Tungsten Cluster™ 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 interface.

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 the 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 example, /opt/continuent/share/env.sh. To load into the current session use source. See "Establishing the Shell Environment" for more information.

shell> source /opt/continuent/share/env.sh

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 interactively:

shell> cctrl
connect to 'alpha@host1'
alpha: session established
[LOGICAL:EXPERT] /alpha > ls

Or by supplying a command and piping that as input to the cctrl shell:

shell> echo 'ls' | cctrl
