SYSLIMITS_BASIC view

The SYSLIMITS_BASIC view contains information about limits. This view is built on the QSYS.SYSLIMTBL table along with other system information. It does not return information about the job that logged the limit. This view returns less information than the SYSLIMITS view, but it requires less authorization and typically performs significantly better.
