networks (Sans) in one framework. The entire software system is connected to many open source applications such as Apache, Samba, LVM2, ext3, Linux NFS, and ISCSI Enterprise Target. Openfiler combines these ubiquitous technologies into an easy-to-manage, small management solution that is the front-end of a powerful WEB-based management interface.Openfiler supports CIFS, NFS, Http/dav, and FTP, but we will only use its ISCSI capabilities to achieve a low-cost SAN for shared storage components re

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

Oracle 11g R2 RAC: Configure DNS resolution scan vip Oracle 11gR2Grid Infrastructure (CRS) introduces Single Client Access Name (SCAN) to simplify Client Access to database services. This article will introduce in detail how to configure DNS to resolve scan vip demonstration environment OracleEnterprise Linux 5.6 I. In

public IP address cannot respond to the connection request. When a client session tries to connect to this faulty node, it must wait until the connection times out, which may be a long process. With the virtual IP address, it will be much faster: When a node fails, grid infrastructure failover the virtual IP address of the node to another node in the cluster. When a client session is connected to the virtual IP address of the faulty nodeInfrastructure knows that this node cannot work normally a

After Oracle 11g RAC is installed, why does crsd on the second node fail to start? The error message is CRS-4535: cannot communicate with cluster ready services. The specific error information must be viewed in the crsd. log. 1.

In general, Oracle 11g R2 RAC provides the following features: High Availability: shared-everything mode ensures that services are not stopped when a single node fails, and other nodes in the cluster will take over quickly Scalability: multiple nodes share the load and can provide processing capabilities far beyond that of a single database. Addition and dele

re-installed on the new nodes, patching is also simplified-only one Oracle Home Directory needs to be patched. However, patches cannot be installed in rolling mode, so the downtime is inevitable. During the installation process, Oracle universal installer will remind the Administrator to install or upgrade the database, or install only the software. If a new version is released during installation, it is b

I see a lot of questions on shared file systems the can used when people move from single instance to Oracle RAC Datab ASE and Grid Infrastructure. The most common question are the following: "should I place archive logs in OCFS2 or ASM or ACFS of 11g?" I ' ll try to clarify this topic below.First we need to understand a separation between

for many sites. ASM can be managed through Sql*plus, Enterprise Manager (Dbconsole), or DBCA. In Oracle 11g Release 2, ASM is now part of the grid infrastructure, whether in a single-instance or RAC environment. A new configuration Assistant ASMCA accepts and expands the functionality provided in the 11.1 dbca. ASM ca

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
