Designing HFM’s 12 Dimensions

Application Profile1. Year2. Period3. View

System4. Value dimension,

includes currencies

User controlled5. Entity6. Account7. ICP8. Scenario

User defined9. Custom 110. Custom 211. Custom 312. Custom 4

Application Profile

YearNo inherent impact on performanceCannot be changed after the application is builtImpacts the number of tables that can be

created in the databasePeriod

The base periods comprise the column structure of every table, whether you use them or not.

For this reason, avoid weekly or yearly profiles unless it is key to your entire application’s design

ViewNo impact, but only YTD is stored and Periodic,

QTD are on-the-fly derivations

What’s a Subcube?

Data Design

DensityContent

Specifically: zerosTiny numbersInvalid Records

Loaded Data

What percent of the loaded data is a zero value?No hard rule, but <5% may be reasonableNo zeros are best, watch ZeroView settings on the

scenariosWatch out for tiny values, resulting from allocationsHow much does the data expand from Sub Calculate?

Am I generating zeros, or tiny numbers?

HFM 11.1.1: the magic of 64 bit!

Measure and Analyze RulesHow much time

do I spend in each rule?

Let’s focus on the “top

10”

Rewrite the rule for optimal

performance

Do some months take longer than

others?

Is it because they have

more data?

Establish a Baseline

Effect of cachingData cache on database server AND on HFM application

serverCaches may be empty during first runPerformance is significantly better when data reads comes

from memory cache rather than disk This is why cache management is so important

Run the same process 3 times in a row and use the average

“Performance begins with perception. Establish this and a baseline before applying science.”

“Rules” of Thumb

Most application between 0.25 and 2.0 seconds per 0.25 and 2.0 seconds per entity, per periodentity, per periodConsolidate all with data for entire hierarchy, full yearDivide by total number of entities (descendents of

selected parent), divided by 12 periodsMost applications are closer to 0.25 seconds

Rules Impact RatioBlank rules file, Consolidation Rules = N for baselineDivide consolidation time with rules by time withoutUsually 2-5 times2-5 times

The Black Art of Reading HFM Event Logs

Where does HFM store its event information?

Maintaining the logsHow can I view this?OK, what does it actually tell me?

Understanding HFM Logs

Messages Messages are informational –start/stop consol, log in, log

out etc. Some messages are purposely out of time order (consol

starts get printed at completion of consol

Warnings Often due to subcube size issues HFM Subcube Troubleshooting Guide / Memory

Management in HFM documents

Errors Access rights Syntax Issues

Where are the HFM events stored?

Text file containing XML, named HsvEventLog.log

Pre-HFM 9.2.0.2 or 9.3.0 ..\Hyperion Solutions\Hyperion Financial Management\Server Working Folder\

Starting with 9.3.1 Oracle moved all product logs to a common parent folder HYPERION_HOME\Logs\FinancialManagement or HYPERION_HOME\Logs\HFM

How can I view this?

Administration Module Web: Administrators only

HFM Error Log Viewer utility Free standing executable Bundled with HFM under \Consultant

Utilities

Web System Messages

Available to administrators

Launch the Utility

Launch HFMErrorLogViewer.exe

System Message panel

Details panel

Details

Web suppresses richer details shown in utility

Find “Registry”

Each server’s registry settings are written during an application start-up.

Most but not all registry entries are writtenWe’ll cover the actual entries in another

presentation

System Memory at Inception

Page File Size Increased in 9.2.0.3, 9.3.1 to 130 and 260 MBStill exists in 64 bit HFM 11.1.1, but likely unused

Paging

Watch “PageOutOps > 0” indicating page file usage

Consolidation start and finish

Summary indicates start time

Details have finish time

Is written when it completes

Extracting Log Entries

HFM writes to both the event log and the database

You can extract the database entries to a text file, which is preferable to the event logs

Can also truncate the entries using this utility

And split large files (anything > 30 MB is too large)
