Address space SRM activity
- JPCI
- Displays address space common area page-ins.
- Type:
- Minor of address space majors
To display this value as a rate, use an argument of .R.
- JPGS
- Displays pages stolen from address space.
- Type:
- Minor of address space majors
To display this value as a rate, use an argument of .R.
- JPUI
- Displays address space page-ins.
- Type:
- Minor of address space majors
To display this value as a rate, use an argument of .R.
- JPUO
- Displays address space page-outs.
- Type:
- Minor of address space majors
To display this value as a rate, use an argument of .R.
- JRCM
- Displays composite job recommendation value.
- Type:
- Minor of address space majors
This value is calculated as:
JRCM = JRCP + JRIO + JRWL + JRSTAt certain times, the numbers may not add up to JRCM due to SRM algorithm adjustments.
- SUAL
- Displays total service units since the last swap-in.
- Type:
- Minor of address space majors
This value is calculated as:
SUCP + SUIO + SUMS (All service units)The service units for nonswappable address spaces are calculated about every 20 seconds. Keep this in mind especially when you use the .R rate argument.
- SUCP
- Displays CPU service units since the last swap-in.
- Type:
- Minor of address space majors
The service units for non-swappable address spaces are calculated about every 20 seconds. Keep this in mind especially when you use the .R rate argument.
- SUIO
- Displays I/O service units since the last swap-in.
- Type:
- Minor of address space majors
The service units for non-swappable address spaces are calculated about every 20 seconds. Keep this in mind especially when you use the .R rate argument.
- SUMS
- Displays Main Storage Occupancy (MSO) service units since the
last swap-in.
- Type:
- Minor of address space majors
The service units for non-swappable address spaces are calculated about every 20 seconds. Keep this in mind especially when you use the .R rate argument.
- SUPR
- Displays service units at beginning of period.
- Type:
- Minor of address space majors
The service units for non-swappable address spaces are calculated about every 20 seconds. Keep this in mind especially when you use the .R rate argument.
- SWPR
- Displays swap reason.
- Type:
- Minor of address space majors
Swap reasons can be any of the following:
- Exchange
- Exchange swaps (control domain MPL)
- Unilatrl
- Unilateral swaps (control system MPL)
- Long-Wat
- Long wait (address space asked to wait more than 0.5 second)
- Det-Wait
- Detected wait (address space was found waiting)
- Term-In
- Terminal input wait (TSO waiting on user input)
- Term-Out
- Terminal output wait (TSO waiting for TCAM/VTAM output buffers)
- Aux-Strg
- Swapped to correct a shortage of auxiliary storage
- Real-Str
- Swapped to correct a shortage of real storage
- Request
- Swapped by SRM for system activity (e.g., reconfigure storage to accommodate real storage address spaces)
- Enq-Xchg
- Swapped to expedite the processing of an enqueue by its owner
- Transwap
- Swapped while in transition from swappable to nonswappable status
- Cent-Str
- Swapped out to improve central storage availability
- Sys-Page
- Swapped out to reduce the system page fault rate
- Too-Long
- Swapped out to enable the swap-in of an address space that had been swapped out too long
- APPC Wt
- Voluntary swap-out of an idle APPC address space
If the last letter of the wait reason is an asterisk (*), the address space is ready to do work, but the SRM did not yet swap it back in. For example, if the system is busy and users press Enter, they are ready to do work. But since the system is so busy, the SRM did not have time to swap them back in. Their swap reason code is Term-In*.
