Environment Variables</h1>
<p>The GRAM Job Manager provides a minimal environment for user's jobs. The following environment variables will be set by the job manager. Variables marked with an asterisk (*) will only be set if a related job manager configuration option or RSL attribute is provided. Local schedulers may set additional environment variables.</p>
<dl class="section user"><dt>HOME</dt><dd>The user's home directory.</dd></dl>
<dl class="section user"><dt>LOGNAME</dt><dd>The user's login name.</dd></dl>
<dl class="section user"><dt>X509_USER_PROXY</dt><dd>The path to the job manager's delegated credential. (GSI only).</dd></dl>
<dl class="section user"><dt>GLOBUS_GRAM_JOB_CONTACT</dt><dd>The job manager's contact string for this job.</dd></dl>
<dl class="section user"><dt>GLOBUS_LOCATION</dt><dd>The path to the Globus installation on the job manager host.</dd></dl>
<dl class="section user"><dt>X509_CERT_DIR*</dt><dd>The path to a trusted certificate directory. This variable will only be set if the -x509-cert-dir argument is given to the job manager.</dd></dl>

<dl class="section user"><dt>GLOBUS_TCP_PORT_RANGE*</dt><dd>A system-specific range of TCP ports which may be used by the job. Globus I/O will automatically honor this range. Only present if the related configuration option is present in the job manager configuration file.</dd></dl>
<dl class="section user"><dt>GLOBUS_REMOTE_IO_URL*</dt><dd>The path to a file containing a URL string of a GASS server which the job may access (if the remote_io_url attribute is present).</dd></dl>
<dl class="section user"><dt>GLOBUS_NEXUS_NO_GSI</dt><dd>Disables GSI in Nexus's TCP protocol, for compatibility with Nexus 4.6 and earlier.</dd></dl>
<h1><a class="anchor" id="globus_gram_job_manager_rsl_subs"></a>
RSL Substitions</h1>
<p>In addition to the environment variables described above, a number of RSL substitutions are made available by the job manager. These substitions may be added to the environment by the job RSL if needed.</p>
