Description:

When using the LOGSTREAM structures for SMF collection (instead of the SYS1.MAN datasets), can the TSSOERPT read the LOGSTREAM structures? If yes, what needs to be coded in the JCL?

Solution:

For z/OS 1.9 and above, SMF data may be sent to the LOGGER services controlling the writing of SMF data in the LOGSTREAM structures. SMF data will not be recorded in the usual SYS1.MANx data sets.

The RECxxxxx DD used to read the data has the format:

//RECxxxxx DD DSN=IFASMF.DATA.LOGSTRM,DISP=SHR,                              
// SUBSYS=(LOGR,IFASEXIT,subsys-options1,subsys-options2)  

Description of SUBSYS options-1 includes:

[FROM={({[yyyy/ddd][,hh:mm[:ss]]}) | OLDEST}]                                
[TO={({[yyyy/ddd][,hh:mm[:ss]]}) | YOUNGEST}]                                
[,DURATION=(nnnn,HOURS)]                                                     
[,VIEW={ACTIVE|ALL|INACTIVE}]                                                
[,GMT|LOCAL]  

The subsys-options1 parameters used by the IBM IFASEXIT are the same as those used by the IFBSEXIT. For information on the parameters for IFBSEXIT, see IBM's MVS Diagnosis: Tools and Service Aids.
