set long 100000 longchunksize 100000 linesize 120 print :report During the compare and analysis phase, you can do the following: Calculate the impact of the change on specific SQL statements. Calculate the impact of the change on the SQL workload as a whole. Assign weights to important SQL statements in the workload. Detect performance regression and improvements. Detect changes in the execution plans of the SQL statements. Recommend the running of the SQL Tuning Advisor to tune regressed SQL statements. You can use the following views when working with the SQL Performance Analyzer: DBA_ADVISOR_TASKS shows details about the analysis task. DBA_ADVISOR_FINDINGS shows analysis findings, which are classified as performance regression, symptoms, informative messages, and errors. DBA_ADVISOR_EXECUTIONS shows metadata information for task executions. DBA_ADVISOR_SQLPLANS shows a list of SQL execution plans. DBA_ADVISOR_SQLSTATS shows a list of SQL compilation and execution statistics.

The SQL Performance Analyzer contains both a result summary and a result details section. The former shows quickly whether the database upgrade in our example will result in any performance deterioration or improvement. The advisor also provides recommendations to avoid any potential performance deterioration. Since the SQL Performance Analyzer is an integral part of the Oracle database, it can take advantage of tools such as the SQL Tuning Advisor as well as features such as SQL Plan Management to finetune database performance.
APPENDIX
Oracle Database 11g SQL and PL/SQL: A Brief Primer
m sure most of you are already familiar with SQL to some extent. However, I present in this appendix a quick introduction to Oracle Database 11g SQL and its programmatic cousin, PL/SQL, as a starting point for those new to programming Oracle databases. My goal here is simply to present a short summary of the classic DML and DDL commands and to discuss the newer SQL and PL/SQL concepts in greater detail. Your need to know SQL or PL/SQL depends somewhat on the type of DBA you are a production support DBA won t need to know as much about Oracle programming as a DBA assisting in developmental efforts. It s becoming increasingly important, however, for DBAs to learn a number of advanced SQL and PL/SQL concepts, including the new Java and XML-based technologies. The reason is simple: even when you aren t developing applications yourself, you re going to be assisting people who are doing so, and it helps to know what they re doing. This appendix aims to summarize some of the most important Oracle Database 11g SQL and PL/SQL features so you and the developers you work with can take advantage of them. Oracle SQL and PL/SQL represent an enormously broad topic, so this appendix lightly covers several important topics without attempting any detailed explanation due to space considerations. Please refer to the Oracle manuals Application Developer s Guide Fundamentals and PL/SQL User s Guide and Reference for a comprehensive introduction to SQL and PL/SQL.
