With Oracle SQL-Developer I'm able to connect to my VMware CentOS 7 Oracle database ORCL.
if I try to connect with SQLPlus I'm told the realm doesn't exist.
Any idea as to why I can connect with Oracle SQL-Developer and not SQLPlus on the same machine?
TNSPing resolves the SID/Service name without any problems.
C:\oracle\ora11g\11.2.0.2\network\admin\sqlnet.ora

Here's the output from the SQLPlus connection attempt from the same machine that SQL-Developer is working without any issues.

Your sqlplus command, try this:
sqlplus user/password#192.168.1.50:1521/ORCL
In SQL Developer, once you're connected, run this:
show tns
show connection
Make sure you're actually trying to connect to the same database in SQLPlus, also make sure your $ORACLE_HOME and $ORACLE_SID are properly configured.
This looks like something is wrong with Oracle_Home or your listener.
Could you please - - LSNRCTL and check the status of the same.
If it is fine, then try to connect to sys:
sqlplus /nolog
conn / as sysdba

I'm getting started with Oracle Personal Edition. Installation was successful. Trying to connect to the database and getting stuck. I have:

At this point, I'm stuck. How do I troubleshoot and resolve the cause of the error message?
Your listener is on and working but your instance has not dynamically registered it’s services with it nor are they statically part of your listener config.
Easiest option is to get your instance to register itself. Look at the instance parameter local_listener, this needs to point to your listener running on (HOST = host.docker.internal)(PORT = 1521), you can do this with a tnsname that points to the same listener or you can take advantage of EZConnect syntax and just use the host name (the default port is 1521 anyway). I would recommend setting up a tnsnames entry just called listener which contains the host and port but no connect_data.
(Using EZconnect)
Alter system set local_listener='host.docker.internal';
This will self-validate .
You then just need to wait for automatic registration to occur, you can see this happening in your listener logs, you can trigger it manually with alter system register; and you can confirm it’s happened by looking at the results of lsnrctl status host.docker.internal.
I would like to connect to the running "orcl" Oracle database.
I don't have much experience on the Oracle administrator. I installed Oracle 12c in a Windows Server, as I see the "Oracle", "OracleOraDB12Home1TNSListener" and "OracleServiceORCL" services are started in the machine.
I added the following to the "tnsnames.ora" file:
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1539))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
I get "Ok" result from executing the "tnsping orcl" command.
I can login with "sqlplus / as sysdba" and when I query with "select name from v$database" command, I see "orcl" database is active.
But when I try to connect to the "orcl" database using Sqldeveloper, or when I execute
"sqlplus -L "system/password#(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1539))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))"
I hit the issue below:

How can I connect to the orcl database? What I am missing in configuration or anywhere?
i think what you want is just
sqlplus [user]/[Password]#[connect identifier]
eg. your user is system, Password is pswd and connect identifier in your example is 'ORCL'
so your sqlplus command would be:
sqlplus system/pswd#orcl
if you DB is installed on your local machine that it should be also be possible just to conect to localhost instead of service
sqlplus system/pswd#localhost
I have a baffling problem. I have an Oracle 11g set up on Linux that was working fine. I was able to connect remotely from other machines using a SID based connection string such as
sqlplus myschema#192.168.184.102:1521:orcl
then for some inexplicable reason it stopped working. I'm not sure what I or someone else jiggled loose.
now i'm only able to connect remotely using a SERVICE_NAME or TNSNAME based methods
sqlplus myschema#192.168.184.102:1521/orcl
sqlplus myschema#ORCL
Both work and this would be fine and well, but I have applications that rely on SID connection pattern that I can change. Could some kind soul help me figure out what I'm missing

Since you can connect with your TNS alias, and that is using the SID in the connection description, the SID is working.
But your EasyConnect string is incorrect. From the SQL*Plus documentation:
The easy or abbreviated connection identifier has the syntax:
[//]host[:port][/service_name]
You cannot use the SID with Easy Connect, only the service name; so your connect using:
sqlplus schema/xxx#192.168.184.102:orcl
or even
sqlplus schema/xxx#192.168.184.102:1521:orcl
... can never have worked. You can use that form with a JDBC URL using the older style:
jdbc:oracle:thin:#192.168.184.102:1521:orcl
... but that is not the same thing as an SQL*Plus connection, despite looking similar.
If you're trying to check if a JDBC connection of that form will work, you cannot do so with SQL*Plus, but your TNS alias check is verifying it is set up as you expect anyway - as long as it uses the same host, port and SID. It would probably be better to use the newer JDBC syntax, but from the question it sounds like you can't change that.
Read more about Easy Connect.
This could be when Oracle cannot resolve the hostname to IP. Can you resolve your hostname with nslookup? I.e.,
nslookup yourhostname
Also make sure reverse lookup is working:
nslookup yourIpAddr
Windows 7, Oracle 11.2.0.1; it used to be working fine, not sure what happened lately. But I am not able to connect to SQL plus using sqlplus, and entering user name and password.
SQL Developer is working fine. Also the following command is working fine:
sqlplus system/system#//localhost:1521/ORACUSTOM
Though the above command is working fine, some of the scripts are not working (as these scripts try to connect to a different database. So I need to make the following work:

I'd appreciate if you can explain why one approach is working and the other is not.
The jdbc connection string
sqlplus system/system#//localhost:1521/ORACUSTOM
indicates that the service name 'ORACUSTOM' is used as the service name. Check the tnsnames.ora file for the right TNS name & ensure that it uses 'Oracustom' as the service name
In your case the TNS name should be something like
orcl =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(Host = localhost)(Port = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = oracustom)
)
)
With this entry in tnsnames.ora, you'll have to enter system#orcl as the username
(PS: Don't login as system. Bad idea.)
I am getting an error while trying to connect to oracle DB on the server throught Toad. The error message is :

Everything was working fine till yesterday but today my server got restarted and i am not ablt to connect to DB. I tried tnsping as well and it is working fine:

Still oracle throught toad is not working. Can anyone help me in solving this.
This error usually happens when your oracle services are not running. You will see the services by names "Oracle..TNSListener" and another service with name "OracleServicesim" in your services.msc. Check if both of them are running, or restart both those services. Then try to connect. It should work fine.
