DB2QBSTT SAP (DB2 CL - Buffer manager statitics block) Structure details
Dictionary Type: Structure
Description: DB2 CL - Buffer manager statitics block
Description: DB2 CL - Buffer manager statitics block
Structure field list including key, data, relationships and ABAP select examples
DB2QBSTT 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 "DB2 CL - Buffer manager statitics block" 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_DB2QBSTT TYPE DB2QBSTT.
The DB2QBSTT table consists of various fields, each holding specific information or linking keys about DB2 CL - Buffer manager statitics block data available in SAP. These include QBSTBPNM (DB2 buffer pool name), QBSTPID (Field type numc, length 10, integer), QBSTGET (Number of get page requests (conditional and unconditional)), QBSTRIO (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. .
