TRYING TO CLEAN UP SYSTEM FOR A RUNTIME
ITEM: RTA000028785
I would like to know what /usr/lpp/bos/inst_root is used for
once all packages are installed and committed on a system. Can they
be removed off the system or what. I also see things like
inst_U*, can those go away?
On the systems we are trying to make only runtime we are trying
to clean up some things. In /usr/lpp/X11/lib there are some big
library files, can these go. The only access as far as X-Windows
will be from TCP/IP using PMX under OS/2 on PS2's. They will only
be using different size aixterm fonts with no programming on those
boxes. We have some main 6000's in house for X programming.
There is the following directories under /usr/lpp that relate to
X - X11, X11fnt, X11rte. I don't want to wipe out anything that
can cause problems, but it would seem like to just have runtime
I would delete /usr/lpp/X11? I have already deleted the Xamples.
In Cobol, there is /usr/lpp/COBOL, cobolcmp, cobolrte,
cobolrtemEn_US, do we get rid of cobolcmp and COBOL to have a just
cobol runtime also?
I have looked in the Risc/6000 System overview book and all it
says it what the sizes are for each piece. What I can't find any-
where is what directories must stay for runtime and what must
stay for development.
---------- ---------- ---------- --------- ---------- ----------
A: I will address your questions in order:
1) Can I remove /usr/lpp/bos/inst_root or the inst_U* files?
You should NOT delete the files in the /usr/lpp/bos/inst_root
directory because it will cause lppchck error as well as others.
The inst_root directory also contains several symbolic links which
make it appear larger than the one Megabyte it really contains.
All the files and subdirectories in the following directories may
be removed for those PTFs and LPPs that are in the COMMITted
state.
/usr/lpp//inst_U*
/usr/lpp//deinstl
where "" is the name of an LPP or PTF.
2) Can I delete the libraries in /usr/lpp/X11/lib?
Some of these libraries are Run Time Libraries, and others are
for development. I will list them below for your convenience.
This information for each library can be found in InfoExplorer.
libMrm.a Development Environment
libUil.a Development Environment
libX11.a Run Time Environment
libXdmcp.a Development Environment
libXext.a Run Time Environment
libXfx.a Run Time Environment
libXm.a Development Environment
libXmu.a Created when the Xamples are made
libXt.a Run Time Environment
liboldX.a Run Time Environment
3) Can I delete /usr/lpp/X11 and retain the X11 Run Time Environment?
Plus how can I only have the COBOL RTE on my system?
Both of these questions have the same answer. Have your SE
receive a utility off the TOOLS disk called "rmlpp". This
is used to remove an LPP. Using this tool, remove X11 and COBOL,
then install just the X11 RTE and COBOL RTE. With COBOL, you
can install the Compiler, which includes both the compiler and
the RTE, or just the RTE. It looks like you have installed the
compiler because both are on your system.
The reason for this suggestion is that there is more involved in
removing an lpp than just deleting it. The ODM on AIX keeps track
of what is installed on each system for licensing and updating
procedures. Deleting files from an lpp does not update the ODM,
which means the ODM still believes something is still installed
when in fact it isn't. This could cause some messy problems on
the system.
This is the simplest and safest way to do what you would like to
do.
