Reason:

This message appears when you request control file statistics with the DISPLAY IO command, and displays information about I/O activity for CA MIM control files. The above display is issued for a virtual control file. If this were a display of a DASD control file, the third line of the display would show the FILE number, data set NAME, and UNIT address.

The non-indented lines display global statistics that have been accumulated since the last time you formatted this control file. The indented lines display local statistics that have been accumulated since the last time you started CA MIM.

Additional text appears if you have issued a DISPLAY IO=RESET command since the last time you started CA MIM. These additional lines display statistics that have been accumulated since the last time you reset this display.

Note: If M appears after a statistic, then that number is measured in millions.

The following information is shown for each control file:

COMMUNICATION

Displays the CA MIM communication method selected.

CURRENT

Displays the current control file communication method in use, if COMMUNICATION=CTCDASD.

INITIAL

This field is displayed only when the CTCDASD communication method was selected, and indicates the initial control file method chosen, CTC or DASD.

MODE

Displays the control file processing mode as set by the SETOPTION MODE command.

CYCLES

Displays the control file service cycle value as set by the SETOPTION CYCLES command.

INTERVAL

Displays the control file service interval value as set by the SETOPTION INTERVAL command.

MASTER SYSTEM

Displays the master system for the virtual control file.

CURRENT PATH

Shows the current CTC path address. This field is not applicable for non-CTC communication methods.

DSPNAME

If the virtual control file is active, then the DISPLAY IO command response message will display the VCF data space name. This information will only be present on a CA MIM system.

TOTAL BLOCKS

Indicates how many blocks have been allocated for this control file.

MAX USED

Displays the maximum number of blocks this control file has used since the last time this control file was formatted.

FREE

Displays the current number of available blocks on the control file.

BLKSIZE

Displays the size of each block on the control file. If the current file is a list structure, this field will be a multiple of 4096, rather than the value coded on the MIMINIT BLKSIZE statement.

LAST FORMAT

Displays the date the primary control file was formatted last.

TOTAL READS

Indicates how many data blocks CA MIM has read since the last time this control file was formatted.

WRITES

Indicates how many data blocks CA MIM wrote since the last time the control file was formatted.

LAST RESTART

Displays the time and date you started CA MIM on this system.

COUNT

Displays raw totals for the local system. The following information appears:

CYC

Indicates the number of times the local system has accessed this control file.

BLOCKS READ

Indicates the number of blocks this system has read.

WRITTEN

Indicates the number of blocks this system has written.

XACT READ

Indicates the number of transactions this system has read.

XACT PROCESSED

Indicates the number of transactions this system has acted on.

XACT WRITTEN

Indicates the number of transactions this system has written.

AVG

Displays averages per control file cycle for the local system. The following information appears:

CYC

Indicates the average duration, in seconds, of a control file cycle for this system.

BLOCKS READ

Indicates the average number of blocks this system has read per cycle.

WRITTEN

Indicates the average number of blocks this system has written per cycle.

XACT READ

Indicates the average number of transactions this system has read per cycle.

XACT PROCESSED

Indicates the average number of transactions this system has acted upon per cycle.

XACT WRITTEN

Indicates the average number of transactions this system has written per cycle.

RATE

Displays averages per second for the local system. The following information appears:

CYC

Indicates the average number of control file cycles per second.

BLOCKS READ

Indicates the average number of blocks this system has read per second.

WRITTEN

Indicates the average number of blocks this system has written per second.

XACT READ

Indicates the average number of transactions this system has read per second.

XACT PROCESSED

Indicates the average number of transactions this system has acted on per second.

XACT WRITTEN

Indicates the average number of transactions this system has written per second.
