I can not establish a connection to Oracle with an application in win 7

I have an application in VB6 that connects to an Oracle Database 10g with Oracle native ole db but win7 can not make the connection with a standard user, only makes the connection to a user with administrator permissions. The error that shows the application's rubbish eg @, H, etc.. only rare characters.

Did you try adding the user in administrator group and running your programm, even doing so is giving you same error?
Can you connect to sqlplus as non admin user and fire sql commands
start>run>sqlplus (if you have more than one installation, run from your oracle_home/bin)
connect as the non admin user and run sql
if the "User Account Control is enabled", try disabling

It sounds as though a script on the site, or an advertisement, is not working quite right...
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
(You also can clear Firefox's cache completely using:
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now")
(2) Remove the site's cookies using either of these. Save any pending work first.
While viewing a page on the site:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
Then try reloading the page. Does that help?

IO Error: The Network Adapter could not establish the connection in oracle

Hi experts,
I have oracle developer days installed in my vitrual box machine. The connection to oracle datatase (11.2.0.2) contained in the oracle developer days was working fine via sql developer. I use eclipse to write some java programs to connect the database. However, somehow, I cannot connect the database via sql deveoper anymore. This is the error I got when I tried to connect it via basic connection type:
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Can anybody shed a light on this issue please. Thanks a lot in advance.

I, too, am running Oracle Developer Days inside VirtualBox.
On which system is SQL Developer installed?
The post errors indicate an OS/networking issue.
when was last time all worked without error?
what changed since then?
How do I ask a question on the forums?

Can not establish a connection with SQL

hey all,
i was trying to start with JDBC ,but i spent two days trying to establish a connection with SQL.
can anybody help me please, the problem is about the url string and driver name.
am completely lost with these stuff :(
thnx in advance,

am using Microsoft SQL server 2005, but i don`t know how to get or setup driver correctly.
please explain how.
Are you specifically using "localhost" as the server name and thus the database is on your client box? If not then SQL Server must be configured to accept such traffic before it will work.
Other than that the most common problems are
1. The port is wrong. It is either 1433 or 1434.
2. The server name(or IP) is not visible from client computer. Nothing you do in java nor MS SQL Server will fix this.
Printing the stack trace and posting it here provides more information for us to help.

HT5663 why I can not open an icloud email attachment with iworks application in icloud directly?

Hi,
I like this iwork solution in icloud, but the integrity might be developed more. If I got an email to my icloud inbox, I can not open it with iworks application but it will be downloaded instead. It would be very useful to be able to open an attachment onsite, using one of the iworks app.
thanks

Can not establish L2TP connection to Mac Server via VPN

Hi,
I am asking for some help on this VPN Problem:
since yesterday I have a new Mac mini Server running OS X 10.9.3 and Server Software 3.1.2 - my goal is to reach some deivces in my home network from outside, mainly with the iPhone or iPad.
Dyn.org
I registered with Dyn.com a hostname using my outside IP Address. Server Type: Host with IP Address and used the IP Address presented to me in the stup wizard. This one is shown as active and when I ping or Lookup the Host Name it is responding - so I think I am fine here.
Mac Mini Server
Next I have setup a user on the server who can use VPN. Next I have setup the VPN service with L2TP, using the Host name von dyn.org, a nice shared secret, IP range 10.0.1.190 to 10.0.1.199, DNS 10.0.1.1, no routs.
I exported this as config file to my iPhone.
The VPN Protocol in the Server says, it is listening for connections.
When I turn on VPN on the iPhone it replies always L2TP-VPN-Server has not answered.
AirPort Extreme
The AirPort Extreme is configured by the Server with Ports 500, 1701, 4500 and the Mac Server 10.0.1.26 as Privat IP Address.
The Internet Tab shows Router and DNS as 192.168.211.1 and IPv4 Address as 192.168.211.109
I actually do not understand why I have a 192.168.xxx.xxx DNS and router entry while I have the Privat Network on 10.0.1.xxx
The Protocol for VPN just says nothing at all, besides that it is listening. I guess something is blocking the connection to the server.
By looking at my above configutation - what am I doing wrong? Why do I get this L2TP-VPN-Server error message? I changed the password for the user to be sure I am not miss spelling it. Did not help.
Any idea?
Thank you for your support!
Regards
Klaus-Martin

According to your IP addresses you listed, you might have two devices that are trying to create a NATed network (one in the 10.0.0.0/8 and 192.168.0.0/16 networks). Can you list what devices you have between your server and the Internet?
I'm going to take a guess that you have a router/modem prodived by your ISP, and this is going to give you a 192.168.211.0/24 network (since it set up as a router to provide its own network). You then plugged an Airport into this router and configured it to set up its own wireless network on its own subnet (10.0.1.0/24). The server is on this network, sees the Airport (and lets you configure it). So while your hostname points to your external address (which is good), it's just that external address is the WAN side of the modem/router and not the Airport. I think your network is set up like this: Internet --> ISP modem --> Airport --> Server. If this is the case, you need to set up the ISP modem/router to port forward L2TP ports to your Airport (which in turn, port forward to your server). Or you could set your ISP modem/router into bridge mode and have the Airport dial the connection to the ISP (more complicated).
Have you tried VPN from the local network, say put the phone on wifi and make sure that works? This would be a quick test to make sure the phone and server are set up properly.
Also, have you tried port scanning your host from a computer outside your network, like from an iPhone on celluar? That would help you determine if you have routing configured properly for the L2TP VPN ports.

Hi,
according to the message, the database is not accessible. This can be because the database is down or the database connect information points e.g. to a wrong port

Jdbc. The Network Adapter could not establish the connection. Help Please!!

I've found several responses over this issue, but none works for me.
I'm trying to setup a simple jdbc connection from a simple program.
Platform:
Fedora Core 4 (FC4) on AMD 64 bits
Java 1.4.2_04 (64 bits)
ORacle 10g or Oracle 9.2.0.4 (none works);
Tips:
- I can't connect to a remote server, nor to a local server
- I can connect using SQLplus
- TNSPing works fine
- Listener it's up
- my connection string is jdbc:oracle:thin:user/name@host:port:sid
- Also try jdbc:oracle:thin:user/name@//host:port/sid
- I'v tryied with classes12.jar, odbj14.jar
- my hostname it's ok.
I've monitored ip traffic on remote computer. While using TNSPING I detect activity. While using jdbc, no.
Please, any idea??

Thanks for your reply.
To your questions:
- I´v tried both IP, host, and even host.domain
- I can connect from remote workstation using toad, and from local using sqlplus.
- I can´t connect via jdbc.
Folowing:
A) my sample code
B) the stack trace
C) the listener status (from my 9i server. Also tryied another servr with 10g)
when I call this program, I´ve tried severl connection strings:
jdbc:oracle:thin:user/pass@sdd51:1521:ebf
jdbc:oracle:thin:user/pass@:sdd51.sdd.com.ar:1521:ebf
jdbc:oracle:thin:user/pass@:10.10.10.51:1521:ebf
also try the other sintax:
jdbc:oracle:thin:user/pass@//sdd51:1521/ebf
In the classpath, I´tryied:
clasess12.jar
ojdbc14.jar
nls_charset12.jar
thanks

What should I do? And when the server starts and I run the application, I get the following error:

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
Can anybody help me...?????

Can you try writing a testcase that allows you to connect to the database by going through JDBC ?

If it worked yesterday, but not today, that proabably means you turned off your computer between then and now.
I suspect you set up some classpath term using say a dos window that when you turned off your computer, went away.
You need to put the classpath in some configuration file such as <start><control panel><admin tools><data sources odbc>,
or add information to your tnsnames file, or add an item to your computer's PATH.

I have changed Oracle drivers and tried many different configurations, with no

Hi. This is definitely an oracle-only problem, so you should simplify the problem
down to a small standalone program using the oracle thin driver to make a connection.
Once you get this to work, weblogic will also be able to do it. Make sure that
when you try to have weblogic succeed after you can do it with oracle code only,
that the driver you used to succeed with, is ahead of any weblogic jars in
the server classpath. Note that we ship a classes12.zip in our packaging, but
Oracle has since released a newer one (with the same name!) that has some bugs
fixed. Make sure the later one is the one the JVM will pick up.

JDBC Error - The Network Adapter could not establish the connection

Hi all,
I appreciate if anyone could help me out with my issue. I wrote simple java code on win 2000 to test whether I will be able to access Oracle 8i DB resided at some xxx.xxx.xxx.xxx machine within the network.
The code is:
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@111.111.11.11:1526:DBinstance","user","password");
The fist line here is executing and the problem is with second line of code. After executing this application from my DOS window, I am getting error:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection

I have installed Oracle client, where I can access the same database using SQL * Plus, but why I am unable to access the database from a Java Application? Do I need any web/application server to access it?
Any suggestions please?
Thanks,

I am sorry guys, I was using the port number as 1526, where I need to use 1521...

Iweb not establishing a connection

I am trying to upload my website to a ftp that has worked without a problem in the past. I keep getting a message that says it can not establish a connection. I have verified the information for the ftp and it is all correct. My hosting company has verified that the account is working. Why won't iWeb establish a connection if all the information is correct, and the hosting site is working?

If you follow Ethmoid's suggestion and find that the problem lies with iWeb and it's builtin FTP client you can try the following:
delete the iWeb preference files, com.apple.iWeb.plist and com.apple.iWeb.plist.lockfile, that resides in your Home() /Library/Preferences folder.
go to your Home()/Library/Caches/com.apple.iWeb folder and delete its contents.
Click to view full size
launch iWeb and try again.
If that does'nt work you may have to continue to use Cyberduck to upload your website files to your server. This tutorial may help in that situation: iW01 - Uploading Only Those Newly Published or Edited Files When Using a 3rd Party FTP Client

Connection Pooling : Network Adapter could not establish the connection

Hi,
We have a client-server application wherein the server has a pooled connection to an Oracle 10i database. The application is developed in Java and we are using Oracle OracleConnectionCacheImpl API to manage the connection pooling( DYNAMIC pooling with a pool size of 5 and we are using ojdbc14.jar)
On certain occasions when activity is extremely high, the server attemtps to retrieve around 2 million datasets/records. The connection pool runs out of connections and we get the following error :

This is happens in Production and despite our exhaustive efforts,we have been unable to reproduce it in our Testing environment so far.
A large number of login attempts are seen in the Oracle login monitoring table, around 50,000 but we dont think that should be an issue. At the time, when this problem occurs, there are other processes making connection to the DB without any issues. Also, after sometime, the connection is restored and no exceptions are thrown.
Any insight into how we could simulate,resolve or monitor this issue would be greatly appreciated.
Thanks,

Hi. This a long-known issue, and is caused by the DBMS listener's incoming
request buffer becoming overloaded by many simultaneous connection
requests. It will fail some of them. I have seen this with a simple java
program that calls Driver.connect() identically 20 times in a tight loop.
Some of the calls will fail in this way, while others will succeed. The
solution BEA's pool has, is to have a delay option to have the thread
sleep a bit (half-second to a secod or so) between successive connection
requests. After that, don't close connections until they're broken. Keep
them and re-use them.

Can not establish connection Oracle DB

Hi PI Gurus,
We have a sender JDBC CC, its working absolutely fine in PI dev.
when I check this CC in PI Qality it is giving me error as:
Error during database connection to the database URL 'jdbc:oracle:thin:@204.145.15.141:1521:PERM' using the JDBC driver 'oracle.jdbc.driver.Oracledriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Can not establish connection:: SAPClassNotFoundException: oracle.jdbc.driver.Oracledriver'
It clearly says that driver is not installed, thats why connection is not getting established. Our BASIS team installed the drivers twice copied from Dev systems, still the same error is coming.
Can anyone throw some light on this, is any problem with the version?
Thanks,
Krishna

Hi Krishna,
Can you check two things:
1. whether the host name of the jdbc server u are tryin to access is present in the PI Quality system hosts file
2. Whether connectivity port is correctly opened with the jdbc server, i.e connectivity exists and is tested.
Regards,
Souvik
