RAC + dataguard architecture/setup metalink notes

Looking for RAC & dataguard configuration for one db ...

Hi,
I think it is rather worth to look around on the [Oracle Maximum Availability Architecture site|http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm] for whitepapers than checking the Metalink (Well, at least I like MAA much better the Metalink)
Hope this helps.

Production site RAC redundant architecture deployment

We need the advise from Oracle Experts regarding our production site RAC redundant architecture deployment
For some business constraint, We have only 2-NIC Available for configure the redundant RAC Deployment
So are planed to bonding the available 2-NIC and after NIC bonding we got only one bonding interface of 1gbps speed.
We have configure the public and private ip address in that available single bonding interface.
network configuration
#bond0 (public network)
10.106.1.246 rac1
10.106.1.247 rac2
#bond0:1(vip network 10.106.1.251)
10.106.1.251 rac1-vip

10.10.0.1 rac1-priv
10.10.0.2 rac2-priv
#bond0:2(scan ip)

Can you please conform that above architecture will support in production site?
what is the advantages and disadvantages with above architecture in production site?
Can you please suggest the right way of deployment the redundant RAC deployment in production site?

This is one case where I would say that you are playing a very dangerous game with your production system. You asked for Expert opinions and you have been informed that this is a VERY BAD IDEA!!!! While you think that it works, don't come asking about node evictions when your bonded nics get saturated. I can say that I am an expert having installed, configured and spent time troubleshooting more than 75 clusters (2-6 nodes) on some very impressive hardware. The "big one" was 250TB on a 3 node RAC on Sun 6900's (48 dual-core x 192GB main memory with 8 NICS using SUN IPMP and 8 HBA's for SAN connectivity ). When you start having "weird" issues, Oracle will not support your configuration. You will need to fix it before they even begin troubleshooting it. Tell your manager that unless they spring for the appropriate configuration they should execute the following command: "Alter manager update Resume;" because it is not "IF" it will fail, but "WHEN" will it fail. Trust me, you and your managers have put your system in a very precarious position.

Conflicting PROCESSES values on 10g RAC+Dataguard

Hi peeps,
So i've set up a RAC+Dataguard environment for testing, and have recently encountered ORA-12518 errors; quite a few Google results suggest checking V$RESOURCE_LIMITS for any resource problems. Upon checking i noticed that the MAX_UTILIZATION for resource PROCESSES is set to 71, with CURRENT_UTILIZATION set to 70;i found this strange 'coz i specifically increased the PROCESSES parameter to 300 when i set up the db; i ran SHOW PARAMETER PROCESSES and verified it was set to 300.
Shouldn't i be getting the same values?
tia

Hello badkuk,
The max_utilization column means the greater value of this resource since last instance startup. See it on http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2050.htm#REFRN30206
Also see the description of error message at http://ora-12518.ora-code.com
I think the root cause of this error was not processes parameter.
Take a look on Metalink note ID 556428.1
*"In general ORA-12518 occurs if there is a resource problem , may be on the listener side or on the Database server. It indicates a condition where the process is not able to make any more memory allocations either due to non-availability of resource or the process has reached the 32 bit (VM Size) limit"*

Steps to sync RAC -dataguard

Hi folks,
I m having setup with 2 node RAC primary and 2 node RAC Dataguard on 10.2.0.4.0. Dataguard setup is working fine. Dataguard is setup with Standby Redo log group with managed recovery. Due to network issue network issue the transferring archives & applying on standby couldnot take place.The network issue is sorted but now the primary and standby are not in sync.
I am new with RAC and dataguard combined.Can you proivde suitable document or steps how i can manually sync both.

RAC & DataGuard (Physical Standby)

Hello all,
I'm trying to get a high level overview of how RAC & DataGuard would behave in the following configuration. I've written down my understanding of how things would work. Please correct me if I'm wrong.
1) 2 node RAC (Primary Database) with a single instance physical standby.
a) Same standby related init.ora parameters would have to configured on both primary rac nodes.
b) The redo apply service at the standby would merge the redo from the 2 threads from the primary and apply it to the standby to keep it in sync.
c) During switch over only one primary RAC instance should be up besides the standby instance.
d) During switch back again only one primary RAC instance should be up besides the standby instance.
e) During failover ofcourse both primary instances would be down which warrants the fail over.
2) 2 node RAC (Primary) with a 2 node physical standby
This where it gets complex and I'm not really sure how a,b,c,d,e would be in this scenario. Appreciate if you could shed some light on this and list what
a,b,c,d,e would look like in this scenario.
I'm assuming that only one instance in the standby RAC should be up when the standby is in RAC configuration for the redo apply to work.
Also, if there is a white paper that details step by step procedure for setting up the above 2 scenarios, please let me know. So far I was able to find only the MAA white paper but that was not very helpful. If you can prescribe a good book for RAC & DataGuard that would be great too..
Thanks for your help

>
1) 2 node RAC (Primary Database) with a single instance physical standby.
a) Same standby related init.ora parameters would have to configured on both primary rac nodes.Usually rac nodes share their spfile on a shared diskvolume or through ASM. So they have identical DG parameter anyway
b) The redo apply service at the standby would merge the redo from the 2 threads from the primary and apply it to the standby to keep it in sync.Correct
c) During switch over only one primary RAC instance should be up besides the standby instance.
Sounds logical to me
Edit: In fact during normal operation both RAC nodes are up, so during switchover they are both active too
It is the configuration that matters. As soon as the standby is becoming primary, it might be that it talks only to one RAC node for its log-apply files
d) During switch back again only one primary RAC instance should be up besides the standby instance.That single was the only one running in step c.
e) During failover ofcourse both primary instances would be down which warrants the fail over.Correct. Keep in mind that during a failover the RAC config would be deconfigured from the DG setup and has to be added back again as standby.
You might have to take a look at: http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10g_RACPrimarySingleInstancePhysicalStandby.pdf

No. RAC primary to RAC Standby would mean both nodes are up on both side. PrimNode1 send its redo logs to StandbyNode1 and the same for PrimNode2 and StandbyNode2

How do I setup Forms not to ask RAD username/password when opening a form

Good day
I have setup oid and sso and they work I can sign on to database with an oid user using sqlplus.
If I set SsoDynamicResourceCreate=true and enter the user id and password in at the popup it works correct and won’t even ask it again
What I want to know how can set portal to use a RAD/DAS without prompting for a username password.
We need to do this for all +/- 30000 users and if so how do we do it pragmatically.
I think because I don’t have much APPS experience I basically don’t know where this must be set globally
APPS is version 10.1.2

RAC + Data Guard setup

In high-level terms, if you are running a 2-node RAC and get asked to create a 2-node disaster recovery site, how would I go about doing that? (The cluster in the disaster recovery site has already been created and the Oracle 11.2.0.1 software installed).
I'm thinking generally that an RMAN clone of production to the secondary site would be an idea: but can that be done with both production nodes up? And is the best approach to clone to a single-instance and then add a second instance manually later on?
Any pointers, or tips for a 2-node data guard from a 2-node RAC setup would be appreciated, basically. I realise it's pretty vague, but I'm just scoping this out at the moment and need some general pointers.

Questions on Metalink note 392673.1 (bug 5458753)

I have a few questions on Metalink note 392673.1. This note states that if two schema have objects with similar names and these two schema issue identical statements, it is possible that the statement will run against the wrong schema's object if "a cursor gets reloaded in a certain manner".
Does anyone know any more details? What manner of reloading? Will synonyms prevent the problem? Is there a test case?
Also, the note states that it applies to versions 10.1.0.2 to 10.2.0.3, while the bug claims that it is fixed in 10.2.0.3. Is 10.2.0.3 affected or not?
Paul Muller

Hi,
It seems that bug is solved in 10.2.0.3 patchset, and interim patch for 10.2.0.2.
Anyway, if you have any question on metalink note, you might have more chance to get a valid answer by asking it into metalink forum, or send an email to the author of the note.

ITunes 10.5 Upgrade fails to Install. The Error Message is: "There is a Problem with this Windows Installer Package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."

When Upgrading on my laptop from iTunes 10.2.11 to 10.5.0 the message I get is: "There is a problem with this Windows Installer Package. Aprogram run as part of the setup did not finish as expected. Contact your support personnel or pacakge vendor.

After reading all these posts, one by one did not resolve my problem until I got the very end. Regardless of what step would resolve your problem, these are the steps I would recomment to everyone for a what seems to be a safe and fool-proof upgrade to iTunes 10.5.
1. Stand alone upgrade to the latest Quicktime version
2. Go to control panel and "change" then select repair to the following applications in the order specified by the post on Oct 27. (Notice I skipped Quicktime because it had been upgrade manually,and Bonjour did not have a "repair" option)
iTunes; Apple Software Update: Mobile Device Support; Apple Applications Support
Some of these applications may not appear if they do not apply to your configuration (no iPhone, or no iPad, or other apple devices).
Once all updated, I did not need to restart nor launch any applications, I simply went straight into the 10.5 upgrade, and where it normally got stuck, this time the installation continued for a while longer until it completed successfully.
Great work everyone who contributed! Thank you very much!

How to view all the metalink notes in a single window?

Friends,
I have metalink access...i want to view all the metalink notes in a single shot.
now i am searching the metalink notes by entering the artical id...is there any way to get all the documents in one shot ...
like how we are seeing the forum threads here...
thanks

Do you also as a librarian for an overview of all the books? :-)
Have you any idea how much information, knowledge, bug-reports, questions, patch-lists, documentation etc..etc. is on Metalink?
That would give you a list of millions of rows. And how do you want them sorted, by version, by OS, by what??

When I try to install iTunes 10.5, it says, "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." I have Windows XP and I need help.
