Firebird Embedded and LibreOffice is the killer combination to scale from a single file application to a client/server approach

Leave a comment

Quote of the day is via this thread on Firebird Java Group :

It would be good if Jaybird 2.3 could be used with embedded and
LibreOffice because the feature set in Firebird is obviously much, much greater
than HSQL or the proposed SQLite replacement.

The ability to create a zeroconf, transportable data file is of interest to me
(along with using iReport to generate printouts from that file).

OT: Personally I think that Jaybird / Firebird / Firebird embedded is the way to
go for LibreOffice instead of the very limited SQLite. The ability to upscale
from a single file application to a client/server one is a killer.

Update:Firebird Driver and Embedded version merged into LibreOffice git master

Firebird on Large Big Iron servers : 512G-2TB of ram 100.000 concurrent users

Leave a comment

Nikolay Samofatov wrote about his Large Iron production systems that he maintains :

We run Firebird to power larger systems (for 12 government agencies and 3 banks).

It has approximately 100000 end users multiplexed through 2500 (max) pooled connections.

Here is the snapshot of nearly idle system at night:

top - 03:20:39 up 10 days,  8:39,  7 users,  load average: 2.08, 1.87, 2.15
Tasks: 1732 total,   1 running, 1730 sleeping,   1 stopped,   0 zombie
Cpu(s): 11.9%us,  4.0%sy,  0.0%ni, 83.5%id,  0.0%wa,  0.0%hi,  0.6%si,  0.0%st
Mem: 529177288k total, 378587600k used, 150589688k free, 761532k buffers Swap: 1073741816k total, 130612k used, 1073611204k free, 333281232k cached

[root  mvv bin]# ps aux | grep -c rdb_inet_server
719

Database is on a small FusionIO drive:

mount:
/dev/fiob on /mnt/db type ext2 (rw,noatime)
df -h:
/dev/fiob             587G  423G  135G  76% /mnt/db

Also later he mentions that he uses 2TB of RAM machines

Chipsets that can handle 2 TB of RAM and 8 CPU sockets (<=80 cores, <=160 threads) are the largest “commodity” type hardware available now. These are the largest systems we worked on. 8 GB of lock manager space per database should be just enough for them. With the allocation error check in place we’ll have this problem solved for the next year or two until larger systems become common.

Firebird .Net Provider Improved “weekly” builds

Leave a comment

I’ve improved the http://netprovider.cincura.net/ . It’s now returning
version build from latest SVN sources (so it’s actually snapshot
builds now). Again could be unstable, not a good idea to put it to
production.

PS: It’s reading the build from my internal CI server, that is really
old and really not very powerful. Please try not to push it to the
limit.

New Book On Qt And Firebird Database Available In EPUB Format

Leave a comment

Logikal Solutions is proud to announce “The Minimum You Need to Know About Qt and Databases” has been released in EPUB format as part of “The Minimum You Need to Know” book series. Currently it is available at Barnes & Nobel as well as Kobo. It should also be available shortly at the Sony eBook store.

Barnes & Nobel

Kobo

This book shows the nitty-gritty of developing with Qt using PostgreSQL, Firebird, and SQLite databases. It also shows the developer how to create BOTH console and GUI Qt applications. Readers are shown how to do development with Qt Designer, Qt Creator, QDevelop, Monkey Studio, and Eclipse under KUbuntu. Like most of the titles in this series this book attempts to teach by repeatedly developing the same application with each new tool set so developers who understand one or only “some” of a given tool set can quickly come up to speed by looking at the differences each tool forces on the application. 

Qt is an amazing application framework currently owned and supported by Nokia. While there are many books available discussing various aspects of the GUI, most give at most a single chapter to database access. This book is designed to cover that topic in depth. The vast majority of applications written today will need to communicate with a database in some fashion, even if it is just to store user entered data locally. Currently there are no books on the market providing any significant quantity of information about how to do it are more importantly just how different your application will be for each database engine.

“The Minimum You Need to Know” is an award winning technical book series written by Roland Hughes and published by Logikal Solutions. Please visit The Minimum You Need to Know for information about other titles in this technical book series.
