// UpdateSteeringPolicyDetails The body for updating a steering policy. New rules and answers provided in the request will
// replace the existing rules and answers in the policy.
// *Warning:* Oracle recommends that you avoid using any confidential information when you supply string values using the API.
type UpdateSteeringPolicyDetails struct {

	// A user-friendly name for the steering policy.
	// Does not have to be unique, and it's changeable.
	// Avoid entering confidential information.
	DisplayName *string `mandatory:"false" json:"displayName"`

	// The Time To Live for responses from the steering policy, in seconds.
	// If not specified during creation, a value of 30 seconds will be used.
	Ttl *int `mandatory:"false" json:"ttl"`

	// The OCID of the health check monitor providing health data about the answers of the
	// steering policy.
	// A steering policy answer with `rdata` matching a monitored endpoint will use the health
	// data of that endpoint.
	// A steering policy answer with `rdata` not matching any monitored endpoint will be assumed
	// healthy.
	HealthCheckMonitorId *string `mandatory:"false" json:"healthCheckMonitorId"`

	// The common pattern (or lack thereof) to which the steering policy adheres. This
	// value restricts the possible configurations of rules, but thereby supports
	// specifically tailored interfaces. Values other than "CUSTOM" require the rules to
	// begin with an unconditional FILTER that keeps answers contingent upon
	// `answer.isDisabled != true`, followed
	// _if and only if the policy references a health check monitor_ by an unconditional
	// HEALTH rule, and require the last rule to be an unconditional LIMIT.
	// What must precede the LIMIT rule is determined by the template value:
	// - FAILOVER requires exactly an unconditional PRIORITY rule that ranks answers by pool.
	//   Each answer pool must have a unique priority value assigned to it. Answer data must
	//   be defined in the `defaultAnswerData` property for the rule and the `cases` property
	//   must not be defined.
	// - LOAD_BALANCE requires exactly an unconditional WEIGHTED rule that shuffles answers
	//   by name. Answer data must be defined in the `defaultAnswerData` property for the
	//   rule and the `cases` property must not be defined.
	// - ROUTE_BY_GEO requires exactly one PRIORITY rule that ranks answers by pool using the
	//   geographical location of the client as a condition. Within that rule you may only
	//   use `query.client.geoKey` in the `caseCondition` expressions for defining the cases.
	//   For each case in the PRIORITY rule each answer pool must have a unique priority
	//   value assigned to it. Answer data can only be defined within cases and
	//   `defaultAnswerData` cannot be used in the PRIORITY rule.
	// - ROUTE_BY_ASN requires exactly one PRIORITY rule that ranks answers by pool using the
	//   ASN of the client as a condition. Within that rule you may only use
	//   `query.client.asn` in the `caseCondition` expressions for defining the cases.
	//   For each case in the PRIORITY rule each answer pool must have a unique priority
	//   value assigned to it. Answer data can only be defined within cases and
	//   `defaultAnswerData` cannot be used in the PRIORITY rule.
	// - ROUTE_BY_IP requires exactly one PRIORITY rule that ranks answers by pool using the
	//   IP subnet of the client as a condition. Within that rule you may only use
	//   `query.client.address` in the `caseCondition` expressions for defining the cases.
	//   For each case in the PRIORITY rule each answer pool must have a unique priority
	//   value assigned to it. Answer data can only be defined within cases and
	//   `defaultAnswerData` cannot be used in the PRIORITY rule.
	// - CUSTOM allows an arbitrary configuration of rules.
	// For an existing steering policy, the template value may be changed to any of the
	// supported options but the resulting policy must conform to the requirements for the
	// new template type or else a Bad Request error will be returned.
	Template UpdateSteeringPolicyDetailsTemplateEnum `mandatory:"false" json:"template,omitempty"`

	// Simple key-value pair that is applied without any predefined name, type, or scope.
