may be this is the problem -


from man page of ping -

argument of inet, IPv4 is used. For inet6, IPv6 is used.

By default, if the name of a host is provided,not the literal IP address, and a valid IPv6 address exists in the name service database, ping will use this address. Otherwise, if the name service database contains an IPv4 address, it will try the IPv4 address.

Specify the address family inet or inet6 to override the default behavior. If the argument specified is inet, ping will use the IPv4 address associated with the host name. If none exists, ping will state that the host is unknown and exit. It does not try to determine if an IPv6 address exists in the name service database.

If the specified argument is inet6, ping uses the IPv6 address that is associated with the host name. If none exists, ping states that the host is unknown and exits.

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

       asadmin-create-connector-connection-pool(1AS),  asadmin-delete-connector-connection-pool(1AS), asadmin-list-connector-connection-pool(1AS),
