RMAN> sql 'alter system archive log current noswitch';sql statement: alter system archive log current noswitch

We have production database and standby database in 11g.
Production db server is taking care by different team even I don't have any access of the production server and I am responsible only for standby server. As of now everything is working fine except database backup on standby server because standby server is not register in catalog.
How to register standby server in catalog for RMAN backup?

I use windows 2003 server, oracle 10.2.0.4.0.My question is related to maintaing a standby database
1. Do we need to take RMAN full backup of standby database on a regular basis? At the moment I dont take backups of standby database.
2. I have FRA on standby database. The archivelogs from primary go to FRA on standby. I delete my archivelogs as follows:
DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-3';
Though the archivelogs are delete there are still empty folders of archivelogs that are not deleted. How to get rid of them automatically.

I have One Production and one logical standby database . Due to tape problem we are unable to take backups of primary . And due to business , we cannot take back up on disk in hot period(Bank database ) .
If i take logical standby database backup(level 0 ) using RMAN , then will i be able to restore it on production dtbs (In case Production down) ? . Logical standby is in sync with primary .

I have failed to duplicate target db for standby from active db using spfile with the following errors:
RMAN-03009: failure of backup command on prim1 channel at 08/11/2010 05:25:09
ORA-19558: error de-allocating device
ORA-19557: device error, device type: DISK, device name:

The script has successfully created on standby db all controlfiles and also has copied 2 data files DATA01.DBF and DATA02.DBF into the correct location. Then the errors above kicked in and stopped the rman dup process.

We are running a 5Tb database backup which takes really a long time to backup and impacts the performance in general during the backup. We got a DataGaurd database in place which we want to utilize to run the RMAN backup on to avoid performance impacts and just use DG database for backup and DR purposes. My Question is if we run the backups on DataGaurd Database, How would a RMAN DG database backup would clear the archive logs from Primary production and from DataGaurd Database during the backup process?

The customer wants the RMAN recovery catalog database to be highly available so that none of the RMAN database backup jobs are impacted at the time of taking the database backups. There are are 200+ databases running on OEL, RHEL and Windows. So we planned to host the recovery catalog database on Oracle Active DataGuard 11.2.0.1 Enterprise Edition on RedHat EL 5.8 version on two physical servers.
The Primary Instance will be in one server in the Primary DC and the Standby Instance will be on another server in another DC. Also all the database datafiles are hosted in ASM Diskgroups on SAN (DATA, FRA, REDO, ARCH diskgroups). Are there any specific RPM/patch/OS user custom/specific settings or configurations needed..?

How one should know whether RMAN is using target database control file or using separate catalog database. Also what one should do if he dont have catalog users credentials.

I'm going to backup this un-maintained Oracle 11g server in my office. I'm being told it's never been backed up and extremely critical to our success so tomorrow I'll be performing my 1st backup of the database using RMAN. My question is if I connect to the Oracle 11g database and run the:
[oracle@db1 ~]$ rman target=/
Recovery Manager: Release 11.2.0.1.0 - Production on Mon Feb 13 13:18:05 2012
connected to target database: CQDB (DBID=1854033249)
RMAN> shutdown immediate
using target database control file instead of recovery catalog
database closed
database dismounted
Oracle instance shut down
BACKUP DATABASET FORMAT �/oracle/u01/app/oracle/backup/%d-%T-%s-%P�;
My question is the above sufficient for a safe full backup? We only have the one single target database called 'cqdb' which houses several schemas. Can you tell me if this is correct? I've shut the database down so it's in a cold state so I don't think I need to configure the FRA (Flash / Fast Recovery Area) but I honestly don't know. This is my 2nd time on a Oracle DBMS.
What about the 'archivelog' files? Do I back those up? Do I need them in case a recovery? Also what about the 'controlfile'? Do I need to back those up as well as the mentioned above?

I have done many duplication before in sinlge instance databases using a backup tool and rman catalog. At the moment i was trying to do a RAC database duplication and facing some issues. For this i was doing a testing on my 1-node RAC. Primary and duplicated database is on the same Host and oracle version is 10.2.0.3. I perfomed following steps:
1.Created a DUPL database using DBCA.
2.Created a pfile using spfile.
3.Dropped all the datafiles, controlfiles and redo log files.
4.Started the database in nomount using pfile.
5.Disable cluster related parameters in pfile.
6.Took a full backup of the MAIN database with archivelog on disk.
6.Duplicate the database and it is done successfully.
7.Shutdown the instance and enabled cluster parameters.
8.Start instance using SRVCTL fails with error CRS-0215: Could not start resource 'ora.DUPL.DUPL1.inst'
But if start the instance using sqlplus it comes up nicely. There is not much information in alert log files.

I would like to duplicate to the different server Oracle Database with RMAN. I've configured flash recovery area for Oracle Database.
My questions are:
Source Server ( target ) : ORACLE_SID : DB11G
AUXILIARY Server (duplicate ): ORACLE_SID : CLONE
1- if backup files (autobackup and backup set)/ Archived Logs are in a different path on the source host (not default FRA Path) then how can I use the DUPLICATE command? BTW, only the flashback logs are in the default location (/u01/app/oracle/fra/flashback). Path: /u01/app/oracle/oradata/DB11G/autobackup and /u01/app/oracle/oradata/DB11G/backupset.
2 - Do I have to add *_CONVERT parameters for different SID as shown below? e.g. : DB_FILE_NAME_CONVERT , LOG_FILE_NAME_CONVERT.
DB11G.__java_pool_size=4194304
DB11G.__large_pool_size=4194304
DB11G.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment
DB11G.__pga_aggregate_target=155189248

Oracle Database 11.2.0.3
OEL 5.7
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?
