Implementation Of RAC To Non-RAC (Single Instance With Existing ASM-RAC As Storage)
Jan 13, 2013
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 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'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 have 11.1.0.7 instance running and got more 300G of storage available for the database. I would like to know what are the steps to add these disks/storage to the existing DATA asm disk group?
when i configure monitor target in GC12C,1 find i can not add asm instance target, and i use scan ip in 11GR2 rac ( two nodes )the problem is plublic IP's 1521 port not accept connect request from remote IP
error from gc12c Failed to connect to the ASM: IO Error: The Network Adapter could not establish the connection The Connect Descriptor was (DESCRIPTION=(ADDRESS_LIST = (ADDRESS=(PROTOCOL=tcp)(HOST=172.20.101.78)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=+ASM1)(INSTANCE_NAME=+ASM1)(UR=A)(SERVER=DEDICATED))) [code]....
how can i let GC12C see ASM instance on each node in cluster??
My cluster have two node.Data diskgroup uses normal redundancy.Priamry disks are located in one storage.Fail group disks are located in another storage.When we close the failgroup disks' storage the 2nd instance restart.After automatically restarted everything goes well.I want to know why does the 2nd instance restart?Is it normal?
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
i have created an another instance on a single machine i got error when starting up a new one - error starting up database in exclusive mode so i shutdown older database instance , to start new one now is it possible to run both instance parallel?
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?
There is a Single Instance production server Oracle 9iR2 [9.2.0.8] OS HP-UX PARISC 11i v1 to RAC.
Now we want to migration this server with minimum downtime to Oracle 11gR2 [11.2.0.2] in RAC environment OS HP-UX 11i v3 Itanium DOwn time must be minimum. what will be the procedure ?
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 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 am not able to find any document that shows steps to create a SINGLE INSTANCE LOGICAL STANDBY database for a 2 NODE ORACLE RAC database. I have found documents for RAC to Single Instance Physical standby database. But not for Logical Standby.
Details:
OS: Redhat 5 DB: 10.2.0.4(shared file system, not using ASM/Standby also file system) Status: Single instance physical standby database created, need to convert it to Logical standby.
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.
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?
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.
I'm planning to upgrade a small database (~150GB) from 10.2.0.3 on windows 2003 23bit to 11.2.0.3 RAC on Linux 5.8.The database contains oracle spatial too. A suitable method and link to document to be followed.
Currently, I am using oracle 10g and getting foolowing error
"PLS-00436: implementation restriction: cannot reference fields of BULK In-BIND table of records"
When trying to access attribute in record-collection inside FORALL. I know its prohibited in 10g but allowed in 11g. My questions is how can we achieve this in 10g. I will rephrase my problem:
I have three record-collections say rc1, rc2 and rc3 and I need to put all these record-collection inside final record collection say FC using FORALL
My organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?
