# Tools
|
|
|
|
ActiveMQ ships with several helpful command line tools. All tools are
|
|
available from the activemq-tools-\<version\>-jar-with-dependencies.jar.
|
|
As the name suggests, this Java archive contains ActiveMQ along with all
|
|
of its dependencies. This is done to simplify the execution of the tools
|
|
by eliminating the need so specify a classpath. These tools are:
|
|
|
|
- **`print-data`**. Used for low-level inspection of the bindings and
|
|
message journals. It takes two parameters - `bindings-directory` and
|
|
`journal-directory`. These are the paths to the directories where
|
|
the bindings and message journals are stored, respectively. For
|
|
example:
|
|
|
|
java -jar activemq-tools-<version>-jar-with-dependencies.jar print-data /home/user/activemq/data/bindings /home/user/activemq/data/journal
|
|
|
|
- **`print-pages`**. Used for low-level inspection of paged message
|
|
data. It takes two parameters - `paging-directory` and
|
|
`journal-directory`. These are the paths to the directories where
|
|
paged messages and the message journals are stored, respectively.
|
|
For example:
|
|
|
|
java -jar activemq-tools-<version>-jar-with-dependencies.jar print-pages /home/user/activemq/data/paging-directory /home/user/activemq/data/journal
|
|
|
|
- **`export`**. Used for exporting all binding and message data
|
|
(including paged and large messages) as well as JMS destinations and
|
|
connection factories (including JNDI bindings). The export is
|
|
structured as XML. This data can then be imported to another server
|
|
even if the server is a different version than the original. It
|
|
takes 4 parameters:
|
|
|
|
- `bindings-directory` - the path to the bindings directory.
|
|
|
|
- `journal-directory` - the path to the journal directory.
|
|
|
|
- `paging-directory` - the path to the paging directory.
|
|
|
|
- `large-messages-directory` - the path to the large-messages
|
|
directory.
|
|
|
|
Here's an example:
|
|
|
|
java -jar activemq-tools-<version>-jar-with-dependencies.jar export /home/user/activemq/data/bindings-directory /home/user/activemq/data/journal-directory /home/user/activemq/data/paging-directory /home/user/activemq/data/large-messages
|
|
|
|
This tool will export directly to standard out so if the data needs
|
|
to be stored in a file please redirect as appropriate for the
|
|
operation system in use. Also, please note that the `export` tool is
|
|
single threaded so depending on the size of the journal it could
|
|
take awhile to complete.
|
|
|
|
- **`import`**. Used for importing data from an XML document generated
|
|
by the `export` tool. The `import` tool reads the XML document and
|
|
connects to a ActiveMQ server via Netty to import all the data. It
|
|
takes 5 parameters:
|
|
|
|
- `input-file` - the path to the XML file generated by the
|
|
`export` tool.
|
|
|
|
- `host` - the IP address or hostname of the server where the data
|
|
should be imported.
|
|
|
|
- `port` - the port where ActiveMQ is listening.
|
|
|
|
- `transactional` - a `boolean` flag to indicate whether or not to
|
|
send all the *message* data in a single transaction. Valid
|
|
values are `true` or `false`.
|
|
|
|
- `application-server-compatibility` - a `boolean` flag to
|
|
indicate whether or not JNDI bindings need special treatment to
|
|
account for the way JBoss AS7, Wildfly, and JBoss EAP 6 handle
|
|
JNDI for remote clients. Each of these application servers
|
|
require a special JNDI binding to allow access from remote
|
|
clients. If this is `true` then every JNDI binding in the XML
|
|
will be duplicated in the "java:jboss/exported/" namespace thus
|
|
allowing both local and remote clients to use the same name when
|
|
accessing resources via JNDI. Valid values are `true` or
|
|
`false`.
|
|
|
|
Here's an example:
|
|
|
|
java -jar activemq-tools-<version>-jar-with-dependencies.jar import /home/user/exportData.xml 127.0.0.1 61616 false false
|
|
|
|
Like the `export` tool the `import` tool is single threaded so
|
|
depending on the size of the XML file it may take awhile for the
|
|
process to complete.
