This added the route, however, I am still not able to ping to 10.67.26.89.
The route command says the following: if you got a packet for 10.67.26.89, then send it to 10.61.1.1 and the host owning this interface will know how to deal with it. Do you even get to 10.61.1.1? If not, this is the problem! (Tip: if you use ping to test specific connections you assume that the ICMP protocol - which is used by ping - is allowed. This is usually not the case in firewalled environments. They usually drop ICMP packets silently.

Use this:
Code:
telnet <targethost> <targetport#>

for tests then. You won't get a telnet connection at all, but you will find out if you get even there (connection attempts fails, usually with some banner from the application waiting behind the port) or not (connection times out with "host unreachable" or so).

In general systems should not know how to route (quite like routers should not do other work besides routing). This is why you should not explain to the routing table of your system about how to use the foreign address 10.61.1.1 to get to some remote server because you need to tell it how to get to 10.61.1.1 itself first. Let the routers decide this and tell the system which interface to use to send the packet:

Code:
# route add net 10.67.26.89 netmask 255.255.255.255 <your interfaces IP> 1

and the router adjacent to this interface should be able to forward it on its own. Otherwise your network design is flawed.

I hope this helps.

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

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