DBRECOVER for Oracle user guide 0.5
DBRECOVER for Oracle is an enterprise-level Oracle data disaster recovery software. It can directly extract and recover data from the data files (datafile) of Oracle 8i to 21c databases, without needing to execute SQL through Oracle database instances to retrieve data. DBRECOVER, developed based on Java, requires no additional installation, and can be used directly after download and unzipping.
DBRECOVER features an intuitive GUI interface for easy and convenient operation. Users don't need to learn an additional set of commands, nor do they need to understand the underlying principles of Oracle's data structure, as they can easily recover data in the database through the Recovery Wizard.
You might be wondering, isn't the traditional Oracle Recovery Manager (RMAN) backup recovery sufficient? Why do we need to choose DBRECOVER? Let me answer your doubts.
With the rapid growth of enterprise IT systems, data capacity is increasing geometrically. Oracle DBAs often face issues such as the existing disk storage system not having enough capacity to store full backups, and the average repair time required for tape-based data backups during data recovery far exceeds expectations.
"Backup is paramount for databases" is a maxim that all DBAs keep in mind. However, the real world is full of disparities: lack of data backup space in the company's database environment, storage devices that cannot be delivered in the short term, and even finding that backups are actually unavailable during the data recovery process, are all common scenarios.
To solve these common data recovery dilemmas in the real world, DBRECOVER software fully utilizes its understanding of Oracle database's internal data structure, core startup process, and other internal principles. It can handle situations where the database cannot be smoothly opened due to issues like loss of SYSTEM tablespace, misoperation of Oracle data dictionary tables, and inconsistency of data dictionary caused by power outages, even in completely backup-free situations. It can remedy human errors such as truncation, deletion, or dropping of business data tables, and calmly recover data.
Even non-DBA personnel who have only been exposed to Oracle databases for a few days can easily use DBRECOVER. This is due to DBRECOVER's simple installation and fully graphical human-computer interaction interface. The person implementing the recovery does not need professional database knowledge, does not need to learn any commands, and does not need to understand the underlying storage structure of the database. Just a few clicks of the mouse can calmly recover data. DBRECOVER breaks the limitation that only a few professionals can carry out database recovery tasks, greatly shortening the time from database failure to complete data recovery, and reducing the total cost of enterprise data recovery.
