Documentation

Definition

Beginning with DB2 V7.1, SAP utilizes a stored procedure named DSNACCOR which recommends running a utility based upon data in the real-time statistic tables. The recommendation for updating statistics of a table- or indexspace by running RUNSTATS is based on a complex calculation, which is detailed in DB2 UDB for OS/390 and z/OS V7 Utility Guide and Reference . This is one of the values that is used in the calculation.

It is an input and output parameter of type INTEGER:

  • When used for input:
    • The value acts as threshold for the number of mass deletes from a table space or partition since the last REORG or LOAD REPLACE, in case the object is a tablespace.
    • The value acts as threshold for the number of mass deletes from an index space or partition since the last REORG, REBUILD INDEX, or LOAD REPLACE , in case the object is a indexspace.
    • The default is 0.
  • When displayed as output, the value is:
    • The number of mass deletes from the table space or partition since the last REORG or LOAD REPLACE, if object is tablespace and there's a recommendation for RUNSTATS.
    • The ratio of the number of mass deletes from the index space or partition since the last REORG, REBUILD INDEX, or LOAD REPLACE, if object is indexspace and there's a recommendation for RUNSTATS.
    • NULL in any other case.
