DB2QBAC SAP (Buffer Pool Statistics Data) Structure details
Description: Buffer Pool Statistics Data
Structure field list including key, data, relationships and ABAP select examples
DB2QBAC 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 Pool Statistics 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_DB2QBAC TYPE DB2QBAC.
The DB2QBAC table consists of various fields, each holding specific information or linking keys about Buffer Pool Statistics Data data available in SAP. These include QBACPID (Buffer pool ID), QBACGET (Number of Getpage Requests), QBACSWS (The number of times a buffer update occurs for the agent), QBACRIO (Number of synchronous read I/O operations).. 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. .
