SQL SERVER PART-12: Oracle Linked Database Server
 
03:46
HOW TO CREATE LINKED SERVER AND HOW TO QUERY ORACLE DATABASE FROM SQL SERVER MANAGEMENT STUDIO. SQL server 2017 makes it easy to configure linked server. You can use open-query to get or manipulate data of linked server database. CONFIGURATION SUMMARY: PROVIDER : oracle provider for oledb. DATA SOURCE : It is usually a combination of oracle server IP: port number/t.n.s listener name. e.g. 192.168.1.10:5121/orcl OPEN QUERY : select * form openquery(linked_server_name, ' sql query statement ') Configure a linked server to enable the SQL Server Database Engine to execute commands against OLE DB data sources outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel. Linked servers offer the following advantages: • The ability to access data from outside of SQL Server. • The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise. • The ability to address diverse data sources similarly. An oracle linked server require OLE DB provider. An OLE DB provider is a DLL that manages and interacts with a specific data source. If your oracle database is not in same server then you have to install The Oracle Data Access Components (ODAC) for Windows consists of Oracle client side drivers. An OLE DB data source identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches. Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The row set request may be in the form of executing a query against the provider or opening a base table from the provider.

While interacting with Database, use of Transaction is a very helpful approach particularly when the DB interaction involves inserting/updating/fetching data on more than one table structure. A set of DB tasks grouped into a single execution unit is refferd as a Transaction unit. If all the tasks completed successfully then the transaction completes and if one of the tasks fail, then the transaction rolls back.

Developing new services in Java with Oracle Tuxedo 12c
 
07:29
With Oracle Tuxedo 12c, one can develop new Tuxedo services using Java programming language to extend existing C/C++/COBOL applications. Java services are deployed and coexist in the same container as C/C++/COBOL services, allowing one to manage and monitor applications written in different programming languages using same set of tools. Coexistence in the same container also optimizes transaction coordination across services written in different languages. Java services development is based on POJO programming model and uses JATMI based API. In addition, XA transactions and monitoring and management, equivalent to C/C++/COBOL services, are supported for Java services. For more information, see Tuxedo documentation at http://www.oracle.com/technetwork/middleware/tuxedo/overview/index.html.

Transactions and Concurrency Control Patterns by Vlad Mihalcea
 
45:29
Transactions and Concurrency Control are very of paramount importance when it comes to enterprise systems data integrity. However, this topic is very tough since you have to understand the inner workings of the database system, its concurrency control design choices (e.g. 2PL, MVCC), transaction isolation levels and locking schemes. In this presentation, I'm going to explain what data anomalies can happen depending on the transaction isolation level, with references to Oracle, SQL Server, PostgreSQL, and MySQL. I will also demonstrate that database transactions are not enough, especially for multi-request web flows. For this reason, I'm going to present multiple application-level transaction patterns based on both optimistic and pessimistic locking mechanisms.

Using HBase Coprocessors to Build a Distributed, Transactional RDBMS
 
01:36:17
John Leach Co-Founder and CTO of Splice Machine with 15+ years software development and machine learning experience will discuss how to use HBase co-processors to build an ANSI-99 SQL database with 1) parallelization of SQL execution plans, 2) ACID transactions with snapshot isolation and 3) consistent secondary indexing. Transactions are critical in traditional RDBMSs because they ensure reliable updates across multiple rows and tables. Most operational applications require transactions, but even analytics systems use transactions to reliably update secondary indexes after a record insert or update. In the Hadoop ecosystem, HBase is a key-value store with real-time updates, but it does not have multi-row, multi-table transactions, secondary indexes or a robust query language like SQL. Combining SQL with a full transactional model over HBase opens a whole new set of OLTP and OLAP use cases for Hadoop that was traditionally reserved for RDBMSs like MySQL or Oracle. However, a transactional HBase system has the advantage of scaling out with commodity servers, leading to a 5x-10x cost savings over traditional databases like MySQL or Oracle. HBase co-processors, introduced in release 0.92, provide a flexible and high-performance framework to extend HBase. In this talk, we show how we used HBase co-processors to support a full ANSI SQL RDBMS without modifying the core HBase source. We will discuss how endpoint transactions are used to serialize SQL execution plans over to regions so that computation is local to where the data is stored. Additionally, we will show how observer co-processors simultaneously support both transactions and secondary indexing. The talk will also discuss how Splice Machine extended the work of Google Percolator, Yahoo Labs’ OMID, and the University of Waterloo on distributed snapshot isolation for transactions. Lastly, performance benchmarks will be provided, including full TPC-C and TPC-H results that show how Hadoop/HBase can be a replacement of traditional RDBMS solutions.

What does DISTRIBUTED DATABASE mean? DISTRIBUTED DATABASE meaning - DISTRIBUTED DATABASE definition - DISTRIBUTED DATABASE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A distributed database is a database in which storage devices are not all attached to a common processing unit such as the CPU, and which is controlled by a distributed database management system (together sometimes called a distributed database system). It may be stored in multiple computers, located in the same physical location; or may be dispersed over a network of interconnected computers. Unlike parallel systems, in which the processors are tightly coupled and constitute a single database system, a distributed database system consists of loosely coupled sites that share no physical components. System administrators can distribute collections of data (e.g. in a database) across multiple physical locations. A distributed database can reside on network servers on the Internet, on corporate intranets or extranets, or on other company networks. Because they store data across multiple computers, distributed databases can improve performance at end-user worksites by allowing transactions to be processed on many machines, instead of being limited to one. Two processes ensure that the distributed databases remain up-to-date and current: replication and duplication. 1. Replication involves using specialized software that looks for changes in the distributive database. Once the changes have been identified, the replication process makes all the databases look the same. The replication process can be complex and time-consuming depending on the size and number of the distributed databases. This process can also require a lot of time and computer resources. 2. Duplication, on the other hand, has less complexity. It basically identifies one database as a master and then duplicates that database. The duplication process is normally done at a set time after hours. This is to ensure that each distributed location has the same data. In the duplication process, users may change only the master database. This ensures that local data will not be overwritten. Both replication and duplication can keep the data current in all distributive locations. Besides distributed database replication and fragmentation, there are many other distributed database design technologies. For example, local autonomy, synchronous and asynchronous distributed database technologies. These technologies' implementations can and do depend on the needs of the business and the sensitivity/confidentiality of the data stored in the database, and the price the business is willing to spend on ensuring data security, consistency and integrity. When discussing access to distributed databases, Microsoft favors the term distributed query, which it defines in protocol-specific manner as "ny SELECT, INSERT, UPDATE, or DELETE statement that references tables and rowsets from one or more external OLE DB data sources". Oracle provides a more language-centric view in which distributed queries and distributed transactions form part of distributed SQL. Today the distributed DBMS market is evolving dramatically, with new, innovative entrants and incumbents supporting the growing use of unstructured data and NoSQL DBMS engines, as well as XML databases and NewSQL databases. These databases are increasingly supporting distributed database architecture that provides high availability and fault tolerance through replication and scale out ability. Some examples are Aerospike, Cassandra, Clusterpoint, ClustrixDB, Couchbase, Druid (open-source data store), FoundationDB, NuoDB, Riak and OrientDB. The blockchain technology popularised by bitcoin is an implementation of a distributed database.

A JDBC Datasource for Failing Over and Replaying In-Flight Transactions
 
56:07
Application continuity in the face of planned and unplanned database outages is a business requirement. Upon a database outage, Java applications are confronted with four main issues: hang, errors, outcome of in-flight work, and resubmission of in-flight work. This session presents a new JDBC datasource that transparently captures database interactions and then, upon database instance failure, fails over connections and replays in-flight transactions. Just plain standard JDBC, no proprietary API. In most cases, the replay datasource can transparently fail over in-flight transactions. The presentation also discusses design considerations, configurations, and restrictions.

ACID Properties in DBMS | acid properties in dbms in hindi | DBMS GATE | DBMS lectures in Hindi #106
 
05:02
Welcome to series of gate lectures by well academy In this video i am going to discuss ACID Properties in DBMS and also States of Transaction. The ACID Properties discussed in this video are in Hindi Language Atomicity − This property states that a transaction must be treated as an atomic unit, that is, either all of its operations are executed or none. There must be no state in a database where a transaction is left partially completed. States should be defined either before the execution of the transaction or after the execution/abortion/failure of the transaction. Consistency − The database must remain in a consistent state after any transaction. No transaction should have any adverse effect on the data residing in the database. If the database was in a consistent state before the execution of a transaction, it must remain consistent after the execution of the transaction as well. Durability − The database should be durable enough to hold all its latest updates even if the system fails or restarts. If a transaction updates a chunk of data in a database and commits, then the database will hold the modified data. If a transaction commits but the system fails before the data could be written on to the disk, then that data will be updated once the system springs back into action. Isolation − In a database system where more than one transaction are being executed simultaneously and in parallel, the property of isolation states that all the transactions will be carried out and executed as if it is the only transaction in the system. No transaction will affect the existence of any other transaction.

Speedy transactions in multicore in-memory databases
 
27:50
Silo is a new in-memory database that achieves excellent performance and scalability on modern multicore machines. Silo was designed from the ground up to use system memory and caches efficiently. For instance, it avoids all centralized contention points, including that of centralized transaction ID assignment. Silo's key contribution is a commit protocol based on optimistic concurrency control that provides serializability while avoiding all shared-memory writes for records that were only read. Though this might seem to complicate the enforcement of a serial order, correct logging and recovery is provided by linking periodically-updated epochs with the commit protocol. Silo provides the same guarantees as any serializable database without unnecessary scalability bottlenecks or much additional latency. Silo achieves almost 700,000 transactions per second on a standard TPC-C workload mix on a 32-core machine, as well as near-linear scalability. Considered per core, this is several times higher than previously reported results. In the ACM Digital Library: http://dl.acm.org/citation.cfm?id=2522713

Oracle Sharding Overview
 
39:04
Product overview of Oracle Sharding 12.2 Linear Scalability, Fault Isolation and Geo-distribution Oracle Sharding is a scalability and availability feature that enables distribution and replication of data across a pool of Oracle databases that do not share hardware or software. Applications elastically scale (data, transactions and users) to any level, on any platform, simply by adding additional databases (shards) to the pool.

What is MICROSOFT TRANSACTION SERVER? What does MICROSOFT TRANSACTION SERVER mean? MICROSOFT TRANSACTION SERVER meaning - MICROSOFT TRANSACTION SERVER definition - MICROSOFT TRANSACTION SERVER 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 Microsoft Transaction Server (MTS) was software that provided services to Component Object Model (COM) software components, to make it easier to create large distributed applications. The major services provided by MTS were automated transaction management, instance management (or just-in-time activation) and role-based security. MTS is considered to be the first major software to implement aspect-oriented programming. MTS was first offered in the Windows NT 4.0 Option Pack. In Windows 2000, MTS was enhanced and better integrated with the operating system and COM, and was renamed COM+. COM+ added object pooling, loosely-coupled events and user-defined simple transactions (compensating resource managers) to the features of MTS. COM+ is still provided with Windows Server 2003 and Windows Server 2008, and the Microsoft .NET Framework provides a wrapper for COM+ in the EnterpriseServices namespace. The Windows Communication Foundation (WCF) provides a way of calling COM+ applications with web services. However, COM+ is based on COM, and Microsoft's strategic software architecture is now web services and .NET, not COM. There are pure .NET-based alternatives for many of the features provided by COM+, and in the long term it is likely COM+ will be phased out.

Part 21   Transactions in ADO NET
 
16:16
c# transaction operation c# transaction rollback on exception c# transaction try catch c# transaction using rollback In this video we will discuss how to implement Transactions in ADO.NET What is a Transaction A Transaction ensures that either all of the database operations succeed or all of them fail. This means the job is never half done, either all of it is done or nothing is done. Let's understand this with an example. When we click "Transfer $10 from Account A1 to Account A2" button, we should subtract 10 from A1 account and add 10 to A2 account. So there will be 2 database UPDATE statements. What do you think will happen if only the first update statement is executed successfully and not the second statement. $10 is deducted from the first account, but not added to the second account. This is definitely not desirable. Either both the statements should succeed or both of them should fail. If one succeeds and other fails we should also rollback the changes made by the first statement to maintain the integrity of the data. This can be achieved using transactions in ado.net. namespace Demo { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { GetAccountsData(); } } private void GetAccountsData() { string cs = ConfigurationManager.ConnectionStrings["CS"].ConnectionString; using (SqlConnection con = new SqlConnection(cs)) { SqlCommand cmd = new SqlCommand("Select * from Accounts", con); con.Open(); SqlDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { if (rdr["AccountNumber"].ToString() == "A1") { lblAccountNumber1.Text = "A1"; lblName1.Text = rdr["CustomerName"].ToString(); lblBalance1.Text = rdr["Balance"].ToString(); } else { lblAccountNumber2.Text = "A2"; lblName2.Text = rdr["CustomerName"].ToString(); lblBalance2.Text = rdr["Balance"].ToString(); } } } } protected void btnTransfer_Click(object sender, EventArgs e) { string cs = ConfigurationManager.ConnectionStrings["CS"].ConnectionString; using (SqlConnection con = new SqlConnection(cs)) { con.Open(); // Begin a transaction. The connection needs to be open before we begin a transaction SqlTransaction transaction = con.BeginTransaction(); try { // Associate the first update command with the transaction SqlCommand cmd = new SqlCommand("Update Accounts set Balance = Balance - 10 where AccountNumber = 'A1'", con, transaction); cmd.ExecuteNonQuery(); // Associate the second update command with the transaction cmd = new SqlCommand("Update Accounts set Balance = Balance + 10 where AccountNumber = 'A2'", con, transaction); cmd.ExecuteNonQuery(); // If all goes well commit the transaction transaction.Commit(); lblMessage.ForeColor = System.Drawing.Color.Green; lblMessage.Text = "Transaction committed"; } catch { // If anything goes wrong, rollback the transaction transaction.Rollback(); lblMessage.ForeColor = System.Drawing.Color.Red; lblMessage.Text = "Transaction rolled back"; } } GetAccountsData(); } } } Testing : Run the apllication and click the "Transfer $10 from Account A1 to Account A2" button. Notice that $10 is deducted from Account A1 and added to Account A2 and the transaction is committed.
