Change DBID on RAC System

There is alot of documentation on changing the DBID of a cloned database on non-rac databases. What do you think will be the differences if I try it on a RAC 10g system?

gotta take 1 of the nodes out of cluster mode first.
Backup the database
Shutdown both instances cleanly
make 1 of the instances cluster_Datbase= false
Startup that instance mount onlu
then run nid utility
shutdown
startup mount
alter database open resetlogs
cluster_database=true for that instance
shutdown the current instance and start all isntances cleanly with rac commands if possible

Problem of Copying the Original VM to 2nd VM in Oracle 11gR2 RAC system

Folks,
Hello. I have been installing Oracle Database 11gR2 RAC system using 2 nodes that are 2 Virtual Machines (rac1 and rac2) on the top of VMPLayer 3.
I follow the tutorial http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html to do.
The original Virtual Machine rac1 has run correctly. I configure rac1 network (eth0 and eth1) by opening VM rac1 and using command "[root@rac1\] #neat" as root user to invoke the network configuration.
For the second Virtual Machine rac2, I simply copy all files in "C:\VM\rac1" into "C:\VM\rac2". Then I have done the following:
1) In the directory "C:\VM\rac2", rename "rac1.vmx" to "rac2.vmx".
2) Change display name from "rac1" to "rac2" in the file "rac2.vmx".
The next thing to do for rac2 is to open the Virtual Machine rac2 and configure its network (eth0 and eth1) by using the command "[root@rac2\]#neat" as root user.
But by this step, I don't understand how to open the Virtual Machine rac2 so that can configure its network (eth0 and eth1).
Can any folk tell me how to open the VM rac2 to configure its network by this step ?
Thanks.

Folks,
Hello. Thanks a lot for replying.
The public IP for eth0 and private IP for eth1 in the file "/etc/hosts" are as follows:
rac1 eth0 192.168.138.35 eth1 192.168.137.35
rac2 eth0 192.168.138.36 eth1 192.168.137.36
In rac1, I have added 2 entries in /etc/hosts as following:
#VIP for eth0
192.168.138.130 rac1-vip.localdomain rac1-genetic-vip
192.168.138.131 rac2-vip.localdomain rac2-cellar-vip
Then I execute the command: [root@rac1 /]# ping rac2
Output:
PING rac2.localdomain (192.168.138.36) 56(84) bytes of data
From rac1.localdomain (192.168.138.35) icmp_seq=1
Destination Host Unreachable
In rac2, I try to add the above 2 entries in /etc/hosts. But cannot save it. The following error message comes up:
"E45: readonly option is set (add ! to override)".
My questions are:
First, do I need to add VIP in the file "/etc/hosts" for both rac1 and rac2 ?
Second, why rac1 still cannot reach rac2 after add VIP in /etc/hosts for rac1 ?
Third, why the file "/etc/hosts" in rac2 is read-only ? How to change it to be editable ?
Thanks.

How to open the second VM in Oracle 11gR2 2-nodes RAC system ?

Hi,
But by this step, I don't understand how to open the Virtual Machine rac2 so that can configure its network (eth0 and eth1)."rac2" is a new virtual machine after you copied and changed the display name and you need to add this in the vmware enventory (I am talking about vmware server and vmware player should have the same way as it is supposed to run multiple vritual machines on your PC). Then it will be visible it to you. Now start this new machine and edit the network configuration.

Disable SSH root login in RAC system

Hi Alll,
We have a oracle 11.2.7 RAC in Linux. As statement, SA will disable ssh root log and Nagios will monitor each nodes in RAC system.
As I know, Nagios only apply DH key for SSH. But Oracle RAC apply two type of SSH key for ssh_equivelancy in Oracle CRS.
Dees any experts have experience for oracle RAC and database when disable root SSH log in Linux system?
Thanks very much!

Security is not based on the number of keys one needs - but on the quality of the locks.Partially agree. But just like in real world one lock is not enough even superb. Why cars have imobilisers, defendlocks etc.? Why there is fence in front of some shop's door? It's very common to have two locks on front door. It's much harder (at least it takes much time) to break two locks than break just one. And the time matters. Back to IT security. Disabled root account is one of best practices and is reasonable because you can't 100% assure that your administrator is using strong password everytime. He might just forgot to change password after installation. He might set weak password just for "temporary" reason. You can of course force the password complexity but of course one you have the system installed.
So can passwords. Deep packet inspection can occur unknowingly. Perhaps we still talking about SSH, don't we?
The user may be targeted using social engineering, instead of targeting the actual computer system.It's much harder to get two passwords than just one even by using social engineering.
The question is whether such a server is exposed to an unsecured or public network. And one would manage the risks differently on such a server than one for example in a private network, protected by a reverse proxy in the DMZ, that in turn provides access from a public network.OK, so we've got another locks here ;-)
So if that user is compromised, so can root as that user can gain root access. I do not see this as better security. It is merely obfuscating security.Which user acccount? Do you know name of that account? Because I know the name of your's. ;-) So you need to find correct account name, get password for that account and also get the password for root account whilst I need to get password for root account only.
Yes, partially agree with "obfuscation security" term. But in fact this is not for first time when obfuscation is used in security and neither for last time.
But you can't consider "PermitRootLogin no" and "wheel" group as an obfuscation.
Using encryption keys (public & private) is one answer to having to share and keep secrets. No, this is also not 100% safe, but I prefer it over having to know, remember and on occasion, share secrets (passwords).How well is your local machine secured? Are you using strong password? Do have all accounts strong password on your local machine? Is your local machine up to date for known sec. bugs (I don't mean zero days)? Is your local machine in separated VLAN or anybody from LAN can access your machine? Because if there are at least two "No" answers then how much time it will take for some skilled part-time worker (in your company) to break into your computer, steal the keys or even worse use your local machine to access the server?
Don't get me wrong. I am not against encryption keys. Of course I am using it but in combination with other security restrictions which come from "best practices". And to disable direct root access is one of those practices. Even NSA (and other security institutions) suggest to do that (see page #37): www.nsa.gov/ia/_files/os/redhat/rhel5-guide-i731.pdf Also security auditors check for disabled direct access to privileged accounts.
I understand this as good enough proof that disabling of direct access to privileged accounts rises security.
Another good reason is right here:
Install
In other words, if any user has possibility to login as root, he uses "root" as default account which is another well known bad practice.

Change DBID

Hi,
on 11g R2 I have some manually copied databases. I back up them in nocatalog mode. Then in controlfiles.
I heard about DBID and then I looked at documentation that says :
Because Recovery Manager (RMAN) distinguishes databases by DBID, you could not register a seed database and a manually copied database together in the same RMAN repository. Then can we say DBID is not a concern/problem for me because I do not have a RMAN repository and it is not necessary to change DBID of copied databases ?
Thank you.

Thank you.it depends.
answer depends upon what you are going to restore where.
DBID must be unique on single system.

Ho to change the old Logical System in the new Client?

Hi All,
after a Client copy, I've to change the old Logical System in all the relevant SAP tables in the new client.
In the Co tables too, such as CSKS.
Could anyone tell me hoq to do it?
Thanks
G.Rossi

Hi,
So the only solution would be to rename the SID of one portal.-> Yes,Rename the SID of on portal
Can this be done ? -> Yes,It can be done
How is it done ? -> Use Export/Import method.Export the database of one SID. Import the same with different SID.
Thanks and Regards,

Is it possible to change settings in "Help System info"?

Is it possible to change Photoshop settings by clicking on Help and then System info? Since there is the possibility to type and the OK-button, I just started wondering.

All Help > System Info does is to report your system specifications so you can copy and paste them in the forums for troubleshooting purposes.
You can choose what to highlight and copy, but it does not change anything in your system like editing a configuration file would.

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

Hi Experts,
we use 4 nodes RAC (11.0.1) with 10.2.0. 4 database in red hat5.0
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!
JIm

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 ?

It is true that the only way to sync your Mac with iCloud is to upgrad. You need to be running OS X Lion 10.7.2 or higher in order to sync your Mac with iCloud. At this point, you can upgrade directly to OS X Mountain Lion from the version of OS X you are now running (10.6.8). You can purchase and download the Mountain Lion upgrade from the Mac App Store for $19.99. After upgrading you will see iCloud in System Preferences. This guide explains how to sync your Mac with iCloud after upgrading: http://www.apple.com/icloud/setup/mac.html.
Once all your devices are signed into the same iCloud account and you have turned on your iCloud data syncing, you will be able to keep them all in sync using iCloud. You will still have to sync with iTunes to manage your iTunes media such as music, movies, podcasts, etc. You will have the option to either continue backing up automatically with your computer when you sync with iTunes, or to back up your iOS devices automatically to iCloud every 24 hours (as long as they are connected to wifi and your chargers).

InfoCube Error Message: Choose a change request with target system BWQ

I have a problem when I want to edit an InfoCube created by other developer. The error message received is as follow:
"<b>Choose a change request with target system BWQ</b>".
When I click on the Documentation (F9) button, the detailed message is:
"Message no. TK511
Diagnosis
The selected change request BWDK901086 has target system .
However, the objects you edit can only be recorded in change requests with the target system BWQ.
The correct target system is determined from the package and transport layer to which the object concerned belongs.
System response
The selected change request BWDK901086 is not used to record the objects.
Procedure
Either choose a different change request or change the target system of the change request BWDK901086.
From the prompt window for change requests, you can display all requests you can use by choosing Own requests.
Alternatively, you can create a new request by choosing Create request.
For more information, see the SAP Library under BC - Basis Components -> Change and Transport System ."
Can someone helps me to solve this problem?
Thanks!

hi Fullham,
try se09/10 and find request BWDK901086 (use binocular icon) or se03. then double click that request, go to tab 'properties', hope you will see 'Target System' system there, click 'edit'/pencil icon and change it to BWQ.
you may need to change the owner (which may not authorized), ask basis help if necessary.
hope this helps

How can I import a change request to a system which is not in the domain

how can I import a change request into a system which is not part of the transport domain?

Hi,
You can transport any requests to any systems even though they are not in the transport domain.
1) Move the corresponding data & cofiles( in /usr/sap/trans/data & /usr/sap/trans/cofiles directories) to the same location in the target system.
2)Add the request to the queue from STMS ->Import Queue ->Extras ->Other Requests - >Add.
3)The execute the transport as usual.
