Concepts
Optimize has six components or activities that access the Optimize database component sets:

analysis.engine Analytic Engine

process.history Analytic Engine

process.model Analytic Engine

process.work Analytic Engine

common.directory Analytic Engine
A typical Optimize configuration of database connection pools involves four connections:

analysis.engine Analytic Engine through a pool to the Analysis database component set

process.history Analytic Engine and process.work Analytic Engine through a single pool to the Process Tracker database component set

process.model Analytic Engine through a pool to the Process Audit Log database component set

common.directory Analytic Engine through a pool to the
My webMethods Server database component set
See the following figure.
Connecting Optimize database activities to Optimize database component sets: typical configuration
In high-volume situations, you may be able to improve performance by assigning separate database connection pools to:

The process.history Analytic Engine and process.work Analytic Engine
Optimize database activities; both connect to the Process Tracker database component set.

The analysis.engine Analytic Engine
Optimize database activities; connects to the Analysis database component set.
See the following figure.
Connecting Optimize database activities to Optimize database component sets: high-volume configuration
Note:
You must define a minimum of one database connection pool per database schema. In an Optimize configuration with four database schemas as shown in the figures above, you must define a minimum of four database connection pools.
