Where to put aliases instead of in ~/.bashrc for systemwide effect?

I'd like to make a systemwide alias instead of putting the alias in each users .bashrc file. Where should i put it?
Thanks!

The systemwide .bashrc file is located at /etc/bash.bashrc
It also sources /etc/bash.bashrc.local, so I'd say the proper thing to do here is to create that file and put whatever you need to in there, so that upgrades that change /etc/bash.bashrc won't complain about a changed file.
The previously mentioned /etc/profile.d/ should work just fine too.

I am trying to organize a zip file with a bunch of links and files. But when I drag an image file to a folder, it always "Snaps to grid" instead of just landing where I put it.

I am trying to organize a zip file with a bunch of links and files. But when I drag an image file to a folder, it always "Snaps to grid" instead of just landing where I put it. All of the files are going into the same zip file but I want them visually in the space that I put them and not at the bottom of the snap to grid folder location they are looking like. I am trying to drag and drop files in groups so that I can group them for now, but image files always do their own "sort by" when I drag them from my web pages. Links don't do it though. I tried resetting the folder, and deleting the DS files. No luck.

Where to put the commit in the FORALL BULK COLLECT LOOP

Hi,
Have the following LOOP code using FORALL and bulk collect, but didnt know where to put the
'commit' :
open f_viewed;
LOOP
fetch f_viewed bulk collect into f_viewed_rec LIMIT 2000;
forall i in 1..f_viewed_rec.count
insert into jwoodman.jw_job_history_112300
values f_viewed_rec(i);
--commit; [Can I put this 'commit' here? - Jenny]
EXIT when f_viewed%NOTFOUND;
END LOOP;
commit;
Thanks,
- Jenny

Bulk collect normally used with large data sets. If you have less dataset such as 1000-2000 records then you canot get such a performance improvent using bulk collect.(Please see oracle documents for this)
When you update records Oracle acquire exclusive lock for that. So if you use commit inside the loop then it will process number of records defined by limit parameter at ones and then commit those changes.
That will release all locks acquired by Oracle and also teh memory used to keep those uncommited transactions.
If you use commit outside the loop,
Just assume that you insert 100,000 records, all those records will store in oracle memory and it will affect all other users performance as well.
Further more if you update 100,000 records then it will hold exclusive lock for all 100,000 records addtion to the usage of the oracle memory.
I am using this for telco application which we process over 30 million complex records (one row has 234 columns).
When we work with large data sets we do not depends with the oracle basic rollback function. because when you keep records without commit itb uses oracle memory and badly slowdown all other processes.Hi mc****,
What a load of dangerous and inaccurate rubbish to be telling a new Oracle developer. Commit processing should be driven by the logical unit of a transaction. This should hold true whether that transaction involves a few rows or millions. If, and only if, the transaction is so large that it affects the size constraints of the database resources, in particular, rollback or redo space, then you can consider breaking that transaction up to smaller transactions.
Why is frequent committing undesirable I hear you ask?
First of all it is hugely wasteful of rollback or redo space. This is because while the database is capable of locking at a row level, redo is written at a block level, which means that if you update, delete or insert a million rows and commit after each individual statement, then that is a million blocks that need to go into redo. As many of these rows will be in the same block, if you instead do these as one transaction, then the same block in redo can be transacted upon, making the operation more efficient. True, locks will be held for longer, but if this is new data being done in batches then users will rarely be inconvenienced. If locking is a problem then I would suggest that you should be looking at how you are doing your processing.
Secondly, committing brings into play one of the major serialization points in the database, log sync. When a transaction is committed, the log buffer needs to be written to disc. This occurs serially for multiple commits. Each commit has to wait until the commit before has completed. This becomes even more of a bottleneck if you are using Data Guard in SYNC mode, as the commit cycle does not complete until the remote log is notified as written.
This then brings us two rules of thumb that will always lead a developer in the right direction.
1. Commit as infrequently as possible, usually at the logical unit of a transaction
2. When building transactions, first of all seek to do it using straight SQL (CTAS, insert select, update where etc). If this can't be easily achieved, then use PL/SQL bulk operations.

JNI where to put the jnilib?

I have a smal calculating code, and need it fast done, therefore I will use the JNI.
On MacOSX there is no problem doing this with a dylib, compile the dylib, compile the jnilib put them in the Bundle .. ready to deploy. Easyly done.
On WIN I get a messsage of unknownsource in the ClassLoader., Runtime. and System. loadlibrary(blah)
Where do I have to put the blah.jnilib and the dll to get the applikation used of them??
Must the library path set to get the compiled jnilib run on WIN?? Where do i have to set the path for the jnilib and the dll? DLL in system 32 I guess but where the jnilib???
Or should i just name the prefix of blah when compiling .dll instead of .jnilib, but then I need to manage the file using on different platforms isn�t so??
thanks for help

Windows will find the DLL if it is listed in the PATH environment variable. On Windows XP, I click Start / Control Panel / System / Advanced / Environment Variables. I can then edit the path string which is a semicolon-separated path list.
If you do not want to mess around with the environment variables, you can allways do it M$-style and squeeze the DLL into c:\windows\system32 amongst the other couple hundreds of DLL's already there.

Where to put java code - Best Practice

Hello. I am working with the Jdeveloper 11.2.2. I am trying to figure out the best practice for where to put code. After reviewing http://docs.oracle.com/cd/E26098_01/web.1112/e16182.pdf it seemed like the application module was the preferred spot (although many of the examples in the pdf are in main methods). After coding a while though, I noticed that there were quite a few libraries imported, and wondered whether this would impact performance.
I reviewed postings on the forum, especially Re: Access service method (client interface) programmatically . This link mentions accessing code from a backing bean -- and the gist of the recommendations seems to be to use the data control to drag it to the JSF, or use the bindings to access code.
My interest lies in where to put java code in the first place; In the View Object, Entity Object, and Am object, backing bean.....other?
I can outline several best guesses about where to put code and the pros and cons:
1. In the application module
Pros: Centralized location for code makes development and support more simple as there are not multiple access points. Much like a data control centralizes services, the application module can act as a conduit for different pieces of code you have in objects in your model.
Cons: Everything in one place means the application module becomes bloated. I am not sure how memory works in java -- if the app module has tons of different libraries are they all called when even a simple query re-execute method is called? Memory hog?
2. Write code in the objects it affects. If you are writing code that accesses a view object, write it in a view object. Then make it visible to the client.
pros: The code is accessed via fewer conduits (for example, I would expect that if you call the application module from a JSF backing bean, then the application module calls the view object, you have three different pieces of code --
conts: The code gets spread out, harder to locate etc.
I would greatly appreciate your thoughts on the matter.

Stuart

First point here is when you say "where to put the java code" and you're referring to ADF BC, the point is you put "business logic java code" in the ADF Business Components. It's fine of course to have Java code in the ViewController layer that deals with the UI layer. Just don't put business logic in the UI layer, and don't put UI logic in the model layer. In your 2 examples you seem to be considering the ADF BC layer only, so I'll assume you mean business logic java code only.
Meanwhile I'm not keen on the term best practice as people follow best practices without thinking, typically best practices come with conditions and people forget to apply them. Luckily you're not doing that here as you've thought through the pros and cons of each (nice work).
Anyway, back on topic and off my soap box, as for where to put your code, my thoughts:
1) If you only have 1 or 2 methods put it in the AppModuleImpl
2) If you have hundreds of methods, or there's a chance #1 above will morph into #2, split the code up between the AppModuleImpl, ViewImpl and ViewRowImpls. Why? Because your AM will become overloaded with hundreds of methods making it unreadable. Instead put the code where it should logically go. Methods that work on a specific VO row go into the associated ViewRowImpl, methods that work across rows in a VO go into the ViewImpl, and methods that work across VOs in the associated AppModuleImpl.
To be honest which you ever option you choose, one thing I do recommend as a best practice is be consistent and document the standard so your other programmers know.
Btw there isn't an issue about loading lots of libraries/imports into a class, it has no runtime cost. However if your methods require lots of class variables, then yes this will have a memory cost.
On a side note if you're interested in more ideas around how to build ADF apps correctly think about joining the "ADF EMG", a free online forum which discusses ADF architecture, best practices (cough), deployment architectures and more.

Architecture question...where to put the code

Newbie here, so please be gentle and explicit (no detail is
too much to give or insulting to me).
I'm hoping one of you architecture/design gurus can help me
with this. I am trying to use good principals of design and not
have code scattered all over the place and also use OO as much as
possible. Therefore I would appreciate very much some advice on
best practices/good design for the following situation.
On my main timeline I have a frame where I instantiate all my
objects. These objects refer to movieClips and textFields etc. that
are on a content frame on that timeline. I have all the
instantiation code in a function called initialize() which I call
from the content frame. All this works just fine. One of the
objects on the content frame is a movieClip which I allow the user
to go forward and backward in using some navigation controls.
Again, the object that manages all that is instantiated on the main
timeline in the initialize() function and works fine too. So here's
my question. I would like to add some interactive objects on some
of the frames of the movieClip I allow the user to navigate forward
and backward in (lets call it NavClip) . For example on frame 1 I
might have a button, on frame 2 and 3 nothing, on frame 4 maybe a
clip I allow the user to drag around etc. So I thought I would add
a layer to NavClip where I will have key frames and put the various
interactive assets on the appropriate key frames. So now I don't
know where to put the code that instantiates these objects (i.e.
the objects that know how to deal with the events and such for each
of these interactive assets). I tried putting the code on my main
timeline, but realized that I can't address the interactive assets
until the NavClip is on the frame that holds the particular asset.
I'm trying not to sprinkle code all over the place, so what do I
do? I thought I might be able to address the assets by just
providing a name for the asset and not a reference to the asset
itself, and then address the asset that way (i.e.
NavClip["interactive_mc"] instead of NavClip.interactive_mc), but
then I thought that's not good since I think there is no type
checking when you use the NavClip["interactive_mc"] form.
I hope I'm not being too dim a bulb on this and have missed
something really obvious. Thanks in advance to anyone who can help
me use a best practice.

1. First of all, the code should be:
var myDraggable:Draggable=new Draggable(myClip_mc);
myDraggable.initDrag();
Where initDrag() is defined in the Draggable class. When you
start coding functions on the timeline... that's asking for
problems.
>>Do I wind up with another object each time this
function is called
Well, no, but. That would totally depend on the code in the
(Draggable) class. Let's say you would have a private static var
counter (private static, so a class property instead of an instance
property) and you would increment that counter using a
setInterval(). The second time you enter the frame and create a new
Draggable object... the counter starts at the last value of the
'old' object. So, you don't get another object with your function
literal but you still end up with a faulty program. And the same
goes for listener objects that are not removed, tweens that are
running and so on.
The destroy() method in a custom class (=object, I can't
stress that enough...) needs to do the cleanup, removing anything
you don't need anymore.
2. if myDraggable != undefined
You shouldn't be using that, period. If you don't need the
asset anymore, delete it using the destroy() method. Again, if you
want to make sure only one instance of a custom object is alive,
use the Singleton design pattern. To elaborate on inheritance:
define the Draggable class (class Draggable extends MovieClip) and
connect it to the myClip_mc using the linkage identifier in the
library). In the Draggable class you can define a function unOnLoad
(an event fired when myClip_mc is removed using
myClip_mc.removeMovieClip()...) and do the cleanup there.
3. A destroy() method performs a cleanup of any assets we
don't need anymore to make sure we don't end up with all kinds of
stuff hanging around in the memory. When you extend the MovieClip
Class you can (additionally) use the onUnLoad event. And with the
code you posted, no it wouldn't delete the myClip_mc unless you
program it to do so.

Where to put ConCurrManag, Report and Forms

If you want to export to a CSV file, you'll need to create objects instead. Here's an example that uses the standard AD module:
Get-ADGroup -Filter * | ForEach {
$groupName = $_.Name
Get-ADGroupMember -Identity $_.DistinguishedName -Recursive | ForEach {
$props = @{
GroupName = $groupName
Username = $_.SamAccountName
Name = $_.Name
New-Object PsObject -Property $props
} | Select GroupName,Username,Name | Sort GroupName,Username | Export-Csv .\GroupInfo.csv -NoTypeInformation

CS 6 Image Windows Don't Stay Where I Put Them

I installed CS 6 yesterday. My system runs 64 bit Win 7. In Preferences > Interface, as I did in CS 5, I unchecked both Open Documents as Tabs and Enable Floating Document Window. However, unlike CS 5, in CS 6 images 'insist' on positioning themselves in the upper left corner of CS 6 and will cover both the options bar and the tool bar. For example, this will happen after opening an image if I try to move it or if I enlarge the image window (CTRL-0). If I open two images and try to move one so I can see both at the same time, the one I try to move will not stay where I put it but instead will reposition itself to the upper left, and cover the options bar and menu bar.
As you might image, this makes working in CS 6 difficult and inconvenient. I assume this is a bug, and wonder if there are any workarounds or other solutions. To this point, I have not yet uninstalled and re-installed CS 6. Any suggestions would be appreciated.
Best regards,
David

Hi,
The answer to your question is 'probably'. I like things to stay put, ideally where I want them. So far my feeling is that having the task bar on the bottom is the lesser of the two 'evils'. But your note reminds me to give auto-hide another try. Thanks.

Edit location where iphone4 puts uploaded mobileme video

I have a lot of photos and videos on my mobileme gallery already, and in various folders. How do I tell my iphone 4 where to put the video that I just shot when I select upload to mobileme? It's currently defaulting to a folder that I don't really want it to go to, but I don't know where to find a place that I can tell it to upload elsewhere. Help...

The last 2 queries are getting optional data out of the DB. The user is not required to fill out those fields but if they do, I want to get that data.
I have designed it this way following the instruction of the book "head first php and my SQL" by Head First Labs. It said that you should minimize duplicate data in a table as much as possible to keep them small. Instead put the data in a separate table and reference it with a key. Your tables should only describe one specific thing, so thats what I did. I have them linked with foreign keys and primary keys.
In my case each user can have a vehicle saved for them, maybe 2 or 3. for each vehicle they have the option of listing a car audio setup for that vehicle. Now when they change their setup and update it on the site, a new setup entry is made. That way the old pics/video of their old setup are still correct and all new pics will be correct as well. So essentially each vehicle can have maybe 5. 10 setups linked to it. Hence the separate table for video data, vehicle and setup. make sense?
As for the joins, I was kind of confused on how to do it correctly with my particular queries. And since the 2nd and 3rd queries dont always need to be executed, i thought if i left it as 3 it might save some execution time as only 1 short query needs to be executed.
what is your opinion on the matter?
and what do you mean by procedural language? like if/else?

I changed my iPhone lately but i can't restore my last backup since it keeps saying "itunes could not restore backup because the password was incorrect" but I don't know where to put the password to make it happen... Any suggestions?

Hey guys,
I just bought a new iPhone but i can't restore my backup files beacuse it keeps saying "itunes could not restore backup because the password was incorrect" but I really don't know where to put the password to restore it. I really have some files that are meaningful for me so I really need help. Any suggestions anyone?

Select your iDevice in the iTunes.
Choose the Summary screen (tab) and scroll to the bottom of the screen.
Then un-select Encrypt iPhone backup.
iTunes will then prompt you to “Enter the password to unlock your iPhone backup”, enter the password you set originally.

My computer screen keeps going blank and then going back to the box where I put my password in to start my comp. Why is this happening?

My computer (Macbook) was working fine this am. I left it for an hour and then came back and the screen was black (always does that as the screensaver hardly ever works). I moved the mouse to wake it up and everything was normal. I went to adjust the volume and the screen went blank and the main page with the box where I put my password in when I first start my comp appeared. I put my password in and everything was normal again. I opened a window in Safari and before it loaded completely the same thing happened, the screen went blank and went back to the password box. Does anyone know why this is happening? I don't have an external hard drive or any blank flash drives so I can't back anything up right now and am afraid I'm going to lose everything. Thank you

Sounds like hardware failure, called boot loop. Call Apple and or go on apple.com and make Genius Bar appointment to have your iphone reviewed by a Tech. Provided you iphone shows no physical or liquid damage they will take care of you, or if you have Apple Care Plus

Where to put javascript code?

Hello,
I am trying to set some columns in a list as "read-only" and is using the following code:
<script type=”text/javascript”>
function SetReadOnly()
var elements=document.getElementById(’4_ctl00_ctl00_TextField’);
elements.readOnly=true;
_spBodyOnLoadFunctionNames.push(“SetReadOnly()”);
</script>
But I am not sure where to put the code in. Should I put it in the space in Content Editor Web Part,
or through a link to a txt file, or in "Edit HTML"? I've tried them but none works.
Thanks a lot!
Patrick

You can try this:
1) Open your Sharepoint List. Go to List edit view.
2) On right side of Ribbon you will find "Form Web Parts" option as shown in figure.
3) Choose your List form which you want to edit.
4) Now you can add web part in new window.
5) Add Content Editor Web part.
6) In content editor web part add the path of your "txt" file in which you have written your script, for eg.
<!DOCTYPE html>
<html>
<body>
<script type=”text/javascript”>
function SetReadOnly()
var elements=document.getElementById('4_ctl00_ctl00_TextField');
elements.readOnly=true;
_spBodyOnLoadFunctionNames.push("SetReadOnly()");
</script>
</body>
</html>
I haven't tried this method so I am not sure but hope it works...:D
***If my post is answer for your query please mark as answer***
