Honza’s perspective

Another post, where the main audience is me :)

Installation

To install IBM Rational Requirements Composer 2.0.0.1 on 64bit Linux, you need 32bit libraries installed. Strange error message is displayed otherwise when trying to run the installer:

root@rtc:/opt/rrc-install/RRCS_SETUP/InstallerImage_linux# ./install
bash: ./install: No such file or directory

To install the needed libraries run:

apt-get install ia32-libs

The installation should run successfully after this.

Startup

RRC needs swt-gtk to run. Install it by:

apt-get install libswt-gtk-3.4-jni

In addition, RRC needs a X screen to start. There is an IBM Technote with solution for RHEL and Suse. To install Xvfb on Ubuntu do:

apt-get install xvfb

The rest of the procedure (starting the server) is the same as on RHEL or SLES (see the technote).

The server is started by server.startup. This script has to be called from its directory – you need to cd first. The init script can look for example like this:

#!/bin/bash
#
# rrc        Startup script for the RRC
#
# chkconfig: - 90 16

start() {
        echo -n $"Starting $prog: "
        # export GTK_PATH=/usr/lib32/gtk-2.0
        Xvfb :1 -screen 0 800x600x24&
        cd ${rrchome}
        DISPLAY=localhost:1.0 ./server.startup
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && touch ${lockfile}
        return $RETVAL
}

stop() {
        echo -n $"Stopping $prog: "
        ${rrchome}/server.shutdown
        RETVAL=$?
        killall Xvfb
        echo
        [ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}
}

  start)
        start
        ;;
  stop)
        stop
        ;;
  status)
        status $prog
        RETVAL=$?
        ;;
  restart)
        stop
        start
        ;;
  *)
        echo $"Usage: $prog {start|stop|restart}"
        RETVAL=3
esac

exit $RETVAL
