In the real world, I believe many of my friends have encountered database or file system damages, and suddenly precious data cannot be accessed, which is too fatal for companies that use data as the foundation. In most scenarios, standard RMAN-based recovery procedures can solve such problems.

In a few scenarios, conventional recovery methods may fail, often due to backup unavailability, archive loss, or hardware damage, in this scenario, a pile of inconsistent data files and unusable databases are eventually left behind. However, many people do not realize that the contents of the database or file system are not completely cleared. They may not be able to open the database, but the vast majority of data is still intact. PRM is a tool that can directly read the intact data in the data file without running the Oracle Instance database Instance. As long as the data is not completely cleared or damaged, so PRM still has the hope of saving data.

PRM can work based on corrupted file systems, ASM Diskgroup, and data files. If the Oracle Data Dictionary is available, it will use Dictionary to make recovery easier, even if the dictionary comes from an inconsistent SYSTEM. DBF system tablespace backup. For PRM, most Oracle features are supported, such as Cluster, LOB, and partition table.
