Server handling

The administrative command-line interface

The nevismeta command-line interface integrates the op and sudo command-line tools. It consists of several commands.


Instances can be managed by adding an instance name as parameter to the nevismeta command, for example:

# nevismeta instance1 start

If no instance is explicitly specified, the nevismeta command manages the default instance.

Setting up servers

The instance commands are used to install new server instances. There is a "default" instance for easy installation. Other or additional instances need to be configured by providing setup parameters.

nevismeta inst

This command lists the names of all configured server instances.

nevismeta inst create <instancename>

A new server instance is set up by entering the following command:

# nevismeta inst create default

The newly created instance will be deployed on port 8996.

Setup parameters may be provided on the command-line or by passing a setup property file:

# nevismeta inst create default /tmp/

nevismeta inst remove <instancename>

This command removes all files related to the specified instance.

nevismeta inst exists <instancename>

This command is used by configuration scripts to query for already installed server instances.

Controlling the server

nevismeta start

Before starting the nevisMeta server, the command nevismeta start checks whether the server is not already running. If the server is already running, the command only provides status information.

The startup procedure may look as follows:

nevismeta start
nevismeta: Starting nevismeta.
Starting standalone instance 'nevismeta' ..
Status : UP
Instance : nevismeta
Process ID : 51788
Ownership : nvauser / nvbgroup
Filedescriptors : 1024

nevismeta stop

To shut down a running server, the command nevismeta stop terminates all running processes. The display may therefore look as follows:

nevismeta stop
nevismeta: Stopping nevismeta.
Stopping standalone instance 'nevismeta' ..
Status : DOWN
Instance : nevismeta
Process ID : 0
Ownership : --- / ---
Network port(s) : ---
Filedescriptors : 1024

nevismeta restart

This command performs a nevismeta stop followed by a nevismeta start. It may be used as a convenient way to restart nevisMeta after applying configuration changes.

Retrieving status information

nevismeta status

This command displays basic information on the server's current runtime state.

A server that is running displays the following output:

nevismeta status
Status : UP
Instance : nevismeta
Process ID : 51788
Ownership : nvauser / nvbgroup
Network port(s) :
Filedescriptors : 1024

Configuration editing

The configuration files are located in the following directory:


To apply changes to the configuration, a restart of the nevisMeta server is required. See the chapter:nevismeta restart.

nevismeta config

The command nevismeta config opens the main configuration file for editing in a console editor.

Parameter nameDefaultDescription
fileimportsize5242880Maximum size of importable files in bytes.For example, "5242880" means 5 MB.
maxCacheDuration600Maximum cache duration for REST interface responses in seconds.For example, "600" means 10 min.
module.oauthv2.import.regenerate.clientsecretfalseRegenerates client secrets when importing OAuthV2 client entities. {true | false}
expiredDataCleaningInterval3600Interval after which expired data will be cleaned, in seconds. For example, "3600" means 60 minutes or one hour. the truststore file to use for Ninja to parse the SecToken. how Ninja gets the user ID from the SecToken. how Ninja gets user role from the SecToken. SecToken roles to groups or to role principals. Syntax: group | role Recommended setting: "group". See also chapter Configuration of the Web Application in the Ninja reference guide.

For more details, see chapter User ID and Roles in the Ninja reference guide.

nevismeta config env

The command nevismeta config env opens the configuration file env.conf for editing in a console editor. Some plugged components may require additional environment information. This is configured by adding entries to the config file as follows:


The following aspects are configured here:


Package handling

As a rule, the delivered packages use unversioned links to the latest installed software version to reference required binaries without having to specify an exact version. The following command displays these links:

ls -l /opt/nevismeta

Use the nevismeta version command to display the installed version of nevisMeta.
