Database diagnostic information on dashDB - ibm-cloud

I am trying to load some data into a table in my dashDB database but hit an error message. Can I download db2diag.log from the dashDB console to find out what has happened?
com.ibm.db2.jcc.am.SqlNonTransientConnectionException: [jcc][t4][10335][10366][4.18.60] Invalid operation: Connection is closed. ERRORCODE=-4470, SQLSTATE=08003 Data loading failed.

As Jeff said, you can't access the logs of this DBaaS as it is shared resource. You will need to debug from your applications side. Are you maybe having a contingency problem with passing around the connection handle? Can you share your code?

Since DashDB is a service, you don't have access to the logs that you normally would have access to.

Challenge in data from REST API using Azure Data Factory - access issue

We are trying to reach to an API hosted in our company network using rest connector in ADF (SHIR is used). Linked service connection is successful but dataset is unable to read the data and copy activity is as well failing with below error. Please suggest your thoughts in resolving the same.
Failure happened on 'Source' side. ErrorCode=UserErrorFailToReadFromRestResource,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=An error occurred while sending the request.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.Net.Http.HttpRequestException,Message=An error occurred while sending the request.,Source=mscorlib,''Type=System.Net.WebException,Message=Unable to connect to the remote server,Source=System,''Type=System.Net.Sockets.SocketException,Message=A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ,Source=System,'
This error is mostly seen due to firewall issues. You might want to verify your network firewall setting to allow the API request to be read.
Also, verify if your API call is working as expected using other API testing tools. If the issue persists you can raise a support ticket for engineers to investigate more on the issue.
If you are able to preview data in your source , then check your sink connection as this issue can occur when the Sink in the copy activity is behind a firewall, I was getting the same issue and I tried copying to a container without a firewall and it worked. Its weird that the error is related to Source and the issue is with Sink.

Flow does not run on Tableau Server - where can I see the actual error?

When I run a flow in Tableau Server, it fails with the following error message:
Unfortunately this error is not helpful in understanding the actual cause of the problem.
Is there a way to see the actual underlying error? Or how am I supposed to debug this?
The flow runs fine in my Tableau Prep.
(EDIT: I used state here that I used a different data source to test in prep, but this is no longer true)
Arguably that error log does give you a hint as to what the issue is. The issue is with the Output step. This is most likely due to a permissions error when Tableau Server goes to publish the output since you can do it locally in Tableau Prep.
Are credentials for your flows able to be embedded on server? This will impact whether the output will be accessible. Are all flows run using a service account? Make sure that service account has access to the output location.
If these troubleshooting steps don't work, check the server logs. For this you'll need to check the logs on Tableau Server using the command line to see if there is a more detailed response. If you have the access, run tsm maintenance ziplogs to zip the log files and investigate.

Error connecting Excel to Dashdb

I wanted to connect excel to my bluemix dashdb . I found and followed the directions in the IBM knowldegebase at Article. But am getting the connection error message box when attempting to open the BLUExcel.odc file as recommended in the article. The error I see basically states:
SQL30081N A communication Error has been detected. Communication protocal is tcp/ip. API used is sockets....Protocol specific error code 10061.
Investigation of the specific 10061 error did not resolve the issue.
Interestingly I couldn't connect Excel to any of my dashdb databases so thought I would have a look at the BLUExcel.odc file that gets generated as part of the process.
In there I found the connectionstring had
Hostname = localhost
so I changed this to the hostname that you find in the Connect tab of the dashdb instance you want to connect to and it works fine. Hope this helps someone else..

dashDB Launch Server Error

I have added a dashDB to my app and restaged as required. Unfortunately, when I select the Launch button I get a Server Error 500 page. In the Details I get the following:

It may be down for maintenance or configured incorrectly.
Which I can't decipher.
I read in this forum where one can login using the details from the VCAP_VARIABLES which I was able to do successfully. Interestingly I have annother app on bluemix that also has a dashdb that was accessible but now isn't.
I have dropped the dashDB a couple of times and also created it but left it unbound all for no joy.
Any thoughts will be appreciated.
It looks like a bluemix problem as the dashdb is working fine from the Launch button and I can see the data I loaded when I logged in via the vcap variables.

error opening dashDB

After I have added a service dashDB to my Bluemix application and I click on it, I got in IE11 this message:
The website declined to show this webpage
HTTP 403
When I did the same in the Google crome I got a square head which looked sad.
Does anyone know what to do?
Thank you!
There is not much information to go but I would suggest the following to narrow down the cause of the problem or resolve the issue:
- verify that service has been provisioned successfully (unless it's an existing instance that is known to work in the past)
- clear browser cache/restart to eliminate any transient issues
- BlueMix status page (https://developer.ibm.com/bluemix/support/#status) is currently reporting some authentication issues which potentially could cause problem, it should be check if the 403 error is still reported after the problem is resolved.
It might be worth to create the service with the "leave unbound" option and try to click on it. After you could bind it to your app.
You can verify if the dashDB instance is up or not by accessing the https_url from the VCAP variable associated with the dashDB instance (for e.g.: https://bluemix05.bluforcloud.com:8443) and provide your username and password (also from the VCAP variable) for that instance and see if you can log in.
