this is a straightforward question about my work on your SOA architecture.
I noticed that if I login into a console (for example https://localhost:9443/carbon/, where is my ESB), and then login into another console (for example https://localhost:9444/carbon/, where is my BAM), the first crashes (bringing me to the login page), even if the user is different.
Do you know if and how it's possible to keep on two different consoles (belonging to two different architecture components)?
Thanks again
I checked the "remember me" option in both consoles and worked fine
I hope you have properly set the port offset value in the ${carbon.home}/repository/conf/carbon.xml file of the 2nd server. Can you please post here the error log of the failed server?

I'm hosting a website serves global regions, and recently there's a weird issue came up.
Already checked other posts on the Internet including the one in stackoverflow with a lot of discussions:Chrome net::ERR_HTTP2_PROTOCOL_ERROR 200 after a reconnect , but none of the answers helped.
Website is building on ASP.NET webform legacy "website" (not web application).
There's a important function which performs several process once user click a button on website.
Let's say there are 100 lines of code in that function, and I've added some flags to log which steps have been hit and processed.
Weird situation is:
Only China users are facing the issue. (website is not hosted in China)
Some users are using firefox and it returned below, in English it is "Secure Connection Failed"
But checked several posts including firefox documents, there should be error code on screen like
ssl_error_no_cypher_overlap but there is nothing.
Firefox error
Some users are using other browsers which is Chrome based, it returns:
Chrome error
In additionally, I checked the process log in these user feedbacks, most of them does not finish all the code, in other words, if there are 100 lines of codes and some of them just stopped in line 50.
Website has TLS 1.2 enabled, also http2 protocol (h2) is applied when I checked via Chrome-Network tab.
I'm wondering if it is possible if client browser shut down the connection in some reasons, it will end with the result I see (stopped at the middle of entire code flow), from my opinion if a request is posted to server then no matter what client does, the process should finish entire flow.
Any ideas or thoughts will be appreciated!
I was just dealing with that exact situation.
From what I read in various posts on the HTTP2_PROTOCOL_ERROR, I think what happens is the response is started but code problem(s) prevent the server from completing the response. The incomplete response gives the protocol error in Chrome, and, because it's over TLS, Firefox sees it as a security error. (I'd share links, but I've already closed all those windows - sorry.)
Somehow my code was preventing the server from completing the response without causing an exception.
I was able to track down the offending code by commenting out the body of every code-behind procedure on the page and then bringing them back one at a time.
Good luck to you!
I can't give you a concrete example, but in my case, there was no problem on the application side.
Have you recently added settings to your in-house infrastructure engineer?
For example, have you added WAF settings? You may want to check.
FYI
I have a website deployed in IIS (local network). If I use the IE browser in IIS Server, it takes less than 10 seconds for 1 page.
But if I access from another PC (in local network - 1Gbps). It takes 3~4 minutes. Could anyone give me some advice? Thanks
Capture a FREB trace on IIS. Follow this article - https://blogs.msdn.microsoft.com/amol/2009/04/01/freb-failed-requests-tracing-in-iis-7/
Under step 2, instead of adding the status code as 404.2 as mentioned in the article, please add 200-999. Also, as the next step, you will have to select trace providers. Select everything here or leave it to default.
Once the rule is enabled, try accessing the application from a client and reproduce the issue. Go back to the location where FREB was saved. If there are multiple files created, be patient and look for the one with the requested page and observe the time it took.
Open this file in IE and click on compact view. On the right hand side, you will see the time spent by the request in each module. Keep scrolling down until you see a jump in time there. The module where you see there is a jump is the culprit in your case.
I found the issue, it related to driver of my network adapter. It work after I turn off checksum following this post: https://superuser.com/questions/961617/how-to-disable-checksums-on-ethernet-card-in-windows-10
Is there a way to check the status of the Nest servers?
They appear to be down right now. Currently I'm checking by firing a GET request to:
https://developer-api.nest.com/?auth=...
Which works fine, I can just set a timeout and check the status codes.
I'm using the Firebase API (OS X) and I'm wondering, maybe there is a better way I can check? I don't see anything in their API. observeEventType:withBlock:withCancelBlock: never gets called.
Also, will the firebase observeEventType: block automatically start being called once the servers are back?
After 2 days the block appears to be lifted. I tried contacting Nest 2 days ago and I never got a reply. Perhaps they lifted the block and didn't reply, or it happened automatically.
I believe I was blocked because I was using my real account, with a real device. And obviously because I was in development I was logging in/out and changing values a lot.
I didn't realise until after the block you can create virtual devices (on a new account). More information here: https://developer.nest.com/documentation/cloud/chrome-extension
Moral of the story: use virtual devices!
My script searches for different strings in different tabs of a browser. Is there a way to keep the browser open after test execution is over so that results can be checked at a later time? Currently the browser closes automatically after 5 mins even though i am not using driver.quit().
Selenium: 2.33, Win 7, FF and Chrome
I don't know if you can let the browser open. But may I suggest you to use the TakeScreenshot functionality of Selenium in order to save the state of the browser when you want. That could help you to debug or to check that the page is as expected.
If this solution doesn't help you, could you please explain us exactly why you want to keep the browser open?
I was able to get the fix at least for my problem. I am using Remote Web Driver class and there is an option to provide timeout and browser_timeout parameters on the command line when the hub is started. Setting the value to 0 means the hub will wait indefinitely. For this scenario i wanted that only.
while 1==1:
pass
This will put your code into a loop, browser will stay responsive, and you ultimately kill the python program with control C. Just did this for the scripting of logging on to an application with encrypted credentials stored locally. This keeps plain text user ids and passwords out of the scripting code.
we recently migrated our application (IIS Server + DB Server) to AWS and also modified the network architecture a little bit. The entry point of the system is an Astaro Firewall (we use the AWS AMI) which also host the SSL certificate of the web server. Everything related to the firewall has been done by a vendor and we only have some read-only privileges.
We are getting 403 errors in a few situations but I will explain one, as they all may be related.
We got a form which query the database and return a report in HTML format (this report also have some checkbox to do updates). The first time the form is submitted, we always get the report back. If we wanna post the form again, updated with new data, it crash, returning error 403. We noted that it doesn't crash when the first results returned a very low number of rows (or none).
Looking at the details of the POSTs in Developer Tools, what seems to be the only difference between a working and 403 error reply is the size of the data posted. The second post is always bigger because it contains the data of the first report (as the page have also other option to checkbox the rows).
Also, looking at the IIS logs we don't see any traces of the POST that crash. Nothing at all.
This problem happen only in production. In dev environment it's all working flawlessly. The only difference is that the production have the firewall/ssl, while development is all open. This is why we think it may be related to SSL.
The vendor is not the most helpful, we are looking for help to pinpoint the issue and trying to take the situation in our hands.
Any input appreciated.
