DFS2578I ddname OPEN ERROR

Explanation

Program DBFDBFM0 was unable to open the DCB for this data set. Possible causes are:
  • There is a missing DD statement.
  • The JCL is incorrect.
  • A hardware error exists.

System action

Only one MSDB checkpoint is used if an MSDB checkpoint data set cannot be opened. No MSDB checkpoint is taken if both data sets cannot be opened. The DUMP facility of the MSDBs is canceled if the memory dump data set cannot be opened.

Programmer response

Make sure that a DD statement is present and that its specifications are correct. If a hardware failure is indicated, rerun the job.
