Possible Strategies For Restoring A Single Tablespace From Instance A To B
Jan 17, 2013
SO....: Win 7 64bits
DB....: Oracle 11.2.0.3 EE 64 bits
In my notebook, i have 2 instances (orateste and ora11). They are all for testing purpose. I don't know what happened but, a problem in a partition of my SO made the Oracle software unavailable. I cannot start instance orateste. Even the windows service related to the instance have disappeared from services.msc. What i want to do is to restore only one tablespace from instance orateste to ora11. I have a full rman database backup from D-1.
1) Restore the entire database (orateste - 11.2.0.1) to ora11(11.2.0.3)?
2) Is there a way to restore only one tablespace, between instances and versions?

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.

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';
Starting backup at 24-AUG-12

My database is OLP system.
My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.

I am planning a single instance database using Oracle 11gR2 Enterprise. The instance will run on OEL 5.5 which is on VMWare ESX 3. All disk space will be provisioned as VMDKs. The physical disk comes from a NetApp 7 controlled SAN with multiple disk arrays (one fast disk array and one slower disk array) using NetApp's RAID-DP (RAID-6).
Is there any benefit to using ASM in this single instance configuration ? It seems the data is already being striped, balanced, deduped, and (somewhat) protected by ESX, NetApp, and RAID-DP. NetApp SnapShot provides additional back-up options.
I am thinking without ASM, I could have one 1 TB LUN, say /u01, for the binaries, data files, and management files on the fast disk array and one 1 TB LUN, say /r01, for the flashback recovery area and all other recovery related files on the slower disk array. With autosize capabilities, any of the files can expand as needed up to the 1 TB capacity. 1 TB per disk array is the resource allocation for this instance.
With ASM, on the fast disk array I would have one 32 GB LUN for binaries and other files which must be outside of Oracle's CFS under ASM and then four 248 GB LUNs to create the ASM disk group DATA. On the slower disk array I would have four 256 GB LUNs to create the ASM disk group FRA.

Initial situation: Oracle 10g database single instance on Windows 2008 (datafile within NTFS partition)
Final situation: same database upgraded to Oracle 11g r2 on a two nodes RAC on Windows 2008 (datafile within ASM)
In your opinion, is this the best way to achieve the job ?
1) on the two nodes install grid 11gr2, asm, rdbms 11g r2 (SE)
2) export full from 10g
3) create a new empty 11g r2 database in the RAC 11g r2 infrastructure with the same tablespace layout of 10g database
4) import full from 10g to 11g r2

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.
ERROR at line 1:
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: 'C:APPADMINISTRATORORADATASYSTEMSYSTEM01.DBF'

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?

Primary:
2 NODE RAC Cluster/Linux x86-64/11.1.0.7.4 RDBMS
Standby server:
Brand new box, and I installed 11.1.0.6 (software only)
I have a brand new box set-up for a single-instance standby database, and I have installed 11.1.0.6 software only.
Do I need to patch 11.1.0.6 to 11.1.0.7 before I send a copy of the primary over to be set-up as a standby? If so, how do I patch 11.1.0.6 without having a local database in place as this server will only be used for a standby? Can patching the oracle_home only be done?

I am configuring Grid Infrastructure 11g2 on node A, one of two cluster nodes, and getting the following message:
[INS-40916] Single-instance versions of Cluster Synchronization Services (CSS) are detected.
I executed runInstaller and installed software-only on both A and B nodes. It apparently the other node has already CSS instance running, and maybe caused by the installation.I remove the software from A first?
How do I stop CSS on the node A, and let the configuratoin to continue on this node B

I would like to use Oracle Grid Infrastructure to protect a single-instance database.
I found these docs:

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

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 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 am working on ASM as i am bit confused to decide ASM Disk strategies in production Environments. For Ex:-
1.Normal Redundancy ( Allows 2 Mirror Groups ) :-
I have created Normal_DG Diskgroup with 4 Disks
Disk1-------------------
Disk2 ------- |
|--->FG2 ----> FG1
Disk3 ------- |
Disk4-------------------
According to my understanding , if Disk1 Fails Disk4 facilitates normal operations. When there is space crunch it operates in reduced redundancy . Am i right ?
2.I have got 4 Disks in one group (i.e from Disk1 To Disk4 ) i have not defined any failure group and as per my understanding all disks will be added to its own failure group without mirroring and striping.

The best way to structure my schemas within a single Oracle instance to support multiple project development. At the moment, within an Oracle instance I have Area_Dev and Area1_Test schemas, with the intention that Project Xv1.0 would use Dev schema for development and Test schema for testing.
Lets say I want to start on Project Xv2.0 development while I am still finalizing Project Xv.10 development what is the best way of accommodating that, without creating individual schemas for each project?

My context on our servers is the following one:
- one ASM instance
- X DB instances
- each DB instance uses 2 or more dedicated diskgroups from the ASM instance
- there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view
- the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?
