The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

I Can't Connect to Oracle via TOAD - ORA-12545

Asked by F-J-K in Oracle 3rd Party Tools, Oracle 10.x, Databases Miscellaneous

Tags: toad, oracle, ora-12545

First of all, i have Oracle 10g installed in my PC, so i'm just connecting to the db locally for educational purposes. I always logon as SCOTT.

Ok, I have Oracle 10g already installed long time ago. I used to access it via SQL Developer, now i moved to new place so the IP is changed, i can't connect with SQL Developer! Even though I can not connect to the Database via SQL Developer, i can connect to the database via SQL*Plus successfully. Also, I can connect as sysdba from SQL*Plus.

The error i get in SQL Developer, "Socket is not connected".

Here is my problem:-

I downloaded TOAD, i put username as SCOTT and password 123456.

In "Database" field there are:

- EXTPROC_CONNECTION_DATA
- ORCL

In the white box at the left side, there is nothing.

In "Connect Using" list, there are:

- (Oracle Root)
- OraDb10g_home1

I entered username as SCOTT and password as 123456. "Database" set to ORCL. "Connect Using" is OraDb10g_home1. I get this error:

ORA-12545: Connect failed because target host or object does not exist

-----------------------------------

Afterwords, i did:

C:\Users\User>tnsping orcl

TNS Ping Utility for 32-bit Windows: Version 10.2.0.3.0 - Production on
009 02:58:28

Copyright (c) 1997, 2006, Oracle. All rights reserved.

Used parameter files:
D:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST =
PC.gateway.2wire.net)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED)
E_NAME = orcl)))
TNS-12545: Connect failed because target host or object does not exist

C:\Users\User>

---------------------------------

As you see i don't get any IP back: TNS-12545: Connect failed because target host or object does not exist

************************************

Extra Info:

Here is my Oracle 10g Enterprise installation info:

I have installed this version "Oracle Database 10g Release 2 (10.2.0.3/10.2.0.4) - Enterprise Edition for Microsoft Windows Vista and Windows 2008".

username: scott
password: 123456
host string:

Global DB Name: orcl
System Identifier (SID): orcl
Server Parameter Filename: D:\oracle\product\10.2.0\db_1\database\SPFILEORCL.ORA

*************************************************

Any help will be appreciated.
