Solving Performance Problems on Oracle DB
 
28:11
Solving Performance Problems on Oracle DB Matthew Vegh - Embarcadero Thursday, June 26, 2014 - 11am DBAs and database developers regularly spend a lot of time tracking down and resolving performance issues on the database servers they are responsible for; it can be very difficult, frustrating, and expensive. Given the complex interactions of applications, users and databases, new performance issues can arise almost as fast as old ones can be addressed. This session will simulate common performance problems on an Oracle server and then both identify those problems and provide effective solutions. Matthew Vegh is a Software Architect at Embarcadero Technologies for the Embarcadero DB Power Studio family of products and has been with the company for the better part of a decade. He has over 15 years of development experience with a wide range of technologies and a definite preference for database tooling.

02 Shared Lock & Exclusive Lock In oracle database table lock
 
11:32
Purpose Use the LOCK TABLE statement to lock one or more tables, table partitions, or table subpartitions in a specified mode. This lock manually overrides automatic locking and permits or denies access to a table or view by other users for the duration of your operation. Some forms of locks can be placed on the same table at the same time. Other locks allow only one lock for a table. A locked table remains locked until you either commit your transaction or roll it back, either entirely or to a savepoint before you locked the table. A lock never prevents other users from querying the table. A query never places a lock on a table. Readers never block writers and writers never block readers. See Also: Oracle Database Concepts for a complete description of the interaction of lock modes COMMIT ROLLBACK SAVEPOINT Prerequisites The table or view must be in your own schema or you must have the LOCK ANY TABLE system privilege, or you must have any object privilege on the table or view. ROW SHARE ROW SHARE permits concurrent access to the locked table but prohibits users from locking the entire table for exclusive access. ROW SHARE is synonymous with SHARE UPDATE, which is included for compatibility with earlier versions of Oracle Database. ROW EXCLUSIVE ROW EXCLUSIVE is the same as ROW SHARE, but it also prohibits locking in SHARE mode. ROW EXCLUSIVE locks are automatically obtained when updating, inserting, or deleting. SHARE UPDATE See ROW SHARE. SHARE SHARE permits concurrent queries but prohibits updates to the locked table. SHARE ROW EXCLUSIVE SHARE ROW EXCLUSIVE is used to look at a whole table and to allow others to look at rows in the table but to prohibit others from locking the table in SHARE mode or from updating rows. EXCLUSIVE EXCLUSIVE permits queries on the locked table but prohibits any other activity on it. NOWAIT Specify NOWAIT if you want the database to return control to you immediately if the specified table, partition, or table subpartition is already locked by another user. In this case, the database returns a message indicating that the table, partition, or subpartition is already locked by another user. WAIT Use the WAIT clause to indicate that the LOCK TABLE statement should wait up to the specified number of seconds to acquire a DML lock. There is no limit on the value of integer. If you specify neither NOWAIT nor WAIT, then the database waits indefinitely until the table is available, locks it, and returns control to you. When the database is executing DDL statements concurrently with DML statements, a timeout or deadlock can sometimes result. The database detects such timeouts and deadlocks and returns an error.

Oracle X$TRACE, Wait Event Internals and Background Process Communication
 
01:48:41
In this session we will look into some internals of Oracle background process communication and also some special types of wait events that most people aren’t aware of. We will use some exotic tracing for internals research and fun and some of this stuff is actually useful in real life too! I’m not going to reveal everything upfront, as this is a secret internals hacking session after all ;-) We will use various techniques to research what the “reliable message” wait event is about and how reliable background process communication is orchestrated in Oracle. This is a hacking session, not formal structured training, so I’ll just do free form demos and talk (probably no slides, just hacking stuff on the command line). Also, check out my full-week Advanced Oracle Troubleshooting online training at https://blog.tanelpoder.com/seminar

Oracle 11g Lock Monitoring with Read Committed Transaction Isolation Level Brief Explanation
 
12:24
Oracle 11g memiliki 2 jenis transaction isolation level yaitu Read Committed dan Serializable. Secara default transaction isolation pada Oracle adalah Read Committed, yaitu ketika sebuah session melakukan Insert/Update/Delete pada sebuah data dilanjutkan dengan commit maka session lain akan secara otomatis membaca data yang sama. Terdapat Row Level Lock (TX) dan Table Level Lock (TM). Video ini memberikan contoh jelas tentang transaksi yang terjadi ketika proses locking terjadi.

Simplified DBA-019-Data Concurrency and Locks
 
03:56
DATA CONCURRENCY More than one user connections ( session ) can access same data. For example user1 and user2 can view same employee information at the same time. But not two users can modify same data in one time. This is maintained by oracle lock mechanism. Before the database allows a session to modify data, the session must first lock the data that is being modified. A lock gives the session exclusive control over the data so that no other transaction can modify the locked data until the lock is released. Transactions can lock individual rows of data, multiple rows, or even entire tables. Oracle Database supports both manual and automatic locking. Automatically acquired locks always choose the lowest possible level of locking to minimize potential conflicts with other transactions. Demo: User1 is modifying an employee. User1 session will acquire a lock on the row. Same time user2 is trying to modify same employee. Since User1 has acquired lock, user2 has to wait until user1 releases the lock. Manual locking is possible. A user can place a lock manually as follows: LOCK TABLE mytable1 IN EXCLUSIVE MODE; With the preceding statement, any other transaction that tries to update a row in the locked table must wait until the transaction that issued the lock request completes. EXCLUSIVE is the strictest lock mode. The following are the other lock modes: ROW SHARE: Permits concurrent access to the locked table but prohibits sessions from locking the entire table for exclusive access ROW EXCLUSIVE: Is the same as ROW SHARE, but also prohibits locking in SHARE mode. The ROW EXCLUSIVE locks are automatically obtained when updating, inserting, or deleting data. ROW EXCLUSIVE locks allow multiple readers and one writer. SHARE: Permits concurrent queries but prohibits updates to the locked table. A SHARE lock is required (and automatically requested) to create an index on a table. However, online index creation requires a ROW SHARE lock that is used when building the index.
