45. Verify that both Node1 and Node 2 are off, and then start Node1. 46. Log onto Node1, and launch Cluster Administrator. 47. From the drop-down list, choose Create New Cluster, and click OK. 48. Click Next, verify that your domain name is specified correctly in the top dropdown list, and enter Clust1 as the Cluster Name. Click Next. 49. Node1 should be specified by default for the Computer Name. Click Next. 50. The wizard now analyzes Node1 to verify that it is compatible for clustering. When the analysis completes and displays a green bar, click Next. 51. Enter an IP address for the cluster on the Public segment. Based on the sug gested settings specified at the beginning of this chapter, set it to 10.1.1.5. Click Next. 52. Enter clusteradmin for the User Name, enter the password that you used for this account, verify that the domain name is specified correctly, and click Next. 53. Click Quorum, and ensure that Disk Q is specified for the quorum. If not, change the entry and click OK.

When you configure a cluster on physical hardware, the disk that the New Server Cluster Wizard selects by default as the quorum is the first disk added to Node1 that is not a locally attached disk. Virtual Server selects the first drive letter in alphabetical order. You can use the Cluster Configuration Quorum dialog box to specify a local quorum that is used when build ing a single node cluster for testing. This dialog box is also where you can change the type of cluster from the standard cluster you are building to a majority node set cluster by choos ing Majority Node Set in this menu. If you choose Majority Node Set, the New Server Cluster Wizard creates a quorum database on each node in the cluster.

SQL Server 2005 retains the SET ROWCOUNT statement. The SET ROWCOUNT value overrides the SELECT statement TOP keyword if the ROWCOUNT is the smaller value. Some instances exist (for example, rows returned from an unsorted heap) where the TOP operator is more efficient than using SET ROWCOUNT. Because of this, Microsoft recommends using the TOP operator rather than SET ROWCOUNT to limit the number of rows returned by a query.

54. Verify that all settings are correct, and click Next. 55. The next step in the process takes a few minutes as the cluster is built to your specifications. When this process completes, click Next, and then click Finish. 56. Congratulations; you have created a Windows cluster! 57. Verify that you have created three groups: Cluster Group contains Cluster Name, Cluster IP Address, and Disk Q; Group 0 contains Disk M; Group 1 contains Disk N. 58. With Node1 running, start Node2. 59. Within Cluster Administrator, right-click Clust1; choose New and then Node. Click Next when the Add Nodes Wizard starts. 60. Specify Node2 as the computer name, click Add, and then click Next. 61. After the analysis completes, click Next. 62. Enter the password for the clusteradmin account, and then click Next. 63. Verify configuration settings, and then click Next. 64. Node2 is now configured for clustering and added to Clust1. 65. Click Next, and then click Finish.

15. Notice that in this table, the last three rows are associated with our newly created partition. The table was partitioned into three groups of the following sizes: 137, 204, and 163. Exercise 2: Create a CLR User-Defined Function In this exercise, you will create a user-defined function using .NET Framework code. The code will be created using a Windows text-based editor and compiled using the Visual Basic or C# command line compiler. You will then create an assembly in SQL Server and execute the newly created user-defined function just as you would a user-defined function created with Transact-SQL.

Because of the way Virtual Server handles disk resources internally, you can receive some warnings when a cluster is configured. This is normal and does not affect the operation of your cluster. As long as you do not receive an error (the progress bar turns red), your config uration has succeeded, and you have a fully functional cluster.

67. Select the Cluster Group group. Right-click Cluster Name, and choose Take Offline. Right-click Cluster IP Address, and choose Take Offline. 68. From the File menu, choose New and then Resource. 69. Specify a name of MS DTC, select Distributed Transaction Coordinator for the Resource Type, and verify that Cluster Group is selected for the Group. Click Next. 70. Verify that both Node1 and Node2 are specified as Possible Owners, and click Next. 71. Add Cluster Name and Disk Q to the Resource Dependencies. Click Finish. 72. Right-click Cluster Group, and choose Bring Online.

For demonstration purposes, the user-defined function in this exercise performs a data access query. Generally, you will not use SQLCLR for basic data access. In this case, Transact-SQL is a better alternative.
