Update a backend set.

Request

Supported Media Types
Path Parameters
Header Parameters
  • 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.
  • Unique Oracle-assigned identifier for the request. Provide this request OCID if you need to contact Oracle about this request.
  • Minimum Length: 1
    Maximum Length: 64
    A token that uniquely identifies a request so it can be retried in case of a timeout or server error without risk of executing that same action again. Retry tokens expire after 24 hours, but can be invalidated before then due to conflicting operations (for example, if a resource has been deleted and purged from the system, then a retry of the original creation request may be rejected).
Body ()
The details to update a backend set.
Root Schema : UpdateBackendSetDetails
Type: object
The configuration details for updating a load balancer backend set. Avoid entering confidential information when you supply string values using the API.
Show Source
  • backends
    Unique Items Required: true
    An array of backends associated with the backend set.
  • HealthCheckerDetails
    The health check policy configuration.
  • Default Value: IPV4
    Allowed Values: [ "IPV4", "IPV6" ]
    The IP version associated with the backend set.
  • If this parameter is enabled, the NLB fleet in a particular AD will prefer backends within the same AD while load-balancing traffic.
  • If enabled, the network load balancer will continue to distribute traffic in the configured distribution in the event all backends are unhealthy. The value is false by default.
  • If enabled existing connections will be forwarded to an alternative healthy backend as soon as current backend becomes unhealthy.
  • Default Value: true
    If this parameter is enabled, then the network load balancer preserves the source IP of the packet when it is forwarded to backends. Backends see the original source IP. If the isPreserveSourceDestination parameter is enabled for the network load balancer resource, then this parameter cannot be disabled. The value is true by default.
  • Minimum Value: 1
    Maximum Value: 100
    When backends are added without weights, this value will represent the percent of backends that must be healthy within an AD for AD Affinity to be honored. When backends are added with weights, this value will represent the percent of weights that must be healthy within an AD for AD Affinity to be honored. If the percent of healthy backends falls below this threshold, traffic will be distributed across all healthy backends in all ADs. If this percent value is not specified then default will be 80.
  • Default Value: FIVE_TUPLE
    The network load balancer policy for the backend set. To get a list of available policies, use the [ListNetworkLoadBalancersPolicies](#/en/networkloadbalancer/20200501/networkLoadBalancerPolicy/ListNetworkLoadBalancersPolicies) operation. Example: FIVE_TUPLE
Nested Schema : backends
Type: array
Unique Items Required: true
An array of backends associated with the backend set.
Show Source
Nested Schema : HealthCheckerDetails
Type: object
The health check policy configuration.
Show Source
  • DnsHealthCheckerDetails
    DNS healthcheck configurations.
  • Default Value: 10000
    The interval between health checks, in milliseconds. The default value is 10000 (10 seconds). Example: 10000
  • The backend server port against which to run the health check. If the port is not specified, then the network load balancer uses the port information from the Backend object. The port must be specified if the backend port is 0. Example: 8080
    Example: 8080
  • Allowed Values: [ "HTTP", "HTTPS", "TCP", "UDP", "DNS" ]
    The protocol the health check must use; either HTTP or HTTPS, or UDP or TCP. Example: HTTP
  • Base64 encoded pattern to be sent as UDP or TCP health check probe.
  • A regular expression for parsing the response body from the backend server. Example: ^((?!false).|\s)*$
  • Base64 encoded pattern to be validated as UDP or TCP health check probe response.
  • Default Value: 3
    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. The default value is 3. Example: 3
  • The status code a healthy backend server should return. If you configure the health check policy to use the HTTP protocol, then you can use common HTTP status codes such as "200". Example: 200
    Example: 200
  • Default Value: 3000
    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. The default value is 3000 (3 seconds). Example: 3000
  • The path against which to run the health check. Example: /healthcheck
Nested Schema : BackendDetails
Type: object
The network network load balancing configuration details of a backend server.
Show Source
  • The IP address of the backend server. Example: 10.0.0.3
  • Default Value: IPV4
    Allowed Values: [ "IPV4", "IPV6" ]
    IP version associated with the BackendDetails object.
  • Default Value: false
    Whether the network load balancer should treat this server as a backup unit. If true, then the network load balancer forwards no ingress traffic to this backend server unless all other backend servers not marked as "isBackup" fail the health check policy. Example: false
  • Default Value: false
    Whether the network load balancer should drain this server. Servers marked "isDrain" receive no incoming traffic. Example: false
  • Default Value: false
    Whether the network load balancer should treat this server as offline. Offline servers receive no incoming traffic. Example: false
  • A read-only field showing the IP address/OCID and port that uniquely identify this backend server in the backend set. Example: 10.0.0.3:8080, or ocid1.privateip..unique_ID:443 or 10.0.0.3:0
  • Minimum Value: 0
    Maximum Value: 65535
    The communication port for the backend server. Example: 8080
  • The IP OCID/Instance OCID associated with the backend server. Example: ocid1.privateip..unique_ID
  • Minimum Value: 1
    Maximum Value: 100
    Default Value: 1
    The network load balancing policy weight assigned to the server. Backend servers with a higher weight receive a larger proportion of incoming traffic. For example, a server weighted '3' receives three times the number of new connections as a server weighted '1'. Example: 3
Nested Schema : DnsHealthCheckerDetails
Type: object
DNS healthcheck configurations.
Show Source
  • Minimum Length: 1
    Maximum Length: 255
    The absolute fully-qualified domain name to perform periodic DNS queries. If not provided, an extra dot will be added at the end of a domain name during the query.
  • Allowed Values: [ "IN", "CH" ]
    The class the dns health check query to use; either IN or CH. Example: `IN`
  • Allowed Values: [ "A", "TXT", "AAAA" ]
    The type the dns health check query to use; A, AAAA, TXT. Example: `A`
  • rcodes
    Minimum Number of Items: 1
    Unique Items Required: true
    An array that represents accepetable RCODE values for DNS query response. Example: ["NOERROR", "NXDOMAIN"]
  • Allowed Values: [ "UDP", "TCP" ]
    DNS transport protocol; either UDP or TCP. Example: `UDP`
Nested Schema : rcodes
