Note: The Recital Universal ODBC Driver is a 32 bit implementation, so is not listed in the 64 bit ODBC Data Source Administrator, which is the default administrator accessed from Control Panel | Administration Tools.

 +
So, to create and configure Recital ODBC datasources, you need to use the Window 32 bit ODBC Data Source Administrator or Recital's own  Recital Universal ODBC Manager (32-bit).

The Window 32 bit ODBC Data Source Administrator is %windir%\SysWOW64\odbcad32.exe.

Windows

Once installed, the Recital ODBC Driver appears in the list of drivers in the 'Windows ODBC Data Source Administrator', accessible from 'Control Panel | Administrative Tools'.


Odbc drivers.png


The installer also creates the 'Recital Southwind' datasource to access the Recital southwind database on the local machine.

To add a new datasource, click the Add button:


Odbc add.png


Select the Recital ODBC Driver from the list of drivers.

Then fill in the details as follows:


Field Description
DSN A unique name for the data source
Description A brief description for the data source. Clicking on the '…' button pops up an editor window.
Server The server node hostname or IP address. A Recital Database Server must be installed and running on the target server in order to connect.
User The login name for the remote server.

64 bit Windows

Note: The Recital Universal ODBC Driver is a 32 bit implementation, so is not listed in the 64 bit ODBC Data Source Administrator, which is the default administrator accessed from Control Panel | Administration Tools.

So, to create and configure Recital ODBC datasources, you need to use the Window 32 bit ODBC Data Source Administrator or Recital's own Recital Universal ODBC Manager (32-bit).

The Window 32 bit ODBC Data Source Administrator is %windir%\SysWOW64\odbcad32.exe. The Recital Universal ODBC Manager (32-bit) can be accessed from the Control Panel (icon view).

Linux / UNIX

To determine the location of the configuration files: 

# odbcinst -j

Will return output similar to the following: 

unixODBC 2.2.11
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
USER DATA SOURCES..: /root/.odbc.ini

The Recital Driver information can be seen in the 'odbcinst.ini' file: 

[Recital]
Description		= Recital ODBC Driver
Driver		= /opt/recital/drivers/libodbc_recital.so
Setup		= /opt/recital/drivers/libodbc_recital.so
FileUsage		= 1
UsageCount	= 1

The Recital installer also adds the following DSN to the system 'odbc.ini' file: 

[Recital ODBC test]
Driver	= Recital 
DATABASE	= ODBC:RECITAL:SERVERNAME=?;USERNAME=?;PASSWORD=?;DATABASE=odbc_test;

Additional datasources can be added by editing the 'odbc.ini' text file directly, using the following format: 

[<unique DSN>]
Description = <informative text>
Driver = Recital
Database = <URL>

Where the <URL> is in the following format: 

ODBC:RECITAL:SERVERNAME=<node>;USERNAME=<user>;PASSWORD=<password>;DATABASE=<database>;

or 

ODBC:RECITAL:SERVERNAME=<node>;USERNAME=<user>;PASSWORD=<password>;DIRECTORY=<directory>;

The following may also be included: 

CLIENTLOGGING=TRUE;CLIENTLOGFILE=<filename>;

For example 

[southwind]
Driver	= Recital
DATABASE	= ODBC:RECITAL:SERVERNAME=192.168.1.3;USERNAME=user;PASSWORD=password;DATABASE=southwind;CLIENTLOGGING=TRUE;CLIENTLOGFILE=trace.txt;

[dir_test]
Driver	= Recital
DATABASE	= ODBC:RECITAL:SERVERNAME=192.168.1.3;USERNAME=user;PASSWORD=password;DIRECTORY=/opt/recital/data/od1;

Notes

  • As an alternative to manually editing the files, the same format can be used to create template files for installation by odbcinst: 
$ odbcinst -i -s <-l|-h> -f template_file

Running 'odbcinst' with no parameters gives usage instructions.

  • The <node> can be the hostname or IP address. A '?' can be used to signify the local host.
  • Storing the user and password details in the DSN is optional and careful consideration should be given to security implications. A '?' can be used in place of the user and password for local host connections where the environment variable DB_LOCAL_LOGIN is set to true in the recital.conf file.
  • The DB_TMPDIR environment variable must be set to a valid writeable directory on the server.
  • To test that the ODBC Driver is successfully installed and configured, use the dbodbc test program in <recital>/examples/odbc: 
# make
# ./dbodbc
