Some general domain questions

Hi,
Can some one clear my mind on this, we did some tests the other day and want to check...
We have 3 domain controllers 2008 R2, A, B and C. A and B are located in the same site, Site London, C is located in another site, Site NewYork. forrest and domain functional level are 2008 r2.
- When we powered down domain controller A and B, should not C take over when users logon ? I have check the replication, and its ok between the sites, take 15 minutes before a user account for examlple is replicated. Should not the users in the site for
domain controller A and B only noticed delay on logon (or no delay at all?) ? Does it fails because domain controller A that has all the FSMO roles is down?
- When a user logs on to a domain i can check with the command "echo %logonserver%" which domain controller this users authenticated agains right? There should not be any prefered domain controller for A and B right, this was before when you had
like primary and secondary domain controller i guess. It seems like every clients and servers in the site London authenticates against domain controller A, why is that, is it because this server has all the FSMO roles or since this is the primary DNS
server ?
- Another thing we noticed, was when the domain controller A was down, it was slow loggin on, but there where authenticated against domain controller B at last, but why slow ?
- Another question that not directly related, the customer is using a lot of applications that uses DCOM, they complain that when both domain controllers in site london is down, it fails to authenticate... does this DCOM has any kind of time out values,
sorry my DCOM knowledge is lack..
Thanks for answers and followup.
/Regards Andreas

Hi Andreas,
Based on your description, when the DC A and DC B of site London powered down, all users in London site can’t logon, that is to say, the DC C didn’t take over.
Could users in NewYork site log on normally? Which errors did domain users of London sites get when they logon?
If all configurations are correct, when DC A and B powered down, C should take over when users logon. And all FSMO roles in one DC is not a good choice when we have several
DCs.
To troubleshoot this issue,
Please check the DNS configurations of DNS server and DNS client in London Site at first. Such as if you configured DNS forwarders, and if the preferred DNS server and
alternate DNS server of DCs were configured correctly. You could use dcdiag /test:DNS command to check DNS issues in your DC.
Please run
repadmin /replsummary or repadmin /showrepl command to double check if the AD replicate has any problems.
For more details, please refer to the articles below,
Repadmin /replsummary

Some General Slowness Questions

Hi there,
I've had my MacBook Pro since August 2006. I love it dearly, but in the past couple months (especially since I've upgraded to Leopard) it has been so, so, so slow. Dock taking forever to open programs, frequent appearances of the rainbow wheel of death, I've been needing to use Force Quit a lot due to frozen screens. I don't know much technical information about computers, so I've been at a loss to try to solve this problem. Some questions:
-As an insane college student, I tend to leave my computer on all night, and most of the time in general. I've heard differing opinions on whether this is good or bad. Should I be shutting down every night? Could this be a cause of the slowdown?
-Could it simply be a space issue? I'm using 60 of 74 available GB. iPhoto and iTunes in particular are slow and freeze a lot. I've tried looking at Activity Monitor, but I can't really figure out how to interpret its data. Looking at its processes list, Microsoft Office seems to be taking up a lot of work just when I have it open...right now Excel is using 38 MB (Real) and 1 GB (Virtual) of Memory. Firefox is using 885 GB of Virtual memory. It also seems that I have the PowerPC version of Office, not the Intel version (which is confusing because I bought Office with the computer)--could that be a problem?
-I downloaded an application called Cocktail and have been running it, I guess it's supposed to be a general cleanup type app, not sure if it's making any difference though.
-Sorry, I'm obviously pretty clueless at these things! Thanks for anyone who took the time to read this.

Okay, 512MB RAM, is your issue, you need at least 1GB to run OSX with any resemblance of snappiness. Using 80% of your drive is a fair bit, but not bad. Its good to have 10% of your drive free at any given time (the system will at times use about that much for virtual memory, although maybe more in your case since you have so little RAM). You might want to start looking through your files and see what you do an don't need, since you can fill up a few GBs fast in some situations (such as installing new programs, etc.)

Some General iPhone Questions

As I consider buying an iPhone, I have a few general questions.
1. What are some possible improvements that can be done to the iPhone by Apple via software updates? When do you think we will see these updates?
2. What are some of the possible improvements that can only come from purchasing a second generation iPhone?
3. I want to make this my ONLY phone and ditch a land line for the first time. Is the clarity any better than your average cell phone?
4. I'm not hard of hearing, but some reports have said that the volume is low (for phone conversations) and difficult to hear when used as a traditional phone without headphones. Are there settings on the phone to raise the volume? Can this be a software update from Apple if this is indeed a problem?
5. This would be my first time switching carriers. If I want to keep my current number (from Verizon) would I cancel my service there first or would registering the iPhone via iTunes do that for me?
Thanks,
Steve

As I consider buying an iPhone, I have a few general
questions.
1. What are some possible improvements that can be
done to the iPhone by Apple via software updates?
When do you think we will see these updates?
Since there have not yet been any updates, no one knows for sure. But any improvements in the apps and widgets would definitely be one possibility; also firmware upgrades
2. What are some of the possible improvements that
can only come from purchasing a second generation
iPhone?
Everything can be improved on an updated phone, particularly implementation of 3G.
3. I want to make this my ONLY phone and ditch a land
line for the first time. Is the clarity any better
than your average cell phone?
This is very subjective! I find it to be no worse nor no better then most phones I have owned.
4. \Are there settings on the
phone to raise the volume?
Yes
Can this be a software
update from Apple if this is indeed a problem?
Unknown, but should be possible.
5. This would be my first time switching carriers.
If I want to keep my current number (from Verizon)
would I cancel my service there first or would
registering the iPhone via iTunes do that for me?
If you cancel service with Verizon first - you will LOSE that number!
I do not believe registering the old number with AT&T will automatically cancel your service although AT&T MAY do this.
It would be best to talk to AT&T as to the proper method prior to or at time of purchase.

Some General Issue Questions

Rather than search thru a lot of messages, thought I'd post a
synopsis of all my recent issues and see if anyone has any
solutions/suggestions...
(1) When I publish, some of my "click Next" hot spots (go to
next slide) do not render in the published Flash move files -
however, they truly exist and are properly configured in the cp
file - and seem to work fine in Preview (movie) mode.
(2) The application I'm trying to "captivate" is a web app,
built using a combination of frames, javascript, and dhtml
components. Most of the mouse clicks I make while recording are
useless, as they are usually AHEAD OF what's actually happening
on-screen, although what I'm capturing APPEARS to be accurate and
where I am on the screen. I initially tried do-overs, and got so
frustrated (changing how quickly I moved the mouse, struck keys,
etc.), that I just turned off the Full Motion recording options,
slowed the frames per second - all of these things, several times,
trying different combindations - nothing was successful.
Any suggestions for settings? Basically, I'm capturing a
sequence of screens and putting in all the information into text
boxes and manually inserting click boxes to create a "demo" - in my
opinion, totally defeating the intent and purpose of using
Captivate to begin with.
At this point, I've spent so much time experimenting and
trying to get the "automated" features to work, I've basically
turned them all off and am doing everything manually, just like
PowerPoint.
So, why is Captivate so much better than PowerPoint? Other
than the Flash rendering of the files, I don't see it...
Anybody experience any of these things?
Thanks and regards,
cyn

Hello thiah,
It sounds like you are very frustrated....
1 - I have never had this issue with Next buttons. Perhaps
you can provide more details on the settings on your next button?
2 - I would definitely remove the full motion recording. I
use the recording feature rarely in general, as I need to modify
the screens to change proprietary data. I usually take screen
captures, modify the screen in Photoshop, then insert the bmp image
as an image slide.
But, I find that the record feature it can be very handy and
a quick easy way to create a demo. Captivate is def better than PPT
for many reasons - the timeline, the ability to insert a mouse
movement, ability to publish as Flash, the ability to customize the
size of the movie or demonstration, ability to have click boxes,
buttons, text entries, etc.
As far as suggestion for settings when recording - on the
Recording Options tab, I usually have Enable Auto Recording
selected and I use the demonstration mode, select to record
keystrokes and hear tap sounds, hear camera sounds during
recording, and move new windows inside recording area.
A good tip to remember, if you think that Captivate didn't
capture a screen while you are recording, you can always hit
<Print Scrn> to capture the screen. If it becomes a
duplicate, you can always delete the slide.
Hope this helps. I love Captivate.... it has it's quirks -
but nothing that can't be worked with.

Some general photo questions

I will be undertaking a major project soon that involves scanning all (and I mean every single one) of my family's photographs so that we have digital copies in case something bad happens to the originals. I plan on using iPhoto to store and catalog the photos. But my question is, when I scan the photos, what file format should I use? My scanner (HP Scanjet 3970) can scan to jpeg, tiff, tiff (compressed), bmp, and gif. which of those should I use? Also, I read somewhere that tiff for macs are different from tiff in windows. Is this true?
Also, what resolution is optimal for keeping an archive of photos? File size is not really an issue since I'll be using an external hard drive that's plenty big.

baldrambutan
what file format should I use? My scanner (HP Scanjet 3970) can scan to jpeg, tiff, tiff (compressed), bmp, and gif. which of those should I use?
iPhoto will handle any of those formats. My suggestion for maximum compatibility is to choose between tiff (uncompressed) and jpeg. Why? they're pretty universal, regardless of computer. As to choosing between them? Well jpeg is a lossy compressed format, tiff isn't. The files sizes are huge with tiff, quite acceptable with jpeg. How much editing will you do? IF not much, then there is little re-saving and jpeg will be absolutely fine.

http://en.wikipedia.org/wiki/JPEG
Also, I read somewhere that tiff for macs are different from tiff in windows. Is this true?
Not that I know of.
Also, what resolution is optimal for keeping an archive of photos
The general rule of thumb is 300 dpi is what's required for printing. Screen images require less.

Some general C7 questions

Hi all,
Purchased a C7 recently and just wanted to ask a few general questions, rather than creating a thread for each one.
Does anyone know if there is a way of deleting all messages at the same time. Seems it can only be done one by one?
With regards to the battery, what are your experiences? I find it is running out before the end of each day. It's strange because I gave it the initial eight hour charge and then a couple of times more after to make sure. There is no excessive use at all, just normal.
Also, where can I see what version software I have?
Any responses would be greatly appreciated. Excuse my incompetence, still getting used to the phone and all, quite different from most other phones I've had.

Also if you go into Optionsin Messaging, select other and set show messages in groups, and your messages will be grouped together by date, so you can do a mass clearout and still leave the messages from the last day or two if you wish
It will not affect your battery however long you leave it on charge as the electronics in the phone will stop charging once fully charged, and also giving the phone a 'top up' during the day will cause no harm as modern batteries do not get any 'memory effect'
Good Luck
If I have helped at all, a click on the White Star is always appreciated :

Some general portal caching questions

Hi experts,
I have some general questions regarding caching functions in portal.
1. In System administration->Navigation I can activate navigation cache. By default there are 3 connectors: Collaboration Connector, ROLES and gpn.
I guess Collaboration Connector caches Collaboration Content and Roles caches the content of the Role-based navigation? Is that correct? What is gpn-connector?
2. This cache does only cache the navigation structures? Not the iviews and the content?
3. For some iViews and pages I can activate caching in PCD with certain cache levels. That caching is not related to navigation caching?
4. I can't activate caching for web dynpro Java iviews and web dynpro java proxy pages. Is that corect? If not how can I achieve that. Those settings are deactivated for me, so I can't activate them.
5. In Visual Admin I can activate navigation cache under com.sap.portal.prt.sapj2ee. Is this option related to the setting I can set under system administration->navigation in portal? Because I avtivated the option in portal but in VA it still showed it as not activated.
I crawled some documentation but couldn't find exact information.
Thanks and regards
Manuel

Hi,
1. GPN is Guided Procedures Navigation connector
2. Yes only Navigation nodes are cached (TopLevel and Detailed Navigation nodes)
3. Here it is PCD Caching, which has nothing to do with Navigation caching
4. I never tried this, but It looks like what you say is true.
5. What you see in VA is old caching mechanism. So this is obsolete and can be ignored.
So you should only use the options from system administration->navigation
Changes in the Navigation Cache

Some General iPhone 4 questions

We just bought my wife a used iPhone 4 and (a little late now) we have some questions.
Generally the questions revolve around the issues the iPhone 4 had when they were first released - something about the antennae location. How was that resolved? and if so how?
Is there a way to determine when an iPhone was manufactured or how old it is?
I see in the forum 'refined' lineup there are iPhone 4 forums for both GSM and CDMA - where is that shown on the iPhone?
The primary issue we are having is with signal strength. Since it's 'hers' I only hear about it so don't get much chance to see for myself.
Thank you for any help

Some general questions about swing

Hi,
I used to do some swing development couple years back but since then I have been more involved in the j2ee scene. I have lost some touch and was wondering if some of my questions can be answered. I'd appreciate every effort.
First of all, I am trying to make an applet that can be used to upload multiple pics at the same time. Similar idea to facebook picture upload applet. My Q's are
-> can every swing application be turned into an applet? or when the developer starts writing an application he should write it from an applet POV
-> I noticed that the applet on facebook looks a lot like a window application. icons and the look and feel of the application is not that of a applets i saw couple years ago with sun java look and feel, how can this be achieved? is there some small example?
-> can someone suggest an example || tutorial of an applet that shows how to upload an image to the server?
and lastly for mental satisfaction :)
-> how hard do you think it is to build such an application. I assume it will just have a JTree on the left side and on right side it will show contents of the folder that is currently clicked.
Thanks for your time

thanks for the tutorial link.
However, the tutorial explains how to show icons from images. But what about in my case when the images arent even on the server yet.
Basically when the user is browsing files and gets to their my pics folder on the right side i want to show icons of images in that folder. for this reason i doubt I will be able to use what they've implemented in that tutorial. As the pics havnt yet been uploaded by the user i have no direct access to the images.

A few general agent questions

We've been asked some general questions by our agents that I have been unable to find answers for, (although 4 and 5 are likely working as designed). We are running IPCC Express 7.0(1)SR05_Build504 and these are all phone agents. We do not run the agent desktop client. Any assistance in answering these questions would be greatly appreciated.
1. TransfertoVM softkey "grayed out" while on a CSQ call. Can it be enabled?
2. While logged in to CSQ, is there a way to start dialing prior to
lifting the receiver?
3. Is it possible to handle more than one CSQ call at a time, e.g. put a call on hold and answer
another CSQ call.
4. Upon selecting Agent Login (single-button login), can the agent automatically be put into Ready?
5. Upon Logout, can the phone be returned to the main screen, rather than getting the manual agent login screen?
Again, any assistance in answering these questions would be greatly appreciated.
Thanks,
Roger

Hi
1) Isn't that an IPMA softkey? Never tried it, but whilst it's not in the 'unsupported' list, I wouldn't expect using any IPMA features in conjunction with CAD would get you good results. If it doesn't cause you stuck/ghost calls, I would expect erroneous reports...
2) Being logged into a CSQ doesn't affect the way the phone works.
- You can dial the number then either lift the handset or hit dial (for speakerphone)
- You can press speakerphone or headset then dial
I guess what you are referring to is if you are using the IP Phone Agent in conjunction with a headset? If you are, then the IPPA usually obscures the 'new call' and 'end call' softkeys that you might use if you leave the headset button lit. I guess this isn't the case, as you refer to lifting the receiver? Unless you have motorized lifters.. If that's what you have, you can try getting users to either :
- Manage their onhook/offhook state using the headset key as if it was the speakerphone key (i.e. press it to hang up or pickup)
- Use a headset/phone combination that supports HHC
- Switch to CAD, or CAD-BE if you can't install PC software for some reason.
3) No. The system is designed specifically so that this should never happen.
4) No.
5) Again, no... you can't customize the BIPPA service... If you use CAD or CAD-BE this wouldn't be an issue.

10.3.5 sluggish on my iMac (and some other newbie questions)...

I just purchased an iMac, and am brand-new to Macs. I can do anything on a PC, and actually do PC tech support for a living, so you can imagine that I feel completely ridiculous asking some of these questions, but here goes:
1. How do I copy and paste? Ctrl+C does not work.... surely there is another alternative?
2. Is there a way I can download OE for Mac? I know Microsoft no longer offers downloads or support, but if there is another place I could find ol'familiar Outlook Express, that would be fantastic.
3. My browser (either IE or Safari) is not completely maximized. There's the area below, and an area to the side with some icons as well... is this the maximum size of the browser, or...?
4. Right now I'm running OS 10.3.5, which seems a bit sluggish. It came installed. I also have the discs for 8.6, and if it will make the system run better, I'll definitely ''downgrade.'' How would I do this? Do I have to ''reformat'' or anything like that?
5. Are there other tweaks, sort of like MSCONFIG, that will help speed up my system in general?
Here are my system stats:
iMac (Grape!), 333MHz, 6GB Harddrive, 196 MB RAM...
It's a G3 CRT, I think (if that matters).
Any help would be so much appreciated!

Hello Tiffany,
First of all, Welcome to the Apple Discussions!
In regards to your #4, I would just suggest running Software Update (after upgrading the RAM memory if possible) and upgrading to the latest version of 10.3 that should be offered to you, ie. 10.3.9). As the other posters have suggested above you should upgrade your RAM to at least 256 MB. With any updates to system software, remember to Repair Permissions from Disk Utility found at HD/Applications/Utilities/Disk Utility before and after the update.
There are many "tweaks" and troubleshooting information for OS X that you can perform to get the best from your OS and machine.
Some great information can be found @:
http://www.thexlab.com/faqs/faqs.html
A great tip, as your machine has a very small amount of Disk space is to run a little app called Delocalizer that will free up alot of space taken from Foriegn language files. The link to it can be found in Dr. Smoke's FAQ for "Freeing space on your Mac OS X startup disk".
hope that helps some,
littleshoulders [:-)

Best Font for Subtitles? and other General Subtitling questions?

I've never had to use subtitles, until my current project, so I am looking for some general advice and suggestions.
I will be using PPCS3 (on XPpro) as the subtitles (as in the kind that translate a foreign language) will be permanent.
So here are my questions:
1. What is the best font and or what is the most standard font for subtitles? (Font size and other characteristics may be worth mentioning here too.)
2. Is it possible to have an outline around the text as opposed to shadow?
3. What are some general rules of thumb for subtitles that apply to broadcast and cinematic productions?
Thank you.

Can I use coherence as follows? (General architecture question)

I'm working on creating a "web service" that will typically
- Receive a request and log it.
- Process
- Reply to "client" and log it.
The idea is to put the logs into the grid and finally to SOR?
Of course the logs need to be parsed, searchable etc...
Does the above make sense?
And some general questions...
If coherence is configured as partitioned do you really need a SOR, can it replace the SOR?
Can I have coherence running on seperate machines and the web service on other servers?

It makes perfect sense.
You can use a CacheStore to asynchronously ("write behind") to write your log entries to the system of record. You can implement a LogEntry class which would wrap the log messages, and expose getters for the attributes you wished to query by. You can configure an evication policy to determine how long LogEntry's should remain in Coherence.
So long as you have sufficient memory for the amount of data you wish to store (and backups, if necessary), yes Coherence can replace your SOR.
Yes, Coherence can run on different servers. Your web service layer can be configured as a "storage disabled" cluster member, or connect to the cache servers using Extend.
