Comparison between Oracle dedicated server and Shared Server

When creating an Oracle database, you should see this option in the database creation assistant wizard, which is the connection mode of the database. In Oracle9i or 10g, we can see two connection modes: a dedicated server connection (dedicated server) and a shared server connection (Shared Server ). Next we will classify the differences between the two connection methods. Dedicated server mode means that each time you access Oracle, the listener of the Oracle server will get this access request

Comparison of Oracle shared connections and dedicated connections

In the dedicated connection mode, the server establishes a connection with the client for every client request to connect to the database server. This connection is used to process all requests of the client, until the user actively disconnects or the network is interrupted. When the connection is idle, the background process PMON tests the user's connection status at intervals. If the connection is disconnected, PMON cleans up the site and releases related resources. A dedicated connection is e

Oracle memory problems

Oracle memory problems In Oracle, the memory structure mainly includes two categories: SGA and PGA. SGA represents the system global zone, and PGA represents the program global zone. Oracle memory mainly stores the execution program code (PL/SQL, JAVA); Information about connected sessions, including all currently active and inactive sessions; required information when running the program; for example, quer

Oracle parsing process details

Oracle Parsing process (SQL Parsing Flow digoal) When a user sends an SQL statement to the oracle database, runs the anonymous statement, or runs the SQL statement deployed in the database, the database works according to a certain working mechanism to understand the working mechanism, it can help developers write efficient code or understand some running symptoms. This is provided by Oracle on its official website metalink. We can describe the SQL processing process as follows: Oracle SQL parsi

A Preliminary Study of Oracle's shared connections and dedicated connections

In the dedicated connection mode, the server establishes a connection with the client for every client request to connect to the database server. This connection is used to process all requests of the client, until the user actively disconnects or the network is interrupted. When the connection is idle, the background process pmon tests the user's connection status at intervals. If the connection is disconnected, pmon cleans up the site and releases related resources. A dedicated connection is e

integrity of the database. For example, a control file is used to identify data files and redo log files. A database requires at least one control file. Data File: The file that stores the data. Redo log file: contains the changes made to the database, so that data recovery can be enabled in case of a fault. A database requires at least two redo log files. Parameter file: defines the features of Oracle routines. For example, it contains parameters for adjusting the memory structure of SGA. Arch
