As mentionned in Oracle documention: https://docs.oracle.com/cd/B28359_01/license.111/b28287/editions.htm#DBLIC116,
Asynchronous change data capture is not available in Oracle Standard Edition.
So the question is : is "realtime pipeline" (vs batch pipeline) mode working with Oracle Standard Edition in Google Cloud Data Fusion ?
Cloud Data Fusion currently does not support this capability. However, there are plans to support it, if the oracle instance has GoldenGate or LogMiner enabled.

In order to connect to IBM DB2 from either Excel or a C# .net application, which driver do I need in order to also get the data acceleration? (set current query acceleration all;) Are there drivers that are portable (don't need admin rights to install)?
If they do need admin, I can always ask IT support to install it for me..
Have been using JDBC drivers for my Squirrel SQL client, and they support IBM IDAA (acceleration), but these won't work with Excel nor C#. Obviously.
Any pointers?
To access Db2-for-Z/OS from either Excel or C# .net you will need a CLI driver for Db2 with matching bitness.
Depending on how your Db2-for-Z/OS subsystems are licensed you may also need a license-file on the Microsoft-windows workstation, becase IBM supplied CLI drivers are not free for accessing Db2-fo-Z/OS. Speak with your Z-DBA or passport-advantage-coordinator to get the license-file (and the correct version of it to match your version of Db2-for-Z/OS) or to determine if the target subsystem has already db2connectactivate enabled ( meaning no workstation based licenses are required).
IBM and other companies offer CLI drivers for Db2 for various operating systems including Microsoft Windows.
IBM offers different sizes of CLI driver, depening on how much functionality you need.
Any of these should work with IDAA as long as they are "current", and the keywords needed for IDAA exploitation should be common between the IBM supplied CLI drivers.
The smallest footprint, minimal function, zero install CLI driver from IBM is the "ODBC and CLI" driver, which is a zipfile (just unzip and register it per the docs). Get it via this link, and then install it per this documentation. Note that this driver gets frequently updated, as it is used by all CLI/ODBC based tools (perl, python, r, c#, ruby, c++, ...). It's also possible to use wget to download it. google for that.
A larger driver is the "Db2 runtime client", which has more functionality and the clpplus interface. This is available via the IBM Passport Advantage website , or via fix central for latest fixpacks.
The full Db2 client is a large image, and has all functionality that IBM offers for client side use. Get this via the IBM Passport Advantage website, or via fix central for latest fixpacks.
We are in the process of evaluating redshift for our Cognos Analytics 11.0.11 system. We started seeing weird issues when after publishing a package (CQM mode) so we opened a ticket with IBM and they said Cognos works with redshift only in DQM mode. Is this correct? Have you used Cognos in CQM mode?
Not surprising.
The CQM engine is quite old and connects to datasources through native DB drivers (e.g. if you're connecting to Oracle, you have to install and configure the Oracle client on the Cognos server).
The DQM engine is much newer and uses JDBC drivers exclusively (no requirement to install DB client on the Cognos server).
We are integrating Tableau with MongoDB and wants to decide on cost effective way connecting with MongoDB. We used trial version of Simba and that seem to be costing around $3000/year. Are there other options which are cheaper? We are not on enterprise version of MongoDB so BI Connector is not an option.
Apache Drill has a Mongo Storage Plugin which allows Drill to be used as an 'interrogator' for MongoDB. Drill's ODBC driver can provide BI tools (such as Tableau) with access to MongoDB via Drill.
The setup would be something like:
Install Drill
Add the MongoDB Storage Plugin to your Drill installation
Verify access via the Drill server and using Drill's ODBC driver to MongoDB
Configure Tableau to use Drill's ODBC driver

Tableau Examples
This solution is free (or has no licensing costs, at any rate) but it is somewhat bespoke and cobbled together. My own experience is that ...
Installing Drill is a no brainer
Installing the MongoDB Storage Plugin is a no brainer
Drill's MongoDB Storage Plugin isn't very widely used (or at least it isn't under active development) so you'll likely find the driver works fine but you might find issues with the MongoDB query capabilities providing by Drill's plugin. For example LIKE and IN operators are not supported.
My mongodb is in version 3.0 and run on Linux Redhat 6.
I do not use entreprise options, then I would like to switch enterprise edition to community edition. Any drawback on data? It's much like binary upgrade?
Unless you are using an Enterprise storage engine (eg. Encrypted Storage Engine in MongoDB 3.2+), the data format in MongoDB Community and Enterprise editions is identical and changing between editions is just a change in the MongoDB server binaries. If you need to change storage engines you can do so without downtime on replica sets using a rolling maintenance procedure (see: Your Ultimate Guide to Rolling Upgrades).
I would recommend using matching release versions when changing between MongoDB Enterprise and Community editions to minimize any unexpected issues. The standard upgrade/compatibility caveats (as mentioned in the MongoDB Release Notes) apply if you happen to be upgrading or downgrading between major MongoDB versions (i.e. 3.2 and 3.4).
