OCSS7 2.2.0 :: OCSS7 Installation and Administration Guide

What is the SGC Stack Command-Line Console?

The SGC Stack Command-Line Management Console is a CLI tool working in interactive and non-interactive mode to manage and configure the SGC Stack cluster. The Command-Line Console uses JMX Beans exposed by the SGC Stack to manage cluster configuration. The command syntax is based on ITU-T MML Recommendations Z.315 and Z.316.

Installation and requirements

Command-Line Console installation requires unpacking the tar.gz archive file in any location. Unpacked, the folder structure is:

File/Directory Description

File/Directory	Description
`.`	SGC CLI installation directory
`./conf`	logging configuration and CLI settings file
`./lib`	Java libraries used by SGC CLI.
`./log`	log file
`./sgc-cli.sh`	CLI start-up script

.

SGC CLI installation directory

./conf

logging configuration and CLI settings file

./lib

Java libraries used by SGC CLI.

./log

log file

./sgc-cli.sh

CLI start-up script

JAVA_HOME

The SGC CLI start-up script expects the JAVA_HOME environment variable to be set up and point to a valid Java Virtual Machine version 7 or greater (it expects executable file JAVA_HOME/bin/java).

Working with the SGC CLI

The SGC CLI should be started by executing the sgc-cli.sh script. Default connection settings point to the SGC JMX Server exposed at:

host: 127.0.0.1
port: 10111

Here is an example of starting the CLI with the default IP and port:

./sgc-cli.sh

Here is an example of starting the CLI with an alternative IP and port setup:

./sgc-cli.sh -h 192.168.1.100 -p 10700

The SGC CLI supports other configuration parameters, which you can display by executing the startup script with the -? or --help options:

usage: sgc-cli.sh [-?] [-b <FILE>] [-h <HOST>] [-P <PASSWORD>] [-p
       <PORT>] [-stopOnError <true/false>] [-U <USER>] [-x <FILE>]
+-----------------------------Options list-----------------------------+
 -?,--help                                 Displays usage
 -b,--batch <FILE>                         Batch file
 -h,--host <HOST>                          JMX server user
 -P,--pass <PASSWORD>                      JMX password
 -p,--port <PORT>                          JMX server port
 -ssl,--ssl <true/false>                   JMX connection SSL enabled
 -stopOnError,--stopOnError <true/false>   Stop when any error occurs in
                                           batch command
 -U,--user <USER>                          JMX user
 -x,--export <FILE>                        File where the configuration
                                           dump will be saved
+----------------------------------------------------------------------+

Enabling secured JMX server connection

CLI supports secured JMX server connection through the SSL protocol (SSL). It can be enabled in two ways:

by specifying the ssl=true property in conf/cli.properties,
by adding the configuration parameter -ssl true to the start script.

The configuration parameter value takes precedence over the value defined in conf/cli.properties.

The SSL connection (in both cases) also requires specifying additional properties in the conf/cli.properties file, for the trustStore, keyStore password and location. Below is a sample configuration:

#######################
###SSL configuration###
#######################

#File location relative to conf folder
javax.net.ssl.keyStore=sgc-client.keystore
javax.net.ssl.keyStorePassword=changeit

#File location relative to conf folder
javax.net.ssl.trustStore=sgc-client.keystore
javax.net.ssl.trustStorePassword=changeit

Basic command format

The command syntax is based on ITU-T MML Recommendations Z.315 and Z.316:

command: [parameter-name1=parameter-value1][,parameter-name2=value2]…;

Where:

command is the name of the command to be executed
parameter-name is the name of command parameter
parameter-value is the value of the command parameter.

Command parameters are separated by commas (,).

When specifying a command with no parameters, the colon (:) is optional.

The ending semicolon (;) is optional.

MML syntax auto-completing

The CLI supports MML syntax auto-completing on the command name and command parameters level. Pressing the <TAB> key after the prompt will display all available command names:

When you press the <TAB> key after providing a command name, the CLI displays all available parameters for that command.

Pressing <TAB> after providing command parameters displays legal values (for enumeration, reference, and boolean parameters). For example:

SGC[127.0.0.1:10111]> modify-connection: <TAB_PRESSED>
oname=A-CONN-1        oname=B-CONN-1
SGC[127.0.0.1:10111]> modify-connection: oname=

Help mode

You can access the SGC CLI’s built in help system by either:

executing the command help: topic=topicName
switching to help mode, by executing the manual help command (with no parameters).

Help mode displays topics that you can access. (Alternatively, you can press the <TAB> to display available values of a topic command parameter. The list of available topics in manual help mode looks like this:

SGC[127.0.0.1:10111]> help
Executing help manual...
Use <TAB> to show topic list. Write 'topic name' to see its description. Use exit command if you want to quit the manual.
Hint: 'create-, display-, remove-, modify-, enable-, disable-' operations are described by single topic for given MBean name.
Available topics:
as                             as-connection                  as-precond                     batch                          clear-active-alarm             clear-all-alarms

The result of executing a help topic command looks like this:

Interactive mode

By default, the CLI starts in interactive mode, which lets the System Administrator execute commands and observe their results through the system terminal. For example, here’s a successfully executed command:

SGC[127.0.0.1:10111]> display-info-healthinfo: ;
Found 1 object(s):

Here’s an example of a command that failed:

ERROR REMOVE_OBJECT_FAILED: Instance 'SGC:category=conn-ip,type=m3ua,id=invalidName' doesn't exist.

Command result truncation

CLI supports the truncation of command result (cell data) to make the output more convenient (In case of large cell data). This configuration property is defined in the conf/cli.properties file. Following is the property:

table.format.maxCellContentLength=40
