How to Detect Soft Corruption in Oracle 12c Database
 
18:19
Detection of Soft Corruption in 12c: To use the scripts below replace : , ",# and $ by proper bracket Lets Create a tablespace and small table. SQL: create tablespace DEMO1 datafile '/u02/tstdb1/TSTDB1/datafile/demo01.dbf' size 50M SQL: create table objects tablespace DEMO1 as select * from dba_objects; SQL: alter table objects add constraint pk_obj primary key #object_id$; SQL: create index idx_obj_name on objects#object_name$ tablespace demo1; Backup tablespace. RMAN: backup tablespace DEMO1; We need to put the DB in archivelog first Rebuild index with NOLOGGING option to simulate soft corruption later. RMAN: alter index idx_obj_name rebuild nologging; Confirm that we have datafiles that require backup because they have been affected with NOLOGGING operation. RMAN: report unrecoverable; Simulate corruption. RMAN: alter database datafile 5 offline; RMAN: restore datafile 5; RMAN: recover datafile 5; RMAN: alter database datafile 5 online; Query table with corrupted index and notice error. SQL: select count#*$ from objects where object_name like 'A%'; Let’s perform validation of datafile to check block corruption. RMAN: backup validate check logical datafile 5; Notice that we have 457 blocks marked corrupt but v$database_block_corruption view is empty. SQL: select count#*$ from v$database_block_corruption; Let’s query v$nonlogged_block view. set lines 200 set pages 999 select file#, block#, blocks,object#,reason from v$nonlogged_block; Will RMAN detect that we have corrupted blocks? RMAN: backup datafile 5; RMAN backup won’t fail due to NOLOGGING corrupt blocks and our backup will contain soft corrupted blocks. Let’s Identify corrupt segments using v$nonlogged_block view. set lines 2000 set pages 9999 col owner for a20 col partition_name for a10 col segment_name for a20 SELECT e.owner, e.segment_type, e.segment_name, e.partition_name, c.file# , greatest#e.block_id, c.block#$ corr_start_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ - greatest#e.block_id, c.block#$ + 1 blocks_corrupted FROM dba_extents e, V$NONLOGGED_BLOCK c WHERE e.file_id = c.file# AND e.block_id "= c.block# + c.blocks - 1 AND e.block_id + e.blocks - 1 := c.block# UNION SELECT s.owner, s.segment_type, s.segment_name, s.partition_name, c.file# , header_block corr_start_block# , header_block corr_end_block# , 1 blocks_corrupted FROM dba_segments s, V$NONLOGGED_BLOCK c WHERE s.header_file = c.file# AND s.header_block between c.block# and c.block# + c.blocks - 1 UNION SELECT null owner, null segment_type, null segment_name, null partition_name, c.file# , greatest#f.block_id, c.block#$ corr_start_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ - greatest#f.block_id, c.block#$ + 1 blocks_corrupted FROM dba_free_space f, V$NONLOGGED_BLOCK c WHERE f.file_id = c.file# AND f.block_id "= c.block# + c.blocks - 1 AND f.block_id + f.blocks - 1 := c.block# order by file#, corr_start_block# / This is the best outcome to get if you notice corruption errors. All errors are related to index corruption so we could fix this problem rebuilding index. alter index idx_obj_name rebuild; Simply issuing "alter index rebuild" command won't work. We should mark index unusable to drop segment before rebuilding it or just rebuild index with online option. It is better choice to mark index unusable because you don't need additional space then, but I will simply rebuild index with online option and see what will happen. SQL: alter index idx_obj_name rebuild online; Index altered. SQL: select count#*$ from objects where object_name like 'A%'; No errors... but, let's validate datafile for corruption. RMAN: backup validate check logical datafile 5; Notice "Marked Corrupt" column. Hm... 457 like before. Don't worry, this is not new corruption. These are FREE blocks which will be reused and Oracle will automatically re-format those blocks. Query the v$nonlogged_block view again as given above. We could force re-formatting creating dummy table and inserting data to dummy table. Check Doc ID 336133.1. create table s # n number, c varchar2#4000$ $ nologging tablespace DEMO1; SQL: BEGIN FOR i IN 1..1000000 LOOP INSERT /*+ APPEND */ INTO sys.s select i, lpad#'REFORMAT',3092, 'R'$ from dual; commit ; END LOOP; END; / SQL: drop table sys.s purge; Notice that we don't have corrupted blocks any more. RMAN: backup validate check logical datafile 5;

Very Large Databases Lessons Learned
 
01:10:26
Whoever coined the term "one size fits all" was not a DBA. Very large databases (VLDBs) have different needs from their smaller counterparts, and the techniques for effectively managing them need to grow along with their contents. In this session, join Microsoft Certified Master Bob Pusateri as he shares lessons learned over years of maintaining databases over 20TB in size. This talk will include techniques for speeding up maintenance operations before they start running unacceptably long, methods for minimizing user impact while critical processes run, the awesome world of data compression, and new features in SQL Server 2014 and 2016 that can really make your life easier. You'll also see how generally-accepted best practices aren't always the best idea for VLDB environments, and how, when, and why deviating from them can be appropriate. Just because databases are huge doesn't mean they aren't manageable, attend this session and see for yourself!

SQL Server Performance Tuning  Controlling Parallelism
 
01:08:54
Parallelism seems like it should be one of those things that the query engine takes care of for us, but it does require some care and tending from time to time. The default server configurations are no longer adequate for controlling parallelism, and DBAs need to know how to tweak the settings to make it run optimally. When parallelism goes awry, it can cause severe performance problems. Sometimes only for a specific query, sometimes it can hurt performance server-wide. To add a little complexity to the mix, parallelism can also be controlled by query hints and Resource Governor. Understanding how these three options for setting the Max Degree of Parallelism interact and who wins when they conflict is critical in being able to understand how to control it. Robert is a SQL Server Certified Master, MVP, and experienced DBA, evangelist, speaker, writer, and trainer. He has worked with SQL Server for 15+ years. He recently worked for Outerwall, Idera Software, and Microsoft. He served as PM for the SQL Server Certified Master Program at Microsoft Learning, and as a production DBA at Microsoft. He currently works as a principal database architect at DB Best Technologies. Robert is co-founder and co-leader of the PASS Security Virtual Chapter.

What is DATABASE TUNING? What does DATABASE TUNING mean? DATABASE TUNING meaning - DATABASE TUNING definition - DATABASE TUNING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Database tuning describes a group of activities used to optimize and homogenize the performance of a database. It usually overlaps with query tuning, but refers to design of the database files, selection of the database management system (DBMS) application, and configuration of the database's environment (operating system, CPU, etc.). Database tuning aims to maximize use of system resources to perform work as efficiently and rapidly as possible. Most systems are designed to manage their use of system resources, but there is still much room to improve their efficiency by customizing their settings and configuration for the database and the DBMS. Hardware and software configuration of disk subsystems are examined: RAID levels and configuration, block and stripe size allocation, and the configuration of disks, controller cards, storage cabinets, and external storage systems such as SANs. Transaction logs and temporary spaces are heavy consumers of I/O, and affect performance for all users of the database. Placing them appropriately is crucial. Frequently joined tables and indexes are placed so that as they are requested from file storage, they can be retrieved in parallel from separate disks simultaneously. Frequently accessed tables and indexes are placed on separate disks to balance I/O and prevent read queuing. DBMS tuning refers to tuning of the DBMS and the configuration of the memory and processing resources of the computer running the DBMS. This is typically done through configuring the DBMS, but the resources involved are shared with the host system. Tuning the DBMS can involve setting the recovery interval (time needed to restore the state of data to a particular point in time), assigning parallelism (the breaking up of work from a single query into tasks assigned to different processing resources), and network protocols used to communicate with database consumers. Memory is allocated for data, execution plans, procedure cache, and work space. It is much faster to access data in memory than data on storage, so maintaining a sizable cache of data makes activities perform faster. The same consideration is given to work space. Caching execution plans and procedures means that they are reused instead of recompiled when needed. It is important to take as much memory as possible, while leaving enough for other processes and the OS to use without excessive paging of memory to storage. Processing resources are sometimes assigned to specific activities to improve concurrency. On a server with eight processors, six could be reserved for the DBMS to maximize available processing resources for the database. Database maintenance includes backups, column statistics updates, and defragmentation of data inside the database files. On a heavily used database, the transaction log grows rapidly. Transaction log entries must be removed from the log to make room for future entries. Frequent transaction log backups are smaller, so they interrupt database activity for shorter periods of time. DBMS use statistic histograms to find data in a range against a table or index. Statistics updates should be scheduled frequently and sample as much of the underlying data as possible. Accurate and updated statistics allow query engines to make good decisions about execution plans, as well as efficiently locate data. Defragmentation of table and index data increases efficiency in accessing data. The amount of fragmentation depends on the nature of the data, how it is changed over time, and the amount of free space in database pages to accept inserts of data without creating additional pages.

What Makes the Oracle Exadata DB Machine Special
 
03:19
What Makes the DB Machine Special A Database Machine consists of two sets of Linux* machines. There's one set of Linux machines that we call compute nodes, and these have masses of CPU, masses of RAM, and they run your database instances. There's a second set of Linux machines that have a vast amount of disk space. These are your storage tier, and it's the Exadata software that links the compute nodes to the cell nodes, the cell nodes of the storage machines. Now, you cannot install the Exadata software independently. It comes pre-installed on your DB machine. I think, with earlier releases, it was possible to license Exadata software independently and install it on your own box, but certainly with the current release, you cannot get it unless you buy a DB machine. Well, what does Exadata deliver? It delivers certain capabilities that you cannot get in any other environments, and these are the abilities that we'll be studying in the next few slides. The Smart Scan, that's the one that gets all the publicity. It's the ability to offload a large amount of the SQL processing from the database tier from the compute nodes to the storage tier to the cell nodes. You have a storage tier that is aware of the database and can take over some of the workload of executing your SQL.

Best Android Studio Tutorial on How to Connect Android with PHP, MySQL (PhpMyAdmin) XAMPP. Please subscribe https://youtube.com/oumsaokosal?sub_confirmation=1 To connect Android with MySQL Database, you cannot do it directly. You need a Web service as a medium. In this case, we can use PHP because in PHP you can have a single of code that easily converts database data into the JSON format. You can convert it to XML as well, but many prefers JSON due to its size and performance. Best Android Studio Tutorial - How to Connect Android with PHP, MySQL Check out my new video at https://www.youtube.com/watch?v=5v_1cqkFSuQ This is another updated video about Android Volley: https://www.youtube.com/watch?v=OaWm0jORpKs&list=PL0DVoqvV_Tdhv5SziqTgGTBBsg2Mu6XvF Download the lib at https://github.com/kosalgeek/generic_asynctask You can learn Android Volley at https://www.youtube.com/playlist?list=PL0DVoqvV_Tdhv5SziqTgGTBBsg2Mu6XvF Android recently changed its IDE from Eclipse-based Android Development Toolkit (ADT) to IntelliJ IDEA-based Android Studio. The big reason for that is Gradle. Gradle is a modern open source build automation system. It works better in many ways than Ant, which is used by Eclipse-based Android IDE. The change also affects some old APIs to deprecate. In this tutorial "How to Connect Android with PHP, MySQL", l uses the new IDE, Android Studio along with the new APIs. Moreover, I created my own library that simplified the way of how to connect Android with PHP and MySQL. Before this, you had to have a private class extends AsyncTask class all the time in order to connect to the Web. The AsyncTask class works as background thread. Since Android 3.0 API 11 (Honeycombs), you are allowed to use the main thread to do a long process, such as connecting to Web. I named the lib as GenAsync.jar (Generic AsyncTask) and you can download it at https://github.com/kosalgeek/generic_asynctask. My lib hides all the complexity and all you have to do to instantiate the PostResponseAsyncTask class and pass a POST data as a second argument of the constructor. You call the execute() method and provide the URL that you want to pass the data to. Finally, you can receive the data by processFinish() method. This course guides how to create a database and a table in MySQL and create PHP pages.

RailsConf 2017: ​Postgres at Any Scale​ by Will Leinweber
 
37:27
​Postgres at Any Scale​ by Will Leinweber This is a sponsored talk by Citus Data. Postgres has powerful datatypes and a general emphasis on correctness which makes it a great choice for apps small and medium. Growing to very large sizes has been challenging—until now! First you'll learn how to take advantage of all PG has to offer for small scales, especially when it comes to keeping data consistent. Next you'll learn techniques for keeping apps running well at medium scales. And finally you'll learn how to take advantage of the open-source Citus extension that makes PG a distributed db, when your app joins the big leagues.
