With the database, you can create table spaces. A tablespace (tablespace) is a logical division of a database, with at least one table space (called the system tablespace) for each database. To facilitate management and improve

Label:Oracle Basic ConceptsInstance An Oracle instance (Oracle Instance) consists of a series of background processes (Backguound Processes) and a memory structure (memories structures). There can be n instances of a database. User After the Oracle database is built, to build the table in the database, you must first establish the user for the database and specify the table space for the user.

Oracle Database space management skills Oracle Database space management skills The ORACLE tutorial is about space management of Oracle databases. In Oracle databases, DBAs can observe tables or views to understand the usage of the current space and make possible adjustments. I. Free Space for tablespace By observing the free space of a table space, you can determine whether the space allocated to a tablespace is too much or not. See the following statements It can be seen that only 0.19% o

It is used to store the SYSTEM's data dictionary tables, Program SYSTEM units, and process functions, packages and triggers can also be used to store user data tables and index objects.Tablespaces have the online and offline attributes.

In the ApplicationProgram. In this article, I will introduce two ideas: the first method is more complex, and the second method is simpler. Method 1: Old Rules This is a traditional method. If you use the getopenfilename or getsavefilename function, you can see the name. The former is used to open the file, and the latter is used to save the file. The usage of the two functions is the same. Therefore, I will show only one of them. No matter which function you use, a struct -- openfilename mus
