Pentaho Kettle: list of remote Carte objects IDs from Java - pentaho

I already know how to run and attach a transformation running on a remote Carte server using Java given transformation's Carte Object ID:
KettleEnvironment.init();
TransMeta transMeta = new TransMeta("file.ktr");
Trans trans = new Trans(transMeta);
SlaveServer ss = new SlaveServer("test", IP, PORT, "cluster", "cluster");
TransExecutionConfiguration jec = new TransExecutionConfiguration();
jec.setRemoteServer(ss);
String carteObjectId = trans.sendToSlaveServer(transMeta, jec, null, null);
and
KettleEnvironment.init();
SlaveServer ss = new SlaveServer("test", IP, PORT, "cluster", "cluster");
SlaveServerTransStatus state = ss.getTransStatus(transMetaName, carteObjectId, 0);
List<StepStatus> list = state.getStepStatusList();
However, for a more general (and usable) remote monitoring I need to get the whole list of the Object IDs of the running/run transformations on the remote Carte server. Which methods can I use to get such a list ?

List<SlaveServerTransStatus> transStatus = slave1.getStatus().getTransStatusList();
for(SlaveServerTransStatus transStatu:transStatus){
System.out.println(transStatu.getTransName()+"--"+transStatu.getStatusDescription()+"---"+transStatu.getId());
}

what is correct use of consumer groups in spring cloud stream dataflow and rabbitmq?

A follow up to this:
one SCDF source, 2 processors but only 1 processes each item
The 2 processors (del-1 and del-2) in the picture are receiving the same data within milliseconds of each other. I'm trying to rig this so del-2 never receives the same thing as del-1 and vice versa. So obviously I've got something configured incorrectly but I'm not sure where.
My processor has the following application.properties
spring.application.name=${vcap.application.name:sample-processor}
info.app.name=#project.artifactId#
info.app.description=#project.description#
info.app.version=#project.version#
management.endpoints.web.exposure.include=health,info,bindings
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
spring.cloud.stream.bindings.input.group=input
Is "spring.cloud.stream.bindings.input.group" specified correctly?
Here's the processor code:
#Transformer(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT)
public Object transform(String inputStr) throws InterruptedException{
ApplicationLog log = new ApplicationLog(this, "timerMessageSource");
String message = " I AM [" + inputStr + "] AND I HAVE BEEN PROCESSED!!!!!!!";
log.info("SampleProcessor.transform() incoming inputStr="+inputStr);
return message;
}
Is the #Transformer annotation the proper way to link this bit of code with "spring.cloud.stream.bindings.input.group" from application.properties? Are there any other annotations necessary?
Here's my source:
private String format = "EEEEE dd MMMMM yyyy HH:mm:ss.SSSZ";
#Bean
#InboundChannelAdapter(value = Source.OUTPUT, poller = #Poller(fixedDelay = "1000", maxMessagesPerPoll = "1"))
public MessageSource<String> timerMessageSource() {
ApplicationLog log = new ApplicationLog(this, "timerMessageSource");
String message = new SimpleDateFormat(format).format(new Date());
log.info("SampleSource.timeMessageSource() message=["+message+"]");
return () -> new GenericMessage<>(new SimpleDateFormat(format).format(new Date()));
}
I'm confused about the "value = Source.OUTPUT". Does this mean my processor needs to be named differently?
Is the inclusion of #Poller causing me a problem somehow?
This is how I define the 2 processor streams (del-1 and del-2) in SCDF shell:
stream create del-1 --definition ":split > processor-that-does-everything-sleeps5 --spring.cloud.stream.bindings.applicationMetrics.destination=metrics > :merge"
stream create del-2 --definition ":split > processor-that-does-everything-sleeps5 --spring.cloud.stream.bindings.applicationMetrics.destination=metrics > :merge"
Do I need to do anything differently there?
All of this is running in Docker/K8s.
RabbitMQ is given by bitnami/rabbitmq:3.7.2-r1 and is configured with the following props:
RABBITMQ_USERNAME: user
RABBITMQ_PASSWORD <redacted>:
RABBITMQ_ERL_COOKIE <redacted>:
RABBITMQ_NODE_PORT_NUMBER: 5672
RABBITMQ_NODE_TYPE: stats
RABBITMQ_NODE_NAME: rabbit#localhost
RABBITMQ_CLUSTER_NODE_NAME:
RABBITMQ_DEFAULT_VHOST: /
RABBITMQ_MANAGER_PORT_NUMBER: 15672
RABBITMQ_DISK_FREE_LIMIT: "6GiB"
Are any other environment variables necessary?

remote process with wmi, get return value

the following code connects to a remote pc and execute the process try.exe located on that pc.
string prcToRun = "\"C:\\try.exe\" \"";;
object[] theProcessToRun = { prcToRun };
ConnectionOptions theConnection = new ConnectionOptions();
theConnection.Username = "domain\\user";
theConnection.Password = "password.";
ManagementScope theScope = new ManagementScope("\\\\192.168.1.1\\root\\cimv2", theConnection);
ManagementClass theClass = new ManagementClass(theScope, new ManagementPath("Win32_Process"), new ObjectGetOptions());
theScope.Connect();
theClass.InvokeMethod("Create", theProcessToRun);
It works fine, because "try.exe" does what I expect. However I'd like to obtain back the result of try.exe execution. Is it possibile with wmi? At least I need to know when try.exe ends, but it would be better return a value. I know it would be possibile with psexec, but I can't use it.
Thank you

How to add extra data to a member in MDS?

I'm running MDS on a virtual machine and trying to access the service from my host OS.
I've been able to add something to the database but my data is all over the place and in the Master Data Manager (website) I don't see the new member.
I suppose I shouldn't be using Attributes but something else but what and how? Are there tutorials because I can't find any ...?
Here's the code I'm using:
International international = new International();
EntityMembers entityMembers = new EntityMembers();
// Set the modelId, versionId, and entityId.
entityMembers.ModelId = new Identifier { Name = modelName };
entityMembers.VersionId = new Identifier { Name = versionName };
entityMembers.EntityId = new Identifier { Name = entityName };
entityMembers.MemberType = memberType;
Collection<Member> members = new Collection<Member>();
Member aNewMember = new Member();
aNewMember.MemberId = new MemberIdentifier() { Name = employee.FullName, Code = aNewCode, MemberType = memberType };
Collection<MDS.Attribute> attributes = new Collection<MDS.Attribute>();
MDS.Attribute attrOrgUnit = new MDS.Attribute();
attrOrgUnit.Identifier = new Identifier() { Name = "OrganizationalUnit" };
attrOrgUnit.Value = employee.OrganizationalUnit;
attrOrgUnit.Type = AttributeValueType.String;
attributes.Add(attrOrgUnit);
aNewMember.Attributes = attributes.ToArray();
members.Add(aNewMember);
entityMembers.Members = members.ToArray();
// Create a new entity member
OperationResult operationResult = new OperationResult();
clientProxy.EntityMembersCreate(international, entityMembers, false, out operationResult);
HandleOperationErrors(operationResult);
I have been able to fix my own problem.
First of all: creating separate variables with collections and converting them to arrays afterwards is not necessary. The code from the tutorials works but fails to mention that, when adding the service reference, you have to configure it (right-click on the service reference -> configure) to use Collections as "Collection type" instead of arrays and to generate message contracts.
Second, the code above with the attributes is correct and works perfectly. The problem I had which failed to add messages with attributes was unrelated. It was a connection/authentication problem between my Host OS and Guest OS.
Hope this helps someone.

Mobile Emulator Connection Failure (Merge Replication)

I am attempting to replicate a SQL CE 3.5 SP1 database but upon syncrhonization, I am thrown the following error:
"Failure to connect to SQL Server with provided connection information. SQL Server does not exist, access is denied because the IIS user is not a valid user on the computer running SQL Server, or the password is incorrect."
I am using the Windows Mobile 6 Professional emulator and the machine I am attempting to connect to is a Windows Virtual Machine running Windows XP Professional SP3. I have configured the network adapter settings for the emulator (I can access web pages), verified user permissions, double checked IIS settings, and triple checked my connection string:
SqlCeReplication rpl = null;
try
{
// Creates the replication object.
rpl = new SqlCeReplication();
// Establishes the connection string.
rpl.SubscriberConnectionString = #"Data Source = \Program Files\ParkSurvey\ParkSurvey.sdf; Password = *; Temp File Max Size = 512;
Max Database Size = 512; Max Buffer Size = 512; Flush Interval = 20; Autoshrink Threshold = 10; Default Lock Escalation = 100";
// Sets the Publisher properties.
rpl.PublisherSecurityMode = SecurityType.NTAuthentication;
rpl.Publisher = "PUBLISHER";
rpl.PublisherLogin = "INDICOPUBLIC\\subuser";
rpl.PublisherPassword = "*";
rpl.PublisherDatabase = "PUBLISHER";
rpl.Publication = "ParkSurveyPublication";
// Sets the internet replication properties.
rpl.InternetUrl = "http://replication/sqlce/sqlcesa35.dll";
rpl.InternetLogin = "INDICOPUBLIC\\subuser";
rpl.InternetPassword = "*";
rpl.ConnectionManager = true;
// Sets the Distributor properties.
rpl.Distributor = "PUBLISHER";
rpl.DistributorLogin = "INDICOPUBLIC\\subuser";
rpl.DistributorPassword = "psrAdmin";
rpl.DistributorSecurityMode = SecurityType.NTAuthentication;
// Sets the timeout properties.
rpl.ConnectionRetryTimeout = 120;
rpl.ConnectTimeout = 6000;
rpl.ReceiveTimeout = 6000;
rpl.SendTimeout = 6000;
// Sets the Subscriber properties.
rpl.Subscriber = "ParkSurveySubscriber";
rpl.HostName = "Mobile1";
rpl.CompressionLevel = 6;
rpl.ExchangeType = ExchangeType.BiDirectional;
// Call the replication methods.
rpl.Synchronize();
}
catch (SqlCeException sqlEx)
{
MessageBox.Show(sqlEx.Message);
}
finally
{
// Disposing the replication object
if (rpl != null)
{
rpl.Dispose();
}
}
I have also attempted to open the host machine itself in File Explorer on the mobile emulator and am prompted that "The network path was not found.". This leads me to believe it is ActiveSync issue within the emulator itself. Does anyone have any advice?
Try with IP adresse instead of hostname, and test the agent URL from IE on the device. Make sure to use the latest build of 3.5 SP2 on all components if your DB server is SQL 2012

access Mbeans on weblogic

From the documentation of oracle :
Domain Runtime MBean Server : This MBean server also acts as a single
point of access for MBeans that reside on Managed Servers.
what i want to do is to use this fact to access all my custom mBeans scattered in several managed servers.
for example assume that i have two nodes server-1 server-2 .
how can i access all of the custom mBeans on both server-1 server-2 by connecting to the administrator node ?
i dont want to remotly access each node to return the result i want a single entry point
i managed to get the names of the servers and the states and other information by doing this
JMXConnector connector;
ObjectName service;
MBeanServerConnection connection;
String protocol = "t3";
Integer portInteger = Integer.valueOf(<admin server port>);
int port = portInteger.intValue();
String jndiroot = "/jndi/";
String mserver = "weblogic.management.mbeanservers.runtime";
JMXServiceURL serviceURL = new JMXServiceURL(protocol, "<serverName>", port,
jndiroot + mserver);
Hashtable h = new Hashtable();
h.put(Context.SECURITY_PRINCIPAL, "weblogic");
h.put(Context.SECURITY_CREDENTIALS, "weblogicpass");
h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES,
"weblogic.management.remote");
h.put("jmx.remote.x.request.waiting.timeout", new Long(10000));
connector = JMXConnectorFactory.connect(serviceURL, h);
connection = connector.getMBeanServerConnection(); service = new ObjectName("com.bea:Name=DomainRuntimeService,Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean");
ObjectName[] ons = (ObjectName[]) connection.getAttribute(service, "ServerRuntimes");
int length = (int) ons.length;
for (int i = 0; i < length; i++) {
String name = (String) connection.getAttribute(ons[i],
"Name");
String state = (String) connection.getAttribute(ons[i],
"State");
String internalPort = (String) connection.getAttribute(ons[i],"ListenPort");
System.out.println("Server name: " + name + ". Server state: "
+ state);
but i need to access the custom Mbeans created on each server and not only the information
maybe my question wasnt clear but i found an answer and i will share it here now :
Question summary : i need to access custom mBeans exists in a managed server by connecting to the administration server from a client application.
Answer :
to do that you need to deploy your application to the administrator server (i tried remote but it didn't work )
you need to connect to the DomainRuntimeServiceMBean because it provide a common access point for navigating to all runtime and configuration MBeans in the domain .
when searching for the Object name add Location=
here is the code:
Hashtable props = new Hashtable();
props.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
props.put(Context.SECURITY_PRINCIPAL, "<userName>");
props.put(Context.SECURITY_CREDENTIALS, "<password>");
Context ctx = new InitialContext(props);
MBeanServer server = (MBeanServer)ctx.lookup("java:comp/env/jmx/domainRuntime");
ObjectName on =new ObjectName("com.<companyName>:Name=<Name>,Type=<Type>,Location=<managed_server_name>");
boolean boolresult=(Boolean)server.invoke(on, "<method_Name>",
new Object[]{"<ARG1>","<ARG2>","<ARG3>"}
,new String[]{"java.lang.String","java.lang.String","java.lang.String"});
out.print(boolresult);
