by "--wait-for-state". Defaults to 30
seconds.

Example using required parameter
================================

Copy and paste the following example into a JSON file, replacing the
example parameters with your own.

       oci network vcn patch --generate-param-json-input patch-vcn-instructions > patch-vcn-instructions.json

Copy the following CLI commands into a file named example.sh. Run the
command by typing “bash example.sh” and replacing the example
parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-
like shell. You need to set up the OCI configuration and appropriate
security policies before trying the examples.
