are used for private SQL areas. UGA memory depends on the settings of the session. In dedicated service mode, sessions and processes are one-to-one relationships, and UGA is located in the PGA. The fixed UGA is a segment of memory in the PGA, and the UGA Heap is the PGA's sub heap. In MTS mode, the fixed UGA is a segment of memory in the shared pool, and the UGA Heap is a child heap of the large pool, which is allocated from the shared pool if the allocation fails from the large pool. In MTS m

1. Concept PGA: The program global area, the memory area used by the server process, including data and control information for a particular server process, such as private information and operating system resources used. UGA: The user global area, the memory area used by a specific session, such as the SQL workspace for the session, login authentication information, and so on. The impact of the session's SQL workspace size on query performance is critical, and UGA is allocated from the large

Sutherland-hodgman Polygon Clipping algorithm of CGA clipping algorithmThe Sutherland-hodgman algorithm is also called edge trimming, and the algorithm is Sasserande (i. E. Sutherland) and Trautman (Hodgman) were introduced in 1974.This algorithm adopts the method of segmentation processing and Edge cutting . This algorithm is suitable for the clipping of any convex or concave, or planar or non-planar polygon in any convex polygon window. 　　Edge-by-si

Seed filling algorithm of CGA filling algorithmThe plane area filling algorithm is an important algorithm in the field of computer graphics, which gives the boundary of an area (or the absence of a boundary, but only the specified color), which requires that all the pixel elements within the boundary range be modified to the specified color (or it may be a hatch). The most common area fill is polygon fills, this article discusses the seed fill algorit

Simply put, the purpose of the website standard is to: Provide the most benefits to the most users of the site to ensure that any Web site can effectively simplify the code for a

When you first started learning Web standards, there was this one: Encode all Any less than (), which is not part of the label, must be encoded as & G T;Any number (&), which is not part of the entity, must be encoded as & a M p;Note: There are no spaces between the above characters. This is often the case in our usual jobs: More >> Domestic counterparts are mostly to write two greater than >> or simply write >> (more exaggerated is some

manufacturers and models are in different formats, it makes information resources between different devices difficult to use each other, and the implementation of hospital PACS is very difficult. Medical Information systems bring about many new problems: how to store images with a large amount of data and effectively manage them? Can devices of different manufacturers be connected directly? How can information resources be shared between devices of different manufacturers? And so on. Obviously,

Well-designed the database, the two layers are basically finished, finding an intern and putting their positions on the tab is complete. Now, my team can put all its energy into the business layer. The business layer is the hardest hit by standardization. Here I decided to put a fierce person to solve this problem. Post: My database naming method is on
