Hello everyone,
I am a new to learning Oracle 10g and I recently installed Oracle 10g on XP Professional. When I went to log in to SQL Plus from the command prompt after I enter sys for the user and after I tried to enter in my password I received and error:

ORA-12560: TNS:protocol adapter error

Can anyone explain in detail how I can fix this error? I am still learning and trying to get more familiar with Oracle.


thanks,
techy1

Did you download and install the correct version for your operating system?

Did you install the database, not just the client?

Did you get any errors during installation?

Windows sometimes has problems starting all the services. Go to your control panel, then select administrative tools, then select services. Look for any services that start with the word Oracle and start them, if they are not already started.

>ORA-12560: TNS:protocol adapter error

SQL*Net is NOT required to connect to DB while logged onto DB server system directly.

Be logged onto DB server as same OS user who own Oracle software
open command window

CUT lines below then PASTE into open command window

set
sqlplus
/ as sysdba


CUT commands & results from command window then PASTE all back here

Hello Barbara and thanks for your reply,
yes I installed the correct version,
yes I installed the database first then the client,
no I did not receive any errors during installation,
and yes I made sure that all of the services were started and I am still receiving the error. Any more ideas?

Thanks Blackswan the tns error is preventing me from signing into sqlplus from the command prompt so I am unable to log in and enter the command. Any more ideas please?

Copy and paste EXACTLY what happened when you ran these commands (At the command prompt, not in the SQL prompt)

set
sqlplus "/ as sysdba"

Why don't you post what is asked?
BlackSwan asked for "SET" not "tnsping oraclass" which is irrelevant for a local connection.

AND DO NOT POST IN UPPER CASE, THIS IS SHOUTING ABOVE ALL WHEN YOU POST IT IN BOLD.

We don't care what you verified, we want to see it.

Michel

For anyone who read my last post please excuse the all bold caps I am new to this forum and Oracle and I was not meaning to shout or be disrespectful. I was just trying to make my message more clear and easy to read between my comments and the message results so please dont be offended or take my message out of context. Sorry again and it will not happen anymore.

Received the following message from techy1

The reason I wrote in all caps and bold was to make my message easier to read and to try to distinguish my comments from the error messages. Like I said before I am new to Oracle and this forum I was just trying to get some help not get into an argument or start some drama which is why I dont understand why you would start with me I dont even remember corresponding with you in the first place. If you had a problem with my post then all you should have done was ignore it or you could have private messaged me like a mature adult as I did you. I am just here trying to learn and brainstorm not get caught up in mature drama and get disrespected by you Michel. I am an adult trying to do something and I dont have time for games. So from now on do not post on my topics or respond to anything concerning me. Just leave me alone and keeps your rude negative comments to yourself since you do not know how to talk to me nicely or with respect.


1/ As moderator I have to point out poster to forum guide when it is violated.
2/ You should read this OraFAQ Forum Guide before posting.
3/ Posting in upper case meaning is true in ANY forum since newsgroup existed more than 20 years ago.
4/ I don't think my post is rude or negative, but I think your behaviour is:
4b/ When someone asks you to post something to help you it is showing respect to answer her, and disrespectful to ignore this, despite what you say.
5/ You have not to say to anyone if he can post or not and when.

As he know ignore me, please quote my post to let him know how disrespectful, rude and childish it is to send a mail and don't allow the addresee to answer.

Regards
Michel
