server OperationsThe Oracle database server relies heavily on the operating system running the server, and if the operating system does not provide the best performance, the Oracle database server will not be able to perform its due performance anyway.　　1.1.1 Planning syste

Oracle Database pioneered the design concept of tablespace, which makes an indelible contribution to the high performance of Oracle Database. In this case, many Oracle optimizations are implemented based on the tablespace design concept. Typical application 1: control the ta

The Oracle database server is the core of the entire system. Its performance directly affects the performance of the entire system. To adjust the performance of the Oracle database server, we mainly consider the following aspects: 1. Adjusting the operating system is suitable for the

physical design is to improve the performance of the system. The parameters of the whole physical design can be adjusted according to the actual operating conditions.Table and index data quantity estimation and physical storage parameters settingThe storage capacity estimates for tables and indexes are determined based on their record length and the maximum number of records estimated. The header cost of the data block and the header overhead of the

In Oracle, fields of the lob (large object, large object) type are increasingly used. This type of field has a large capacity (up to 4 GB of data), and a table can have multiple fields of this type, which is flexible, applicable to business areas with a large data volume (e.g., archives, etc ). However, although the storage capacity of fields such as long and lon
