Tungsten Clustering™ has a wide range of tools and functionality available
for checking and managing the status of a dataservice. The majority of the
management and information structure is based around a small number of
command-line utilities that provide a complete range of tools and
information, either through a direct command-line, or secondary shell like
When installing the dataservice using tpm , if requested,
the login script for the staging user (for example
.bashrc ) will have been updated to
execute a script within the installation directory called
env.sh . This configures the location of the
installation, configuration, and adds the script and binary directories to
PATH so that the commands can be executed without having
to use the full path to the tools.
If the script was not added to the login script automatically, or needs to
be added to the current session, the script is located within the
share directory of the installation directory. For
/opt/continuent/share/env.sh. To load into the
current session use source. See
Section 5.2, “Establishing the Shell Environment” for more information.
The main tool for controlling dataservices is cctrl. This
provides a shell like interface for querying and managing the dataservice
and includes shell-like features such as command history and editing.
Commands can be executed using cctrl either
connect to 'alpha@host1'
alpha: session established
[LOGICAL:EXPERT] /alpha >
Or by supplying a command and piping that as input to the
echo 'ls' | cctrl
