In the previous section, "Data Guard series (2)-Log Transfer", we introduced the DG Log Transport service, the log Application service is introduced in this section after the log is transferred from the main library to the standby repository, and the repository needs to apply logs to maintain synchronization with the main library. Redo application or SQL application? We know that there are two types of re

Data Guard provides two services:1) Redo transmission service: Transfers Redo logs of Primay to one or more Standby destinations.2) Redo Application Service: The Redo log transmitted from Primay on the Standby side.This article describes the Redo transmission service. 1. Use ARCn to transmit Redo logsBy default, ARCn is used to transmit redo logs. However, ARCn can be used only in the highest-performance mo

To configure transparent gateway for Sybase 1. Install Sybase client on the server where Oracle is located (or install Oracle and Sybase servers on the same server) to ensure that the Sybase database can be accessed; 2. Install the transparent gateway for Sybase option, which must be customized. Correctly select the Sybase installation directory; 3. Select a sid string to be assigned to the Sybase Database.

The FAL gap problem of Oracle Data Guard logs is found in the OracleData Guard environment. A standby database has a problem and needs to be redone. Because the previously configured environment is good, you only need to back up the full database of the master database to the slave database. However, after the

Data Guard offers two main services:1 Redo Transport Service: The Primay end of the redo log transmission to one or more standby destinations.2 Redo Application Service: The redo log which is transmitted from the Primay end is applied to the standby end.This article first discusses the redo transport services. 1, the use of ARCN transmission redo logBy default, the ARCN transport redo log, but only in the

The data guard provides the following three kinds of protection modes: 1 Maximum protection mode (Maximum Protection) "Maximum protection" here refers to the maximum protection of the data is not lost, that is, at least one standby and primary maintain real-time synchronization, but this is costly, that is, when a transaction is committed, not only to write to

Non-Data guard patch installation tutorials refer to the [Oracle] CPU/PSU patch installation detailed tutorial, where Data Guard requires primary and standby to be patched at the same time, so the steps are more complex and the main steps are as follows: 1. Stop log transfer

); insert INTO Employee (Id,name) Span class= "Hljs-keyword" >values (03, ' Rose '); You've noticed that some data needs to be enclosed in single quotes, such as the names of Tom, Jack, and Rose, because their data types are char type. In addition, Varchar,text,date,time,enum and other types of data also require single-quote decoration, while int,float,double

RAC, Data Gurad, Stream are three tools in the Oracle High-availability system, each of which can be used independently or in conjunction with each other. Their respective emphasis is different, the application scenario is also different. RAC its strength lies in solving single point of failure and load balancing, so the RAC scheme is often used in the core system of 7*24, but the

reserved. Most of these digital binaries are used by standard SQL as column names and/or table names (for example, GROUP). A few are retained because MySQL needs them and (currently) uses the YACC parser. Reserved words can be used as identifiers when they are caused.MySQL allows some of the keywords to be used as unrecognized identifiers, because many people have been using them before. Some examples are listed below: ACTION BIT DATE Enum NO TEXT Time TIMES

Oracle Data Guard from the macroscopic point of view, mainly provides the following two services: 1) Log transmission: The main library transmits the generated redo log to the standby library; 2 log application: The redo log, which is transferred from the main library, is used by the standby library. This article first describes the log Transport service, the

[Oracle] Data Guard series (3)-log application Redo application or SQL application? We know that there are two types of standby databases: Physical standby database and logical standby database. The log application of the physical standby database is called the Redo application, the log application of the logical standby database is called the SQL application. Th
