Troubleshooting

No add-in

If you have installed Internals Viewer but there is no add-in check the following registry settings and ensure LoadBehavior is set to 1

SQL Server 2005

HKEY_CURRENT_USER\Software\Microsoft\Microsoft SQL Server\90\Tools\Shell\Addins\InternalsViewer.SSMSAddIn.Connect

SQL Server 2008

HKEY_CURRENT_USER\Software\Microsoft\Microsoft SQL Server\100\Tools\Shell\Addins\InternalsViewer.SSMSAddIn.Connect

If the LoadBehavior registry entry is missing the following files should be imported:

SQL Server 2005 - InternalsViewer20081228-90.reg
SQL Server 2008 - InternalsViewer20081228-100.reg

Project Description

Internals Viewer is a tool for looking into the SQL Server storage engine and seeing how data is physically allocated, organised and stored.

All sorts of tasks performed by a DBA or developer can benefit greatly from knowledge of what the storage engine is doing and how it works. This tool has been designed to make database internals more accessible.

Version 2 integrates with SQL Server Management Studio.

Note There was a problem with the first release of Beta 2 20081228. If no add-in is visible please follow the instructions in Troubleshooting.

DannyGould — Sun, 28 Dec 2008 17:40:08 GMT

Object Explorer Integration

Internals Viewer adds extra nodes to the Object Explorer at the Indexes level.

If an object has no indexes or is a heap (it has no clustered index) a (Heap) node is added to the list of indexes.

Indexes can be expanded to show the three entry points to the table or index.

DannyGould — Sun, 28 Dec 2008 14:28:58 GMT

Transaction Log Viewer

The Transaction Log Viewer integrates with the SQL Server Management Studio query window.

To enable the viewer check the menu option Internals Viewer – Display Transaction Log.

Note The Transaction Log Viewer uses checkpoints to monitor the transaction log. It should only be used on non-production SQL Servers as the checkpoints may cause performance issues.

When the Transaction Log Viewer is enabled an extra Transaction Log tab will be displayed in the Query Results pane.

The Transaction Log tab shows the following information:

LSN – Log Sequence Number
Operation – The transaction log operation
Context – The context of the operation
Page – The page the operation applied to. This can be clicked on the open the page in the Page Viewer.
Slot – The slot the operation applied to. This can be clicked on to open the page/slot in the Page Viewer
Allocation Unit
Description – Additional information

Green text on the Transaction Log Viewer indicates the operation is related to allocation

Gray text indicates the operation is related to a system object
