reintializes all connections established in the specified connection pool


flush-connection-pool [--help] pool_name 
[--appname application [--modulename module]


The flush-connection-pool subcommand resets a JDBC connection pool or a connector connection pool to its initial state. Any existing live connections are destroyed, which means that the transactions associated with these connections are lost. The subcommand then recreates the initial connections for the pool, and restores the pool to its steady pool size.

This subcommand is supported in remote mode only.

Application Scoped Resources

The flush-connection-pool subcommand can target resources that are scoped to a specific application or module, as defined in the glassfish-resources.xml for the GlassFish domain.

  • To reference the jndi-name for an application scoped resource, perform the lookup using the java:app prefix.

  • To reference the jndi-name for a module scoped resource, perform the lookup using the java:module prefix.

The jndi-name for application-scoped-resources or module-scoped-resources are specified using the format java:app/jdbc/myDataSource or java:module/jdbc/myModuleLevelDataSource. This naming scope is defined in the Java EE 6 Specification (https://download.oracle.com/javaee/6/api/).



Displays the help text for the subcommand.


Name of the application in which the application scoped resource is defined.


Name of the module in which the module scoped resource is defined.



Name of the connection pool to be reinitialized.
