Performance analysis and tuning tool

SarCheck is an inexpensive tool developed to help system administrators with UNIX performance tuning. It does this by monitoring system utilization, identifying problem areas, and recommending changes to the system's tunable parameters. SarCheck translates your system's sar reports into a Plain English report. SarCheck can detect CPU Bottlenecks and runaway processes, I/O bottlenecks, improper I/O load balancing, slow disk devices, memory bottlenecks and leaks, inefficient system buffer cache sizing, improper system table sizes, and inefficient PATH variables. The resource analysis and recommendations sections of SarCheck will analyze the data and make recommendations for gradual changes to your system. The capacity planning component of SarCheck will approximate the amount of capacity left on your system and determine which resource is likely to become exhausted first.

The Skunkware release of SarCheck is the freely contributed UltraLite release.

afio - manipulate archives and files

Afio makes cpio-format archives. It deals somewhat gracefully with input data corruption, supports multi-volume archives during interactive operation, and can make compressed archives that are much safer than compressed tar or cpio archives. Afio is best used as an `archive engine' in a backup script.

Hog - memory, cpu and i/o hog analyser

The hog commands analyse resource use by processes. The hog commands all work in the same basic way, but observe the consumption of different resources. memhog examines memory use, cpuhog examines processor use, and iohog examines I/O use. In the following discussion, hog means one of the possible invocations (e.g., memhog), and resource refers to the resource in which that hog is interested.

hog runs in a loop. Each time it loops, the resource consumption for each process is obtained from the kernel, and a ``hog'' value computed, based on a resource-specific algorithm. The algorithm is intended to measure the overall impact of a process on the resource. After the ``hog'' values are computed, the processes are displayed in descending ``hog'' order. Thus, the process at the top if of the display is using the most resource. Note that a process with a ``hog'' value of zero will not be displayed. hog is terminated by sending it SIGINT.

Each process is represented in the display by a single line, with the pid and uid associated with the process on the left, and the command being executed on the right. In the middle are resource-specific numbers. The top line of the display contains a legend, and possibly some overall system statistics relating to resource.

SCO UnixWare 7 Help API

The UW7 Skunkware team is very proud to be able to bring to you the public release of the SCO UnixWare 7 Help API.

The SCO UW7 Help API provides a low-level context-sensitive help api for use with the SCO UW7 ScoHelp system. X11 graphical clients wishing to provide context-sensitive help via the ScoHelp facility can utilize the SCO Help API contained herein.

The callable low-level scohelp api enables other Motif applications to act as scohelp "clients", thus allowing requests to be made of scohelp to display specific topics. Topics can be either "hard coded" using the actual topic name, or can be a "widget tree" name. "Widget tree" names are intended to be used by a higher level api; the direct user of the low-level api will use only "hard coded" topic names.

SCO UW7 Skunkware Help Api (helpapi package) contains the following files:

/usr/X11R6.1/include/X11/scohelp/api.h
    (Help Api header file)
/usr/X11R6.1/lib/libhelp.so
    (link to libhelp.so.1.0)
/usr/lib/scohelp/en_US.ISO8859-1/SDK_helpapi/
    (Help Api Documentation)
/usr/lib/helpapi_example/api_test.c
    (example C file)
/usr/lib/helpapi_example/api_test.mk
    (example MAKE file)
/usr/lib/scohelp/hooks/api_book.hk
    (example hook file)
/usr/lib/scohelp/en_US.ISO8859-1/api_book/
    (example help documents)

Please use pkgadd to install helpapi.pkg

To build the example program (make sure the udk package has been installed):

mkdir $HOME/api_test
cd $HOME/api_test
cp /usr/lib/helpapi_example/ .
make -f api_test.mk

You can then run the example program api_test. From the api_test window, pressing F1 key or clicking on any item on the Help menu will open a netscape window which displays the corresponding example help document. Note that if your system is using a Documentation Server other than localhost, you will need to install the example documentation on the Documentation Server.

Please view the SCO UW7 Help Api Documentation from scohelp for additional details after you install the Help Api on your system. You may want to run /usr/man/bin/config_search -f to help you with finding the Help Api pages by scohelp searching.

IP Address Alias Manager

The "IP Address Alias Manager" administers network addresses for configured IP interfaces - enabling the virtual domains services in both FTP server and mail delivery.

Currently UnixWare 7 does not have a manager to do this and the administrator has to set up the aliases by hand.

Included in the image is a set of HTML pages that are added to SCOhelp at install time. The doc is under Networking -> Administering TCP/IP and Internet services -> Configuring IP Address Aliases.

The package is fully removable and can be installed with the command:

    # pkgadd -d <mount-point> ipalias

KBackup - a user friendly yet powerful backup program

KBACKUP is intended for handling of backups no matter whether they reside on disk or tape or even in files. As most other backup programs available today are either confusing the user with lots of long command line options or user friendly but not powerful at all, the aim behind writing KBACKUP was to provide a user friendly yet powerful backup program. It is compatible with existing and well proven archive formats so you can restore your archives even if you should not have KBACKUP around anymore.

To achieve this goal, KBACKUP uses established and well proven archive tools like tar(1) or afio(1) to do the archive handling and improves their functionality by adding quite a lot of additional features. By using the dialog(1) program archive handling is as easy and user friendly as possible. This means that you will get the power and reliability of the best archive handlers combined with a customisable and easy to use interface.

Pkgadd/pkgmk and family

The OpenServer release of the standard UnixWare packaging tools. Useful in preparing distributions built with the UDK for subsequent installation on either OpenServer or UnixWare.

Process and core information

proc is a tool for displaying information from a running process or core image. It accepts either the name of a core file, a process id or a pathname in the /proc directory. By default, it produces a summary listing of process level information, similar to that provided by the ps command. You can ask for a fuller listing and for detailed reports about each LWP in the process, including the contents of the registers. You can also get a memory map of the process. For full details see the manual page, proc.1.

The current source will build under UnixWare 2.1.x or UnixWare 7. The distribution was built using UnixWare 7, bl15.2v1e. To build, simply invoke: make -f proc.mk

proc is a dynamically-linked ELF binary that will run on UnixWare 2.1.x or UnixWare 7 (gemini). It may be installed anywhere that is visible from your PATH.

proc does not run under OpenServer, since it requires the facilities provided by the /proc filesystem.

msize is a simple shell script that uses proc -m to print out the memory size of a running process. usage is: msize process_id.

proc was written by Joel Silverstein, jds@sco.com. The source is owned by SCO and will probably be part of a future SCO product. msize was written by David Prosser, dfp@sco.com.

Red Hat Package Manager

The Red Hat Package Manager (rpm) can be used to create RPM format packages and, more appropriately on SCO platforms, to install RPM format packages for use in conjunction with the Linux Emulation System (lxrun).

Top - display top cpu processes

Top displays the top 15 processes on the system and periodically updates this information. Raw cpu percentage is used to rank the processes. If number is given, then the top number processes will be displayed instead of the default.

Top makes a distinction between terminals that support advanced capabilities and those that do not. This distinction affects the choice of defaults for certain options. In the remainder of this document, an "intelligent" terminal is one that supports cursor addressing, clear screen, and clear to end of line. Conversely, a "dumb" terminal is one that does not support such features. If the output of top is redirected to a file, it acts as if it were being run on a dumb terminal.
