Can't get connected to the database

Hi There,
I am a novice to Oracle. I recently installed Oracle 9i Personal Edition in my PC. I also installed 9i Developer suite, however i'm having problem connecting to the database everytime I run for instance, Form developer, report developer or Desginer. I get A Network dial up box. It ask me which network connection I'd like to use. It seems that the applications offered by the 9i Developer attempt to connect into server and in fact I'm runing the database on my pc not from a remote server.
I appreciate any help regarding this isssue.
Thank you
Ayache.

Step 1 : If you have several Oracle Homes at your PC you have to choose as primary Oracle Home the Oracle Home belonged to the Oracle Server. Do it so:
SELECT START> PROGRAMS> Oracle Installation Products> Home Selector
Step 2: tell me how many databases you have created and what are the SIDs of them.

I am trying to setup wireless using my old dome Airport ExtremeBase station. I had previously used it about 5 years ago when I had dial up but have now switche to DSL with Windstream. I can not get connecte as ABS keeps trying to dial up(the phone number)

I am trying to setup wireless using my old dome Airport Extreme Base station. I had previously used it about 5 years ago when I had dial up but have now switched to DSL with Windstream. I can not get connected as the ABS keeps trying to dial up(the old phone number). When I tried to change my network settings an annoying popup window says "your network settings have been changed by another application'. I have no idea what the message is all about and when I close this window it immediately pops up again and prevents me -as far as I can tell -from changing my Airport settings? I need advice on how to get this wireless setup done. Maybe a reset? or something else? I have the DSL phone line plugged into WIndsteam Seimens Speedstream 4200 modem and then the ethernet (yellow) wire from the WIndsteam Seimens Speedstream 4200 modem to the port on the dome that is a circle of dots.

1)Can you explain how using the AEBS as a bridge will work with the Seimens Speedstream4200?
As a bridge, the AEBS will basically become a wireless access point. This will allow the AEBS to provide a wireless network, but still allow the Speedstream to provide NAT & DHCP services for the wireless clients connected to the AEBS. If the AEBS was left as a router, you would have a double-NAT condition which isn't necessary bad in itself, but would create a second subnet. That would make it more difficult for clients connected to the AEBS to access clients connected to the Speedstream.
2) Is there a link that will guide me through the steps to set the AEBS as a bridge?
You can easily reconfigure the AEBS as a bridge using the AirPort Utility.
ref: AirPort Utility > Select the AEBS > Manual Setup > Internet > Internet Connection > Connection Sharing = Off (Bridge Mode)
3)Can I just connect the DSL phone line to the AEBS and eliminate the Speedstream4200?
Unfortunately no. The AEBS does not have a built-in DSL modem. You will still need the Speedstream to provide this function.

Connection to the database and session

Friends I am developing a JSP based application ,and I am storing Connection (to the database) info in a session variable in my main menu , and then I retrieve the connection session in all the pages that I navigate to.
But a friend of mine told me it is not a good programming practice.He adviced me to use the connection pooling to make effecient use of the connection.
So using session for storing connection to the database is a bad idea ?
I thought it is bad idea to get connected to the database everytime a jsp is thrown ...hence I was using session variable.
Please give ur thought about this.
Thanks.

Well.
You are using a kind of connection pooling already, since you make a connection and reuse it along every jsp page in a session but reusability is at the cut&paste level here.
And what would you do if you needed to share a connection between sessions (scope:application)
Or how would you resolve the need to connect to 2 databases in one JSP page ?? Duplicate the code from the "main menu" ?
If you have let's say 5 applications written as you described and the connection data (ip address, SID, host) changes as someone moves the database to another machine (for example :-))) you will have to manually correct all 5 applications. So it's not much of flexibility in this kind of code.
Connection pooling as I understood it (I might be wrong :-))) is placing the code in a bean or servlet and the parameters in a txt (or better xml) file so when something changes you don't rewrite applications, just rewrite one txt (xml) file and you are done.
If you use a connection pool as a bean you have the bean scopes you can choose from and so on.....
Visit
http://www.codestudio.com/index.shtml
for an example of a very well written connection pool. Maybe there you will find other issues to help you decide.
Hope this helps!

"Get connected" for the dummies please!

Hello,
I bought this Palm TX more than a year ago and although my numerous efforts, still can't get connected to the internet. Would anybody tell me how to get connected in simple steps please?
Please note the following:
- My laptop uses Windows Vista and WiFi enabled
- I am connected to broadband internet through a normal (not wireless) router
- I don't have any home networks
Thank you
Post relates to: Palm TX

The TX is designed to connect to a wireless network. Wifi is built into it for this purpose, and is very easy to use! Wireless routers can be found for around $30 these days.
Since you have no wireless network, you are limited to connecting via BlueTooth through a cell phone, or via the Hotsync cable to your computer. The latter can be accomplished by purchasing a program called Softick PPP from softick.com. (You can also use BlueTooth to connect if your computer has BlueTooth built into it.)
I have connected mine through a cellphone and with my wireless network at home, but never via the cable. It just didn't make sense to me to use my TX when a real computer is 3' away...

My WiFi is connected but I can't get connected to internet on my Ipad

My Wifi is connected but I can't get connected to the internet on my Ipad.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Recently while using the iPad2, I clicked on some " UPDATE " and then I have lost the Internet connection . On several trials now I am
stuck up at a step which is asking PASSWORD to JOIN the Network. I am not at all recollecting the required PASSWORD .
Now how can I find out the original PW ? OR in its absence, how can I get connected to the Internet , and if
necessary, how can I create a NEW PASSWORD ?
WILL SOMEBODY KINDLY HELP ME SOON ? MANY THANKS IN ADVANCE !

How can I speed up the connection to the database?

I am running a JSP application with regular JavaBeans not EJB and connecting to the database through these beans. The connection is set to stay in memory as long as the bean is in session. However when I am running more than 7 sql statements seperatly the execution of the page slows down.
I have tried using connection pooling but doesn't help much.
I am not using the JDBC setting in JRUN, I am connecting through the jdbc.odbc drivers provided by the JDK. Basically coded the connection and the connection pool.
Is there something else that can be done to speed up the execution of the page?
Thanks in advance

Thank you all for your input I was trying to work this project to learn JSP so I am not looking at purchasing any drivers right now. That is the reason why I stuck to the JDBC-ODBC Bridge. Are there any other drivers available for MS SQL Servers that are free.
Jschell,
That suggests you are taxing the system. It could be >connections. It could also be network, cpu, bus, etc. It >could also be memory, if your app starts swapping to >the hard drive it will get substantially slower.How can i figure out which of the above (i.e. memory, cpu, connections, network) are causing the problem.
(Presumably you explicitly close your >ResultSets/Statements/Connections when you are >done with them.)You are right about that yes I am closing them at the end of the session, which I think should be after all of the SQL's get executed but I could be wrong it might be openeing a new connection for each SQL which inturn might be the reason for this whole problem. I will take a look into that.
Thank you all once again.

Can't connect to the database server from localhost

Hi,
I'm having a problem I hope you can help with please!
I recently installed mysql and phpmyadmin... I can access mysql perfectly from the command line, and can access it partially through phpmyadmin although there are some restrictions that I haven't figured out how to change yet (despite editing php.ini, configure.inc.php and others), but on the whole inside phpmyadmin I can see all the databases I've uploaded with the command line and all the users are there and can be edited. Unfortunately whenever I try to connect to a mysql database using a username and password that was created in phpmyadmin (or anywhere!), I get a 'cannot connect to the database server error'. I've checked and rechecked the username, the passwords, the database names and the host names a thousand times but nothing I change is working.
Is there a special prefix my mac could be adding to the database, usernames or host names?
Thanks!

Okay, don't worry!
I finally figured it out...
it needed to be 127.0.0.1 rather than localhost!

I am trying to setup my ipad 2 but I can't get back to the wi-fi connections section. How do I get there, nothing is working.

I am trying to setup my ipad 2 but I can't get back to the wi-fi connections section. How do I get there, nothing is working.

The Wi-Fi connections section is in Settings > Wi-Fi
If the home screen is not visible tap the Home button, the button on the front of your iPad that has the rounded square in it. Once you reach the Home screen swipe through the screen of apps until you find the Settings app. Tap Settings and go to Wi-Fi.
If your iPad is completely non responsive, try a restart.
Press and hold the Home button and the Sleep button simultaneously ignoring the red slider. Keep holding until the Aple logo appears and your iPad will restart.
The sleep button is on the side of your iPad on the side opposite from the Home button.

Hi, I’ve recently bought an iPad2 and can’t get connected with AppStore or iTunes, when I tap on these icons a grey page pops up saying is loading but never opens the page, no failure message is displayed, it just keep saying is loading.
Apparently it is not an issue with wifi since Safari, You Tube and Maps work well, I’ve tried some of the tips, e.g. log off/on my Id, change password but no one worked.
Your help will be highly appreciated.
Thank you.
Luis.

Try a reset. Hold the Sleep and Home button down for about 10 seconds until you see the Apple logo. Ignore the red slider.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.
