What is the Lawson Database Service?

The Lawson Database Service (lads) manages connections to a Lawson-supported, third-party relational database management system (RDBMS).

When the Landmark system or an application need to access the database, the lads must acquire the correct type of lock on the data. The normal database locking approach is to establish a shared lock for Landmark data. In this scenario, many users with shared locks can access the same resource at the same time.

Some Landmark utilities, such as dbcopy or those for database reorganization, need exclusive access to the data area. If there are any shared locks on the data area, lads will obtain an exclusive lock when they are released. Once the utility has an exclusive lock on the resource, any future shared lock requests will be denied.

You can set the lads listening port and turn debugging on or off using the %LACFGDIR%\lads.cfg file. Configuring the Database Server
