Starting VTAM to use Db2

You do not need to code any special VTAM® start options to use Db2, but you can tailor start option values for Db2 communications.

About this task

You must start VTAM before starting DDF.

Two VTAM libraries must contain definitions for Db2:

  • SYS1.VTAMLST contains the definitions that define Db2 as a VTAM application.
  • SYS1.VTAMLIB contains mode table definitions used by DDF. This must be an APF-authorized library, or in a concatenation of APF-authorized libraries.

Procedure

To enable VTAM to use Db2:

You can use the following VTAM command, assuming that the member DB2APPLS contains definitions for Db2: 
V NET,ACT,ID=DB2APPLS
