Background documentation Number of physical writes of temporary pages Locate the document in its SAP Library structure

Number of physical writes of temporary pages: <count>

Explanation

When temporary data pages are generated to build (buffer) sets of results (in JOINS or ORDER BY statements, for example), the data cache is not large enough for the temporary pages, and they have to be displaced to the data area. However, these pages must be exported out of the data area again for the further processing of the SQL statement.

User Response

Find the statement that causes these large amounts of (buffer) results to be created, and check the access strategies for this statement.

Note

For information on creating optimized SQL statements, see Optimizer: SAP DB 7.4..
