02 Shared Lock & Exclusive Lock In oracle database table lock
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.

03 Dead Lock in oracle database
DML Locks DML locks or data locks guarantee the integrity of data being accessed concurrently by multiple users. DML locks help to prevent damage caused by interference from simultaneous conflicting DML or DDL operations. By default, DML statements acquire both table-level locks and row-level locks. The reference for each type of lock or lock mode is the abbreviation used in the Locks Monitor from Oracle Enterprise Manager (OEM). For example, OEM might display TM for any table lock within Oracle rather than show an indicator for the mode of table lock (RS or SRX). Row Locks (TX) Row-level locks serve a primary function to prevent multiple transactions from modifying the same row. Whenever a transaction needs to modify a row, a row lock is acquired by Oracle. There is no hard limit on the exact number of row locks held by a statement or transaction. Also, unlike other database platforms, Oracle will never escalate a lock from the row level to a coarser granular level. This row locking ability provides the DBA with the finest granular level of locking possible and, as such, provides the best possible data concurrency and performance for transactions. The mixing of multiple concurrency levels of control and row level locking means that users face contention for data only whenever the same rows are accessed at the same time. Furthermore, readers of data will never have to wait for writers of the same data rows. Writers of data are not required to wait for readers of these same data rows except in the case of when a SELECT... FOR UPDATE is used. Writers will only wait on other writers if they try to update the same rows at the same point in time. In a few special cases, readers of data may need to wait for writers of the same data. For example, concerning certain unique issues with pending transactions in distributed database environments with Oracle. Transactions will acquire exclusive row locks for individual rows that are using modified INSERT, UPDATE, and DELETE statements and also for the SELECT with the FOR UPDATE clause. Modified rows are always locked in exclusive mode with Oracle so that other transactions do not modify the row until the transaction which holds the lock issues a commit or is rolled back. In the event that the Oracle database transaction does fail to complete successfully due to an instance failure, then Oracle database block level recovery will make a row available before the entire transaction is recovered. The Oracle database provides the mechanism by which row locks acquire automatically for the DML statements mentioned above. Whenever a transaction obtains row locks for a row, it also acquires a table lock for the corresponding table. Table locks prevent conflicts with DDL operations that would cause an override of data changes in the current transaction. Table Locks (TM) What are table locks in Oracle? Table locks perform concurrency control for simultaneous DDL operations so that a table is not dropped in the middle of a DML operation, for example. When Oracle issues a DDL or DML statement on a table, a table lock is then acquired. As a rule, table locks do not affect concurrency of DML operations. Locks can be acquired at both the table and sub-partition level with partitioned tables in Oracle. A transaction acquires a table lock when a table is modified in the following DML statements: INSERT, UPDATE, DELETE, SELECT with the FOR UPDATE clause, and LOCK TABLE. These DML operations require table locks for two purposes: to reserve DML access to the table on behalf of a transaction and to prevent DDL operations that would conflict with the transaction. Any table lock prevents the acquisition of an exclusive DDL lock on the same table, and thereby prevents DDL operations that require such locks. For example, a table cannot be altered or dropped if an uncommitted transaction holds a table lock for it. A table lock can be held in any of several modes: row share (RS), row exclusive (RX), share (S), share row exclusive (SRX), and exclusive (X). The restrictiveness of a table lock's mode determines the modes in which other table locks on the same table can be obtained and held.

Calling All Cars: Invitation to Murder / Bank Bandits and Bullets / Burglar Charges Collect
The Los Angeles Police Department (LAPD) is the police department of the city of Los Angeles, California. The LAPD has been copiously fictionalized in numerous movies, novels and television shows throughout its history. The department has also been associated with a number of controversies, mainly concerned with racial animosity, police brutality and police corruption. The radio show Calling All Cars hired LAPD radio dispacher Jesse Rosenquist to be the voice of the dispatcher. Rosenquist was already famous because home radios could tune into early police radio frequencies. As the first police radio dispatcher presented to the public ear, his was the voice that actors went to when called upon for a radio dispatcher role. The iconic television series Dragnet, with LAPD Detective Joe Friday as the primary character, was the first major media representation of the department. Real LAPD operations inspired Jack Webb to create the series and close cooperation with department officers let him make it as realistic as possible, including authentic police equipment and sound recording on-site at the police station. Due to Dragnet's popularity, LAPD Chief Parker "became, after J. Edgar Hoover, the most well known and respected law enforcement official in the nation". In the 1960s, when the LAPD under Chief Thomas Reddin expanded its community relations division and began efforts to reach out to the African-American community, Dragnet followed suit with more emphasis on internal affairs and community policing than solving crimes, the show's previous mainstay. Several prominent representations of the LAPD and its officers in television and film include Adam-12, Blue Streak, Blue Thunder, Boomtown, The Closer, Colors, Crash, Columbo, Dark Blue, Die Hard, End of Watch, Heat, Hollywood Homicide, Hunter, Internal Affairs, Jackie Brown, L.A. Confidential, Lakeview Terrace, Law & Order: Los Angeles, Life, Numb3rs, The Shield, Southland, Speed, Street Kings, SWAT, Training Day and the Lethal Weapon, Rush Hour and Terminator film series. The LAPD is also featured in the video games Midnight Club II, Midnight Club: Los Angeles, L.A. Noire and Call of Juarez: The Cartel. The LAPD has also been the subject of numerous novels. Elizabeth Linington used the department as her backdrop in three different series written under three different names, perhaps the most popular being those novel featuring Det. Lt. Luis Mendoza, who was introduced in the Edgar-nominated Case Pending. Joseph Wambaugh, the son of a Pittsburgh policeman, spent fourteen years in the department, using his background to write novels with authentic fictional depictions of life in the LAPD. Wambaugh also created the Emmy-winning TV anthology series Police Story. Wambaugh was also a major influence on James Ellroy, who wrote several novels about the Department set during the 1940s and 1950s, the most famous of which are probably The Black Dahlia, fictionalizing the LAPD's most famous "cold case", and L.A. Confidential, which was made into a film of the same name. Both the novel and the film chronicled mass-murder and corruption inside and outside the force during the Parker era. Critic Roger Ebert indicates that the film's characters (from the 1950s) "represent the choices ahead for the LAPD": assisting Hollywood limelight, aggressive policing with relaxed ethics, and a "straight arrow" approach. http://en.wikipedia.org/wiki/LAPD
