- Internal corruption in the database.
- Formatting and reinstalling.
- Failure of virtual servers containing databases.
Steps to recovering data from Oracle databases
Search & Extract – if the database file is inaccessible due to hardware issues the storage device is repaired. If the file is missing, deleted or truncated, the file system is adjusted to point to the correct data stream. If there are not any pointers remaining, the entire data area is searched to find and extract Oracle database data.
- Analyse & Report – The Kroll Ontrack proprietary Oracle toolset analyses the complex internal structures of the extracted .DBF (or .ORA) files and provide reports detailing the recoverable tables and the number of data rows.
- Recover – The table data is copied into a SQL_LDR script to be imported into a new Oracle database.
Recovering Data From Oracle Linux System
With its Ontrack Data Recovery repair and recovery tools for Linux file systems including EXT3, EXT4, XFS, Reiser, JFS and GFS, Kroll Ontrack is unique in its abilities to recover data from systems running Oracle Linux.
Some common causes of data loss in Oracle Linux file systems include:
- File system or data corruption
- LVM corruption
- Deleted or partially overwritten data
- RAID and storage/server hardware failures
Recovering Data From Oracle VM
Data loss on virtual environments often has a high impact on the user organisation, as multiple virtual machines are often affected by a single technical failure or human error. Virtualisation brings an extra layer of complexity to a host system and when data loss occurs, Kroll Ontrack has the tools to respond. Kroll Ontrack supports file formats including VHD, VDI and VMDK which can be used by Oracle VM VirtualBox.
Some common causes of data loss in Oracle VM environments include:
- Guest and host file system corruption.
- Deleted virtual machines and snapshots.
- Internal virtual disk corruption.
- RAID and other storage/server hardware failures.
- Deleted or corrupt files contained within the virtual disk.
