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 a REORG on a table- or indexspace 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:
    • If the ratio of the sum of INSERTs, UPDATEs, and DELETEs since the last REORG to the total number of rows or LOBs in the table space or partition, expressed as a percentage, is greater than this value, DSNACCOR recommends running REORG on the tablespace.
    • If the ratio of the sum of the number of index entries that were inserted and deleted since the last REORG to the total number of index entries in the index space or partition, expressed as a percentage, is greater than this value, DSNACCOR recommends running REORG on the indexspace.
    • The default is 20.
  • When displayed as output, the value is:
    • The ratio of the sum of INSERTs, UPDATEs, and DELETEs since the last REORG to the total number of rows or LOBs in the table space or partition, expressed as a percentage, if object is tablespace and there's a recommendation for REORG.
    • The ratio of the sum of INSERTs and DELETEs since the last REORG to the total number of index entries in the index space or partition, expressed as a percentage, if object is indexspace and there's a recommendation for REORG.
    • NULL in any other case.
