I am trying to setup a change data capture system using Debezium on DB2 on cloud database. Since Db2 on cloud is a saas offering I am not able to access a linux server where db2 is installed. And the Debezium connector requires me to set up a ASN CDC agent on the linux server by running commands in the linux terminal of the server hosting the db2. Is there any work around for this? or any other open source solutions for change data capture that I can use here.

I have a Azure database for PostgreSQL and want to set up my Azure Analysis Service with this Postgres on Azure as datasource.
I'm not sure whether PostgreSQL on Azure is supported by AAS? I am getting the below error when trying to connect:
Error
I tried with the below extension, but installing it did not resolve the issue:
Npgsql installed
My assumption is that I need to install the on-premise gateway to be able to connect this Azure PostgreSQL db - can anybody confirm this is the right direction and will resolve the connection issue?

According to KranthiPakala:
Azure Database for PostgreSQL is not a supported data source of AAS.
You can connect to on-prem PostgreSQL as a data source for import or in-memory tabular models. In order to do this, select the ODBC data source option(start a new import connection , choose ODBC option, then pick the ODBC source name) and AAS will treat it like SQL Server.

I have this mongoDB (a SaSS in IBM Cloud) and on this cloud i also have an instance of another noSQL DB, cloudant db.
We were able to connect the cloudant DB on Power BI using only an URL such as "https://8869f932-05f0-4f48-b697-XXXXXXXXXXXX-bluemix.cloudantnosqldb.appdomain.cloud/<DATABASE_NAME>/_design/<DESIGN_DOC_NAME>/_view/<VIEW_NAME>" and "WEB" connection option on PowerBI.
My question is, and i didn't find any info or documentation related to this matter: on MongoDB, there is a way to achieve this kind of connection, using only a uri to a specific view rather than the ODBC connection?
If not, is there any other alternative to connect with this resource on IBM instead of ODBC?
Install mongosqld from : https://docs.mongodb.com/bi-connector/current/installation/
Run mongosqld
Now you can connect to the mongodb instance with read access using mysql/mariadb client or drivers.
NOTE: As mentioned this only has read access, so you can execute all the select queries.
I don't think so if PowerBI doesn't support it already. The MongoDB BI Connector isn't installed in IBM Cloud Databases for MongoDB.
I´d like to know if it is possible to connect to my rds database from my local machine (windows) using windows odbc data source. My problem is that I use SSH and i don´t know how can I input the parameters in odbc data source. I need this type of connection because I want to access RDS via vba excel. My database is Postgresql.
If you have a publicly accessible database (not recommended by AWS) and your IP address is allowed, then the normal ODBC connection will work.
By the sound of your setup, you have a private database. In which case, your options are:
Use a different ODBC driver that supports tunnelling.
Devart (https://www.devart.com/odbc/postgresql/) and Cdata (https://cdn.cdata.com/help/FPG/odbc/RSBPostgresql_c_SSH.htm) both have ODBC drivers that support SSH tunnelling.
Neither are free.
Use a VPN and point your driver at localhost
I tried taking backup of dashdb from bluemix cloud using Data Studio. I am getting this error 'Remote target is unreachable.'.
Since this is an admin activity, I assume it should be done on the server. As this is cloud server, I am trying to understand how this can be done!
Are there any tools which support ssh to the server and how to take backup of the db? Any documentation in this regard?
Thanks
Which plan are you using ?
Have you read the details of backup on the FAQ ?
This section might help:
Is my data backed up? Encrypted backups on the full Db2 managed service database are done daily. For the Db2 Warehouse on Cloud Flex Performance plan, the
last 7 daily backups are retained. For all other Db2 Warehouse on
Cloud plans, the last 2 daily backups are retained. For Db2 on Cloud,
the last 14 daily backups are retained. In the Db2 Warehouse on Cloud Flex Performance plan, you can restore your database from any of your retained backups at any time
that you choose. In the case of all of the other Db2 Warehouse on
Cloud plans, the retained backups are used exclusively by IBM for only
system recovery purposes in the event of a disaster or system loss. A
request to restore your database from a backup is not supported. You
can export your data using Db2 tools such as IBM Data Studio or by
using the db2 export command.>
For Db2 on Cloud, backups can be stored off site in a different data center or region upon request to IBM Support. These backups are
also used exclusively by IBM to recover from only disaster or system
loss events. A request to restore your database from a backup is not
supported.
Are there any tools which support ssh to the server and how to take backup of the db? Any documentation in this regard?
SSH is not supported as this is a managed service. This is documented in the FAQ:
How do I access the Db2 managed service database?
You can access your Db2 managed service database through the web console from a browser, or you can connect to the database with a client connection such as JDBC, ODBC, CLI, CLP, or CLPPlus. A direct login to the server with Telnet or a Secure Shell (ssh) is not supported.
If you want to take your own backups at the interval of your choice, exporting your data is your best option. That can be done from the web console or from a database client.
Alternatively, if what you're after is access to historical data, you can use time travel query.
I have downloaded Tabeleau 8.0.1 desktop version. I am able to connect my local postgres database through tableau.
But when I try to connect to the redshift cluster, I am getting an error - invlaid userid /password. I already have passed userid and password correctly. FYI, I am able to connect redshift through sqlworkbench/j, command line prompt (psql) & pgadmin III. And I already have downlaoded the redshift driver as per http://www.tableausoftware.com/support/drivers.
However I am not able to connect redshift cluster through tableau.
Amazon Redshift has a direct connect with Tableau. When you start Tableau, please use the Connect to Data option and then choose Amazon Redshift on the left. You'll see the following log-in screen. You shouldn't need to worry about drivers. Also, the Tableau trial version is the full version, so there is no limiting of features.
You can read more here, and watch a video. Also technical details are here. You may want to try version 8.1, which is the most recent version (also has 64 bit)
