 Hi CEP team,

 I'm going through [1] to understand the CEP HA deployment. Have a few
 doubts to get clarified:


1. In a two node HA cluster, in the eventSync/hostName
configuration (event-processor.xml), do we need to provide the own host 
 IP?
If so, how does each nodes discover each other for event synchronization
purpose? For what exact purpose this eventSync configuration is used?
2. If we add a presenter node in addition to the two worker nodes,
I assume we should point to the presenter node from the both worker 
 nodes.
As per the configuration, seems this is a TCP level connection. Why do 
 we
need a TCP connection to the presenter?

What if we query the Mesos DNS in addition to port checking to see if its
updated? AFAIR what we are seeing is an java.net.UnknownHostException,
related to the DB hostname.

Re: [Dev] How do I create a cache instance that's local to the JVM?

Hi Nuwan,

You can use the CachingConstants.LOCAL_CACHE_PREFIX constant value as
defined in [1], You need to use two under score values.

Re: [Dev] [DAS 310] Changing the logo of the dashboard

[Prabushi Samarakoon]

Hi Sachith,

Currently, we don't allow to change the dashboard logo. But, you can easily
change the dashboard title which locates under the logo, using a custom
theme. You can add the url to the dashboard title if it is ok with your use
case. Otherwise you have to change in the dashboard.jag to change the logo.

Thanks,
Prabushi

[Jerad Rutnam]

Hi Sachith,

As of now only way you can do this is, extending "dashboard.jag" in portal
app.
You will have to change in 2 places. One is in the top bar and one is in
the side panel.

Hi all,

Regarding the current status of the project, I am working on the
development of the report Archive module, where the user can view the
previously sent error reports and also the current status of those issues.
Meanwhile I thought to look into the testing part of the project as well.
Is their any special testing framework used in Developer Studio testing,
that I need to adopt? I though to use JUnit. Is it OK?

[Dev] Issue with encrypting Userstore password with Secure Vault

[Maduranga Siriwardena]

Hi,

To encrypt a password in user-mgt.xml with cipher tool and then decrypt, it
should have the bellow formats according to [1].
"UserManager.Configuration.Property." + propertyName
"UserStoreManager.Property." + propertyName

This is not mentioned in the documentation [2] and it is hard to track the
issue with the logs (because it says only the credentials are invalid).
Userstore connection password does not comes in cipher-tool.properties by
default. And this makes it even harder to figure out the issue.

I have created a jira ticket to track this issue [3].

I'm not sure why these values are had coded. But I think it doesn't have to
be hard coded. We can simply find the property value in the xml element
with the namespace and the property name. If there is a particular reason
to do it in this way, at least update it in the documentation.

Re: [Dev] Clarifications on CEP HA Mode Deployments

[Vanjikumaran Sivajothy]

In the most cases in enterprise deployment, mostly we uses the VIP/HostName
compare IP. In that case does it support HostName/VIP?

Re: [Dev] [Mesos artifacts] Deploy script is failing to check database service

[Pubudu Gunatilaka]

Hi Akila,

Yes we faced several issues related to this. Apart from what you have
mentioned, we encountered mysql app name is not getting resolved. This
could be the delay in updating Mesos DNS. For these issues we looking into
following options.

*Option 1:*
Use a sleep before deploying a carbon server. Not the best option.

*Option 2:*
Depend on the health status results.

Currently, we do use a health check for mysql apps. Using dcos CLI we can
check the status of the app whether the app is alive or not. But this
cannot guarantee the DBs are ready to serve requests and Mesos DNS is
updated.

Thank you!

[Dev] [Mesos artifacts] Deploy script is failing to check database service

[Akila Ravihansa Perera]

Hi,

When deploying services to Mesos, the deploy script checks whether port is
open in marathon-lb. But this check fails to identify whether MySQL DBs are
up and running. We might have to figure out a way to handle this. Because
of this issue, the product fails to startup since databases are not ready
to serve requests. The product deployment needs to be on hold until all
databases are ready serve requests.

Thanks.

Re: [Dev] Clarifications on CEP HA Mode Deployments

[Ramindu De Silva]

Hi Isuru,

Please find the explanations inline.

In a two node HA cluster, in the eventSync/hostName configuration
(event-processor.xml), do we need to provide the own host IP? If so, how
does each nodes discover each other for event synchronization purpose? For
what exact purpose this eventSync configuration is used?

The provided host IP will be saved in the Hazelcast map after getting the
server's state (passive [1] / active [2] ). So the other members which are
in the cluster can get the relevant configuration using the passive key and
active key.


If we add a presenter node in addition to the two worker nodes, I assume we
should point to the presenter node from the both worker nodes. As per the
configuration, seems this is a TCP level connection. Why do we need a TCP
connection to the presenter?

In, HA configured serves, each and every server contains the same
artifacts, even the presenter node. But the presenter node only publishes
the output which has been already processed by the active node which is
received using the tcp connection [3].

FYI, the active node also sends the events to the passing node using the
tcp connection, and the events will be processed in parallel but the
passive node will drop the events from publishing or sending to the
presenter node (if available).

Hi Pushpalanka,

Thank you for the comments, I'm currently looking into Swagger
Since it's already used in WSO2 API Manager, can i know if it's built on

introducing new ones. I found Swagger2Feature [1] library as in the Apache
CXF documentation.

Hi Prabath,
Sorry i'm not familiar with those mentioned, can you clarify a bit more, I
would like to help in making any improvements

 Adding to this. Figure out a way to drop null values from the JSON
 response with Jackson level configurations. Also have a look at XACML JSON

Re: [Dev] [Mesos artifacts] Deploying wso2das 3.x.x on Mesos

[Niranda Perera]

Hi Akila,

Yes, there is a possibility to use a custom member discovery schema for
Spark. In fact, that is what we are using at the moment. We are using
Hazlecast for membership management (using WKA).
We are extending the following extension points in Spark [1] to support
this.

I agree with Imesh. We still have not extensively tested connecting DAS to
an external Mesos Spark cluster. But it is in the roadmap and we are
working on it.

 Hi,

 Deploying wso2das in Mesos is bit tricky due to lack of overlay network
 support in Mesos OOTB. This is mainly because Spark cluster (when running
 in Spark cluster mode) is unable to communicate through Docker IP addresses
 when they are assigned to different host machines in a multi-node Mesos
 deployment. I checked the config options in [1] and tried setting
 SPARK_PUBLIC_DNS parameter to Mesos host IP without any success.

 The main problem is there is no way to instruct Spark members to bind
 to the local Docker IP and advertise a different IP (Mesos slave host IP)
 to other members.

 @Niranda, Nirmal: is this something we can fix from our side? AFAIU, we
 are using Hazelcast to discover Spark/wso2das members and adding them to
 Spark context, right?

 On a side note, there is a Wiki page explaining how Spark should be
 used with Mesos in [2]. This is available after Spark 1.2.0. In this
 approach, we treat each Mesos slave as a Spark member and Spark/Mesos
 driver can directly schedule tasks on Mesos slaves instead of running Spark
 itself as a container. We should consider this approach in our C5 based
 efforts. We can leverage Kubernetes in the same way.

 IMO, we should recommend users to use wso2das in Spark client mode on
 Mesos due to these complexities.

 There is a DCOS Mesos framework for Spark [3] which can be used to

Re: [Dev] [Mesos artifacts] Deploying wso2das 3.x.x on Mesos

Hi Akila,

IMO it would better to use Spark Mesos Framework on Mesos DC/OS for
production deployments rather than trying to cluster the built-in Spark
module on Mesos. Then we might not need to worry much about this problem.

None production environments such as Dev should be able to use a standalone
DAS server with a volume mount with auto healing. WDYT?

Thanks

Re: [Dev] [ES]Error when Importing Users in Bulk through management console

[Dilini Gunatilake]

Hi Kasun,

I have tried bulk importing in ES 2.1.0 and it is working for me. May be
the format of the file you have used is incorrect. You can find the correct
format from [1]. I used the same file attached in the JIRA (names_2.csv).

Dilini

[Dev] How do I create a cache instance that's local to the JVM?

[Nuwan Dias]

Hi,

How can we create a cache instance that's local to the running JVM? I tried
using a cache name which has a prefix as "$_local_$.", but it doesn't seem
to work. Meaning that when I have two nodes in the same cluster, when the
cache is created on one node, the cache get I do on the other node returns
the cached object. Which means that this cache is still a distributed
cache. Is there anything wrong I'm doing or any other ways to achieve
$subject?

The code I use to get the cache instance is as below.

Caching.getCacheManager(

APIConstants.API_MANAGER_CACHE_MANAGER).getCache("$_local_$.GATEWAY_TOKEN_CACHE");


Thanks,

NuwanD.

[Dev] "Error 403 - Forbidden" when session expires in admin console

[Hasintha Indrajee]

Hi all,

When trying to perform operations through admin console, once the session
is expired we are getting a 403 from admin console. Seems like this occurs
due to CSRF filter blocking the request since the session is no longer
available at the server side.

[2016-07-06 15:34:27,576]  WARN {org.owasp.csrfguard.log.JavaLogger} -
potential cross-site request forgery (CSRF) attack thwarted
(user:, ip:127.0.0.1, method:POST,
uri:/carbon/userprofile/set-finish-ajaxprocessor.jsp, error:request token
does not match session token)
