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 REORG on a tablespace 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 ratio of the number of imperfectly chunked LOBs to the total number of rows or LOBs in the table space or partition, expressed as a percentage. The default is 10.
• When displayed as output, the value is the ratio of the number of imperfectly chunked LOBs 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. Otherwise, this value is null.
