Use topo hash to retrieve a value that represents the current state of the active registry. This is useful when you need to handle concurrent changes of the STR. For instance, an application may need to retrieve a pico configuration to evaluate the required changes. In the meantime, a second application or a user may update the same configuration

Info
title

Example - Using hash values

  1. Application 1 retrieves a new hash value.

    Code Block
    languagetext
theme
Eclipse
$ mzsh topo hash 
"3a2e373fa1653c7f0e757e2682c70317-2028777631"

    Code Block
    languagetext
  • themeEclipse
    1. $ mzsh topo get -l pico:ec1/obj:config.properties
    2. Application 1 updates a property but does not call topo activate. The hash is specified to ensure that changes by other users are not activated inadvertently later on.

      Code Block
      languagetext
    theme
    Eclipse
    1. $ mzsh topo set -l --no-activation --hash 3a2e373fa1653c7f0e757e2682c70317-2028777631 \

    Usage: topo unset [-l, --local] [-n, --no-activation] <target path>

    Use topo unset to remove pico configurations in the specified target-path of STR.

    Option

    Description

    [-l, --local]

    Use this option to select the local container, unless another container is specified in the target path.       

    [-n, --no-activation]

    Use this option to skip activation after changes in master registry.

    Run the following command to remove a pico configuration.

    mzsh topo unset topo://container:<container>/pico:<pico>

    File Paths in Attributes

    When you enter a path that is relative to MZ_HOME in the value of an attribute, it is recommend that you use ${mz.home} as a substitution.

    In the following example MZ_HOME will be resolved to its current value e g /home/user/mz.

    Info

    ...

    Example - Resolved path

    Code Block
    languagetext

    ...

    ...

    $ mzsh topo set topo://container:main1/val:common.pico.rcp.tls.keystore $MZ_HOME/keys/platform.keys

    The next example uses a path that is always relative to MZ_HOME.

    Example - Substituted path

    Code Block
    languagetext

    ...

    $ mzsh topo set topo://container:main1/obj:common.pico.rcp.tls.keystore '{ keystore=${mz.home}"/keys" }'

    ...

    titleNote!

    When you are using ${mz.home} as a substitution,

    ...

    ensure to set attributes as part of an object, using the obj keyword.

    Conflicting Attributes

    The name of an attribute may contain the full name of another attribute. For instance, mz.httpd.security.keystore is a system property but its name is also a part of mz.httpd.security.keystore.password.

    In this case you must ensure that the name of both properties are surrounded by quotes, or one of the properties will be overwritten at
