Many little datafiles or one big datafile?

Hi all
I have a database which grows every day. I have 10 datafiles with name users01.db , users02.dbf and etc.
And all these datafiles have 1.5Gb size. Each time every datafile reachs it's 1.5Gb size, I add new datafile. Is it correct strategy? Or I must add only extents to last datafile and allow it to grow?
Thanks...

Hi,
In my point of view, it is a good approach if "table striping" is used, where data is spread across more than one device. Otherwise, if you have just one disk, then I don't see advantages or disadvantages. In addition, take a look at [url http://forums.oracle.com/forums/thread.jspa?messageID=1041074&#1041074]more small datafiles or one big datafile for tablespace thread.

Many small purchases, or one big one?

Hello, I'm actually really new to the credit world and just got two cards, a Chase Freedom and a Discover IT for Students. I want to get started building my credit and increasing my credit limit. I realize it's a slow process, (and maybe getting two cards at once wasn't the best idea) but I want to make sure I don't needlessly slow down this process.
My main question is, are many small purchases in a month better than just one big one, or does it even matter?For Example…
Chase Freedom CL: $1200
Discover IT CL: $1000I was hoping to use these cards to make payments on my tuition. If every month I only spend a $200 payment from my Discover card, is that better or worse than just buying 20 items at $10 apiece?Again though, the ultimate goal is to increase my CL and CS.

Great cards to start on. I wish I had gotten two in college. I just graduated and got my second. Like others have said, the amount of charges doesn't matter as long as you keep your overall and individual util at or under 30% which you would be doing at the charges you're describing. if need be, don't shy away from making multiple payments in a month to keep your util low while using the cards as much as you like (responsibly, and within your need/ability of course) while earning the rewards. Enjoy building. You're definitely off to a good start!

More small datafiles or one big datafile for tablespace

Hello,
I would like to create a new tablespace (about 4 GB). Could someone if it's better to create one big datafile or create 4 datafiles with 1 GB each?
Thank you.

It depends. Most of the time, it's going to come down to personal preference.
If you have multiple data files, will you be able to spread them over multiple physical devices? Or do you have a disk subsystem that virtualizes many physical devices and spreads the data files across physical drives (i.e. a SAN)?
How big is the database going to get? You wouldn't want to have a 1 TB database with 1000 1 GB files, that would be a monster to manage. You probably wouldn't want a 250 GB database with a single data file either, because it would take forever to recover the data file from tape if there was a single block corruption.
Is there a data files size that fits comfortably in whatever size mount points you have? If you get 10 GB chunks of SAN at a time, for example, you would probably want data files that were an integer factor of that (i.e. 1, 2, or 5 GB) so that you can add similarly sized data files without wasting space and so that you can move files to a new mountpoint without worrying about whether they'll all fit.
Does your OS support files of an appropriate size? I know Windows had problems a while ago with files > 2 GB (at least when files extended beyond 2 GB).
In the end though, this is one of those things that probably doesn't matter too much within reason.

How to split one big master clip into many?

Hi,
This is probably a simple question for you pros. Thank you for reading.
I have film that I've telecined onto a DV. However, FCP imported a one hour tape as one big master clip. Is there a way I can split this master clip into several small clips so I can organize my project?
Does that make sense?
Thank you in advance,
Nik

Since you telecined onto DV I guess there are no Date&Time gaps between scenes, so you cannot use DV Start/Stop Detect. Then the only way I can think of is to do it manually: open the clip in the viewer, select the first scene by setting its IN and OUT points, edit to the timeline, back to the viewer select the next scene setting a new pair of IN and OUT points, edit to the timeline, etc.
If you prefer you can move each new clip to the browser, and collect them together into a bin, before editing them to the timeline.

Best Practice for Many Complex Elements In One PNG File

I use Fireworks all the time, but I'm still embarrasingly ignorant on how to do some things property.
For instance, when I do mockups of a new customers homepage, there may be many small or medium sized complex objects on the page. By "objects" I mean like lots of modules advertising their different services, and each module has its own graphics, text, backgrounds, etc all with lots of different effects applied.
Should all of these things reside in one large png file, or does Fireworks offer some way for me to create some of these as separate png files and just drop an "instance" of them into the main file? I read something about adding files to the Common Library, but I will only need these files for one single customer so that may be overkill.
Or do I even need to worry about separating them at all and should just continue having everything for a single customer in one big single png file?
Please let me know if my question is not clear.

In reading a bit further, it looks like a good option for me might be to just select everything that makes up a specific module and just "group" it. That way I can move it around and turn it off and on easier.
So I'm thinking that unless theres something Im going to reusing more than once in a document (which in this case I'm not) then its fine to have everything all in one png? And the only time I use the Common/Document Library is when i'm reusing things?
I'm just trying to wrap my head around what all my options are in Fireworks, as so far my experience is limited to just dragging around rectangles and shapes and stuff on one single canvas to create website mockups.

Variable number of two dimensional arrays into one big array

I have a variable number of two dimensional arrays.
The first dimension is variable, the second dimension is always 7.
i.e.:
Object[][] array0 = {
{"tim", "sanchez", 34, 175.5, "bla", "blub", "[email protected]"},
{"alice", "smith", 42, 160.0, "la", "bub", "[email protected]"},
Object[][] array1 = {
{"john", "sdfs", 34, 15.5, "a", "bl", "[email protected]"},
{"joe", "smith", 42, 16.0, "a", "bub", "[email protected]"},
Object[][] arrayi = ...I'm generating these arrays with a for-loop:
     for (int i = 0; i < filter.length; i++) {
          MyClass c = new MyClass(filter);
          //data = c.getData();
Where "filter" is another array which is filled with information that tells "MyClass" how to fill the arrays.
"getData()" gives back one of the i number of arrays.
Now I just need to have everything in one big two dimensional array.
i.e.:Object[][] arrayComplete = {
{"tim", "sanchez", 34, 175.5, "bla", "blub", "[email protected]"},
{"alice", "smith", 42, 160.0, "la", "bub", "[email protected]"},
{"john", "sdfs", 34, 15.5, "a", "bl", "[email protected]"},
{"joe", "smith", 42, 16.0, "a", "bub", "[email protected]"},
Any idea on how to accomplish this? It's blowing my mind right now.

Just brainstorming here:
Why not put your actual data in a class and store that in a LinkedList (so you know the total number of elements for your multi-dimensional array). Then initalize your multi-dimensional array and populate it? Haven't tested the following, but thinking something along the lines of
public class MyData {
     //data here
     public Object[] toArray() {
          //something similar to this
          return new Object[] = {"tim", "sanchez", 34, 175.5, "bla", "blub", "[email protected]"};
LinkedList<MyData> data = new LinkedList<MyData>();
data.add(mydata1);
//however many times you need
Object[][] arrayComplete = new Object[data.size()][7];
for(int i = 0; i < data.size(); i++) {
     arrayComplete[i] = data.removeFirst().toArray();
}Another option for knowing how many rows you would need might be using something like:
int rows = 0;
rows += array1.length;
rows += array2.length;
//etc...But is not entirely useful if you don't know how many variable arrays you have (although reflections might help if the name of the array variable is incremented systematically, someone told me earlier to avoid reflections since it could make debugging a LOT more difficult).

From many input jars to one out put jar

Hi,
I want to read many jar files and generate one big jar file as output. The output file must contain all information from the input files. As all of them are .jar files I suppose I can't just copy the content from the input files to the output file, right. What would be the best approach to accomplish this task?
Thank you in advance
Best Regards

Quit trying to piece together a new jar containing bits and pieces from other jars. Just distribute all the required jars.

One Big Clip

Is there a way to merge many clips into one big clip and keep it in the same bin. You can do thie with Edius. It's convenient when you have many clips of one subject. You have them in sequential order with timecode. It's helpful and fast in news editing.

This worked for me. I selected all the clips that I wanted to use. Right clicked and chose New Sequence From Clip. It created a new sequence with all the clips in order. I just renamed it and I'm using it as the source.

Choosing one big ssd drive or better having a second hdd

I WANT TO REPLACE MY INTERNAL 320 gb hdd with a SSD, is better have a second drive (as my actual hdd) for data or one big ssd whee to put everything on is a best solution even for battery etc
what is the incovenient to have one only SSD.

alidav,
It's quite nice to have a 1TB SSD (mine is almost 1TB at 960GB) and I certainly recommend buying a SSD that fits your needs. However, I would recommend that if you do buy a 1TB SSD that you also invest in, at the least, a 2TB external drive for making Time Machine backups. I use both two Time Machine drives and five clones for my backup needs (a little paranoid, I know) but I have to recommend at least one, if not more, backup schemes.
Good luck,

Putting a game inside one big movieclip

I'm using the script below on a movie clip that moves and
interacts with other movie clips. the movie clip the script is
applied to is on it's own keyframe on the timeline in the main
scene. now, i want to put everything i just made (the movie clip
the script is applied to and the movie clips it interacts with)
into one big movie clip so i can easily put it on a flash based
website. I'm pretty sure the "_root." has to be changed but I'm not
quite sure what to change it to

Jale3,
You are absolutely correct. _root refers to the main timeline
of a movie. By restructuring your timeline, many of the paths no
longer refer to actual MovieClips. There are a few ways of fixing
this.
1. Using an absolute path again. If you give the "one big
movieclip" an instance name of "big_mc", you would change all the
_root's to _root.big_mc. However, this method is not recommended as
it is what caused the problem in the first place.
2. Using a relative path. Clearly, the MovieClip with the
above code will always be on the same timeline, with the wall and
win MovieClips as well. And so, if this clip "looks" for the others
from its point of view, then there should never really be a problem
where you place the game. In this case, you could replace _root
with this._parent. "this" simply refers to the current timeline (of
the MovieClip that the code resides on) and "_parent" refers to the
parent timeline from the specific MovieClip.
3. A third, lazier option would be to make all references of
_root refer to the "big movieclip" and this can be achieved with
one line:
big_mc._lockroot = true;
Despite being the easies fix, the second method is a better
approach as there might be complications of some sort down the
line.
By the way, you might want to look into the onEnterFrame
event handler as a replacement for the outdated onClipEvent.
