[TNS-12560: Protocol Adapter Error] after every 48 Hours

Dear All,
Our company encountered a very strange Oracle database issue, here is the details:
Environment
1. Dell 2950 Server with Windows Server 2003, Oracle 9i 9.2.0.1 and WebLogic Platform Server 8.1 SP3 installed;
2. Two databases on the Oracle, one is called FAX and it is a schema located in the original DB database; another one is called EIP, it is a new database created by IT staff;
3. Two applications installed on this server, the first one is a Visual C++ developed Avaya Call Routing system (BCCS), this system will query data from the EIP database; Another one is a WebLogic and JAVA based system (EIP), users access this system by using IE at client computer and this system also uses the EIP database;
4. We have a standalone fax-out server with faxboard installed and used to send fax, this server uses the FAX database;
Issue
1. Before Jun.6, everything is OK;
2. At Jun.6 night, we installed two new applications on two new server, these applications will read and write data to the EIP database via network;
3. Jun.9 12:30, we found the BCCS cannot connect to the database, error message is [TNS-12560: Protocol Adapter Error], we checked and found all Oracle's services are running properly including the TNSListener;
4. We reboot the server and then everything is OK;
5. Jun.12 10:41, Jun.14 12:46 and Jun.16 20:51, same issue occurred again, we simply reboot the server and everything is OK
It is very interesting that we found the issue always occur after 48~55 hours we reboot the server, but cannot find more useful information; there is also no failed information in the Oracle alert log.
Please share some ideas with me, thanks a lot.

Thanks for reply. Answer to your questions:
1. This issue occurs on application which were installed on the computer with Oracle installed, and there is no firewall on this computer, so I believe that it is not related network.
2. Please let me know how to check the error stack and turn on tracing.
3. ORA file info:

Tns-12560 protocol adapter error linux

I m running two independent oracle 11g on red hat 5 in vmware workstation 7 which is sitting on window xp where i m running 10g.
I was facing a lot of networking when using tnsping. during my search i found that SUlinux and firewall was on which i turned off.
My problem solved.
My question is Whether it is feasible in industrial environment to turn off the Firewall and security of Linux.
My second problem is:
I did everything using orapwd on oracle 11g on red hat. .
but i m getting the same result
select * from v$pwfile_users;
no rows selected
My warmest Regard.

My question is Whether it is feasible in industrial environment to turn off the Firewall and security of Linux.When you say "security of linux" are you referring to SELinux? You can turn it off, or set it to a less restrictive mode. As for the firewall, there is no need to turn it off, just configure it correctly.
My second problem is:
I did everything using orapwd on oracle 11g on red hat. .
but i m getting the same result

We have no way of knowing exactly what "everything using orapwd" means on your system. You are asking us to explain something we cannot see.

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
OracleServiceorcl
Below is a summary of the error message and some information
about my system setup to help you diagnose my problem.

Can anyone help me?

Ok, I made all the things that you say: installed Oracle sw, installed the Opatch end started SAPinst.
But SAPinst stops when configuring oracle server network. I really don't understand what to do. If i write the command of LSNRCTL and tnsping the DEV (my DBsid) i have the following error:

Regd ORA-12560 Protocol Adapter Error

Hi Firends,
I am new to Oracle.I just installed oracle 8i Personal Edition on Windows 2000.
Now I want to use SQL Plus but it is promting me for username, password and Host String.
I typed Scott,Tiger for USername and for Password but I don't know what to type for the Host String. It says "ERROR ORA:12560 TNS:Protocol Adapter" and then it kick me off. Could anyone tell me how to get into SQL*Plus?
Thanks
Peru

I don't know the solution.
This is the forum for a specific Oracle 10g product called "Instant Client".
If you post your question to the Installation forum at
http://www.oracle.com/forums/forum.jsp?forum=64
you may find someone who knows the answer.

Hi everyone,
I setup oracle11.2 for the first time without DB creation. I work on windows7. To create my DB while activating the entreprise manager, it ask me to create a listener using necta. When I execute it, the listener is created, but I cannot launch it. When I execute the LSNRCTL start I have:
TNS-12560 erreur d'adaptateur de protocoleTNS-00530 erreur d'adaptateur de protocole
The created files are:
Listener.ora:
# listener.ora Network Configuration File: D:\app\Me\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

)The sqlnet.ora is:
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES = (NTS)When I execute the tnsping with the adress given in listener.ora I have:
TNS-03505 echec de la resolution du nomIt seems to be a common problem, but unfortunatly I can't found a solution that works.
I m waiting for any help. thnx.

I have found only the oraInstall.out and the oraInstall.err but not .log
oraInstall.out is the following:

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 :-
========================

Oracle is a bit touchy with tnsnames.ora spelling. I copied your entry, just changing names :
MYDB =

(CONNECT_DATA =

(SERVICE_NAME = orcl)

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

TNS-12560: TNS:protocol adapter error Windows XP

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

Any suggestions for how to fix this error?

What's the status of the corresponding Windows service? OS error 1058 means normally service is deactivated. In the worst case it could be necessary to remove the service from the registry. Afterwards reboot the machine and recreate the service by 'lsnrctl start'.

Are your oracle services logging on as localhost? cause if they
are that may be your problem. change the log on user to your
local administrator with their password (i.e.
administrator/******). Oracle DB and the other services have a
problem starting up with the localhost. they appear to startup
but don't actually startup.

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.

Thx.

Yes, the XP firewall is running. During the Oracle instalation it poped up twice, but I selected 'Unblock'. I can't turn it off because it is running using the domain settings, but I can add exceptions (programs or ports). Port 1521, tnsping or sqlplus are not blocked and there is an option 'Display a notification when Windows Firewall blocks a program' witch is checked.
