RE: Parallel saves: Splitting a library also

Pretty diagram, and, possibly a high level overview of what may work.
However, it didn't explain:
1 - Omitting the large library from the *ALLUSR in the one control group.
2 - How to use object level on one library.

Perhaps I need to do this:
Create two lists with WRKLBRM
One list would be called ALLUSRLIB
This list would have two lines

Opt List Name Use Type
1 ALLUSRLIB *BKU *OBJ

It would look like this:
Use . . . . . . . . . : *BKU
List name . . . . . . . ALLUSRLIB
Seq Library Object Type Attribute Member Inc/Exc
10 *ALLUSR *ALL *ALL *ALL *ALL *INC
20 #MXJRN@R *ALL *ALL *ALL *ALL *EXC

The other list would look like:
Use . . . . . . . . . : *BKU
List name . . . . . . . MXJOURNALS
Seq Library Object Type Attribute Member Inc/Exc
10 #MXJRN@R *ALL *ALL *ALL *ALL *INC

Then in my control group I would replace the *ALLUSR line below:
Weekly Retain Save SWA
Backup List ASP Activity Object While Message Sync
Seq Items Type Device SMTWTFS Detail Active Queue ID

10 *EXIT *DFTACT
20 *EXIT *DFTACT
30 *SAVSECDTA *DFTACT *NO
40 *SAVCFG *DFTACT *NO
50 *ALLUSR *SYSBAS *DFTACT *OBJ *LIB *LIB *NONE
60 QRY* *SYSBAS *DFTACT *OBJ *LIB *LIB *NONE
70 *ALLDLO *DFTACT *NO *YES
80 *LINK *ALLAVL *DFTACT *YES *YES *LIB *NONE
90 *EXIT *DFTACT
100 *EXIT *DFTACT
110 *EXIT *DFTACT

with the name of my two lists.
...
40 *SAVCFG *DFTACT *NO
50 MXJOURNALS *OBJ *SYSBAS *DFTACT *OBJ *LIB *LIB *NONE
60 ALLUSRLIB *OBJ *SYSBAS *DFTACT *OBJ *LIB *LIB *NONE
70 QRY* *SYSBAS *DFTACT *OBJ *LIB *LIB *NONE
...

The question I have is what makes that MXJOURNALS list process the
individual objects within the library in parallel? Or does it?
