CHAPTER 14 DATABASE MAINTENANCE 325 CPU UTILIZATION 100% 75% 50% 25% 0% Mon Tue Wed Thu Fri Sat Sun Figure 14-3. CPU utilization graph produced from the data in the table There is a wealth of other useful data in the STATSPACK tables. For example, offers cumulative values of Oracle metrics such as logical reads and physical reads, reports the time spent waiting for I/O, locks, and other resources, and offers summary information such as the total of the elapsed times of all SQL queries processed by Oracle. Patching Oracle periodically releases fixes, known as patches, for software bugs. A one- off patch is a fix for an individual bug, while a patchset is a collection of numerous bug fixes. A critical patch update (CPU) is a collection of fixes for security- related bugs; Oracle releases one such CPU every quarter. A patchset has an Oracle database version string associated with it; for example, 10.2.0.4 is a patchset associated with Oracle 10g Release 2. By contrast, one- off patches and CPUs are identified by a single number; for example, 7210195 is the number of the July 2008 CPU. One- off patches, patches, and patchsets can be downloaded from the Patches & Updates section of the Metalink customer portal. Some organizations adopt a policy of applying software patches and CPUs whenever they become available. Listing 14-12 is a typical notice regarding the availability of a new CPU that you will receive from Oracle if you have a support contract.
326 CHAPTER 14 DATABASE MAINTENANCE Listing 14-12. Notification about a Critical Patch Update (CPU) The notification about a critical patch update directs readers to a web page where they can find more information. Once you have determined the specific patch number applicable to your operating system platform, you can download the CPU from the Patches & Updates section of the Metalink customer portal, as illustrated in Figure 14-4.
