When running the ACF2 reports, how do I determine what SMF files should be used?

Answer:  

When running the ACF2 reports the RECxxxx ddnames should point to appropriate SMF files that were active for the time that is being reported on.

When running ACF2 reports the SMF files must have ddnames beginning with the characters REC as in the following example:

//RECMAN1 DD DSN=SYS1.MAN1,DISP=SHR
//RECMAN2 DD DSN=SYS1.MAN2,DISP=SHR

In the supplied JCL, these files provide input for ACF2 report programs. The RECxxxxx files are either VSAM or non-VSAM. RECxxxxx files cannot be concatenated. VSAM files are the currently active SYS1.MANx Datasets, non-VSAM files are backup files.

To determine the current SMF files that are active on the system the following operator command can be issued:

D SMF

Sample output:

         NAME       VOLSER  SIZE(BLKS)  %FULL  STATUS    
        P-SYS1.MAN1 MVSXX1      36000     0    ALTERNATE  
        S-SYS1.MAN2 MVSXX1      36000    46    ACTIVE     
        S-SYS1.MAN3 MVSXX1      36000     0    ALTERNATE

In this instance the RECMAN1 should point to SYS1.MAN2 - the only dataset with any data.
