Best way to start?

Hi Folks,
What is the best way to get started with ABAP? Your expert advice would help me a lot. I'm working as Senior Database Consultant since last 12 years mainly in Oracle, now I'm thinking to switch to SAP plateform. Any good material, URLs would be appreciated.
Thank you in advance.

Best way to start a new catalog for 2009 ?

Hi,
What's the best way to start a new catalog for the new year, with all the keywords and all the presets of the modules (without having to export all the folders) of previous catalog 2008 ?
Thanks,
Dominique

Well there is a cost too in not being able to find all your images in a single step, and inconsistencies soon develop - eg a keyword is plural in one catalogue, singular in another. Speed or stability issues are not simply related to catalogue size, and I've seen decently-performing catalogues 50% bigger than yours (as well as slow ones of a few hundred images). Have you optimized the catalogue recently?
But if you think it's a good idea to fragment control of your picture collection.... Presets will be carried over to a new catalogue as they belong to the machine (unless you have the save with catalogue preference turned on). Keywords can be moved via the Metadata > Export and Import Keywords command. If you have lots of collections and smart collections, then maybe make a copy of your existing catalogue and then remove all the items from it - making sure you don't trash them of course.

Need Best way to start learning Oracle 11g DBA

Hi.This is Tejaswi.
I want to learn Oracle 11g DBA.I've downloaded all software's and Documentation for Orcl 11g R2. Now. i want to start Learning DBA. Can any one suggest me the best way to Start learning DBA?
Please suggest me the good books For Oracle Architecture and SQL.......

Hello Tejaswi,
The advice you got about reading the Oracle Concepts and 2 Day DBA documentation is very good advice.
I found that knowing some SQL*Plus and SQL Developer was also very helpful as, they both provide a way to interface with the database and try the things you read about. For SQL Plus, I used the book:
Oracle SQL*Plus: The Definitive Guide, 2nd Edition
By Jonathan Gennick
Publisher : O'Reilly
ISBN : 0-596-00746-9 I openly recommend it. It is easy to read, the book is very well thought out, it covers what you really need to know (and more too). The author explains the subjects very well. I would definitely learn some SQL Plus and SQL developer before getting into the 2 Day DBA document (make those 2 days about 7 days each if not more).
To learn SQL, I "sort of" used (I say "sort of" because I only read some parts of it available online and at the local bookstore):
Oracle SQL by Example
By Alice Rischert
Publisher: Prentice Hallit probably has more SQL than you'd need as a DBA but, it is an excellent book you may want to consider.
If you are starting from scratch, as I did, you'll find that you need to learn multiple things at the same time. I believe SQL Plus is the best place to start, along with possibly the Concepts document. That will give you a base to build upon.
HTH,
John.

Please suggest me the best way to start learning about Oracle Purchasing.

Hi,
I have started reading about Oracle Procurement. I have an over all idea of how ERP functions. Anyhow I am like a fresher to ORACLE APPS. Can you pleasesuggest me what is the best way to start learning about Oracle Purchasing.
Is it is throuhg user guides or some thing else..... can you please specify the references also.......
Thank you so much.

If you have a sponsorship, I would recommend taking classes with Oracle University. The other resources are documentation, functional and technical depending on what your interests are.
If you can load Vision database or access vision database (I think solutionbeacon offers a free account to login and play around), that will be another resource as well.
As you learn, join as much user groups like this one, and review all questions and answers in the discussions to understand and learn more.
Hope this helps.

Sysctl.conf - best way to start at boot?

Hi all!
My arch box serves as firewall/router to other boxes on my home network. Obviously, I have to use NAT and net.ipv4 forwarding set to 1 (via sysctl.conf file).
My question is: what's the best way to start sysctl at boot, so those kernel variables are set (forwarding, syncookies etc.)?
Currently, I've:
- put my little script with "sysctl -p" line in rc.d directory;
- call that script from rc.conf;
- sysctl.conf is in /etc .
It works... but, I wander what is the better/proper way of doing it.

Thanks aCoder.
With some other distros, it would be done automatically (sysctl at boot). User just needs to set values of the sysctl.conf file.
With Arch, both steps are manual - and I didn't know any better way. In other hand, that's what Arch is about, eh!
Cheers,
mladen

Migrated new MBPro = slow . Best way to start again without same problem

Hi
I bought a Macbook Pro and on bootup I put my old powerbook with all my data into firewire mode and just migrated things across.
I have been very disappointed with the MBPro speed and have tried to clean it up a bit as I am assuming that Migrating things across has caused this slowness.
I am wanting to do a fresh install but need to get the critical things across
these include my Photo Library in iPhoto and My emails and my iTunes library and my address book. and bookmarks.
I will start from scratch with all the extra applications I have
So when I reinstall what is the best way to achieve this ?
I dont have .Mac accounts but I do have an external firewire hard drive.
To explain where the system is slow it is mainly on boot up and loading for the first time. I checked what was running and everything loaded is a UB so PPC stuff using Rossetta. The spec on the MBPro is standard with the 160gb drive. The powerbook is a 1.5ghz with and upgraded 7200 rpm drive. So I also assume that the PBook drive is a fraction faster but as everything else is way faster in the MBPro I would of though that this would still make the MBPro at least as fast to boot and load things.
It is not alot slower just a fraction but it is noticable. Once loaded the system seems fine and any cpu intensive stuff is way way faster
Thanks

slow startup could be a sign of directory damage, as normal part of the boot process is doing a directory check. booting up on the intel should be much faster, not the other way around. have you tried booting to the install disk and running disk repair?? http://docs.info.apple.com/article.html?artnum=106214 that may be all that is needed to get the boot faster. as well, do you have anything hooked up to the mbpro during startup?? that could also be a factor. as well, if you have not done firmware updates for the mbpro, you should do that as well. this article http://docs.info.apple.com/article.html?artnum=303880 gives up-to-date firmware versions and how to locate them on your mac. from what i gather there are limits in sharing one fw drive between a power pc and intel mac. see this thread. http://discussions.apple.com/thread.jspa?messageID=2950422&#2950422 here is the macosx hints discussion on creating a volume bootable by both types of computers. http://www.macosxhints.com/article.php?story=20060322054212363&query=firewire%2B drive%2Bintel however, you would have to have the space available on the drive, and the inclination to put two different versions (one power pc, one intel!) of the os on one drive, so both volumes are bootable, one with each computer.

The best way to start with JDeveloper

Can anybody tell me what the best way is to start using JDeveloper? Besides Oracle Manuals, are there other ones? Thanks for responding!!

It would be nice if you can specify what is your background. Which tools/languages you used before?
If you don't know Java pick up a Java book that will teach you the basics and the syntax.
A good free online book is : http://www.mindview.net/Books/TIJ/
Then use JDeveloper to do the code samples in the book.
Use this tutorial to understand the basic of the JDeveloper IDE:
http://www.oracle.com/technology/obe/obe1013jdev/10131/introide/introjdevide.htm
Then once you got the basics you should probably try out the ADF tutorial to see how you build a complete Web application that interacts with a database:
http://www.oracle.com/technology/products/adf/learnadf.html
This page also contains the ADF Developer Guide book.
In addition the JDeveloper home page has links to more demos tutorials and how-to's:

What is the best way to start "fresh" with iPhoto '08?

I am running iPhoto '08 on a mid-2007 iMac. When I set up the machine, I moved all the photos from my PC to the Mac retaining the existing directory structure that I had on the PC. I then imported all the pictures into iPhoto with no problems.
Unfortunately, the other person who uses the Mac needs to be able to use the directory structure as it existed on the PC (that structure involves several subfolders with specific names etc.), and it appears that iPhoto is not designed to work that way. I know the photos can still be manipulated in the folders I imported, but then I run the risk of at best, being out of synch with iPhoto and at worst, corrupting iPhoto completely.
That said, what I would like to do is delete or remove the current iPhoto library (or whatever iPhoto accesses; not the whole application unless necessary) and then selectively import photos to iPhoto. That way, the other user can access the photos in the familiar folder structure and manipulate them at will without disturbing the iPhoto db and, once photos are edited etc. and ready for primetime, they can be imported to iPhoto to gain the advantages of displaying using Front Row etc.
My question is what is the best way to achieve what I am looking for? Just backup then delete the iPhoto pkg file in the HD/Library/Receipts folder? Uninstall the entire application and start over?
All assistance greatly appreciated.

ETRA
Welcome to the Apple Discussions.
You don't need to re-install iPhoto, just change the library - and you may not even need to do that.
1. You can easily recreate your Directory structure in iPhoto. Simply start at the bottom of your structure and drag a folder of images to the Source (or left hand) pane of the iPhoto Window. iPhoto will create an Album of the same name. The create your enclosing folders (File -> New Folder) and drag the albums to it. This way you can quickly recreate what you have/
2. The other user of the files can access them directly via the iPhoto Window or a Media Browser such as THIS. The advantage of this system is that your directory structure is available to them ina convenient and recognisable way. They can then drag the pics from the iPhoto Window / Media Browser to the app they as the need. (A whole lot faster than fumbling around in Folder after Folder etc, plus the advantage of keyword searching.)
3. Is this necessary for working with an editor? You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. Btw this is the only way that edits made in iPhoto will be visible in iPhoto.
4. Finally, if you do wish to go as you described: Simply trash the iPhoto Library from the Pictures Folder. Start iPhoto and it will create an new empty library. If you wish to recover the files from the Library first, then Right Click on the iPhoto Library and go 'Show Package Contents'. Your files are in the Originals Folder.

What is the best way to start SAPGUI in a specific transaction

Hello,
What I'm trying to do is to run a Java program that will start SAPGUI (in windows format, not HTML) and present the user with a specific transaction with some data already inserted.
I already managed to start the SAPGUI and I know how to fill in data using the SapJCo but my question is: what is the best way to navigate to a specific transaction? I can activate an RFC of BAPI_CALL_TRANSACTION but it seems like a big overhead. so, can any of you tell me what is the best way activate a specific transaction in SAPGUI using JCo?
Thanks,
Uri Lifshitz.

Uri
JCO are mostly used to executed a RFM on the Destination.
I don't think we could call a Transaction using JCO.
Thanks

What's the best way to start this dashboard?

I have a data set of titles, gender, race, and disability.
I would like to create a dashboard that will be visually appealing to the end user that relies on this information.
What would be the best way to visually represent the gender, race, and disability for each title?
Thanks in advance!
Regards,
Zack H.

Hi Zack
Start with a blank piece of paper and draw out what you think will look ok in terms of the relationships between the data sets you have and a basic structure on areas for controls and areas for visualisations. Then create this mock up using tables/charts etc. Try to select charts which fit the data you have, see [here|http://media.juiceanalytics.com/downloads/graphselectionmatrix_sfew.pdf]
Take it to your user group and discuss, and enjoy the many iterations that follow

Best way to start on capture with no timecode?

To my dismay, I quickly discovered that my cam didn't have its timecode set correctly. Therefore, when I captured, I got a HUGE continuous clip.
1. What is the best way to work with this mammoth clip? I'd love to be able to quickly and manually cut each scene change into separate clips, the way auto detect would have done, so it's more manageable. But if not, how should I start to manage the clip? I'm a former PC Pinnacle Studio amateur, so be gentle.
2. I tried adding a fade in on the front of the clip, and I can't lengthen it from 1/10 second, even if I try to drag over the right side. How do I make it X seconds?
Thanks, FCE community!

You can still make suclips if you like. Search for start/stop points manually or just break it up to say 5 minute intervals. eg:
Move the playhead in the Viewer 5 minutes in, hit the M key. Move the playhead another 5 mins, hit the M key and so on. You end up with a bunch of markers manually placed instead of the auto DV detection style, same deal.
Modify>Make Subclips using the method as already discussed then work with the subbies.
Due to FCE being non-destructive you can also put the one large clip in the Viewer.
Set an in/out point, then edit to the Timeline. Only the bit between the in/out point is edited into the Timeline.
Go back to the Viewer, set a new in/out point then edit to the Timeline on so on.
This method allows for handles so transitions will work OK. Using the subclip method you will need to set in/out points to each subclip if you wish to have transitions with them.
Personally, I'd use the later method.

E2500 / EA2500 Problems - best way to start over?

Hi,
I installed the E2500 software and I thought everything was working except I couldn't access other devices (i.e., if I was on my laptop, I couldn't view the folders on my desktop). Then I realized that besides my secured connection, I also had an unsecure connection (a generically named one called "linksys"). Also, after installation I went out and got an AE2500 adapter for my desktop since its wireless LAN is 802.11b/g instead of 802.11n (which if I understand correctly has better security).
Anyway, due to the issues I'm having and I think I may have missed something in setting everything up (I found a helpful video just a little while ago), I'd like to start over. What's the best way to do that? Can I just uninstall Cisco Connect on my desktop and laptop? or would it be better to use a restore point to go back?
Thanks for any advice and help.

I already tried this before with E series model. Just reset the router and you can download the latest Cisco connect v1.4 software here. That will just set up everything for you and will update the router if needed.

Best way to start services one at a time?

We have a server with a bunch of Automatic services. we sometimes need to stop and restart them. The problem is they each can take 2-3 minutes to start and it kills the whole server if we do them all at once.
So, I'd like a way that Powershell can start one service and then wait for it to start and then start the next one. I also need to do this from a remote machine if that matters.
I know I can get a list of the services via:
gwmi win32_service -computername Server1 -Filter "Name LIKE 'Pro%' and StartMode LIKE 'Auto' and State LIKE 'Stopped'"
But then I'm not sure how to take that and issue individual start commands. Can anyone assist?
Thanks!

This actually works...
$computer = "Server1"
Foreach ($service in (gwmi win32_service -computername $computer -Filter "Name LIKE 'Pro%' and StartMode LIKE 'Auto' and State LIKE 'Stopped'")) {
$service.StartService() | Out-Null
Do {Start-Sleep -S 5}
Until ((gwmi win32_service -computername $computer -Filter "Name LIKE `'$($service.Name)`'").State -eq "Running")
I hope this post has helped!

What's the best way to start a new, LARGE vault?

Hi all,
I have a late 2010 Mac Pro and a 1.8TB Aperture library on a dedicated internal drive. The internal 2TB drive that manages the library has gotten full, so I've just replaced the internal drive to 3TB and copied the library over from the 2TB drive (took about 4hrs to copy).
Now I've got to replace the 2TB EXTERNAL vault drive, with a 3TB external vault drive. I'm wondering how best to go about it?
Should I just create a new vault from within Aperture or copy my old vault to the new drive?
I mentioned I have a 2010 Mac Pro because it only has USB 2.0 (and FireWire 800) ports. I'm guessing it will take days to create this new vault via USB and am wondering if anyone knows the fastest way to go about it ?
Thanks very much

1) Physically disconnect the old Vault drive and put it aside as an archival backup, at least until Aperture and your new hardware have been in _perfect_ operation for a few weeks.
2) Verify that Aperture is working properly and that your Library is fully functional.
3) Attach your new drive via FW800. If the new drive is capable of external (rather than just through FW) power attach the external power. USB also works but is slower and IMO less consistent than FW.
4) Use Disk First Aid to verify that the new drive is functioning properly.
5) Restart the Mac.
6) Enter Aperture and from within Aperture create a new Vault on the new external drive.
7) Keep the Vault drive physically disconnected from the system when not actively backing up to avoid damage from power surges as well as from human error. Ideally store it in a vault and/or off site. A vault drive lost to lightning, fire or theft has no value.
HTH
-Allen
P.S. Personally I recommend against such large Libraries and Vaults. I recommend using a Referenced-Originals Library and backing up originals before entering Aperture. That makes for a much smaller Library and much smaller vaults as well as much safer originals. In databases smaller is by definition better.

What is best way to start up to secure processes with encrypted passwords

Please redirect me if this should be in another Java forum ...
I want to have 2 Java applications running on a secure server. Both contain a password in memory that needs to be kept highly secure. Also, I want each application to be able to restart the application if one fails (I already am doing this with other appications). Finally, I want assurances when an app is restarted, the source is identical to when processes were first brought up manually.
Essentially, here is what I'm thinking about, but there's probably a better way:
Items Required:
App1 Code
App1 Password
App1 Code Hash
App2 Code
App2 Password
App2 Code Hash
When a server is initially brought up, App1 Code is started manually by Admin. App1 will prompt for App1 Password, and App2 Password (Admin will enter these manually). App1 will also display App1 Code Hash and App2 Code Hash. Admin will verify the Hashes match the expected value. App1 will automatically start App2. Upon initially being started, App2 will begin listening on SSLServerSocket. App1 will connect to this socket, and pass App2 both App1 and App2 Passwords, as well as App1 and App2 Code Hashes. At this point, both Apps are running, and both will have both Passwords and Code Hashes in memory. If either App fails, the other App will catch it (through a periodic process check). Before restarting, the Hash of the Code will be rechecked (of the App being restarted), and the Passwords/Hashes will be repassed to the restarted App through SSL session.
Any holes here?
Any better ways of implementing?
Thanks!

First, you should have to Apple IDs
Second, you must have a Wi-Fi connection.
Facetime Calls
To add them go to address book and put in the Apple ID username under email.
Go to facetime, click the contacts button on the bottom. Click the name they gave them. Click the email you used for their Apple ID. It should start a call with the device hooked up with that Apple ID.
Set-Up Facetime
Go to settings. Click facetime. Sign-in with the Apple ID you are using. When someone calls that address it should give you a notification.
Texting
If you are getting a new iPod you will be getting with iOS 5 wich includes iMessage to other iOS 5 devices. Just click iMessage at the home screen and type in the name of the person with the Apple ID you want to text OR type in the Apple ID you want to text. You should start a convorsation with the iDevice hooked up to that Apple ID.
Set-Up iMessage (a.k.a. Texting)
Go to settings. Click iMessage. Sign-in with the Apple ID you are using. When someone texts that address it will notify you.
Hope I helped!

Best way to start?
