IBM Discovery Library Adapter for z/OS output

IBM Z Resource Discovery Data Service (ZRD-DS) gathers mainframe data from IBM Discovery Library Adapter for z/OS (z/OS DLA) output (IdML books in XML format). For more information about installation and configuring z/OS DLA, see zDLA user guide.
Note: For the z/OS DLA version, at a minimum you need the PTF: UJ06027 To avoid all known problems, apply UJ06027 and all PTFs that are available since UJ06027. This includes currency fixes for z/OS and the discovered subsystems.
