So, for CS one will need to install/run fblistener.exe and don't care about anything else. For SS/SC one will need to install/run firebird.exe and setup the config properly (SS by default). The installer will just ask about SharedDatabase/SharedCache (or about CS/SC/SS - although these terms become outdated with v3) and figure out what binary should be installed and whether it's needed to change the config. No eight possible options anymore. Not much harder to understand than for v2.5. Almost same for POSIX and Windows. If SC is going to be deprecated (at least at the installer level), then setup becomes even easier.

[Firebird-devel] fb3 access modes under windows
I was playing with the different access configurations for FB 3 in firebird.conf. (with Alpha2) With this configuration: SharedCache = true SharedDatabase = true and server installed as SS. (ie, instsvc i ) Access via localhost is denied: C:\Program Files\Firebird\Firebird_3_0isql -user SYSDBA -password masterkey localhost:employee Statement failed, SQLSTATE = 28000 Your user name and password are not defined. Ask your database administrator to set up a Firebird login. Direct access produces this error: C:\Program Files\Firebird\Firebird_3_0isql -user SYSDBA -password masterkey employee Statement failed, SQLSTATE = 0A000 feature is not supported -SharedDatabase and SharedCache settings cannot be both enabled at once I got the same results after changing instsvc to use i -c (ie run as CS) There seems to be two separate issues here: - The error thrown when accessing host:db seems erroneous. un/pw are defined and correct. - direct access throws 'feature not supported' despite the fact that the combination is clearly documented as legal in firebird.conf. The reason I was trying this was to try and answer Pavel's question - how do you run SuperClassic under FB3 on Windows? AFAICT it is not possible. I don't mind - SuperClassic seems to share the worst features of SuperServer and ClassicServer, and we should officially deprecate in FB3 (imo.) But the questions will be asked - how can we run SC under FB3? and does it make any sense?

Re: [Firebird-devel] fb3 access modes under windows

Really ? :) I don't mind - SuperClassic seems to share the worst features of SuperServer and ClassicServer, and we should officially deprecate in FB3 (imo.) Probably. But the questions will be asked - how can we run SC under FB3? Isn't it was explained when shared page cache was committed ? Also, it was clearly stated that possible run modes could be changed before release, IIRC. Well, to run SuperClassic you should: a) set in firebird.conf SharedDatabase = true SharedCache = false and b) run listener in threaded mode firebird -m [-a] and does it make any sense? It depends on what is a sense :) As in v2.5 SC : - consumes less resources than CS - is able to utilize all CPUs\cores - allows another processes to access database - have same stability behaviour as SS Regards, Vlad -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.

Possibly - but I don't think it has been fully documented since then. I'm just an ordinary clueless user who blunders about, reading as little documentation as possible, trying whatever combination that works. :-) Well, to run SuperClassic you should: a) set in firebird.conf SharedDatabase = true SharedCache = false and b) run listener in threaded mode firebird -m [-a] and does it make any sense? Yes, that works. One of the problems here is that the -m switch needs to be documented better (there are other problems with the -m switch, but documentation is the biggest.) Basically this: instsvc i installs firebird to run with the -m switch and this: instsvc i -c installs it to run without the -m switch. Subsequent behaviour then depends on the configuration of firebird.conf, but there is no mention in firebird.conf as to how the two SharedN switches interact with -m So this line # SharedCache SharedDatabase Mode # falsetrueClassic with shared access // traditional CS/SC is entirely dependant upon the -m switch, or lack of it to launch either CS or SC. I guess what we really need is to document in firebird.conf how the -m switch affects the other two settings. There would seem to be a total of eight combinations. Perhaps we need something like this: # SharedCache SharedDatabase -m Mode # false false - CS single attach only # false false * # false true- Classic with shared access # false true* SuperClassic with shared access # truefalse - ? # truefalse * Super with exclusive access # truetrue- Super with shared access - illegal in A2 :-) # truetrue* Super with shared access - also illegal Paul -- Paul Reeves http://www.ibphoenix.com Supporting users of Firebird -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.
