DB2_KPI_QBST SAP (bufferpool activity data) Structure details
Description: bufferpool activity data
Structure field list including key, data, relationships and ABAP select examples
DB2_KPI_QBST 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 "bufferpool activity data" 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_DB2_KPI_QBST TYPE DB2_KPI_QBST.
The DB2_KPI_QBST table consists of various fields, each holding specific information or linking keys about bufferpool activity data data available in SAP. These include QBSTBPNM (DB2 buffer pool name), QBSTVPL (Number of buffers allocated for virtual buffer pool), QBSTGET (Number of get page requests (conditional and unconditional)), RANDHITR (Random hit ratio).. 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. .
