I. version count description
This issue is described in the MOS documentation. For details, refer to [ID296377.1].
All SQL statements in Oracle are implicitly sharable. When a user submits an SQL statement, RDBMS performs a hash operation on the SQL statement and then generates a hash value, compare the hash value with the existing SQL statement in the shared pool. If the hash value is the same, reuse the previous SQL statement cursor. If the hash value does not exist, perform hard parsing.

draft language, and he can verify and express a software in a simple way, the second is a verification measurement method. QA can use it to quickly determine the results of the module.For building DSL, you will have to design your model and then use it (run time phase). Microsoft will offer a complete suite for building DSL (you can try the beta now !), And will also offer some pre-defined dialects for usage in their tools. I see Microsoft DSL vision more as a "configuration language" building

. Different arm architectures lead to major differences. The Banana Pi will have more features on the arm V7 architecture and can be compatible with various applications on arm V6. 2" is also somewhat different in product size. Please note that the existing Raspberry Pi shell cannot be used on banana pies and must be re-customized. 3. In terms of hardware connections, banana pie and Raspberry Pi more different points, adding a lot of Raspberry Pi previously did not interface, this is more obvi

LRU represents the least recently Used, which refers to the least recently used buffer header list. The buffer header concatenated with the LRU list points to the available data blocks.
And Lruw said least recently Used write, also known as the Dirty list, that is, dirty data block linked list, LRUW string up are modified but have not yet written data file memory data block corresponding to the buffer header.
A buffer header is

Note:
Both parentcursor and child cursor are library cache objects with the same structure. This can be confirmed by dump library cache.
Let's take a look at a management structure diagram of library cache. These figures are found in DSI.
Oracle uses Hash buckets to store related objects, such as cursor. Therefore, Oracle puts cursor in a specific buckets, which is operated by Oracle algorithms. There are many objects in each bucke

There are many similarities between the projects and other recently developed projects, and the projects are relatively small, there is no need for many innovations.
