InterSystems Caché provider for Laravel (ODBC)

Laracaché

Laracaché is an InterSystems Caché database driver package for Laravel. Laracaché is an extension of Illuminate/Database that uses the php-odbc extension to communicate with Caché. This package plays well with Eloquent.

Quick Installation

PHP >= 8 and Laravel >= 8

composer require jeandormehl/laracache

Environment variables

Modify your .env file to look similar to this. Windows users only need set DB_CONNECTION and DB_WIN_DSN variables. Unix users should set all other variables as seen below:

DB_CONNECTION=isc
DB_WIN_DSN=
DB_UNIX_DRIVER=/usr/lib/intersystems/odbc/bin/libcacheodbcur6435.so
DB_HOST=127.0.0.1
DB_PORT=1972
DB_DATABASE=LARAVEL
DB_USERNAME=_SYSTEM
DB_PASSWORD=SYS

Configuration

Publish a configuration file by running the following Artisan command.

php artisan vendor:publish --tag=isc

This will copy the configuration file to config/isc.php.

'isc' => [
    'driver'      => 'odbc',
    'win_dsn'     => env('DB_WIN_DSN', ''),         // windows users only
    'unix_driver' => env('DB_UNIX_DRIVER', ''),     // unix users only
    'host'        => env('DB_HOST', ''),
    'port'        => env('DB_PORT', 1972),
    'database'    => env('DB_DATABASE', ''),        // namespace
    'username'    => env('DB_USERNAME', '_SYSTEM'),
    'password'    => env('DB_PASSWORD', 'SYS'),
    'schema'      => env('DB_SCHEMA', 'SQLUser'),   // SQLUser is default, avoid changing if possible
    'options'     => [
        \PDO::ATTR_DEFAULT_FETCH_MODE => \PDO::FETCH_OBJ,
        'processor'                   => \Laracache\Cache\Query\Processors\Processor::class,
        'grammar'                     => [
            'query'  => \Laracache\Cache\Query\Grammars\Grammar::class,
            'schema' => \Laracache\Cache\Schema\Grammars\Grammar::class,
        ],
    ],
],

ODBC Drivers for Caché

You will need to ensure that you have the relevant ODBC drivers installed. For Linux distributions I recommended using the unixODBC driver, in specific, libcacheodbcur6435.so for 64-bit. If you have any trouble try to switch to libcacheodbcur64.so.

unixODBC

Download, untar and build the unixODBC package. This example uses version 2.3.7.

# get unixODBC
wget -q ftp://ftp.unixodbc.org/pub/unixODBC/unixODBC-2.3.7.tar.gz
untar the package
sudo tar -xzvf unixODBC-2.3.7.tar.gz
navigate to build file path, in this case, ~/unixODBC-2.3.7
cd ~/unixODBC-2.3.7
build the package - modify prefix, sysconfdir and doc location as needed
sudo -s <<EOF

./configure --prefix=/usr --sysconfdir=/etc 

&& make 

&& make install 

&& find doc -name "Makefile*" -delete 

&& chmod 644 doc/{lst,ProgrammerManual/Tutorial}/* 

&& install -v -m755 -d /usr/share/doc/unixODBC-2.3.7 

&& cp -v -R doc/* /usr/share/doc/unixODBC-2.3.7

EOF

php-odbc

Ensure php-odbc extension is installed. This example uses Apache & PHP 7.2.

sudo apt-get -y update
sudo apt-get -y install php-odbc
restart services
sudo service apache2 restart

sudo service php7.2-fpm restart

InterSystems ODBC Drivers

Download, untar and install. This example uses the 2018.1.0.184.0 build for Ubuntu 64bit. Find available drivers at this link:
InterSystems ODBC Drivers

# download drivers
wget -q https://github.com/jeandormehl/laracache/blob/master/ftp://ftp.intersys.com/pub/cache/odbc/2018/ODBC-2018.1.0.184.0-lnxubuntux64.tar.gz
create a directory to hold drivers and copy tar file to it
sudo mkdir -p /usr/lib/intersystems/odbc

sudo cp ODBC-2018.1.0.184.0-lnxubuntux64.tar.gz /usr/lib/intersystems/odbc
untar the file and run installer
sudo tar -xzvf /usr/lib/intersystems/odbc/ODBC-2018.1.0.184.0-lnxubuntux64.tar.gz

sudo /usr/lib/intersystems/odbc/ODBCinstall

/etc/odbc.ini

After completeing the above steps, you should have a file located in /etc called odbc.ini. Edit this file using vi or nano. It should look something like this:

[ODBC Data Sources]
cache=cache
[cache]

Driver                = /usr/lib/intersystems/odbc/bin/libcacheodbcur6435.so

Description           = InterSystems Cache ODBC Connection

Protocol              = TCP

Query Timeout         = 1

Static Cursors        = 0

Authentication Method = 0

Register and create symlink to the cursor.

# register
sudo odbcinst -i -s -f /etc/odbc.ini
create the symlink
sudo ln -s /usr/lib/x86_64-linux-gnu/libodbccr.so.2.0.0 /usr/lib/x86_64-linux-gnu/odbc/libodbccr.so

ODBC Installation and Validation on UNIX® Systems

For Windows, setup the ODBC data source in Administrative Tools and set the win_dns setting in the config file, isc.php to the name of your ODBC Data Source.
