I am getting
no ocijdbc11 in java.library.path
when trying to connect to the oracle database and I am not sure why and how to correct the issue . I am using: Oracle SQL Developer and Oracle Client 11G. I need help on correcting this issue. I have edited the sqlnet.ora file to add the below details:
NAMES.DIRECTORY_PATH= (LDAP,TNSNAMES,EZCONNECT)
SQLNET.EXPIRE_TIME=2
SQLNET.INBOUND_CONNECT_TIMEOUT=45
However, I am still getting the error message. Apparently there is an LDAP.ORA file as well, but I don't know where it is and how to edit that file. It looks like I need to add below information
DEFAULT_ADMIN_CONTEXT="###########"
DIRECTORY_SERVERS = (###########)
DIRECTORY_SERVER_TYPE = OID
Also, my TNSNames.ora file is blank, I am not sure why it is blank. Maybe I need to install Oracle Client 11g or 12c again. Thanks
I figured this out. I was connecting the wrong database instance. There are two similar databases: ###10### AND ###01###1. I needed to connect to ###10### not ###01###1 for the data that I need. The database instances are very similar and I connected to the wrong one.

I've got a JDBC-URL like such to connect to an Oracle 12c database:
jdbc:oracle:thin:#ldap://oraldap:389/thisdb,cn=OracleContext,dc=world
As can be seen, connection happens through LDAP.
Now I want to connect to same database via "Oracle Provider for OLE DB". Question is, what should I enter as data source here? Tried "ldap://oraldap:389/thisdb,cn=OracleContext,dc=world" - but this naturally didn't work. As far as I understand, I could enter a TNS-string like (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)))- but I didn't gather how to represent the ldap-part.
What's the way to do this?
Ok, solved - I needed to have the tns-configuration files from Oracle. So namely it is the files ldap.ora, sqlnet.ora and tnsnames.ora which I put into a specific folder plus creating the environment variable TNS_ADMIN. For connecting through OLE_DB I enter the database name as data source - and it works!
I am getting the ORA-12560: TNS:protocol adapter error when I try to log onto Oracle. Everyplace I have looked to fix this issue says I need to change something in Services.msc, but when I go there, I'm not finding any of the oracle services that I'm supposed to be changing.
I have found absolutely no fix for this issue and after several hours, I'm hoping you guys can maybe see what I'm doing wrong.
SQL Developer is just a query tool. The Oracle database is a separate product that you need to install
So I got connected to Oracle 11g in cmd as follows
However, when I type the same username and password in Oracle SQL Developer, it does not work. And I have uname and pwd, what goes in the connection name?
This what I got, when i entered a connection name and My uname and PWD
Oracle SQL Developer
Just give any string in your connection name, that is used for identify different connection in sql developer.
Like,
Connection name : Connection_1
username : system
password : yourpass
If you want to create another connection to another database or another schema then you have to give another name and by login you can directly access that particular schema.
Hope it will help.
I think the issue might be that SQL Developer uses a different tnsnames.ora file. The file can be set under:
Tools>Preferences>Database>Advanced
Choose the correct tnsnames directory there.
Depending on your developer version, you might also want to set the Oracle Client folder.
After that in your connection dialog choose TNS instead of BASIC. And pick the tnsalias name from the list from the file.
Let me know if that works.
I also faced the same issue and after trying series of steps came to this conclusion.
1)Make sure to follow the blog to install the DB and check the validation steps too :
https://www.oracle.com/webfolder/technetwork/tutorials/obe/db/12c/r1/Windows_DB_Install_OBE/Installing_Oracle_Db12c_Windows.html
This blog makes sure that you are able to connect to SQL via CMD.
2) If you still face issue while connecting to SQL developer for the same configuration,check : Advanced system settings-->Environment variables-->system variables--> PATH
Make sure you have entry for the DB here.
Environment variable for DB
3) If above step is a success,check the tnsnames.ora and listener.ora files present in the location : dbhome_1\network\admin
These files should have a valid entry for the localhost and SID/service name.
Thanks,

I am new to Oracle database in general, but I'm attempting to get Oracle's SQL Developer running on a workstation that has pre-configured System DSNs created for an OracleRDB database. I've confirmed the ODBC connections are working because I can use MS Access to connect and link to the tables. The "test" options within ODBC also succeed. Now I am trying to get a similar connection created using SQL Developer so I can see the column types and write queries in a more useful editor.
Here's what I have available when examining the ODBC connection properties:
Now I'm trying to create a duplicate connection in SQL Developer, but I'm at a loss for why things don't work. I first tried using the default SQL Developer installation, but couldn't get things working. Then I discovered there's an OracleRDB extension available, so I installed that, but I keep getting this error when attempting to use similar values:
As I stated, these ODBC connections were pre-configured on the workstation I'm using, so I don't know anything more than what is provided by the Oracle ODBC driver window.
Is there something obvious I'm not seeing or doing to replicate this connection in SQL Developer? Or perhaps something else I can do to debug this to learn more?
UPDATE
On the advice of one answer I'm trying to make the connection with JDBC, but having a hard time understanding what I'm doing wrong. Here's another screenshot with the connection parameters I have available, but with the server and database names changed:
With these values (the port came from my tnsnames.ora file), if I try to make a JDBC connection I keep getting the following error from SQL Developer:
One final attempt I did was to use the proper values in the Oracle RDB tab, and when I use them and click 'test' the Testing Connection dialog just spins and never seems to return:
So I apologize for the long post here, but I'm struggling because there's just something I am really not understanding about how this all works. I appreciate everyone who took the time to read this question.
Oracle SQL Developer is a Java Application. You'll need to get the JDBC Driver for RDB.
Once you have that, in the SQL Developer preferences, find the Third Party JDBC section, and then use that to add an entry and point to the JAR for what you just installed.
Step by step instructions here.
Working connection string for RDB Thin Driver:
RDB_DB_CONN_STR = "jdbc:rdbThin://node.myplace.com:1707/";
where node.myplace.com is the name of the OpenVMS node hosting the RDB Thin Driver, 1707 is the port number assigned to the RDB Thin Driver.
I am trying to connect my grails project to Oracle databse(Oracle 12c) in windows(8) system. However, whenever I run my application I get following exception :
Caused by: org.apache.commons.dbcp.SQLNestedException:
Cannot create PoolableConnectionFactory (ORA-28040:
No matching authentication protocol)
Caused by:
java.sql.SQLException: ORA-28040:
No matching authentication protocol
According to internet suggestion I also tried editing my *.ora file but it is not working.
I added following snippet in sqlnet.ora file :
SQLNET.ALLOWED_LOGON_VERSION=10
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=10
SQLNET.ALLOWED_LOGON_VERSION_SERVER=10
Here i tried assigning (10,11,12) but neither of them is working.
Can anyone please help me with this ?
I deleted the ojdbc14.jar file and used ojdbc6.jar instead and it worked for me
Here is some text I found at experts-exchange:
Bug 14575666
In 12.1, the default value for the SQLNET.ALLOWED_LOGON_VERSION
parameter has been updated to 11. This means that database clients
using pre-11g JDBC thin drivers cannot authenticate to 12.1 database
servers unless theSQLNET.ALLOWED_LOGON_VERSION parameter is set to the
old default of 8.
This will cause a 10.2.0.5 Oracle RAC database creation using DBCA to
fail with the ORA-28040: No matching authentication protocol error in
12.1 Oracle ASM and Oracle Grid Infrastructure environments.
Workaround: Set SQLNET.ALLOWED_LOGON_VERSION=8 in the
oracle/network/admin/sqlnet.ora file.
This except for adding the following to sqlnet.ora
SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8
If you get "ORA-01017: invalid username/password; logon denied" error, then you need to re-create your password.
I resolved this issue by using ojdbc8.jar.
Oracle 12c is compatible with ojdbc8.jar
I was using eclipse and after trying all the other answers it didn't work for me.
In the end, what worked for me was moving the ojdb7.jar to top in the Build Path. This occurs when multiple jars have conflicting same classes.
Select project in Project Explorer
Right click on Project -> Build Path -> Configure Build Path
Go to Order and Export tab and select ojdbc.jar
Click button TOP to move it to top
Very old question but providing some additional information which may help someone else. I also encountered same error and I was using ojdbc14.jar with 12.1.0.2 Oracle Database. On Oracle official web page this information is listed that which version supports which database drivers. Here is the link and it appears that with Oracle 12c and Java 7 or 8 the correct version is ojdbc7.jar.
In the ojdbc6.jar is for 11.2.0.4.
Except for adding the following to sqlnet.ora
SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8
I also added the following to both the Client and Server, which resolved my issue
SQLNET.AUTHENTICATION_SERVICES = (NONE)
Also see post
ORA-28040: No matching authentication protocol
Adding
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8
is the perfect solution
sql.ora directory
..\product\12.1.0\dbhome_1\NETWORK\ADMIN
My Initial error is : ORA-28040: No matching authentication protocol exception
My DB version is 12.2 (Solaris) and client version is 11.2 ( windows). I have added below in both server and client sqlnet.ora
SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8
while connecting, I have got invalid username and password hence I have recreated the password ( same password ) in database which is resolved my issue.
While for most cases replacing ojdbc driver jar will be the solution, my case was different.
If you are certain you are using correct ojdbc driver. Double check if you are actually connecting to the database you are thinking you are. In my case jdbc configuration (in Tomcat/conf) was pointing to different database that had different Oracle version.
just install ojdbc-full, That contains the 12.1.0.1 release.
