details commands and procedures in MPE that can improve your
productivity with HP 3000 systems.
How do we
find out how much memory is installed on a machine?
Heres a simple way, though it requires you to be logged
on somewhere with PM capability:
Main memory = , [$c0000ca8] / #512 : #,
memory = #320 MBs
are several free ways; one is by running CSTM (SYSDIAG on pre-6.5
systems), and another is by running sysinfo. If you own Glance/iX or
Lunds SOS, these tools will also tell you how much memory is
installed (and a lot more).
external modem port (just below the internal modem port on the IO
card) accessible on the HP 3000?
between internal and external modem port with the CA command
(configure access port) at the Ctrl-B prompt. Use CO to get back to
regular console mode (leave Ctrl-B prompt). Some more Ctrl-B prompt
info can be found at docs.hp.com/cgi-bin/doc3k/B3265090496.13461/94
I have a
patch for FTP (FTPHD68A) that I want to install. Theres no
indication as to whether it requires a reboot or not. Do all HP 3000
patches require reboots, or just some?
patches do not require a reboot.
trying to set up a test box. When I boot the system up it only goes
to INIT C200. I look at the back of the system and I see the XCVR/NET
FAIL light flashing. How can I fix the problem?
could be youre not waiting long enough. 9x7 boxes with a lot of
memory can take 10 minutes or more to do a memory check.
We have a
program that is locking a dataset and never unlocks it. Is there a
simpler way to force a dataset to unlock than to to reboot the
Usually the first thing to try is :ABORTing the program. When
the database is closed, it implicitly unlocks the datasets. If it is
in a state where you cannot abort it, such as trying to obtain a
second [unconditional] lock, then you are getting into a deadly
embrace situation. This is where UNDEDLOCK that others have
mentioned will help. If you can re-write your program, then you need
to investigate what it is trying to lock, whether or not
it is getting into a deadly embrace, and/or if some
programmer simply forgot to code a call to DBUNLOCK.
Likewise, other programs should be abortable
[press <break>, then type ABORT at the prompt]. If they cannot,
then perhaps they are the co-conspirator in the deadlock situation.
Again, if you have access to the source, it is time to look into
these to determine why locks are being held for so long.
I have a F/W
card connected to a HASS unit. What is the SCSI access priority?
Guy Paul replies:
SCSI priority is in this order: 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13,
12, 11, 10, 9, 8, and 7 is usually set for the adapter card.
What does the
R stand for in the JIN column below?
IPRI JIN JLIST INTRODUCED JOB NAME
EXEC 10 R LP FRI 10:16A BACKG,MGER.VESOFT
Its there because the job has the RESTART option on the
job card. Most jobs dont use it unless you want the job to
restart completely after a START RECOVERY reboot.
