Usage
ultra <command> [options]
  Commands:
    export <target-jar-file>    Export ultra classes to given jar file
    import <source-jar-file>    Import ultra classes from given jar file
    list                        List all ultra classes in the system

  Options:
    -v --verbose                Output verbose
    -h --historic-only          Filter out only historic ultra classes

When you make changes to an ultra format, historic formats are stored on the system. However, these are not included when you perform a system export. You can use the ultra command to export both current and historic ultra formats from one system and import them as historic formats in another. This is useful when the target system must be able to handle, for example, persisted runtime data that is consistent with a previous version of an Ultra format.

Commands

CommandDescription

export

Use the export command to write Ultra formats on the system to disk. These will be stored in a JAR file that contains the Ultra class definitions. 

Example - Exporting Ultra formats

ultra export /home/user/mz/ultra/ultraexport.jar

Note!

The export command cannot overwrite an existing export file.

import

Use the import command to import Ultra formats from disk. For each Ultra format (class) in the specified JAR file, the command will perform the import if the format is not already present in the Code Server. If a format in the JAR file is historic or not does not matter during import, since it will be considered historic in the target system.

Example - Importing Ultra formats

ultra import /home/user/mz/ultra/ultraexport.jar
list

Use the list command to list Ultra formats on the system.

Example. Listing Ultra formats

$ ultra list

Note!

If an empty list field disappears when the ascii encodes, you need to set a system property called mz.ultra.terminator.backcomp. If set to true, empty list fields do not disappear and backward compatibility is preserved if needed.

To set this up, do the following:

  • Set the config property “mz.ultra.terminator.backcomp” to “true” in platform.xml
  • Restart the platform
  • Regenerate Ultra formats - for more information see  regenerateconfigs(4.0)
  • Re-run the workflow

Options

OptionDescription
[ -v --verbose ]
