I am performing SendMessage operation in WSO2 EI 6.4.0 using AWS SQS Connector (V1.0.7).
Sometimes Message is not posted to AWS SQS Queue, got some ERROR/WARNING Message in Log mentioned below
ERROR Code from Log:
Error_code = 101506
or Error_code = 101508
Warning Message:
...ANSWER
Answered 2022-Feb-24 at 16:49Did you try to use a Message Store and a Message Processor to implement a Guaranteed Delivery System? You have to publish the message to a Message Store. A Message Processor can try to post it to the SQS. If it fails, it will be added to another Failover Message Store. We can add the message to the original message store after some time with the help of another Message Processor. This way, it will keep on retrying until it succeeds.
If this solution is too complex, you can go with your second option where you call the sendMessage Operation inside the fault Sequence.
QUESTION
in wso2am we can use message mediations in incoming requests and responses to process messages for different purposes. After I read micro integrator documentation, I believe that I can do whatever micro integrator is doing with its mediation sequences by the help of API manager mediations and it's confusing me because I don't know what is relationship between API manager and micro integrator. Are they two independent products? or API manager 4 has micro integrator inside? I would really appreciate helping me with any of my questions.
...ANSWER
Answered 2022-Feb-02 at 08:41APIM and MI both have mediation capabilities.
APIM has limited mediation capabilities compared to that of MI.
We use APIM (Gateway) to deploy light-weight mediations which are used in request/response transformations, processing etc. More complex mediations including service chaining, service orchestration, message stores/message processors, scheduled tasks, etc are kept with MI.
MI functions as an intermediate layer between the APIM gateway and backend server performing various complex mediation logics which cannot be performed by the APIM's mediation capability.
We expose rest apis from MI which are used as the backend endpoint in the APIM gateway through which we chain the request to the actual backend through the MI layer.
Consider an example of generating a response for an API request aggregating response from multiple backends. This can be achieved using the MI's complex mediation capabilities.

QUESTION
I'm using Facebook Audience Network in my application I don't want to use other ads networks. but Facebook introduces mediation bidding. In official documents of Facebook Audience Network they give us the option "only use audience network not bidding" when I choose this option Facebook did not give any ads response. If I use mediation then I want to use Audience Network as my primary ad network, not another network. Please help me if anyone has any information.
...ANSWER
Answered 2022-Jan-10 at 05:19After a long time and many experiments, I found some solutions to handle this situation.
First you can't add FAN as Primary Network. if you create ads id in
Waterfall
, not inmediation
, and implement directly you will see in the Facebook console "bidding request" option. Facebook says "Not gets bidding request" it will not activate ads in your application.If you want FAN as your Primary Network firstly you should do Mediation when facebook activate your request ads then shift to waterfall it will give you ads
In my case I have to implement Admob ads with the mediation of Facebook and FAN ads separately and control them with Firebase Remote Configuration. Now you have implemented two Ads SDK first is AdMob and the second is Facebook. When Facebook accept bidding request from AdMob then you just change ads from Admob to Facebook via Firebase Remote Configuration. Basically, you have two SDK implementations in your app.
This solution is for when you got limitations from Admob and want to run Facebook ads. Remote configuration is the best solution for the limitation of Admob networks. you can also remove limitations from AdMob by using different ads network and controlling them via remote configuration

QUESTION
I am just trying to post incoming payload to rabbitmq by using messageStore in WSO2 EI 6.6.0.
API-Code:
...ANSWER
Answered 2022-Jan-05 at 12:35If you want to send, just JSON message as payload to RabbitMQ, don't use message store. Message stores, are storing all synapse message context with payload for later processing - that is their purpose. So that is why you see in decoded RabbitMQ Payload not only the message, but also additional properties.
For sending JSON to RabbitMQ you can use just to a proper
endpoint
.
Look as this documentation sample.
I have also have made some sequance template
for more easy use of sending messages to rabitmq, so next you can may look at this helpful post, and adapt to your own needs.

Install mediation
You can use mediation like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the mediation component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
