JDeveloper - Oracle 8i Lite Connection Problem

I am trying to connect to Oracle 8i Lite database on my local machine (NT as the OS) from JDeveloper 3.1.1.2, I am getting "Network adapter could not establish connection" error. I can not even do Net8 Easy Config as I have no idea what the SID name is as 8i Lite installation did not ask for any SID name and it just created the polite databse (which works fine from ODBC).
What is the default SID name for 8i Lite ?
How to fix this probelm. Any help is greatly appreciated. VR.

There is some more work you need to do to make JDeveloper work with Oracle Lite. Details are in an earlier response to a similar problem:

Oracle 8i Lite connection problem

I'm trying to make connection with Oracle 8i Lite native jdbc driver. I'm getting error "Unable to find driver oracle.lite.poljdbc.POLJDBCDriver" when pressing Test button.
olite40.jar is in IDEClassPath in jdeveloper.ini and Oracle 8i Lite is in Default Project Libraries.
What I've missed?

If you have added the Olite40.jar file to the IDE_CLASSPATH setting in the jdeveloper.ini file, make sure you restarted JDeveloper after editing the ini file.
Also, make sure you specity 'Olite40.jar' not 'olite40.jar' (watch the case of the archive file name).

How to solve Oracle SQL Developer connection problem ?

Folks,
Hello. I am using Oracle Database 11gR1. The Database Control Console https://localhost.localdomain:1158/em works correctly. I can create a Database and a table successfully.
My OS is Linux and connects to internet successfully.
In order to run SQL statements. we need to use Oracle SQL Developer. I connect Oracle SQL Developer in the following way:
Connection Name: DB1 (this is my database name as well)
Username: SYS (this is the user name I used to login to the Console)
Password: SYS (this the password used to login to the Console)
Connection Type: Basic
Host Name: localhost
Port: 1158
SID: DB1 (this is created during installing the Database)
But the error message comes up: "Status: Failure - IO exception Connection Reset."
Can any folk tell me how to solve Oracle SQL Developer connection problem ?

Can any folk tell me how to solve Oracle SQL Developer connection problem ?username: sys
password: enter_your_correct_password given at the time of oracle installation
role: select sysdba if you would connect as sysdba else select normal for users other than sys
hostname: enter your oracle server hostname or ip address eg:- 192.168.11.12
to find the hostname open terminal/command prompt in oracle installed machine
type ---> hostname
type ---->ping hostname
you can find the ipaddress of the server
port number: 1521 (default) ----> i guess , else check the port number in the tnsnames.ora file under your ORACLE_HOME/network/admin folder
SID: DB1
try it
Good Luck

Oracle 9i Lite Installation Problems

Hello, I'm installing Oracle 9i Lite Version over Windows XP. When I'm connecting the mobile server (like an apache server's module) to the repository, I write in my browser:
"http://<mobile_server_name>:<port_number>/webtogo/startup"
and the response of the browser is: "The requested URL was not found on this server". Someone knows, what's the problem?. What's the mobile server name and its port number?.
Thank you.

Jorge,
You can check the tnsnames.ora file for the Mobile Server name and port number. Once you find the correct server and port information, please point your browser to:
http://<Mobile Server>:<port>/webtogo
for the Web-to-Go home or
http://<Mobile Server>:<port>/webtogo/setup
for the client download page.
Please let me know if you have additional questions.

Oracle 8i Lite Synchronizatoin Problem--Very Crucial and Urgent

Currently,we are using Oracle 8i lite Version Release 4.0.1 in
our project.
Following is the problem we are facing during Web-To-Go
Synchronization.
We have published about 200 snapshots of tables on the Web-to-go
server.
After Installing the Web-to-Go Client,
the first time we went Offline, both the webtogo.odb and the
user odb got downloaded to the client's machine.
the size of user odb was about 10.7 MB containing 200
snapshots,without any data and the application about 15 MB.
We checked up the odb using plus80 and verified that all the
tables have been created(200 snapshots+200 snapshot logs).
Once we went Online , a memory/application error (illegal
operation,unable to access memory) was displayed.The m1 file
also remained in the client's machine.
Basically the synchronization fails from client to server.
Everytime the synchronization is fine,if the odb needs to be
created freshly,but once created and synchronized,the same error
is displayed.
We tried publishing with a reduced no of tables,and it went on
fine with both offline and online up to a size 8.28MB,with
about 152 tables.
An increase of even 10 KB by an addition of 2 more tables,gives
out the same error.
The limit on the no of snapshots is specified as 256 per refresh
group.
We are using only 200 as of now and that should be ok.
Please let us know the possible reasons for such kind of a
problem.
Let us know in case of any other clarification regarding the
problem.
Is there any limitation or requirement at the client site,w.rt
memory?
Pls Help
Meena.

Oracle 9i lite connection with a Java Client

Hi,
I would like to connect a Java Client developed using PersonalJava edition for PDA with an Oracle 9i lite version which is also on PDA.
I would like to know is it possible to connect such a client (Java) using some JDBC drivers on PDA.
if yes please do suggest a suitable driver and some input tips as to how to connect a GUI developed in Java directly to Oracle on PDA.
I am not too sure whether some web/application server is required in the whole setup.
because in N-Tier Architecture we have a middle layer of Application /Web servers in between a client screen(usually a Browser) and Database.
but I am not aware weather it is possible to directly connect Java Swing or Client application as I mentioned above developed using Personal edition with a database using only some driver software but no other middle ware component in between.i.e forming a 2 tier client server model.
please do let me know your valuable suggestions at [email protected]
thanks,
Ashish

I connect to the database through the same user that created those tables. Do I still need a public synonym ?

Oracle 8i Lite Login Problems

I have installed Oracle 8i Lite on my computer, which has Windows 98. But I have been unable to access the database after trying several combinations of usernames & passwords such as tiger/scott and system/manager, among others. I must be missing a step somewhere in this process. I'd greatly appreciate any suggestions.

What kind of webtogo do you try to install?
Have you installed a jre 1.1.8 or plus?
Is your database started?
If yes, you try to put system and system 's password.

Oracle DOA/Application connection problem.

I am looking for some help with a problem we are having with a connection issue with DOA objects and Application objects. We have a number of programs that were written using Delphi (version 5) that contain DOA (Direct Oracle Access) objects and Application Objects. The problem seems to be the order in which the connections are made. We have created a test program that proves this for us.
Our environment is a Windows 2003 Server Standard x64 Edition SP2 with Oracle 10.2.0.3 installed. The processor is a dual core processor with 4 gbs of ram.
When we open Delphi, load the program connect the application (using the application object) and then connect with the DOA object there is no problem. There is 2 connections and the program runs fine.
Whenwe open Delphi, load the program, connect the DOA object and then connect the application object the server hangs. the hour glass displays and sits there. The memory associated with the oracle.exe process continues to get larger and larger (looking in task manager) then when it reaches 1, 386, 750KB approximately the Oracle database service ceases and the windows creats a dump file (oracle.exe.hdmp) the size of the memory allocated. The following trace file is created:

It appears the connection is trying to connect a second time. Does anyone know how to resolve this issue. Is there a configuration parameter to resolve this issue so the server does not lock up and then crash the database service.
Any help would be appreciated.

Did you install the Oracle Lite runtime on your WM5 device properly? What CAB file did you use? It seem like you didn't install the runtime on your device at all....

What changes should i make to overcome this problem.

"ora-12154 tns could not resolve the connect identifier specified"The problem is local to the Forms Home, probably in tnsnames.ora (seems that there are tabs in IMS entry name). Carefully check it.$ oerr ora 12154
12154, 00000, "TNS:could not resolve the connect identifier specified"
// *Cause: A connection to a database or other service was requested using
// a connect identifier, and the connect identifier specified could not
// be resolved into a connect descriptor using one of the naming methods
// configured. For example, if the type of connect identifier used was a
// net service name then the net service name could not be found in a
// naming method repository, or the repository could not be
// located or reached.
// *Action:
//   - If you are using local naming (TNSNAMES.ORA file):
//      - Make sure that "TNSNAMES" is listed as one of the values of the
//        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA)
//      - Verify that a TNSNAMES.ORA file exists and is in the proper
//        directory and is accessible.
//      - Check that the net service name used as the connect identifier
//        exists in the TNSNAMES.ORA file.
//      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
//        file. Look for unmatched parentheses or stray characters. Errors
//        in a TNSNAMES.ORA file may make it unusable.
//   - If you are using directory naming:
//      - Verify that "LDAP" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Verify that the LDAP directory server is up and that it is
//        accessible.
//      - Verify that the net service name or database name used as the
//        connect identifier is configured in the directory.
//      - Verify that the default context being used is correct by
//        specifying a fully qualified net service name or a full LDAP DN
//        as the connect identifier
//   - If you are using easy connect naming:
//      - Verify that "EZCONNECT" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Make sure the host, port and service name specified
//        are correct.
//      - Try enclosing the connect identifier in quote marks.

Oracle 11g XE Connectivity Problems

Hi to all and thanks for the attention !
Quick facts
OS : Microsoft Server 2008 R2 (x64)
Oracle Version : 11g XE (x32)
Database name : XE
I've been fighting over with providers for a whole day and I can't seem to make this work out,
I have an application(Web, on a IIS 7) that connects to a schema, the connection uses a Oracle Provider For OleDB, well at first I was getting a "Provider not registered" error, that was easy I only had to make the app run on x32 and puf the error changed, so I quickly set up the Data Source ( with the data source manager located in WOW64 ) with a oracle ole db provider, no problems, I can click on it, it will ask me for a user/password and when I click test connection I works just like I would expect it to work, now back to the application, when i set the connection string up, I get a error from the app : ORA-12154 TNS:could not resolve the connect identifier specified. So went up and tried making a udl ( invoking again the x32 ), same error ORA-12154 so I started digging and so far so good what I got is, "try tnsping <instance_Name>", did it, and got an OK (40ms) (though I had to navigate to bin folder, which was not explained in the posts, perhaps this means something ?) and also registered the oraoledb11.dll with regsvr32
Oh ! And I can connect to the database with sqldeveloper
I know really little of Oracle, any thoughts ?
Thanks again !

ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 NEVER involves the listener, the database itself or anything on the DB Server.
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
TNS-03505 is thrown by tnsping & is same error as ORA-12154 thrown by sqlplus or others.
The lookup operation fails because the name provided can NOT be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.
So post the content of the sqlnet.ora file.

Oracle/ SQL Developer connection problem.

I have installed Oracle 11 g and SQL Developer, When I open SQL Developer and try to make a new connection ( I name the connection, put a user name in, put my password in), I click on "Test" and I get this error:
Status: Failure - Test failed: Listener refused the connection with the followong error:ORA-12505, TNS: listener does not currently know of SID given in connect descriptor The connection descroptor used by the client was:localhost:1521:ex
Can anyone explain this to me and help me resolve this issue I am having?
Thank you in advance for your help

p.s. I have also tried the user name: Scott and Password: Tiger

Windows 7 Home ... will have challenges at some point, as Oracle may not be completely compatible with Windows 7.
Aside from that, you may find firewall issues even if you are on the same machine, since the default connection from SQLDeveloper is to use the network (even loopback).

XE =

    (ADDRESS = (PROTOCOL = TCP)(HOST = FCC003L)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
)and you will note the XE on the left side of the equal sign (which is a network alias), and one XE in the (SERVICE_NAME = XE) line. On YOUR system, the XE should be replaced by whatever you called your database (often 'orcl'). REMEMBER THIS ALIAS;-) and also make note of the host that your entry uses. If your host name changes because of DHCP, you're hooped (for a while).
If the database is registered (shows up in the list), the next step is to make sure a userid is available. You could use 'system' (try to avoid using SYS since it is the master userid and if you mess that up, you mess up all your homework. In a production encvironment, every access to SYS will be audited.
So, let's create a userid called me with (in 11g case sensitive) password 'myself'. Make sure that user is allow to log in (create session) and create a table.

If it did not work, try dropping the "@XE" to see whether you can get in (using the bequeath connection) which is useful for troubleshooting but will not help with the traditional SQLDeveloper connection. If you get in without the @XE (or whatever your alias is) but not with it, most likely either your listener is not up or your firewall is blocking the access to the listener.

Oracle 11g XE connectivity problem

Hello,
I'm trying to setup a Virtual machine for test purposes using VMware Player.
I'm following Oracle® Database Express Edition Installation Guide 11g Release 2 (11.2) for Linux x86-64: http://download.oracle.com/docs/cd/E17781_01/install.112/e18802.pdf
As described there, I've installed Oracle Enterprise Linux 5 Update 2 from DVD V15099-01.zip(Enterprise-R5-U2-Server-x86_64-dvd.iso).
After that followed the instructions in the guide and installed the XE database... so far no errors or problems... while testing from local ssh session :)

But now when I try access this VM box from my windows box, from where I have ping and can open SSH connection, I get "Could not open connection to the host".
I've already disabled my windows firewall for the test - no good. Also SSH works over the network, so I don't think it's a firewall or network issue...maybe I'm missing something in listners configuration or some security setting somewhere?
I've created screenshot http://img846.imageshack.us/img846/2931/oraissue.jpg .
I'm looking forward to your suggestions, because I'm running out of ideas, I expected to be able to start this thing faster :)

Hello,
What sort of access? And ssh is working? putty? Using VM NAT, or bridged?
Yes, from my desktop windows to the VM's eth0 interface I could use SSH without any concerns. Yes, I've used PuTTY Client for SSH. For VM is bridged.
That's not relevant to accessing the VM, you'll need to open up ports in the VM host firewall. Port 8080 too if you want to access the Apex pages, along with opening port 1521 for the database listener.
Yes, you are right - had to stop firewall on my VM box... since this is a dummy sandbox I just stopped firewall
service iptables stop
chkconfig iptables off
After that SQL Developer Studio managed to open connection to the XE database on this VM box over the network. Thank you!
You've got all the listener endpoints, including the http 8080 but setting up a server on dhcp isn't optimal unless you have dynamic DNS to register the VM IP for name resolution. Unless a dos box $ ping oracle11xe or $ ping oracle11xe.localdomain from the Win box gets the correct IP address of the VM ...
Sorry I didn't get this one... Could you please give me more information.
I've configured VM(oracle11xe.localdomain) to use static IP address(NO DHCP, I'd like to avoid involving the DHCP Server in my network in this simple test). This leads to me being able to ping it from Win Box only via IP address, what problems may show up from this? My idea was to avoid having problems, if for example I started the VM box in very different environment(lets say another network) and it gets some other IP address, because I didn't knew how oracle XE will feel about the new IP?
Once again - Thank you. Original issue is solved!
