SMF "Lone" Writer Records

"Lone" writer records are SMF type 6 output writer records that are associated with no other SMF record types when processed by MICS.

These SYSOUT records are usually assigned overhead account numbers if written to the BATSPL file because none of the conventional sources of account data are available with the exception of SMF type 6 output writer records for IP PrintWay.
"Lone" writer records are characterized by BATSPL observations with a SPLMASK of '...W..' where:
...
indicates the absence of execution records
W
indicates the presence of one or more SMF type 6 output writer records
.
indicates the absence of an SMF type 26 purge record
.
indicates the absence of the Job Account Derivation Hold (BATSFH) file
"Lone" writer records may be "late" SYSOUT or NJE SYSOUT. They can also represent the partial printing of output from a non-execution job (for example TYPRUN=SCAN or a pre-execution JCL error). It is impossible to tell which until the SMF type 26 purge record is generated.
The most notable thing about "lone" writer records is that the "lone" status is temporary. Eventually, the other SYSOUT data sets for the job will be printed or purged. You should code an SPLLIMIT statement in prefix.MICS.PARMS(SMFOPS) to delay the writing of "lone" SYSOUT records until the purge record is encountered. The SPLLIMIT statement is fully discussed in the SPLLIMIT section.
