通过ARM启用Azure SQL数据库自动调整

Question

我无法找到任何关于在发布管道中启用自动调整的文档,即通过ARM模板或powershell,也不能在github arm快速入门中找到.

我可以在资源浏览器中看到自动调优,但我没有看到这在ARM模板中如何反映.

{
  "name": "Microsoft.Sql/servers/automaticTuning/read",
  "display": {
    "provider": "Microsoft SQL Database",
    "resource": "Server Automatic Tuning",
    "operation": "Get automatic tuning settings for the server",
    "description": "Returns automatic tuning settings for the server"
  }
},
{
  "name": "Microsoft.Sql/servers/automaticTuning/write",
  "display": {
    "provider": "Microsoft SQL Database",
    "resource": "Server Automatic Tuning",
    "operation": "Update automatic tuning settings for the server",
    "description": "Updates automatic tuning settings for the server and returns updated settings"
  }
},

现在可以在逻辑服务器或数据库级别通过ARM模板设置自动调整选项。我已使用Automation ScriptAzure门户上的刀片服务器获取以下信息：Sql服务器级别：

{
  "type": "Microsoft.Sql/servers/advisors",
  "name": "[concat(parameters('sqlserverName'), '/', 'ForceLastGoodPlan')]",
  "apiVersion": "2014-04-01",
  "scale": null,
  "properties": {
    "autoExecuteValue": "Enabled"
  },
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]"
  ]
},
{
  "type": "Microsoft.Sql/servers/advisors",
  "name": "[concat(parameters('sqlserverName'), '/', 'CreateIndex')]",
  "apiVersion": "2014-04-01",
  "scale": null,
  "properties": {
    "autoExecuteValue": "Enabled"
  },
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]"
  ]
},
{
  "type": "Microsoft.Sql/servers/advisors",
  "name": "[concat(parameters('sqlserverName'), '/', 'DropIndex')]",
  "apiVersion": "2014-04-01",
  "scale": null,
  "properties": {
    "autoExecuteValue": "Enabled"
  },
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]"
  ]
},
{
  "type": "Microsoft.Sql/servers/advisors",
  "name": "[concat(parameters('sqlserverName'), '/', 'DbParameterization')]",
  "apiVersion": "2014-04-01",
  "scale": null,
  "properties": {
    "autoExecuteValue": "Disabled"
  },
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]"
  ]
},
{
  "type": "Microsoft.Sql/servers/advisors",
  "name": "[concat(parameters('sqlserverName'), '/', 'DefragmentIndex')]",
  "apiVersion": "2014-04-01",
  "scale": null,
  "properties": {
    "autoExecuteValue": "Disabled"
  },
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]"
  ]
}

数据库级别：

{
    "type": "Microsoft.Sql/servers/databases/advisors",
    "name": "[concat(parameters('sqlserverName'), '/', parameters('databaseName'), '/', 'ForceLastGoodPlan')]",
    "apiVersion": "2014-04-01",
    "scale": null,
    "properties": {
    "autoExecuteValue": "Enabled"
    },
    "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]",
    "[resourceId('Microsoft.Sql/servers/databases', parameters('sqlserverName'), parameters('databaseName'))]"
    ]
},
{
    "type": "Microsoft.Sql/servers/databases/advisors",
    "name": "[concat(parameters('sqlserverName'), '/', parameters('databaseName'), '/', 'CreateIndex')]",
    "apiVersion": "2014-04-01",
    "scale": null,
    "properties": {
    "autoExecuteValue": "Enabled"
    },
    "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]",
    "[resourceId('Microsoft.Sql/servers/databases', parameters('sqlserverName'), parameters('databaseName'))]"
    ]
},
{
    "type": "Microsoft.Sql/servers/databases/advisors",
    "name": "[concat(parameters('sqlserverName'), '/', parameters('databaseName'), '/', 'DropIndex')]",
    "apiVersion": "2014-04-01",
    "scale": null,
    "properties": {
    "autoExecuteValue": "Enabled"
    },
    "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]",
    "[resourceId('Microsoft.Sql/servers/databases', parameters('sqlserverName'), parameters('databaseName'))]"
    ]
},
{
    "type": "Microsoft.Sql/servers/databases/advisors",
    "name": "[concat(parameters('sqlserverName'), '/', parameters('databaseName'), '/', 'DbParameterization')]",
    "apiVersion": "2014-04-01",
    "scale": null,
    "properties": {
    "autoExecuteValue": "Disabled"
    },
    "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]",
    "[resourceId('Microsoft.Sql/servers/databases', parameters('sqlserverName'), parameters('databaseName'))]"
    ]
},
{
  "type": "Microsoft.Sql/servers/databases/advisors",
  "name": "[concat(parameters('sqlserverName'), '/', parameters('databaseName'), '/DefragmentIndex')]",
  "apiVersion": "2014-04-01",
  "scale": null,
  "properties": {
    "autoExecuteValue": "Disabled"
  },
  "dependsOn": [
    "[resourceId('Microsoft.Sql/servers', parameters('sqlserverName'))]",
    "[resourceId('Microsoft.Sql/servers/databases', parameters('sqlserverName'), parameters('databaseName'))]"
  ]
}

Alex，正如 Estienne 提到的，目前 ARM 模板不支持这一点，但有其他方法可以做到这一点。

1) 所有新创建的数据库，默认都会继承服务器的自动调整设置。因此，如果您在服务器级别配置自动调整，则所有新数据库将在创建时继承这些设置。

2）您可以使用T-SQL，您可以在数据库上运行来配置自动调整。以下 T-SQL 将在数据库级别配置自动调整：

ALTER DATABASE current SET AUTOMATIC_TUNING = AUTO | INHERIT | CUSTOM

选择 AUTO，您将获得一组默认选项 - 启用 CREATE_INDEX 和 FORCE_LAST_GOOD_PLAN。选择 INHERIT 您将从服务器继承设置。选择 CUSTOM，您将需要明确说明所有自动调整选项。

如果您想显式启用/禁用某些选项，可以使用以下命令：

ALTER DATABASE current SET AUTOMATIC_TUNING ( FORCE_LAST_GOOD_PLAN = DEFAULT, CREATE_INDEX = ON, DROP_INDEX = OFF )

将某些选项设置为 DEFAULT 将采用数据库级别配置。

3）您可以使用REST API来配置自动调优。像这样的东西：
PATCH /subscriptions/{SUBID}/resourceGroups/{RGNAME}/providers/Microsoft.Sql/servers/{SRVNAME}/databases/{DBNAME}/automaticTuning/current?api-version=2017-03-01-预览 HTTP/1.1
主机：management.azure.com
授权：承载
内容类型：application/json
缓存控制：无缓存
{ "properties": { "desiredState": "Custom", "options": { "forceLastGoodPlan" ：“开”，“createIndex”：“开”，“dropIndex”：“关”}}}

很快您就可以通过 PowerShell 和托管库进行配置。

尽管存在基础设施，但目前尚未正式支持此功能。我们正在努力在不久的将来为其提供支持。
