Repository Performance Properties for the Model Repository Service Process

Repository Performance Properties for the Model Repository Service Process

Performance tuning properties for storage of data objects in the Model Repository Service.
The Model Repository Service uses an open source object-relational mapping tool called Hibernate to map and store data objects and metadata to the Model repository database. For each service process, you can set Hibernate options to configure connection and statement pooling for the Model repository.
The following table describes the performance properties for the Model Repository Service process:
Property
Description
Hibernate Connection Pool Size
The maximum number of pooled connections in the Hibernate internal connection pooling. Equivalent to the hibernate.connection.pool_size property. Default is 10.
Hibernate c3p0 Minimum Size
Minimum number of connections a pool will maintain at any given time. Equivalent to the c3p0 minPoolSize property. Default is 1.
Hibernate c3p0 Maximum Statements
Size of the c3p0 global cache for prepared statements. This property controls the total number of statements cached. Equivalent to the c3p0 maxStatements property. Default is 1000.
The Model Repository Service uses the value of this property to set the c3p0 maxStatementsPerConnection property based on the number of connections set in the Hibernate Connection Pool Size property.
