Valentina Reports now support ODBC datasource!
This is great, because now Valentina Reports can work with data stored practically in any database format (MS Access, MS SQL, Oracle, Postgre SQL, mySQL, … ) and even XML.
In Valentina Studio improved datasource dialog to support ODBC.
In a Valentina ADK code, you should specify connection string in the VProject.MakeNewReport( inDataSource ), as the following: odbc://dsn=access,user=name,pass=123
Will be available in the 4.9b5 build or newer.
We have made two new x64 products on request of Valentina developers:
* VSDK x64 WIN
* VServer Embedded x64 Linux
As a part of the Omegabundle 2011 for REAL Studio campaign, I have published the article 10 Hottest Features of Valentina Office Server – which just like it sounds, lists the top 10 features I think are particularly of interest to businesses which need a high performance database and business reports server at the center of their business. This covers a number of advantages you gain based on the underlying technology of Valentina DB, plus also the inclusion of the business reports engine that is also included with Valentina Office Server.
We introduce OS X Preference Pane “ValentinaServers”.

Today one of user have asked if Valentina supports partial index. Answer is YES OF COURSE, you can easy create a partial index using Table Methods.
We introduce a new utility method Valentina.CopyCursorToNewTable(), which is able to save you hundreds of lines of advanced code in your ADK-based applications. This method added into major Valentina ADKs.
You can read detailed description of this new method here.
Index fragmentation can cause problems with query performance. Indexes therefore need to be occasionally rebuilt. Read the full article in the “Valentina Performance Guide” document.
PROBLEM IS:
Up to now (v4.7), a VServer on start searches for INI file in the own directory. Algorithm expects that only one INI file exists in the folder. And if few INI files present, then the first by alphabet is used.
Continue reading VServer now uses the name of executable as primary instead of ini file
There is a new property – LogFilesLocation for both server and local.
It defines a folder where the logs should be placed in.
Default folder is “./vlogs”
Now you should not synch vClient API calls – vClient do it self and you are free to access and operates with vClient’s remote objects from different threads similiangly.
In particular, vStudio operates with remote connections via multiple threads and it was a source of some glitches and unexpected errors especially with a long queries. Now there are no more errors like “EOF reached…” or “Broken packet received…” which were result of incorrect thread synch.
We have added to SQL Editor of Valentina Studio great new feature: now you can get much more rich output from an SQL command. And this output is separated into 4 tab panels at bottom of Editor.

Valentina is a perfect choice to work with a big data. It employs vertical storage approach. It means – each column has own virtual file to be stored in. Most of db vendors use a horizontal storage – it stores a table data in record-by-record manner.
There are some vertical storage advantages:
We are happy to introduce, in the release 4.5, the result of our 8 months efforts – Valentina Server 64 bit for 3 platforms (win, mac, linux)!
There is a new feature in Valentina Server – SNMP agent.
Currently we support only get() and get_next() SNMP requests for the following oids:
sysDescr(“1.3.6.1.2.1.1.1.0” )
sysUpTime(“1.3.6.1.2.1.1.3.0” )
Not much info but it makes a possibility to monitor vServer over SNMP.
For now, SNMP facilities are available only for Windows.
You should specify SNMP port in the server ini-file (default port is 161, 0 means turn off SNMP agent):
…
[SNMP]
Port_SNMP=161; SNMP port to listen by VServer.
; 0 – do not use a SNMP port.
…
You may set LogToSysLog variable to 1 (in the INI file or via vServer properties) to make vServer put log messages into the system log:
* Event log for Windows
* SysLog for Linux.
The default state of variable is off.
