Home -> Community -> Mailing Lists -> Oracle-L -> RE: tns-12545
Some questions for you:
What are you using to try to connect to Oracle?
Are you trying to use SQL*PLUS or and application that uses ODBC?
Is the user who can successfully connect on the same domain as you or
different domain?
Does you connection go through an oracle names server?
Can you post an entry from the sqlnet.log file that shows what happens when
the connection fails?
For starters, back up your tnsnames.ora file, get a copy of the tnsnames.ora from machine that connects and copy to your machine and try to connect. (Never mind that your tnsnames is correct... just try it). Some machines can have multiple copies of tnsnames.ora. Make sure you got the right one.
If the tnsnames has a hostname in the HOST= paramter then try using the IP address of the target machine instead.
Example1.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Host = Production1) <====<<< hostname
(Port = 1521)
)
Example1.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Host = 172.16.17.100) <====<<< use IP address instead.
(Port = 1521)
)
