RMAN :: Clone 2 Node RAC Database To Single Instance Non-RAC Database Using Existing Backup
Jul 25, 2012
I tried to clone a 2 node rac database to single instance non rac database using existing backup. I have not used connectivity to target or catalog. rman duplicate finished with below messages:
rman auxiliary sys/******@dbracdup
RMAN> duplicate database to dbrac spfile backup location '/oracle/backup';
...
...
Finished recover at 25-JUL-12
Segmentation fault
And the database was in mount stage, and when i tried to open database it failed with below error:
SQL> alter database open;
alter database open

ERROR at line 1:
ORA-19838: Cannot use this control file to open database .
I have an issue with restoring a RMAN backup that i have with me to a new database instance. What i have with me are: 1. Backup of SPFile.
(O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_.BKP)2. Backup of Control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_.BKP)3. Full database backup (O1_MF_NNSNF_FULLPROD_BU_92DVGW9H_.BKP)
I have received these files from a customer environment and I need to restore these to a new database instance in a local machine. I have given a attempt as follows (in Oracle 10g): 1, Created a new database instance (Test75) using Oracle Database Configuration Assistant2. SET ORACLE_SID = Test753. Connected to this instance using RMAN4. Tried to restore the SPFILE from the received BKP file.I am getting errors and cannot proceed. I am not sure whether I am executing the correct steps.
We have oracle database 10g(10.2.0.4) running on AIX 5.1. we have installed 2-node RAC on another server AIX 6.1 . Now we want to migrate our single node database to new 2-node rac environment. how we can move/migrate/cluster-aware our single node database to 2-node rac?
I'd like to confirm whether its possible to clone a database instance from a RAC cluster to a single server, with an additional issue that the RAC cluster is running Oracle 10g and the single server is running 11g. Can I do that directly or do I need an intermediate step to upgrade the database instace to 11g? Or can I even use exp/imp on RAC?
We have an existing RAC on our Data Center and We have an IBM AIX that is designed to run a Synchronous Peer to Peer Remote copy(PPRC) that used to copy data to a remote site for Disaster Recovery Purposes.
Scenario will be,
Since that our Server from the DR site have a PPRC capability it used a remote copy of our ASM-RAC (from our Data center) as storage. Is it possible that we install a Single Instance to our DR-Site and used the copy of our ASM-RAC as storage?
i'm trying to duplicate my RAC database with ASM and 2 nodes to a single node, non ASM with rman duplicate database for standby with active database on windows. The problem is i dont know how to remove RAC configuration when duplicating the database.
Here is the procedure:
On standby i've: - installed database software, - configured listener and tnsnames, - added instance service (oradim -new -sid STANDBY -intpwd PASSWORD -startmode M), - configured initora (with only db_name = STANDBY) - configured orapwd file - startup nomount
on RAC node1:
rman target sys/PASSWORD@RAC connected to target database RMAN> connect auxiliary sys/password@STANDBY connected to auxiliary database: STANDBY (not mounted)
now for the duplicate command:
RMAN> duplicate target database 2> for standby 3> from active database 4> spfile 5> parameter_value_convert = '+DATA/RAC','D:\oracle\11.2.0\DATAFILES\DATA\STANDBY' 6> set db_unique_name='STANDBY' 7> set log_file_name_convert = '+DATA/RAC','D:\oracle\11.2.0\DATAFILES\DATA\STANDBY' 8> set db_file_name_convert = '+DATA/RAC','D:\oracle\11.2.0\DATAFILES\DATA\STANDBY';
i have tried adding this parameter - set cluster_database='false' but no luck.
I am trying to design a database consolidation high-availability cluster for Oracle 11g R2 64-bit Enterprise Edition (X86-64) on Oracle Linux 6.x UEK, using Oracle 11.2.0.3 (the latest as of Aug 2012).
We don't need RAC Multi-Node now or in foreseeable future because none of the databases we run break the capacity of a single node. Likewise, we don't need to use Oracle VM to virtualise the database instances.
We plan to use SGA and PGA memory management to run multiple instances on same hardware operating on a single Linux 64-bit O/S image.Does it sound ok so far?
Two or three of 4-socket, 40-core Intel 64-bit servers with 512GB of RAM each (relatively cheap at today's HW commodity prices) will be sufficient to run all Oracle databases we have on Linux 64-bit.So the two HA options that I know of are:
(1) use Oracle Clusterware/Grid/ASM to provide for instance failover (2) use Oracle RAC One Node on top of Clusterware/Grid/ASM
As I understand it RAC One Node is significantly more expensive than the "free" Oracle Clusterware/ASM/Grid (since we own Oracle 11.2.0.3 Enterprise Licences already). So why should my employer pay for RAC One Node licence given they already own Single Instance Fail-Over and Restart protection from Clusterware/Grid/ASM ?
I also read that Data Guard 11.2 may not be supported with RAC One Node on 11.2? True? Will same Data Guard 11.2 work with a Single-Instance Failover running on Clusterware/Grid/ASM ?
-Who is running RAC One Node? Why? -Who is running Single Instance Failover with Clusterware? Why? -Who is using Data Guard with either of the above?
I have oracle 10g installed on my system and name of the database is "ORCL" for which I have schedule the incremental backup everyday. Mentioned below are the steps followed

Now I want to restore this backup to some other system with new database. How to do this recovery to some other database on new system.
I want to install oracle 11.2.0.2 single instance database on AIX 6.1, does oracle recommend separate OS user for grid infrastructure and for oracle install? how many groups I need to have for these users like oinstall, dba etc?
I would like to use Oracle Grid Infrastructure to protect a single-instance database.
I found these docs:
[URL]
I was unable to find a similar document for GI 11.2 . Do you know if such a document exists?
At the moment I only know that the GI is free if used for an Oracle Product, but I am not shure whether it can be used to protext external applications or single-instance databases
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 trying to test moving a single instance 11202 database to single instance w/ grid infra.
Here is what I've done:
1. Install a database (11202), single instance and create a database 2. Install Grid Software only (user: grid) 3. start the cluster 4. "srvctl add database -d orclsidb -o $ORACLE_HOME" to register the database with grid. 4.1> I was able to start/stop the database with srvctl command here onwards 5. configure disks using asmlib and start the asm 6. "srvctl add asm" to register asm with grid. 7. PROBLEM ... when I try to "backup as copy database format '+ASM_DATA_DG';" from oracle user it errors out as below:
RMAN> backup as copy database format '+ASM_DATA_DG';

I am using Oracle RAC 11.2.0.3 as primary database, we are going to start using Oracle data guard. So I am designing my infrastructure and planing to use Oracle 11.2.0.3 Single instance as my physical stand by database.
My question is it feasible to have my standby database as single instance while the primary is RAC? is it feasible to build my Oracle single instance standby database from the RMAN backup of the RAC primary database? Is there any restrictions (or any points to be taken into consideration) since my primary database is RAC while the physical standby is Oracle single instance?
in the below link
[URL].......
it was mentioned that primary can be RAC or single and same for standby, but my question is it feasible to have primary as RAC while standby as single instance? or it should be like each others?
The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database. Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.
I have 11gR2 GI installed on two nodes. I am trying to convert a 10g single instance (uses ASM) database to RAC and getting this error. I am trying using 12c as well as manually by using rconfig.
[main] [21:19:15:145] [ASMInstance.initialize:135] First record =[Ljava.lang.String;@958bb8 java.lang.NullPointerException at oracle.sysman.assistants.rconfig.engine.ASMInstance.initialize(ASMInstance.java:153) at oracle.sysman.assistants.rconfig.engine.Step.execute(Step.java:283)
We've been administering a multiple instance production dB server with 3 different versions of Oracle installed.Currently, each of Oracle version had corresponding listener.Oracle 9i had 2 instances, 10g 6 instances & 11g 2 instances also.how I can integrate this 3 listeners into 1.
we are using dataware house of huge amount of data I want to take backup using rman so that I restore oracle instance and specific tablespace only not full database
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?
Oracle VM 2 Node RAC cluster Oracle 11G 11.2.0.3.0 Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5
We are managing a huge amount of data warehouse on oracle 11.2.0.3.0. We need to take backup using rman of some tablespace not the whole database backup. we need a backup strategy in which we can restore the backup of some tablespace plus oracle instance if any disaster occur.
I have taken backup using rman on test db of system , sysaux , user tablespace then i restore these tablespace successfully and make the remaining tablespace offline , but while open the database it show me below error.
My question is how i backup using rman so that in case of disaster i restore oracle instance plus specific tablespace not full database.

We have 11gR2 2 node RAC on Linux. ASM and OMF is used for database. The database on it is backed up using RMAN. We want to test the RMAN backup by restoring it to a new database on same server.
I just duplicate my PRODUCTION database to TEST database (11.2.0.1 both) on windows 7.
I just create a backup from PRODUCTION:
RMAN> backup full database format ='C:Usersmy_usermiBBDDflash_recovery_are aTESTdatabase_%U';and controlfile backup:
RMAN> backup current controlfile format='C:Usersmy_usermiBBDDflash_recover y_areaTESTCONTROL_FILE_%U';now i'm trying to restore this backup into TEST with this script:
RMAN CONNECT TARGET / STARTUP NOMOUNT; SET DBID 486238190; #DBID of TEST database RUN
[Code]....
but i'm having a similar error when i tried to duplicate both databases ( post -->Error duplicate databases fallo de la recuperaci¾n del medio fÝsico canal liberado: c1
