Title: SQL Server Resource Governor Setup
Author: user
with SQL Server 2019, i would like to use resource governer to limit the active directory group us1\Risk to use no mre than 40% memory, and no more than 40% cpu. can you script that out?

Author: ChatGPT
To configure Resource Governor in SQL Server 2019 to limit memory and CPU for the Active Directory group `us1\Risk`, you'll need to follow these steps:

1. Create a workload group.
2. Create a resource pool.
3. Associate the workload group with the resource pool.
4. Create a classifier function to map sessions from the AD group to the workload group.
5. Enable Resource Governor.

Here's a script that outlines this process:

```sql
-- Step 1: Enable Resource Governor (if not already enabled)
ALTER RESOURCE GOVERNOR RECONFIGURE;

-- Step 2: Create a resource pool that limits memory and CPU to 40%
CREATE RESOURCE POOL RiskPool
WITH
(
    MAX_MEMORY_PERCENT = 40, -- Memory cap
    MAX_CPU_PERCENT = 40     -- CPU cap
);

-- Step 3: Create a workload group that will be associated with the resource pool
CREATE WORKLOAD GROUP RiskGroup
USING RiskPool
WITH
(
    IMPORTANCE = MEDIUM,
    REQUEST_MAX_MEMORY_GRANT_PERCENT = 40  -- Memory grant for queries
);

-- Step 4: Create a classifier function to map the AD group to the RiskGroup
-- This function assigns sessions from AD group 'us1\Risk' to the workload group
CREATE FUNCTION dbo.ResourceGovernorClassifier()
RETURNS SYSNAME
WITH SCHEMABINDING
AS
BEGIN
    DECLARE @WorkloadGroup SYSNAME = 'default';

    -- Check if the user is a member of the AD group us1\Risk
    IF IS_MEMBER('us1\Risk') = 1
    BEGIN
        SET @WorkloadGroup = 'RiskGroup'; -- Assign to RiskGroup
    END

    RETURN @WorkloadGroup;
END;

-- Step 5: Register the classifier function with Resource Governor
ALTER RESOURCE GOVERNOR
WITH (CLASSIFIER_FUNCTION = dbo.ResourceGovernorClassifier);

-- Step 6: Apply and reconfigure Resource Governor to activate the new settings
ALTER RESOURCE GOVERNOR RECONFIGURE;
```

### Explanation:
- **Resource Pool (`RiskPool`)**: This limits both CPU and memory to 40%.
- **Workload Group (`RiskGroup`)**: This is associated with the `RiskPool` and provides an additional control for memory grants.
- **Classifier Function (`dbo.ResourceGovernorClassifier`)**: This function checks if the session is initiated by a user in the AD group `us1\Risk`. If true, it assigns the session to the `RiskGroup`.
- **Reconfigure**: The `ALTER RESOURCE GOVERNOR RECONFIGURE` command applies the changes.

After running this script, members of the `us1\Risk` AD group will have their memory and CPU usage restricted to 40%.

i get a syntax issue with this command: -- Step 3: Create a workload group that will be associated with the resource pool
CREATE WORKLOAD GROUP RiskGroup
USING RiskPool
WITH
(
    IMPORTANCE = MEDIUM,
    RE

Author: ChatGPT
It seems like the issue might be caused by an incomplete `WITH` clause in your `CREATE WORKLOAD GROUP` statement. Here's the correct syntax for the `CREATE WORKLOAD GROUP` statement in SQL Server:

```sql
-- Step 3: Create a workload group that will be associated with the resource pool
CREATE WORKLOAD GROUP RiskGroup
USING RiskPool
WITH
(
    IMPORTANCE = MEDIUM,
    REQUEST_MAX_MEMORY_GRANT_PERCENT = 40  -- Memory grant for queries
);
```

The likely cause of the error is that the `WITH` clause was cut off at `RE`, leading to an incomplete or invalid query.

Try running the complete version above. Let me know if you encounter any other issues!

i had an incomplete paste, but the command you provided for step 3 returns this syntax error:  Msg 319, Level 15, State 1, Line 15
Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon.
M

Author: ChatGPT
In SQL Server, certain statements (like `CREATE WORKLOAD GROUP`) need to be preceded by a semicolon if they follow another statement. The error message you encountered suggests that SQL Server expects a semicolon before the `WITH` clause to separate it from the previous statement.

To fix this, simply add a semicolon before the `WITH` clause, like this:

```sql
-- Step 3: Create a workload group that will be associated with the resource pool
CREATE WORKLOAD GROUP RiskGroup
USING RiskPool
WITH
(
    IMPORTANCE = MEDIUM,
    REQUEST_MAX_MEMORY_GRANT_PERCENT = 40  -- Memory grant for queries
);
```

If you still encounter the same issue, it's possible there's an earlier statement in the script that wasn't properly terminated. To resolve that, add a semicolon (`;`) after any preceding statements (such as the `CREATE RESOURCE POOL`).

For example:

```sql
-- Step 2: Create a resource pool
CREATE RESOURCE POOL RiskPool
WITH
(
    MAX_MEMORY_PERCENT = 40,
    MAX_CPU_PERCENT = 40
);
-- Make sure previous statements are terminated properly

-- Step 3: Create a workload group
CREATE WORKLOAD GROUP RiskGroup
USING RiskPool
WITH
(
    IMPORTANCE = MEDIUM,
    REQUEST_MAX_MEMORY_GRANT_PERCENT = 40
);
```

Let me know if this resolves the issue!

it looks like the USINg statement belongs AFTER the with statement; would this be correct? -- Step 3: Create a workload group that will be associated with the resource pool
CREATE WORKLOAD GROUP RiskGroup
WITH
(
    IMPORTANCE = MEDIUM,
    REQUEST_MAX_MEMORY_GRANT_PERCENT = 40  -- Memory grant for queries
)
USING RiskPool;

Lowell is working with SQL Server Resource Governor in SQL Server 2019 to limit memory and CPU usage for an Active Directory group.

Author: tool
Model set context updated.

Author: ChatGPT
Yes, you're absolutely correct! In SQL Server, the `WITH` clause should precede the `USING` clause when creating a workload group. The corrected syntax for creating the workload group should be:

```sql
-- Step 3: Create a workload group that will be associated with the resource pool
CREATE WORKLOAD GROUP RiskGroup
WITH
(
    IMPORTANCE = MEDIUM,
    REQUEST_MAX_MEMORY_GRANT_PERCENT = 40  -- Memory grant for queries
)
USING RiskPool;
```

This should resolve the syntax error. Let me know how it goes!

can any of the reporting server executables script out the current shared data sources, configuration, even without the password?

Author: ChatGPT
Yes, SQL Server Reporting Services (SSRS) allows you to script out the current shared data sources and their configuration, although the password will not be included as it is securely stored. You can do this using the `rs.exe` utility, PowerShell scripts, or querying the ReportServer database directly.

### Option 1: Using `rs.exe` (Reporting Services Scripting Utility)
You can create a script using the `rs.exe` utility to list shared data sources. This utility lets you interact with the SSRS web service and extract items like shared data sources.

Here's an example of a VBScript that can be run via `rs.exe` to export the shared data sources:

1. Create a file named `ExportDataSources.rss` with the following content:

```vbscript
Public Sub Main()
    ' Get all the items in the SSRS catalog
    Dim items As CatalogItem() = rs.ListChildren("/", True)

    ' Iterate through each item and check for Data Source type
    For Each item As CatalogItem In items
        If item.TypeName = "DataSource" Then
            ' Output the data source details
            Console.WriteLine("Name: " & item.Name)
            Console.WriteLine("Path: " & item.Path)
            
            ' Get data source definition
            Dim dataSource As DataSourceDefinition = rs.GetDataSourceContents(item.Path)
            Console.WriteLine("Extension: " & dataSource.Extension)
            Console.WriteLine("ConnectString: " & dataSource.ConnectString)
            Console.WriteLine("UserName: " & dataSource.UserName)
            ' Password will not be returned for security reasons
            Console.WriteLine("------")
        End If
    Next
End Sub
```

2. Run the script using `rs.exe`:

```cmd
rs.exe -i ExportDataSources.rss -s http://<YourReportServer>/ReportServer
```

This script will list the shared data sources with their connection strings and usernames but will not show the password for security reasons.

### Option 2: Querying the ReportServer Database
You can also query the SSRS database directly to extract information about the shared data sources. Here is a query that retrieves shared data source information:

```sql
SELECT 
    C.Name AS DataSourceName,
    C.Path AS DataSourcePath,
    DS.ConnectString,
    DS.CredentialRetrieval,
    DS.UserName,
    DS.UseOriginalConnectString
FROM 
    ReportServer.dbo.DataSource DS
JOIN 
    ReportServer.dbo.Catalog C ON DS.ItemID = C.ItemID
WHERE 
    C.Type = 5 -- Type 5 represents Data Source
```

This query will return the names, paths, and connection strings of the shared data sources. Like before, the password will not be visible.

### Option 3: PowerShell Script
You can also use PowerShell along with the SSRS web service API to extract the shared data sources. Here's a basic example:

```powershell
$ReportServerUri = "http://<YourReportServer>/ReportService2010.asmx"
$ssrs = New-WebServiceProxy -Uri $ReportServerUri -Namespace SSRS -UseDefaultCredential

$items = $ssrs.ListChildren("/", $true)
foreach ($item in $items) {
    if ($item.TypeName -eq "DataSource") {
        Write-Host "Data Source: " $item.Name
        Write-Host "Path: " $item.Path

        $dataSourceDefinition = $ssrs.GetDataSourceContents($item.Path)
        Write-Host "Connection String: " $dataSourceDefinition.ConnectString
        Write-Host "UserName: " $dataSourceDefinition.UserName
        Write-Host "------"
    }
}
```

Run this PowerShell script, and it will print out the shared data sources along with their connection strings.

can you convert that so that powershell calls the executable instead

Author: ChatGPT
To modify the PowerShell script so that it uses the `rs.exe` executable to call the Reporting Services Scripting Utility, you'll need to run `rs.exe` from PowerShell and pass the VBScript file to it. Here's how you can set this up:

### Steps:

1. **Create the RSS script file** (VBScript for `rs.exe`):
   Save the following code into a file, e.g., `ExportDataSources.rss`.

   ```vbscript
   Public Sub Main()
       ' Get all the items in the SSRS catalog
       Dim items As CatalogItem() = rs.ListChildren("/", True)

       ' Iterate through each item and check for Data Source type
       For Each item As CatalogItem In items
           If item.TypeName = "DataSource" Then
               ' Output the data source details
               Console.WriteLine("Name: " & item.Name)
               Console.WriteLine("Path: " & item.Path)

               ' Get data source definition
               Dim dataSource As DataSourceDefinition = rs.GetDataSourceContents(item.Path)
               Console.WriteLine("Extension: " & dataSource.Extension)
               Console.WriteLine("ConnectString: " & dataSource.ConnectString)
               Console.WriteLine("UserName: " & dataSource.UserName)
               ' Password will not be returned for security reasons
               Console.WriteLine("------")
           End If
       Next
   End Sub
   ```

2. **Modify PowerShell script to call `rs.exe`**:
   You can now call `rs.exe` from PowerShell using the `Start-Process` cmdlet. Here???s the PowerShell script:

   ```powershell
   # Define paths and server URL
   $rsExePath = "C:\Program Files\Microsoft SQL Server\Reporting Services\RS_Exec\rs.exe"
   $rssScriptPath = "C:\path\to\ExportDataSources.rss"  # Adjust this path
   $reportServerUrl = "http://<YourReportServer>/ReportServer"  # Replace with your report server URL

   # Create the argument string for rs.exe
   $arguments = "-i $rssScriptPath -s $reportServerUrl"

   # Run the rs.exe process
   Start-Process -FilePath $rsExePath -ArgumentList $arguments -Wait -NoNewWindow

   # Output to inform user that process has completed
   Write-Host "Finished running ExportDataSources.rss via rs.exe."
   ```

### Breakdown:
- **`$rsExePath`**: Path to the `rs.exe` executable. Update it based on your SSRS installation path.
- **`$rssScriptPath`**: Path to the RSS script file (`ExportDataSources.rss`) you created.
- **`$reportServerUrl`**: URL to your SSRS report server.
- **`Start-Process`**: This runs `rs.exe` with the necessary arguments, waits for completion, and doesn't open a new window.

### Example Command Execution:
If the `rs.exe` and the script are configured correctly, executing the PowerShell script will call `rs.exe` and run the `ExportDataSources.rss` script, exporting your shared data source information.
