At
the time of a critical pageable storage shortage, the system identifies
20 address spaces with the largest fixed frame allocation in the system.
 These address spaces get displayed and the operator is able to cancel
one of these address spaces using the outstanding WTOR message IRA421D.
In
the message text: return-code
The return-code indicates the type of the detected
shortage. The order in the list below indicates how severe the shortage
is. The most severe type is at the top of the list. The possible values
for return-code are as follows: 3
Pageable frames below 16 megabytes shortage
4
Pageable frames between 16 megabytes and 2 gigabytes shortage
2
Pageable frames in real storage shortage
1
Pageable to auxilary (PTA) frames in processor storage shortage
because of too many DREF and fixed frames.

ii
Number of the line for the cancel
uuuuuuu
Non-swappable address space name of the space with the high fixed
frame increase.
aaaa
Address space ID of the user.
N
A non-cancelable address space.
S
A system address space.
xxxxxxxx
Number of frames the user owns.
zzzzzzzz
Number of frames in the shortage area the user owns.

System action
The system display shows a list of address spaces,
with the highest fixed frame allocation in the shortage area.  With
a reply ‘1’ to ‘5’ at WTOR IRA421D the operator
can cancel one of these address spaces.

Operator response
If requested by the system programmer, reply
the WTOR IRA421D with ‘1’ to ‘5’ to cancel
one of the five address spaces.  Or reply with ‘M’ to
display the next five address spaces, which you then can cancel.

System programmer response
Examine the validity of the address
spaces and determine whether it should continue.  If one of the address
space should not continue, request the operator to reply with ‘1’
to ‘5’; otherwise, request to reply with ‘M’
to display the next five address spaces.
