Question Reason Sample answer<br />
What are the top three<br />
or four highest yield<br />
workload profile use<br />
cases that cover 80% of<br />
business transactions?<br />
Provides capacity<br />
sizing information<br />
such as activities per<br />
second based on the<br />
underlying workflow<br />
template design.<br />
• 40% of the time – straight<br />
through processing. Case<br />
processor reviews inbox artifacts<br />
and terminates case.<br />
• 20% of the time – straight through<br />
processing with research. Case<br />
processor reviews inbox<br />
artifacts, searches for previously<br />
submitted documents, and<br />
terminates case.<br />
• 10% of the time – expert review.<br />
Case processor reviews inbox<br />
artifacts and routes case to expert<br />
for review and disposition.<br />
Expert uses straight through<br />
processing to terminate case.<br />
• 10% of the time – medical review.<br />
Case processor reviews inbox<br />
artifacts and routes to medical<br />
processor for further review.<br />
Medical reviewer determines<br />
disposition of case and forwards<br />
back to case processor. Case<br />
processor terminates case.<br />
* No database can handle the number of indexes required to search with any combination of the 7<br />
fields under a reasonable volume with reasonable response SLAs. This kind of "search pattern"<br />
classification allows proper database indexing that can scale to billions of records with proper<br />
database sizing, configuration, and maintenance.<br />
Sizing the system<br />
Process-based applications with high volumes of activities have special sizing requirements in a<br />
production environment. Large process volumes can also raise issues of high availability and disaster<br />
recovery, which require more complex and robust hardware requirements.<br />
Use the System Sizing Spreadsheet - <strong>EMC</strong> Documentum 6.5 (available on Powerlink) and BAM<br />
Dashboard Sizing Calculator (available in the BAM Database Sizing Calculator folder of the<br />
bam-product-supplemental_files.zip file) as a starting point to estimate hardware requirements.<br />
Before using either of these sizing tools, identify and model all parameters affecting sizing that are<br />
identified in the capacity planning worksheet (Capacity planning worksheet, page 18).<br />
The <strong>EMC</strong> Documentum System Planning <strong>Guide</strong> provides information on system topologies (distributed<br />
environments, high availability, and so on), which can also affect performance.<br />
