Hi ManKeer,

In case a subscription is configured to use an Item Group the string representing the group name can have a free format.
But the getItems method must always return the full list of...

Hi ManKeer,

No, it's up to your Metadata (notifyUser method) to detect the case.
In order to kill the old client session you have various options depending on the Lightstreamer version and...

Certainly, since you have added parameters in the `<data_provider>` section, you will need to add code to read and use them. Therefore, in the `init` method of your Data Adapter, you will need to...

Hi Vinayak Singh,

For such a simple example like HelloWorld, the configuration file of the AdapterSet is equally simple, and you can find it described here:...

It means that the Lightstreamer server receives an update from the Data Adapter for an item name that actually doesn't currently have an active subscription for.

Hi ManKeer,

If you are expecting only one client session, there are two strange things that can be inferred from this request list:

1) It seems that there are two streams of parallel requests...

Hi rthompson,

Please consider that the subscription_timeout_millis setting does not apply in case an explicit unsubscribe request has been received for that item.
It applies only in cases where...

Hi ManKeer,

If the delays involve only a subset of the clients and then we can exclude a general problem affecting the whole server you should look for the "NIO write queue" and "NIO write queue...

Hi Vinayak,

No sorry, unfortunately we have no specific documentation.
You should rely on the official exec plugin documentation: https://www.mojohaus.org/exec-maven-plugin/index.html
But you...

Hi Vinayak,

This is the project of a Remote Data Adapter the can be launched stand-alone via maven: https://github.com/Lightstreamer/Lightstreamer-example-StockList-adapter-java-remote

Hi andres1,

We plan to release an official C++ library in the near future, but honestly it's not expected in the very short term.
So at the moment you have to implement the TLCP protocol, at...

Hi Vinayak,

No, unfortunately at the moment there is no any example that launches contextually the server directly from maven.
As said in one of the previous posts, you should create a specific...

Hi Vinayak,

The "Hello World Tutorial - Java Adapter" project target is to create an In-process Data Adapter.
This type of adapters do not provide the possibility of being launched as stand alone...

Hi Vinayak,

With the pom file provided in the Helloworld Java project you can only build the jar of the demo: mvn package.

In order to deploy your jar and run the demo you have to follow the...

Hi Vinayak Singh,

A typical deployment scenario of an application that uses Lightstreamer for real-time data is the one shown here:
...

Hi Vinayak Singh,

Sorry, but I'm not sure I understand what exactly your needs are.

The minimal command to launch the Ligthstreamer server without use one of our scripts is:
1. Open a command...

Hi Vinayak Singh,

Detailed instructions for a quick setup of Lightstreamer server are contained in the file GETTING_STARTED.TXT that you can find in the Lightstreamer home directory.
Anyway, for...

Hi jvanhensberg,

Please refer to the inline comments of <https_server> parameter in the "lightstreamer_conf.xml" configuration file in order to properly configure your Lightstreamer server.
You...

Hi chickendev,

So your problem is that you have changed the Data Adapter code, such that it no longer provides the snapshot, but then you also no longer receive the normal real-time updates?...

Hi chickendev,

Yes, if for a client session there are no real-time updates to send and after a configurable timeout no updates have been sent, then a small keep-alive message is sent.
The timeout...

Hi chickendev,

First of all let me clarify that isSnaphot is a flag, which is used to identify an event as a snapshot and differentiate it from all others which are considered real-time events....

Hi Nghiep,

About the ClassLoader, the isolation level of Adapter Sets can be configured in the adapters.xml file. Please refer to the classloader parameter of the provided template of adapters.xml...

Hi Nghiep,

Yes, I can confirm that multiple Adapter Sets can be plugged onto a single Lightstreamer Server.
So your plan of migration makes totally sense.

Hi chickendev,

What is available in the Metadata interface is the selector mechanism, which allows you to have, for a particular set of Items, a call to a Metadata method for each update received...

Hi rthompson,

Yes I can confirm that the feature has not been ported to c# remote library yet.
In this case you should consider the workaround suggested in this post:...
