4 PL/SQL Use PL/SQL Hierarchical Profiler to identify hot spots Callee Elapsed Aggregated OE_API 3, ,781 get_order 8, ,712 get_order static SQL line 12 7,159 7,159 get_order static SQL line , ,948 place_order place_order static SQL line See where your CPU time is going Hierarchical profiler shows context Invoke using DBMS_HPROF.START_PROFILING

5 Edition-Based Redefinition Online Application Upgrade Application v1 Base Edition Database objects Application v2 New Edition Allows multiple editions to be available simultaneously Compilation of editioned objects transparent to application Views, Synonyms and PL/SQL objects can be editioned

6 Edition-Based Redefinition Online Application Upgrade Application v1 Application v2 2 3 View Base Edition Procedure View Procedure 1 New Edition 4 Table New Column 1 Compile objects in new edition without affecting online users 2 Deploy new application version referencing new edition 3 Current users are not effected, they reference base edition 4 Phase in new application version over time

7 XML DB Manage XML Content within the Oracle Database Oracle Database XML XML Consolidate storage of relational and XML data in Oracle 11g Natively store XML content XMLTYPE columns XML Tables Index of XML for fast access Unload relational data to XML Use XML Standards including XQuery and XML Schema

8 XML DB Example Query XML Data in XMLTYPE Columns select xtab.year, d.dname, xtab.actual, xtab.estimate from WWV_DEMO_DEPT d, XMLTable ('/Budget/History/Budget' passing BUDGET COLUMNS YEAR VARCHAR2(4) PATH 'Year', ESTIMATE NUMBER(20) PATH 'Estimate', ACTUAL NUMBER(20) PATH 'Actual') xtab Year Department Estimate Actual 2010 Accounting 570, , Operations 255, , Accounting 540, , Operations 240, ,000

9 XML DB - Example Use SQL to Unload Relational Data to XML select xmlelement("department", xmlattributes( d.deptno as "DepartmentId"), xmlelement("name", d.dname), xmlelement("employees, ( select xmlagg( xmlelement("employee", xmlforest(e.ename as "Name", e.hiredate as "StartDate ) ) ) from EMP e where e.deptno = d.deptno) )) as XML from DEPT d XML <Department DepartmentId="10"> <Name>ACCOUNTING</Name> <Employees> <Employee employeeid="7782"> <Name>CLARK</Name> <StartDate> </StartDate> </Employee> <Employee employeeid="7839"> <Name>KING</Name> <StartDate> </StartDate> </Employee> <Employee employeeid="7934"> <Name>MILLER</Name> <StartDate> </StartDate> </Employee> </Employees>

10 SQL Analytics Industry s most complete implementation SQL Analytics Statistics Ranking functions Window Aggregate functions LAG/LEAD functions Reporting Aggregate functions Statistical Aggregates Linear Regression Descriptive Statistics Correlations Cross Tabs Hypothesis Testing Distribution Fitting

11 SQL Analytics - Example Listing values of a Group By column select deptno, listagg( ename, '; ' ) within group(order by ename) as department_employees from emp group by deptno DEPTNO DEPARTMENT EMPLOYEES 10 CLARK; KING; MILLER 20 ADAMS; FORD; JONES; SCOTT; SMITH 30 ALLEN; BLAKE; JAMES; MARTIN; TURNER; WARD

12 SQL Analytics - Example Referencing Previous Row Values select application, to_char(run_date, day ) run_date, rows_processed, rows_processed - lag(rows_processed, 1, 0) over (order by rows_processed )as difference from application_log order by run_date Application Run Date Rows Processed Difference Daily Load Monday Daily Load Tuesday Daily Load Wednesday Daily Load Thursday Daily Load Friday

13 SQL PIVOT Rotate rows into columns and vice versa PROD QUARTER AMOUNT Shoe s Shoe s Q Q Jeans Q Jeans Q3 500 Jeans Q3 100 Jeans Q select * from sales pivot (sum(amount) for quarter in Q1, Q2, Q3, Q4 ); PROD Q1 Q2 Q3 Q4 Shoes Null Null Jeans 1000 Null Create aggregated cross-tabular result set Project many columns as filtered summaries of one column New syntax PIVOT and UNPIVOT

14 Oracle Database JVM Write Database Stored Procedures in Java Load Java in the database and expose via PL/SQL Leverage native and open source Java functionality Run Java where it makes the most sense Provide features not native to PL/SQL Complements Java deployed in the Mid Tier Improve performance of data heavy Java Leverage Java Skills New in Oracle Database 11gR1 JIT Compiler Java Management Extensions (JMX)

15 Oracle Database JVM Write Database Stored Procedures in Java Create or replace public class Hello { static public void world() { System.out.println("Hello World"); return; } } / create or replace procedure hello as language java name Hello.world() ;

16 Additional Database Technologies OLAP Cubes Java Stored Procedures Oracle Spatial Oracle Text Multimedia Virtual Private DB

18 Database Caching Technologies SQL Result Set Cache Cache queries and sub queries Shared by all sessions Full consistency and proper semantics 2x - 100x speedup PL/SQL Function Cache Automatic invalidation Shared by all sessions Use for deterministic functions

19 SQL Result Set Cache Query Annotation and Alter Table Syntax Query Annotation Syntax select /*+ result_cache */ ename, job from employees where deptno in (10,30,40); Table Level Result Set Caching alter table employees result_cache (mode force);

20 PL/SQL Function Cache Example CREATE FUNCTION format_name ( p_first_name IN VARCHAR2, p_last_name IN VARCHAR2) RETURN VARCHAR2 RESULT_CACHE IS v_name VARCHAR2(4000) BEGIN RETURN p_first_name ' ' p_last_name; END format_name;

21 Database Caching Technologies Client Result Cache Recommended for small readintensive tables 6X reduction in CPU usage 15% to 20% in response time Invoked by setting the init.ora parameters Flash Buffer Cache Database Smart Cache Extends SGA buffer cache Smart database caching Solaris and Oracle Enterprise Linux only

22 TimesTen In-Memory Database Cache In-memory RDBMS for real-time applications Applications: Financial and Telco Services, Web Portal, CRM IMDB Cache Grid Application Application TimesTen DB TimesTen DB Fast, consistent response time with low latency Standard SQL and PL/SQL Cache subsets with read/ write; tables, rows, columns Automatic synchronization with Oracle Database Built-in high availability (HA) and data persistence Scale-out cache grid

23 TimesTen In-Memory Database Cache Flexible Cache Group Configuration Application Transactions Cache Groups Full relational access with transaction support. Automatic Data Synchronization CREATE Asynchronous Writethrough Cache Group custcache FROM customer ( cust_id (number(10,0),.. ), acct ( acct_id,.., foreign key (cust_id), orders (..);

25 Advanced Compression Option Significant reductions in data volumes 3x 10x 20x No Compression OLTP Data Warehousing Archival Benefits for both OLTP and DW solutions Transparent to the application and works with all data types EBS queries run 250% faster DML operations are 3% slower

26 Advanced Compression Syntax Example CREATE TABLE employees( emplyee_id NUMBER, first_name VARCHAR2(50), last_name VARCHAR2(50) ) COMPRESS FOR OLTP;

27 Oracle SecureFiles High Performance Large Object Storage Substantial Performance Improvement Performance comparable to or greater than file systems Compression De-duplication Encryption Compatible with existing Oracle BLOB/CLOB syntax Compression and De-Duplication require Advanced Compression Option

28 Oracle SecureFiles Compression and De-Duplication CREATE TABLE images ( image_id NUMBER, image BLOB) LOB(image) STORE AS SECUREFILE ( TABLESPACE lob_tbs COMPRESS);

29 Oracle Partitioning Improve performance and manageability transparently Large Table Partition by Column Composite Partition Better query performance using partition elimination Partitioned data is easier to backup and recover Use lower cost storage for less used partitions

30 Oracle Partitioning Combining compression and partitioning Archival Compression DW Compression OLTP Compression Maximize performance of active data Increase compression and use lower cost storage for less used partitions

31 Flashback Flashback, Flashback Data Archive Time Current Data Undo Flashback: Query, Table, Tablespace, Transaction, Database Flashback available based on redo retention Flashback Data Archive provides infinite flashback and requires the Total Recall database option

32 Flashback Example Flashback query to a point in time select * from employees as of timestamp to_timestamp(' :30:00', 'yyyy-mm-dd hh:mi:ss') where name = :b1;

34 Real Application Clusters (RAC) Highly Available and Scalable Virtualizes low cost servers into a shared resource Scale Out to support more users Adapt to changes in workloads, fast connection failover

35 Oracle Data Guard Active Active High Availability Primary Database Active Stand-by Database Redo Transport Sync & Async Data Guard Broker Provide High Availability with failover to stand by databases Leverage your read only standby database for queries, reports, and testing on live data

36 Oracle Data Guard Reader Farms Production Database Reader Farm Queries Queries Updates Queries Real time synchronization
