Major Enhancements to Oracle 10g Analytic Workspace Manager Announced
August 31, 2004
Mark Rittman

Oracle's Data Warehouse Guru, Anthony Waite just published this announcement on OTN:

The patchset for Oracle 10g is now available on MOSC, patch number 3761843. It's a 448MB download and is available now for MS Windows, Intel Linux, and a few of the 64-bit Unices. There are two corresponding OLAP patches; OLAP patch (patch number 3769360) which Oracle
recommend should be applied to all existing installations - both client and server - and a patch, due out at the end of September, along with version two of the Analytic Workspace Manager.

The patch introduces a couple of items of new functionality to Oracle OLAP:

a.. The existing AWM is upgraded to AWM, with  users no longer being required to     manually enable the analytic workspace for query by the OLAP API. Dynamic enablement automatically     creates compatible SQL views over the analytic workspace even if you change the logical model.

b. AWM uses the new AWXML feature for query access, with the forthcoming AWM2     switching over completely to AWXML for defining and loading AW objects.

Although the patch looks interesting, the major change for 10g OLAP is coming with the patch, which introduces all the features outlined in Mike Ault's 10g OLAP article and Anthony Waites comments earlier in the year on the OTN OLAP Forum. Oracle OLAP, through it's use
of AWXML and AWM2, will allow analytic workspaces to be created directly from Oracle relational tables, or flat files using the external tables feature, without the intermediate step of creating a CWM1-compliant ROLAP cube. In addition, AWM2 will support new features that have been introduced with 10g OLAP, including multi-writer support, partitioning and compression, and will have a big emphasis on users who are 'data dabblers', making it easier to create and populate analytic workspaces.

The patch, and AWM2, are scheduled to be made available around 30th September.

As all of this will make the current 10g OLAP documentation out of date, the OLAP DML Guide is being be re-edited and should be available within a week.
