Bug - unable to create new connections on SQL Developer 4.0.0.13

Upgraded to SQL Developer 4.0 and we are unable to create new connections in the Connections pane on the left hand side.
Clciking the green plus button and right clicking Connections and 'New Connection' doesn't bring up the New Database Connection dialog box.

Sounds like an 'install' problem.
Can you extract the zip to a new directory and try again? You did extract v4 to a fresh directory, yes?

I'm unable to create a connection in SQL developer..it says I/O Exception, Network Adapter could not establish a connection...i provided the username and password which i used for SQL*Plus, which is working fine. And i gave the host as localhost. I don't know how to fill the connection name field..can anyone help me in connecting to the database...By the way I'm using Oracle 11g. Thankssssss

you could try to change the connection type to TNS and pick the database name available to you in the Network Alias drop-down list.

Unable to create TNS connection in SQL Developer

This is my first time install SQL Developer 1.5 on my computer and when I try to create a connection using TNS Connection Type to connect to Oracle database, I get this error message:
Status: Failure -lo exception: SO exception was generated.
Do you know how to resolve this error?
Thanks,
Lily

Hi Lily,
This error is due to a tns entry that is unusual/malformed.
Note that
1/sqldeveloper picks up tnsnames.[a variety of endings not just ora] rather than just tnsnames.ora .
2/We recently released 1.5.1[.54.40] is that the release you are using
Can you post the 'problem' tns entry with ip and service name replaced by a stub?
ie something like:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = my.machine)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = my_service_name)

Problems Creating Custom Connections In SQL Developer

I have the Auto-Generated Local Connections available in SQL Developer 3.2.20.09 Build MAIN-09.87, but cannot create my own connections. I've searched the forums, but haven't had an "AHA" moment.
I installed the 32-Bit Oracle 11gR2 and SQL Developer with JRE on my Windows x64 system because installing the x64 version of Oracle 11gR2 failed. This is for database classes I'm taking at the local community college.
Trying to create a connection with OS Authentication:
Connection Name: PaulK
Connection type: Basic
Role: default
Hostname: localhost
Port: 1521
SID: orcl
and clicking Test returns Status: Failure - Test failed: The Network Adapter could not establish the connection
When I run lsnrctl services, I get

Establish new connection in SQL developer

hi,
i am trying to establish new connection in sql developer, i m just new in orcale and installed 10g , from where i can get all the required information for new connection like HOSTNAME, port , sid etc
pls someone can help me on this

Depends. All this was presented to you when installing. If you didn't wrote anything down...
If you accepted all defaults, it still depends on your DB version (which?).

How create new user in sql developer?

so i tried creating a new user in SQL developer, under the worksheet section, for a 12c database
create user Hares1
identified by book;
but I get this error
SQL Error: ORA-65096: invalid common user or role name
Sorry I know this is a generalized question. I only learned how to actually connect today - any help of a next step would be appreciated.

so i tried creating a new user in SQL developer, under the worksheet section, for a 12c database
create user Hares1
identified by book;
but I get this error
SQL Error: ORA-65096: invalid common user or role name
The 'next step' is RTFM. Sorry but for 12c multitenant you simply MUST read the documentation about the new multitenant architecture.
Your 'problem' is not creating a user with sql developer - it is how to create users in 12c.
See my extended comments and reply in this thread (and several other threads I reference there) which addresses your exact problem
12c: ORA-65049: creation of local user or role is not allowed in CDB$ROOT
http://www.oracle.com/pls/db121/homepage
I suggest you first read chapters 17 and 18 of the Concepts doc about the new multitenant architecture of 12c.
http://docs.oracle.com/cd/E16655_01/server.121/e17633/part_consol.htm#CHDGDBHJ
The 'Common Users in a CDB section answers your question
>
The name of every user-created common user must begin with the characters c## or C##. (Oracle-supplied common user names do not have this restriction.)
>
There are two types of users in 12c: common and local. You need to understand the difference between them.
Until you read those doc chapters you won't understand these terms: common user, local user, CDB, PDB, root container, and many others.
As I said in that other thread:
You will NOT be successful working with 12c unless you have read and understand the new multitenant architecture that it uses. There are very simple things (connecting, startup/shutdown, creation of users, grants to users, etc) that just don't work the same old way anymore.
If you try to just 'plow through it' without reading about it you will likely get an exception that you won't understand and it will likely use a term (CDB$ROOT) that you won't understand. Then you will hunt all over (or worse, ask in the forums) to find out about that term.
Yes - I know how adverse some people are to RTFM replies. But for 12c multitenant it is mandatory to read the docs no matter how expert you may be in previous Oracle versions.

SAPGUI Java 7.20 Rev 1 for Mac - unable to create new connections

Greetings,
I am on Snow Leopard, I just installed SAPGUI 7.20 Rev 1. When I try to create a new connection, the "System" tab has a Red X and I am unable to type anything into it.
Also, when I change the Description, the "Save" and "Save As" buttons are still greyed out and I am unable to click them.
I tried going through the documentation and made sure that I have Apple's latest Java updates etc.
Obviously I am doing something wrong somewhere. If someone will point me in the right direction I would be much obliged.
Thank you and cheers
Mohan

Hello,
you might want to read chapters "7. Administration" and "9.1 Connection Strings" of the manual coming with the SAP GUI for Java installation.
In case you want to reuse the configuration of SAP GUI for Windows, there are conversion scripts available on the [SAP GUI family page|SAP GUI Family] or directly [here|SAP GUI Family?rid=/library/uuid/c00de625-24e8-2d10-67b3-f79dad1a27c7].
Best regards
Rolf-Martin
P.S. The latest version currently available is SAP GUI for Java 7.20 rev 5

Unable to create new connection using SAP Business One

Hi all,
I am unable to make a connection using the new SAP Business One connetion provided with the 8.8 release of SAP Business One Crystal Report Integration Package.
There are no Companies available to select from. When I try to manually type in the company name, the logon fails. If I then press "Cancel", I get a message that Crystal reports encountered a problem and needs to close. The details of the error refers to the following DLL: crdb_b1.dll.
The connection is successful from another PC that only has the Client installed (and uses the License server on our server, which also contains the databases.)
I have a local installation with my own license server. I am not even able to connect to the database on my local PC.
Please can anyone explain why this isn't working?
Regards,
Rikard

Hi Rikard,
You may get better help if you post your question to the Business One forum. I can' t move your post.
Thank you

Cannot create new connection to SQL Server

When I try to create a connection from Oracle Sql Developer to SQL Server I get the following message:
Status: Failure -I/O Error: SSO Failed; Native SSPI Library not loaded. Check the java.library.path system property.

check if you installed JTDS driver. If not,
- go to http://sourceforge.net/project/showfiles.php?group_id=33291,
- extract the jar file,
- copy it to a convenient location (SQL Developer subfolder would be preferable)
- start sql developer and go to properties
- expand Database, go to Third Party JDBC drivers and add the .jar file above.
- recheck the connection.
Good luck,
Andrei

ADD a new connection to sql developer

Hi,
i downloaded the sql developer from the main site .i tried to adding a new connection.it showed the error no network adapter found .
first let me confirm one thing the database name and username,password are predefined ones are should i need to create those any before using these.
please let me know .i am struggling with this since a week.
Thanks in advance.
sreeram

Hi Sreeram,
The "no network adapter found" message seems more like a Windows setup/configuration issue. If you really meant some other error instead, perhaps like
The network adapter could not establish the connectionthen the following may shed some light:
Re: SQL developer download - unable to connect
So in fact you do need a database to access, either local or remote. The act of installing a database locally will create "predefined" usernames with passwords you can override.
Hope this helps,
Gary

New Connection in SQL Developer

Hi all,
Everything went well from the setting up of APEX, SQL DEV to the exporting of the Northwind DB. I am now trying to create a connection with the credentials in the application migration workshop pdf. I came across the following error : Listener does not currently know of SID given in connect descripter....
tried to use 10GR2 which was specified and XE, the one of my database...
can someone please help me in this regard, urgently.
Thanks in Advance
Melvin

Hi Melvin,
I'm not sure which connection you are trying to make. You mention that you are trying to make a connection using the credentials in the application migration workshop pdf - which credentials are you talking about? Please note that any username/password/host/SID information used in the documentation is for demonstration purposes. You should supply the information that corresponds with your environment. Is "10GR2" the SID for your Oracle Database instance? Please ensure that you use the connection details that correspond with your own database instance.
If you are attempting to create a connection in Oracle SQL Developer to the newly migration Oracle schema, then ensure that the username/password combination you supply corresponds with the user created at the top of the generated DDL statements by the Migration Workbench e.g. if your database is called Northwind, then you can expect the username/password combination to be northwind/northwind.
If you are attempting to create a connection to the Oracle database for your Migration Repository, please ensure that the user you are connecting as has the required privileges necessary for carrying out a migration. Please refer to the Migration documentation in Oracle SQL Developer for further information.
I hope this helps.
Regards,
Hilary

Able to connect from SQL-Assistant BUT unable to connect from Sql Developer

Hello,
I have been troubling with this issue for the last two weeks...tried so much, but could not able to resolve....
sqlplus username/password@IPAddress:port/ServiceName
I am able to connect to DATABASE from SQLAssistant only when I provide string like ABOVE........If I dont mention the SERVICE, m unable to connect to DB...
Now the biggest issue is with SQL Developer.....m not at all able to connect to DB using SQL Developer....I tried all options...but no use...
waiting for your reply......
Thanks Much in Advance.....

What have you tried, and what error messages are you getting?
When you create a connection in SQL Developer, you should specify IPAddress,port,ServiceName as in your sqlplus connect string.

SBO0001 error DBD:ORA12154 error while creating new connection

Dear All,
I have installed XIR3 on a windows 64 bit with oracle 10g R2 client.
The CMS is up and running and I am able to connect to the infoview and view the lsit of all the migrated objects from BOXIR2.
But, when I am trying to create a new connection for the universe or trying to execute the existing reports i am getting the following error.
(i.e I guess BO is unable to connect to DB)
*SBO0001 error DBD:ORA12154 error while creating new connection
I tried various solution from BOB but still could not solve this. Please anyone suggest few tips regarding this case
Business objects: CMS is running and able to connect to infoview and able to log on to CMC
Database client: Able to log on to DB using sqlplus and tnsping is working.
the details of the software are as follows
*BO Server configuration
OS: Windows Server 2008 R2 64 bit
Business Objects XI R3 3.0
Oracle client 10gR2 32 bit
*Database server configuration

Mike :
I am having a similar issue with the BOE and Oracle.
Can you please provide details of which Oracle client you ended-up using..?
32-bit or 64-bit...?
Oracle client version...?
Specific client patches applied..?
Thanks,

I have followed the steps to the last letter using: Data Loading and the Oracle Database Cloud Service
What I have done on the dashboard and APEX:
I changed the password of the SFTP user.
I have created a new user on APEX that belongs to the SQL Developer Group and changed the 'Require change on Password on First Use' to NO before creating the user
SQL Developer:
I set the database username to the new user I created in APEX
I set the database URL to the URL I used to reach the APEX page...https://databasetrial1875-******.db.us1.oraclecloudapps.com/apex/
I set the SFTP username to the username listed next to 'Service SFTP User Name' on the dashboard
I set the SFTP hostname to: sftp.us1.cloud.oracle.com
I left the port set to 22
When I login on SQL Developer to database, I use the password for the user I created in APEX
Thanks in advance to all who help!

Hi,
You have to use the admin account to add the admin role to the developer account. Can you please try this and let me know of your feedback.
The settings you added look good, and the you have the latest version of Sql DEVELOPER , ...so this should be an issue.
Maybe you have some firewall setting on your computer, that are blocking the connection?
If , after checking all of the above you still have an issue, please contact oracle support via the chat on the cloud.oracle.com and ask the engineer to open a Service Request under your name.
Thanks,
Flori
