TRY PRM-DUL here:
PRM can work on damaged file systems, ASM DiskGroup and data files. Even if Oracle data dictionary lost, PRM can also scan and recover dictionary based on inconsistent SYSTEM.DBF tablespace backup. PRM can support most of Oracle database functionalities for example, Cluster, LOB, and partition.
