Restore procedures of 2 node RAC

I have 2 node RAC running 11gr2 (11.2.0.2), linux RHEL 5.x in my test server using Oracle VM. This set up has 5 diskgroups in ASM (ocrvote1, ocrvote2, ocrvote3), data, fra. Both data and fra are in externally redundancy and ocrvote1-3 in normal redundancy. As i'm getting ready to test the recovery procedures of the whole setup, I wanted to check here to see, if i have covered the necessary bits and not missing anything obvious.
I will be taking full backup of database and md_backup of disk groups prior to testing these procedures. Below is the list of procedures i had come up, for getting the system restored in shortest time frame. If you think i can cut-down the time even further, would appreciate your inputs.
-- Install OS via jump start on all nodes.
-- Partition disks same set of disk and give similar names as before.
-- Stamp disks with asmlib and present them to all nodes
-- Install GI and RDBMS homes
-- Bring up ASM with OCRVOTE diskgroup on all nodes. OCR and voting disks will be created as part of ASM setup.
-- Restore data and fra dg from backup using md_restore
-- Restore latest backup from tapes or disk in to FRA
-- Restore and Recover database via Rman.
Thanks
Steve

Very good point Sebastian. I guess i need to replace OCR created from new GI cluster install with OCR from backup right, unless you say i can restore OCR from backup while building the new GI cluster. If so, can you point to me to link or documentation in doing so.
I was also thinking about using clones of GI and RDBMS home instead of making fresh install as part of the restore procedures. Is that an option?
If i have all the storage partitions intact from previous install and if have to restore the system without any data loss, anything different i should be doing here.

Multiple copies of same database on a 2 node RAC server - How to merge ?

I currently have multiple copies of the same database running on a 2 node Rac system. I am looking for a way to combine them into 1 large database but keeping the data separate.
The databases are copies of production for testing, development and a yearly "historical" databases .
All the databases are created from production, and generally have the same schema's , tables, procedures, etc however may be different versions and need to be.
Is There a way to use one large database and logically split all the different versions of the same objects into their own space in one database ? The structure cannot change as the database is for a 3rd party's Forms application the relies on the objects not changing names etc.
Ideally I am looking for a solution that will allow the forms application to connect to "test" and "historical" copies of our production database separately in the same database container.
Thanks for any direction.

2 Node RAC standby database

Hi,
I am planning to create a 2-node RAC physical standby database which uses ASM from 2-node RAC production database. I am familiar with RMAN duplicate (11g) network based backup to create the physical standby database, but not sure how this will work to create 2-node RAC standby with ASM.
Could any help me with the document ID which describes how to create a RAC standby database using ASM as storage.
Source:
OS: Linux 64 bit
Oracle: 11.2.0.1
RAC/ASM: yes/yes
Target:
OS: Linux 64 bit
Oracle: 11.2.0.1
RAC/ASM: yes/yes
Thanks in advance!!
Regards,

Hi
You can follow following...
1.Install crs.
2.Create ASM instance at standby site...
3.Prepare parameter file for standby database.
4.start database instance in one node at nomount state..
5.create standby control file at primary database...
6.Copy and paste created control file at primary to standby site..
7.Copy control file at file system and modify location of control file at init<SID>.ora.
8.start standby database mount state..
9.create backup text backup controlfile at primary site...
10.shutdown standby database,change location of controfile inside ASM.. and place nomount state...
11.Create controfile through text backup controfile...
12.backup primary db and paste it in standby site..
13.Use RMAN to place datafile inside ASM..if you not using RMAN for backup and restoration purpose..
14.start standby database in mount state and recover through MRP or foreground process..
15.use SRVCTL to register ASM instances..database and database instances.
For standby database of RAC..there can only be one node up...So..remember you can start instance of one node only...
Hope this will help U.

Node rac disappeared

Hi,
RAC 2 nodes --> 11gr2 (11.2.0.3)
OS= RHEL 5
i was trying to reconfigure RAC because we want to change bond0, bond1 to eth0,eth1. I was following this post:
https://forums.oracle.com/thread/582406
I stopped nodeapps, asm, database and all was ok, but when i was writting the operations in node 1 i had a mistake and wrote "/opt/11.2.0/grid/crs/install/roothas.pl -verbose -deconfig -f" because i used ctrl*v and this sentence i used in other server (nothing to do with this).
The problem now is that when i tried to reconfigure again with "/opt/11.2.0/grid/crs/install/roothas.pl -verbose" i can't :

Questions about adding a 3rd node on a 2-node RAC cluster

Hello,
I have created a 2-node cluster on 1 VMServer machine following the steps as described in RAC11gR1-OVM-template-TestConfiguration.pdf
Now want to add a third node as documented in Appendix B of this document, but this is not clear to me.
Here it is stated in step 7: "Do not run this procedure on a node with RAC software already configured.", while on the other hand step 9 says you need to run the Add Node procedure with the -noCopy option since the software is already loaded on the new node. This seems a conflicting message to me.
Can anyone clarify this?
Can't I just add a node using this procedure when you already have a 2 node cluster up and running?
Thanks,
Klaas.

Klaas,
Step 7 says to run on the new node this to setup the network:
"Invoke the network configuring script in silent mode as root on the new VM:
# /u01/clone/netconfig.sh -n3
Flag -n3 means 3rd node, -n4 would be 4th node, etc. Do not run this procedure on a node with RAC software already configured."
Step 9: says to run addNode.sh, as normally in the documentation, this is run from existing cluster member. You need to add the -noCopy flag so that software doesn't get copied to the new VM, since the software is already there, it is not configured or running yet, but the software is there.
In such procedures it's often the case you need to run some commands on existing, and some on new node(s). I think the misunderstanding is that software existing on the VM doesn't mean it's running or configured.
This entire process is fully automated in the 11.2 templates.

Multi-table INSERT with PARALLEL hint on 2 node RAC

Multi-table INSERT statement with parallelism set to 5, works fine and spawns multiple parallel
servers to execute. Its just that it sticks on to only one instance of a 2 node RAC. The code I
used is what is given below.
create table t1 ( x int );
create table t2 ( x int );
insert /*+ APPEND parallel(t1,5) parallel (t2,5) */
when (dummy='X') then into t1(x) values (y)
when (dummy='Y') then into t2(x) values (y)
select dummy, 1 y from dual;
I can see multiple sessions using the below query, but on only one instance only. This happens not
only for the above statement but also for a statement where real time table(as in table with more
than 20 million records) are used.
select p.server_name,ps.sid,ps.qcsid,ps.inst_id,ps.qcinst_id,degree,req_degree,
sql.sql_text
from Gv$px_process p, Gv$sql sql, Gv$session s , gv$px_session ps
WHERE p.sid = s.sid
and p.serial# = s.serial#
and p.sid = ps.sid
and p.serial# = ps.serial#
and s.sql_address = sql.address
and s.sql_hash_value = sql.hash_value
and qcsid=945
Won't parallel servers be spawned across instances for multi-table insert with parallelism on RAC?
Thanks,
Mahesh

Multiple databases/instances on 4-node RAC Cluster including Physical Stand

OS: Windows 2003 Server R2 X64
DB: 10.2.0.4
Virtualization: NONE
Node Configuration: x64 architecture - 4-Socket Quad-Core (16 CPUs)
Node Memory: 128GB RAM
We are planning the following on the above-mentioned 4-node RAC cluster:
Node 1: DB1 with instanceDB11 (Active-Active: Load-balancing & Failover)
Node 2: DB1 with instanceDB12 (Active-Active: Load-balancing & Failover)
Node 3: DB1 with instanceDB13 (Active-Passive: Failover only) + DB2 with instanceDB21 (Active-Active: Load-balancing & Failover) + DB3 with instanceDB31 (Active-Active: Load-balancing & Failover) + DB4 with instance41 (Active-Active: Load-balancing & Failover)
Node 4: DB1 with instanceDB14 (Active-Passive: Failover only) + DB2 with instanceDB22 (Active-Active: Load-balancing & Failover) + DB3 with instanceDB32 (Active-Active: Load-balancing & Failover) + DB4 with instance42 (Active-Active: Load-balancing & Failover)
Note: DB1 will be the physical primary PROD OLTP database and will be open in READ-WRITE mode 24x7x365.
Note: DB2 will be a Physical Standby of DB1 and will be open in Read-Only mode for reporting purposes during the day-time, except for 3 hours at night when it will apply the logs.
Note: DB3 will be a Physical Standby of a remote database DB4 (not part of this cluster) and will be mounted in Managed Recovery mode for automatic failover/switchover purposes.
Note: DB4 will be the physical primary Data Warehouse DB.
Note: Going to 11g is NOT an option.
Note: Data Guard broker will be used across the board.
Please answer/advise of the following:
1. Is the above configuration supported and why so? If not, what are the alternatives?
2. Is the above configuration recommended and why so? If not, what are the recommended alternatives?

Hi,
As far as i understand, there's nothing wrong in configuration except you need to consider below points while implementing final design.
1. No of CPU on each servers
2. Memory on each servers
3. If you've RAC physical standby then apply(MRP0) will run on only one instance.
4. Since you are configuring physical standby for on 3rd and 4th nodes of DB1 4 node cluster where DB13 and DB14 instances are used only for failver, if you've a disaster at data center or power failure in entire data center, you are losing both primary and secondary with an assumption that your primary and physical standby reside in same data center so it may not be highly available architecture. If you are going to use extended RAC for this configuration then it makes sense where Node 1 and Node 2 will reside in Datacenter A and Node 3 ,4 will reside in Datacenter B.

I am trying to restore this backup that is on tape (EMC Networker) to a different node. I can do this outside of Networker without any problems. However, when I try to get the backup from tape I have this issue:
1. initPROD.ora is created and modified accordingly on a new server
2. Export sid, startup nomount on new server
export ORACLE_SID=PROD (on this new server)
*rman target /*

Do a list command to see if the controlfile backup is on tape.
RMAN> list backup of controlfile;
I suggest you to read the manual of EMC Networker or call EMC on how to restore the database to another node. I am using Veritas Netbackup, it may be similar to EMC Networke for your reference. There are a few things that need to be followed when you restore database to another node:
1) set DB_ID, which you have done
2) set NB_CLIENT (in your case NSR_CLIENT) to the primary node from where backup was taken
3) configure the backup server to allow redirect restore between the two nodes.
Hope this helps.

ORACLE 10G 2 Node RAC on servers AB to 3 node 11GR2 RAC on new servers XYZ

Hi Gurus ,
We have a business requirement to upgrade existing oracle 10.2.0.4 2 Node RAC on servers A,B (HP UX 11.31 ) to 3 Node ORACLE 11GR2 on new Servers X,Y and Z(Linux and servers are from different vendor)
We don't have ASM.We have RAW file system
Now this has to be done with near zero down time.This is a very busy OLTP System.Golden Gate is not an option as Management is not going for it this time.
Storage is same for everything.I am thinking of the following ways.Please let me know if you have any better plan or if you want to correct my existing plan
Initially i thought of this way and i immediately answered myself
Plan A
1 ) Storage copy (BC etc..) exising 10g RAC Database files on A,B to new volumes allocated to Servers X,Y and Z ( I don't think it's possible as OS is different.I am not sure whether copying this way is possible or not , even if possible i am not sure whether new OS can identify these files or not)
2 ) upgrade 2 Node 10.2.0.4 on X,Y to 11GR2 .
3 ) Add a Database Node on Z
Plan B is
1) Build 3 Node brand new 11GR2 on X,Y and Z
2 ) Plan for how can you replicate the data ( This has to be a logical way)
a ) RMAN - Very time consuming as this is >50 TB Database
b) Golden Gate - Not an option.Even if we can use it , i see there are so many logical issues with golden gate
c) Expdp/impdp - forget about it :)
d) physical standby (Versions are different.If it is same version and Same OS then would have been best bet)
What would be the ideal way to do this with minium down time and with out golden gate
I think something can be done on the lines of PLAN A itself.
Requesting your help Gurus
Thanks

Hi,
Have you considered possibility to setup a logical standby and do rolling upgrade ?
Please have a look at the following:
1) http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-transientlogicalrollingu-1-131927.pdf
2) http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-upgrades-made-easy-131972.pdf
If you can practice on test setup, it looks a faster option than the others.

My daughter forgot her passcode, phone is disabled. I attempted restore procedures by placing phone in restore mode and syncing to original computer, but it still says I need the passcode and does not offer option to restore as new. Verizon can't help.

My daughter forgot her passcode. Phone is now disabled. I attempted restore procedures by placing phone in restore mode and connected it to the computer / itunes with which it was originally synced. itunes recognized phone in restore mode and said I must restore. I clicked restore, restore and update. Update began, itunes recognized the device by name and gave error message that stated I must have the passcode to restore. There was no option to restore as new. I attempted to restore the iphone 4s on another computer by instaling itunes, but same error messages appeared. I contacted Verizon and they said they could not help me. The nearest apple retail store is over 40 miles away. PLEASE HELP!

If You Are Locked Out Or Have Forgotten Your Passcode
iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
iOS- Understanding passcodes
     If you have forgotten your Restrictions code, then follow the instructions
     below but DO NOT restore any previous backup. If you do then you will
     simply be restoring the old Restrictions code you have forgotten. This
     same warning applies if you need to restore a clean system.
A Complete Guide to Restore or Recover Your iDevice (if You Forget Your Passcode)
If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
Follow these steps to restore your device:
     1. Verify that you are using the latest version of iTunes before attempting to update.
     2. Connect your device to your computer.
     3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
     4. Select the Summary tab.
     5. Select the Restore option.
     6. When prompted to back up your settings before restoring, select the Back Up
         option (see in the image below). If you have just backed up the device, it is not
         necessary to create another.
     7. Select the Restore option when iTunes prompts you (as long as you've backed up,
         you should not have to worry about restoring your iOS device).
     8. When the restore process has completed, the device restarts and displays the Apple
         logo while starting up:
           After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
          to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
          iOS, keep your device connected until the "Connect to iTunes" screen goes away or
          you see "iPhone is activated."
     9. The final step is to restore your device from a previous backup.
If you can not restore your device then you will need to go to recovery mode.
Placing your device into recovery mode:
Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
     1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the other end
         of the cable connected to your computer's USB port.
     2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the
         red slider appears, then slide the slider. Wait for the device to turn off.
          If you cannot turn off the device using the slider, press and hold the Sleep/Wake
          and Home buttons at the same time. When the device turns off, release the Sleep/Wake
          and Home buttons.
     3. While pressing and holding the Home button, reconnect the USB cable to the device.
         The device should turn on. Note: If you see the screen pictured below, let the device
         charge for at least ten minutes to ensure that the battery has some charge, and then
         start with step 2 again.
     4. Continue holding the Home button until you see the "Connect to iTunes" screen.
         When this screen appears you can release the Home button.
     5. If necessary, open iTunes. You should see the following "recovery mode" alert:
     6. Use iTunes to restore the device.
If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
Additional Information:
Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.

Converting single instance database(11gr2) supporting EBS 12.1.3 to 2 node RAC on RHEL.

Hi We are in the process of converting single instance database(11gr2) supporting EBS 12.1.3 to 2 node RAC on RHEL. Which version of RHEL is better? if its 6.x then x?? The oracle document only says RHEL update 6.
thanks in advance.

Hi,
Yes you can use any version but i recommend you to use 6.2

11gR2- webutil upload file to AS on two nodes RAC?

Hellow experts plz help with the following issue,
we are using 11gR2 forms on two node rac,webutil configured on both nodes. upload/download files to AS folder(UP_FILES) using our forms. node 2 is actually replica of node 1(forms,reports,UP_FILES). we are now facing a problem that the form which upload file to AS, only upload that to the node from where it is running say if it is running from node1 then it upload files to folder UP_FILES on that node( as the entry in webutil.cfg file) but we want that UP_FILES folder should be synced with each other on both nodes and a form running whether from node1 or node2 upload the file to both nodes at time.
How this will be accomplished?
--------webutil.cfg entry
transfer.appsrv.read.3=D:\UP_FILES
transfer.appsrv.write.3=D:\UP_FILES
-----FORM UPLOAD CODE
      IF :CONTROL.FILE_LOC IS NOT NULL THEN
        acyr3 := :CONTROL.TXTVOUCHERNO||'-'||acyr2 ;
       FILE_RESULT := WEBUTIL_FILE_TRANSFER.CLIENT_TO_AS_WITH_PROGRESS(CLIENTFILE=>:CONTROL.FILE_LOC,
       SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'UPLOAD TO DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT' );
      END IF;
--FORM DOWNLOAD CODE
        FILE_RESULT := WEBUTIL_FILE_TRANSFER.AS_TO_CLIENT_WITH_PROGRESS
             CLIENTFILE=>'D:\UP_FILES\'||acyr3||'.PDF',
        SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'DOWNLOAD FROM DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT'
             CLIENT_HOST('rundll32.exe url.dll,FileProtocolHandler D:\UP_FILES\'||acyr3||'.PDF');
             IF FILE_RESULT THEN
message('File downloaded successfully from the Application Server');
END IF;

Well, you're uploading the file to one node, so this is no surprise. What you can do is to store your file on a shared folder (which might be a bit tricky on windows) or synchronize a folder between your nodes. Unfortunately Forms can't access ASM directly (assuming you are using ASM), so you can't store your files directly in ASM where it would be accessible from both nodes.
cheers

How to add a second database along with existing two node RAC environment

Hi,
I was wondering if anyone can help me with this.
My Environment:
1. Two node RAC Cluster database (11.2.0.2) with ASM running perfectly (Oracle Sid = test-1)
2. I have installed a second single instance db on node 2 (Oracle Sid = test-2) with NTFS file system for datafiles
3. Database is up and running, but I am not able to connect it from any client.
4. I am getting ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
5. Database (test2) is registered with grid LISTENER
5. TNSPING from client machine response is ok
Am I missing something here, happy to provide more info if requested.
Thanks,

How to create second database at ASM in 4 node RAC system

Hi Experts,

we want to add second database at ASM in RAC system based on manager decision.
how do I add second database in ASM with exist database?
Do I need to created new ASM insatnce?
how to create two new diskgroup? is it under existing ASM instance or new ASM instance?
how to reset ASM properity to support ( or new) ASM instance and two database?
Do I need to configure AMS again after added more space into ASM?
I could not find ducument that add seconf database into ASM in RAC system.
I want add second database by dbca. any experience for add second database in ASM RAC ?
Thanks for help!

Hi... I'm in the same situation.
I need to add a new second database on a RAC installation based on already available ASM instance.
I'm using 11gR2.
I read your suggested documentation. Then I typed asmca and analyzed my asm configuration:
As you can see I have a DISK GROUP NAME with several FREE space.
!http://img522.yfrog.com/img522/8405/dbca20100203173248.jpg!
If I select Volumes tab the following is my current configuration:
!http://img682.yfrog.com/img682/562/dbca20100203173343.jpg!
Selecting Create button, I can insert some values as you can see:
!http://img403.yfrog.com/img403/9889/dbca20100203173403.jpg!
First question:
Is this the right way to create space for a new database ? Consider that running dbca.. no DISK GROUP NAME is available.
Second question:
When I created my first database on this DISK GROUP NAME no volumes were created. Why now I have to do it ? Is this necessary to really separate datafiles coming from different databases ?
