Limiting Use of Timer
Commands
Unlimited use of timer commands, such as EVERY, can inadvertently flood a system
and consume its resources. Use the SYSPARMS command’s EVCMDMIN operand to
regulate the minimum repeat frequency permissible for an EVERY command. For
example, to specify a minimum repeat frequency of 15 seconds, issue the following
command:
SYSPARMS EVCMDMIN=15
Specify EVCMDMIN in seconds, as an integer from 0 through 300. A value of 0 means
that the EVERY command is to be executed immediately. The default value is 10
seconds.
Setting Message Queue
Limits
OCS windows store messages that they receive but cannot immediately display. Users
can change the size of the message queues by issuing the PROFILE command. You
can set the maximum size of the queue for roll-delete and non-roll-delete messages.
Setting Roll-Delete Message Queue Size
Use the HELDMSG operand of the SYSPARMS command to specify the maximum size
of the roll-delete message queue associated with an OCS window and the maximum
value a user can specify with the PROFILE HOLD command. Specify the values as
two integers offset by a comma and surrounded by parentheses. The integer in the
first position specifies the number of messages queued for display on an OCS window
when the window is in the HOLDING or AUTOHOLD state. Specify the value as an
integer from 0 through 300.
The second integer specifies the maximum queue size that a user can set by issuing the
PROFILE HOLD command. Specify the maximum queue size as an integer from 10
through 999. The value of the first integer cannot exceed that of the second.
For example, to specify a maximum roll-delete message queue size of 100 (and prevent
the user from trying to exceed the limit with the PROFILE HOLD command), issue the
following command:
SYSPARMS HELDMSG=(100,100)
The default roll delete message queue size is 200 messages.
Setting Non-Roll-Delete Message Queue Size
Use the NRDLIM operand of the SYSPARMS command to specify the maximum
number of messages retained by the central non-roll-delete (NRD) message queue.
Specify NRDLIM as an integer from 10 through 10000. For example, to specify a
maximum NRD message queue size of 500 messages, issue the following command:
SYSPARMS NRDLIM=500
The default NRD message queue size is 200 messages.
