Analyze information on a table, index, or cluster; Establish auditing options; Add comments to the data dictionary; So Oracle Database DDL commands include the Grant and revoke privileges which is actually part of Data control Language in Microsoft SQL server. Syntax for grant and revoke in Oracle Database:
In computing, a futex (short for "fast userspace mutex") is a kernel system call that programmers can use to implement basic locking, or as a building block for higher-level locking abstractions such as semaphores and POSIX mutexes or condition variables. A futex consists of a kernel-space wait queue that is attached to an atomic integer in ...
The DROP statement is distinct from the DELETE and TRUNCATE statements, in that DELETE and TRUNCATE do not remove the table itself. For example, a DELETE statement might delete some (or all) data from a table while leaving the table itself in the database, whereas a DROP statement removes the entire table from the database.
Premature task termination: Mutexes may also provide deletion safety, where the task holding the mutex cannot be accidentally deleted. [citation needed] Termination deadlock: If a mutex-holding task terminates for any reason, the OS can release the mutex and signal waiting tasks of this condition.
One of the entries in this block is the thread-local storage table for that thread. [1] Each call of TlsAlloc returns a unique index into this table. Each thread can independently use TlsSetValue(index, value) and obtain the specified value via TlsGetValue(index), because these set and look up an entry in the thread's own table.
(Reuters) -ABC News has agreed to give $15 million to U.S. President-elect Donald Trump’s presidential library to settle a lawsuit over comments that anchor George Stephanopoulos made on air ...
A mutex is a locking mechanism that sometimes uses the same basic implementation as the binary semaphore. However, they differ in how they are used. While a binary semaphore may be colloquially referred to as a mutex, a true mutex has a more specific use-case and definition, in that only the task that locked the mutex is supposed to unlock it ...
