UniversalConnectionPoolStatistics (Oracle Universal Connection Pool Java API Reference)

All Known Subinterfaces:

JDBCConnectionPoolStatistics, OracleJDBCConnectionPoolStatistics
```
public interface UniversalConnectionPoolStatistics
```
Various runtime statistics for the Universal Connection Pool. This interface provides query-only operations on all available pool statistics.
The cumulative statistics are collected across multiple pool start/stop cycles, while the others only apply to the current running connection pool instance.
