Updates the health check policy for a given load balancer and backend set.


oci lb health-checker update [OPTIONS]

Required Parameters

--backend-set-name [text]

The name of the backend set associated with the health check policy to be retrieved.


--interval-in-millis [integer]

The interval between health checks, in milliseconds.


--load-balancer-id [text]

The OCID of the load balancer associated with the health check policy to be updated.

--port [integer]

The backend server port against which to run the health check.


--protocol [text]

The protocol the health check must use; either HTTP or TCP.


--response-body-regex [text]

A regular expression for parsing the response body from the backend server.


--retries [integer]

The number of retries to attempt before a backend server is considered “unhealthy”. This number also applies when recovering a server to the “healthy” state.


--return-code [integer]

The status code a healthy backend server should return.


--timeout-in-millis [integer]

The maximum time, in milliseconds, to wait for a reply to a health check. A health check is successful only if a reply returns within this timeout period.



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/Content/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 for the load balancer. This value can be obtained from a GET or POST response for any resource of that load balancer.

For example, the eTag returned by getListener can be specified as the ifMatch for updateRuleSets.

The resource is updated or deleted only if the ETag you provide matches the resource’s current ETag value.


--is-force-plain-text [boolean]

Specifies if health checks should always be done using plain text instead of depending on whether or not the associated backend set is using SSL.

If “true”, health checks will be done using plain text even if the associated backend set is configured to use SSL.

If “false”, health checks will be done using SSL encryption if the associated backend set is configured to use SSL. If the backend set is not so configured the health checks will be done using plain text.


--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.

--url-path [text]

The path against which to run the health check.


--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 SUCCEEDED --wait-for-state FAILED 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:

--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 lb load-balancer create --generate-param-json-input subnet-ids > subnet-ids.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.
