Suitability in Linux (newbie question)

Hi,
I'm trying to run a database that is constantly updated through a java servlet(data going in) and constantly read (no changes in data, just reading out).
I was wondering how well oracle in Linux would handle this given that there will be a few problems with write locks stopping the reading...
Many thanx in advance,
Omar

Yes, iWeb will serve your needs. You don't even need to upload them to your public folder - all you need to do is open an iWeb page and drag and drop your music files. That is just one of the many ways you can create links to your music files. You can even do a Podcast if you want and have it show up in the iTunes Store.
Good luck!

Dumb newbie question -- shell vrs linux console

This is probably a dumb newbie question, but what is the difference between the shell screen and the linux console screen? I used another system before Arch and I believe there was only the shell screen! Does it matter which one is used? Thanks -- Larry

The console is the 2D text rendering thing. The shell is Bash, just a program that handles your input and has the console as output.
If on the other hand you mean the console at startup, and you call that the console while you call xterm, etc. shells then the answer is different. It's just a matter of configuration if you automatically start X or not. A lot people use gdm or kdm to get a graphical login screen after bootup, others just type "startx" in the console when they want to start X.
You can switch to the console with Ctrl+Alt+Fn where n is a number between 1 and 6. You can switch between consoles with Alt+Fn, X is on the last console, so to go back to X do Alt+F7.

Newbie question - cloning to a new server

Hi all,
I am very new to the EBS world, so please forgive the "newbie" question. We are running 12.0.4, and we have approximately 12 different environments. We probably do 3 to 4 clones a week, generally from production to one of the existing environments.
However, we now have a couple brand new Linux servers, and we want to set them up as a new environment to clone to (one will be apps server, one will be DB server). I am looking at some of the Metalink documents on how to do this. But my basic question is this - do I first have to do a basic EBS installation onto these servers, before I will be able to clone an environment over to them?
Thanks!!

Newbie question - cloning to a new server
Re: Newbie question - cloning to a new server

Total Newbie Question ... Sorry :-(

I know it's a windows thing, and I am now converted to Mac but I gotta know this because it's doing my head in. It's a complete stupid green gilled newbie question.
When installing new programs on a Mac can you create shortcuts to the programs on the Dock? I did what I THOUGHT it would be, i.e I made an Alias and stuck it in the dock, but on rebooting my Mac later on, in place of the shortcuts where 3 question marks which when clicked on did absolutely nothing???
Help?

You aren't installing something from a dmg file are you? The dmg is a disk image – kind of a virtual CD. So when you double click the dmg and then get the little disk/hardrive/custom icon on your desktop that is the same as if you had mounted a CD. You then need to drag the application off of that "CD" into your application folder. Then it is truly installed.
You can then "eject" the icon your your desktop. This is what happens when you shutdown and without remounting the image your dock shortcut can't find the original.
Just a thought.

How to install j2re on Linux (newbie, non-developer)

Forgive me for this stupid newbie question, but I'd like to know where to put my j2re package. I downloaded the .bin file, and extracted it into the folder where I downloaded it. Does it just stay there? Is it installed? I hope not, because it's in my tmp directory.
I'm not a developer (obviously); I just want to run Open Office, which requires JRE, but gives no clue how to install it.

Newbie Question about FM 8 and Acrobat Pro 9

Hello:
I have some dcouments that I've written in FM v8.0p277. I print them to PDF so that I can have a copy to include on a CD and I also print some hard copies.
My newbie question is whether there is a way to create a PDF for hard copy where I mainitain the colors in photos and figures but that the text that is hyperlinked doesn't appear as blue. I want to keep the links live within the soft copy. Is there something I can change within Frame or with Acrobat?
TIA,
Kimberly

Kimberly,
How comes the text is blue in the first place? I guess the cross-reference formats use some character format which makes them blue? There are many options:
Temporarily change the color definition for the color used in the cross-reference format to black.
Temporarily change the character format to not use that color.
Temporarily change the cross-reference definition to not used that character format.
Whichever method you choose, I would create a separate document with the changed format setting and import those format into your book, create the PDF and then import the same format from the official template.

Domain name settings - Newbie question

Sorry for a newbie question!
I am already pointing a domain name to web hosting for email account. Now, I need an application server to run ERP software and Oracle, and installing Solaris and Oracle need a domain name.
If I point my domain name to the server, how do I receive emails from web hosting???
Install an email server to the application server instead? What can I do if I want the same domain name? Any option?

Setting up a mailserver and making sure it doesn't suddenly turn into a spambox is not something you do with the use of a few commands. I suggest to dive into the Solaris admin guide on docs.sun.com and read up on e-mail and network services.
If that is asking too much of your time you'll be better off getting your ISP to handle all this for you.

Your questions are completely off-topic for the forum.
These SunOS forums are for questions on "how do I install my OS"
You particular question is in the "how can I install Solaris while using the CD drive" forum.
So, if you had a question on how to edit the /etc/inet/hosts file to establish a FQDN on the computer, then it might be appropriate for the forum.
Unfortunately, I don't have a clue on where to redirect you, except perhaps to the Sun Java Enterprise System suite of applications?

Newbie Question: How much computer do I need?

Newbie Question:
I would like to use MainStage 3 in a live performance environment to play bars, parties, etc. I'm not looping, using it to playback recordings, processing outboard equipment or vocal processing. I want to stop carrying Rolands, Nords, Korgs, etc and get to a controller and a rack with a Mac Mini in it.
I tested a download of Mainstage 3 on my home Mac Mini (late 2012, 3.5 Ghz i5, 4GB RAM, 500GB drive) and it seemed to run fairly well. $30 well invested so I trekked forward... I purchased a Mac Mini (late 2009, 2.52GHz Core 2 Duo, 6GB RAM, 128GB SSD) for $200. I started to do more elaborate keyboard setups to see how the CPU would hold up. It typically runs from 30% to 50% of capacity (CPU and Memory) It actually boots and runs better than the i5. I hear the occasion gitch, but it actually seems to be getting better in time (or I'm rock and roll deaf.
I got a rack, an Airport Express, a Radial USB interface and a Nektar Panorama P6. It's starting to get expensive, but I'm emboldened by the actual quality for the sound and the flexibility of arranging for live performance. What used to take me two and three keyboards to play, I can now fit on one performance patch.
OK, now the question... am I at the limits of this little Core 2 Duo? Should I upgrade the i5 with more RAM and a bigger SSD and use that? Should I get a new(er) i7 and bite the $1,500 bullet for the additional RAM and SSD?
I see that most of you are running pretty nice Macbook Pros with i7 and lots of everything. My needs are modest; am I OK?
BTW, I want to run a Mac Mini in a box because I don't want to carry a laptop out in the open. If I was doing bigger shows I wouldn't care but I play some rowdy bars and constantly have folks hanging off me while I'm playing. It's fun, but hard on gear. If you can't drop it or dip it in beer, it won't last long where I work.

Rule of thumb: newer and faster is better. But, depending the complexity of your needs you may be OK with an older Mac. Some glitches that happen in a live performance are due to loss of communication with USB or Firewire inputs, so make sure they're secure. I recently upgraded from a 2010 Mac Mini 2.6 dual core with 16 GB RAM, which was used live for nearly four years, to the latest Mac Mini 3.0 i7 with 16 GB RAM and a 500 GB SSD. I was getting an occasional stuck note with the older one. The new one is rock solid. Some of my patches may have up to a dozen channel strips mapped to three keyboards. The Mini is mounted in a rack next to a MOTU Ultralite Hybrid. It is a good idea to map a panic button on your keyboard to controller # 123(all notes off). Also, you might want to invest in a battery backup power supply(APC, Cyberpower, etc.-$40-$60) to protect your Mac against power loss, which can damage you hard drive.

Multiple version of JRE in company..How to manage? (newbie question)

Greetings..this is a newbie question
We have 48 versions of JRE running in on XP IE6 in our company.
Some version beat up other JAVA applications.
It's a mess.
How can anyone manage this many versions?
Can we consolidate down to a few versions?
I saw some posts on changing the JRE dynamically or perhaps using a wrapper with a product from "sourceforge".
Are these viable?
Thanks in advance

It's a mess.can you elaborate on how some versions "beat up" other apps?
How can anyone manage this many versions?you don't, each computer should periodically upgrade (IMO) but you shouldn't care. if you do, tell your users to load the latest version
Can we consolidate down to a few versions?sure

Newbie question - XML version, searching by artist

Probably quite a common problems - apologies for newbie questions.
I've changed the URL of my MP3s in my XML to a new location and refreshed my feed. Is there a way of seeing what version of the XML iTunes is using? (it takes around 24 housr to refresh, right?)
Also, when I'm searching for my podcast by author it's not coming up (<channel><itunes:author>) - is there a reason for this or a way to get it to show up when people search for the artist, other than doubling it in the title? (This works by the way, but I'd prefer not to!)
Thanks.

you can do it in just one loop, going through all the image
tags in index_content and for each tag fill the values of all four
arrays
for (i...) {
get the appropriate child of index_content
first_array[ i ] = value of first tag
second_array[ i ] = value of second tag
no need for multiple loops.
flash has functionality for xml files, but it helps to write

Newbie question: ""dynamic"" casting

Hello all,
 
I have a quite newbie question. I have this class hierarcy:
 
A
|_A1
|_A2
|_A3
|_A4
|_A5
|_.....
 
in some part of my code I have this:
 
if (object1 instanceof A){
if (object1 instanceof A1) {A1 object2 = (A1) e;}
 if (object1 instanceof A2) {A2 object2 = (A2) e;}
 if (object1 instanceof A3) {A3 object2 = (A3) e;}
 if (object1 instanceof A4) {A4 object2 = (A4) e;}
 if (object1 instanceof A5) {A5 object2 = (A5) e;}
object2.callMethod();
 
Is there any way to do this type of casting just in one line? I mean, I just want to cast object1 to the class it is instanceof. If it is instance of A1, I want to be casted to A1, if it is A2 to A2, etc...
 
Thanks you in advance.

In fact I know what object1 is on execution time,Which doesn't help your compiler at all, when it's task to link and verify method calls.
because the code posted at the top is working well, i just want to avoid repeating that if's for all the new classes Ax I will create. Big "code smell" here.
In other words if i had from A1 to A200 i dont want to have 200 if's to cast it to the class it is and then execute it's method.You could call the method "doMagic()" and make it abstract in A. Then you can implement it in all Ax classes and would never have to worry about casting in the first place, because A.doMagic() would automagically do the right thing. Polymorphism.

Variable accessibility: newbie question

My next newbie question:
The following two classes are in two separate files in the same a folder testClass2:
package JavaDemos.testClass2;
import java.awt.*;
public class Sketcher {
    static SketchFrame window;
    static int widthXXX;
    public static int getwidthXXX() {
        return widthXXX;
    public static void main(String[] args) {
        window = new SketchFrame("Sketcher");
        widthXXX=1000;
        System.out.println("output: width = " + widthXXX);
        window.setVisible(true);
        window.specialReport();
package JavaDemos.testClass2;
import javax.swing.*;
public class SketchFrame extends JFrame {
    public SketchFrame(String title) {
        setTitle(title);
        setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
    public void specialReport(){
        System.out.println("number " + widthXXX);
        //     System.out.println("number " + Sketcher.getwidthXXX());
}They don't compile.
I get the following error message:
JavaDemos/testClass2/SketchFrame.java [23:1] cannot resolve symbol
symbol : variable widthXXX
location: class JavaDemos.testClass2.SketchFrame
System.out.println("number " + widthXXX);
^
1 error
Why isn't widthXXX directly accessible from SketchFrame?
Thank you again in advance for any help.

Why isn't widthXXX directly accessible from
SketchFrame?Because it's a class variable of another class. You have to refer to it as Sketcher.widthXXX.

Unix version of Netweaver Dev Studio, Newbie question

Hi,
I have a very silly newbie question. Is there a unix version of netweaver developer studio and if so what is the path to the executable?
Thanks in advance
John

I don't think so. NWDS is built on top of Eclipse which is an open source project by IBM. Check out there site.
http://www.eclipse.org/
As of right now, I don't believe that SAP is offering a Unix version and I doubt that they will.
