VIPHST20 DD statement missing
At startup, a VIP agent builds a list of VSAM datasets for storing historical records. It does so by looking for a sequence of VIPHSTnn DD statements, starting with nn=00. It stops building that list when it encounters a gap in the sequence–when nn does not exist. The agent’s check for that non-existent DD statement is what causes the mainframe to issue the IEC130I message.
