Qian Dong: "Although I evaluated Oracle Maestro for only a couple of days, I must say I like what I saw in this product. I am going to place an order for this product.

Thank you for the good work".
Laurits Sogaard Nielsen: "Oracle Maestro (and also MS SQL Maestro) are the perfect substitutes for TOAD and in some ways also much better products (they are much cheaper, and the support is fast and easy). I'm looking forward to getting much more experience with both products, that already now have proven themselves to be fantastic".

Public database links

A database link is a schema object in one database that enables you to access objects on another database. The other database need not be an Oracle Database system. A public database link is available to all users.

 

 

New public database links are created within Create Public Database Link Wizard. In order to run the wizard you should either

 

select the Object | Create Database Object... main menu item;
select the Public Database Link icon in the Create Database Object dialog

or

select the Public Database Link list or any object from that list in the explorer tree;
select the Create New Public Database Link... item from the popup menu

or

open the schema in Schema Editor and the Public Database Links tab there;
press the Insert key or select the Create New Public Database Link item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

       

To create a new public database link with the same properties as one of the existing public database link has:

 

select the Object | Duplicate Database Object... main menu item;
follow the instructions of Duplicate Object Wizard.

 

 

 

Public database links can be edited within Public Database Link Editor. In order to run the editor you should either

 

select the public database link for editing in the explorer tree (type the first letters of the public database link name for quick search);
select the Edit Public Database Link ... item from the popup menu

or

open the database in Database Editor and the Public Database Links tab there;
select the Public Database Link to edit;
press the Enter key or select the Edit Public Database Link item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

       

You can change the name of the public database link using the Rename Public Database Link dialog. To open the dialog you should either

 

select the Public Database Link to rename in the explorer tree;
select the Rename Public Database Link item from the popup menu

or

open the database in Database Editor and the Public Database Links tab there;
select the public database link to rename;
select the Rename Public Database Link item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

 

 

 

To drop a public database link:

 

select the public database link to drop in the explorer tree;
select the Drop Public Database Link item from the popup menu

or

open the schema in Schema Editor and the Public Database Links tab there;
select the public database link to drop;
press the Delete key or select the Drop Public Database Link item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar)

 

and confirm dropping in the dialog window.
