Dictionary Type: Structure
Description: ST04 - Informix Monitor Main List
Description: ST04 - Informix Monitor Main List
Structure field list including key, data, relationships and ABAP select examples
INFST04 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 "ST04 - Informix Monitor Main List" 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_INFST04 TYPE INFST04.
The INFST04 table consists of various fields, each holding specific information or linking keys about ST04 - Informix Monitor Main List data available in SAP. These include SHMRES (Size of Resident Portion of Shared Memory (KB)), SHMVIRT (Size of Virtual Portion of Shared Memory (KB)), SHMMES (Message Portion of Shared Memory(KB)), PAGSIZE (Informix Page Size in Bytes).. 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. .
