Record type 90 (X'5A') — System status

Record type 90 is written during initialization processing and whenever certain operator commands are issued. This variable length record is created for operator tracking and reporting of reliability data. It allows the installation to establish availability statistics.

Note:

The type 90 record does not contain a standard SMF record header with subtypes. The subtype value for the type 90 record resides in the SMF90TID field of the product section. The SMF dump utilities, IFASMFDL and IFASMFDP, do not support subtype selection via the TYPE option of the OUTDD parameter for type 90 records. End of change

The following events cause the recording of this record during IPL. (See the Product Section for the individual subtype indicator.)

HALT EOD command
IPL
RESET command
SET DAE command
SET DATE command
SET IEFOPZ command
SET MPF command
SET OPT command
SET PFK command
SET PROG command
SETSMF command
SET SMF command
SET SMFLIM command
SET TIME command
SWITCH SMF command
VARY WLM command

Subtype 2 is written only if the CLOCK parameter is not specified on the SET DATE command. Any SET DATE command that uses the CLOCK parameter produces a subtype 1 record.

Subtype 8 is written only when the operator responds to message IEE956A, the system prompt for information about the IPL.

Subtype 23 is written each time the workload management service definition is installed on the WLM couple data set. A service definition is installed on the WLM couple data set by a function in the WLM ISPF application.

Subtype 24 is written each time a workload management service policy is activated. A service policy can be activated either by the VARY WLM command, or by a function in the WLM ISPF application.

Subtype 29 is written each time a LNKLST set is activated for the LNKLST concatenation, except during LNKLST set activation at IPL through the ACTIVATE statement in PROGxx - SMF is not active this early in IPL. Subtype 29 is written when the SET PROG and SETPROG LNKLST commands are issued after IPL to activate a new LNKLST set.

Subtype 30 is written each time a RESET operator command completes successfully. The record identifies the job that was reset, the operator who initiated the command, and the change that was requested.For an enclave, the record identifies the name of the owner address space, the user and application that initiated the request, and the change that was requested.

Subtype 31 is written each time that a module has been added to or deleted from LPA after IPL through the SETPROG LPA command, the LPA statement of the PROGxx parmlib member through the SET PROG=xx command, or the CSVDYLPA macro.

Subtype 32 is written each time there is a successful policy change.
