As with a nonclustered installation, you begin a failover clustering installation by running setup.exe from the installation DVD. Next, you go through a series of steps to install setup support files and check various setup rules. As shown in figure 5.9, the setup checks for a clustered installation are more detailed than for a nonclustered installation. Installation continues with the usual prompts for a product key, acknowledgment of license terms, and feature selection, before arriving at the instance configuration step, as shown in figure 5.10. The one difference between this step and the equivalent step in a nonclustered installation is the SQL Server Network Name field. The name you enter is used to identify an instance on the network. In our example, we ll use BNE-SQL-PR-02 as our network name, and together with the instance name (Marketing), we ll access this

Figure 11.6 The Copy Files tab lets you specify the log backup copy location, frequency, and retention period.

Figure 11.7 Figure The Restore Transaction Log tab allows you to set the restore frequency along with the database state between restores.

Note that when using standby mode, you must take into account the restore frequency. The default restore frequency of 15 minutes is inappropriate for a reporting solution, as users would be disconnected (if the disconnect option is chosen) every 15 minutes to enable the log restore. For our example, we ve chosen a 12-hour restore frequency. This will enable 12 hours of uninterrupted reporting before the next restore, and assuming users are advised on the restore times, such a configuration may be quite acceptable. Regardless of the restore frequency, the backup and copy jobs have their own independent schedules. In our example, the backup and copy jobs run every 15 minutes. If the secondary database is required in an emergency, the restore process accessible via a SQL Server Agent job created by the log shipping setup process can be manually executed at any time, which will restore any outstanding transaction logs and thus bring the secondary server up to date. Once you complete these steps, click OK to return to the screen shown in figure 11.3. The other log shipping component for consideration is the monitoring instance, which will actively monitor (via SQL Server Agent jobs) the backup, copy, and restore progress. If any of these events don t run within the specified intervals, the monitoring server generates alerts, which can be configured to notify the appropriate DBAs. We ll cover alerts in more detail in chapter 14.
