DataGuard is increasingly becoming an important tool for disaster recovery and pressure-sharing in databases. As the legendary DBA, you have to go to the kitchen and get to the hall.

DataGuard how to transmit Redo to Standby DataGuard transfers redo to standby and then applies the redo on standby to ensure data consistency between the two.The lgwr process is used to transmit redo logs. In the lgwr transfer mode, the lgwr process itself does not actually send redo to standby, but derives an lns (local network server) from lgwr)Process to transmit redo information. The main advantage of t

Analyze and solve the problem that MRP cannot be started in DataGuard I have a dedicated uard environment on hand, because it has been useless for some days.

Detailed steps for building dataguard at ORACLE11G (all physical standby operations)Preface:DATAGUARD establishes a reference relationship by establishing a PRIMARY and STANDBY group. Once STANDBY is created, DATAGUARD passes the REDO of the PRIMARY database (PRIMARY) to the STANDBY database, then, apply REDO in STANDBY to synchronize databases.1. installation environmentProject ListPrimary LibraryStandby L

Description There are many ways to create dataguard, this article is divided into one of the ways, 10g/11g are applicable. This paper creates an Oracle 11g Dataguard physical repository through the Rman target Master library and the local auxiliary library through a local backup recovery data file. First, the environment introduction 1. Primary database envir

When talking about the Gap Processing Mechanism of dataguard, the measure most people can say is to set fal_server and fal_client. From 9i, Oracle provides two types of log gap detection and processing mechanisms. For gap processing, the fal _ * parameter is not required in some cases. 1. Automatic Gap Resolution2.

implementation level, sparse files mean fewer redo logs are generated. So what is the difference between the features of Temp files and common files in the DG Environment?
