USS Address Spaces attributes

The UNIX System Services Address Spaces attributes provide information about all z/OS address spaces (so-called dubbed address spaces) that have issued a call to the UNIX System Services application programming interface (API).

A/S Name The name of the address space. For a batch job, this is the jobname from the job statement. For a TSO address space, this is the userid of the logged-on user. IBM® Z OMEGAMON AI for z/OS may also generate address space names. An address space name consists of alphanumeric characters and follows the z/OS rules for address space names.

A/S Type Identifies the type of address space that is using UNIX System Services services. Valid values are JOB (batch job), STC (started task), or TSO (TSO user login).

ASID The numeric address space identifier. Its form is a positive integer in the range 0 through 65535. (This value is generally not useful when defining situations.)

Central Storage Frames Number of frames currently in use by this address space. Valid value is a 4-byte integer.

Client Time Service request block (SRB) time for this address space's preemptable SRBs and for the client; or related SRBs for which this address space is the client.

Client Time% Percentage of service request block (SRB) time for this address space's preemptable SRBs and for client-related SRBs for which this address space is the client. Valid value is a 4-byte integer.

Cold Frames Number of frames in UIC interval 4 as set by the System Resources Manager (SRM) via the RCEFRV# fields. Valid value is a 4-byte integer.

Cool Frames Number of frames in UIC interval 3 as set by the System Resources Manager (SRM) via the RCEFRV# fields. Valid value is a 4-byte integer.

CPU Time The total CPU time of the application using services provided by UNIX System Services. This is the sum of the TCB, SRB, and Client times.

CPU Time% Overall CPU percent (a value that represents TCB time + SRB time + Client time). Valid value is a 4-byte integer in the range 0-100.

Enclave Active Time The time the enclave has been active. Valid value is a 4-byte integer.

Enclave CPU Time CPU time used by the enclave.

Enclave CPU Service CPU service units received by the enclave. Valid value is a 4-byte integer.

Enclave TX Count Enclave transaction count. Valid value is a 4-byte integer.

Expanded Storage Frames Number of pages on expanded storage. Valid value is a 4-byte integer.

Home SRB Time CPU time for all types of preemptable SRBs (PSRB, CRSRB, ESRB) that are executing with this address space as their home address space.

Home SRB Time% Percentage of home CPU time for all types of preemptable SRBs (PSRB, CRSRB, ESRB). Valid value is a 4-byte integer in the range 0 - 100.

Hot Frames Number of frames in UIC interval 1 as set by SRM via the RCEFRV# fields. Valid value is a 4-byte integer.

ORIGINNODE The monitored z/OS operating system on which UNIX System Services is hosted. Valid value is a character string with a maximum length of 32 bytes.

Performance Group The performance group of the address space that is using services provided by z/OS UNIX System Services. A performance group is a class specified at installation that regulates the turnaround time of a user's jobs, jobsteps, and system interactions. This attribute is valid only when the system is in Workload Manager compatibility mode. Valid value is a positive integer in the range 0 through 65535.

Service Class The service class of the address space that is using services provided by z/OS UNIX System Services. This attribute is valid only when the system is in Workload Manager goal mode. Valid value is an 8-character alphanumeric name.

SRB Time Accumulated SRB time.

SRB Time% The percentage of CPU time used by the SRB. Valid value is a 4-byte integer in the range 0 - 100.

Step Name The name used on the execute statement for the program that is using z/OS UNIX System Services. For a batch job, for example, this is the name of a cataloged procedure specified by an EXEC statement. A stepname consists of alphanumeric characters and follows the z/OS rules for job name.

TCB Time Elapsed job step time.

TCB Time% Percentage of TCB CPU usage. Valid value is a 4-byte integer in the range 0 - 100.

Total Fixed Pages Total number of fixed pages in this address space. This value does not include shared pages. Valid value is a 4-byte integer.

Total Shared Pages Total number of shared page views in this address space. Valid value is a 4-byte integer.

UNIX System Time System CPU time for UNIX work.

UNIX System Time% Percentage of system CPU time for UNIX work. Valid value is a 4-byte integer in the range 0 - 100.

UNIX User Time User CPU time for UNIX work.

UNIX User Time% Percentage of user CPU time for UNIX work. Valid value is a 4-byte integer in the range 0 - 100.

Userid The user ID associated with the address space. For a batch job, the value is taken from the USER= specification on the job statement. Userid consists of alphanumeric characters and follows the z/OS rules for job name.

Warm Frames Number of frames in UIC interval 2 as set by SRM via the RCEFRV# fields. Valid value is a 4-byte integer.

Working Set Total of hot plus warm plus fixed pages. Valid value is a 4-byte integer.
