Install Oracle 10g + RAC in RedHat 5.5 The cost is relatively low, the technology is mature, and the function is powerful. This solution will become more and more favored by small and medium-sized enterprises. I.

connection is established, that is, this failover mode only senses node failure when the connection is initiated, and if the node is unresponsive, the next address in the address list is automatically attempted. Once the connection is established, the node fails to do the processing, from the client's performance is the session is disconnected, the user program must re-establish the connection. The way to enable this failover is to add the Failover=on entry in the client's Tnsnames.ora, which

database. In the continuous recovery mode, oracle will not apply the archived logs, but will only apply the archived logs that will come later.New tables, tablespaces, and datafiles can be applied to the standby database through Logs. However, new temporary tablespaces and rename datafile cannot be applied to the standby database.When the archive log gap occurs, you need to find the corresponding archive log and copy the archive log to the log_archiv

Practicing Oracle's RAC build process, the first step is to practice installing Oracle 10.2.0.1.0 on 4U4 first. Installing RAC directly is somewhat difficult. From a simple start. For the total RAC Step, refer to the RAC form of the teacher.1. Start VC, login vsphere 5.1,2.

. That is to say, this type of Failover detects node faults only when a connection is initiated. If the node does not respond, the next address in the address list is automatically attempted. Once the connection is established, the node will not be processed if it fails. The client shows that the session is disconnected and the user program must re-establish the connection. To enable this type of Failover, add the FAILOVER = ON entry to tnsnames. ora of the client. This parameter is ON by defaul

checkpoint, if some of the steps fail, Oracle will automatically clean up the old configuration, so that you can fail to install after the installation does not need to reinstall, but to correct the error after continuing configuration, similar to the meaning of "breakpoint continuation.".For example, the following is the process of performing root.sh when

can be fixed, you may need to re-build the DG or Apply the new Standby, and then switch back to the Primary role. Failover may cause data loss due to the fault type of the Primary site.There are many tools for Switchover and Failover. The most common tools are SQL Command, Data Guard Broker, and DB Grid Control. This article describes how to use SQL Command to perform Switchover operations. References: Important configuration parameters of

Note: This article is translated from Oracle Data Guard 11g Handbook Page 78–page 88 In terms of data Guard (later written as DG), we only focus on the following three types of parameters: 1. Parameters independent of database roles2. Parameters when the database role is primary3. Parameters when the database role is standby Although DG has a lot of configuration
