The following articles mainly describe the steps for restoring a database through DB2 backup and recovery.) I am a fan of DB2 databases. I am interested in understanding all the knowledge of DB2, although I was just familiar with the DB2 database, I sorted out the backup steps and shared them. Please correct me if something is wrong !!
1. Set archiving parameters
archive logs to 16. There will be no prompt for the next 17th and 18 th. Why? Let's take a look at the data file header and get the SCN of file 1.

587003 is better than next_change # (58681
I just got started with DB2, but I am not very familiar with the Backup recovery mechanism of DB2, and I am not familiar with the relevant information, so I have to explore it myself.
Requirement
Online compression and backup of the production database, which contains archived logs, regularly restores the backup of the

First, preface:When the database server is set up, the first thing we need to do is not to consider which MySQL-supported programs to run on this database server, but how to recover to the last normal state when the database is compromised, so that the loss of data is minimized.Or, the mere creation of a database server can only explain what it can do, and it does not mean that it can do something stably. The efficiency and comprehensiveness of disaster reco

There are two ways to back up SQL Server databases: one is to back up database files using
absence of backup, it is necessary to adopt unconventional means to restore the data.
1. Case application environment
Undo tablespace undo segments:

I will not talk nonsense. For more information about backup and recovery, refer to other blogs.
