The Company Introduct:
Kun-Peng is one of the companies which are specailized in data recovery in China. We are dedicate on Oracle database and disk array techonlogy research.
We are expert in the recovery of Raid disk array and all kinds of oracle database version recovery. Based on several year's research, we master the internal
structure of oracle database(8i,9i,10g,11g) and the algorithm of different kinds disk array. We develop the oracle database recovery tool "MYjDUL" and disk
array recovery tool "RaidDUL", which can recover the corrupted oracle datafile.
Our center are expert in the following aspects:
1. oracle database recovery, mainly including the follows:
(1) Recovery only with datafile after the system crashed, even there is no System tablespace and only have data tablespace. In short, we can recover only provided
(2) Recovery of the corrupted undo, system tablespace.
(3) Recovery from delete data, drop tablespace,drop, truncate table by mistake, both in non-archive log mode and archive log mode.
(4) Recovery the database which exists a lot of CLOB and BLOB data, and also repair all kinds of ORA- errors.
(5) Recovery the database which can't not import the DMP file.
(6) Recovery with the datafile having corrupted datablock.
(7) Recovery under the such circumstance: datafile is invalid, only have log file.
(8) Recovery that the datafile was deleted under Unix, Windows system by mistake.
(9) Recovery for the destory of oracle 10G, 11g ASM.
(10)recovery for the destory of oracle bigfile tablespace
(11)recovery for the destory of oracle compress table and tablespace
(12)recovery for the destory of oracle RAC ASM database
2. Disk Array data recovery:
We can recover data including IBM、DELL、HP、EMC, both hard RAID5 RAID0 & soft RAID5 RAID0 data recovery.We can also recover data without PCI IDE RAID Controller Card
and Disk Array Subsystem.
Our compnay has recoverd a lot of disk array including radi5 raid0 and other disk array and differnt brands of SAN NAS DAS for governments and enterprises. We have
successfully recovered the important data in the disk array of IBM SUN HP DELL EMC, with the OS system: Unix, window, Linux.We also recovered successfully for more than
one hundred RAID0 RAID1 RAID5 disk data array, the percentage of succesful recovery is more than 90%. Our company has advantage recovery techology in China.
1. Oracle 9.01, China Ericsson Company:
Tablespace met problem suddenly when it is resized, and the database can't startup; Kun-Peng has recoverd it successfully.
2. Oracle 9.06, Linux AS3, China Unicom branch company Company in Liao-ning Province:
The Oracle database has met problem on LINUX AS3 platform, with only 8 datafiles left, Kun-Peng has recovered 80% data.
3. Hospital system in He-Nan provice:
The Database server met problem with hardware, and can only provide RMAN backup, we successfully recovered its data.
4. ORACLE10R1, AIX, Real Estate Trading Center, Cheng-du
The DB server for Real Estate Trading Center, Chengdu was breakdown ,and only having a backup on HP tape device, however there are also problem with the tape backup.
Kun-Peng has successfully recovered its data.
5. ORACLE9201, HPUX, foreign-funded enterprise, Da-lian
One table was truncated by mistake, Kun-peng recovered the data under the cirsumtances that there does not exist any backup, and we recover the data only based on the data file.
6. ORACLE 816, HP-UX, State Administration of Taxation , Liao-yang:
The Oracle database 8.16 was run in the non-archivelog mode,and they met such error: ORA-01113: datafile 10 need meida recovery and ORA-01110: datafile 10 DBF error.
Kun-Peng recovered the database successfully ,even we didn't get latest backup.
7. ORACLE, Bank system , Jin-zhou:
The Oracle database can't startup due to "ora-01033: ORACLE initialization or shutdown in progress", and after check, we found that there are a lot of corrupted block in its datafile
and Kun-Peng recovered the data successfully.
8. oracle, AIX 5, Transportation Security Administration, Department of Communications of Liaoning Province:
The data has suddenly lost for all the Ben-xi distinct on the oracle system which run on Aix5, and it needs oracle recovery tablespace service. Kun-peng successfully recoverd the data 100%.
For the details, you can check the website of Department of Communications of Liaoning Province: http://www.lnyg.net/content/ViewContent.do?contentId=422
9. Raid 0-1 , hospital system, Guang-xi Province
Raid 0,1 hard disk was totally destroyed in a 4 harddisk disk array (The hard disk was opened by another company and exposed too long time.) However ,all the backup exists on that Raid, but
there are many copies of database backup files on that Raid. Kun-Peng ONLY used 3 hard diskes to recove morn than 90% data.
10. Oracle10G ASM, EMC, Hu-bei Electric Power Corporation
The oracle10G ASM was destroyed on the EMC storage. Part of the EMC storage was used to oracle ASM, and the other part was used for RMAN backupset as virtual tape. Since the storage crashed,
then the ORACLE database crashed, in which kepted a lot of engineering design drawings with LOB datatype. Kun-Peng recovered the data successfully.
11. Oracle 10G , Water Conservation Bureau, Nan-chang, Jiang-xi Province
The oracle database was destroyed in Oct, 2008. There is a RMAN backup on March, 2008. It was already restored the system01.dbf, but some of the archive-log was corrupted, so it can't be recoverd
to the destryed time. Kun-Peng recovered the data 100%.
