The "Midnight" Job
A reminder: did you check the Change
Log for the
install.pl wizard? It tracks changes and bug
fixes to that script, as well as listing the known problems.
The AIPS "Midnight" (MNJ) job allows you to keep up with
the latest development, bug fixes, and changes in AIPS. Originally
designed for use within NRAO among the different sites, it has been
extended to many outside institutions in both the US and elsewhere in
the world. You may run the MNJ automatically if you set up cron to do
so, but you may also run the MNJ by hand only when the mood strikes
If you wish to run the MNJ, you must first install AIPS.
Instructions for that are found in 31DEC15
release and 31DEC14 release. The
former will be updated every day until the end of 2015, so a MNJ run
at any time in 2014-2015 should work. The latter will be updated
daily through December 2014 and may be updated on occasion (for
patches) thereafter. Thus a MNJ on 31DEC14 will work through 2014 and
may work without error messages (and do useful stuff) in 2015. Note
that a MNJ will update documentation and source models at any time
since they are not treated as version-dependent files. MNJs on older
versions may also run and, rarely, do useful things like fetch
documentation files. Of course, some of them will apply only to
current versions, not the one for which the MNJ was run.
install.pl script invokes the
MAKE.MNJ shell script; this now takes care of all the
setup for the midnight job. All you have to provide is a start date
(use the day before you fetched the
31DEC15x.tar.gz file which is the default in
install.pl script can now do a
binary installation for Solaris Ultra, MacIntosh OS/X (PPC and Intel
cpus), and Linux (32- and 64-bit) computers in the 31DEC09 and later
versions. The binary installation uses
rsync to copy the
text and binaries from Socorro. Having done a binary installation,
the MNJ will use cvs to update text files and rsync to update binary
areas. You do not need to copy the tar.gz file for a binary
installation; it takes care of all that for you.
There are certain minimal requirements for running the midnight
- A computer on which AIPS already runs (!) and which is connected to
the internet (need not be full time);
- A version of perl (included with
most Linux distributions);
- A working version of the
maintenance system. The secure shell is no longer required.
If cvs is not in your $PATH, MAKE.MNJ will ask you where it is
to be found. Be sure that you can answer that before running
the MAKE.MNJ portion of install.pl.
rsync must also be available and enabled for binary
Below are some tips that may make it easier to install/update:
- type, e.g.
perl ./install.pl (or
./install.pl -n if binary)
- When done, make sure to get the new definitions:
|For bash, ksh, zsh||For tcsh, csh|
- You may make a cron entry for the
MAKE.MNJ creates for you.
Alternatively, you may run it by hand at any time you wish.
- It almost certainly has to run from the account that installed
- You must run from an account that is able to send mail. Please
make sure that the
specifies mail account(s) that are read regularly. Some sites
start their cron job and fail to notice that it fails on a daily
basis and fail to read the e-mails we attempt to send them
asking for things to be corrected. It helps if you notify us to
give us a person to contact regarding your MNJ. Or better yet,
subscribe yourself with the list
That's it. Given halfway reasonable network connectivity, you should be
able to let it run unattended if you have cron run the MNJ.
The MNJ goes on working on an AIPS version even though that version
is no longer the development vesrion at NRAO. When the version is
fully frozen, then you need only run one more MNJ to bring your
version up to do with that final version. Further executions of the
MNJ will produce error messages most of the time because files showing
the date no longer advance. The "frozen" version may be updated with
patches once in a while during the year following its freezing, so the
MNJ may run without complaint once in a while. Subscribe
to bananas if you wish to be informed of those times. Subscribe
to mnj if you wish to be informed of those times or any other mnj
