  ****************************************************************
  CHECK DATA SHRLEVEL CHANGE and CHECK LOB SHRLEVEL CHANGE
  currently do not reset any CHKP, ACHKP, or AUXW status even
  when there are no violations of referential or table check
  constraints, or inconsistencies between the base table space
  and the corresponding LOB or XML table space.  By design,
  CHECK utilities with SHRLEVEL CHANGE operate on shadow objects
  allowing updates to the original objects during execution and
  may not know if inconsistencies may have been introduced
  during the utility execution.  However, the likelihood of DML
  operations introducing inconsistencies during CHECK SHRLEVEL
  CHANGE is small, and outweigh the impact that a restrictive
  state has on data availability.
  

Problem conclusion

Temporary fix

Comments

• CHECK DATA and CHECK LOB utility code are modified to allow
  CHECK DATA SHRLEVEL CHANGE and CHECK LOB SHRLEVEL CHANGE to
  reset an existing CHECK-pending, auxiliary CHECK-pending,
  or auxiliary warning restrictive state if no inconsistencies
  are found. This new function is available starting with FL100
  of Db2 12 for z/OS.
