Обсуждение: Running Postgres on CD - With Win32
Hi everybody! I was using Postgres for quite some time now without any problems. Now I'm facing some new challenge: Create a Read-Only Client out of a given Application and put it on CD/DVD. As the Application uses a PostgreSQL-DB (running on a FreeBSD-Server) I would like to at least keep the DB-Interface and use Postgres. The client-app, unfortunatly, is written for the .NET-Platform and doesn't run under mono (yet). So the CD would need to be run under Windows for the moment. I found some Threads discussion using a Knoppix-like approach to get Postgres running on a read-only medium but they were all concentrationg on linux. As far as I understand there is no way of turning WAL completely off (which would be ok for a CD-version as false writes cannot occur und thus cannot destroy the db-content). So then there are two possibilities: Send all writes to log-files to nirvana (like the good old BOFH used to do) or into a memdrive. Has anybody accomplished the task to run PostgreSQL from CD (even on Linux) and is willing to contribute some of his/her experiences? Any help is greatly appreciated. ...Dennis
If all you want is a client you should just be able to write it and it will connect to the server and work. The client does not need to write just the server.

TIP 5: don't forget to increase your free space map settings
Hi Peter!<br /><br /> Of course I don't want to just include a client. For that i would just use Npgsql and that's it. AndI wouldn't need a CD/DVD at all. No, I want to export some of the data stored in the (linux-)backend onto the DVD togetherwith a read-only-version of the client-app. And that application is a .NET-(Windows-)app. That would spare me theefford to create two different data-access-methods as I could just change the connection-string and would be through...Perfect solution, iff I can get postgres to run directly from that data-carrying DVD. And I don't want to installpostgres on any machine that DVD is run on. Most likely users won't have admin-rights or even priviledged user-rightswhen they use the created DVD.<br /><br /><br /> ...Dennis<br /><br /> Peter Childs schrieb: <blockquote cite="mida2de01dd0512310627v2eabae2m@mail.gmail.com"type="cite">If all you want is a client you should just be able to writeit and it will connect to the server and work.
