TNS-03505: Failed to resolve name

[davey23uk]

I would start with a simpler example (see below) and I would change
the name of your machine to use an IPC address..

Test using ping ip_address first to make sure that works.

QAS.WORLD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ipc address here <#.#.#.#>)(PORT = 1528))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = qas)
)
)

Good luck

well all that is useless as it has nothing to do with the actual error, which is cannot resolve name

the reason is becuase your are doing a tnsping on qasst but your tnsnames has qasst.world
