I want to take backup of selected data from tables of a schema (as huge data, that is not used, causing slow query performance) I planned to create a seprate backup schema and tablespace to store the data from these tables. Then write procedures that can move the data to and fro among table of those schema. And create partitioned index on those backup tables.

Is there a way to restore the schema and its associated objects once it is dropped?
1. The flash back database feature is not ON in the database where schema was dropped.
2. The data files/ table space has not been dropped
3. There was no export taken for the schema.
I am trying to remap schema from dump file to new user but my import fails and giving me error.

One of the developer dropped 18 tables by mistake on USER@db schema. Developer asked whether I can restore those tables, but unfortunately they are not in the recycle bin. Developer is re-creating the table now though. But I am just curious whether we need to change these parameters (db_recycle_cache_size) in order support any similar requests in the future.

My scenario is use RMAN to restore and recover database to a new host.The structure of two hosts are same.
In Host A:
1. Take a full backup.
2. Import a schema which has 191 tables in order to generate archivelogs.
In Host B:
I put all the folders(backupset, autobackup, archivelog) to the same directory. But after recovered the database, i checked that schema just has 175 tables, the latest few tables are missing.
I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.
I have completed the following steps in the restore process.
1. Creating a pfile from spfile
2. Changing the the location of cdump, udump, bdump and the control files ( there are three )
3. Then creating a spfile from this pfile
I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.
After mounting the database in RMAN, tried to run the following.

I want to list the tables in a schema which contains a particular value or data.
View 2 Replies View RelatedI'm trying to export a relatively large database but it's a bit more complicated than that.For one schema I need a full export / import (data included).
For another 10 schemas I need them empty, with the exception of a table in some of them which needs to be exported / imported with all data inside.Is it possible to do this with datapump utility (impdp, expdp)?
Afterwards I will be running some scripts to populate the DB instance with critical data / metadata.

i have many user tables in my database and i want to truncate selected tables and how i can overcome this scenario.
i can truncate using truncate table <table_name> but they are 250 tables to truncate, so,i can't write truncate command for every table. if i want to truncate first i have to truncate parent table or child table and how i can find parent table and child table for given tables to truncatein my database.
I have facing the below problem while the executing the query,
SELECT tmp1. *

tmp1
LEFT OUTER JOIN tmp2 ON tmp1.NUM_MAIN_ID = tmp2.NUM_MAIN_ID;

Tmp1 is remote TABLE, for which i have given dblink
My tnslistner is not working that is why i am not able to login in my database. so i have planned to reinstall it and if possible get my database back from old files.

We are trying to restore a database on the different server using RAM incremental level 0 and 1 backups. We have weekly Incremental level 0 backups along with incremental backups on daily basis. During recovery of Incremental level 0 backup, RMAN is expecting/looking for Incremental Level 0 backup of prior week as well. Is this the usual process for RMAN to look for prior level 0 backup though we need to restore from the current level 0 backup and roll forward by a week with subsequent Level 1 backup.?
We intend to restore from the Level 0 of 1/16 and roll forward with daily incrementals till 1/22. RMAN is expecting level 0 backupsets from 1/9 backup as well and keep failing since those backups are not available. quick inputs since we are in middle of recovery and trying to resolve if this is even doable.
db can only be opened if all the datafile and controlfiles are synchronize.I wonder if db crash and we dont have any kind of backup. is there some way to synchronize the control file with the datafile?....any way.db is not idle either when crashes we can manage data lose.just want our database open

I am able to recover the .dbf files by using a recovery tool.
is it possible to use this .dbf files into new server and recover my data.
Yesterday my colleague noticed that, the complete data (1 year) got missed out from a table and the data is available only from last friday.
And then we restroed the data from the backup.
Now we have been asked to find out who has deleted or truncated the data? But in the database, audit is enabled only to log sys operations.
So is there any way to find who ran the delete or truncate command on this DCA_CLA_BATCH table on friday?
SQL> show parameter audit

audit_file_dest string /dborafiles/edcap/edcapd/adump

Replication happens across the servers to make sure that the data is the same (synchronized). If one of the server crashes and later recovers, does it need to repair the data to keep them in sync with the other servers?

I have problem on using "delete obsolete" in RMAN.
First, let describe my backup configuration.
1. Full backup every Monday (17-Oct, 10-Oct, 3-Oct, 26-Sep)
2. Incremental backup for other days
3. Enable autobackup of control file
4. Backup archive log every day
5. RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS
6. Execute "Delete obsolete" every day
7. control file is used instead of catalog
The results observed:
1. Backup of control files older than 30 days will be deleted
2. Backup of archive log files older than 30 days will be deleted.
3. Backup of datafiles older than ~14 days but before 30 days are also DELETED.
In my example, the backup of datafiles created at 26-Sep is deleted at 16-Oct.
I tried "restore database validate until time "sysdate-22"" at 17-Oct. And RMAN reported "datafile xx will be created automatically during restore operation". It seems that RMAN failed to do restoration up to 22 days ago. The retention policy I set seems not effective on datafile backups.
I checked view v$backup_set and the "Keep" is "No" and "Keep until" is empty.
The only thing I can think of, is the settings of "CONTROL_FILE_RECORD_KEEP_TIME". It is marked "7" in the Oracle, which is less than the retention. But I suppose this only causes the backup not deleted, but NOT be deleted earlier.
