3.33 Upgrading Nitro Web Services (RPM)

This topic contains instructions on how to upgrade Nitro Web Services using the RPM upgrade method.

3.33.1 Upgrade Nitro Web Services

On the Nitro Web Services Host, do the following:

If you installed Nitro Web Services on its own host or if Nitro Web Services is the first component being upgraded on a host with other RPM installations, complete the steps to prepare the host. See 3.19 Preparing for RPM Upgrades for more information.
If you are upgrading Nitro Web Services from a version prior to 2.1.0, confirm the MongoDB database is upgraded to 3.2.x. See 3.23 Upgrading to MongoDB 3.2.x (RPM) for more information.

Stop the services.

[root]# service nitro-web-services stop
[root]# service nitro-zmq-job-status-adapter stop

If you are upgrading Nitro Web Services from 2.0.0, re-enable the services.

[root]# chkconfig nitro-web-services on
[root]# chkconfig nitro-zmq-job-status-adapter on

If you have customized your configuration files, the RPM upgrade will have copied the new configuration files into the /opt/nitro-web-services/etc directory with a .rpmnew extension. Merge any parameter changes in the .rpmnew files into the respective configuration files.
See the step "Understand and edit the configuration files." in 3.16.3 Install and Configure Nitro Web Services for more information on the configuration files.

Restart the services.

[root]# service nitro-web-services start
[root]# service nitro-zmq-job-status-adapter start

3.33.2 Grant Users Nitro Permissions in Viewpoint

Verify that the users who work with Nitro Web Services have the appropriate role in their Viewpoint user principal.

These are the Viewpoint roles for Nitro:

NitroAdmin – Administrative user, with permission to create Nitro application templates and manage other user's Nitro jobs.
NitroUser – Basic user, with permission to create and manage their own Nitro jobs.

See Creating or Editing Principals in the Moab Viewpoint Reference Guide for instructions on setting up principals.
