epadmin

StreamBase Runtime — StreamBase Runtime command

SYNOPSIS

epadmin [global-parameters] [command] [target] [target-parameters]

epadmin
 help [target]

DESCRIPTION

Use the epadmin command to install, start, manage, and communicate with StreamBase Runtime nodes and clusters. Use epadmin from a configured shell prompt as follows:

The components of an epadmin command are:

  • global-parameters are one or more parameter statements from the short list of global parameters that can apply to any epadmin command and target. Run epadmin help globals for the list.

  • command is an imperative verb such as display, install, start, stop, and help that is to be applied to the target.

  • target is one of the supported targets for the command to act on, such as node, cluster, application, engine. Run epadmin help targets for the list of supported targets.

  • target-parameters is one or more parameter statements from the list of parameters supported by the specific command and target. Use epadmin help targetname to see the target-parameters available for that target.

Parameter Syntax

The epadmin command supports two syntaxes for entering parameters:

  • Gnu-style parameter syntax with two hyphens prefixing parameter names. You can enter the fewest number of letters of each parameter's name that maintains that parameter's uniqueness among the current target's supported parameters. For example, the following two lines perform the same action: 

    epadmin --adminport=2000 --username=sbuser --password=secret display node
epadmin --ad=2000 --us=sbuser --pa=secret display node

  • Legacy syntax from previous releases is still supported. In this format, parameters do not use prefixed hyphens, and you must type the full parameter name. For example: 

    epadmin adminport=2000 username=sbuser password=secret display node

You cannot mix old and new syntax in the same command.

Help System

The epadmin command has extensive built-in usage help. Enter epadmin help for the help starting point. Use epadmin help targetname to see target-specific help.

The epadmin help node command is especially useful to remind you of the syntax to install and start nodes.

In previous StreamBase releases, calling epadmin help required connecting to an installed node. Starting with StreamBase 10.3.0, epadmin help is available offline, without nodes or clusters running.

The full syntax of the epadmin command is described in its help system, or in a separate documentation page.
