Table 7–9 Descriptions of SYSTEM and DEFAULT Accounts
Account Description
AST Queue Limit
(ASTlm)
Limits the sum of the following amounts:
• The number of asynchronous system trap (AST) requests that a user’s process
can have outstanding at one time
• The number of scheduled wakeup requests that a user’s process can have
outstanding at one time
This limit affects all system services that accept an AST address as an argument,
and the Schedule Wakeup ($SCHDWK) system service.
If the deferred write option (DFW) is enabled, the number of ASTs used per file
is equal to 1, plus the number of record streams, plus the multibuffer count.
Otherwise, the number is 1 plus the number of record streams.
