- Does Omega work with Windows XP?
Testing the front-end GUI (with the menu that launches the Omega modules) has revealed an issue with the minimise/maximise titlebar widgets - this can be worked around by using the classic interface theme or using the application compatability mechanism. See the XP SP2 support document available from the documentation page.
- Does Omega work with Windows Vista?
During this testing it was found that the Omega front-end and main modules worked correctly, although there were problems with the Pervasive.SQL 2000i and 9.x workgroup engines and client requesters due to the enhanced security mechanisms in Vista. Pervasive (now Actian) has added documentation to its website with solutions/workarounds, though they have only tested these thoroughly with Pervasive.SQL 9.5 and later due to their dropping of support for 8.x and earlier.
- Does Omega work with Windows 7?
Omega does work with Windows 7 - it has been tested in-house and is used by customer sites. Pervasive (now Actian) only supported Pervasive.SQL 10.3 and later with Windows 7 currently (October 2015) only maintains support for Pervasive.SQL11.x and 12.
- Does Omega work with Windows 8 or 8.1?
Omega has not been tested with Windows 8 or 8.1, and no sites are known to be using this combination as of October 2015. In theory Omega should run as well on Windows 8.x as on 7.
Does Omega work with Windows 10?
Omega has undergone limited testing with Windows 10 as of October 2015 and appears to work correctly.
- What is the difference between DATA\CONTROL\DDF and DATA\CONTROL\ODBC?
The DDF directory has always been used to hold the Crystal Reports data dictionaries. Older versions of Omega (particularly Omega for DOS v1.15 and earlier) have sub-directories containing dictionaries for each type of report (despatches, quotes, etc.), with each dictionary describing a limited number of tables. Later versions of Omega, and in particular Omega for Windows, contain a single set of dictionary files (FILE.DDF, FIELD.DDF and INDEX.DDF) used by all of the reports.
The ODBC directory contains a single set of dictionary files used for creating ODBC data sources. The dictionary is slightly different in that it does not locate the database files with a drive mapping (C:, O:, etc.) but locates them relative to the Omega root directory. The ODBC directory was introduced in later versions of Omega for Windows.
- Why won't my F8 search criteria work?
In the file selector F8 search window the search mechanism will ignore 0 or null-string criteria. So:
"Quantity > 0" will not work for an integer search,
"Quantity >= 1" will, and achieves the same thing.
Also remember that the search will only work on non-indexed fields if that field is being 'returned', i.e. it is visible or has been hard-coded as a field always present.
What do the function keys do?
The most common function key options are shown here.
What does 'duplicate key error' mean when reported by Omega?
Under normal circumstances you should not see this message. It means that Omega is trying to add a record to the database and the unique information in that record, e.g. the board number in a board record, already exists. If two people are trying to insert the same unique information at the same time this can cause the issue; a less likely cause is data corruption. The database engine is returning status 5 and this is an error that Omega recognizes as a duplication error. See here for more information on database status codes.
What does 'key value not found' mean when reported by Omega?
This message should never be seen unless there is a problem with the application or the database has been accidentally updated with incorrect values. It means that Omega is trying to load specific records from the database using search criteria, e.g. board number + customer code + revision level to load an exiting customer revision, and the record does not exist. See here for more information on database status codes.
Can I still upgrade Omega?
Support4Omega no longer offers an upgrade service for the Omega application (including upgrading Omega for DOS to Omega for Windows). The long period of time since the remaining Omega installations were last upgraded means that a lot of changes have been made to the database schema and this will affect a large number of reports that will need rebuilding and alteration. Along with the requirement for file conversions and re-training, it is no longer feasible with the limited resources available to attempt an update and not expect serious disruption. Omega application downloads should therefore only be done when the version is not changing, e.g. to recover a lost or damaged installation.
