AM-6060 Computer Owner's Manual, Rev. 00
If you decide to change the amount of memory allocated to a job, or the memory pool, you can modify
the system initialization file following the instructions below.
Be very careful when changing memory allocations. Most of the memory on an AM-6060 is
used for AlphaTCP processes and users connected via the network, and allocating memory
incorrectly could make it impossible for some or all network users to access the computer. Also,
changing the memory for AlphaTCP processes or available for network users may require
changes to one or more of the AlphaTCP configuration files, in addition to the initialization file.
Be sure to refer to your AlphaTCP Administrator’s Guide before changing any aspect of
AlphaTCP’s memory use.
Also, please refer to the System Operator’s Guide to the System Initialization Command File for
more information on SETJOB and SMEM.
1. Make a copy of the initialization file and edit it, as discussed previously.
2. To change the memory for a serial port or a background process, such as the AlphaTCP
TCPEMU server, scan through the file until you come to the SETJOB statement for that job. The
amount of memory for the job is immediately after the terminal name in the SETJOB statement.
You can increase or decrease this amount, as long as you keep in mind how much total memory
your computer has, and how much memory the other jobs, and the shared memory pool, need.
3. To change the amount of memory in the shared memory pool, find the SMEM statement; it
should be just after the last SYSTEM statement. Again, you can increase or decrease this
amount, but be sure to take all of your users’ memory needs into account.
Remember, the operator terminal—the one the computer boots on, connected to port #0—usually
gets all the memory not otherwise used. To increase the memory for this job, you need to
decrease memory use somewhere else; to decrease it, you can add memory to another job or the
memory pool.
In AM6060.INI, the operator terminal job is given 512KB of memory by a FORCE
command near the end of the initialization file. You can remove this command to give the
operator terminal all of the “left over” memory.
4. When you’ve made your changes, save the TEST.INI file and exit AlphaVUE. Then, perform a
test reboot by running MONTST as described earlier in this chapter. You can then use the STAT
or SYSTAT command to see how much memory is assigned to each job.
Multiple Initialization Files
The AM-6060’s CMOS menu feature lets you easily change the initialization file the computer boots
from. Because of this, we suggest you keep more than one initialization file ready for use. That way, if
you run into a problem with one file, you can change the CMOS setting and reboot using a different file
that you know is good. You can even have different files for different configurations: your usual file with
the network enabled and all ports defined, a simple single-user file, and possibly others.
