Re: [Dev] [DAS] Inferring actual table name from the table's encoded name

[Sajith Ravindra]

Have to agree with Sinthuja on this.

IMO this is a simple utility function. People will be mostly using this
while debugging an issue to get the actual table name. Having script makes
things much easy and simple IMO.

@Gihan, Gimanatha:  But, is this a direct or intended use case of using
these two construts together. Isn't it more of a by product?

If some user wants to process only subset of data wouldn't the user use a
"WHERE" clause?

[Dev] [DAS][Spark] Is it valid to use INSERT OVERWRITE with incremental processing?

[Sajith Ravindra]

Hi all,

Can there be a valid use case where we do an INSERT OVERWRITE to a table
and then do incremental table commit?

AFAIU, it leads to loss of data as incremental processing processes only
unprocessed data and OVERWRITE statement drops previously processed data.

Please advice.

Currently common we share the common gadgets among ESB and APIM dashboards.
Therefore we provided a mechanism to specify product specific settings, you
can think of it as a profile. That's the reason why you need to specify the
gadget type. In your case, the gadget type is used to the load the server
URL  (ESB and APIM have different URLs for the log-analyzer-proxy.jag).

In many cases even we can share the gadget among the two products,
sometimes we need minor changes in each product when displaying the
gadget(e.g. a column name in a chart). Such options are provided through
the gadget type.

Ideally, we should have a type called "common" where you can use when no
customizations are required + product specific types to customize the view
of the gadget when necessary.

IMO, these gadgets shouldn't load based on the Gadget Type attribute since

I agree that we need to re-organize the gadgets and provide with a generic
feature for products where they can build upon. But this requires some
considerable effort as per the current state. We will be working on this
once the ongoing efforts on ESB and APIM is over.

Re: [Dev] [DAS] Using a filter in event receivers to validate incoming data stream

[Sajith Ravindra]

Hi Dinesh,

I'm afraid you can't do that in the event receiver itself. Event receivers
will pass all the events for processing without doing any filtering.

You can do this with a simple Execution plan. Please refer[1] on the regex
extension for siddhi.

Re: [Dev] [CEP] wso2 cep java.lang.OutOfMemoryError: GC overhead limit exceeded

[Sajith Ravindra]

Hi Charini,

How large are these events ? It's unlikely that Max attribute aggregator
has caused this since it only keeps the values. The most probable reason is
memory is not enough to hold the 3min window. We should be able to confirm
this by analyzing the generated hepdump.

As Abimaran has mentioned you should be able to overcome this issue by
increasing the Xms and Xmx values. I assume you have used the default
values for Xms and Xmx.

Re: [Dev] [DAS][IS-ANALYTICS]May threads are blocked on Event Sink Queue

[Sajith Ravindra]

Gihan, it's true that IO for database operations is also a bottleneck. But if 
you take a look at the thread dump many data receiving threads(to persist 
events of incoming streams) and processing threads (to persist events of output 
streams) are just blocked on this lock trying to insert events to the queue. 
From what I see it's not that threads are blocked because queue is full.

Apparently at this point, blocking of these receiving and processing threads 
seems to degrade the performance.

[Dev] [DAS][IS-ANALYTICS]May threads are blocked on Event Sink Queue

[Sajith Ravindra]

Hi all,

We are doing a performance test on IS analytics server. While we keep
pumping data to the server we can see that throughput gradually decreases
to a very low (< 1K) TPS. We used MySQL with InnoDB with tuned parameters.
And set Xms2g and Xmx4g in DAS.

When looked at the thread dumps we can see that more than 100 threads
BLOCKED/TIMED_WATING at AnalyticsEventQueueManager.put() on a single lock
object(i.e. on the same reference). Many threads are just waiting to get
the lock without processing events which seem to be the reason for degraded
performance.

Are there any parameters that we can tune to gain better performance to
overcome this bottleneck ?

I had a look at the code and AFAIU all events of a particular tenant are
persisted through a single synchronized queue. According to my
understanding, this synchronized queue is a performance bottleneck since
all threads pertaining to a persisted event stream will need to block on
this queue.

IMO if we can have a queue per event-sink(i.e per persisted stream)  it
should give a better performance than this. Any implications if we do that
or is there a better option?

Re: [Dev] [DAS] java.lang.NoSuchMethodError when trying to add Kafka Event Receiver

[Sajith Ravindra]

It seems Spark has a dependency on scala-library_2.10.4 and this jar is
already included in DAS pack, therefore copying scala-library-2.11.7.jar as
per the documentation will lead to a conflict. I tested deleting
./repository/components/plugins/org.scala-lang.scala-library_2.10.4.v20140209-180020-VFINAL-b66a39653b.jar
in DAS pack and it fixes the above error. But it give a NoClassDefFound
error in startup.

AFAIU there's no straightforward way to workaround this issue as it
requires to two different versions of the same .jar other than upgrading
the Spark scla-library dependency.

P.S : @Charith if this is for the sake of testing you can use CEP as it has
not scala-libarary dependency.

Re: [Dev] Can we use puppet scripts in wso2/puppet-modules for CEP for a distributed deployment ?

[Sajith Ravindra]

Hi Imesh/Isuru,

I submitted the pull request[1] sometime back and it has implemented all 3
patterns of CEP (standalone, HA and distributed). Please let us know if we
can provide any further assistance on this. It would be great if we can get
the distributed deployment scripts also in wso2 repo because manually doing
the distributed deployments requires some effort compared to other two
patterns.

[Dev] Can we use puppet scripts in wso2/puppet-modules for CEP for a distributed deployment ?

[Sajith Ravindra]

Hi Imesh,

It seems we have still not added the capability to deploy CEP in storm
based distributed mode using the puppet scripts in [1]. Am i missing
something here? or are we still in the process of merging the changes? Is
there anything that needs to be done from CEP team to get distributed
deployment related changes merged to [1]?

Re: [Dev] CEP does not accept requests after receiving a high rate of events for some time

Currently we don't have queue sizes as metrics in Siddhi, but we do have,
- throughput per stream
- per query latency
- per query memory consumption
as metrics in Siddhi.

I think as Mohan mentioned we can use those for identifying the hotspots.
But it's included only in CEP 4.1.0

Re: [Dev] Handling time-consuming processes within Carbon Metrics Gauges

[Sajith Ravindra]

I think it will be a good idea to run several rounds of testing to see if
this memory calculation is CPU intensive. And If this is CPU intensive then
this might have an adverse affect the overall performance of CEP/Siddhi as
well when executing in a limited resource setup.

Re: [Dev] Handling time-consuming processes within Carbon Metrics Gauges

[Sajith Ravindra]

Hi Granier, Suho

The memory calculation will be a time consuming issue since it has to
traverse through the complete object tree. IMO, we should have the option
of executing matrix calculation in a separate thread and report back to the
caller with the result.

I think it's a valid case to have matrices which consume time/resources to
calculate. Therefore, it will be a good idea to make available the option
of matrix calculation to be asynchronous and report back once done in
carbon metrics library it self.

WDYT?

Re: [Dev] Exception while reading time format in CEP

[Sajith Ravindra]

Hi Yasara,

Apparently, there's a problem with your time stamp

Wed Aug 27 13:08:45   2008

it does not have the sign(+/-) in timezone. It should be corrected as
follows,

Wed Aug 27 13:08:45  + 2008

Please refer
http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
for the acceptable formats.

Apparently the port 8905 <http://192.168.48.128:8905> is already in use by
another process. Please check if there's another process listening on port
8905.

Hi Shavantha,

Can you please check and confirm that *192.168.48.128 *is the IP address of
the host which you are trying to start the manager service. You can use
ifconfig for it.

Re: [Dev] Issues in setting up distributed mode deployment for CEP

[Sajith Ravindra]

To add to Lasantha's comment on point 2

2) After starting the STORM cluster, CEP managers and CEP worker node, We
couldn't see anything on the STORM UI under topology. Does that mean
cluster is not setup correctly?

You can verify if the cluster has setup correctly by logging in to storm
UI. You should be able to see the information of nimbus and all supervisors
listed. And also please verify that the IP address of nimbus has been added
to repository/conf/cep/storm/storm.yaml of CEP manager node.

[Dev] Don't we use db scripts in dbscripts/identity anymore?

[Sajith Ravindra]

Hi,

With the latest build[1] of CEP we observed that dbscripts/identity
directory is not created. Don't we use db scripts in dbscripts/identity
directory anymore?

[1] -

Re: [Dev] What should be the 3rd parameter of login in AuthenticationAdminStub?

Thanks for the explanation. I think it's better to correct the same for
documentation for IS 5.0 documentation as well if it's same for the IS 5.0
as well.

[Dev] What should be the 3rd parameter of login in AuthenticationAdminStub?

[Sajith Ravindra]

Hi IS Team,

I was referring [1] and when going through the code sample provided I
noticed that the 3rd parameter passed to the login of
AuthenticationAdminStub is not hostname/ip-address of the client.

authstub.login("admin", "admin", APP_ID)

Is this correct? If it's not hostname/ip-address what should be it?

Please advice.

Re: [Dev] Documenting Siddhi Extensions

[Sajith Ravindra]

Shouldn't we describe the parameters. For an example what are the possible
values the range, what are invalid parameters(may be with an explination).
I think it will be usefull for complex extesions.

[Dev] Error while trying to install DSS feature 3.2.1 to ESB 4.8.1

[Sajith Ravindra]

Hi all,

Following error is shown when trying to do the $subjuect from
http://dist.wso2.org/p2/carbon/releases/turing/.

Your original install request has been modified.
org.wso2.carbon.ndatasource.feature.group-4.2.0 is already installed, so an
update will be performed instead.
org.wso2.carbon.ndatasource.ui.feature.group-4.2.0 is already installed, so
an update will be performed instead. Cannot complete the install because of
a conflicting dependency. Software being installed: Data Service Hosting

But, I had a backed up  repo of truing branch and when I tried installing
the same feature from the backed up feature and it worked.

Any advice on the cause of this?

[Dev] [ESB]Setting messageType=application/xml removes SOAP envelop of the response sent to client

[Sajith Ravindra]

Hi all,

In sample 150 of ESB 4.8.1 , when messageType property is set to
application/xml in the outSequence, in the response sent back to the client
SOAP envelop is removed even the backend sends it's response wrapped in a
SOAP envelop,  response sent to the client is as follows,

[2014-12-29 19:12:18,730] DEBUG - wire << "http://services.samples";>http://services.samples/xsd";

And when messageType=text/xml it does not remove the SOAP envelop and
response sent to client as follows,

Can someone please describe this behavior? why setting
messageType=application/xml removes the SOAP envelop from the response sent
to client?

Thanks in advance

There is a equivalent for JSON in script mediator, it's getPayloadJSON().
You can refer [1] for an example on converting JSON to XML.

Re: [Dev] error in pom.xml when creating a carbon component service stubs

[Sajith Ravindra]

Hi Shasika,,

Adding  to m2e pluing configurations in your pom.xml for
maven-antrun-plugin with  as  should fix your problem.

E.g:

  
  org.apache.maven.plugins 
 maven-antrun-plugin 
  [1.1,) 
 
   run

Re: [Dev] Generting a Unique-ID from a Unique String

[Sajith Ravindra]

Hi Lakmali,

If this is not for a encryption purpose I think it's better to use Base64
encoding. As per the description i feel that what you are trying to do is
encoding rather than encrypting. Also you can decode it back if you want if
you use Base64 encoding.

Thanks

Re: [Dev] How do we verify a license file shipped with a product?

[Sajith Ravindra]

Hi All,

Under C5 Development governance we have developed a maven plugin to
generate license.txt file. It's not possible to consideraautomate the
process 100% since it's not possible to determine license information of
some dependencies and it will be required feed such information manuallly,
but still the plugin has automate the process to a considerable extent.

Re: [Dev] Generating LICENSE.txt (C5 development governance)

[Sajith Ravindra]

Hi all,

In the approach described in previous mail information related to JARS In
product packs are stored in repository as 'Modules' and 'Artifacts'. But
there are jars generated using 'ant'. 'Artifacts' and 'Modules' of C5
governance solution are intended to store information of maven projects and
dependencies. Therefor, it's not possible to store information of jars
generated using ant through an 'Artifact' or 'Module'.

Please  provide your suggestions on how to handle such jars when storing
information and generating LICENSE.txt.

A tentative approach would be,
- Having another RXT called 'Other Dependencies'(with contains file name,
license type)
- Recored information of non maven dependency jars using it when executing
'licfill' goal
- And, fetch information from the repository when executing 'licgen'

or else,
We cant store information of such jars in another data store(e.g. my sql)
and fetch information from there when generating the file.

[Dev] What JARs should be considered when generating LICENSE.txt for a pack?

[Sajith Ravindra]

Hi All,

When generating LICENSE.txt for a product pack is it required to consider
all the JAR files included in the pack. Or else is it only sufficient to
consider jars in /lib and /repository/components/*?

Also, in addition to jars should we also count other file types such as
.zip, .mar files?

Re: [Dev] Generating LICENSE.txt (C5 development governance)

[Sajith Ravindra]

Hi all,

For $subject for a product pack the following approach will be taken,

Following 3 fields will be added to the 'Artifact' and 'Module' asset types
- JAR Name - Name of the .jar file generated for maven project or the .jar
file of the dependency
- License type
- Packaging type - Can be jar,bundle or jarinbundle

Two goals will be added to the governance maven plugin. These goals must be
executed against the root pom.xml of the product.
- licfill - Feed the license information to the GReg.
- licgen - Generate LICENSE.txt.

The purpose of having two swperate goals is to allow generation of
LICENSE.txt files without requiring to updating license information every
time when generating the file.

To feed license information to the GReg, the plugin will scan through the
pack to locate jars and to read their pom.xml files .'Artifacts/Modules'
are mapped to jars using information read from the pom.xmls of jars. In
this process,If there is an 'Artifact/Module' for a given jar in repository
it will be updated with license information. Otherwise, an 'Artifact' will
be created to represent the jar(dependency). To retrieve license
information of jars [1] will be used.

When generating LICENSE.txt, plugin will scan through the pack to locate
pom.xmls of jars inside the pack. Then it will read
groupid:artifactid:version from pom.xml and use that information as key to
get license information from Greg of each jar.

Please provide your feedback/suggestions on this approach.

[Dev] Generating LICENSE.txt (C5 development governance)

[Sajith Ravindra]

Hi all,

Under C5 development governance project we are planing to facilitate the
generation of  LICENSE.txt.

Up to now, we have implemented support for generating LICENSE.txt for a
single JAR(Carbon Feature) or a carbon component by looking at all its
listed dependencies in pom.xml files

Now we are trying to implement support for generating LICENSE.txt for a
product pack. Because a product pack contains jars that are not are not
related to dependencies in pom.xml files of the product, it's required to
scan through the pack to identify the jars. After identifying the jars, the
jars must be mapped to  Modules/Artifacts[*] stored in a Greg instance we
maintain in C5 development governance solution.

The problem we are trying to solve is, how the mapping between jar file
names and Artifact/Module[*] can be done properly?

Please suggest on a proper way you can think of to do this mapping.

[*] - In C5 development governance solution we use two types of RXT
artifacts to capture dependency information of a maven project. it contains
information such as group id, artifact id and version of a dependency
 (1) Module - refers to an internal maven project
 (2) Artifact - refers to an external 3rd party dependency.

[Dev] [Axis2] What's the Axis2 messageReceiver to be used for a operation with only return value?s?

[Sajith Ravindra]

Hi all,

When developing a web services using Axiom what should be the
messageReceiver  we should use for an operations which only returns a value
but does not take an argument?

It seems there's RawXML*OutOnly*MessageReceiver in Axis2. So are we suppose
to use RawXML*INOut*MessageReceiver and take an dummy argument or is there
another messageReciver to be used for such operation?

Thanks

[Dev] Eventing sample of DSS is not working

[Sajith Ravindra]

Hi all,

I was trying to run the eventing sample of DSS 3.1.1[1]. But it fails to
send the mail on events and it seems this is due to having a invalid mail
tranportSender configurations in *sample_axis2_client.xml.*

In the sample it says "*In order to allow mails to be sent, we have to
configure the mail sender in the client Axis2 configuration. A sample
axis2.xml file for the client configuration is stored at
CARBON_HOME/samples/resources/sample_axis2_client.xml. Use it to replace
the CARBON_HOME/repository/conf/axis2_client.xml file. The axis2_client.xml
contains an already configured mail sender section and is ready to be used.*
"

But actually, when the sample is executed with
*/samples/resources/sample_axis2_client.xml
*it fails to send the mail on  trigger. Then i modified the the mail
configurations to use wso2demom...@gmail.com, and then event mails were
sent successfully.

It seems */samples/resources/sample_axis2_client.xml *delivered with the
binary distribution needs to be corrected to have a working mail
transportSender configuration.

[Dev] Exception when running AS sample 1

[Sajith Ravindra]

Hi all,

I'm trying to run the sample 1 of AS 5.2.1 (
http://docs.wso2.org/display/AS521/Checking+the+Authorization+of+WebApp+Requests).


Once i run the example after following the given instructions, AS returns
responses for only two requests(i noticed that response for first request
is not what doc says it should be) and then throws an exception. The output
is as follows,




































*sajith@sajith-ThinkPad-T520:~/wso2as-5.2.1/samples/EntitlementFilter$
./run-client.sh Using CARBON_HOME: /home/sajith/wso2as-5.2.1Using JAVA_HOME

I followed below  steps to when setting up in addition to the steps
described in documentation
1) First i started the IS with default setting,
2) Started  AS with -DportOffset=100.
3) Changed run-client.sh to adjust the port
4) Change the remoteServiceUrl port to be 9443 in the web.xml of the
EntitlementFilter web app and deployed it with ant command.




*remoteServiceUrl
https://localhost:9443/services/
<https://localhost:9443/services/>*
Can someone please help me find out what i have done wrong here?

Thanks
