I'm trying to test a connection to Remedy using the Java API, i.e. arapi7604_build002.jar.
According to the documentation, 4100 is a common AR System server port: https://docs.bmc.com/docs/display/public/itsm81/Port+information, but this isn't working for me:
private ARServerUser server;
private RemedyJavaAPITest() {
server = new ARServerUser();
server.setServer("fqd.com");
server.setUser("userName");
server.setPassword("pass123");
server.setPort(???);
}
public static void main(String[] args) {
RemedyJavaAPITest test = new RemedyJavaAPITest();
test.connect();
test.cleanup();
}
Error:
Connecting to AR Server...
ERROR (90): Cannot establish a network connection to the AR System server; Connection timed out: connect fqdn.com:4100

Usually the port in which AR Server is listening for incoming connections can be configured. Please get it confirmed with your Remedy Administrators/Developers Below are some of the points you should take care while doing this.
Make sure that the machine where AR server is installed is reachable from the machine where you are running your java program.
setServer() required hostname(anything) which will connect to your target machine(hostname should be a resolvable one)
If you are able to connect to host machine and port number is wrong, you would getting an error message which says 'Connection Refused'. But you are getting 'timed out', which usually means your connection request is not received any reply from the network. So confirm your host name.
3700 is also commonly used for AR Servers.

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:
java.sql.SQLException: [Cloudera][ImpalaJDBCDriver](500164) Error initialized or created transport for authentication: [Cloudera][ImpalaJDBCDriver](500169) Unable to connect to server: GSS initiate failed.

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'm using two H2 databases in my Java projects. Recently, I changed my computer and since then I have no problem with connecting to one of those databases using my Java code but problems with the other one. It's exactly the same code (up to PATH_TO_DATABASE) I use to start the connection:
import java.sql.DriverManager;
import java.sql.SQLException;
public class DatabaseConfig {
private static java.sql.Connection connection;
public static void init() {
if (connection == null) {
try {
connection = DriverManager.getConnection("jdbc:h2:tcp://192.168.178.50:9092/C:/Users/PATH_TO_DATABASE", "USER", "PW");
} catch (SQLException e) {
System.err.println("SQLException");
e.printStackTrace();
System.exit(0);
}
}
}
[...]
}
This is the stack trace I get:

Using the web interface I can connect to both databases easily.
I'm a little bit lost here since I can't figure out what's going wrong with one of the databases. The strange thing is that everything works fine with the other database.
EDIT: I just realized that the IP address in the error message is different from the one in the code (192.168.178.21:9092 vs. 192.168.178.50:9092). Maybe this is th ereason of the error. The one in the code is the correct IP address. Why do I get a different one in the error message? Is that the reason of my problem?
If it's a remote connection, do an ipconfig to find out if the 192.168.x.x. address is changed.
If it's a local connection, you can simplify your URL as
jdbc:h2:~/PATH_TO_DATABASE
I just solved the problem (it was kind of my stupidity): The project couldn't build on the new computer because the H2 jar was not properly included in the build path. That's why eclipse called all the time the old .class file and hence tried to connect to the old computer (192.168.178.21:9092) instead to the new one (192.168.178.50:9092). I didn't realize that eclipse didn't compile and was executing old stuff.
I have rabbitMQ server running on vm.
I am following rabbitMQ java tutorial.
It works fine locally on the vm but when trying to send from the host I get an exception

public class Send {
private final static String QUEUE_NAME = "hello";

}
}
I can ping the server at 192.168.198.100 but I can't access the managment UI at
192.168.198.100:15672/
So could anyone help me figure out what's wrong with this issue?
Thanks in advance.
1.
You are using guest guest as credentials, and it is not allowed for remote IP.
Please read this: Can't access RabbitMQ web management interface after fresh install
then you have to add this:
factory.setPassword("test");
factory.setUsername("test");
2.
Did you enable the management UI? if not use:
rabbitmq-plugins enable rabbitmq_management
3.
check your firewall configuration maybe the ports 5672 and 15672 are closed.
You can use telnet to test the ports:
telnet 192.168.198.100 5672
Trying 192.168.198.100...
Connected to 192.168.198.100.
Escape character is '^]'.
and:
telnet 192.168.198.100 15672
Trying 192.168.198.100...
Connected to 192.168.198.100.
Escape character is '^]'.
I am running the following method:
private static void bulkLoad() throws SQLException{
final Connection connection = DriverManager.getConnection(connectionURL);
final Statement s = connection.createStatement();
s.execute("LOAD DATA LOCAL INFILE 'LoadData.txt' INTO TABLE emails FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'");
}
But am inconsistently (sometimes I get it and sometimes I don't) getting this error:

At first, I figured it may be a timeout issue, but I checked my wait_timeout and saw it is set to 28800, which should be more than enough time. Does anyone know what's wrong?
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.
