Example of a Connection Pool

Example of a Connection Pool

You want to use connection pools to optimize connection performance. You have configured the Data Integration Service to run jobs in separate local processes.
You configure the following pooling properties for a connection:
  • Connection Pooling: Enabled
  • Minimum Connections: 2
  • Maximum Connections: 4
  • Maximum Idle Time: 120 seconds
When a DTM process runs five jobs, it uses the following process to maintain the connection pool:
  1. The DTM process receives a request to process five jobs at 11:00 a.m., and it creates five connection instances.
  2. The DTM process completes processing at 11:30 a.m., and it releases four connections to the connection pool as idle connections.
  3. It drops one connection because it exceeds the connection pool size.
  4. At 11:32 a.m., the maximum idle time is met for the idle connections, and the DTM process drops two idle connections.
  5. The DTM process maintains two idle connections because the minimum connection pool size is two.
