CompareData 64bit version

Information
2012-Dec-31 | Tags: databasesynchronization

Start64!New version! - CompareDatais a nativeWindows cross-dbms application that allows you to visually compare and synchronize data between two SQL databases using ODBC drivers. You can retrieve some/all data for a table/view from two databases and compare the data visually to see differences highlighted on the screen. You can also compare data of two sql queries and dbms metadata.

Features

  • Compare data between two tables/views of the same or different names
  • Compare columns having the same or different names and/or data types
  • Compare data of two sql queries
  • Synchronize table data at row level, table level or folder level
  • Compare data of a group of tables/queries or all tables with one command
  • Compare resultsets of any size.* See comparing large resultsets
  • Compare schema for two tables or a group of tables including: columns, indices, primary key, foreign keys, triggers and table permissions
  • Compare stored procedures/functions
  • Command line or internally schedule comparisons and data synchronization
  • Multi-threaded, multicore-ready design. Native 64-bit version is available.  See x64
  • Free for comparing table/view data. New evaluation period with each new release.

CompareData 64bit version



CompareData 64-bit Version

Starting with release 1.5.0 a native 64-bit version of CompareData is available for 64-bit Windows XP and above. You can download the 64-bit version of the application from the download page.

Requirements

The first time you run the 64-bit version of the application, an embedded Firebird repository is created, if not already created from a previous release, and the application attempts to use it as the application repository.

However, due to issues with the currently included Firebird 64-bit ODBC driver, the Firebird embedded repository can not be used with the 64-bit version of the application and you must host the application repository on a supported DBMS that has a compliant 64-bit ODBC driver such as MS SQL Server, Oracle, DB2, Informix IDS or SQL Anywhere.

Use the application repository wizard (Tools | Data Sources menu) to create the application repository on one of the repository supported DBMSs and set the newly created repository as the application repository.

Advantage

Using the 64-bit version of the application you have access to larger memory space. Whereas 32-bit applications are limited by architecture to 2 GB of memory, 64-bit applications are practically limited only by the amount of memory available on the machine.

CompareData 32-bit Version

You can also use CompareData 32-bit version on 64-bit Windows and side by side with the 64-bit version of the application. Note that both 32-bit and 64-bit version of the application share the same registry keys, except for data sources, workspace base items, and the main window position and size. You can use the command line -p option to create separate environments, if needed, if you want to have separate environments for the 32 and 64-bit version of the application.

If you use the same repository with the 32-bit and 64-bit version of the application, be aware that opening the same DBMS comparison in more than one instance of the application using the same repository login ID is not recommended since the application does not do concurrency checking on repository data for the same repository user. See Sharing Repository for more info.

ODBC Driver Platform

[Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

When running the application on 64-bit Windows you can use 32-bit drivers only with the 32-bit version of the application and 64-bit drivers only with the 64-bit version of the application. The DBMS you want to connect to can be running as either 32-bit or 64-bit version but the driver platform (32 or 64-bit) must match the application platform in order for you to use it in CompareData.

Typically, 64-bit ODBC drivers install both 64-bit and 32-bit version of the driver when you install the 64-bit driver on 64-bit Windows to allow you to use the "same" driver from 32-bit and 64-bit applications. For such drivers, the 64-bit version of the driver is installed to Windows System32 system folder whereas the 32-bit version of the driver is installed to Windows SysWOW64 system folder.

ODBC Administrator

On 64-bit Windows there are two versions of the ODBC Administrator Windows application for setting up ODBC data sources. The 32-bit version can only be used to set up ODBC data sources for installed 32-bit ODBC drivers, and the 64-bit version can only be used to set up ODBC data sources for installed 64-bit ODBC drivers.

You can access the 32-bit version of the ODBC Administrator application from the 32-bit version of CompareData (Tools menu or main toolbar) or by running odbcad32.exe from SysWOW64 system folder. Similarly you can access the 64-bit ODBC Administrator from the 64-bit version of CompareData or from 64-bit Windows Control Panel or by running odbcad32.exe from System32 system folder.

Distinguishing 32-bit and 64-bit ODBC Data Sources

All user 32-bit and 64-bit ODBC data sources are visible when setting up an application data source in either 32-bit or 64-bit version of an ODBC client application. This allows you to set up a user data source once for drivers that install both 32-bit and 64-bit version of the driver to the system folders when the 64-bit version of the driver is installed as described above in ODBC Driver Platform. The respective 32-bit or 64-bit version of the driver is loaded depending on the application platform since 32-bit applications use sysWOW64 system folder whereas 64-bit applications use System32 system folder.

For drivers that install to their own folders or use separate installs for the 32-bit and 64-bit version of the driver, the driver platform must match the application platform in order for an ODBC data source to be usable by a client application. To help avoid errors, you can include '32' or other descriptive text when naming a 32-bit ODBC data source to help you identify that it can not be used with a 64-bit application.
