I start the Gemfire server and bind him to the following address: myserver:10344. (Server and locator are started without problems) After that I check connection by the GFSH and client "pulse". All checks are successful. At the next step I develop my Java client and can't make a connection to the server.
My project is built by Maven with the following dependencies:
<dependency>
<groupId>com.pivotal.gemfirexd</groupId>
<artifactId>gemfirexd</artifactId>
<version>1.4.1</version>
</dependency>
<dependency>
<groupId>com.pivotal.gemfirexd</groupId>
<artifactId>gemfirexd-client</artifactId>
<version>1.4.1</version>
</dependency>
(All Gemfire dependencies are downloaded from http://dist.gemstone.com/maven/release)
Code source:
package com.mycompany.app;
import java.sql.Connection;
import java.sql.DriverManager;
public class App {
private void connect() {
try {
Class.forName("com.pivotal.gemfirexd.jdbc.ClientDriver");
String x = "jdbc:gemfirexd://myserver:10344/";
System.out.println(x);
final Connection conn = DriverManager.getConnection(x);
System.out.println("Connected ");
conn.close();
System.out.println("Disconnected");
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main( String[] args ) {
new App().connect();
}
}
I get the following exception:

I see that this is an old post but just in case you still want to know ....
The port you're specifying in your jdbc url is referring to the peer-membership discovery port, not the client-port (default 1527).
When you started the locator, there should've been info on the client port number as such (if you don't specify, default is 1527)
...
Starting GemFireXD Locator using peer discovery on: localhost[10334]
Starting network server for GemFireXD Locator at address localhost/127.0.0.1[1527]
Your jdbc url should be as follows:
String x = "jdbc:gemfirexd://myserver:1527/";

When trying to launch a Java Action within Oozie (CDH6.3.1) I get a GSS initiate failed. The code in question is pretty straight forward:
String impalaUrl = "jdbc:impala://pxyserver.global.ad:21050/default;SSL=1;AuthMech=1;KrbRealm=GLOBAL.AD;KrbHostFQDN=pxyserver.global.ad;KrbServiceName=Impala;sslTrustStore=/opt/cloudera/security/jks/truststore.jks;trustStorePassword=password";
Properties impalaProperties = new Properties();
impalaProperties.put("user", "svcaccount");
impalaProperties.put("password", "svcpassword");
impalaProperties.put("Driver", "com.cloudera.impala.jdbc41.Driver");
try {
setConnection(DriverManager.getConnection(impalaUrl , impalaProperties));
} catch (SQLException e) {
e.printStackTrace();
}
Running this gives the following stack trace:

I can fix this by kiniting with a keytab. However in our production environment Oozie runs this on one of many worker nodes and they do not have valid kerberos tickets. What are my options here? If possible I'd rather not kinit every day on each of our 40 worker nodes, is there a parameter I am missing here?
Thanks
I am face with a problem this day. I have tried to make a shakeout with my database, which is Oracle 11g installed localy on my pc and using JAR Ojdbc6, to connect on it using few line of java code. But anything what I have tried wasn't worked.
Tried :
- Connection with SQL DEV =>is worked
- Start Listener => All ready started
- Try to change the Ip from the URL => still can't connect
I see that is a generic error, but no one has a good response. I can't understand why with SQL DEV is working but with Eclipse not.
I Hope that someone can' help me,
This is my code :
package testare;
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
public class oracle {
public static void main(String[] argv) {
System.out.println("-------- Oracle JDBC Connection Testing ------");
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
} catch (ClassNotFoundException e) {
System.out.println("Where is your Oracle JDBC Driver?");
e.printStackTrace();
return;
}
System.out.println("Oracle JDBC Driver Registered!");
Connection connection = null;
try {
connection = DriverManager.getConnection(
"jdbc:oracle:thin:#localhost:1521/orcl", "hr","hr");
} catch (SQLException e) {
System.out.println("Connection Failed! Check output console");
e.printStackTrace();
return;
}
if (connection != null) {
System.out.println("You made it, take control your database now!");
} else {
System.out.println("Failed to make connection!");
}
}

Hope Someone helps me to find out the solution. Thanks
Actually the port 50000 is not opened that is the reason I got the error after change that port to 51020 it works fine also it connects with database.
String url="jdbc:db2://localhost:51020/TestDb";
Thanks
Cause
A possible cause for this problem is that TCP/IP is not properly enabled on your DB2 database server.
Resolving the problem
Use the db2set DB2COMM command from the DB2 command window to start the TCP/IP connection:
db2set DB2COMM=protocol_names
For example, to set the database manager to start connection managers for the TCP/IP communication protocols, enter the following commands:
db2set DB2COMM=tcpip
db2stop
db2start

I am new to the concept of OLAP DB.
Please excuse me if I missed out something in the Connection String.
I am trying to connect to connect to Microsoft Analysis Server(which is in different Domain) from my System.
While Connecting I am getting below Error.
Can you please let me know, what am I doing wrong?
I have executed the Steps Mentioned in :
https://msdn.microsoft.com/en-us/library/gg492140.aspx
and referred to the below link for connection to the Cube:
http://www.matthewgodding.com/articles/2010/2/27/getting-data-from-sql-analysis-services-using-java-and-olap4.html
After connecting to the CUbe, I need to execute MDX Query.
Please find the snippet of the code I am using:
public static void main(String[] args) {
try {
Class.forName("org.olap4j.driver.xmla.XmlaOlap4jDriver");
final Connection connection = DriverManager
.getConnection("jdbc:xmla:Server=http://Remote_Server_IPAddress/OLAP/msmdpump.dll;"
+ "Catalog=MyCatalog;"
+ "User='Domian\\Username';" \\ This is the Username to login to the Server
+ "Password='Password';" \\ This is the Password to login to the Server
+ "Cube=Cube;"); \\This is the Cube Name
I get the below Exception when I execute the program:

It's difficult to know what went wrong for you. Few things you could do,
Don't specify cube in connection. This is not listed as property in XMLA driver.
You can install fiddler and see what's going on with the requests.
Not sure if single quotes are needed in user name and password.
An application (e.g app.EAR) is deployed to a JBoss in my own machine and works fine. When I deploy it to a remote JBoss it is deployed, but when I try to access a functionality that needs a JNDI lookup to a remote EJB I get NameNotFoundException. So, it seems that it was unable to find the requested service. How come? If it works locally?
The dependency with the remote EJB interface is in the lib folder inside the EAR and of course is annotated with #Remote. The JBoss is exactly the same as the production one (I copied the whole JBoss from production to my machine to check if there is any configuration missing).
My lookup code is like this:
private Object lookup(String resourceName, String loginData) {
if (isPropagateUserCredentials() && (loginData == null || loginData.trim().equals(""))) {
throw new MyInfraConfigException("somemessage");
}
Properties envProperties = new Properties();
envProperties.putAll(this.jndiProperties);
if (loginData != null && !loginData.equals("")) {
envProperties.put(Context.SECURITY_PRINCIPAL, loginData);
envProperties.remove(Context.SECURITY_CREDENTIALS);
}
Context context = null;
try {
context = new InitialContext(envProperties);
return context.lookup(resourceName);
} catch (NameNotFoundException e){
String message = "Resource "+resourceName+" not found.";
LoggerFactory.getInstance(this.getClass().getName()).error(message, e);
throw new com.mypackage.NameNotFoundException(message, e);
} catch (NamingException e) {
String message = "Failed to find resource with JNDI: "+e.getMessage();
LoggerFactory.getInstance(this.getClass().getName()).error(message, e);
throw new com.mypackage.NamingException(message, e);
} finally{
if(context!=null){
try {
context.close();
} catch (NamingException e) {
e.printStackTrace();
}
}
}
}
The resourceName is ExternalResource.
The stacktrace is below:
29/06/2015 10:30:43 oracle.j2ee.clustering.ClusteringMessages warningInOpmnGetServers

Made an external simple java application in order to try to connect to the server and understand the cause of the problem. In fact, the problem is that I am getting a connection timeout:

This might be a network communication issue. I would check if the server does allow for communication on the remoting ports. Try telnet the server, if its configured to accept these requests:
telnet <server> <port>
If using default ports, I think this should be 4447. If this connection fails then answer the following:
1. Is there no firewall that might be blocking this communication.
2. Are you using the correct port as configured by your production server.
There could really be other reasons for the fail, but that would be a starting point.
