On
OpenVMS nodes, another component of the LAT software, the LAT Ancillary
Control Process (LATACP), maintains the database of available nodes
and services. The nodes and services can be those that are multicast
from remote LAT nodes, or they can consist of the local node and
one or more local services that you create on your own system. The
maximum size of this database is dependent on the value of the system parameter
CTLPAGES.
After you enter a LATCP command, you might get the following
response:
%LAT-W-CMDERROR, error reported by command executor
-LAT-F-ACPNOCTL, insufficient resources - ACP CTL/P1 space limit reached
If so, this signifies that the database size has reached the
CTLPAGES limit. You can correct the situation in one of three ways:
Reduce the size of the database by
reducing the node limit. Use the LATCP command SHOW NODE to display
the node limit; use the command SET NODE/NODE_LIMIT to change it.
For more information, refer to the HP OpenVMS System Management Utilities Reference Manual: A--L.
Reduce the size of the database by reducing the
user group codes that are enabled on the node. Use the LATCP command
SHOW NODE to display the enabled user group codes; use the command
SET NODE/USER_GROUPS=DISABLE to disable some of them. For more information,
refer to the HP OpenVMS System Management Utilities Reference Manual: A--L
. If you choose this step, you must also edit your startup procedures
to change the user groups that are enabled each time the system
reboots. For more information, see
Customizing LAT Characteristics.
Extend the size of the database by increasing the
value of the system parameter CTLPAGES. As a general rule, note
that every unit of CTLPAGES that you increase is roughly equivalent
to six additional nodes or services that will be stored in the database. After you change CTLPAGES, you must reboot the system for
the changed value to take effect. Make sure you add the increased
value of CTLPAGES to the AUTOGEN parameter file MODPARAMS.DAT. For more
information about changing values of system parameters, see
Recommended Method for Changing Parameter Values.
