• The connect dialog is now able to list TNS service names in the combo box, even if an Oracle Instant Client is used. Therefore, you have to provide the location of a tnsnames.ora file in the TNS_ADMIN Windows environment variable.
  • As you may remember, the expandable section of the connect dialog shows the file path of the currently used Oracle Home. This information is now extended by a different [TNS_ADMIN] location, if defined using the TNS_ADMIN environment variable or the TNS_ADMIN registry entry. That path overrides the default location of the tnsnames.ora file in %oracle_home%\rdbms\admin.
  • Starting with Oracle 12c release 2, Oracle object names are no more restricted to a maximum of 30 characters. For Oracle 12c release 2 databases, the length check has been weakened to 128 characters.
  • The order of Hora’s sidebar icons has been consolidated with the order of the corresponding main menu items.

Version 12.1.7

  • Direct TCP/IP connectivity now supports Oracle 12c connect modes SYSBACKUP, SYSDG, SYSKM
  • Direct TCP/IP connectivity now supports OS authentication
  • N’nchar literal’  is now supported

Version 12.1.6

  • Direct TCP/IP connection now supports Oracle 12c authentication.

Version 12.1.5

  • A new menu item
    Schema | Create BYTE to CHAR semantics conversion script …
    helps you to change nls_length_semantics of existing columns from BYTE to CHAR semantics. That can be performed best before changing from single to multi-byte character set, e.g. as a pre-migration task to Oracle 12c.
  • The SQL scratchpad now shows a slightly different icon for files that are stored on a network drive.
  • For better performance, the Tables page now comes up with the most essential (identifying) columns only. A toggle switch “show all columns” forces the remaining columns to be shown as well.
  • Improved performance for tooltips shown in SQL editor window (Table comments.)
  • “Create table”, “Add column” and “column properties” dialogs now highlight most-often-used data types ‘NUMBER’, ‘VARCHAR2’ and ‘DATE’ in data type dropdown lists using a bold blue font.
  • A new set of buttons below data grids allow dataset navigation, including an info panel showing record index and count.
  • A new dialog “view comments wizard” allows you to selectively propagate table column comments to view column comments. That makes it much more easy to having column comments for views.
  • A new menu item “Show DDL” for table columns generates SQL for adding the appropriate column including single-column constraints and column comments.
  • For performance reasons, the column “Referenced constraints” has been removed from the tables | constraints grid. This information is still available as detail information for the currently selected constraint.

Version 12.1.4

  • Each filter row in DataContent grids now allows you to select an operator such as “=” from a drop-down menu, depending on the data type of the column.
  • New page Additional | Flashback archives for Oracle 11g and later
  • The SQL page shows root folders in red font if it is not found, for example when working offline. You do not have to confirm another message box for each non-existing folder any more.
  • In data content view, tooltip hints show a preview of the content of CLOB columns.
  • New search box on the PL/SQL page allows you to restrict the list of methods showing only items that contain the search string.
  • On ER Diagrammer, the “tidy up” button has been removed. The function is now called automatically each time an entity has been moved or resized.
  • ER diagrammer snaps entity shapes to grid on resize and move.
    Grid size can be configured.
  • For CLOB fields, both “create INSERT script” and “create UPDATE script” commands now pass VARCHAR2 chunks to dbms_lob instead of hexadecimal encoded strings. Besides that is better readable by human, it works independently from the character set of the database.

Version 12.1.3

  • Since version 12.1.1, the PL/SQL page allows you to navigate to another procedure or function implementation within the same package body by Ctrl-clicking a procedure call. Now we added two buttons ‘go back’ and ‘go forward’ to the tool bar that allow you to navigate back to the original editor position and vice versa.
  • Editor windows now supports SQL*Plus command EXEC
  • Both “Show DDL” context menu command for tables and Reverse DB generate an insert statement for spatial columns as defined in user_sdo_geom_metadata (bounding rectangle).
    Clear Schema menu item now deletes from user_sdo_geom_metadata.
  • New main menu item “Schema | Find VARCHAR2 columns with long BYTE length …” searches for VARCHAR2 columns that may cause problems when converting to a multi-byte character set such as UTF8:
    • Because the length exceeds 4000 bytes
    • Because columns using BYTE semantics will not fit the column length defined in bytes.

Use this dialog to check long VARCHAR2 columns before you migrate your database to a multi-byte character set such as UTF8.

  • Hora’s settings dialog allows you to define one or two startup windows. Some minor differences between window names and name order used in the dropdown lists of the settings dialog now have been reconciled with the captions and menu item sequence used in Hora’s toolbar. Please re-check your startup windows setting, because under some circumstances the stored index may now refer to another startup window.
  • When the build-in direct TCP/IP connection is used, you now have another option for entering the database connect string using service name:


This is an alternative to the existing syntax

Oracle 12c database requires a connection by service name.
For connection to Oracle11g or prior databases by SID, you can still use any of


  • In both data content grid and sql query resultset views, all cell texts are now aligned to the top. In the past, only memo fields, that are capable to display multi-line text, had been aligned to the top, whereas all single-line controls had been vertically centered.
  • Besides tables and views, the data content browser now also shows local synonyms for tables and views.
  • The expandable section in the bottom of the connect dialog now allows you to enter an initialization script name. It is executed automatically each time after connect. You can use SQL and PL/SQL commands.
  • On the tables | columns page, all columns on band “column usage in WHERE predicates” have been moved over to the “statictics” tab. The band “column statistics”, has been removed from the columns tab, since the information is already shown on the statistics tab. This eliminates duplicate information and speeds up performance on the columns.

Version 12.1.2

  • DB Compare now generates UPDATE scripts that use ALTER TABLE commands instead of re-creating the table with changed structure.
  • DB Compare’s overview now shows an “Update Action” instead of the former “object change status”. This action describes how to consolidate the DB schemes rather than pointing out the difference between them.
  • A new checkbox option on Reverse/DB now allows you to check/uncheck whether CREATE TABLESPACE commands will be created.
  • Compile and Refresh menu items on Hora’s Materialized View page now have been enabled for multi-select.
  • Hora’s “Clear Schema” main menu item now truncates temporary tables before dropping to prevent ORA-14452 error.
  • The Reverse/DB tool now generates Oracle Contexts implemented by the DB schema, if the user has been granted select privileges on DBA_CONTEXT, granted by HORA_USER role, maybe.
  • Reverse/DB now orders the generation of views, materialized views, procedures, functions and packages by object dependency. As a result, there may be multiple sections for each object type, one for each level of dependency. By unchecking an option, you can get back to alphabetic order as before.
  • Scheduler jobs are now supported by Hora’s “show DDL” command, Reverse DB Engineer and DB Compare tool.
  • Support for Windows 10 Anniversary Update has been added. CodeMeter 6.30d runtime makes sure license are repaired, since the Anniversary update is actually a reinstallation of the operating system.

Version 12.1.1

  • On both PL/SQL and Tables | Triggers views, you can see red bullets in the gutter area for each error position. We added a view bar to the right of the editor window that visualizes the relative error positions within the source text by red markers. The part of source code currently visible in the editor is indicated by a gray bar that moves while scrolling the editor.
  • New page Database | ACLs for managing access control lists (ACLs).
  • In all editor windows, you can now use Shift+TAB as a shortcut to the block indent command (button and menu item).
  • On PL/SQL page, you can navigate to another procedure or function implementation within the same package body by Ctrl-clicking a procedure call.
  • Added new column “NLS length semantics” to the PLSQL overview page.
  • Added “PL/SQL object settings” band to the Types overview grid including “NLS length semantics” column and other columns known from PL/SQL page.
  • Added context menu items to DB-Compare’s object list for printing and Excel export.
  • Reverse/DDL now generates NLS_LENGTH_SEMANTICS setting.
  • DB Compare’s experimental update script now contains only changes to objects that are selected using the check box next to the object name.
  • CodeMeter 6.30b runtime. See wibu.com for change log.
  • Reverse/DDL now includes Java source.
  • Improved display of bullets to distinguish public from private methods on PL/SQL page.

Version 12.1.0

  • Now you can borrow/return a network license seat on your client. For a limited time, it allows you to use KeepTool offline. Therefore, either run “License Manager – Borrowing” from the Windows start menu, or “Help|License Management|License Manager / Borrowing” from Hora’s main menu. Options for borrowing can be configured on the license server using CodeMeter WebAdmin.
    Please don’t forget to update your network license server to make sure it runs CodeMeter 6.20a or newer.
  • The modal dialog for creating and changing views now shows a toolbar with operations that had been available on the editor’s context menu only.
  • The source code window on the PL/SQL page now shows a red bullet near erroneous source code lines.
  • Main menu item “Help | License info“ now shows output captured from CodeMeter cmu32.exe utility.
  • On Oracle 10g database or later, the “resize datafile” dialog suggests purging the tablespace’s recycle bin before downsizing a data file.
  • The “synonym owner” dropdown list on the “create synonym” dialog now uses bold fonts for owners of existing synonyms or grants.
  • Added query builder and SQL*Plus execution buttons to separate SQL editor HEdit.exe. These actions formerly have been available as context menu items only.
  • Both DB object browser window and column selection dialog (that comes up for example when using the “Selected object | expand …” menu items) now use blue font for mandatory columns.
  • Tooltip hints for table comment and column description in DB object browser.
  • Dockable windows remember “undocked” status for next start.
  • Added a menu for “check all and “uncheck all” combo boxes to the confirmation dialog for operations on a multi-selection, such as “Drop user”.
  • A new Findpanel has been added to both Data content and SQL resultset grids. When memory mode is active, all occurrences of the search text in any column are highlighted in the grid view.
  • Hora’s now SQL remembers the :parameter and &macro values for the database connection string beyond end of session.
  • There is a new option on the data content tab for including the ORA_ROWSCN pseudo column in the SELECT statement that populates the data grid. Oracle doesn’t allow this pseudo column to be used in conjunction with tables having a virtual private database policy. The new option lets you decide to select ORA_ROWSCN pseudo column always, never, or automatically if the table has no policy function. Whereas the latter choice is the most convenient, the other options perform better.
    Remember, both ROWID and ORA_ROWSCN columns are selected but invisible by default and can be showed using the column selection tool in the upper left of the data grid.
    • On Tables page, menu “Copy to clipboard|XXX statement”
    • In editor windows, menu “Selected object, expand XXX statement”
    • In editor windows, DB object browser, drag-drop target menu, XXX statement
      now share the same column pre-selection dialog and SQL generation engine.
      For INSERT statements, there is a new option “default values” that adds rather default values or NULL values (for optional columns) to the VALUES clause than formal “:” variables, that are still used for mandatory non-default columns..
  • For the “execute script” command, the editor component now positions the input cursor to the SQL error position similar to “execute query”.
  • Information shown in tooltip hints for data grid headers, DB object browser and SELECT/INSERT/UPDATE SQL generators is now cached.

Version 12.0.3

  • A new option “Settings | SQL page | show active tooltips” allows you to disable context sensitive tooltips, especially when using a slow database connection.
  • Active tooltips on SQL page are cached now for better performance
  • A new toggle switch “Sample binds” on the session page allows you to include sample binds on demand only.
  • Excel export now allows you to change file name. Export directory is stored as default for next call for both connection and database.

Version 12.0.2

  • Tablespaces using more than 95% [99%] of the maximum auto extensible space are highlighted yellow [red].
  • New skins Office2016Colorful and Office2016Dark.
  • Support for Materialized View Refresh groups
  • Connect dialog now allows you to use PNG and GIF images besides BMP and JPG. Improved image alignment when displayed in form header.
  • On the Schema | Spatial Columns page, the menu item “Comment spatial index table” has been replaced by “Comment all spatial index support tables …”. It batch-creates comments for all MDRT% and MDXT% tables in the current schema that are created implicitly by Oracle for spatial index support.
  • Wibu 6.20 license management runtime. It is recommended (but not required) to update the network license server as well.
  • Incremental search in data content filter box now can be disabled by settings.

Version 12.0.1

  • Several Materialized View refresh options can be changed now, including the new Oracle 12c “out of place refresh” option.
  • Colors for tagging DB connections now can be configured in the settings dialog.
  • A new Button “Delete saved passwords” on the “Settings | Startup window” page allows you to delete all (encrypted) passwords from ktprojects.xml file that have been saved by the connect dialog.
  • You can add a Boolean registry entry HKLM\Software\KeepTool\12\DontSavePasswords to prevent the user from saving passwords in the connect dialog. Double-click registry file DontSavePasswords.re (or DontSavePasswordsWow6432.reg on 32-bit subsystem) to import an appropriate registry key.
