Data can be processed through ES/1 it into a “databox” that holds a compressed form of records. Acquire for z/OS can read databox records as if it were the original SMF records. To tell Acquire to do this, include a parameter of SOURCE=D. The default is SOURCE=S, meaning to expect regular SMF data. No run-time JCL changes are needed as Acquire for z/OS uses the same DDNAME of SMFDATA no matter what you choose to do.
If you plan to use this facility you must concatenate the ES/1 load library after the Acquire for z/OS load library so that the ES/1 module CPESUB00 is available to load.
Note that anywhere in this section that refers to reading SMF data also implies “or data from an ES/1 databox”.
