. Arecord is said to "own" another record if it represents it in the pagedirectory. Each entry in the page directory "owns" the records between Theprevious entry in the directory, up to and including itself . The Count Ofrecords "owned" by each record was stored in the record header, that Precedeseach record.The number of slots is specified in the first field of the Index header section of the page. Page directory includes at least Infimum and supremu

. Once an object is allocated from the heap, we need to know exactly who owns the object, because only the owner who owns the object can destroy it. But in the course of our actual use, this object may be passed to another object (for example by passing pointer arguments), and once the process is complex, it is difficult to determine who finally owns the object.

following is a brief introduction to these predetermined roles. The permissions that the role contains can be queried using the following statement:Sql>select * from Role_sys_privs where role= ' role name ';1. CONNECT, RESOURCE, DBAThese predefined roles are primarily for backwards compatibility. It is mainly used for database management. Oracle recommends that users design their own database management and security rights planning instead of simply using these predefined roles. In future relea

control handle has been created before you can call Invoke or BeginInvoke. Generally, only when in the constructor of the main form of the application When a background thread is created (as in Application. Run (new MainForm (), it is created before the form is displayed or Application. Run is canceled. This happens. One solution is to wait until the form handle has been created and then start the background thread. You can call the Handle attribute to forcibly create a Handle or wait for the L

installed as special users running CGI scripts. This is the user who owns the CGI program when the CGI program runs, and his permissions can limit what the script can do.In UNIX, the server itself runs as a root (system Super User or administrator, and allow it to use port 80 as the place for the browser to communicate with it (only root can use these "Reserved" ports 0 to 1023; all users can use the remaining ports ). When the server executes the CG

field (This field is incorrectly defined in winnt. H-it should be DWORD ratherHandle) contains the thread ID that owns this critical section. The difference between this field and the value (recursioncount-1) indicates how many other threads are waiting to obtain the critical section. Recursioncount This field contains the number of times that the owner thread has obtained the critical section. If the value is zero, the next thread that attempts to

Controlling companies Control Company Some companies are part owners of other companies because they have obtained a portion of the shares issued by other companies. For example, Ford owns 12% of Mazda's shares. It is said that if at least one of the following three conditions is met, Company A can control company B: Company A = Company B. Company A owns more than 50% of Company B's shares. Company A co

DebuginfoThis field contains a pointer pointing to the companion structure allocated by the system. The type of this field is rtl_critical_section_debug. This structure contains more valuable information and is also defined in winnt. h. We will conduct further research on it later. LockcountThis is the most important field in the critical section. It is initialized to a value of-1

counter: Retaincount. Method:-(NSUInteger) retainCount;//格式化方法：％ld The DEALLOC message is automatically sent to the object when the reserved counter of the object is returned to 0 o'clock. You can override the Dealloc method in your own object, which frees all related resources that have already been allocated, and you cannot call the Dealloc method directly. 9.12 Object Ownership When an entity owns an object, the entity is res

By defining a clear, cross-platform memory model that has been modified in JDK 5.0 to correct some of the errors in the original definition, it is possible to build a concurrency class "write once, run Anywhere", by following this simple rule: Whenever you write a variable that might be read by another thread, or if the variable you are reading is finally written by another thread,

this simple rule: Whenever you write a variable that might be read by another thread, or if the variable you are reading is finally written by another thread, you must synchronize. But now a little better, in the nearest JVM, there is no contention for synchronization (when a thread owns a lock, no other thread attempts to acquire the lock) the performance cost is still low.
