How to force UC4 Database Agent to use a connection to a remote database only once
The configuration of the connection pool in SQL Agents can be done with the retention_time parameter in the INI file.
In V9 the connection pool can be turned off with the parameter retention_time=0.
In V8 the value retention_time=0 will reuse a database connection if Jobs are running in the same second against the same database.
