Connection to Oracle 12c from a standalone java application succeeds when ojdbc6.jar or ojdbc5.jar is used.
Connection String : jdbc:oracle:thin:#serverName:port:sid
Whereas the same connection string fails when connecting through Websphere with the following exception.
java.sql.SQLException: ORA-28040: No matching authentication protocol
DSRA0010E: SQL State = 99999, Error Code = 28,040
Note : Tried ojdbc8.jar and ojdbc6.jar
The ORA-28040: No matching authentication protocol error generally indicates that you are using an older JDBC driver with a newer database. You should either update your JDBC driver so that it is the same version as the database or update your sqlnet.ora file with the appropriate SQLNET.ALLOWED_LOGON_VERSION_SERVER/SQLNET.ALLOWED_LOGON_VERSION_CLIENT values. See Oracle's SQLNET documentation for more information.
Note that if you think you are using the same version JDBC driver as the database it is possible that a different JDBC driver is being picked up in the WebSphere environment. If that is the case:
Check that there are no additional JDBC drivers packaged with your application.
Check if there are other Oracle JDBC Providers configured in WebSphere using an older JDBC driver. If so either modify your configuration so all of your providers are using the same version Oracle JDBC driver or you will need to Isolate your JDBC Providers.

Trying to achieve JDBC connection to reverse engineer from tables to hibernate using JBOSS tools, need JDBC connection for it, but the option for window->preference->Data Management-> Connectivity->Driver definitions shows only "Generic JDBC Driver" only for connection. Need SQL Server driver option.

I'm connecting to a Firebird 3.0 database using the Jaybird JDBC 3.0.3 driver. I'm connecting from within the ColdFusion Administrator -> Data Sources area. In the past, using JDBC 2.0 driver I created my data source as follows.
JDBC URL: jdbc:firebirdsql:localhost/3050:DATABASE_FILE_NAME
Driver Class: org.firebirdsql.jdbc.FBDriver
Username: USERNAME
Password: PASSWORD
However, this is not working now. I do not see anything obvious that I'm missing. I just get the error
Timed out trying to establish connection
I did read that Jaybird 3.0 does not support Wire Encryption - so I need to set it to Enabled (not Required which is the default). I have already done this in the firebird.conf file and restarted the Firebird service.
Turns out I needed to download and use the Jaybird driver for JDK 1.7 rather than 1.8. After I did that and restarted ColdFusion everything worked.
I have database username and password to access oracle db and also have service url like https://X-X.X.X.oraclecloudapps.com/apex/.
Can anybody know how to connect this db using JDBC connection.
I tried using oracle thin driver but somehow it failes.
Sample java code:
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:#//X.X.X.X.oraclecloudapps.com:1521/sid", "username", "****");
It throws
Exception in thread "main" java.sql.SQLRecoverableException: Io exception: The Network Adapter could not establish the connection
I don't know SID here, it would be helpful if anybody give steps to find SID/ServiceName from Oracle Cloud dashboard.
You can't use JDBC to connect to the Database Schema Service. You can connect using the API or tools that utilize the REST API. For data upload to Oracle Database Schema Service, use Oracle SQL Developer, the Oracle Application Express SQL Workshop Data Upload Utility or the Oracle Application Express Data Load utility. Read more here: http://docs.oracle.com/cloud/latest/dbcs_schema/CSDBU/GUID-3B14CF7A-637B-4019-AAA7-A6DC5FF3D2AE.htm#CSDBU177
There is only three way to connect Database Schema Service.
From an Oracle Application Express application running in Database Schema Service
From a Java application running in an Oracle Java Cloud Service
Through RESTful Web services
Try the following JDBC URL to resolve the issue
"jdbc:oracle:thin:#host-address:1521/sid";
Note / is used after port and Not :
When i use IBM data Studio to connect to our db2 v8 z/os database the JDBC connection url generated is this.
jdbc:db2://host:port/LOCATION:retrieveMessagesFromServerOnGetMessage=true;emulateParameterMetaDataForZCalls=1;
contains this parameter setting: emulateParameterMetaDataForZCalls=1
What does this setting do? Why do i need it?
This parameter enables the use of the method PreparedStatement.getParameterMetaData() against a DB2 for z/OS data source.
I tested this URL and with other formats:
jdbc:oracle:thin:NAME/NAME#//NAME.cbyuxlvomj.us-east-1.rds.amazonaws.com:1521/NAME
With this and others drivers:
http://download.oracle.com/otn/utilities_drivers/jdbc/112/ojdbc6dms.jar
Configuration with problem
WSO2 DataServices 2.7 and 3
Oracle-se1(11.2.0.2.v7)
Old configuration that is running
WSO2 DataServices 2.7
Oracle 10
The error that we receive is:
Error testing connection : Error during executing validation query : Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
Please someone can help-me?
Thanks!
