No synapse button in ESB 4.8.1 Management console - wso2

I downloaded WSO2 ESB 4.8.1 and started the wso2 server and got the management console up and running. But there does not exist a button called "Synapse" under the configure tab in the top left corner in the management console. I want it to open the synapse-configuration.xml to change the configuration to secure the service. Can anyone tell me why this "Synapse" button is not there in the configure tab in the ESB management console and hoe I can get it?

Use "Source view" menu. It will open the synapse-configuration.xml. See following image.

IIS Manager - Cant start W3SVC and IIS Admin is missing from Service

I am trying to start W3SVC on Windows 10 but I am facing several issues here:
I went to Task Manager and clicked the Services tab then I found the W3SVC service and I right clicked it and choose start but it did not start. I tried to click it several times.
I do have IIS Manager but IIS Admin is missing from Services which I do not know why.
World Wide Web Publishing Service is turned on and it is running automatically The dependencies tab have everything in there as it should be. HTTP Service and Window Process Activation Service
I did try to restart IIS in command prompt iisreset. But it failed and the error appeared:
The IIS Admin Service or the World Wide Web Publishing Service, or a service dependent on them failed to start. The service, or dependent services, may had an error during its startup or may be disabled.
I am trying to run a custom website I created on IIS Manager but it wont start. The error appeared:
Cannot start service w3svc on computer
I tried to start "World wide web publishing service", but I was unable to start it as it said:
Error 1068: The dependency service or group failed to start
I want to start the website that I created in my inetpub and I want this w3svc up and running
open Control Panel->Programs->Programs and Features->Turn windows features on or off -> Uncheck "Internet Information Services" and "Windows Process Activation Service"
Restart your machine.
open Control Panel->Programs->Programs and Features->Turn windows features on or off -> install both "Internet Information Services" and "Windows Process Activation Service"
if you still face issue then check the event viewer log.
Try this commands on cmd:
reg delete HKLM\SYSTEM\CurrentControlSet\Services\WAS\Parameters /v GenerateKeys /f
net start w3svc
net stop apphostsvc
net start apphostsvc

DSX: Cannot edit Jupyter notebook

When creating a new notebook, dsx fails when trying to connect to the Spark instance with the following error message:
Sorry, we could not start your service. Please contact support with
the following information: The service UUID could not be established.
Description: PUT /analytics/notebooks/reactivate?sparkService=&createTenant=true failed.
What can we do to resolve this?
Contact support. There's no obvious link, but your DSX account is backed by a Bluemix account and an Apache Spark service in Bluemix, so you can use the Bluemix support channels.
In DSX, click on the logged-in symbol in the top right corner. In the menu that opens, select "Settings". In the Settings screen, there's a button "Manage Bluemix Account", and below that a link "Contact Support".
Alternatively, a click on "Manage Bluemix Account" will take you to the Bluemix console, where you can use the "Support" menu.

Missing classpath entry carbon.home.folder\bin\org.wso2.carbon.bootstrap-4.2.0.jar

I just tried to deploy my configurations to wso2 ESB inside eclipse and I got a following error message while deploying my CAR file to ESB. How can I fix it?
First, you should point to the correct path of your WSO2 ESB instance (where the main folder is located). You can click the Browse... button next to the CARBON_HOME field and locate it.
Also, for WSO2 ESB 5.0.0, the correct version for the server should be WSO2 Carbon 4.4 based server.
You need to download WSO2 ESB 5.0.0. Go to here. Select WSO2 ESB 5.0.0 and download server. Then browse this directory to Eclipse. If you can't go next, cancel the process, try again. It should work.

WSO2 Developer Studio Proxy List

I am working through the "Cloud to RDBMS" example using wso2 developer studio.
At the bottom it says:
"Finally, to try the service, go to the proxy list and click try it
under Salesforce proxy."
I'm new with Developer Studio and cannot find a "proxy list" anywhere.
Does anyone know where to find it?
Finally, to try the service, go to the proxy list and click try it under Salesforce proxy.
It is not telling you to click "try it" on the developer studio. It is telling you to login to ESB management console (https://localhost:9443/carbon) and click "List" under "Services" from the main menu as shown below.
And click "Try this service" of the relevant proxy service to go to the "Try it" tool.
So you have to first have to deploy the proxy in ESB and try above steps. This article would be useful for you to start with.

Setting up WSO2 stratos on local computer

I downloaded the latest version of WSO2Stratos from the website and unzipped it on my local computer. I copy the text in the read me file to the /etc/hosts file.
When I run particular services e.g., manager, as, and ESB it works fine without an error.
When I use a browser to login to the page "https://localhost:9443/carbon/"
It works fine and possible to see the main page.
After this when I click on any option available, nothing working and I see a only blank page. When I click app manager, ESB or anything on the left side panel, I don't see another page. I see only the main page.
why I cannot see the services offered by stratos live.
WSO2 Stratos 1.6 version is more easier to install and configure. Refer to Insallation guide blog post here
It seems you have not enabled Single Sign On option in your Stratos setup.You need to add following entry to ~/.bashrc to enable SSO.
export SSO_ENABLED=true
The option Single Sign-On means that once a user logs in to a single service, eg: Stratos Manager using their credentials they will automatically be signed in to any other service eg: ESB or Governance.
Additionally this blogpost will help you.
