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!

Database link throws ORA-02085 on one database, but none of the others

Asked by AptDev in Oracle 8.x, Oracle Database

Tags: Oracle, Database, 8i

I use DATABASE LINKS on my reporting database, against each of several other Oracle 8i databases.  All of the database links are working fine... except one.  

Many of the databases, including the reporting database, and the offending database, are on the same server.

I rebuild each database link, logging on to my database REPORTING.enterprise.com, an running the following set of queries:

ALTER SESSION SET global_names = FALSE ;

ALTER DATABASE RENAME global_name TO anything.ENTERPRISE.COM ;

DROP PUBLIC DATABASE LINK DB6.ENTERPRISE.COM ;

ALTER DATABASE RENAME global_name TO REPORTING.ENTERPRISE.COM ;

CREATE public DATABASE LINK DB6.ENTERPRISE.COM  CONNECT TO myuser IDENTIFIED BY mypwd USING 'DB6.ENTERPRISE.COM' ;

ALTER SESSION SET global_names = TRUE;


When I go to run a query against the database links, this is what I get:

select * from currency@DB5.enterprise.com
3 row(s) retrieved

select * from currency@DB6.enterprise.com
[1]: (Error): ORA-02085: database link DB6.ENTERPRISE.COM connects to PROD2.ENTERPRISE.COM

Now... it's true that the database DB6 was created from an export of PROD2... but so was DB5.  Why would one of them fail, while the others succeed?  And the DatabaseLink to the original production database PROD2 works just fine.  What would make the link to one of the databases (created from an export of that production machine) fail, while the links to other databases (created from exports of that same production machine) work just fine?

Any ideas?
