3.1 Resource requirements
The files supplied with the technical delivery unit CRTE-BAS oc-
cupy
*4 approx. 9,300 PAM pages.
An additional
*4 approx. 11,500 PAM pages
are required for SX servers
Installation of POSIX-HEADER V1.5A and CRTE V2.5A in POSIX takes
up around 4.7 MB in the root file system.
The following space is required in class 4 memory for loading the
subsystems:
CRTEBASP 4340 KB (only for RISC-SPARC systems)
CRTEBASY 2570 KB
CRTEPTH 2610 KB
CRTEPTP 4400 KB (only for RISC-SPARC systems)
*4 All subsystems are loaded by default into the class 4 memory
*4 above 16 MB.
3.2 Software configuration
CRTE-BAS V1.5A is included in BS2000/OSD-BC as of V5.0 and in
OSD/XC as of V1.0.
3.3 Product installation
Installation of the technical delivery unit CRTE-BAS with the in-
stallation monitor IMON is mandatory. The information concerning
installation in the delivery cover letter and in the product
documentation must be followed as well as the information in this
Release Notice.
The necessary inputs and the sequence of the installation are de-
scribed in the IMON documentation.
The standard installation of POSIX-HEADER in the POSIX file sys-
tem is made either directly with IMON or with the POSIX installa-
tion tool after installation with IMON.
The following additional installation forms are also described in
the CRTE V2.5A manual:
• Installation to a non-standard ID
• Private installation
• Installing the header files and link switches in any desired
POSIX directory
The CRTEBASY subsystem and possibly CRTEBASP as well as CRTEPTH
and possibly CRTEPTP from the CRTE-BASYS V1.5A delivery unit, are
provided as the runtime environment for BS2000 internal programs.
The subsystems should only be preloaded if this is recommended in
the Release Notice of another installed product.
The subsystems are loaded into upper class 4 memory by default.
As an alternative, the subsystems can also be loaded into class 4
memory below 16 MB using the supplied subsystem declaration files
(with the extension LOW), if enough space is available there.
