[firebird-support] There are risks accessing a database with two servers?
Hello everybody: After reading in this article: http://www.firebirdfaq.org/faq3/ Alternatively, you can add a second server to do long running reports (OLAP) and keep Super Server for fast transactions (OLTP). it seems possible and desirable to have 2 Servers, one for long running reports (probably using Classic) and another for the other tasks (using SuperServer) Is that right? There are not risks of corrupting the database doing so? Thanks in advance. Walter. [Non-text portions of this message have been removed]

it seems possible and desirable to have 2 Servers, one for long running reports (probably using Classic) and another for the other tasks (using SuperServer) Is that right? Classic server can't open a database opened by superserver, because SS opens it exclusive mode. May be the article refer to two classic servers accessing the same db.

Re: [firebird-support] There are risks accessing a database with two servers?
I'm pretty sure that what the article means (although not clearly especified), is that you should have two firebird instances with 2 separated databases. These databases should be replicated from one (OLTP) to another (OLAP) in any way you think is best for your case.

My guess is it is talking about a two (or more) database setup: One is the OLTP database and the other its the OLAP / data warehouse database. The OLTP is used for the actual 'business' side of things, the OLAP for generating reports. The OLAP database is reloaded (or synchronized) regularly from the OLTP database, but might be slightly out of date. Mark

Ok, thanks, it is more clear now. Where I can find more information about OLAP and OLTP, some link you can recommend me? Greetings. Walter.

Re: [firebird-support] There are risks accessing a database with two servers?
Anyway, OLAP and OLTP are general database concepts, not only applied to Firebird. Wikipedia and other Google sources will give you enough informations to play with. If you want a more academic approach, you could look to this awesome book: http://www.amazon.com/Fundamentals-Database-Systems-Ramez-Elmasri/dp/0136086209 This is one is very good book to start if you want to have a plain database systems knowledge.
