Hello Sonia,

you should try add the following information for both server (ITSM764_125,
ITSM764_126) in the transname.ora file
ITSM764_125 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ARS7604)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = ITSM764_125)
      (SERVER = DEDICATED)
    )

and then you have to put individual information for server in ar.conf file
as

Server-Name: <Your_Server_Name>
Oracle-Two-Task: ITSM764_125

for both the machine your are trying to connect as in your case like
(ITSM764_125, ITSM764_126), then restart your server.
Before doing there activity take necessary back up of bothe transname.ora
and ar.conf file.

Regards,
Sanjay
