Flush-Connection-Pool
Reintializes all connections established in the specified connection pool.
Synopsis
asadmin [asadmin-options] flush-connection-pool [--help]
[--appname application [--modulename module]
pool_name
Description
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 or payara-resources.xml for the Payara Server domain.
|
Important
|
glassfish-resources.xml is deprecated and support will be removed in a future release. It is recommended to use payara-resources.xml instead. |
