14 Dec Basic OpenEdge DB Tuning: -B / Cache
Posted at 14:57h
in Database tuning
Tuning an OpenEdge DB on basic level requires only a few parameters to be considered. The -B is the most valuable parameter. When set to 100 000 (one hundred throusand) the DB will use 100000 times the size of a DB block as a cache. Often enough the -B parameter is not set or much too small. See the -B documentation here ...

This article describes a strategy to migrate OpenEdge (Progress Software) applications, e.g. from CHAR UI to .NET UI, or classic OpenEdge UI to HTML5 UI. This method is known as 'Soft Migration', 'Step-by-Stop Migration' or 'Soft Transformation'. The description uses OF-1 as example, but it is not bound to OF-1, it can be used with all OpenEdge development systems. The earlier article about OpenEdge Hard Migration can be found here....

15 Jan Hard Migration – Copy, Paste and Change
Posted at 12:00h
in Migration
The hard migration is useful, when the goal is, to migrate an OpenEdge application the fastest way, let's say from ADM to HTML5 UI. The copy, paste and change approach keeps the work flow and logic of existing programs, so the migration risks are low.
This migration strategy is based on the unique structure of OF-1, where any source code is ABL. To program data fetching or handle user interactions - so called client logic or screen logic - you can use more or less the same code as is use in an ADM/2 or GUI Builder / Appbuilder....
