Use VOV Subsystem Help

When VOV Subsystem is running, it displays the documentation through its browser interface. To access it from browser, you need to know which host and port VOV Subsystem is running on. Ask your administrator, or find the URL for VOV Subsystem with the following command:

% VOV Subsystem cmd vovbrowser
http://comet:6271/project

In the example below, assume VOV Subsystem is running on host comet, port 6271. The URL for VOV Subsystem is:

http://comet:6271

To get the entire suite of Altair Accelerator documents, including FlowTracer™, Accelerator™, Monitor™ and the VOV subsystem, use the following URL:

http://comet:6271/doc/html/bookshelf/index.htm

All the documentation files are in the Altair Accelerator install directory, so you can access them even if vovserver is not running. To do this, open /installation_directory/common/doc/html/bookshelf/index.htm in your browser.

The main commands of Accelerator are nc and ncmgr, with some subcommands and options. You can get usage help, descriptions and examples of the commands by running the command without any options, or with the -h option. For example,

% nc info -h
nc:
nc:  NC INFO:
nc:  Get information about a specific job or list of jobs.
nc:  USAGE:
nc:  % nc info <jobId> [options]...
nc:   -h      -- Show this message
nc:   -l      -- Show the log file
nc: 

Another source of live information is using the command vovshow. The following options are often useful:

vovshow -env RX

Displays the environment variables that match the regular expression RX provided.

vovshow -fields

Shows the fields known to the version of VOV in use.

vovshow -failcodes

Shows the table of known failure codes.

For example, to find a variable that controls the name of the stdout/stderr files, without knowing the exact name of that variable, the following command can be used:

% vovshow -env STD
VOV_STDOUT_SPEC           Control the names of file used to save stdout and
                          stderr. The value is computed by substituting
                          the substrings @OUT@ and @UNIQUE@ and @ID@.
                          Examples: % setenv VOV_STDOUT_SPEC
                          .std@OUT@.@UNIQUE@ % setenv VOV_STDOUT_SPEC
                          .std@OUT@.@ID@
