ORA-12560 Error Code

Hi,
Thank you for responding. I tried Scott/Tiger and I get the following error message:
ORA-12560 TNS: Protocol adapter error
Please advise me what needs to be done to get into SQL, I'd appreciate it very much.
Thanks again

It sounds like the Net8 listener isn't running. If you're running Windows, start the service and try again.

ORA-12560 Error

I installed 9i Developer Suite. I did not install the net configuration manger. The installation said it was not required. I am using forms builder and can compile the form. I connect to the database. However, when running the form I receive a ORA-12560 error. Also, the logon appears and I am prompted to connect to the database. Any help would be greatly appreciated.

The URL looks quite strange to me:
http://lap_top:8888/forms90/f90servlet?form=E:\cis355@userid=scott\tiger@buffer_records=no@debug_message
Looks like the "@" is used to separate the parameters which is new to me. Normally it's either "&" or "+". You can set the separator somewhere, cannot thou remember where? Registry? Also the userid isn't complete. The database name is missing, and even if it was there. How could the server know what's what? I mean, connect is done by user/pass@db, and if "@" is used as a separator...
Try this URL:
http://lap_top:8888/forms90/f90servlet?form=E:\cis355.fmx&userid=scott/tiger@orcl

Forms Developer: ORA-12560 error message

I am a novice Oracle 10g user, and have reached a dead-end regarding opening an existing form (.fmb) in Forms Builder. The ORA-12560 error message is generated:
"TNS protocol error". Consulting OTN, I learned that the Oracle SID service is required to be started for a form to be displayed in a web browser. When I checked the services window in XP Professional, I found OracleServiceOrcl to be started. I also specifed iexplore.exe to in the Runtime tab in Forms Builder Preferences. Any assistance with this issue will be appreciated.

ORA-12560 error in VS2010

I'm getting "ORA-12560 TNS:protocol adapter error" when trying to Add Connection in VS2010 (Server Explorer > Add Connection > Username: hr, Password: hr, Data source name: Local Database). This is sample HR database in Oracle XE 10g.
I'm guessing this could be something related to installation? My installation was like this: Oracle XE 10g which I've been using for couple of weeks. I then installed VS2010 Ultimate x86 followed by ODT with ODAC 11.2. This is on Windows 7 Ultimate x64. I've noticed that ODT is installed in D:\app, while XE is in D:\oraclexe.
I can access my database through APEX interface. Running 'sqlplus' in command line issues same ORA-12560 error. Running 'Run SQL Command Line' from Start > Oracle XE 10g works. This obviously points to wrong configuration / installation, but how to fix it?
Thanks in advance.

This obviously points to wrong configuration / installation, but how to fix it? That depends on the type of client connection initiated - local IPC connection (also called a bequeath connection) or a network (TCP) connection.
For a local IPC connection to work, the client driver needs to know the ORACLE_HOME and ORACLE_SID of the local database instance - this is usually set via the environment.
For a TCP connection to work, you need an Oracle Listener running on the Oracle server, the local Oracle database instance to have registered itself with the Listener, and for the client being able to connect to the Listener via TCP.
Oracle Listener is a service on Windows - but the command line program is called lsnrctl and via it one can start/stop the listener and determine its status and registered services. With the Listener running, the local database should automatically register itself with the Listener, unless one manually changed database or Listener parameters.
For TCP connectivity, the usual applies - firewalls must not block TCP access, the client needs to resolve the server hostname into an IP (if hostnames are used), that server IP must be reachable, etc.

Ora-12560 error with 8.1.7 under win2k

I have installed 8.1.7. on windows 2ooo. The install went
successfully and immediately after the install i could connect
with scott/tiger.
After a short period of time I can no longer connect and receive
the ora-12560 error. The system has not been rebooted or even
touched during this time period. I have removed the database
with dbassist and recreated. Again it works for 5 mins and
stops.
When I look at tsnrctl status all looks great. Under services
the tnslistener is working properly. I can do a tnsping as well.
I just cannot connect to the database.
Please help!

Dan Hoover An ORA-12560 WinNT is usually an indication that
the OS system/environment is not set up correctly.
You don't need a listener when you connect locallay without alias
name (sqlplus scott/tiger@alias).
Please try the following:
- start cmd box
- set ORACLE_HOME = <your home>
- set ORACLE_SID = <your SID>
- sqlplus scott/tiger

Ora (OCI) error codes for TAF failure

Hi,
I am working on project where in I have to support Transparent Application Failover (TAF) in GUI (using Java). From web (by googling) I found that this is automatically done by JDBC Thick (OCI) drivers.
I also found in some web site that there are lot of Ora Error Codes for various senarios like SELECT TAF failure(Ora 25401), or for DML command TAF failure(Ora 25402).
Is there any set/range of Ora(OCI) Error Code which is specifically for all TAF failure senario?
Thanks

Ora-12560 error on Ora11g after reboot

Having a major problem right now...
I recently set up a database under the following:
- Oracle version: 11gR2 (standard) 64 bit
- OS: Windows Server 2008, running on VMWare
- File System: ASM (through grid infrastructure)
Both the grid infrastructure and Oracle itself were installed under the same account. (This was a special local account that was set up and given administrator privileges.)
Everything was up and running, could connect and everything. I did make some changes (setting archive log mode).
I then did a reboot of the computer.
Now, whenever I try to connect as the sysadmin (sqlplus "/ as sysdba") or any other user, I get the following error:
Ora-12560: TNS protocol adapter error
I get the problem whether I try to access it locally or remotely. Enterprise manager also seems to not be functioning.
Any idea what the problem could be? I can do a TNSPing of the database, and the listener seems to be started.
There were 2 little issues that I'm nut sure are related:
- Although I installed everything under the same local admin account (I called dbadmin), when I go into lsnrctl I cannot use 'reload' (gives me a 'tns01190": user is not authorized to execute the requested listener command.) but I can use it if I sign in under 'administrator'
- When I looked the registry, the 'ORACLE_mydb_AUTOSTART' value was set to false. Could there be other parts that should be autostarting but are not?

You can also get that error with the database service started, the database up and running, but your did not set ORACLE_SID to the proper (or any!) value.

XE on CentOS: ORA-12560 error

I have just installed XE on a CentOS 5.2 system and can access the database using the Apex web page (database home page). I set the database HTTP properties to be accessible from local and remote. I am unable to connect to the database from a different pc, either using a web browser or thru SQLplus and am getting the generic 12560 error thru SqlPlus.
On the PC, I've put the server's IP address into a tnsnames entry pointing to the XE install there. I am sitting beside the server and can ping it, but still can't connect. Can I post the tnsnames entry?

On my PC, I have installed Oracle Database 10g Express Client. It does not ship a C:\XEClient\NETWORK\ADMIN\TNSNAMES.ORA file so I created one myself:
XE =
    (DESCRIPTION =
       (ADDRESS_LIST =
          (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.200)(PORT = 1521))
       (CONNECT_DATA =
          (SERVICE_NAME = XE)
    ) Works fine. Regards,
Georger

Sqlplus throwing ORA-12560 error while tring to login

Gurus I am having logon issue when I try to logon to oracle via sqlplus. I find the same error when I use impdp or expdp utilities from command line. The error I am getting is this "ORA-12560: TNS:protocol adapter error"
BTW I am using oracle 10.2.0 on Windows XP and Windows 2003 machine and in the past I was able to run impdp and expdp utilities successfully on these machines.
I double check every thing, and I have the proper tnsnames.ora and sqlnet.ora file on my network admin directories on both machines. I also check that all the required services e.g console, database service, TNSListenerService, isqlPlus service etc is running properly too. Besides this I don't have any problem logging in with EM or Oracle sqldeveloper.
Can some one please help and shed some light on this issue.
Regards,
RJ.

Gurus I just would like to add one more point here; is it possible that this issue can be caused by symantec antivirus services installed on these machines recenlty. The reason I am mentioning it is that I have tested every thing on another machine where we don't have symantec installed and every thing is behaving as expected.
To make thing more confusing even when I disable and stop all the symantec services on the machines where I am having this issue don't make any difference.

RJ.

I getting ORA-12560 error, how to rectify this

hai everybody,
I just try to shutdown my DB using shu it took time to stop and then i wait sometime but it will not shutdown so end that session.....
after that i am getting this error..
ORA-12560: TNS:protocol adapter error
plz anyone help me..

If you're running on windows you need to startup the database <b>"service"</b> before being able to connect to startup. It's advisable you use oradim to perform the startup and shutdown. Using oradim you can start the service and then the instance.

Get ORA-12560 error while accessing 11g database

Database version: 11.2.0.1.0
This is a development database running on CentOS. We had setup this database recently and everything has been fine. Today I noticed that when I connect to the database from remote, I get the following error -
ORA-12560: TNS:protocol adapter error
I'm able to get in to the database after logging in directly into the database server via putty. I have stopped & restarted the database, but with no help. I have checked the environment variables (ORACLE_HOME, ORACLE_SID) and they seem to be fine.
Can you please help on what might be the problem here? Is this something to do with some change in the OS firewall setting?
