Running HTML DB apps on one machine with the database on another
I first want to apologize for this question being asked AGAIN.
I have spent the better part of the day reading through a lot posts regarding this issue (and there are a lot). My boss sent me this requirement on a new project that Oracle Forms and Reports run on one server and connect back to the database on another server for security. HTML DB needs to do the same thing.
The question:
I have found out that the DAD file needs to be modified to allow this type of set up to work and the HTTP server needs to be running on that server. He is asking what in the DAD file needs to be changed to allow this to work. Would someone provide me with an example of what would need to be changed?
Also, I'm confused on the implementation of this. Currently all the applications I've created are for "in-house" users. This project is the first (that I've done) that is going to be open to users outside the company. I'm confused on the link that will be supplied to the users. After I import my application into the production database, I run it to get the link and send that to our users. If the application is going to be run from a different server from the database, how is/will the link to run the application be built? I hope I'm describing this well.
Thanks,
Joe
Joe,
You wouldn't have the database server "open to the outside world". All you'd need to have open would be the port for HTTP traffic.
There are two scenarios -
1) Having them both (DB & Apache) on the same machine
You would still only have the HTTP port open. The "fear" is that if the Apache server is compromised then they have access to the database machine.
2) Having them on separate machines.
In this case if the Apache server is compromised then, since by definition, you have a route from the Apache server to the DB server then they can still reach the DB machine from the Apache server machine.
The thing to do here is to ensure your Apache server is patched and secure, regardless of whether it's running on the same machine as the DB or not.
I'd be interested to see what others think.

Connect motion of one object with the size of another?
I am sure this is possible but I am not quite sure how. I would like to connect two objects, say a wheel and a line. I would then like to move the wheel and have the line increase in size so that it stays linked to the wheel. Any idea how I would accomplish this feat?
While it is not specific to your situation, Mark Spencer does demonstrate the Link behavior here:

Entire environment on one machine with zones
I've been pondering some of what zones can do, and it occurred to me that one could build an entire reasonably secure environment using one machine with multiple zones...
* Global zone with no network ports active, console only
* One zone for firewall, heavily ipf'd - mapped to external and internal network ports
* One zone for webserver - mapped to internal network port
* One zone for fileserver - mapped to internal network port
* Other zones as needed - probably all mapped to internal network ports
* All zones secured with ipf to allow very little access, particularly from firewall zone
It seems like this would allow a very flexible environment, and would give the security of having multiple boxes.

Thoughts/Comments? You are definately on the right track. If I haven't said it before, I will say it now - All services that can be, should be run in a zone. That means web servers, DNS servers, LDAP, file servers, etc. Between zones and least privilege (you are using least privilege aren't you), you can create a very secure and contained service environment.
Imagine the surprise of a script kiddie when by pure luck they compromise your zone, but sadly they can't install their favorite rootkit because /dev/kmem, /usr, /devices, etc. are completely off limits no matter how much they scream about having UID 0. Remember, this is even more secure than having multiple boxes; this is like having multiple boxes where root ain't root. The best part is that zones are cheap. You can create them at will without performance impact, and can limit resource usage via a number of different means.
There is a new paradigm in town and it's name is Zones. Use zones and use them often. This is a no lose proposition.
Happy zoning.

i tied to sync my ipod to the itunes but, the apps wont sync it just says the apps will be replaced with the ones on the itunes library,but there isnt any apps on there, i deleted all the apps after i use to use the library for my old iphone helpp, the ipod used to be synced with a another i tunes libary that i have deleted now

You can only sync with one ITunes library. It you switch iTunes library iTunes will erase the iPod and replace it contents with what is in the library of the new computer. -
WebLogic Error : Registered more than one instance with the same objectName
HI there, I'm facing a big problem. I have two environments installed on the same physical machine.
I have ALSB and WLI servers running out there.
Environment 1 - WLI port running at 7011 domain name : stp_wli_domain and ALSB port running at 8011 domain name: stp_alsb_homo1 - folders- stp_wli_domain / stp_bea_alsb_homo
Environmnet 2 - WLI port running at 7211 domain name : stp_wli_domain2 and ALSB port tunning at 8211 domain name : stp-alsb_homo2 - folders - stp_wli_domain2 / stp_bea-alsb_homo2
Everything was working fine, but these days I had install new deployments on both environment and I got this error :
java.lang.IllegalArgumentException: Registered more than one instance with the same objectName : stp_wli_domain:ServerRuntime=wli_wls01,Name=stp_wli_domain,Location=wli_wls01,Type=AIRuntime new:com.bea.wlai.management.AIRuntimeMBeanImpl@bcf22dc existing com.bea.wlai.management.AIRuntimeMBeanImpl@de02e6c
The weird is : There is no same object name, as you can see, domains are different, folders are different and ports are diferrent, including multicast addresses.
Have you guys seen this before ?
I'm under pressure here, 'cause some projects had stopped to work.
Please I would appreciate any help.
Tks.
EdsonHI there, thanks for attention..
See ...
There's a lot of confusion with these env's .
I did not built this, so... I'm cleaning my hands.... anyway... :)
I must fix....
Well basically if we have two env's, so we have different project each one right ?
Ok, but I was told that if you have on the same network and same physical machine the name of AdminServer as "AdminServer" in all domains, so it goes with problems... I never heard about it... but is a good practice you put the names for example :
WLI - WLIAdminServer
ALSB - AlsbAdminServer
WLI2 - WLiadminServer2
ALSB2 - ALsbAdminServer2
I would do it.. this way..
But how it wasn't me...
We got..
WLI - WliAdminServer
ALsb - AdminServer
WLI2 - AdminServer
ALsb2 - AdminServer
Have you got it ?
So... I was told that this could be a problem, almost all AdminServers with the same name... guess what ?Some Projects are back to work. but not at all.. only some.. so I 'm breathing better now... but I would like to know if you seen this before ?
I would appreciate your help again.
Unfortunately there's no detailed stack trace to track this
Tks. -
i changed my sim on my iPhone n reconfigured iMessage, it configured with my number but when i sign in with my apple id it says username/password is wrong while in all other things like FaceTime, App Store it worked with the same id and password..
can anyone help me to solve this issuei just opened my ipad, started my apple account/I.D. and realized I put the wrong e mail. I was having trouble correcting my I.D on the Ipad so I went to my laptop and make the proper changes/slash e mail address I wanted for my apple ID. I got back to my ipad and try to download an app I can't because I have to sign in my apple account and I can't because it still has the irrelivant I.D/email address..
So, i did what you said.. went to setting>app store> tapped on my e mail.. it asked me to sign in (with my invalid emails address showing). I signed in with the password I had created. It said "incorrect".. I went to reset password. I reset password, tried to sign in and it says again "unvalid password".. this is getting irritating. I have been asking and no one knows what to do. -
Is there anyway to take a downloaded app from one computer and put it on another without rebuying it. I have a macbook that I bought the new iMovie and iPhoto on, but I would rather it be on my iMac. So is there anyway I can change it? I thought that if I bought it the apps on my macbook, they would be avaliable on my imac like the mobile devices operate. The macbook has 10.6.8 cause its a older model and I think lion would slow it down. Any help??
Just redownload it on the other computer by logging into the App Store with the same Apple ID you used to purchase it.

how can I change my iphone username to update apps and download anything with the new email I have today?
Before you make an apple ID with the new email, go to appleid.apple.com. login with your old email and password. change your old email to your new one. Now you can use your new email as your apple id, but beware if you go through the process of creating a new appleid with your new email address you will not be able to attach your old account to your new email.

Hi,
( I search for iChat questions when I have finished in the iChat Forum)
So the menu bar reads iChat, File, Edit, View, Buddies, Video, Window and Help
There is no Buddy List open.
There is no other window for iChat open.
In the iChat Menu you only have access to Status.
Is an item ticked in the list ?
Is this a green (Available item) or Red ( an Away one) ?
Can you access the Accounts option ? (Sitll in the iChat Menu)
Is anything in here ticked ?
In the Window menu any Logged in account should appear in the list (Between the Next Chat and File Transfer items)
It would be useful to know which version of iChat this is.
If no account is ticked (iChat Menu > Accounts) or not showing in the Window Menu, plus you cannot determine the Status and you cannot access the Preferences then you need to access your Home Folder/Library/Preferences
As the Library in the Home Holder is Invisible in Lion you will need the Finder's Go Menu > Go to Folder option (you can use it in earlier OS versions if you want)
Type in:-
~/Library/Preferences
Find the file called com.apple.ichat.plist
Drag it to the Trash and Restart iChat.
This will lose all the settings in iChat that you have changed from Defaults but there is no way around this.

If you registrate one Apple ID for each iPhone/iPad, you'll get 5GB on iCloud for each Apple ID, right? I have two iPhones and one iPad with the same Apple ID, why can't I get 5 GB fo each of them?
Actually, everyone missed one point, when a device is priced, the cost of icloud storage space for that device is also included in it that is why they are able to give you 5gb each for each user ID, in nutshell there is nothing free coming with apple device purchase, it is paid for. What they are trying by giving only 5gb per user ID irrespective of the number of devices used is pure broadlight looting, they take money from you when you buy each device and give you nothing, This is a case of goods and services bought but not fully deliverd ie apple can be suied for discreminatory treatment towards it's users. I wonder why no one tried this yet in America where everyone sue everyone for petty things..... there is no one to take up this issue? . if tim got any love for the guys who shell out money for the devices his company makes, he should be implimenting this as priority before someone wake up from sleep and sue him.

You made a purchase and exhausted the credit on your card before it processed. All purchases are final. Contact iTunes Store support. You need to settle up before you can purchase or download anything else.
