Add Column of Configured Maximum number of jobs on Active Prestart Jobs

In the latest TRs, V7R4 TR11 in our case have been included some additional columns that also included the Peak in Use! It would be very usefull to also have an additional column with the configured Maximum number of jobs per PJ, so we could easily identify in which PJs, we are we approaching the limits!

    The configured Maximum Number of jobs per PJ is already available, but you have to combine two SQL services, and this is the power of SQL service, combine them so you can retrieve the information you want.

    Just expand the example for PRESTART_JOB_STATISTICS found at

    https://www.ibm.com/docs/en/i/7.4.0?topic=services-prestart-job-statistics-table-function
    to include the MAXIMUM_JOBS column.

    select PJ.PRESTART_JOB_NAME, case when cast(PJ.MAXIMUM_JOBS as varchar(6)) = '-1' then '*NOMAX' else cast(PJ.MAXIMUM_JOBS as varchar(6)) end as MAX_JOBS, case when PJ.MAXIMUM_JOBS <> -1 then PJ.MAXIMUM_JOBS - CURRENT_JOBS end as JOBS_LEFT, STAT.*

    from QSYS2.PRESTART_JOB_INFO PJ,

    lateral (select * from table (QSYS2.PRESTART_JOB_STATISTICS(PJ.SUBSYSTEM_DESCRIPTION, PJ.PRESTART_JOB_PROGRAM_LIBRARY, PJ.PRESTART_JOB_PROGRAM)

    )) as STAT where PJ.SUBSYSTEM_ACTIVE = 'YES' and PJ.SUBSYSTEM_DESCRIPTION = 'QUSRWRK';
