Re: Dblink in Oracle10g

Bradd tested both methods and both work fine (note "identified by values" clause in #2). So, it seems to be a matter of preference.

I think step 1 will be ok..because in 10g we will not be able to get dblink password from sys.link$, password will be in hexadecimal format

You may want to look at how datapump handles this in 10g. If memory serves (queue the Iron Chef music), datapump now uses the same syntax as 'create user identified by values 'HASH'); 

I see two ways to accomplish this:
1. use Datapump to export the database links.
     PARFILE would look something like this:
              CONTENT=METADATA_ONLY
              FULL=Y
              INCLUDE=DB_LINK

    you can then use datapump to import into your dev database.

2. I did a quick test of this with a database link and it worked.
      select name,userid,passwordx,host from sys.link$;

   I then constructed a create statement:
create database link <name> connect to <userid> identified by values '<passwordx>' using '<host>'; 
   I was able to use the link.

I think method 1 is a lot cleaner, however.

Hi Gurus,
I have a requirement. I need to drop all the DB links in the Development database and recreate them as of Production database. How can i do that... Am aware on oracle 9i we can use dynamic script to create dblink by querying sys.link$. How can I over come this in 10g
