We have our Remedy database on Oracle 11.2.0.3.0 - 64bit Production server.
I am using SQL*Plus Release 10.2.0.1.0 client to connect to it but am unable
to connect with a connection error that reads as:
ORA-12154: TNS:could not resolve the connect identifier specified
I have checked my tnsnames.ora file for any possible errors in the
connection string and can't seem to find one. This is the contents of the
entry (I have replaced the actual IP and the service name and what not with
fictitious names for security reasons - the port is 1521 which is the
default port.)
## Remedy ITSM db - Devl - Used IP instead of hostname
CONNENTRY =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 111.111.11.111)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = connentry)
)
)
While connecting I use the username & password as given to me and connentry
as the host string.
What could possibly be the causes of ORA-12154 that I ought to check for? I
suspect something wrong with my connection string in my tnsnames.ora file
but can't figure what it is. I checked with the DBA's for the exact IP,
port, service name and they say it all checks out.
I was also suspecting that perhaps Oracle client 10.2.0.1.0 may not be
compatible with Oracle Database version 11.2.0.3.0, but I do not think that
could be the problem as Oracle clients are usually compatible with at least
1 version forward or backward.
Any insights as to what I and my DBA's may be missing may help..
Thanks..
Joe
