There is a second issue that renders the connection pool ineffective, which is load related. In a heavily utilized environment new connections are handed out even though there are free connections available.
A portion of this can be explained by "free" connections that are actually enlisted in a transaction, thus these connections can *only* be handed out to a client participating in the same transaction. However, my extensive work with resolving Oracle session leaks has shown that multiple connections are enlisted in a single transaction - as the test code is written this should *never* happen. I have discussed this with Microsoft Support and they agree that this is most likely due to a "race condition" - the connection pooling manager does not mark the released connection available fast enough.
This results in the thread responsible for locating an available connection creating a new connection, as none are yet available.

One word often strikes fear in the hearts of working actors everywhere, and that word is "typecasting." Although the actual practice of typecasting is not necessarily sinister, its effect on an actor's career can be chilling. Essentially, typecasting is the practice of hiring an actor based primarily on a specific or infamous role he or she portrayed earlier. Typecasting can provide certain character actors with steady work, but it can also prevent others from being considered for more challenging roles.

One early example of typecasting involved the late actor George Reeves. Reeves had come to Hollywood in the 1930s to pursue leading man roles under the studio system, but only experienced moderate success. His strong physique and all-American demeanor made Reeves an ideal candidate for the role of Superman on the new medium of television, however. Reeve's portrayal of Superman made him famous, but when the series ended his hopes of reviving his movie career faded along with it. Reeves was offered roles which were simply variations of his successful Superman character. This form of typecasting also affected a number of other early television stars.

Typecasting also had a profound effect on actors such as Leonard Nimoy, whose portrayal of Spock on the original Star Trek television series made it difficult for him to find other film work in Hollywood. When actor Henry Winkler created the role of Arthur "Fonzie" Fonzarelli on the television series "Happy Days", one of his greatest personal fears was typecasting. Winkler, and other character actors in equally popular roles, have all had to step out of the public spotlight in order to avoid typecasting. Winkler had to prove that he could play other characters who were clearly not variations on Fonzie.

Some in the entertainment community make a distinction between casting for a specific type and typecasting. There's a reason why the same character actors portray the same roles in a number of movies and television shows. Casting according to type is a form of dramatic shorthand for the audience. The tough-talking New York cab driver or the wise old man are often used as stock characters in scripts, which means the same experienced character actors are usually cast. Typecasting usually involves a mainstream actor whose potential may be limited if he or she becomes too closely associated with a role.

Sometimes actors do break free of typecasting, but it often requires taking on an edgier dramatic role or a complete departure from type. Henry Winkler found some success by portraying unsympathetic characters, such as a serial rapist. By demonstrating a wide range of acting skills and a willingness to work against type, some actors are able to avoid the pitfalls of typecasting. Others are not as fortunate, portraying the same character type for the rest of their acting careers. Typecasting can be a double-edged sword, since the actor benefits from portraying a popular character, but often pays the price creatively after the role ends.

Converting an expression of a given type into another type is known as type- casting

If suppose object contains a value of integer type and you have to store this value in
primitive datatype called int( say, int i), then you have to typecast this value into int.

For ex, int i = (int)objVariable;

hi keona In computer science, type conversion or typecasting refers to changing an entity of one data type into another. This is done to take advantage of certain features of type hierarchies. For instance, values from a more limited set, such as integers, can be stored in a more compact format and later converted to a different format enabling operations not previously possible, such as division with several decimal places' worth of accuracy. In object-oriented programming languages, type conversion allows programs to treat objects of one type as one of their ancestor types to simplify interacting with them.

There are two types of conversion: implicit and explicit. The term for implicit type conversion is coercion. The most common form of explicit type conversion is known as casting. Explicit type conversion can also be achieved with separately defined conversion routines such as an overloaded object constructor.

Typecasting is the process by which a film, TV, or stage [actor] is strongly identified with a specific [character] , one or more particular [roles] , or characters with the same [traits] or [ethnic group] ing.
There have been instances in which an actor has been so strongly identified with a role as to make it impossible for him or her to find work playing other [characters] , as in the cases of [Adam West] , who played [Batman] , [Mark Hamill] , who played [Luke Skywalker] in the [Star Wars] movies and [William Shatner] , who played [Captain Kirk] in - although Shatner's highly-acclaimed performance in [Boston Legal] has by now undone most of the the Kirk typecast.

Some actors attempt to escape typecasting by choosing roles that are opposite the types of roles that they are known for; alternatively, a director may choose to cast an actor in a role that would be unusual for them to create a dramatic (or sometimes comedic) effect, such as [Liam Neeson] , who is usually casted in [mentor] -type roles, being cast as the [villain] [Ra's al Ghul] in [Batman Begins] . Typecasting also occurs in other [performing arts] . An [opera] singer who has a great deal of success in one role, such as [Denyce Graves] as [Carmen] , may become typecast in that role.
