When I use the command:
sqlplus username#ip_address:1521
I get the error:
ORA-12154: TNS:could not resolve the connect identifier specified
When I set ORACLE_HOME to /cygdrive/c/oracle/product/10.2.0/client_1, I get a different error:
Error 6 initializing SQL*Plus
Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
I can telnet to the server's port 1521.
I also tried the Windows path for ORACLE_HOME but it gives me the same error, also in Cygwin when I change the $PATH = $ORACLE_HOME/bin no command is recognized.
I am able to connect to this database via a excel macro but not using cmd.exe or Cygwin .
If you don't want to use TNSNAMES.ORA to specify the connection parameters you need to provide them on the command line. This works with the widest variety of SQLPlus versions.
sqlplus OraUser/OraPassword#'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=remoteServer)(PORT=1521)))(CONNECT_DATA=(SID=OraSid)))'
Note ' is for Unix and needs to be changed to " for Windows.

Every time I try to run the following sqlldr command on a terminal only oracle 19c system:
sqlldr username/password#$HOSTNAME/$ORACLE_SID control=rules.ctl log=backup_error_logs.txt data=output.csv errors=1000000
I get the following error message:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Things I have tried:
Verified that the listener is operable and listener.ora file is properly formatted with lsnrctl.
Verified the connection and oracle environment variables are working as the following sqlplus command runs without problem:
sqlplus username/password#$HOSTNAME/$ORACLE_SID
Verified the tnsname.ora is running properly configured with the following tnsping command:
tnsping $ORACLE_SID
Cannot think of anything else to try or to check. Does anyone have any advice without resorting to the GUI tools?
Could be a problem of quotes in the variables, the behavior of both tools is different regarding quotes.
I am trying to connect to a database in a shell script. I can connect fine if I use this:
sqlplus user/pass#db_service_name
However, when I try something like this, it is not working:
ORACLE_SID=db_sid
export ORACLE_SID
sqlplus /nolog
connect user/pass
I get an error:
ERROR:
ORA-12545: Connect failed because target host or object does not exist
Obviously I am missing something, but this is an area I am not fully familiar with, so I am not sure where I am going wrong. My assumption was that if I set the ORACLE_SID, that I would not need to identify my db when connecting in sqlplus. Is my assumption incorrect? Or am I missing some required step or configuration?
Using sqlplus user/pass#db_sid refers to a TNS alias in $ORACLE_HOME/network/admin/tnsnames.ora. If the instance is running on the same host as your sqlplus command, then you need to look at the text of the TNS alias in tnsnames.ora and set ORACLE_SID to the SID referenced in the file and then execute . oraenv. If the instance is not running on the same host as your sqlplus command, then your latter attempt will never work.
If you want more secure connections, you might consider using a wallet.
I want to connect with my Oracle database without installing Oracle Client.
I downloaded:
"Instant Client Package - Basic" and
"Instant Client Package - SQL*Plus"
Then I created folder on C:\Oracle\instantclient, where I extracted all packages.
I have been set system environment like:
Path - C:\Oracle\instantclient
NSL_LANG - with properly key
ORACLE_HOME - C:\Oracle\instantclient
ORACLE_SID - C:\Oracle\instantclient
TNS_ADMIN - C:\Oracle\instantclient
Then I created tnsnames.ora file with configuration in C:\Oracle\instantclient
and when I puted a command to cmd:
sqlplus user/password #HOST
I have a message like:
ERROR:
ORA-12560: TNS:protocol adapter error
but when I tried like:
sqlplus user/password#(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(Host=address to host)(Port=1521))(CONNECT_DATA=(SID=address to SID)))
everything works properly. Why SQL have a problem with recognize tnsnames.ora file?
Your command should be:
sqlplus user/password#HOST
with no space between the password and #HOST part.
With the space it treats the #HOST as a script to execute once you've logged in, and it tries to connect locally, which produced that TNS error. (As you don't log in the HOST isn't ever evaluated to establish if it exists, so it's effectively noise at this point).
C:\>sqlplus -l -s x/y #HOST
ERROR:
ORA-12560: TNS:protocol adapter error
SP2-0751: Unable to connect to Oracle. Exiting SQL*Plus
With the space removed it looks for HOST as a TNS alias:
C:\>sqlplus -l -s x/y#HOST
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
SP2-0751: Unable to connect to Oracle. Exiting SQL*Plus
For me that still gets an error since I don't have HOST in my tnsnames.ora, but it's a different error and you can see it's at least trying to use it as a TNS alias. If you have it defined properly it will be able to connect to your database.
NEVER edit $ORACLE_HOME/network/admin/tnsname.ora manually, use "netmr" to create Local Name.
Don't know why it's same but do not work.
This commando works fine for me:
sqlplus /nolog
connect username/password#hostname:port/SERVICENAME
In my ruby script, I set to connect to oracle db via:
conn = OCI8.new(username, password, database)
It works well on my own desktop (Ubuntu), however, when I deploy it onto a lab machine (Ubuntu VM), it has oracle connection error. The machine has all oracle drivers needed because I can connect to it by commandline sqlplus. Also I did echo $ORACLE_HOME and it's set correctly.
The error is like:
env.c:257:in oci8lib.so: ORA-12154: TNS:could not resolve service name (OCIError)
I had the same error on my desktop when ORACLE_HOME was not set correctly. Once I set it right, it started to work. But on this lab machine, although I can launch sqlplus w/o problem, I can't connect via ruby script. Any advice?
The ORA-12154 error means that the value of the "database" argument in your OCI8.new call is not being found in the tnsnames.ora file that the environment is using. This could be due to:
an incorrect value being passed through the variable
something in the environment that is
pointing to the wrong location for
tnsnames.ora. By default it should
be in $ORACLE_HOME/network/admin, but
this can be overridden by the
TNS_ADMIN environment variable.
You say that you can launch sqlplus on the lab machine without any problem, and I assume that this means you can connect to the database of interest when you do this. If this is the case, it seems that the environment present when you run the Ruby script must be somehow different.
I'm trying to use cygwin sqlplus to connect to a remote oracle installation located at myserver.mycompany.com port 1530. When I try
sqlplus username#myserver.mycompany.com:1530/orcl
I get the error:
ORA-12154: TNS:could not resolve the connect identifier specified
When I set ORACLE_HOME to /cygdrive/c/oracle/product/10.2.0/client_1, I get a different error:
Error 6 initializing SQL*Plus
Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
I can telnet to the server's port 1530, and the SQL Developer installed locally is also able to connect to the database. What am I doing wrong?
I wasn't aware there was a native cygwin client for Oracle (correct me if I'm wrong here but I can't find any mention of it on Oracle's web site either). If you're using Cygwin with the Windows client you need to use a native windows path. It won't understand your /cygdrive path.
However, I have used Win32 Oracle clients with cygwin and made it work - the same shell scripts would work on Cygwin, Linux and Solaris.
There isn't a cygwin Oracle client. As above answer, use the ORACLE_HOME set to the windows path.
For the first half of your question, try seeing what the TNS_NAMES env variable is set to, and if not set, you may need to try setting it to the correct place. Usually it defaults to %ORACLE_HOME%/network/admin/tnsnames.ora . SQL Developer keeps it's own copy of the tnsnames file, so you can't reply upon that to fix the problem.
Combining the details from the other answers (which took me a little, so I post it as separate answer instead of comments):
The $ORACLE_SID and, if set, $TNS_ADMIN (and probably other path-related Oracle variables) must use Windows-paths. Your Cygwin $PATH variable should of course use the Cygwin notation (/drives/c/…). So I've included into my .bashrc:
export ORACLE_HOME=c:\\Oracle\\product\\12.1.0\\dbhome_1
export TNS_ADMIN=d:\\Oracle\TNSAdmin
export PATH=$PATH:$(cygpath -u $ORACLE_HOME)/BIN
After that, I had no more issues calling e.g. tnsping or sqlplus. As the above is just an example, you must of course adjust the paths to reflect your installation/configuration :)
NXC is right - it wasn't a cygwin client I was using, but the windows sqlplus client.
I set the windows environment variables for ORACLE_HOME and ORACLE_SID and was then able to run sqlplus in a cygwin bash shell using the net_service_name from tnsnames.ora.
The way it worked for me was to remove /cygdrive/d or /cygdrive/c and replace them with with d:/ or c:/ and then your sqlplus call within cygwin session will work. The /cygdrive/DriveLetter is confusing it.
I have same error like you,
you should set not only ORACLE_HOME in windows Variables,
But also PATH include %ORACLE_HOME%\bin
then you can open windows cmd,
try sqlplus username/password#your_define_tnsname
if okay, then remove all ORACLE PATH setting in cygwin, restart cygwin,try it.
if failure, should let sqlplus works well in windows cmd at first
I have TNS_ADMIN variable configured and it works properly in Win Environ
I used cygpath mnodification in .bashrc
If TNS_ADMIN is configured add following row to .bashrc
export TNS_ADMIN=$(cygpath -m $TNS_ADMIN)
