ClearPath OS 2200 Series Release 13.2 Software Planning and ...

5.9. COMUS
COMUS
COMUS is used to build products. Although COMUS installation functionality is still
supported in the current release, SOLAR has replaced COMUS as the installation tool for
all products.
General Considerations
• COMUS supports keyed product generation and keyed product installation.
• COMUS supports compressed and uncompressed 1/2-inch cartridge tapes. The
COMUS commands that accept and support 1/2-inch tape compression values are
INSTALL, REGISTER, and BUILD.
• Products installed with SOLAR do not update the COMUS database. Be sure to use
SOLAR reports to list the installed levels of these products, rather than the COMUS
system installation logs.
• Continue to use COMUS to build all symbolic products. Build information for
products installed with SOLAR is contained in an ASCII file for each product on the
package tape for that product.
• The LIBSAVE and LIBLOAD runstreams are no longer released with COMUS. The
runstreams are included with SOLAR, and will continue to be released in
SYS$*RUN$ on the Exec boot tape.
• The use of large program files (LPF) to build products is restricted.
• Do not specify the maintenance update levels of products in BUILD commands (for
example, use xR1 instead of xR1A).
• If you have any local or third-party products that are COMUS installable, consider the
following:
− COMUS does not support initiation of installation runstreams in demand mode
with the @ADD statement. You can either start the runstream during the install
session or enter the @START statement to initiate the runstreams.
− If there is a cycle limit on SYS$*DATA$, SYS$LIB$*RUN$, or
SYS$LIB$*PROC$, your installation might fail. COMUS and SOLAR create a +1
cycle of these files, which could cause a mass storage hold (M-hold) if the cycle
number tries to exceed the maximum. You are advised not to use cycle limits for
these files.
Refer to the COMUS End Use Reference Manual for detailed information regarding
product generation with COMUS.
ClearPath OS 2200 Release 12.0
COMUS Level 6R9
Compatibility
The following products either use the standard build routine (CB$STD$BUILD) provided
by COMUS and standard build skeletons (SKL-LDSVCTRL and SKL-LOADSAVE) or have
updated their product-specific build routines and skeletons in Release 12.0. These
products fully support the COMUS buffered-write and pool-id feature for the BUILD
command.
