Over the coming days, Db2 Warehouse on Cloud Flex plans will be updated with the following changes:
  • A new Db2 engine based on 11.5.4.0. For more information about Db2 11.5.4, see the what's new and the following list of resolved APARs.
  • New features are available through the console interface:
  • The historical monitoring capability gives you the ability to view trends in your database performance, and analyze the database responsiveness, query performance, database throughput, and bottlenecks that are impacting your applications. The historical monitoring settings can be configured to control the volume of monitoring metrics collected and persisted for future analysis. Enable historical monitoring by logging into the console and navigating to Administration > Settings.
  • You can scale the CPU/memory and storage available to your database in an integrated manner from the Db2 Warehouse on Cloud console. The bluadmin user has the privilege to scale by default. In order to enable other users, grant them the INSTANCE_SCALE role.
  • You now have a read-only view of all of the workloads running on your database, and the ability to cancel your own queries and kill your own applications.
  • Support for capturing database events using an external Guardium server. This feature can be requested by opening a support case.

14 Sept 2020

Over the coming days, Db2 Warehouse on Cloud Flex plans will be updated with an updated Db2 engine and an updated console. The base level of the Db2 engine (11.5.2.0) will not be updated, but additional customer fixes will be added on the current level. The console includes the ability to take a backup image on demand and customer fixes. These fixes include the download to CSV file functionality for Edge and Chrome users, and the view of tables and schemas in the storage tab. Supporting software will also be updated.

14 Jan 2020

The Aspera component within Db2 Warehouse on Cloud will be updated and restarted. During this maintenance period, any customers loading data using either Aspera or Lift will experience a short disruption as their connection to the database is reset. The Db2 database instance will not be restarted during this maintenance window, and users connecting directly to the database or using the console will not experience a disruption.

30 Nov 2019

The Db2 Warehouse on Cloud Entry plan will end support on this day.  All instances will be deleted; there will be no option to recover data after this date.  Ensure that you migrate your data out of your Entry plan and into one of the replacement offerings before this date. For more information, see the following blog.

14 Nov 2019

Over the coming days, Db2 Warehouse on Cloud Flex plans will be updated with a new console that includes:
  • Performance improvements
  • Security enhancements
  • Weak password detection. An attempt to update a password will now fail if the new password contains a string that is easy to guess.
  • Fixed term passwords.  An administrator can now set a fixed term password for another user.  When the user logs in with this password, they are prompted to change the password.
  • One additional behavior change. The following parameter must now be supplied when invoking the /auth/token REST API call. Previously this parameter was optional:  -H "Content-Type: application/json" .  The documentation will be updated shortly to reflect this change.
  • Additional fixes
If you load using Aspera from the Db2 Warehouse on Cloud console, it is recommended that you update to the latest IBM Aspera Connect client (version 3.9.6) after this update.  This client is available as a download from the console.  For macOS users only, the current installation must be uninstalled before you install the new 3.9.6 version. .
To uninstall Aspera Connect, quit both the Connect application and any open Web browsers. Then, run the corresponding uninstall script below, based on whether you have a system-wide installation (multi-user) or a per-user installation.
System-wide installation (all users):
$ sudo /Library/Application\ Support/Aspera/Aspera\ Connect/uninstall_connect.sh
Per-user installation:
$ ~/Library/Application\ Support/Aspera/Aspera\ Connect/uninstall_connect.sh

7 Oct 2019

Over the coming days, Db2 Warehouse on Cloud non-Flex plans will be updated with a new Db2 engine, an updated console, and additional fixes. The console now matches the console available on Flex plans.  As part of this update, requirements for passwords have been strengthened.  The minimum password length is now 15 characters (up from 12), and passwords must contain at least one of each of the following types of character: upper case letter, lower case letter, digit, and special character.  When a user's legacy password does not meet the new requirements, the user will be prompted to change their password when they log in to the console.
For a summary of other new and changed features in this console, see the 18 March entry below.

26 August 2019

Over the coming weeks, Db2 Warehouse on Cloud Flex plans will be updated with the following changes:
  • Updated Db2 engine containing Oracle compatibility improvements, BLU compression enhancements, added support for LOB datatypes, concurrency improvements for some types of update and delete statements on column-organized tables, performance improvements for Spatial Analytics, and increased support for external tables.
  • Updated console, with fixes for several defects including an intermittent failure while loading using Lift, and an error that caused file systems to fill up too quickly.  The console also now displays the status during CPU/memory and storage expansion requests.
  • Requirements for passwords have been strengthened.  The minimum password length is now 15 characters (up from 12), and passwords must contain at least one of each of the following types of character: upper case letter, lower case letter, digit, and special character.  When a user's legacy password does not meet the new requirements, the user will be prompted to change their password when they log in to the console.
  • Db2 audit functionality is now available by default on all Flex systems on IBM Cloud.

25 June 2019

A correction was made to the notice below from 21 May. The Db2 audit functionality is now available on all Db2 Warehouse on Cloud non-Flex plans. On Flex plans, the functionality is available by request via a service ticket.  During the next planned update to the Flex plans, the functionality will be made available on these plans.  See the 21 May entry for more information about enabling the feature, which requires configuring an audit policy.

Db2 Warehouse on Cloud (non-Flex plan, non-entry plan) introduces a new console user interface. After your service is updated with the new console, follow the steps here to clear your web browser cache.

The new console includes the following new and changed functionality:

MONITOR

  • On the CONNECTIONS page, you can view applications that connect to the current Db2 Warehouse on Cloud.  When an application might impact the performance of the database, you can use the Force Application button to disconnect the application. You can also filter the applications using different metrics, and export the application status to a spreadsheet file.
  • On the STORAGE page, you can view the storage status in a list or a heat map, either by schema or by table. You can also filter the storage status using different metrics, and export the storage status to a spreadsheet file.
  • On the IN-FLIGHT EXECUTIONS page, you can view the SQL statements that are currently running on the database. You can also filter the SQL statements using different rules, and export the SQL statements to a spreadsheet file.
  • Both administrator and normal users can use the monitoring features. For a normal user, only the data of the current user can be monitored and displayed.


RUN SQL 

  • When you type SQL statements within the SQL editor, the syntax can be validated in real time and recommended fixes for the SQL statement are displayed as annotations in the SQL editor.
  • You can save the SQL statements in the SQL editor either to the server, or to a .sql file in order to share the script with other users.
  • By adding a FAVORITES tag to the saved SQL statements, you can load the SQL statements into the SQL editor with just one click on the drop-down menu of the Favorites button.
  • You can export the result of one or more queries to a spreadsheet file, such as an .xlsx file or a .CSV file.
  • When you access the console from different browsers, the history of SQL statements executed within the SQL editor is also displayed.  
  • You can also choose to run a subset of a group of SQL statements from the SQL editor.
  • The SQL statements that you are working on are automatically saved and will be restored if you lose your connection to the console.


Security Enhancement

  • Forgot password support: For non-entry plans, you can use your user ID and email address to reset the password if you forget your password.  You can also use the /auth/reset REST API to reset the password. The reset instruction is sent to your email address and is valid for 24 hours. Note that you can only reset your password once within 24 hours.
  • Password policy GUI support: Administrators can update or delete the existing password policy, create new password policies, and assign a specific password policy to a user on the Manage Users page, or using REST API endpoints. The principles in a password policy are enforced as follows for different user roles.
Administrator
User
Password expiration date
X
X
Password minimum length
X
X
Failed login attempts
X
X
Account lockout duration
X
X
Password history
X


Support for Internet Explorer

  • You can use Internet Explorer (IE) 11 to access the Db2 Warehouse on Cloud console.


Load

  • You can import data into Db2 Warehouse on Cloud using the load from external tables feature. If the original data is from PureData System for Analytics, it's recommended that you import the data using external tables because the performance is better and there is no lock on an external table.
  • You can load the data from a local .csv file that is larger than 2GB.  However, you need to enable the High-speed loads powered by Aspera button for a file that is larger than 10GB.

7 March 2018

Db2 Warehouse on Cloud (non-Flex plan) now supports IBM Cloud Object Store as a cloud object storage location from which to load data using Db2 utilities and SQL statements (the CREATE EXTERNAL TABLE statement) directly. Both regional and cross regional endpoints are supported. The same support is already included in the initial release of the Db2 Warehouse on Cloud Flex Performance plan.


20 February 2018

See the following announcement relating to Db2 Warehouse on Cloud:
https://www.ibm.com/blogs/bluemix/2018/02/upcoming-changes-rstudio-db2-warehouse-cloud/
