Oracle is a SQL processing engine and the execution speed of any SQL query is influenced by many factors, both internal and external. As a declarative data access method, SQL relies on the Oracle cost-based optimizer to always choose the "best" execution plan for every SQL query. However, Oracle's SQL is among the most flexible and robust in the world, and along with this great power comes complexity. Tuning Oracle SQL is the single most important skill of any Oracle professional, and Oracle professionals are challenged to create SQL statements that will support thousands of concurrent executions with sub-second response time. This book is the culmination of the author's 25 years of full-time DBA experience and he shares expert tips and secrets for hyper charging SQL execution speed. This book covers advanced topics and it is not appropriate for beginners, dilettantes or neophytes. Don is a popular lecturer and teacher and is a frequent speaker at Oracle OpenWorld and other international database conferences.

Burleson loves to collect antiques and has taken extensive classes in antique identification and appraisal.

Generate all potential execution plans list. But a 3. Calculate each execution plan cost using all available object standard SQL delete may result in honey comb fragmentation statistics.

Selecting execution plan of the lowest cost. Full Table Scan may arise due to reduce intra block fragmentation.

So if the primary goal is performance we should option can be used for super fast rebuild of index. On the push the rules of data integrity into application layer. A fair occasion if nologging is used it neccessitates re-running the design of database evades foreign key constraints.

Many of the create index query, if we do a roll-forward recovery of major RDBMS have a set of tables referred as system tables, database. Table 3. This is a kind of a concurrent concurrence for faster index rebuilds.

B-tree indexes, which reduces index height and improves 6 Table Partitioning: Partitioning impressively enhances indexed queries performance. We can use the large blocksize delete performance. This is due to the reason that sequence 26 Alter table join order: In the case of successive read key is every time high order key.

Every insertion of low-level waits, SQL can be tweaked to alter the sequence in which index tree node should spread upwards towards high-key tables are joined i.

We should perform these tuning Hints can be passed to optimizer, to enforce some actions, tasks only if their exists delay events which are straightly such as compelling to use a specific method or use particular associated with index block contention. The following can index. Higher SQL execution plans, resulting in needless disk waits.

The memory enables sorting and other operations faster. In addition if column data values are skewed, adding Tuning Physical Read Waits histograms may also be essential. A Surrogate Key could be a system the wait event is experienced in database. Utilizing e Space Management pages: Locally managed this temporal data, a DBA can recognize concealed tablespace and Automatic Segment Space performance issues and predict the performance problems Management consume less pages inside a even prior they harm the database.

By utilizing verified predicting methods, we can create f Blocksize: Enforce smaller block size to reduce self-tuning DBMS engine that predicts and expects wasting space, nonetheless we have to remember performance variations and enforces just-in-time tweaking that optimum size of block is a job of row length i. RBO: If a tie up exists when evaluating 35 Tuning Workload: We should tune our workload performance of multiple queries using CBO, then evaluate comprehensively by enhancing parameters of the optimizer queries using RBO analysis.

Utilizing GIGO garbage-in, garbage-out norm, we code may be spread across several machines. Enforce created with too little hash keys, then each key will split over histograms providently when there is requisite in assisting multiple blocks negating the advantages of cluster.
