TDS Experience at Emfisys
Configuration
All data from single TMR Soon to collect from three more Many gateways
Single TDS server handles all functions TDS application, Cognos cubes, also
Oracle databases (SPP, maybe others) SPP database on TDS servers
Gives TDS users access to raw data Inventory database helps billing & costing

Successes
Collecting performance data from 100+ production servers Producing daily reports for 40+ business
applications on BMO intranetBenefit to application support teams
Using database with other business information to produce capacity updates
Planning to expand to 1,500+ serversMore efficient capital & expense dollars

TDS Experience at Emfisys
Challenges (1 of 4)
Job timeout applies to response only All Tivoli, not just TDS
e.g. aggregation and database population jobs
Timed-out job task continues to run
Need longer baseline for extrapolating trends 6 months may exclude seasonal peaks
e.g. Christmas, RRSP seasonEnhancement requested Oct/2000, available?

TDS Experience at Emfisys
Challenges (2 of 4)
Need workload characterizationServers will soon run multiple applications
Need differentiation between actual and forecast data
e.g. on Hourly views, can’t tell which is whichRequirement not yet raised to Tivoli
Need System Purpose matrixReplace single unsorted text-only variable in
Cube 3 with a matrix with sorting, etc.Enhancement requested Oct/2000

Challenges (3 of 4)
Database maintenance and product recovery functions should be delivered
Oracle database cleansing, re-org, tuning, etc.Aggregation file backupDM event(s) for RIM failure, data collection
failureControl over data collection retriesPopulation job log file cleansing or rollover
New version difficultiesImplementation of DM 4.0 has yielded 42
layers instead of 18…?

TDS Experience at Emfisys
Challenges (4 of 4)Graphics flexibility
Changes sometimes not accepted in TDSUsing Cognos as delivered with TDS helps but
design capability still limited• Exploring full-function version of Cognos, but need to
know if “new TDS” will use it
Want to include capacity threshholds on charts
Web outputJPG output files too big, GIF smallerEnhancement requested Oct/2000Automated thumbnails would be nice

TDS Experience at Emfisys
Opportunities
Expansion planned to over 1,500 servers Capacity planning and performance
reporting handled by three-person team Enabled by top-down ability to focus on
servers trending towards trouble or running off trend
Looking to evaluate TDS Oracle, UDB, Notes and TSM Discovery Guides
Apr. 24, 2002 For CMG Canada - J.Gladstone, Bank of Montreal

TDS Experience at Emfisys
Conclusions
TDS has potential to allow a small team to handle capacity planning for a very large number of servers
Require Tivoli support Database tuning Product enhancements
Server purpose matrixGraphics flexibilityetc.
