What is the maximum value of Maximum Servers (-Mn) parameter? Documentation (V9 through V11.5) says the max is 512 but in fact a database can be started with a higher value. Progress Explorer, of course, trusts in the documentation like it does for the -maxport value: http://knowledgebase.progress.com/articles/Article/P123130 According the tests on Windows the limit is applied to the sum of -Mn and -n and this sum should be less than 32765 (=32K-3). For example, I was able to start db with: proserve sports -Mn 32764 -n 1 proserve sports -Mn 32763 -n 2 but I got the error "OpenEdge Database Server/Broker has stopped working" with any higher values. Maximum Servers per Broker (-Mpb) can be set to the any value (even higher than the -Mn) but the message # 12820 reports it as a signed short integer. In other words the -Mpb was intended to be less than 32768. The message # 12820 was introduced in V10.1 where it replaced the message 5647: Maximum Servers Per Broker (-Mpb): %i . (5647) Maximum Servers Per Broker (-Mpb): %d . (12820) I guess some changes in this area were done exactly in Progress V10.1 but I failed to find the "footprints" of these changes in documentation or in Progress knowledgebase. The maximum server port (-maxport) must be between 1025 and 65535 . (5652) The minimum server port (-minport) must be between 1025 and 65535 . (5653) Obviously the -Mpb should not exceed -maxport minus -minport. The customer of ours is starting a bit less than 500 remote client servers per a database and we are not planning to increase this number. But in case of any troubles with remote connections we would like to be able to restart a login broker without restarting a database itself. That is why we need to start a database with the -Mn that is at least twice as higher than the real -Mpb (to have the spare slots in the -Mn table), let's say the -Mn 1024. It would be nice to get a "benediction" from the official source. ;-)
