oracle database patching strategy

It is a good strategy to use the Oracle Import Export Tool (Import/export) for porting between Oracle databases. Although it is possible to reconstruct the database structure using the reverse Engineering in the Sybase power designer, the more complex data import process can be used, but the job queues, snapshots, and

. As for the "poisonous Snake" released, whether IBM can immediately unified database Lake, Cao Kaibin Information deputy general Manager of the world, said: "Oracle in the domestic market to occupy the largest share, but customer satisfaction must be improved, business model to improve." Although IBM has brought the leading technology and product to Chinese users, the large-scale marketing has just begun.

Let's start with some of the scripts we use to back up and restore Oracle databases directly using commands Oracle Data Backup: Step 1 Back up the user data. 1. Connect the Linux terminal using the database administrator account under Linux system. 2. Execute the following statement to create the "Bak_dir" folder. The code is as follows Copy

-class data management with integrated Business Intelligence (BI) tools. The Microsoft SQL Server Database engine provides more secure and reliable storage capabilities for relational and structured data, enabling you to build and manage high-availability and high-performance data applications for your business.The difference between Oracle and SQL Server: 　　 First, openness1, SQL Server can only run on Win

1. Backup tools You can directly use the Operating System Utility copy and CP to perform backup operations. However, Oracle strongly recommends that you use recovery Manager (RMAN ). RMAN can back up data files, control files, archived logs, and server parameter files ). Backups can be written to disks or tapes. 2. concepts and terms 2.1 full backup and partial backup Whole backup is a backup of all data files, control files, and server parameter file

The following is a summary of the basic common commands for databases in Oracle, the need for friends can come to reference the next 1. Get database name and date createdSELECT name, created, Log_mode, open_mode from V$database; 2, the Oracle database computer host name,

/oradata/orcl/users01. DBF ' online; 4. Restore operations using incremental backups Oracle automatically determines whether an incremental backup strategy is in use when restoring data files, and automatically applies the required incremental backup sets as needed. In this case, there is no need to perform a different recovery operation. During a restore operation that uses an incremental backup, the RE

. Get the exact location of each redo log (member) file for Oracle Copy Code code as follows: SELECT * from V$logfile; 7, know the Oracle database backup and recovery strategy and the location of the archive Copy Code code as follows: Archive Log List 8. Know how

Label:First, why need data backup The main reasons for data loss: 1, media failure. 2, the user's error operation. 3, the server's complete collapse. 4, computer viruses. 5. Unforeseen factors. The fault types in Oracle are divided into the following 4 categories. 　　1. Statement failure: A logical failure to execute a SQL statement procedure can cause a statement failure. If a user writes an invalid SQL statement, a statement failure occurs.

1. Get database name and date createdSELECT name, created, Log_mode, open_mode from V$database; 2, the Oracle database computer host name, Oracle database instance name and Oracle

First, IntroductionUltra-large systems are characterized by: 1, the number of users are generally more than million, and some more than tens of millions of data, the database generally more than 1TB; 2, the system must provide real-time response functions, the system needs to operate without downtime, the system requires a high availability and scalability. In order to meet the above requirements, in addition to the need for superior performance of th

Since Oracle database backups are available in three ways, each with different recovery characteristics, you should integrate database and file system backups, integrate logical and physical backups. First, backup strategy 1. At the operating system level, with a large-capacity disk array, each

Sun has made some achievements in Project Fortress, and Oracle Database giants should make persistent efforts. 13.

this is not enough for a period of time to monitor the performance of the database, in order to solve this problem, in 10g also added a new view: V$active_session_history. This is Ash (active session history).Typically, the most recent 5-10 minute details are required in order to diagnose the state of the current database. However, because the activity information of the session is time and space-consuming
