Structure field list including key, data, relationships and ABAP select examples

DB2QDBP is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Buffer Manager Dynamic Pool Attributes" Information within sap ABAP programs.

This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately.

i.e. DATA: wa_DB2QDBP TYPE DB2QDBP.

The DB2QDBP table consists of various fields, each holding specific information or linking keys about Buffer Manager Dynamic Pool Attributes data available in SAP. These include QDBPVPSZ (The size of the virtual buffer pool), QDBPVPSH (The sequential steal threshold for the virtual buffer pool), QDBPDWQT (The deferred write threshold for the virtual buffer pool), QDBPVDQT (The vertical deferred write threshold for the virtual BP).. See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
