| Field | Description |
|---|---|
| ASSOREAD | Associator read. The total number of Associator read I/Os that occurred during the Adabas session. |
| ASSOWRIT | Associator write. The total number of Associator write I/Os that occurred during the Adabas session. |
| DATAREAD | The total number of Adabas Data Storage read I/Os for the Adabas session. |
| DATAWRIT | The total number of Adabas Data Storage write I/Os for the Adabas session. |
| IOS | The total number of I/Os for the command processed; it is the sum of ASSOIO, DATAIO and WORKIO. |
| IOCOMP | Identifies the Adabas component against which the I/O was issued. For example, if the I/O is issued against Data Storage extent 1, the field contains DS1. If the I/O is issued against address converter extent 3, the field contains AC3. |
| IOFUNC | The type of I/O operation performed against an Adabas component. The values for this field are "READ" or "WRITE". |
| IOLIST | The hexadecimal I/O list for a command obtained from the Adabas command log record. Four bytes are allocated for each I/O list entry. |
| IOPHYS | A translation of the I/O list entry from
the Adabas command log record. The format for this field is COMP-X NNNNNN where
COMP is the Adabas component (ASSO, DATA, or WORK) X is the type of I/O, (R 'read' or W 'write') NNNNNN is the RABN (relative Adabas block number) |
| IORABN | The relative Adabas block number against which the I/O was performed. |
| IOTOCMD | The ratio of the total number of I/O operations performed to the total number of commands processed. |
| IOTYPE | Identifies the component against which the I/O operation was performed. Values for this field may be ASSO 'Associator', DATA 'Data Storage', or WORK 'Work dataset'. |
| IOVOLSER | Contains the volume serial number against which the I/O operation was performed. This field may be used to show Adabas I/O distribution. |
| TOTALIOS | Contains the total number of I/Os performed against all Adabas components for the Adabas session; the sum of ASSOREAD, ASSOWRIT, DATAREAD, DATAWRIT, WORKREAD, and WORKWRIT. |
| WORKREAD | Contains the total number of Work read I/O operations performed during the Adabas session. |
| WORKWRIT | The total number of Work write I/O operations performed during the Adabas session. |
