Page 6-7Setting up Your System
You may find you need more queue space if your computer makes heavy use of the file
locking system. The STAT program will show you the number of queue blocks
available—if this number often drops below 20, you may want to allocate more blocks.
The monitor initially contains 80 queue blocks; you may add more by using the QUEUE
command in the system initialization command file. Place the QUEUE command before
any SYSTEM commands. The QUEUE command allocates additional queue blocks.
For example, a QUEUE 20 line adds 20 blocks to the basic queue size of 80 to give a
total queue size of 100 blocks.
If you’re using a SCSI dispatcher, be sure to allocate a large number of queue blocks
(especially if write-caching is enabled). Start with an initial allocation of 2000 additional
blocks per hard drive, and adjust the allocation by observing the queue block usage
over an extended period of time.
The command line for adding 2000 queue blocks is:
QUEUE 2000

6.7SETTING UP INTER-TASK COMMUNICATION (MSGINI)
The MSGINI command creates a memory area for the use of the Inter-Task
Communication (ITC) system. This system makes it easier for devices and programs to
communicate, and is necessary for certain programs, such as the Task Manager and
the printer spooler. 16K is a recommended size. For example:
MSGINI 16K
6.8SETTING UP THE ERSATZ INITIALIZATION FILE
An ersatz name is a name that substitutes for a device/account specification. It serves
to make locations on your computer easier to enter and remember. For example, the
System Operator’s account, DSK0:[1,2], has the OPR: ersatz name. You can define
ersatz names for your own accounts by listing them in an ersatz INI file. Then you need
to add an ERSATZ command line in your system initialization command file to execute
your ersatz INI file at boot-up, so the computer knows what ersatz names have been
defined.
You can use the standard file name of ERSATZ.INI, or any unique name you choose.
You can also define multiple ersatz INIs in your initialization file. For example:
ERSATZ ERSATZ.INI
ERSATZ MYERZ.INI
