RAC 11g SCAN and DNS

Hi,
Do I need to consider and resgister SCAN with DNS or just use SCAN as VIP before I install RAC 11G R2 ?

Hi,
In case you decide to use the Grid Naming Service (GNS),the GNS daemon will allocate three IP addresses from the range of addresses offered by the DHCP server. The IP addresses are Address records in DNS that resolve to the SCAN name in a round robin fashion
In /etc/hosts on each node of the cluster – a single IP for the whole cluster. Helps bypass the OUI installer limitation of DNS defined SCAN.

Oracle 11gR2 RAC VM and SCAN and DNS and /etc/hosts (two) setup questions

Hi,
I am looking forward to setting up two Oracle 11gR2 RAC instances
on my Oracle VM test machine.
I plan on using the Oracle 11gR2 RAC VM template.
I want the final Oracle 11gR2 RAC instances to have SCAN that uses DNS.
The DNS will be pre-installed in the JeOS.
My first simple question about the setup is the following.
In my DNS name file, for example,
/var/named/chroot/var/named/milkyway.univ.db
do I need to provide the racnode1 and racnode2 information,
for example,
# DNS name file (snippet)
myjeos IN A 192.168.1.150
racnode1 IN A 192.168.1.161
racnode1-vip IN A 192.168.1.163
racnode2 IN A 192.168.1.162
racnode2-vip IN A 192.168.1.164
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
Or, can I just provide only the rac-scan information
# DNS name file alternate (snippet)
myjeos IN A 192.168.1.150
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
What I am getting at is the following.
Within the install process, will racnode1, racnode1-vip, racnode2,
and racnode2-vip host names and their IP address be written
to the RAC instances /etc/hosts files? (So I should not bother
to put them in the DNS name file like '# DNS name file alternate (snippet)'?)
Or, should I put the racnode and racnode-vip host names and IP addresses
in the DNS name file like '# DNS name file (snippet)'?
The second question is the following.
Are the cluster name and the scan name allowed to be different?
Currently, I would plan them to be different,
for example, rac-cluster and rac-scan.
Or, are they required to be the same,
for example, rac-cluster and rac-cluster.
Thank you.

We write this data out to /etc/hosts just to reduce the amount of round-trip DNS requests the cluster nodes make for themselves.
Are the cluster name and the scan name allowed to be different?They can be different.

Oracle Rac 11g R2 and Openfiler

hi all.
i am using Oracle Linux Enterprise 5.5 Openfiler 2.9 ,Grid 11g R2 and oracle Database 11g R2.
i created 3 disks ,Disk1,Disk2 and Disk3 but i gave the size to DISK2 and DISK3 40GB
and DISK 5GB plz can anyone guide me by using OPENFILER how much SIZE(GB) i can use for each DISK?

hi all.
is there any other way to work like openfiler i want to create voting disks for my rac,i used openfiler for that,
plz can anyone tell me is there any good way to create large disks for rac datas?

RAC 11g services and Parallel execution

Hello
In 11g RAC we can specify that a service is available on specific nodes and this integrates with parallel query. So if I have a query that I want to run in parallel but I only want it to run on one instance, I can connect to a service that only runs on that instance and run the query. Which is great but, I have lots of different queries to run as part of a batch processing system and I need them to execute on different nodes based on meta data.
In 10g this could be achieved by setting up instance groups and setting the current instance group as a session level parameter. Does anyone know if this is possible to achieve with services in 11g? Or am I going to need to use instance groups?
Thanks in advance
David

Hi Timur
Thank you for your reply. Although it's not recommended, I think I'll have to go with instance groups etc. as I can't see how we can use services for this particular problem.
Thanks again
David

RAC and SCAN and TNS

Hi
suppose that I have got a RAC (Oracle 11gR2) environment and my SCAN IPs are
172.21.28.115
172.21.28.116
172.21.28.117
I can define TNS name like this
RAC=(DESCRIPTION =
            (ADDRESS=(PROTOCOL=TCP)(HOST=scan)(PORT=1521))
             (CONNECT_DATA=
                (SERVICE=DEDICATED)
                (SERVICE_NAME=rac.com)
)Consider that I don't want use DNS in client side ,_But my RAC servers have a DNS for SCAN_
for example my application server can't use DNS
Now can I substitute the IPs with scan like follow example ?
RAC=(DESCRIPTION =
            (LOAD_BALANCE=YES)
            (ADDRESS=(PROTOCOL=TCP)(HOST=172.21.28.115)(PORT=1521))
             (ADDRESS=(PROTOCOL=TCP)(HOST=172.21.28.116)(PORT=1521))
             (ADDRESS=(PROTOCOL=TCP)(HOST=172.21.28.117)(PORT=1521))
             (CONNECT_DATA=
                (SERVICE=DEDICATED)
                (SERVICE_NAME=rac.com)
)Do I miss any thing if I don't use DNS in Clients?
thanks

Consider that I don't want use DNS in client side ,But my RAC servers have a DNS for SCANyou can still use VIP to make connectivity even you've configured SCAN.
entry would be same as we were using in 10g.
DB =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = tcp)(HOST = ****)(PORT = 1521))
      (ADDRESS = (PROTOCOL = tcp)(HOST = ****)(PORT = 1521))
      (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVICE_NAME = DB)
      (FAILOVER_MODE =
        (TYPE = select)
        (METHOD = basic)
        (RETRIES = 20)
        (DELAY = 3)
)

Oracle client 9i and Oracle RAC 11g

Hi,
Would appreciate to help me in following. I have installed RAC 11g on one site and on another site I have machine with installed client 9i. All traffic between them going through firewall.
Client is using by application that opening from 8 to 12 sessions to server with permanent high load. Periodically we are getting error "end-of-file communication" that means disconnections with DB.
Can it be compatibility issue between 9i client and 11g server or most probably firewall killing connections?
On the same site that installed DB, we are using 11g client and there everything working perfectly. So it can be only firewall or client 9i issue.

My version of client is 9.2.0.7. It should be compatible as per this doc:
https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=163455558495377&_afrWindowMode=0&_adf.ctrl-state=1814k31djx_120#115

SCAN RAC 11g

We have 2 node rac running with 1 databse currently. (XXX) which is running on port 1580 and having a application tier which is running successfully.
We need to add another database on the same nodes (YYY) but we need to run scan and database listener on port 1590 for ebiz application to talk to it.
But I suppose in cluster's services we can't have more than 1 scan listener.
So we propose this.
We create a new database listener running on port 1590
Scan listener keep running on 1580
We clone the database from XXX to YYY and then point local_listener to 1590 and remote listener to scan.
It will register itself and then on apps side we change the XML to point to Scan listener so it will be like this.
EBIZ running on port 8069 pointing to database running on 1580.

Hello all,
for "+why not simply add a second port to SCAN and db listener?+"
... because the fact that you can do that:
"+srvctl modficy scan_listener -p "1580,1590"+"
is considered a BUG (10633024), which means the ability to do so will go away in future (11.2.0.3).
Using SCAN with one TCP port and multiple listeners with respective ports should work just fine, if done right. For more information, see:
MOS Note 220970.1 – RAC: Frequently Asked Questions - entry: "How to use SCAN and node listeners with different ports?"
Hope that helps. Thanks,
Markus

Problem with Oracle RAC with DRCP and persistent connections

Hello,
I am having a problem that has me stumped. I cannot get SCAN, and DRCP to work together nicely.
Right now, I can connect through my scan hostname fine without connection pooling, once I enable it I start having connection time outs. I found if I specified outbound_connection_timeout in sqlnet.ora that it times the connection out to the time I set in there. If I don't set this option I get a "ORA-12170: TNS:Connect timeout occurred".
The odd thing is I can leave connection pooling on and connect to one of my rac instances individually and it doesn't experience this problem. The only time it pops up is if I combine multiple rac instances (Through the use of SCAN or tnsnames.ora) and I enable connection pooling.
I don't know which direction to go to even diagnose this, so any and all help is appreciated.
Thank you.

Hi,
You need to detail the problem. Enable TRACE SQL*NET on the server and client using note below.
How to Enable Oracle SQLNet Client , Server , Listener , Kerberos and External procedure Tracing from Net Manager [ID 395525.1]
Also you can try check this note:

Setup SCAN in DNS for Oracle Grid 11gR2

We're trying to figure out how to to setup SCAN in DNS. Any advice is greatly appreciated.
1) Our SCAN name is "ractest-scan". If our domain name is "cts.com", Are these the correct way to put them in DNS?
ractest-scan.cts.com virtual 10.122.72. 200 Fixed DNS
ractest-scan.cts.com virtual 10.122.72. 201 Fixed DNS
ractest-scan.cts.com virtual 10.122.72. 202 Fixed DNS
2) we should be able to "nslookup ractest-scan.cts.com" although we can't ping the name. Is this right?
Thanks a million.
Sam -

Hello Buddy,
Yes, you're right about it. When you setup RAC 11gr2 you will be able to ping the name too, and it will resolved by DNS randomically and back to you one of each Ip addresses that you setup on your DNS.
On your dns register also the VIP addresses and at client tnsnames.ora, put only the SCAN NAME, it will works fine, this is a great feature used by plug or unplug servers of RAC cluster!!!
Remember, don't put any scan addresses on /etc/hosts, it is not recommeded by Oracle.

Failed Hardware Scan and other issues E440

Hi all,
This is probably more rant than anything, but I wanted to give a heads up to others too.
I have a ThinkPad E440 that is a year old. From the very first time I turned it on, there have been issues. The first hardware scan (via Lenovo Solution Center - LSC) showed a warning for the Intel Dual Band Wireless-AC 7260 Local Connection Test. There were also tons of System Events that always show up in the "Configuration History" part of the LSC. You can look at the calendar and tell exactly which days I used the computer because there will be System Events generated each day. Things like app crashes and failed drivers.
In July 2014, I got the first warning for the 16 GB SSD - the SMART Short Self-Test. By February this year it showed as failed for each hardware scan (these were initially set up to run monthly).
Also the whole time I've had it the touch screen would just stop working at some point and I would have to reboot to get it working again.
I finally called Lenovo on March 30th, before my warranty expired. When I called that time, I didn't realize the hard drive failure was the SSD. So they sent me a new 500 GB drive. I also added the other things into the case when I talked to them. For the wireless issue they suggested making sure the driver was up to date. I did this and let them know when I called back that it was up to date and still having the warning. So I called them to tell them to tell them about the wireless and also that I realized it was the SSD having the failure, not the main drive. The first case had already been closed even though none of the other items were addressed.
So they opened another case (this is #2). They said to mail them the laptop since the wireless issue would probably be on the board and it wasn't something I could fix myself. They sent a box with a prepaid overnight shipping label. I was very sick for a few days so I sent it back to them on April 10th (a Friday). Via UPS I saw it was delivered on Saturday. Work was performed on it Monday, April 13th and sent back to me that very day. I received it on April 14th. This part of the service has been excellent - very fast response.
Being in IT, I included a letter with the laptop that outlined the issues that should have been in the case. I also printed the hardware scans and what the system events looked like.
When I got the laptop back, the sheet inside said they had replaced the Speaker because of Distorted Sound. This was not even on the list even though I had noticed it. I didn't even power up the laptop before calling them again - yes, I was furious! Plus our power was out...
So this was noon on the 14th. They opened case #3 and sent me ANOTHER BOX so I could send it back.
After our power came back on the 15th, I powered up my laptop. I opened the browser (I have it set to restore the previous session) and there was a sexually explicit video on YouTube. I opened the other browser and there was a different video on YouTube. So this person was watching YouTube instead of fixing my laptop. I looked through both browser histories and there was quite a bit of activity while my laptop was at the repair center... I ran the hardware scan - still failed and a warning for the wireless. They really hadn't done anything.
I also found two pictures of the repair person in the recycle bin...
So I called back. I was LIVID! They opened another case (this is #4). And sent me ANOTHER BOX. I finally learned the other day that once a case is opened, it cannot be edited or added to at all. Instead, they close the other case and open a new one. I guess their turnaround time for closing cases is excellent! I've never seen a system like that - and I've used a lot of them.
I got a really nice, patient fellow on the line. He took all my info (again). I emailed him the pictures, screen captures of the YouTube videos, the letter I had sent - everything. He entered as much into the new case as he could - he talked to one of the supervisors to make sure he did it right. Somehow he flagged it so that the laptop would get more attention (time) at the repair facility. He also opened a separate case (an escalation ticket?) for a supervisor to call me regarding the person's conduct at the repair facility. He said they would call me that day. (It's now the 25th and I've never heard from anyone)
So, he sent me ANOTHER BOX. I've built up quite a stack of them.
Our power was out AGAIN from the 17th through the 19th (don't get me started).
I noticed a hardware scan had now gotten a failure on the main hard drive. So I called them on the 21st to add this to the case before sending the laptop back. The girl said they can't add anything to an existing case or edit it at all once it's opened. She would have to open a new case and SEND ME ANOTHER BOX. I told her to forget it because I was ready to send it in and didn't want to wait for another box. I also asked for a status on that "escalation case" where the supervisor was supposed to call me. In order to do this she, yes, wait for it, had to open ANOTHER CASE!! So they would know I wanted a status. I'm completely dumbfounded.
So I sent it back on the 21st. This time I practically wiped it. I had already removed all my files the last time, but I had left my bookmarks and browser history intact. I set up a guest logon with admin privileges. I updated my letter and printed off more stuff to include with the box. On one sheet I had only the case number, the serial number and machine type. On another sheet I had "DO NOT SEPARATE THIS PAPERWORK FROM THE LAPTOP" and the case number. I put this sheet on top (The guy on the 15th said my letter and stuff may have gotten separated from the laptop once it was delivered to the repair facility). I used a ton of staples so it would all stay together. I included in my letter the failure on the main hard drive and asked if they could look at it. I wrote about having to open a new case if I wanted to include it.
They received it on the 22nd. A nice gentleman from the repair facility called me that day asking about the password. that. was. written. on the sheet they have you fill out. I told him what happened last time and also mentioned the hard drive failure and asked if he could look into it. He said they would.
I received my laptop back yesterday morning.The sheet that came with it said they had "replaced the following parts to complete the repair of your laptop."
Part Description                                           Symptom
IMAGE                                                             Replaced due to engineering change
System board                                                 Network card error
Hard disk drive                                                Network card error
ECA-WIRELESS                                            <no symptom listed>
There was also a sheet saying they had installed a factory preload of software and I needed to install Lenovo and Windows updates.
When I booted it up, the first thing I noticed, in the lower right corner was:
Windows 8.1
SecureBoot isn’t configured correctly
Build 9600
I ran a hardware scan. Well, I tried. It stopped part way through and said it finished successfully but most of the tasks showed up as cancelled. I tried to run it again - issues - rebooting ensued. It said the LSC wasn’t available and that I should try again or reboot.
Tried several times. Then got what I guess is the new BSOD - kinder, gentler:
Your PC ran into a problem and needs to restart. We're just
collecting some error info, and then we'll restart for you. (xx% complete)
If you'd like to know more, you can search online later for this error: DRIVER_CORRUPTED_EXPOOL
Even though the LSC said my Lenovo files were all up to date, I ran the Update. And first I had to download a new version of Update. Then I downloaded all of the Lenovo updates and installed them (there were quite a few). The BIOS update failed. While I was doing the Lenovo downloads, I got a light blue screen but no text (I was out of the room so I'm not sure what happened). Did CTRL-ALT-DEL and it shows only IE and Task Manager as applications that are running. Could not “Switch to” IE. Hitting window key to go to start didn't do anything. So I had to restart.
By 3pm yesterday there were 34 system events in the configuration history.
I ran the hardware scan again after I updated the Lenovo files, and you guessed it! Failure on the SSD (SMART Short Self-Test) and warning on the wireless. Nothing had changed. Except hardware scan is acting different than it did before I sent in the laptop for repairs. When it finishes, it instantly closes and just shows 100% complete. When I click on "see last results" it shows a screen called
Log Information,
Canceled 04/24/2015 n:nn pm
You have not done a hardware test on your computer
And the calendar in LSC only shows the very first hardware scan I did on Friday. Even the hardware scan screen shows the date and time of the last scan. It also shows the error code. In order to see exactly what is failing, I have to sit there and watch it very closely and snap a picture of the screen as soon as the error (or warning) shows up.
When I would try to run Windows update, it would hang up PC Settings. I couldn't even kill it using task manager because it didn't show up as a task. During this, I got a flag saying the firewall wasn't turned on. I tried to turn it on, but clicking on Turn on Windows Firewall didn't do anything. I tried to setup my Microsoft account but that just hung too.
I ended up running Windows Update FOUR TIMES to get all the updates installed. Every time I ran it, it said "Done!" and I would run it again and more would show up. The last time was this morning.
At some point, the error about SecureBoot went away.
Then, I created a bootable BIOS update disk. Following the ReadMe instructions, I went through ThinkPad Setup and verified several values. Of note:
Secure Boot was DISABLED. According to the ReadMe file, this should be ENABLED in Windows 8.1. I enabled it.
Under Startup/Boot, according to the ReadMe that came with the BIOS update, UEFI/Legacy Boot is supposed to be set at UEFI Only for Windows 8.1. Mine was set to "Both". I changed it.
In Startup, OS Optimized Defaults was DISABLED, even though it says right there (and in the BIOS update ReadMe) it should be ENABLED to meet Microsoft Windows 8 Certification Requirement.
After these updates, I flashed the new BIOS.
Then, I ran hardware scan again...
Now I have TWO failures on the SSD: Random Seek Test and SMART Short Self-Test. Great.
In the Event Viewer (that I recently discovered), it says my disk has a bad block. It just says The device, \Device\Harddisk\DR1, has a bad block. I assume this is the SSD...
There are 867 events in the event viewer - Critical, Error, and Warning...
Fifty-two of these are from October 7, 2013 - before my little laptop was a glimmer.
The rest are from when Lenovo had it and yesterday and today.
64 of them are the disk error.
341 are from DeviceSetupManager. 65 of those are from failed driver installs. 69 are for not being able to establish a connection to the windows update service. 64 are from not being able to establish a connection to the Windows Metadata and Internet Services (WMIS).
3 times it's rebooted without cleanly shutting down
60 of them are from Service Control Manager and say The TDKLIB service failed to start due to the following error: The system cannot find the file specified.
One of them says {Registry Hive Recovered} Registry hive (file): '\??\C:\Users\Default\NTUSER.DAT' was corrupted and it has been recovered. Some data might have been lost.
16 are warnings that various processors in Group 0 are being limited by system firmware.
12 say the certificate for local system with thumbprint <bunch of hex numbers> is about to expire or already expired.
108 are warnings for failure to load the driver \Driver\WUDFRd for various devices
16 are application errors
One is for the computer rebooting from a "bug check"
15 are for name resolutions timing out after none of the configured DNS servers responded.
10 are for SecureBoot being disabled.
14 for services terminating unexpectedly
15 are for WLAN Extensibility Module has stopped
61 are for applications not being able to be restarted because the application SID does not match Conductor SID
12 are for activation of CLSID timing out waiting for the service wuauserv to stop
So, I'll call them on Monday and open. a. new. case (#5?) - but really 7. And get A NEW BOX.
I'll keep you updated!

Unable to access gateway and DNS via VPN (L2TP) with Snow Leopard Server

Summary:
After rebooting my VPN server, i am able to establish a VPN (L2TP) connection from outside my private network. I am able to connect (ping, SSH, …) the gateway only until the first client disconnects. Then i can perfectly access all the other computers of the private network, but i cannot access the private IP address of the gateway.
Additionally, during my first VPN connection, my DNS server, which is on the same server, is not working properly with VPN. I can access it with the public IP address of my gateway. I can access it from inside my private network. A port scan indicates me that the port 53 is open, but a dig returns me a timeout.
Configuration:
Cluster of 19 Xserve3.1 - Snow Leopard Server 10.6.2
Private network 192.168.1.0/255.255.255.0 -> domain name: cluster
-> 1 controller, which act as a gateway for the cluster private network, with the following services activated:
DHCP, DNS, firewall (allowing all incoming traffic for each groups for test purposes), NAT, VPN, OpenDirectory, web, software update, AFP, NFS and Xgrid controller.
en0: fixed public IP address -> controller.example.com
en1: 192.168.1.254 -> controller.cluster
-> 18 agents with AFP and Xgrid agent activated:
en1: 192.168.1.x -> nodex.cluster with x between 1 and 18
VPN (L2TP) server distributes IP addresses between 192.168.1.201 and 192.168.1.210 (-> vpn1.cluster to vpn10.cluster). Client informations contain the private network DNS server informations (192.168.1.254, search domain: cluster).
_*Detailed problem description:*_
After rebooting the Xserve, my VPN server works fine except for the DNS. My client receives the correct informations:
Configure IPv4: Using PPP
IPv4 address: 192.168.1.201
Subnet Mask:
Router: 192.168.1.254
DNS: 192.168.1.254
Search domain: cluster
From my VPN client, i can ping all the Xserve of my cluster (192.168.1.1 to 18 and 192.168.1.254). If i have a look in Server Admin > Settings > Network, i have three interfaces listed: en0, en1 and ppp0 of family IPv4 with address 192.168.1.254 and DNS name controller.cluster.
The DNS server returns me timeouts when i try to do a dig from my VPN client even if i am able to access it directly from a computer inside or outside my private network.
After i disconnect, i can see in Server Admin that the IP address of my ppp0 interface has switch to my public IP address.
Then i can always establish a VPN (L2TP) connection, but the client receives the following informations:
Configure IPv4: Using PPP
IPv4 address: 192.168.1.202
Subnet Mask:
Router: (Public IP address of my VPN server)
DNS: 192.168.1.254
Search domain: cluster
From my VPN client, i can access all the other computers of my network (192.168.1.1 to 192.168.1.18) but when i ping my gateway (192.168.1.254), it returns me timeouts.
I have two "lazy" solutions to this problem: 1) Configure VPN and DNS servers on two differents Xserve, 2) Put the public IP address of my gateway as DNS server address, but none of these solutions are acceptable for me…
Any help is welcome!!!

I would suggest taking a look at:
server admin:vpn:settings:client information:network route definitions.
as I understand your setup it should be something like
192.168.1.0 255.255.255.0 private.
at least as a start. I just got done troubleshooting a similar issue but via two subnets:

Oracle RAC 11g on Windows 2008 64 bit - blue screen error on both nodes

Hi Everyone,
I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull and crs_state -t shows all services in two nodes are online.
When executed a select query with 100 sessions( For performance evaluation using Transaction generator ) ,the machine got crashed and blue screen is appeared on two nodes. I restrated the machines and and starts the same evaluation ,bt the same bug is repeating.
Can anyone suggest a solution to solve this issue? Is our hardware is not sufficient ? Shall we need to perform any
specific settings in Oracle RAC setup for performance evaluations?
Is our settings for load balancing is not enough? ( We added "Load Balancing= On" on tnsnames.ora on client for load
balancing)
The following machine configuration is used for Oracle RAC setup
Intel Core 2 Duo 2.66 GHz,
Ram :4GB.
OS : windows 2008 Server 64 Bit
Oracle RAC 11g , Clusterware 11g R2 , ASM with 5 raw disk ( 1- votting disk ,1- ocr files and 3 disk files)

Can you please tell any suggesstions to solve this issue? Is our hardware is not sufficient? Or any software settings has to be done?. I tried most of hte technique ,bt the problem still exists.

Oracle RAC , Clusterware 11g R2 64 Bit.i guess you have installed/configured RAC using VMware. i guess, the problem is with your RAM size. how much disk space and RAM size you have allocated for each machine?
which documentation you have followed?

11g CRS and ASM, 10.2.0.4 database, how to set up RMAN

Hi all, I am fairly green when it comes to RAC so please bear with me. I have a Linux 2 node RAC environment. The servers are lux148 and lux149. The 2 node cluster is running 11g CRS and ASM. The database is 10.2.0.4. It had to be set up this way in order for IBM DataStage to work. The database name is fictrp0. The instances are fictrp01 (lux148) and fictrp02 (lux149). I am trying to register the database with an RMAN catalog. I am under the impression that I need to register the database (fictrp0) not the instances (fictrp01 and fictrp02) with the RMAN catalog. Is this correct? So I log into lux148 and set my environment so the ORACLE_SID=FICTRP0. From the command line I issue the following:
fictrp0:/u01/app/oracle> rman target / catalog rman102/[email protected]
The command returns the following:
Recovery Manager: Release 10.2.0.4.0 - Production on Wed Oct 29 14:05:50 2008
Copyright (c) 1982, 2007, Oracle. All rights reserved.
connected to target database (not started)
connected to recovery catalog database
Is this normal "connected to target database (not started)"? I was expecting to see a DBID=FICTRP0 for the target. If this is typical, how will RMAN know the ID of the database? Should I be trying to register an instance perhaps such as FICTRP01? If so do I need to register both instances (FICTRP01 and FICTRP02)?
Bottom line I am very confused on how RAC and RMAN work together. Any help would be greatly appreciated.

You no need to register the instance,You need to register only the database and database only will have DBID

Oracle RAC 11g query

Hi All,
I am new to Oracle RAC 11g, facing a issue, Request all to help.
1) What is the instance id means which we get from gv$session in Oracle RAC setup?
2) What is differnce between Session failure and node failure?
3) If session fail, then client should connect to node1(to which session previously connected) or node2?
Thanks

1) What is the instance id means which we get from gv$session in Oracle RAC setup?Instance ID is unique for each instance in clustered database.
2) What is differnce between Session failure and node failure?Session Failure - when the connection to an instance is lost, SESSION failover results only in the establishment of a new connection to another Oracle RAC node
Node Failure/Eviction - we can say hardware fails, the Cluster Manager reports the change in the cluster's membership to Global Resource Directory (GRD)
Resource directory which consists of both Global enqueue service & cache service
3) If session fail, then client should connect to node1(to which session previously connected) or node2?You have to configure in SERVICE.
