DB2QBGB 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 "DB2/390: Group Buffer Pool Parameters" 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_DB2QBGB TYPE DB2QBGB.

The DB2QBGB table consists of various fields, each holding specific information or linking keys about DB2/390: Group Buffer Pool Parameters data available in SAP. These include QBGBGR1 (The current directory entry per data entry ratio), QBGBGR2 (The pending directory entry per data entry ratio), QBGBGCT (Class castout threshold (%)), QBGBGGT (Group buffer pool castout threshold (%))..
