In order to restart a job step that processes RACF®^® protected data sets, you must be authorized to access all RACF^® protected data sets that were open when the checkpoint was taken. In order to restart, all password-protected VSAM data sets that were open at checkpoint time must have the pointer to their password in the access method control block (ACB) when the checkpoint is taken, or the password must be known to the operator. For RACF^® protected data sets, the userid specified on the RESTART job statement must be authorized to access the data set.
