To address the first question -- "why does Rose take so long to start up?"
This issue usually occurs on machines that have anti-virus software installed and which scan each file as it is referenced. Rose is a highly componentized application. The act of scanning each component as it is loaded, **plus** each file that is referenced by the loaded file, is a major cause of Rose start-up delays, even on fast machines with a lot of memory. We know which files and file types are the major cause of Rose's slow start, but for obvious corporate liability considerations we no longer advise customers on how to tune their anti-virus software to achieve improved load times. Rose can load fairly quickly on systems for which the anti-virus software has been tuned. For example, I just started up Rose Enterprise for the first time today on my Dell CPx laptop. It took 27 seconds. I would expect the time to be shorter on a machine with a faster CPU. With regard to the second question, "why does Rose take up so much memory?". Rose's memory footprint is a function of: - How many Rose add-ins are running - The size and number of the controlled units that are loaded in memory. The footprint can be reduced by having active only the add-ins that are needed at a given point in time. The footprint also can be reduced by partitioning the Rose model into controlled units and loading into memory only the controlled units that are needed. Rose's Workspace feature was added a few releases ago specifically to provide a convenient way for a user to define sets of essential controlled units and reload the pertinent set at the start of a new work session. Another cause of high memory usage is use of certain Rose frameworks, in particular the Java frameworks that ship with Rose. These things are big! More experienced Rose Java users do not start with the frameworks. Rather, they will simply reverse engineer from rt.jar or from j2ee.jar the framework classes that they really need for their modeling. ******************************************************** R a t i o n a l the software development company(tm) Todd Dunnavant Technical Lead, South Texas District Office Phone #: (281) 431-8751 Fax Phone #: (281) 431-8791 E-mail address: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Rational's Mission: "To ensure the success of Customers who depend on software development and deployment." ******************************************************** -----Original Message----- From: Jiri Svacina [mailto:[EMAIL PROTECTED]] Sent: Saturday, October 13, 2001 7:23 AM To: [EMAIL PROTECTED] Subject: RE: (ROSE) RE: Rose startup time Well, may be the question should be: Why does Rose require so much memory? :) Jiri Svacina -----Puvodni zprava----- Od: Jonathan McClure [SMTP:[EMAIL PROTECTED]] Odeslano: 11. oijna 2001 18:24 Komu: 'Netherwood Paul'; [EMAIL PROTECTED] Poedmit: (ROSE) RE: Rose startup time Sounds like a paging problem.
