I'm trying to connect a database in the Bluemix DB2 on Cloud (DashDB) to IBM BPM on Cloud. Is this possible? I tried setting up a datasource in BPMoC using the data provided by DB2 on Cloud, but it is not able to connect:
(Error Details)[jcc][t4][2043][11550][4.18.60] Exception
java.net.SocketException: Error opening socket to server ... with
message: Network is unreachable (connect failed). ERRORCODE=-4499,
SQLSTATE=08001 DSRA0010E: SQL State = 08001, Error Code = -4,499Test
Connection
IBM BPM on Cloud support was able to help me get this working. There was something that needed to be done on the network side of things to allow BPMoC to talk with DB2 on Cloud (Bluemix). They also had to install the SSL certs for me.

I am unable to connect to a Mongo db which is hosted in IBM cloud. I have got the credentials and the db name. I am using direct authentication method but getting sometime timeout error or sometime "Client network socket disconnected before secure TLS connection was established" error. I am new to Mongo client. It seems ibm cloud team do not set any restrictions and on public internet. I can do a telnet with the server string.
1.Do I need to use any configuration in Mongo compass client like installing certificates?
2.Do I need to request for ip binding (though my ip is dynamic)
Any help will be appreciated on this
I am trying to test a connection using Cloud Data Fusion to connect to an on-prem SQL Server. Our GCP Project does not use the default network but rather a custom VPC.
It's important to note that security is very important as this database contains healthcare data.
We currently have App Engine Flex code that uses pymssql to query the database on this SQL Server through the VPC, and want to test using Data Fusion.
I have copied and added the generated data fusion service account to IAM with role Cloud Data Fusion API Service Agent.
I have configured in Data Fusion
system.profile.properties.network = <VPC name>
I have verified that the username and password for authentication to SQL Server are valid for the database.
THE VPC network allows port 22 and 1433.
At this point I am just trying to get a successful connection to query a table in the database.
Here is the error message I get:
Connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.
Thoughts?
It looks like you can access SQL Server from GCP (via AppEngine Flex Py code) but having trouble connecting through Data Fusion. It also looks like authentication doesnt seem to be a problem (as the error message is around connection).
One area I can think of is to try Cloud Data Fusion private IP, that allows you to securely connect to your VPC from Cloud Data Fusion. This is a new feature and you will need Data Fusion product team support to leverage this feature.
I failed to connect to MySQL from google data fusion
the step:
First, I add the connector
https://dev.mysql.com/downloads/file/?id=462850
Second, I try to add a connection (failed)
screenshot of the MySQL:
Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
**** Edit **** I think this is associated with allowing data fusion to access to our production data
my second question is:
How can I know what is the Google Data Fusion IP address?
if someone can help me that will be wonderful
thank you
This error indicates that Cloud Data Fusion is unable to connect to mysql via JDBC with the given credentials (Host/port/User). You will need to ensure that the user provided can connect from any host. To trouble shoot this further, please do the following:
SSH to the mysql box and run netstat -tln and confirm if the port where mysql is running on is 3306
Login to mysql using Mysql CLI or a workbench tool and run the following
SHOW DATABASES to list all the Databases in mysql and see if the one you are accessing is present
Ensure that the user that is accessing mysql from Data Fusion can access from any hosts by running SHOW GRANTS FOR 'username'#'%'
Here are some additional articles that might help with troubleshooting. https://serverfault.com/questions/89955/unable-to-connect-to-mysql-through-jdbc-connector-through-tomcat-or-externally
Even if you try to access via public IP it'll not work. I had the same issue. Because you have to enable VPC peering between the Datafusion tenant project id with your VPC.
Detailed steps are here: https://cloud.google.com/data-fusion/docs/how-to/create-private-ip
I have configured Bluemix Secure gateway client to connect to DB2 on AS 400 using a Windows machine. I am able to run the Db2 connection successfully from the application on Windows machine where Secure gateway client is running. But when I run the same application on Bluemix with modifying the code to depict Secure Gateway client destination details, I get 'Connection Refused' error.
I had gone through how to connect a bluemix app to on-premise db/as400? , which mentions about Secure gateway client for OS 400.
Wanted to understand how to fix the issue for 'Connection Refused' ? Do we have to use different DB2Driver/ DB2 Connect string from Bluemix? or Any other settings to be done on AS400 server?
Given that the Connection refused error is occurring between your BlueMix application and the SG Servers and no logs are being generated on the SG Client, it sounds like the issue is with a listener not being opened on the SG Servers rather than an issue between the SG Client and DB2. All listeners should come up when the SG Client initially connects to the SG Servers.
Are you able to cURL or telnet the cloud host:port provided with this particular destination? Or is this connection refusal specific to your BlueMix app? In either case, this answer will provide more direction on where to investigate further.

I am getting this error when trying to create a Bluemix server in Eclipse, specifically on click of Validate Account button. I have downloaded and installed the IBM Bluemix for Eclipse plug-in but still having connectivity issues. Any help is appreciated.
The connection error is depending from the wrong IP address your internet ISP/provider is returning for api.ng.bluemix.net
Check your DNS configuration, you could run the following command
nslookup api.ng.bluemix.net
to check which DNS server is returning the wrong IP address.
