I made a simple packaging class, the source code posted for your reference. This program is not rigorously tested and needs further refinement, and the code is tested through the xlc of Vs2005 and Aix. Note: If you need to link in vs2005, you will need to download the latest VS2005 Occi library files on the Oracle Web site. The following is a reference fragment: 　　TOcci.h #ifndef _occidatabase_h_ #define _occidatabase_h_ #include #include #include

released a commercial Oracle product on the PDP-11 computer that was available for Dec in the summer of 1979, which consolidates a more complete SQL implementation, including subqueries, joins, and other features. But it has to be said that the software is not very stable and lacks the important functions such as transaction processing. For market strategy, the company claims this is the second edition of

data files are stored in this shared store. There are some storage methods such as OCFS, OCFS2, RAW, NFS, ASM, and so on. The OCFS (Oracle Cluster file system) and OCFS2 are just a filesystem, and, like NFS, they provide a shared storage file system in a clustered environment. Raw bare devices are also a way of storage that is supported by RAC in previous versions of oracle11g, and before oralce9i, Ops/rac support can only be used in such a way that

access to a common shared database. Each instance has its own SGA, PGA, and background processes, which should be familiar because in a RAC configuration, each instance will need to be supported by these background processes. There are several ways to understand how RAC works and how it operates.(i) SCNThe SCN is a mechanism that Oracle uses to track the sequencing of changes within a database, and it can be imagined as a high-precision clock, with a

Oracle log performance and Principle Analysis, oracle log Introduction to Oracle log performance and Analysis of Its principles 1) Consistency and Performance Logs are a core component of all databases. It is related to database data consistency. Currently, we can see several databases Oracle, sqlserver, mysql, db2, a

The implementation of the program includes the operating system cluster, database cluster, hardware redundancy, network redundancy and so on. To do ha software, there are IBM's HACMP (many commonly used AIX people, often said Ha refers to hacmp, chaos), Sun Sun Cluster, HP Mc/sg and so on.Before 2000, we talk about Ha, most of the time is the operating system lev

Service, global memory services) and the Enquenceservice process management use the data Block synchronization interconnect between cluster nodes.Here are some questions to consider: The block is not read in all instances, and when the first instance reads, what is the lock, plus what lock? If there is another instance to read this block at this point, almost at the same time, then how can Oracle arbitrate, how to get one read, and the oth
