This article mainly introduces the installation of Oracle 11g RAC and the creation and migration of 10g databases in the 11g RAC environment, and how to upgrade the database to the 11g version. The architecture of the 11g RAC and some new features of the 11g RAC are also analyzed and summarized. Oracle's 11g

Previously, we have set up the PAA environment for rac and data guard of a single instance database (see). To facilitate the switchover operation, we have configured data guard broker for the operation here! In the rac environment, you need to store the configuration file of data guard broker on shared storage! 1. modify the configuration file parameters of data guard broker to start the dmon process.

There are more processes on the RAC database than on a single instance database. These processes are unique to RAC and are set to implement cluster database functions. This article will introduce Rac-specific processes. 1. lmsn: Global cache service process. The lmsn Process maintains the data files in the Global Resource Directory (GRD) and the status of

Oracle RAC runs on top of the cluster, providing the highest levels of availability, scalability, and low-cost computing power for Oracle databases. If one node in the cluster fails, Oracle can continue to run on the remaining nodes. Oracle's main innovation is a technology called cache merging. Cache merging enables nodes in a cluster to efficiently synchronize their memory caches through high-speed cluster interconnection, thereby minimizing disk I/

security of the database, once lost, it is difficult to find back. Therefore, it is hoped that through the establishment of database clusters, the redundancy of the data set, the backup data to ensure security. Classification of database clusters Database cluster technology is a technology that combines multiple servers to form a cluster to achieve comprehensive performance better than a single large server, this technology can not only meet the need of application, but also save the investment

Previously, Oracle's Real Application Cluster (RAC) has always been promoted. We recommend that you use RAC for large database applications, because RAC also addresses the performance expansion and high reliability requirements of these customers. The other two competitors of Oracle, IBMDB2 and Microsoft SQL Server, only use Cluster to meet high reliability requi

Standby Database RAC is mainly a high-availability and scalable solution. One of its advantages is that it can protect the system from service loss when the instance fails, this causes unplanned interruptions in a single instance database. However, RAC generally does not prevent catastrophic site faults unless it is a long-distance cluster, which is rare during installation. Similarly, human errors may lea

the Oracle RAC database environment has a lot in common with a single-instance database environment, as well as many heterosexual. The same is true for updates to database patches, which can be done through Opatch. However, patch updates for the RAC environment are updated in several different ways, and even rolling upgrades can be implemented for all nodes in the case of a 0 outage. This article is mainly

different cluster products have their own characteristics, RAC features include the following points:• Dual-machine parallel. RAC is a parallel mode, not a traditional master and standby mode. That is, all members of the RAC cluster can receive client requests at the same time.• High availability. RAC is a high-availab
