通过oracle直接连接到db2数据库时连接，但是通过java代码连接时抛出异常

Question

Hi I am getting below exception when i try to connect DB2 server thru java

com.ibm.db2.jcc.b.ao: [jcc][t4][2010][11246][3.53.70] Connection authorization failure occurred. Reason: Local security service non-retryable error. ERRORCODE=-4214, SQLSTATE=28000

When I tried connecting the DB2 using SQL Developer (With jars added in Third Party tool) the connection was successful. I included all the required db2jcc,db2jcc4 and db2jcc_license jar files in the project. But it throws exception.

try{
    Class.forName("com.ibm.db2.jcc.DB2Driver");
    String url = "jdbc:db2://myhost:portNumber/dbname";                
    Connection con = DriverManager.getConnection(url, "uname","password"); 
}catch(Exception e){
    e.printStackTrace();
}

3.53.70 driver version corresponds to quite an old 9.5.3 db2 version. You should try to download a jdbc driver corresponding to your db2 version. DB2 JDBC Driver Versions and Downloads
