727.0. "Info needed on PROGRESS " by ODIXIE::GAYNOR () Thu Aug 30 1990 20:16

    Does anyone have any updated info on PROGRESS??  I have a customer who
    will be using PROGRESS as a tool to convert an ancient PRIME
    application and platform to a DEC platform, and I'm looking for any
    known kinks in converting something of this magnatude..ie.  PROGRESS's
    ability to support large amounts of data - how well it
    receives/transports data thru the gateway to RDB.  Are there any tools
    such as RDBEXPERT/TRACE for later tuning etc.
    
    Any help would be greatly appreciated!
    
    Thanks

727.1Use Rdbexpert and DectraceTRCO01::MCMULLENThu Aug 30 1990 20:3913
    Coreen,
    
    You can still use Rdbexpert and DECtrace to help design the physical
    database. There is no connection to the application tool required
    for the database tuning. Does PROGRESS produce compiled/interactive SQL that
    you can read. If so it will help to have this transaction information
    for the initial database design (one of the inputs to Rdbexpert).
    
    I am not familiar with PROGRESS, but if you can insert calls to
    DECtrace within the application, then you can also use DECtrace
    to collect specific application metrics.

727.2That's a help!ODIXIE::GAYNORThu Aug 30 1990 20:566
    Thanks for the info!  I'm not too experienced with Rdbexpert or
    Rdbtrace - I'll be checking into them more before next week.
    
    Thanks again

    Coreen,
    
    First, I assume it is a redevelopment and not a conversion. Conversion
    implies that part of the existing code is automatically converted.
    If it is a total rewrite, then it is a redevelopment and should
    include a review of its functionality if possible. You don't want
    to move the same mis-functions across.
    
    I would check with the PROGRESS people and some reference sites.
    PROGRESS is implemented in a Client/Server model so it is important
    to determine who is doing the reads and writes; The user process?
    a detached job? and spawned (shades of Ingres) job? You could run
    into some interesting system configuration challenges.
    
    We have a copy of the software at our office so I'll see if there
    is anything in it which will help. One piece of advice is to determine
    how much on the hook DEC is for performance and ensure the appropriate
    3rd parties (e.g. PROGRESS) are also on the hook if it doesn't run.
