Data Integration Service

Effective in version 9.6.0, when you run Data Integration Service jobs in separate operating system processes, the Data Integration Service maintains a pool of reusable DTM processes. Each job runs in a DTM process selected from the pool. One DTM process can run multiple DTM instances for related jobs. If you configure connection pooling, each DTM process maintains its own connection pool library that it can reuse for related jobs that run in the same DTM process.

Previously when you ran Data Integration Service jobs in separate operating system processes, each job ran in a separate DTM process. One DTM process ran a single DTM instance. When you ran jobs in separate operating system processes, the Data Integration Service ignored the connection pooling properties.
