ORA 12560 OTN Protocol Adapter Error

I installed Oracle 9iAS DB and Developer. When I tried to run Form (Form Builder). I could not establish the connection.
After insert username and password (without hostname), the error said, ORA 12560 OTN Protocol Adapter Error. However, when I put the hostname, the message alert 'the service name could not be solved' or sth. Can anyone help me with this problem? Thank you so much

Hey Nikhil,
I have the same problem, however when I try to run the commands u have asked to run I get errors.
When I try
c:>svrmgrl
'svrmgrl' is not recognized as an internal or external command.
operable program or batch file.
and when I start lsnrctl

I am using XP , the database is on other drive and the Developer suite is on other drive however, Listener is working fine. This error "ORA-12560: TNS:protocol adapter error" comes only when I try to log into my database from isqlplus. I am using 9i. Any Ideas on what should be done.

Help: Error message "ORA-12560 TNS:Protocol Adapter Error "

I tried to install Oracle 8i EE version 8.1.7 on Windows 2000. Everything is OK until the installation proceeded to installing "Oracle Database Configuration Assistant". At that point, I got an error message "ORA-12560 TNS:Protocol Adapter Error (network not loaded)". I looked up the error message. The cause of the error said: "This error occurs when the SQL*Net driver cannot find the JSB driver because you may have either forgotten to load the JSB driver (for instance MFTP) or used an incorrect TCP_VENDOR key (for example, TCP_VENDOR=NOVLWP).". And the suggested action said: "Load the JSB driver or use the correct TCP_VENDOR key.". I am using a standalone PC with Windows 2000 at home, and the PC does not connect to any network(except that I can dialup to internet via modem). What should I do? I can't understand the error message. Any expert to help me overcome the error?

Hi,
Did you check whether the windows service for listener is up and running? if not please start it, by typing "services.msc" in run window and start the service. Then check whether you have listener.ora file in $ORACLE_HOME/network/admin and also post listener.ora contents.
Regards,

Does anyone have any ideas what else I can check. I'm a Unix person, not a Windows person, which is making it even more complicated. If I was on Unix, I'd just blow everything away and start again from scratch, but since I'm not sure how to remove all traces from the registry, etc., I don't want to try that on this machine. There was already one other database created, but it's not goign to be used.
Any help would be greatly appreciated.
regards,
Tarisa.

hi,
thanks for the info. the problem, as it turns out, was that I was connected to the db server via a terminal service (Microsoft Management Console), which for some reason caused probelms with TNS. After I connected directly to the machine using VNC, I was able to create the database with no problems. strange but true.
regards,
Tarisa.

ORA-12560: TNS:protocol adapter error in Oracle Forms...

Hi, I installed Oracle developer suite to use for Oracle forms but am getting "ORA-12560: TNS:protocol adapter error" when trying to run a form. The database is running locally on my PC.
I've run the command line to see if hostname matches up with the "HOST= " in the ".../network/admin/listener.ora " file match, they do. What can I try next? I did have Oracle 10gXE installed, which I have now removed. I'm including my tnsnames and listener file content:
# tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora

Thanks in advance for any help!

Of course you found another one. Each .and every Oracle database client home (such as developer, app server) has one.
Don't just change the port - the tnsnames.ora in the dev home does not point to a database service. It only points to an extproc [external procedure called by a database]. You need to put a database service entry into that file similar to the one in the database home. (Easiest solution - copy the tnsnames.ora from db home ... after you've made a backup)
And please don't tell me you are using Developer 6i - a simple Google search would verify that the networking is incompatible.

TNS-12560: TNS:protocol adapter error (when starting database)

Hi.. everyone.
I am testing oracle9i and oracle10g on the same machine, windows xp pro.
When I was trying to start oracle10g using command line mode,
I got the error, TNS-12560: TNS:protocol adapter error.
I entered these command.
set oracle_home=10g_homexxxx
set oracle_sid=xxdb
sqlplus /nolog
conn sys/xxx as sysdba
I got the error, TNS-12560: TNS:protocol adapter error.
The install of two different versions of oracle , oracle9i and oracle10g,
on the same machine(windows xp pro) could cause this problem?
Is it safe to install two different versions of oracle on the same window machine?
Is there any confliction in environment variables?
I think there is no problem on the linux, unix system.
I stoped the listener of oracle9i and tried again. But I failed.
I am looking forwared to hearing your experience and advice.
Thanks in advance. Have a good day.
Ho.

Dear Werner.
Thanks for your reply.
I shutdown oracle9i and 10g, using "services.msc" utility from windows.
Therefore, "OracleService<xxdd>" is not running.
What I want to do is to startup 10g database using "cmd",command line mode.
In addition, I would like to know why I could not start 10g database, using "cmd"
on windows xp pro.
I installed 9i first and installed 10g. I think there are a kind of environment variable
conflictions.
I am wondering how I can fix them, and whether or not they are curable.
Thanks for your reply. Have a good day.
Regards.
Ho.

Tns-12560: TNS protocol adapter error on linux

I've installed an oracle 10g database on linux 4.6 in a VMWare image. After opening an x term window within the image, I'm getting a tns-12560 error when both running tnsping and opening a sqlplus session as a database user. The listener and database seem to start fine. I've included entries for sqlnet.ora, tnsnames.ora and ORACLE_SID and ORACLE_HOME values for my user.
mui> tnsping orcl
Used parameter files:
/pinmaster/newtools/oracle_10.2/linux/network/admin/sqlnet.or
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = cgbu-p731v2.us.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl)))
TNS-12560: TNS:protocol adapter error
From sqlnet.ora: NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
From tnsnames.ora:
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = cgbu-p731v2.us.<<my domain entry>>.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
This is from init.ora
# Database Identification
db_domain=""
db_name=orcl
Environment variables for the database user:
9mui> env | grep ORACLE_SID
ORACLE_SID=orcl
13mui> env | grep ORACLE_HOME
ORACLE_HOME=/pinmaster/newtools/oracle_10.2/linux

One of the more common issues causing 12560 is that the host in the listener.ora does not match current host name. Commonly caused by dhcp.
Your tnsnames.ora looks for cgbu-p731v2.us.oracle.com
Your listener.ora want to listen for cgbu-p731v2.us.<<my domain entry>>.com
Your hostname is ??? (enter 'hostname' at command line)

TNS-12560: TNS:protocol adapter error on Oracle Enterprise Linux

hi,
I am getting -
TNS-12560: TNS:protocol adapter error when I try to connect the Db installed on Oracle Enterprise Linux from other machines.
I made all the .bash_profile changes and created one shared listener also to check whether there is any problem with the dedicated default listener or its port.
Please suggest the solution .

You need to open the firewall on OEL.
Edit the contents of /etc/sysconfig/iptables file. I added the line in bold:
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT

-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 631 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A RH-Firewall-1-INPUT -m state state NEW -m tcp -p tcp dport 22 -j ACCEPT
*-A RH-Firewall-1-INPUT -m state state NEW,ESTABLISHED,RELATED -m tcp -p tcp dport 1521 -j ACCEPT*
-A RH-Firewall-1-INPUT -m state state NEW -m udp -p udp dport 137 -j ACCEPT
-A RH-Firewall-1-INPUT -m state state NEW -m udp -p udp dport 138 -j ACCEPT
-A RH-Firewall-1-INPUT -m state state NEW -m tcp -p tcp dport 139 -j ACCEPT
-A RH-Firewall-1-INPUT -m state state NEW -m tcp -p tcp dport 445 -j ACCEPT
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT
As you can see, my listener port is 1521.
Do not put that line after the line with REJECT keyword ( it won't work then) !
Save and close the file. Restart iptables:
/etc/init.d/iptables restart
Now you can connect from the outside.
It works on my OEL version 5 update 4.

TNS-12560: TNS:protocol adapter error - Of a different sort

Hi ,
Have a unique problem.
System :- Win 2K
I have installed 9iDB & 9iDS. They were working perfectly fine. I was able to connect to DB from forms. But due to some restrictions i had to resort to 6i forms.
Now i installed 6i forms on the same machine. But when i try to connect to DB i get the TNS:Protocol Adapter error. I am sure the instance and the listener is up and running. Because still i am able to connect from 9i forms. The DB name is MYDB.
The error i am getting is :-
========================
Fatal NI connect error 12203, connecting to:

Did you try copying 9iDS SQLNET.ORA and TNSNAMES.ORA to 6i Home ?

TNS-12560: TNS:protocol adapter error TNS-00530: Protocol adapter error

Unable to start listener service.
Running Oracle Database 11gr2 on Windows 7.
I just installed Oracle with the "install software only" option.
Already set up the instance, the database, the dictionary views, etc.
Created tsnames.ora, sqlnet.ora and listener.ora as shown below.
Before installing Oracle I followed the instruction on Oracle
documentation to install a Loopback Adapter.
It is set up as the primary adapter as indicated on the
instructions. The name is "gabylan" (previously the computer
name was "P4". I set up the "hosts" file as indicated, the oracle_hostname
variable, etc. as you will see below. I don't know if it's important to "uncomment"
the line on the "hosts" file for the "localhost" entry, I left it
as it was originally.
Services currently in "Started" Status:
OracleServiceorcl
Oracle orcl VSS Writer Service
OracleMTSRecoveryService
OracleOraDb11g_home1ClrAgent
