RMAN :: Oracle Recovery Catalog Database In Primary And Standby Mode
Jul 9, 2013
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..?

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 am using RMAN with a recovery catalog option on a separate Database. My question is
When we use catalog does RMAN keep the information in Control file of the Target Database as well or only in recovery catalog? I am asking this in case We lost the database which contains the recovery catalog what to do?

we have a cluster of two nodes having oracle 11G R2 and another single instance server where RMAN is configured and this is backup server.i have created the service between the the target database and backup server and they are working fine i.e tnsping work fine at both sites.Now i have physical backup scripts written at one of cluster node and scripts run at crontab. The backup include full_backup , archive backup etc.
Now all physical backups work fine that is connecting RMAN and then catalog and then complete the backup but the full_backup do not connect catalog and throw this error that it do not know the SID in the connect descriptor. the tnsping output (from target ) is as followed fedb112 # tnsping bkp

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

Here we have a data guard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. Also we configured one schema on a third machine as catalog database using following steps. The steps executed in catalog database(appsdb):
SQL> create tablespace rmancatlog_tbs datafile '/u01/app/oracle/oradata/NEW/rman_catalog.dbf' size 500M autoextend off extent management local segment space management auto;
SQL> create user rman identified by oracle
2 default tablespace rmancatlog_tbs
3 quota unlimited on rmancatlog_tbs
4 ;SQL> GRANT connect, resource, recovery_catalog_owner TO rman;
RMAN> create catalog;
recovery catalog created
Added tns entries of catalog database in primary and standby. Then from primary database we tried to register to catalog database. It is showing that it is registering. But every query afterwards in rman is throwing the error. Below are the steps and error:

I want to remove matching dbid's from the rman catalog without compromising te integrity of the catalog. I do however know a single way of removing them and its using the dbid and db_key which in my case are not not unique. The funny thing is they've running normally for a year now.

What is the good practice to maintain RMAN catalog ?
RMAN backup and recovery is fine but to delete old backups it takes a lot of time.
Even if I delete backups manually,RMAN takes a lot of time to delete expired backup command.
What can be done to increase the speed of delete obsolete backup and delete expired backup operations ?

I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter. But I have not changed the protection mode(Maximum Performance). I would like to know whether there is any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY"?

i have done oracle data guard between two databases (database A is the primary) and (database B is the standby), and it was working fine for two weeks, then the network admin did some changes on the firewall on standby side, which made the primary database can not write on standby redo log , so archives was generated on primary and do not generated on standby by, now we solve the firewall probelm and new archives generated on primary is generated on atandby too, but now i have a gap in archives on standby database and standby database now is not synchronized with primary database, and data changes happen on primary is not reflected on standby, also archives that were generated on primary and did not generated on standby during the problem time is not registered in V$ARCHIVED_LOG neither on primary database nor on standby database

,I have a test environment with Primary DB Server, Physical Standby and Logical Standby.The Logical Standby DB (cur_log_stdb) is backed up every evening by RMAN and I have a question:If I recover my Logical Standby DB from backup and switch replication to new Logical Standby DB (new_log_stdb) it will work or not?My steps e.g.:1. Make a new server for my new_log_stdb and repair structure of catalogs;2. Repair listener.ora and tnsnames.ora files from cur_log_stdb to new_log_stdb;3.
Restore DB with RMAN from backup to new_log_stdb;4. On cur_log_stdb execute "alter database stop logical standby apply";5. Change a DNS name from cur_log_stdb to new_log_stdb;6. On new_log_stdb execute "alter database start logical standby apply immediate";I'm not sure that archivelogs will apply to the new_log_stdb for period since rman backup was created.
