To Contact (Ping) a Connection Pool

Use the ping-connection-pool subcommand in remote mode to test if a connection pool is usable. For example, if you create a new JDBC connection pool for an application that is expected to be deployed later, you can test the JDBC pool with this subcommand before the application is deployed. Running a ping will force the creation of the pool if it hasn't already been created.

Before You Begin

Before you can contact a connection pool, the connection pool must be created with authentication, and the server or database must be running.

1. Ensure that the server is running.

   Remote subcommands require a running server.

2. Ping a connection pool by using the ping-connection-pool(1) subcommand.
