Table Compression Enhancement in Oracle Database 11g R2
 
05:00
Table Compression: Overview Oracle Database supports three methods of table compression: 1.Basic table compression 2.OLTP table compression Oracle Corporation recommends to compress all data to reduce storage costs. The Oracle database can use table compression to eliminate duplicate values in a data block. For tables with highly redundant data, compression saves disk space and reduces memory use in the database buffer cache. Table compression is transparent to database applications. The table_compression clause is valid only for heap-organized tables. The COMPRESS keyword enables table compression. The NOCOMPRESS keyword disables table compression. NOCOMPRESS is the default. With basic compression, the Oracle database compresses data at the time of performing bulk load using operations such as direct loads or CREATE TABLE AS SELECT. With COMPRESS FOR OLTP, the Oracle database compresses data during all DML operations on the table.

Getting Started with PL/SQL Table Functions: Pipelined Table Functions
 
14:49
Pipelined table functions are table functions in which rows are returned or "piped" back to the calling query before the function has completed, avoiding the blocking behavior of normal PL/SQL functions and reduce PGA consumption. This video is part of the Oracle Dev Gym class "Getting Started with Table Functions". You can watch it independent of the class, but then you miss out on the tutorials and quizzes!

Webinar: All About the Function Result Cache
 
01:08:47
Presented by Steven Feuerstein, Oracle Corporation The function result cache, added in Oracle Database 11g, offers developers a way to dramatically reduce the amount of time it takes to retrieve data requested repeatedly by database sessions (specifically, when the same rows of a table are fetched much more frequently than they are changed). This cache is stored in the SGA, shared across all sessions in the instance, and automatically purged of "dirty data" by the Oracle Database. Every application running on 11.1 or higher should be taking advantage of this feature. Best of all, there is minimal impact on your code to start using this feature.

In this video, we will discuss about reloading data into cache automatically when data in the underlying database table has changed. Please watch Part 131, before proceeding with this video. To load data automatically into cache, when cached data is removed, we need to define a callback method. This callback method will be invoked when the respective item is removed from cache. So, the code to reload and re-cache data can be written in this method. The callback method signature should match, with the signature of "CacheItemRemovedCallback" delegate. The call back method is defined below. public void CacheItemRemovedCallbackMethod(string key, object value, CacheItemRemovedReason reason) { string CS = ConfigurationManager.ConnectionStrings["DBConnectionString"].ConnectionString; SqlConnection con = new SqlConnection(CS); SqlDataAdapter da = new SqlDataAdapter("spGetProducts", con); da.SelectCommand.CommandType = CommandType.StoredProcedure; DataSet ds = new DataSet(); da.Fill(ds); CacheItemRemovedCallback onCacheItemRemoved = new CacheItemRemovedCallback(CacheItemRemovedCallbackMethod); SqlCacheDependency sqlDependency = new SqlCacheDependency("Sample", "tblProducts"); Cache.Insert("ProductsData", ds, sqlDependency, DateTime.Now.AddHours(24), Cache.NoSlidingExpiration, CacheItemPriority.Default, onCacheItemRemoved); } Now, create an instance of "CacheItemRemovedCallback" delegate, and to the contructor pass the name of the callback method, that should be executed automatically when, the cached item is removed. CacheItemRemovedCallback onCacheItemRemoved = new CacheItemRemovedCallback(CacheItemRemovedCallbackMethod); In Part 131, to cache data, we used cache object's, Insert() method that takes 3 parameters, as shown below. Cache.Insert("ProductsData", ds, sqlDependency); Instead, let's use the overloaded version that takes 7 parameters and pass "onCacheItemRemoved" as an argument for "CacheItemRemovedCallback" parameter. Cache.Insert("ProductsData", ds, sqlDependency, DateTime.Now.AddHours(24), Cache.NoSlidingExpiration, CacheItemPriority.Default, onCacheItemRemoved); That's it. We are done. Now, please run the application. When "Get Data" button is clicked for the first time, the data is loaded from database. Once the data is loaded into cache, we always get it from cache when we click "Get Data". Now, execute an update statement on the database table. Notice that, when we click "Get Data" button now, we still get data from cache, but notice that, the updated data is loaded.

What happens when a query is issued to SQL Server 2. How to check what is in SQL Server plan cache 3. Things to consider to promote query plan reusability What happens when a query is issued to SQL Server In SQl Server, every query requires a query plan before it is executed. When you run a query the first time, the query gets compiled and a query plan is generated. This query plan is then saved in sql server query plan cache. Next time when we run the same query, the cached query plan is reused. This means sql server does not have to create the plan again for that same query. So reusing a query plan can increase the performance. How long the query plan stays in the plan cache depends on how often the plan is reused besides other factors. The more often the plan is reused the longer it stays in the plan cache. How to check what is in SQL Server plan cache SELECT cp.usecounts, cp.cacheobjtype, cp.objtype, st.text, qp.query_plan FROM sys.dm_exec_cached_plans AS cp CROSS APPLY sys.dm_exec_sql_text(plan_handle) AS st CROSS APPLY sys.dm_exec_query_plan(plan_handle) AS qp ORDER BY cp.usecounts DESC As you can see we have sorted the result set by usecounts column in descending order, so we can see the most frequently reused query plans on the top. usecounts - Number of times the plan is reused objtype - Specifies the type of object text - Text of the SQL query query_plan - Query execution plan in XML format To remove all elements from the plan cache use the following command DBCC FREEPROCCACHE In older versions of SQL Server up to SQL Server 6.5 only stored procedure plans are cached. The query plans for Adhoc sql statements or dynamic sql statements are not cached, so they get compiled every time. With SQL Server 7, and later versions the query plans for Adhoc sql statements and dynamic sql statements are also cached. Things to consider to promote query plan reusability For example, when we execute the following query the first time. The query is compiled, a plan is created and put in the cache. Select * From Employees Where FirstName = 'Mark' When we execute the same query again, it looks up the plan cache, and if a plan is available, it reuses the existing plan instead of creating the plan again which can improve the performance of the query. However, one important thing to keep in mind is that, the cache lookup is by a hash value computed from the query text. If the query text changes even slightly, sql server will not be able to reuse the existing plan. For example, even if you include an extra space somewhere in the query or you change the case, the query text hash will not match, and sql server will not be able find the plan in cache and ends up compiling the query again and creating a new plan. Another example : If you want the same query to find an employee whose FirstName is Steve instead of Mark. You would issue the following query Select * From Employees Where FirstName = 'Steve' Even in this case, since the query text has changed the hash will not match, and sql server will not be able find the plan in cache and ends up compiling the query again and creating a new plan. This is why, it is very important to use parameterised queries for sql server to be able to reuse cached query plans. With parameterised queries, sql server will not treat parameter values as part of the query text. So when you change the parameters values, sql server can still reuse the cached query plan. The following query uses parameters. So even if you change parameter values, the same query plan is reused. Declare @FirstName nvarchar(50) Set @FirstName = 'Steve' Execute sp_executesql N'Select * from Employees where [email protected]', N'@FN nvarchar(50)', @FirstName One important thing to keep in mind is that, when you have dynamic sql in a stored procedure, the query plan for the stored procedure does not include the dynamic SQL. The block of dynamic SQL has a query plan of its own. Summary: Never ever concatenate user input values with strings to build dynamic sql statements. Always use parameterised queries which not only promotes cached query plans reuse but also prevent sql injection attacks.

Webinar: Ten (Other) Top Tips for Improving PL/SQL Performance
 
01:08:03
Bulk processing (FORALL and BULK COLLECT), along with the function result cache, are the "big ticket" items when it comes to performance optimization with PL/SQL. But there's still more we can do to tweak our code for even better response times for our users. This third webast in the series starts with the automatic compiler optimization, showcases the extraordinary speediness of PGA data manipulation (a.k.a., package variables), and demonstrates the effect of the simple NOCOPY hint. We finish up with an introduction to pipelined table functions and some thoughts on optimizing your algorithms.

Partner Webcast -- Introduction to Oracle Coherence - 21 May 2013
 
01:01:42
Oracle Coherence is an in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast and reliable access to frequently used data. Oracle Coherence was originally designed as being a cache, but it has evolved significantly from its caching roots. Coherence provides replicated and distributed (partitioned) data management and caching services on top of a reliable, highly scalable peer-to-peer clustering protocol. By automatically and dynamically partitioning data, Oracle Coherence ensures continuous data availability, even in the event of a server failure. Coherence has no single points of failure; it automatically and transparently fails over and redistributes its clustered data management services when a server becomes unavailable.
