Newbie RAC question

I have 3 production database servers with 2 databases on each server (6 databases total). Can I set up a RAC environment with just 1 additional node/server? Meaning can I have that clustered server serve all 6 database services while transparent to the app? I hope this make sense.
Thanks.

Hi,
Yes you can clustered the 3 servers that you have and cluster all instances.
cheers

General place for newbie datamodeler questions?

With the production release of SQL Developer Data Modeler I'd assume that this forum will draw a bunch of new users. Is there a better place to ask some pretty simple, newbie like questions that won't bother the more seasoned members?
For instance, I am working in a Rails environment, which has some stringent naming conventions, one of which is that all of the primary key columns are numeric and called "id", with the foreign key linked columns called <table_name>_id. When engineering a logical model to a relational model, the added foreign key columns are all "id#". Is there a way I can define a naming rule to keep me from having to redo the relation column names?
Also, we have a standard set of columns (mostly Rails related) which appear in every table. Can I define a generation rule which automatically includes these tables?
Thanks

Thank you. I will try changing that setting.
IS there a setting which tells the relational model to automatically create pk and fk indexes? I haven't seen one, and manually setting them up is a tedious task. --sw

Newbie script question... consecutive numbers with update.

complete newbie type question... this is also my first post. ( I am using CS3)
does anyone have a script which can make it so I can add numbers into the text consecutively.
for example, if this is my text "the big fat dog sat on the very wide mat, but was then displaced by a unfriendly cat."
and I wanted to place a number 1, number 2, 3, etc at points in the text so it read, "the big fat dog1 sat on the very wide mat2, but was then displaced by a unfriendly cat3." but later wanted to add another number and have later numbers update themselves, so the text then said, "the big fat dog1 sat on the very wide mat2, but was then displaced3 by a unfriendly cat.4".
by inserting the three, the previous three became four.
Has anyone got something which might be useful in this regard.
Many thanks
Steve

i wanted to avoid footnotes as they leave a bar at the bottom of each page.
i wanted a script to do something similar to footnotes but not much further.
does anyone have just a simple script that can do what I asked?

Newbie XSan question - authenticating a computer from XSan Admin

Hello - I have a very newbie XSan question!
I have 2 computers that connect to an XSan. 1 I am having no problems with. The other I am unable to connect with.
When I look in XSan Admin the 2nd computer (the one that is not working) is not authenticated.
So I click on it and choose Authenticate. I enter what I know is an Admin username and password for the computer I am attempting to connect. The dot next to the computers IP turns green with 3 dots in it and then it turns gray again. It just does not connect.
What is the problem?
Is it licensing?
Thanks
Taj

You need a different license ID for each machine, plus the admin machine. Do you have that?

This Newbie Has Questions

Hi there. I am a newbie to Apple. I purchased the iBook last month and of course, when the MacBook (which had the features I wanted) came out, I rushed out and got one and I'm very pleased with my purchase - but I have a few "newbie" questions:
1) Printing on a PC based Linksys seems to be a nightmare. I can't get anything printed on the shared HP 2600N and HP1012 printers. I literally have to disconnect them from the PC and plug the USB directly to my MacBook to print. It seems like there should be a better, easier and MacFriendly way of doing this - anyone have an easy solution?
2) I'm going to purchase Windows XP so I can run my windows programs on this computer. Does anyone have any pre-installation advice?
3) I have a blackberry device that worked fine with my iBook, but does not work with my MacBook - any suggestions or is there a software compatibility patch?
4) I transferred everything from my old Mac to my new Mac with no problem. How can I migrate my contacts from Entourage to the Address Book?
5) I notice that sometimes the MacBook "stalls" or doesn't work fast in some functions...is it just me - I expect the machine to jump quickly...but sometimes I get that annoying pinwheel when opening programs.
Thanks for your help!

The problem is probably a driver issue.

You may need to use a third-party driver such as the HPIJS drivers or the Gimp-Print drivers, but this is not the case with all printers.
2) I'm going to purchase Windows XP so I can run my
windows programs on this computer. Does anyone have
any pre-installation advice?
Ensure you get a full version (not an upgrade version) and it comes with XP SP2 already.
Do not install Boot Camp on a critical machine and make regular backups of your data, this is beta software and there are bugs and issues.

Newbie wireless question (slightly off-topic)

I didn't want to post this here as it's not entirely an Airport-specific question. I posted this to the iBook forums, but nobody there has answered so my apologies if this is not welcome here. (Any moderators can remove it if that's the case.)
I've been using computers extensively for over a decade, but I'm a total newbie to wifi. I just set up a wireless network in my house and would appreciate some advice/feedback.
My main concerns are whether or not my network is reasonably secure. I know there is no such thing as perfect security, but I don't know if what I've done is good enough or not.
I don't have an Airport base station, but I do have a D-Link Airplus G and an Airport card in my iBook. I have WEP set up on the router and I have enabled MAC filtering, listing only my desktop and my iBook, excluding all others from the network.
I'm fairly certain that nobody in my neighborhood is going to get into my machines this way or be able to sniff my network data stream, but am I right in assuming that nobody can "piggyback" on my Internet connection too? Presumably, if everyone but my own machines are MAC-filtered and kept out, then the Internet connection is also protected. Is that how it works?

WEP and MAC filtering are better than nothing, but you can do better. These are my suggestions:
1. Use WPA with a pre-shared key (PSK) and TKIP encryption on your Netgear router, along with an alphanumeric passphrase of at least eight characters not found in any dictionary. The equivalent setting on your Mac is "WPA Personal". Unlike WEP security (which an expert can crack in under half an hour), WPA security is currently unhackable by any practical means as long as you use a non-dictionary passphrase. One last point - WPA security requires all your wireless Macs to be running MacOS 10.3 or newer.
2. MAC filtering is (these days) essentially useless as a wireless security method. Using "packet sniffing" of traffic on your wireless network to find out what MAC addresses are used by computers on your network, and a PC that allows its MAC address to be cloned so that it is identical to the MAC address of one your own wireless computers (which is possible with most PC wireless network adapters) even an amateur hacker can defeat MAC address filtering in minutes.
By the way - I don't think your posted message here is off topic. In my opinion, the Airport discussion forums are the best place to post any questions related to usage of wireless networks. Questions of this nature are virtually never specific to any Mac model.

Oracle RAC Question

Question about oracle rac. lets say we have a 3 node RAC database and our tnsnames.ora file is configured to point to node 1. If an application is connected to the database using the database connection information that is on the tnsnames.ora file (pointing to node1), and node 1 is down, how does the application know to point to node 2 or node 3 to connect to the database?

If you didn't configure node2 and node3 as failover nodes, only the currently connected sessions would failover by the other nodes.
New connections are no longer possible.

Newbie saving question in Illustrator

I know this is a newbie question. I designed a logo in Illustrator. Is there a way to save just the logo for exporting into other applications (ie Pagemaker or Photoshop) without having the white artboard?
Thanks
Brad

I don't know Pagemaker but with Photoshop I simply select all, copy and then paste in Photoshop - transparency will be maintained. If you paste as a Smart Object you retain the ability to edit the Illustrator artwork in Illustrator and update the PS file.

RAC Questions

Hello,
I have couple of questions
1) In a two node RAC, if we lost the interconnect between two nodes which one will be part of cluster or which node is evicted? (I think the one with lowest node number will survive, but i am not sure what the "lowest node number" mean)
2) At any given point of time how do we know which node is a master node in a multiple node RAC?
3) I have regular backups of my OCR and VOTEDISKS, but unfortunately if we loose current copies and backup copies of both, how to recover from this kind of scenario? Do we need to rebuild the cluster or do we any other alternative?
4) If my OCR disk is on ASM, if i want to manually take a backup using dd command, is it possible ? as dd is at OS level but as it doesn't undersatnd the ASM path name in "if", how do we do this?
Thanks

(I think the one with lowest node number will survive, but i am not sure what the "lowest node number" mean)The node which is added in the first place to the cluster, which means node #1.
2) At any given point of time how do we know which node is a master node in a multiple node RAC?You can use this command grep -i "master node" ocssd.log to find the master node. Another common assumption is to assume that the node that contains the OCR backup is the master node but its not always true.
3) I have regular backups of my OCR and VOTEDISKS, but unfortunately if we loose current copies and backup copies of both, how to recover from this kind of scenario? Do we need to rebuild the cluster or do we any other alternative?If you have lost OCR and have no backup, there is still a way to recover it and its on MOS. I don't have the note with me handy so you got to search for it. I shall see if I can find it and update the reply later.
Update: Have a look at this MOS note 399482.1.
4) If my OCR disk is on ASM, if i want to manually take a backup using dd command, is it possible ? as dd is at OS level but as it doesn't undersatnd the ASM path name in "if", how do we do this?OCR backup by DD? Are you sure you talking about the right thing? The only option where DD was used in the previous versions was for Voting Disk. I never recall that this method was used for OCR as its always auto backed up. The answer to your question in the context of Voting disk is that you can't do it and Oracle has very clearly mentioned attempting to do so would end up in the corruption of the Voting Disk and if you attempt to do so for OCR, I believe the answer remains the same.

Newbie Grid Questions - Windows 2008 v11gr2

Hi all
As stated I am completely new to Oracle and have managed to do an single instance install and am now attempting a Grid and then RAC install.
I have created 2 VMs and 5 disks. During the Grid install I stamped the disks so that they could be used for ASM and put them all in a disk group called Data. I selected External redundancy.
In the previous documentation I have seen that during the Grid install you select where to put your voting files and OCR files but this never happened for me, is this correct? Also how can I check I have clusterware installed correctly? The documentation says that the verification utility runs automatically and I think this happened as the Grid install completed successfully.
One concept I am having troubles with is if the clusterware is installed as part of Grid then why do we need RAC?
My questions are probably very general and cover a lot, but any help in the right direction would be appreciated.
Thanks

Hi,
In the previous documentation I have seen that during the Grid install you select where to put your voting files and OCR files but this never happened for me, is this correct?If you selected to Oracle ASM as the storage option for the OCR and voting disk files, then the Oracle Automatic Storage Management Configuration Assistant (ASMCA) configures Oracle ASM as part of the installation process.
If you did not select Oracle ASM as the storage option for the Oracle Clusterware files, then you must start ASMCA manually after installation to configure Oracle ASM.
There are two ways of storing the shared Oracle Clusterware files:
Oracle ASM: You can install Oracle Clusterware files (OCR and voting disks) in Oracle ASM disk groups.
OCFS for Windows: OCFS for Windows is the only other supported cluster file system that you can use to storage of Oracle Clusterware and Oracle RAC files on Microsoft Windows platforms.
Starting with Oracle Database 11g release 2 (11.2) and Oracle RAC 11g release 2 (11.2), using DBCA or OUI to store Oracle Clusterware or Oracle Database files on raw devices is not supported.
Also how can I check I have clusterware installed correctly? The documentation says that the verification utility runs automatically and I think this happened as the Grid install completed successfully.You can use Cluster Verification Utility.
The cluvfy stage -post crsinst command to check the specified nodes after installing Oracle Clusterware.
http://download.oracle.com/docs/cd/E11882_01/rac.112/e16794/cvu.htm
One concept I am having troubles with is if the clusterware is installed as part of Grid then why do we need RAC?I do not understand what you meant with GRID is grid infrastructure (software Oracle ) or grid computing (concept).
If is concept check this..

RAC question

Hi,
Version 11g
I have RAC 11gR2 on two nodes with ASM.
The DB name is : cstrprd
On the first machine the asm instance is : +ASM1 and the instance name is cstrprd1
On the second machine the asm instance is : +ASM2 and the instance name is cstrprd2
The question is regarding /etc/oratab
# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# Multiple entries with the same $ORACLE_SID are not allowed.
+ASM2:/u01/app/11.2.0/grid:N # line added by Agent
cstrprd:/u01/app/oracle/product/11.2.0/CSTOREPRD11gR2:N # line added by AgentThe last two lines created by root.sh
I would like to know if its OK that the name of the DATABASE (cstrprd) was written to the /etc/oratab as you can see above ,
and not the name of the INSTANCE as follow
cstrprd2:/u01/app/oracle/product/11.2.0/CSTOREPRD11gR2:N Thanks

Hi,
if your entry
cstrprd:/u01/app/oracle/product/11.2.0/CSTOREPRD11gR2:Y like this then if node reboots it will start the entire database including 2 instances (cstrprd1,cstrprd2)
suppose if your entry
cstrprd1 :/u01/app/oracle/product/11.2.0/CSTOREPRD11gR2:Y like this then , if node reboots only cstrprd1 instance will come up on first node . vice versa...
Note : suppose if u use instance name in oratab , it will be helpful when using . oraenv .
. oraenv
ORACLE_SID = [oracle] ? cstrprd1
just give instance name , it will take the ORACLE_HOME automatically otherwise u have to give ORACLE_HOME also manually ...

Dumb newbie hardware question! :)

Hi folks,
I'm new to the world of the blackberry and am just about to take the plunge with an unlocked sim-free BB Bold to use in the UK on Vodafone. I have read about the software differences between BIS and BES and would be going for a BIS set-up. My dumb newbie question is does the hardware come in BES and BIS versions or not?
Many thanks in advance and feel free to mock my foolishness
Solved!
Go to Solution.

hello, about BIS and BES it's explained on the website but it's clear that if someone sums it up for you it will be easier...
so BES is a type of contract between a company and Blackberry. The company IT buy computers, put Blackberry servers, and buy a fleet of Blackberry Devices for the people in the company to use them and get email through the Blackberry servers.
BIS is a type of contract between a common person and a carrier. The consumer goes to the carrier, and buys a Blackberry device, and a BIS plan that will enable him/her to :
phone/sms/mms
receive emails that have been configured on the BIS site
do data things if you subscribe to (like browse the web)
You can buy a Blackberry from a carrier that has a deal with RIM (the company that sells Blackberries). Or you can buy a blackberry alone, and then go and contact a carrier that has a deal with RIM.
phone/sms/mms
receive emails that have been configured on the BIS site

NEWBIE SOA Question:Appl Development for SOA

This question may have been answered elsewhere; if so, my apologies.
As a newbie to SOA, I am trying to wrap my head around the question of how app. development for SOA differs from traditional models. For example, non-SOA environments there are few external considerations when coding a process,
but in SOA environments, I understand everything is a service.
Can someone provide a few code snippets as to how they would look in each environment?
I have read through several documents on SOA and have done the SOA tutorial, etc. but I have yet to see a side-by-side comparison of application code in SOA and non-SOA environments.
How would an architect plan the translation and mapping of business objectives and functional requirements into a technical solution for SOA, architecting the SOA solution ?
I would really appreciate any pointers (links to articles, etc.) in this direction. Thank you.
Gordon

Hello Gordon,
SOA (Service Oriented Architecture) - as the name indicates, it's design is based on services. SOA is another integration technique which is used for small scale integration. SOA is an approach to have software resources in an enterprise available and discoverable on network as well defined services. Each service would achieve a predefined business objective and perform discrete units of work. The services are independent and do not depend on the context or state of the other services. They work within distributed systems architecture.
Few links which may help you in understanding SOA and it's design patterns -

Newb HD questions...?

I'm a newb to HD and we've just got funding for a HD camera. The boss bought a Panasonic AG-HMC150P.
The question is about recording mode, in "p" or "i". Currently it is set for 1080/60i, its top setting. But it has a 1080/30p too.
Our products will be made to view on a TV screen ntsc, and a computer screen.
Is the "i" setting the best for us? ie: is there any advantage in us using the 30p setting?
Also, I have FCP6 and a colleague has FCP5 on a less powerful machine.
Whats the best way to hand him newly captured HD footage? Is it to render it out using H264 on my machine before passing it over?
We are hoping funding for software upgrade/machine will come soon for him.

Well, the short answer is "i" (interlaced) is only for display on older CRT "tube" televisions. "p" (progressive) is for display on computers and flat screen televisions. Typically you should try to stay progressive these days. 60i can be useful if you are going to slow-mo any shoots.
Do NOT convert your files to H.264 to send to another edit. H.264 is not a good codec for editing, use it for distribution of edited material only.
For sharing with FCP5 on a slower computer, consider using DVCProHD.

Newbie audio question--help please...

I recently recorded/captured video from Canon HV30 and unfortunately found that only Left audio channel was recorded..Right channel in non-existant. How do I duplicate the audio track from Left to Right so that both tracks are played in sync?
I appreciate your help on this newbie question!

When the left channel is filled you use the Fill Left effect
The Fill Left effect duplicates the left channel information of the audio clip and places it in the right channel, discarding the original clip’s right channel information.
Instead of putting the effect on each clip use the Audio Mixer.
