Removing section from tnsnames.ora

Hi,
I am trying to write a script or command to remove a section from tnsnames.ora file

in the following example I would like to remove tns_alias2 section

Code:

$ cat tnsnames.ora
tns_alias1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host1 )(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = service1)
    )
  )

tns_alias2 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host2 )(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = service2)
    )
  )

tns_alias3 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host3 )(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = service3)
    )
  )

$ sed ......

$ cat tnsnames.ora
tns_alias1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host1 )(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = service1)
    )
  )

tns_alias3 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host3 )(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = service3)
    )
  )

net::time

Net::Time(3pm)						 Perl Programmers Reference Guide					    Net::Time(3pm)

NAME

       Net::Time - time and daytime network client interface

SYNOPSIS

	   use Net::Time qw(inet_time inet_daytime);

	   print inet_time();	       # use default host from Net::Config
	   print inet_time('localhost');
	   print inet_time('localhost', 'tcp');

	   print inet_daytime();       # use default host from Net::Config
	   print inet_daytime('localhost');
	   print inet_daytime('localhost', 'tcp');

DESCRIPTION

       "Net::Time" provides subroutines that obtain the time on a remote machine.

       inet_time ( [HOST [, PROTOCOL [, TIMEOUT]]])
	   Obtain the time on "HOST", or some default host if "HOST" is not given or not defined, using the protocol as defined in RFC868. The
	   optional argument "PROTOCOL" should define the protocol to use, either "tcp" or "udp". The result will be a time value in the same
	   units as returned by time() or undef upon failure.

       inet_daytime ( [HOST [, PROTOCOL [, TIMEOUT]]])
	   Obtain the time on "HOST", or some default host if "HOST" is not given or not defined, using the protocol as defined in RFC867. The
	   optional argument "PROTOCOL" should define the protocol to use, either "tcp" or "udp". The result will be an ASCII string or undef upon
	   failure.
