Re: [Dev] [AppManager] Getting an exception when logging into the app store

[Dinusha Senanayaka]

Hi Kasun,

Haven't seen this issue in App Manager released pack which has
'org.jaggeryjs.hostobjects.web_0.9.0.ALPHA4_wso2v4.jar'. But seems EMM pack
is having org.jaggeryjs.hostobjects.web_0.12.0.jar.

This might be the reason as given in this thread.  "[Dev] Login and Logout
error in Store". Can you test the fix provided by Manu there.

Regards,
Dinusha.

+1 for deprecating POJO Mediator. ​The problem I find with the above
approach is that - there is an alternative way of doing it (using class
mediators). Not having multiple options (to do the same thing) in a
configurational language makes it easier for development, maintenance,
training etc. An example will be - POJOMediator can use expressions where
Class mediators you can't (making things confusing). It's better to push
the point home saying - the way to write custom code in the ESB (if you
have to) is using a class mediator and the message context api.

Apart from that - I believe in the POJO mediator we create multiple objects
in the heap? Where as in the class mediator we just create once instance.
Am I correct on this observation?

I am -1 for deprecating Db mediators. Like Malaka said, they are very
useful in scenarios where people want to connect to databases (also can be
used in conjunction with cache mediator for performance).

 I've found DBReport / DBLookup to be quite useful for simple DB

 limited in it's ability to only being able to return a single row of data,
 DB Report mediator is still quite useful in writing to a database,
 especially when we use a DB as part of the mediation sequences.

 I also feel it is worth continuing with POJOCommand, as it is the most
 simplest way of executing some custom code as part of a sequence. Although
 it is possible to do the same with a Class mediator, one doesn't have to
 worry about adding the proper jars, working with MessageContext etc. with
 the POJOCommand. I think we should retain it for the sake of simplicity of
 use.

 I'm +1 to deprecate the rest of the mediators.

[Dev] [DAS] Real time analysis or batch analysis ?

[Rushmin Fernando]

Hi Devs,

I need to address the following requirement.

---

A server sends events upon each request, to DAS.

There should a dashboard to show the number of request in each second.

---

Since the time gap is small I am under the impression that batch analysis
is not the best fit.

How can we address a requirement like this ? Real time analysis would help ?

Thanks
Rushmin

Re: [Dev] [DAS] Real time analysis or batch analysis ?

[Rushmin Fernando]

Thanks Suho !

Is it time window or time batch window ? How can we get the time points to
plot.

e.g. 12.01 - 2
   12.02 - 5
   12.03 - 3

And the function should be *count()* right ? :-)

[Dev] [DEV][DAS]Null pointer exception while executing a schedule task in DAS HA cluster.

Hi DAS teaam,

I am getting below null pointer exception while trying to execute a

tried to run this example[1]. It has a scheduled task. However, this error
can not be observed in a single node fresh pack.

The error is,

Re: [Dev] [DEV][ML] Error with Kdd cup 1999 data set

[Nirmal Fernando]

You seem to have a categorical feature with 1 unique value. Can you check
your categorical feature list?

[Dev] ESB proxy service for mix of TwoChannel and InOnly operations

[Ayoma Wijethunga]

Hi All,

This is relevant to WSO2 ESB 4.9.0.

In WSDL attached [1
],
there are five TwoChannelAxisOperation(s) and one InOnlyAxisOperation. In
such situation, if we create a single proxy service in ESB with
configuration [2
],
InOnlyAxisOperation will fail with below exception :

ERROR - NativeWorkerPool Uncaught exception
> java.lang.UnsupportedOperationException: An access occurred that is not
> valid.
> at
> org.apache.axis2.description.InOnlyAxisOperation.getMessage(InOnlyAxisOperation.java:117)
> .
>

​​It was observed that it is possible to use "OUT_ONLY" and
"FORCE_SC_ACCEPTED" to correct this [3
]
[4
].
But relevant transport property applies to endpoint, resulting in
TwoChannelAxisOperation to fail if applied.

When creating proxy service for a web service, what is the best practice to
follow in order to avoid this type of problems?
Do we create,

   - separate proxy services for each set of operations
   - use "switch" or "filter" mediator in the "in sequence" and "send" to
   OUT_ONLY endpoint depending on operation

or what is the best path to follow?

Re: [Dev] [DAS] Real time analysis or batch analysis ?

[Tharik Kanaka]

Hi Rushmin,

As suho has mentioned you can write a siddhi query with a window or even
you can use a rate limiter and count number of events then write it to an
output stream. Same kind of scenario is explained in this blog post [1]
where in that blog it is calculated the average but in your case it needs
to be count.

In the dashboard when you are selecting x and y axes, select TIMESTAMP for
x axis and count for y axis. Chart is capable of identifying TIMESTAMPs
seconds and plot them in X axis.

 Hi Devs,

 I need to address the following requirement.

 ---

 A server sends events upon each request, to DAS.

 There should a dashboard to show the number of request in each second.

 ---

 Since the time gap is small I am under the impression that batch
 analysis is not the best fit.

 How can we address a requirement like this ? Real time analysis would
 help ?

 Thanks
 Rushmin

[Dev] [DAS][Documentation] Incorrect documentation - Retrieving the Total Record Count of a Table via REST API DAS

[Rajeenthini Satkunam]

Hi all,

I have tried to invoke REST API through POSTMAN(Chrome) for DAS getting the
record count of a table.I have followed the documentation here[
https://docs.wso2.com/display/DAS300/Retrieving+the+Total+Record+Count+of+a+Table+via+REST+API]
.It gives me a 200 OK success response but it always returns -1 as a
response.


​
But I have tried this below way and it is working fine for me.Hope the DAS
documentation of REST API wants to be update along with API changes.

*METHOD* : POST

*URL* : https://localhost:9443/analytics/search_count

*BODY* :
{
 "tableName":"sample2"
}

*HEADERS* :
Authorization : Basic YWRtaW46YWRtaW4=
Content-Type : application/json

This REST API request gives me 200 OK success response as a count of
records in a particular table. I have inserted the screenshot of my POSTMAN
request and response for further more idea.

*Thank You.*

Hi,

@Vinod, I used the format given in the Activiti rest api documentation to

@Nuwan, I have updated the user guide with the response codes and the
sample success responses.

Re: [Dev] [DAS] Error reading from RDBMS

[Niranda Perera]

Hi Rukshan,

as per our offline discussion yesterday, this is due to, spark jdbc
connector not being able to handle the ShortType. As a workaround, is the
migration process, you might have to add a script to alter the table schema
in RDBMS and then take it back using the connector.

Hi Niranda / Inosh,

Thanks a lot for the quick call and reply. Yes issue seems to be fixed now.

 Hi DAS teaam,

 I am getting below null pointer exception while trying to execute a

 tried to run this example[1]. It has a scheduled task. However, this error
 can not be observed in a single node fresh pack.

 The error is,

[Dev] Governance Registry - What means these double curly braces in hbs files and how does it work ?

[Arnaud Charpentier]

Hi,


We are new to UI development of governance registry and are trying to 
internationalise some text of the publisher.

We've tried to pass JS var from the server side to the client with jquery but 
it doesn't work. It seems that we should use the syntax with double curly 
braces as is done in every hbs files.


But our problem is that we can't understand what are all these double curly 
braces. We've done many researches and tests but we're not able to figure out 
how does it work.

Is that an existing web technology or a mechanism that WSO2 has created ?

If this syntax was specifically created by WSO2, is there any documentation to 
help us on this subject ? Or could you explain us briefly how does it work ?



Regards

Re: [Dev] [DAS][Documentation] Incorrect documentation - Retrieving the Total Record Count of a Table via REST API DAS

 Hi all,

 I have tried to invoke REST API through POSTMAN(Chrome) for DAS getting
 the record count of a table.I have followed the documentation here[
 https://docs.wso2.com/display/DAS300/Retrieving+the+Total+Record+Count+of+a+Table+via+REST+API]
 .It gives me a 200 OK success response but it always returns -1 as a
 response.


 ​
 But I have tried this below way and it is working fine for me.Hope the
 DAS documentation of REST API wants to be update along with API changes.

 *METHOD* : POST

 *URL* : https://localhost:9443/analytics/search_count

 *BODY* :
 {
  "tableName":"sample2"
 }

 *HEADERS* :
 Authorization : Basic YWRtaW46YWRtaW4=
 Content-Type : application/json

 This REST API request gives me 200 OK success response as a count of
 records in a particular table. I have inserted the screenshot of my POSTMAN
 request and response for further more idea.

 I reproduced the error. If we set carbon.spark.master.count value to 2
this error will occur. Any solution available in this case?

Re: [Dev] [DEV][DAS]Null pointer exception while executing a schedule task in DAS HA cluster.

[Niranda Perera]

Hi Roshan,

This happens when you have a malformed HA cluster. When you put the master
count as 2, the spark cluster would not get initiated until there are 2
members in the analytics cluster. when the count as 2 and there is a task
scheduled already, you may come across this issue, until the 2nd node is up
and running. You should see that after sometime, the exception gets
resolved., and that is when the analytics cluster is at a workable state.

But I agree, an NPE is not acceptable here and this has been already fixed
in 3.0.1 [1]

as per the query modification, yes, the query gets modified to handle multi
tenancy in the spark runtime.

hope this resolves your issues.

Also, search count always work, because it is the indexing based search
count, and that will always return the count.

Re: [Dev] [DAS][Documentation] Incorrect documentation - Retrieving the Total Record Count of a Table via REST API DAS

[Anjana Fernando]

Hi,

Getting the record count from direct analytics tables are disabled by
default from the RDBMS connector. This is basically an optional
functionality, and when that happens, it will return -1. @Rukshani, please
mention this properly in the docs. I remember this issue was raised earlier
also, and maybe we mentioned it in some other place in the docs.

Cheers,
Anjana.

Re: [Dev] [Builder] Jenkins build became unstable: product-as #802

[Manuri Amaya Perera]

Here what the failing test does is waiting for a web app to switch to ghost
mode and then sending a request. What should happen is once the ghost
webapp gets a request the actual webapp should be deployed and serve the
request. But here it seems that the request times out before the actual
webapp is deployed.

The fix would be retrying the request until a time limit exceeds.

Thank you.

Re: [Dev] Need help from DS team to fix Analytics Dashboard issues which are related to DS

[Anjana Fernando]

Also, these fixes need to be going with DAS 3.0.1, so we somewhat need
these fixes to be done as a minor release to the earlier DS feature
versions we used. Because, as I got to know from our last meeting with DS
team, you guys are working on a modified approach for the gadget generation
and all, which may not be compatible with our earlier model. @Sachith,
please follow up on this.

Cheers,
Anjana.

 Hi All,

 We have changed the kernel version of carbon-mediation and product-esb
 to 4.4.3 and ran all the integration tests for the product-esb. We didn't
 encounter any issues after upgrading the kernel version.

 Thank you,
