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 a full image copy of a 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, it acts as threshold for the number of active pages in the index space or partition. The default is 100.
• When displayed as output, the value is the number of active pages in the index space or partition, if object is indexspace and there's a recommendation for a full image copy. Otherwise, this value is NULL.
