I have oracle 11g release 2.
 
 
My database is crash.I have only one datafile of billing.in which all important information is store.
 
 
I do not have dump.I have only one .dbf file.
 
Now i want to use this file when i create new database to regenerate data.
 
 
but how can i use that datafile?
 
As long as there is an intact datafile, there is hope :-)
 
But there is indeed no easy way to get your data back. As Aman suggested, contact Oracle Support immediately. 
Do not try to resolve this by yourself resp. by some clever advices from the internet!
Oracle Support has utilities like DUL to read your datafile without accessing it through an instance.
 

PRM-DUL is another alternative recovery unload  tool can be find here : http://www.parnassusdata.com/en/oracle-dul

rescue data oracle database

I am running two node RAC Oracle Database 11g, we had issue with shared storage - controller failure. After replacing the controller I see the ASM groups but the database is not starting due to errors. What is the best way to salvage the data ? I need some company that provides service to export several objects from one schema in the database. I believe that most of the database is unaffected by the controller failure, and I need to salvage the data from there.
Anyone has good experience with such company / service ?
 
 
What are the exact errors that you get ?
Do you have any backups for this database ?

Normally the best way "to salvage data" is simply to restore from backup. If you don't have any backup and have an Oracle Support contract you can ask Oracle Support for help: they have a tool named DUL for this kind of problems. See also http://www.oracle-internals.com/?p=17%20Blvd.

 
PRM-DUL can be another option : http://www.parnassusdata.com/en/oracle-dul

now I can not shutdown db, I can stop oracle db service and start it in windown services tool.
 
 
Answer:
 
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.

Salvage data from Oracle database with data dictionary corruptions

A database has experienced some damages - finally we have a running instance (with things like _allow_resetlogs_corruption=true).
We can only connect to the database as sys (works through network too). Connection as ordinary user doesn't work (results in ORA-01033)
Export doesn't work (since some data dictionary objects are not available)
Creating new objects, granting some privileges - doesn't work either
We can select data from some of the application tables (i.e. they have not been completely damaged)
We can't use some of the data dictionary views (e.g. dba_data_files, dba_segments fail). Others seem to work - e.g. dba_tables, dba_objects.
Seems database links to sys user doesn't work (so we can't easily connect to that database from another one)
 
My initial plan was to create db-link in another database and "create as select" for each table we want to salvage. However due to (6) we can't do that.
The number of affected tables is relatively large - dealing with each of them one by one is not feasible.
 
Any ideas for an easy way to save the data? What I'm thinking at the moment:
- Using some existing tool which connects to two databases and moves the data from the damaged database to the another one. (Should be able to connect to the damaged one as sysdba and not to rely on extensively querying objects' metadata since queries on data dictionary are very likely to fail)
- Writing own custom tool to do the tings in the previous point.
- Dumping data to external files (e.g. as insert statements; or other format): should be easy to automate bot the export and the import to the other database. (We don't want to spend many days to map flat file structures to tables).
- Finding some way to allow oracle creating database links to sys user (the it will be relatively easy to follow my initial plan).
 
Any suggestions? Recommendations for tools or other action plans?
 
 
Answer:
 
PRM-DUL can unload table data from failed database even  dictionary is corrupted .

One of my client had virus attack on his database server, in which the few of the database files got media corrupted.
I have downloaded you utility, and tried, but the utility takes lot of time and no display appears. 
Then I have run Dignosis script, and here with I am sending you the spool files.
 
Please guide me if this DB can be recovered and if yes then let me have commercials about the same.
 
 
 
For virus attack , we may need to use the non-dictionary mode. I wonder your database size,can you upload whole database all data files to us?
 
The virus is removed now.
Total database size is 46GB including system + undo +data
database file size of DATA is 12 GB + 8GB of Index 
 
 
 The system tablespace is damaged , so we have to use the non-dictionary mode,  we can extract the raw data as below , pls check if this is helpful.
 
Because of the data tablespace is not corrupted , so i think we can recover most of data.

question about oracle prm-dul license

Question:

 

I have downloaded the free version of your PRM-DUL tool and have gotten it working on an Oracle server that has some issues we hope to resolve.
 
We have been able to use the PRM-DUL tool to successfully access the database datafiles and access the system catalog and list of tables.
 
It appears that we are able to access data in the needed tables but we aren't able to determine how many total records per table are available - does the tool have a way to do this?
 
Is there a way to use a Where clause to retrieve only a portion of a table - like recent days - rather than trying to retrieve everything, especially if media errors impede access?
 
If the PRM-DUL tool can retrieve the data we need we will get a license for the tool.
 
We are trying to determine which PRM-DUL license we should get, how much it will cost, and how we make that payment and get the license key.
 
The PRM License Registration is provided on page 17 of the included manual and shows the following:
PRM License Registration
 
ParnassusData Recovery Manager (PRM) needs license for full use. ParnassusData provide the community version of PRM for user testing and demo. (Community version has no limits on ASM clone, and we will add more free features in it.)
 
It needs license for full use of PRM. Now, we provide two kinds of license for clients: Standard Edition and Enterprise Edition, and specifications are as follows.
 
 
Clients can purchase PRM license from official website: www.parnassusdata.com, and it needs Database name. After your purchasing, you will receive an email which includes a DBNAME and License Key.
 
Once you obtain the License Key, please register in the software as below,
 
1. In the Menu, Help => Register
 
2. Input DB NAME and you License Key, then click Register button
 
After registration, you don’t need to input license key again on your next boot. 
 
Looking at the website, I see no options to purchase the Standard license for $299, and the $999 Enterprise license is not available and is instead listed as $1500/per database.
 
Can you provide some pricing guidance 
 
  - is the $299 Standard license available?
 
  - is the price of the Enterprise license $999 or $1500?
 
 
 
Answer:
 
It appears that we are able to access data in the needed tables but we aren't able to determine how many total records per table are available - does the tool have a way to do this?
 
 
No, can not. But if you can ensure only some metadata is corrupted then of course ,the PRM-DUL can unload the whole table.
 
Is there a way to use a Where clause to retrieve only a portion of a table - like recent days - rather than trying to retrieve everything, especially if media errors impede access?


No,we can not. What prm do is like a FULL table scan or Full partition scan.
 
 
 - is the price of the Enterprise license $999 or $1500?
 
The current price is 1500 USD per license .

Help to recover database

We had the lost of our oracle database, and we couldn't recover using oracle recovery methods, we were trying your product but we couldn't recover nothing in a test environment, your tool doesn't work when we selected the datafiles and tried to recover.
 
Before buy the licence we need to Know if the database will be recover, we need some help to make the test and take the decision to buy the product.
 
I am going to explain the situation, the server where de database is suffering damage to the disk, then the tablespace system is corrupt and we can not read and we can not start up the database. Additionally the backup off the database was lost too and tho end our problem the export backup was damage too, in conclusion we only have the datafiles to recover data.
 
 
Answer:
 
At least prm can process your system datafile as picture:
 
prm.log show:
Error when process inserting data into prm_files or prm_work_mode:  Database './dbinfo/parnassus_dbinfo_DB_20170312094809' not found.
 
I think you may have no proper permission to write(PRM_HOME/dbinfo/parnassus_dbinfo_DB_20170312094809) this directory , can you pls try root user ?
 
Yes, we think prm can recover this case . And I will send you a payment link if you think it's ok to purchase .

oracle Data recovery Issue

October 24, 2018, 7:09 am
$
0
0
===SUMMARY OF THE ISSUE====
 
 
 
1. We lost data from few partitions and need  to restore and recover the data
 
 .The table is a Range partition and nearly we have lost 9 partitions.Each partition size is nearly 350GB( 9 partiions *350G=3TB)
 
2. The only backup available is from Jan 25 2015. This backup does not include SYSTEM tablespace backups.
 
3. We built a new environment and first restored datafiles from Jan 2015 backups.
 
4. Then used the most recent backup(Oct 2016) to restore SYSTEM tablespace to the new environment.Facing issues to open the database.
 
5. Data is available in the backup datafiles.Need to recover the data from datafiles.
 
 
 
I have gone through the  oracle PRM-DUL document and could not see any case study to recover the LOB data from the partitions,which were truncated.
We have to recover the data from few partitions(Lost 9 partitions) from Range partitioned table. 
Partitions contains the data "FILE_BLOB" BLOB, "FILE_XML" CLOB. Could you please provide the document which will explains to recover the LOB  data   from the partitioned table.
 
 prm can recover blob/clob from dropped partition in non-dictionary mode; first you use recovery wizard with non-dictionary mode , and scan the whole database /tablespace , and then you get your dropped partition listed by data object id ; select the dropped partition object in object tree, specify every column with right data type, and then you can use data bridge to recover your data. 
 
 pls let me know if you still have problem, actually this procedure is similar to recover from dropped table, but you have to specify  every column's data type, especially the lob column .
