On the iSeries/AS400, A CDRIVER is a Lawson IBMDB program written in “C Language” and runs on the System i platform.
Its primary use is to retrieve data from DB2 using Structured Query Language (SQL)/Call Level Interface (CLI) Application Program Interfaces (APIs).
Furthermore, Lawson Jobs are using CDRIVER. Each Lawson Job has its own CDRIVER per Data Area or Product Line. Its purpose is to run SQL commands to retrieve database records requested by the job connected to it. The job name will be automatically registered in the CDRIVER joblog and the job that is attached to it may change if REUSE is set to “ON” in the ladb.cfg.
