in my catalog database I see in Rc_datafile mismatch sizes - column bytes shows data different from the real sizes of files .
Does this view updated after copy of database into catalog ?
Before I begin, I want to clarify that I am newbie in the administration of data warehouse.I need to know how to calculate the sizes of the archive and redo on data warehouse DB, in order to make an initial sizing of the BD on disks level.
Is there a formula to calculate the size?
why total size for undotbs1 is different from the acutal data file size in Operating system.
select tablespace_name, sum(bytes/1024/1024) from dba_data_files
where tablespace_name like 'UNDO%'
group by tablespace_name;
tablespacename total size
UNDOTBS1 2000
UNDOTBS2 7284

In mean time I executed some query and it has changed the file no 55. so now my question whether rman will go and bacup this datafile(datafile no 55) again or it will leave this file as it is?

View 14 Replies View RelatedAs part of an incremental backup I recover copies of the tablespaces. These by default are stored in the disk backup location diskgroup. Is it possible to move these copies to another disk group / location whilst still backing up to the default disk backup location diskgroup. I know how to do it with the main datafiles but not with the copies.
e.g.
Current situation:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +FRA
New setup to be:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +BACKUP
I have one database which is fully restored from client backup (RMAN). Database was up and running perfectly. By mistake I have deleted one schema/user and its tablespace using drop command. I have RMAN backup so want to restore that schema's datafile from the backup but when I run below statement it throwing error :
run {
allocate channel c1 device type disk ;
set newname for datafile 45 to '/ora/oradata/JSIP1/data.dbf';
RESTORE datafile 45;
switch datafile 45;
recover datafile 45;
SQL ' alter database datafile 45 online ' ;
}
RMAN-20201: datafile 45 not found in recovery catalog
or If I go and try to restore the tablespace of that schemas using below block it throws error:
run {

RECOVER TABLESPACE DATA;
SQL 'ALTER TABLESPACE DATA ONLINE';
}
RMAN - 20202 Tablespace not found in the recovery catalog
RMAN -06019 could not transalate tablespace name "DATA"
how to restored drop users and tablespace data from the RMAN backup.
I am writing following query

I just want to display only those records from JLS_LIST_TYPE which is not present in other table JLS_LIST_CONTROL ... for this i wrote above query but it is not working.

Could we skip the backup of the above missing files using RMAN -> backup database skip inaccessible;On further research, this would compromise tablespace SYSAUX recoverability...Questions:
1) What caused the above missing files to get created?
2) What is recommended: Recover the datafiles?
Is there a way to alter an existing virtual column to set as a real column without dropping it and recreate (i have index on it, and i don't want to recreate them).
View 2 Replies View RelatedWe have a Oracle 10g database with RAC and Dataguard. When we look at the AWR report, the wait time shown by Oracle for this database is very high.
Service Time : 15.36%
Wait Time : 84.64%
This would imply Oracle is waiting for resources 85% of the time and only processing SQL queries during 15% of its non-idle time. However when we check the OS (RHEL), the iowait is only about 10% and the CPU is 80% idle. This means that that processing horsepower is available.
As such, the results between the OS and Oracle database (AWR report) seems contradictory. OS says we have CPU/IO capacity, however Oracle says we don't.
I am trying to load the data from .csv file into the table using SQL Loader.
The table has the following schema:
src_id : number,
dest_id : number,
range: intsys.interval_typ --- > a type containing (lower,upper)
payload : varchar2(100)
The loader.ctl file is :
load data
infile *
append
into table sb_packet
fields terminated by "," optionally enclosed by ' " '
(src_id,dest_id,range,payload)
BEGINDATA
3,32,intsys.interval_typ(10043,142703),"misc data"
When I use the following this ctl file to transfer the data, i get the following error:

I use the following script to duplicate a target to an auxiliary instance. This works fine once.
However if I run it a second time it will create a new set of datafiles leaving the original files in place taking up space.
Is there something that I can put in the script that will stop this happening.
I know I could probably put a "set newname for datafile" clause for each datafile in the target database, but this makes the script over complicated and I would like to keep it as generic as possible.

We have a host for restore purposes. We execute monthly or quarterly restore operations to verify that I am able to restore a subset of the data in the given amount of time or to other purposes. I have a automated script to Clone the Database, but to Clone Database we need remove the old database from ASM before start this operation. I want remove only Database files and keep the configuration (such as oratab/network/ocr and so on).
Question: There is a easy way to remove these files without connect on ASM or by using DBCA?
Accidentally without checking the channel allocation I have given the backup archivelog from sequence until sequence with delete input. This backup piece went to the disk but it should go to Tape.I know that we can catalog this backup piece but I want to move this backup files in disk to Tape using RMAN. Is there anyway or I have to lie with Backup team or OS team for this file movement?

View 4 Replies View RelatedI took backup of Datafiles , archivelog files and controlfile through RMAN. Now, i want 3 backup file will created as a output of RMAN operation. It would be :
1 backupfile for all the datafiles
1 backupfile for all the archivelog files
1 backupfile for controlfile.
It have to be regardlessly whatevr my DB size is. It it possible to do so. How i can can write rman script to accomplish the task.
I would like to know that if I enable backup Optimization on then incremental full backup skip any files which was earlier backup? Because we may know that backup Optimization on ensure skip those files which are already taken backup.
Database : oracle 10g 10.2.0.3 .
I have restored database with the name DB to another database called DB01
it is in STARTED status (not mounted) and it seems I can not change the name if it is not mounts, and I can not mount it because of the name, how to solve this issue if possible? I have RMAN full backup from DB on my current server which hosting the database DB01 the initdb01.ora is ready and configured with DB01
what can I do next
ORA-01103: database name 'DB' in control file is not 'DB01'
We have a nightly rman backup that was complete and clean.The backup contains a Data File, Control File and a backup Archive Log file.The database server crashed with all the subsequent archive logs lost.
We are trying to recover from the three backup files.We are bumping into the backup piece missing as all the archive logs are done. how to restore with the exising backup files. the lost archive logs are probably salvageable.

View 39 Replies View RelatedIn my Production DB. 5 Datafiles created in same tablespace. Datafile size is of 25GB. Data stored in all Datafile. Data is just 5GB in all datafile. I want to move data from 5 datafiles to single or couple of datafiles.

why can not we resize online redolog files instead of re-creating the same with large size and remove the older onces.2. How can we make RMAN obsolute backups as usable ?
View 8 Replies View Relatedwhat people have set for the SGA and PGA sizes for their larger usage, larger data, databases? I've been seeing one of our warehouses grow both in terms of tables (number and sizes) and users groups querying the database. We're at 96g sga and 10g pga, but was thinking in terms of 1/2 tB machine to pin some larger tables. I know we'll have SSD soon, but am seeing enourmous numbers of reports using windowing and analytic functions and in line sets being created. How big in general do you have your larger systems set to?
View 2 Replies View RelatedI did some google searches about large number of extents and ASSM. I see bits and pieces on the web. This is something I need to look at while testing an application. Not looking to go into 'why' I would use smaller extents, I just want to make sure I have what I need to look for during testing..Issues with massive numbers of extents:
1. DBA_EXTENTS query is really slow.
2. issues truncating tables (due to having to read lots of extents)
3. issues splitting maxvalue partitions and with dropping partitions.
4. if I stay away from ASSM, would this reduce these issues? Are there any other performance issues or other issues I need to know about to check when I do tests?
Any issues with query or insert wait time? The tables that would get smaller events would have thousands of partitions/sub-partitions . Most of these sub-partitions will be rather smaller.I just want to test for a variety of different cases. The 'why' will come out during testing.
