I'm getting the "ORA-12154: TNS:could not resolve the connect identifier specified" error connecting to a database.

Make sure that "TNSNAMES" is listed as one of the values of the NAMES.DIRECTORY_PATH parameter in the Oracle Net profile (SQLNET.ORA).
Verify that a TNSNAMES.ORA file exists and is in the proper directory and is accessible.
Check that the net service name used as the connect identifier exists in the TNSNAMES.ORA file.
Make sure there are no syntax errors anywhere in the TNSNAMES.ORA file. Look for unmatched parentheses or stray characters. Errors in a TNSNAMES.ORA file may make it unusable.

I keep on getting the "ORA-XYZAB" error.

Please try to find an answer at http://ora-XYZAB.ora-code.com/ (of course you have to use your error code instead of XYZAB).

I'm getting the "Initialization error Could not locate OCI dll" error message connecting to a database.

First of all, please make sure that you have installed an Oracle client software. Next, you can either copy Oracle libraries from ORAHOME folder to ORAHOME\bin one as described here or specify the OCI.dll location in the command line (for example, changing a desktop shortcut) as follows:

OracleMaestro.exe OCIDLL=<full_path_to_oci.dll>

Example:
OracleMaestro.exe OCIDLL=C:\oraclexe\app\oracle\product\10.2.0\server\BIN\oci.dll

I'm having problems connecting to Oracle with your software under Windows 7 x64.

Try the following solution:

Download a Win32 version of Oracle Instant Client Basic (not Basic Lite) from the Oracle website.
Extract all the files from the archive to a directory (e.g. C:\Oracle\incBin).
Create a directory (e.g. C:\Oracle\incTNS) and copy there your TNSNAMES.ORA.
Create a new environment variable TNS_ADMIN=C:\Oracle\incTNS.
Add the C:\Oracle\incBin directory to the system PATH.

Does Oracle Maestro support stored procedures and functions?

Yes. Most of database objects implemented in Oracle are supported by Oracle Maestro.

Are there any graphical tools for building and executing queries implemented?

Oracle Maestro provides two powerful tools which allow you either to edit query text directly with syntax highlighting and code completion or to build a query diagram visually selecting tables and fields, setting links between tables, etc.

What is the function of Generate Database Report? Does the report include data?

Generate Database Report Wizard allows you to print definitions of the database objects. To run the wizard, select the Tools | Generate Database Report main menu item. The wizard helps you to print all the database object or specify the Categories for printing according to the selected object type. The report does not include database data.

Is code completion implemented in the SQL Editor?

The Editor area is provided for working with the text of the query. For your convenience code completion is enabled. You can activate the completion list by pressing the Ctrl+Space key combination.

I cannot edit the SQL definition using the SQL tab? Why?

The reason is that you are trying to edit SQL definition within the SQL tab of the object editor. Bear in mind that this text is read-only. If you want to modify the object definition, use SQL Editor or SQL Script Editor tools.

What is the difference between Object Manager and Object Browser?

Both Object Manager and Object Browser are tools for operating on database objects designed as extensions of the Database Explorer. Oracle Maestro provides such operations as multiple selecting of objects (for copying, dropping, etc.) and the ability of using drag-and-drop operations between Object Manager, Object Browser and Database Explorer as well as between instances of the Object Manager or Object Browser. Unlike Object Manager Object Browser represents objects as a grid with according possibilities (sorting, grouping, and filtering).

Is it possible to execute more than one query using SQL Editor?

SQL Editor provides you with an ability to execute multiple queries separated by a statement delimiter from the same editor tab. Queries are executed in a separate thread, so all Oracle Maestro features remain available during the execution.
