Trouble starting Netca, Trouble connecting to database
Hello All. I am trying to connect to a remote installation of Oracle XE and using the Enterprise Manager. It gives me a 'cannot parse ...' error when I manually type the db details. netca will not start on my machine to create a tnsnames.ora entry. Any ideas? TIA
Howdys, I am actually not getting any error at all. I click on the link and nothing comes up. I am using windows Vista. Is there a Netca log file I can view that might give clues? Newbie out.

Trouble connect MySql database on cluster
Dear Friends
I am trying to connect the MySql database on our cluster which have ROCKS cluster ebvironment on it. My code is just a test code to connect to the "test" database and i got fallowing exception
Exception: Data source rejected establishment of connection, message from server: "Host 'chemdynm.chem.ttu.edu' is not allowed to connect to this MySQL server"
Can anybody help me on this problem.My test code is as fallows
Thanks
Nav
import java.sql.*;
public class dbtest
public static void main(String[] args)
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql://chemdynm.chem.ttu.edu/test",
"root", "secret");
if(!con.isClosed())
System.out.println("Successfully connected to " +
"MySQL server using TCP/IP...");
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {
System.out.println("here is the problem " +e);Read the MySQL documentation about how to set up permissions. Not only do you have to declare permissions for each user ID, you also have to declare permissions for the hosts they may connect from. This is nothing to do with Java or JDBC.

OMS doesn't start - can't connect to database
Hi all,
My dev/test environment won't start OMS anymore. This really has us stopped in our tracks...
It will start the WebTier, but OMS won't come up:
[oracle@ora-emcc log]$ $OMS_HOME/bin/emctl status oms

Copyright (c) 1996, 2012 Oracle Corporation. All rights reserved.
WebTier is Up
Oracle Management Server is not functioning because of the following reason:
Failed to connect to repository database. OMS will be automatically restarted once it identifies that database and listener are up.
Trying to check oms details results in an error as well:

Any suggestions will be much appreciated.
EdHi all,
Many thanks for responding. I have opened an SR with Oracle 24 days ago. However, I just noticed I haven't heard from them for 13 days!
Must ping them to see what's happening...
I will check out your suggestions. The db and the listener are all fine and up anyway.
After looking in a lot of logfiles (and uploading them to the SR), it looks as if it could have to do with credentials in a wallet:
[oracle@ora-emcc log]$ cat secure.log

I will ping Oracle Support again (it's now with the security team) and see what the feedback is.

MySQL Database Connection (two databases at the same time)
I have never had to open more than one MySQL database from within the same website before, but I do now. The website I have is designed where all the content comes from within the main database. I am building an Inventory system that I want within it's own database, in the event I would ever need to move the application to another server or something, I don't want this data residing in the main database.
Currently, I open the database connection from within a file called "common.php" that resides in a directory called "lib" that can be accessed from the root directory. Below is the proposed code that would be placed within the "common.php" file:
// Define Database Variables
$dbserver = "127.0.0.1";
$dbuser = array('clevelan_user1', 'clevelan_user2');
$dbpass = array('P@ssw0rd', 'P@ssw0rd2');
$dbname = array('clevelan_database1', 'clevelan_database2');
// Start Session
session_start();
// Connect to Databases
connectdb($dbserver, $dbuser[0], $dbpass[0], $dbname[0]);
connectdb2($dbserver, $dbuser[1], $dbpass[1], $dbname[1]);
// Database 1 Connection
function connectdb($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db
global $connection;
$connection = @mysql_connect($dbserver, $dbuser, $dbpass) or die ("could not connect to server");
$db = @mysql_select_db($dbname, $connection) or die ("could not select databsase");
return $connection;
// Database 2 Connection
function connectdb2($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db
global $connection2;
$connection2 = @mysql_connect($dbserver, $dbuser, $dbpass) or die ("could not connect to server");
$db2 = @mysql_select_db($dbname, $connection2) or die ("could not select databsase");
return $connection2;
//End of Code Within the "common.php"
From within any page of the website, I want to access both connections by placing an include at the top of each page:
include_once("lib/common.php");
Currently, when I run the code above, any page within the website (the home page) provides error messages with regards to database connectivity (the pages are looking for there content from within the second database. It's as if the second database is the only database seen by the website.
I need help figuring out how I can have two MySQL databases open at the same time (the second database will only be open for short periods of time and then closed). But the main database is always open.Create one project using one copy of the exact tables.
create 2 different sessions.xml files each pointing to the same project. Set the login information in the sessions.xml files.
That should work fine.

Trouble connecting to remote oracle database
Hi,
i'm having trouble connecting to an oracle database (Release 9.2.0.6.0) using the ojdbc14.jar from the oracle website. Can anybody spot the problems that i need to sort out to get it working? Code and error stack below.
Thanks,

Hi,
We've got an ASA9 database that started causing us some trouble yesterday. It appears to not allow any connections to be made to it. Doesn't give any return messages, it just hangs at the client level and never does anything. The service window looks normal. Says the server is started normally, as well as the sharedmemory link, namedpipes link and TCPIP link. Starts on the port and says that it is now accepting requests. Try to connect through our application, scjview, dbisql, dbvalid, etc. all just hang with no response. Go to stop the service, and it just hangs as well. Have to kill all of the processes.
Had IT get me the backup, and it had the same problem. Had to go back 3 days to get a backup that would actually start and allow connections. I ended up translating the log and applying the sql to the last good backup in order to get us running again. Ran dbvalid against the database and nothing was found to be wrong.
I'm concerned that there is something else going on. Has anyone seen anything similar? Any thoughts on what the issue could be?
Thanks!
JohnHi John,
Assuming you still have a copy of the database that hangs, could you try starting it with request level logging enabled?
dbsrv9 -z -zr ALL -zo C:\path\to\file.txt database.db
As well as connecting with a client log:
dbisql -c "UID=DBA;PWD=sql;ENG=database;LOG=C:\path\to\file2.txt"
Which operating system are you running the server on?
Thanks,

I'm having trouble connecting my iphone to my itunes on my computer
So for christmas I got an iPhone and currently, I'm having trouble connecting my iPhone to my iTunes on my computer. If I get on my computer and open my iTunes, I can use it perfectly fine but once I tried to connect my phone to it, it told me the software needed to be updated before it would work with my phone. I went to the website and tried downloading the updated version 10 times but every time it told me it couldn't connect with an apple device or something. So then I tried just going to my downloads and stuff and moving the actual song straight to my phone but it would always tell me my device has ended or has been disconnected. All I'm trying to do is move some songs onto my phone from my computer. They weren't purchased straight from iTunes so it's not showung up in my "purchased" on my phone. (I think I got them from amazon and some are cds that I my computer that I got years ago. Maybe thats why they don't show up in the purchased?) Anyway, how can I fix this? I have a windows computer if that can help at all. Thanks!!!
Also, I just opened my iTunes on my computer then plugged my phone to the computer and a box popped up saying "This iPhone cannot be used because the Apple Mobile Device is not started"
I have no idea what that means.
I don't have that option on the side that says what device is connected so I can't sync or anything. -
I'm having trouble connecting to apps, itunes store, internet on my iPhone 5 running iOS 7.0.4. I am currently connected to a perfectly running WiFI connection. This just started happening today (2/19/14)! Why am I not able to connect anything? I've tried ALL the fixes suggested. HELP!!!!!!!!! BTW, I know my Wi-Fi connection is good because I'm using it on my desktop and other people in my office are also connected on their iPhones and desktops. Again, HELP!!!!
You may not really be connected to your WiFi network.
Your router may not have given your iPhone a valid IP address. Go to Settings > Wifi > your network name and touch the "i" to the right to see the network details. If the IP address starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Next, reset network settings on your iPhone (Settings > General > Reset > Reset network settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
If you need more help please give more details on your network, i.e., your router make, model and version, the wifi security being used (WEP, WPA, WPA2), etc. -
Having trouble connecting column to column using niSwitch on a PXI 2530
Having trouble connecting column to column using niSwitch vi on a PXI 2530 matrix module. I have configured my switch using Switch Executive, have identified aliases, and verified routes and route groups. When I use LabVIEW to connect column to column I get an error reading "cannot find connection between c0 and c1". c0 and c1 are example columns I want to connect. Any help is appreciated.
You can find NISE VIs in the function pallete in LV if you have installed LabVIEW support when you installed NISE (this is selected by default in the installer if you had LV installed before installing NISE).
Also, choose between niSwitch and NISE based on your need - if all you ever do is connect two channels in your application, then configuring a NISE virtual device is probably an overkill (and so is using a switch in this case:-) . However, if you are going to manage multiple routes, then using NISE configuration will let you create named routes and route groups, which you can then invoke (connect/disconnect) in your application and have the configuration part managed outside your application. The code would then concentrate solely on establishing a necessary connection(s) via connecting a route or a route group, while if you were to use niSwitch for this purpose, you would have to keep the logic of connecting inside your application, together with the list of channels that need to be connected.
Start with using NISE, and see if you like it.

Hi All, hope you can help, why do I have trouble connecting to free wi fi, especially at McDonald?
Hi All, can someone help please. Having trouble connecting my iPad to free wi if at caravan parks and also at McDonald, I have no such problem connecting my laptop. Thank you.
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 drooping 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

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
Wi-Fi or Bluetooth settings grayed out or dim

Trouble connecting Zen V Plus (4
I've been having trouble connecting my Zen V Plus to the computer. When I connect it I manage to transfer maybe 0-20 songs if I'm quick (I'm using WMP .0.572.545), but then everything freezes. I have to plug out the player before the computer and the player starts responding. If i reconnect it quickly I manage to transfer 0-20 additional songs.
The player's firmware is .0.03e, and I've got Windows XP Pro with Service Pack 2 installed. I've tried using both WMP and MediaSource, but I have the same problem. I've even tried formatting the hd and installing a fresh XP Pro (with SP2), but I get the same result.
Does anyone have an idea of what I can do?
Can this be an error with the player?
Is this a good enough reason for me to get a new player?I have the same product and hooked the player up before download, and now my computer won't recognize it being pluged in, how do i fix it, anybody?

I am having trouble connecting to my in-home internet via my wireless router. The IPad says I'm connected to the router, but I am unable to receive email, Facebook and Safari. I run through Charter Cable. This only occurs on my IPad. My desktop works fine.
Although it may ultimately be necessary to perform a Factory Default Reset on the AirPort Extreme and start over with a new configution, we can first try to see if things will work with the existing settings on the device.
Push the reset button (if present) on the cable modem
Power off the modem by pulling the power cable
Remove the internal battery from the modem (if easily accessible)
Power off the AirPort Extreme and every other device on the network....order is not important
Wait at least 20 minutes....longer is better
Re-install the battery in the modem if it was removed previously
Make sure that the Ethernet cable from the modem is connected to the WAN port (circle of dots icon) on the AirPort Extreme
Power up the modem and let it run 4-5 minutes buy itself
Power up the AirPort Extreme and let it run 4-5 minutes
Then power up each other network device one at a time about a minute apart
Check for a good Internet connection on the network with all devices
If still no luck, you will need to perfom a Factory Default Reset on the AirPort Extreme as follows:
Pull the power plug from the back of the AirPort Extreme
Hold in the reset button and keep holding it another 8-10 seconds while you simultaneously plug the power back in to the AirPort Extreme
Release the reset button and allow 25-30 seconds for the AirPort Extreme to restart to a slow, blinking amber light
Then open AirPort Utility end reconfigure the AirPort Express again. -
Trouble accessing the database
Hi, am new to java and I am having trouble accessing my database. I have the following code
import java.sql.Connection;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.CallableStatement;
import java.sql.ResultSet;
private static boolean verifyInDB(String username, String password){
boolean allow = false;
try {
Driver d =(Driver)Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
conn = DriverManager.getConnection("jdbc:odbc:SITSDB");
queryStr = "SELECT username,\"password\" FROM WebAppUsers WHERE username=" + "'" + username + "'" + "AND password=" + "'"+ password + "'" + "AND archive = 'no'";
myQuery = conn.prepareCall(queryStr);
//myQuery.setString(1, username);
//myQuery.setString(2, password);
rs = myQuery.executeQuery();
if(rs.next())
allow = true;
catch (Exception e) {
System.out.println("Login::verifyInDB: Error Getting Connection: " + e.toString());
System.out.println("Login::verifyInDB: QUERY: " + queryStr);
e.printStackTrace();
finally{closeConn();}
return allow;
I'm almost positive the code it is right however I get an error trying to connect to the database
Login::verifyInDB: Error Getting Connection: java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'WebAppUsers'.
Login::verifyInDB: QUERY: SELECT username,"password" FROM WebAppUsers WHERE username='akabeera'AND password='avenash'AND archive = 'no'

ssj_100To be clear when you say the command works in query analyzer. Is this the exact string that you are running in query analyzer?
SELECT username,"password" FROM WebAppUsers WHERE username='akabeera'AND password='avenash'AND archive = 'no'This exact string (the SELECT) looks syntactically incorrect to me, but that doesn't mean your database SQL parser cannot handle it I guess (lack of spaces between quotes keywords), and I'm not sure about the double quotes, but I'm kind of an Oracle guy and all of this could be OK, it just seems messy if nothing else.
I would recommend using first, a type 4 driver if at all possible (not the JDBC/ODBC bridge), and second To avoid much of this messiness, you should whenever possible use a PreparedStatement rather then Statement for this type (and most types) of queries.
