Explanation
One of the following occurred:
- The system determined that a shortage of processor storage would
occur if an address space is swapped in.
- The system could not swap in an address space because it was unable
to allocate enough central storage to contain the number of pages
in the swap-in working set.
In the message text:
- uuu
- The address space that owns the fixed pages.
- xxxxx
- The number of pages in the swap-in working set
- yyyyy
- The number of local system queue area (LSQA) and fixed pages that
the address space owns and that are on auxiliary storage and need
to be swapped in to central storage.
System action
The system leaves the address space swapped out
and checks periodically to see if it can be swapped in.
The
system considers the address space for swap in when either of the
following exist:
- The percentage of central storage that is fixed decreases enough
to swap in the address space without causing a shortage of pageable
central storage
- The number of available frames of central storage rises enough
to accommodate the address space's swap-in working set
If another attempt to swap in the address space is unsuccessful,
the system writes this message again. If the attempt is successful,
the system writes message IRA501I. If no action is taken, the system
continues to check periodically to determine if the address space
can be swapped in.
Operator response
If requested by the system programmer, quiesce
system activity and swap in the address space. Once swapped in, either
allow the address space to run to completion or cancel it.
System programmer response
Examine the validity of the address
space and determine whether it should continue. If the address space
should continue, request the operator to quiesce other system activity
and swap in the address space. If the address space should not continue,
request the operator to cancel the address space.
