It may happen everyday that database reports error or system tablespace damaged, or cannot be accessed. It is too risky for your enterprise IT system. Most of cases can be resolved by RMAN.

 

PRM (ParnassusData Recovery Manager) is developed by Java which can be run all kinds of JAVA supported platform, Including: AIX, AIX、Solaris、HPUX、Linux and Windows.

 

PRM is designed for Enterprise Database Recovery, which includes all Oracle DUL data recovery functionalities, and also easy-to-use GUI.

PRM For Oracle Database 3.1 GUI:

PRM almost can recovery Oracle database on all operating system, including:

 

Linux (RedHat, Centos, Oracle Linux, Suse)AIX, Solaris, HPUX, Windows 2003 Server/XP/2000/NT

PRM Support Oracle database which starts from 9i, 10g, 11g to 12c.

 

 

However, few cases are failed to recover from RMAN or Achieve lost. The only left is inconsistent data files that are not usable for Oracle database. Many DBAs did not realize that the data is still usable, but just cannot be read by Oracle instance. PRM is that kind of tool, which can read the data direct from disk or file system without Oracle Instance.

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.

Why PRM-DUL is necessary?

 

Isn't RMAN enough for ORACLE database recovery? Why developing PRM for Oracle recovery?

 

In modern growing IT systems, database size is growing geometrically. Oracle DBAs are facing the problem that disks are insufficient for full backup, and tape storages take much more time than usual expectation.

 

Truth been told, "Database, backup 1st" is the first lesson for DBAs, however that fact is : backup disk not sufficient, storage not on time, even the backup image does now work.

 

In order to solve the above problems, PD Recovery Manager integrates the algorithm in Oracle database data structure, boot process which can solve system table lost, data dictionary error, and storage corruption impaction. In addition, it can also recovery the data from Truncate/Delete mistake.

 

No matter you are a professional DBA or new fish in Oracle world, you can master this user-friendly tool immediately. PRM is easy to install and use. You don't need to have any Oracle deep knowledge or skill in scripts, but just click-by-click finishing all recovery process.

 

Comparing the traditional recovery tool like Oracle DUL that is an Oracle internal tool and only for Oracle employee usage. PRM can be use for any kind of IT professionals or geeks. It saves time, decreases the recovery failure, and cuts down the total cost of enterprise.

 

There are 2 modes for data recovery:

By traditional way, data has to be extract to text file and then insert to new DB by SQLLDR tools, which takes double time and occupies double storage size.

 

ParnassusData Recovery Manager integrates data bridge function, which can extract data from original source and insert into new destination without any inter-media. This is a truly time and storage saver.

 

Oracle ASM is becoming popular in enterprise database implementation, due to its advantage in high performance, cluster support, and easy administration. However, for many IT professionals, ASM is a black box. Once ASM occurs error in DiskGroup mounting, it means that all data is locked in ASM. In this circumstance, without PRM, only senor Oracle experts can fix ASM internal structure, which is also a problem for oracle normal user.

 

PRM now can support  two kinds of ASM data recovery:

 

Once Disk Group cannot MOUNT, PRM can read metadata, and extract ASM file from Disk Group

Once Disk Group cannot MOUNT, PRM can read ASM file and extract data, which supports data export, and data bridge 2 modes
