Code:
       $|      If set to nonzero, forces a flush right away and after every
               write or print on the currently selected output channel.
               Default is 0 (regardless of whether the channel is really
               buffered by the system or not; $| tells you only whether you've
               asked Perl explicitly to flush after each write).  STDOUT will
               typically be line buffered if output is to the terminal and
               block buffered otherwise.  Setting this variable is useful pri-
               marily when you are outputting to a pipe or socket, such as
               when you are running a Perl program under rsh and want to see
               the output as it's happening.  This has no effect on input
               buffering.  See "getc" in perlfunc for that.  (Mnemonic: when
               you want your pipes to be piping hot.)

asadmin-ping-connection-pool

asadmin-ping-connection-pool(1AS)				   User Commands				 asadmin-ping-connection-pool(1AS)

NAME

       asadmin-ping-connection-pool, ping-connection-pool - tests that a connection pool is usable

SYNOPSIS

       ping-connection-pool --user admin_user [--password admin_password] [--host localhost] [--port 4848] [--secure|-s] [--passwordfile filename]
       [--terse=false] [--echo=false] [--interactive=true] pool_name

       Tests that a connection pool is usable for both JDBC connection pools and connector connection pools. For example, if you create a new JDBC
       connection  pool for use with an application that is expected to be deployed, before deploying the application, the previously created pool
       is tested with this command.

       This command is supported in remote mode only.

OPTIONS

       --user		       authorized domain application server administrative username.

       --password	       password to administer the domain application server.

       --host		       machine name where the domain application server is running.

       --port		       port number of the domain application server listening for administration requests.

       --secure 	       if true, uses SSL/TLS to communicate with the domain application server.

       --passwordfile	       file containing the domain application server password.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
			       formatted data for consumption by a script. Default is false.

       --echo		       setting to true will echo the command line statement on the standard output. Default is false.

       --interactive	       if set to true (default), only the required password options are prompted.

OPERANDS

       poolname 	       name of the connection pool to be tested.

       Example 1: Using ping-connection-pool

       Before you can ping a connection pool, you must:

	 o  Create a connection pool with authentication.

	 o  Make sure the Enterprise Information Server (can be the database) is started.

       asadmin> ping-connection-pool --user admin1 --password adminadmin1
       --host pigeon --port 5001 sampleConnectionPool
       Command ping-connection-pool executed successfully

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
