Are you ready for a Demantra Worksheet Webcast?

The Key to Optimizing Demantra Worksheet Performance will be presented September 11, 2013 at 10am Central.
Please see Demantra Solutions Advisor Webcast Calendar And Archive (Doc ID 800030.1) in My Oracle Support.

Worksheet Performance Problems? Try this action plan

The index advisor can be ran for a user, all users, a worksheet, all worksheets or the entire schema. I am suggesting we run it for the two slowest worksheets and implment the results.
1) Are the workstations configured to use the maximum amount of Java memory?
2) Are you using client expressions?  
3) Are you using server expressions?  Can any of the data be adjusted and saved prior to worksheet open?
4) Have you iosolated the SQL that drives the slowest responding worksheets for tuning/index improvements?
5) Have you submitted the longest running SQL to Support for suggestions?
6) Has that longest running SQL been executed outside of the worksheet display process to determine if the expected results are realistic considering available hardware and matematical physical limits of hardware?
7) Have you analyzed your approach to retrieving/adjusting forecast data? The past approach may not be the best. For example, aggregation levels, forecast horizon, the amount of families or business lines retrieved at once for any particular worksheet.
8) Is your instance undersized before adding any new sales_data data. A complete review of
production and supporting instances, such as test, could be conducted.  Use note 1301231.1.
9) What is your forecast horizon?  Is this required for every worksheet even during the planners day-to-day tasks of forecast adjustment? Can you use a 'master plan' worksheet approach.
10) A complete review of all Demantra param and environment variable needs to be conducted. These should match the capabilites of the RDBMS and the application server.
11) A complete review of the application server settings needs to be conducted to allow for maximum performance.
