SYS030/SYS040 DD Statements referenced by the Performance Monitor PMSMFEX extract were introduced at IDMS release 18.0 for Type 230 SMF records (SYS030) and SMF Type 4 records (SYS040).
At IDMS releases prior to r18.0, these records went to SYS020. Incidentally, if you left out a SYS020 DD statement in 17.0 and prior releases, you would get the IEC130I for SYS020.
Information on the new SYS030/SYS040 DD statements for PMSMFEX for 18.0 are in the CA IDMS Performance Monitor System Administration Guide, in the section titled:
Using SMF to Archive Statistics (z/OS only)
If not extracting SMF 230 or 4 records, then DD DUMMY on those statements can be used.
By the way, even if PMSMFEX is really not writing SMF type 4 or 30 records, it will attempt to open those DDNAMEs.
The DD Statements for SYS030 and SYS040 are as follows:
//SYS030 DD DSN=user.pmsmfex.outsmf30,DISP=(NEW,CATLG,DELETE),
//SYS040 DD DSN=user.pmsmfex.outsmf4,DISP=(NEW,CATLG,DELETE),
