Zero means idle connections never expire. Number of seconds that Connections in excess of c3po jdbc should be permitted to remain idle in the pool before being culled.
Intended for applications c3po jdbc wish to aggressively minimize the number of open Connections, shrinking the pool back towards minPoolSize if, following a spike, the load level diminishes and Connections acquired are no longer needed. Zero means no enforcement, excess Connections are not idled out.
Maximum number of Connections a pool will maintain at any given time. The size of c3po jdbc global PreparedStatement cache. If both maxStatements and maxStatementsPerConnection are zero, statement caching will not be enabled.
C3p0-v - JDBC3 Connection and Statement Pooling - Documentation
If maxStatements is zero but maxStatementsPerConnection is a non-zero value, statement caching will be enabled, but no global limit will be enforced, only the per-connection maximum. C3po jdbc set, it should be a fairly large number, as each pooled Connection requires its own, distinct flock of cached statements. As a guide, consider how many distinct PreparedStatements are used frequently in your application, and multiply that number by maxPoolSize to arrive at an appropriate value. Though maxStatements is the JDBC standard parameter for controlling statement caching, users may find c3p0's alternative maxStatementsPerConnection more intuitive to use.
The number of PreparedStatements c3p0 will cache for a single pooled Connection. If maxStatementsPerConnection is zero but maxStatements is a non-zero value, statement caching will be enabled, and a global limit enforced, but otherwise no limit will be set on the number of cached statements for a single Connection.
If set, maxStatementsPerConnection should be set to about the number distinct PreparedStatements that are used frequently in your application, plus two or three extra so infrequently statements don't force the more common cached statements to be culled. Though maxStatements is the JDBC standard parameter for controlling statement caching, users may find maxStatementsPerConnection more intuitive to use. Minimum number of Connections a pool will maintain at any c3po jdbc time. Slow JDBC operations are generally performed by helper threads that don't hold contended locks.

Spreading these operations over multiple threads can significantly improve performance by allowing multiple operations to be performed simultaneously. Forces the username that should by PooledDataSources when a user calls the default getConnection method. This is primarily useful when applications are pooling Connections from a non-c3p0 unpooled DataSource. Applications that c3po jdbc ComboPooledDataSource c3po jdbc, or that wrap any c3p0-implemented unpooled DataSource can use the simple user property. Forces the password that should by PooledDataSources when a user calls the default getConnection method.
Applications that use ComboPooledDataSourceor that wrap any c3p0-implemented unpooled DataSource can use the simple password property. See also user.From a users' perspective, c3p0 simply provides standard jdbc DataSource objects.

When creating these DataSources, c3po jdbc can control pooling-related. a mature, highly concurrent JDBC Connection pooling library, with support for caching and reuse of PreparedStatements.
