System Management
A number of changes that affect system management have been introduced with RTR Version 3. The following sections describe these changes.
5.1 OpenVMS Quotas
RTR Version 2 used OpenVMS quota values specified on the RTR START command or calculated defaults. Because RTR Version 3 uses dynamic allocation (with the exception of the number of partitions that is statically defined), RTR does not calculate the required quotas, but depends on the system manager to configure quotas adequately. The value of maximum partitions is now set at 500. (See the RTR Release Notes for further information on partitions.)
For example, with RTR Version 2 you were required to explicitly specify the number of links or the number of facilities if defaults were too low. You no longer need to specify each RTR parameter value manually. Additionally, because RTR Version 3 uses mailboxes, you use the appropriate OpenVMS quotas to establish sufficient resources to support RTR Version 3 interprocess communication.
In RTR Version 3, all these parameters are governed by OpenVMS quotas. To establish these for RTR Version 3, DIGITAL recommends that you record the actual quotas used by RTR Version 2 on each node and add 50 percent to these values for RTR Version 3. See Table
5.2 Startup
There is a new RTR$STARTUP.COM file in SYS$STARTUP. It contains several changes including specifying RTR file locations, and choice of transport (protocol).
5.3 Creating Facilities
You create facilities the same way in RTR Version 3 as in RTR Version 2
5.3.1 Naming Nodes
With the addition of TCP/IP and
5.3.2 Modifying Facility Configurations
To modify facilities, you use the same procedures in RTR Version 3 as in RTR Version 2. One facility command has been changed:
SET FACILITY/BROADCAST=MINIMUM=n
has been changed to:
SET FACILITY/BROADCAST_MINIMUM_RATE=n
