usage: topo <subcommand> <options>

This command is used to register containers in STR and to create, update, remove, and view pico configurations.

Note!

This command is valid only for the MZ_HOME owner.

When you make changes in pico configurations using topo, these are automatically validated before they are copied to the active registry.

If the command and its arguments can be parsed but fail the validation, you can update the configuration or use a reset command to undo the changes. An error message will appear if the validation fails. You can disable the validation by using the option --no-activation. Changes performed by the mzsh topo will then remain in the master registry until you submit a separate topo activate command.

You can use the following subcommands with topo:

activate
container
convert
diff
env
get
hash
help
migrate
open
rebase-configs
register
reset
set
setupremote
show
unset

The option --allow-disconnected is available for all subcommands except for setupremote. You should only include this option when the Platform is unreachable and you want to use cached data.

activate

Usage: topo activate [--dry-run] [-v, --verbose]

Use topo activate to move staged changes in the master registry to the active registry.

Option	Description
[--dry-run]	Use this option to validate the staged changes without performing the activation.
[–hash <hash value>]	Compare the provided hash value with the actual hash that represents the current state of active registry. The activation fails if the values are not equal. For further information, see hash below,
[-v, --verbose]	Use this option for detailed information about the changes.

Hint!

The options --dry-run and --verbose are useful to learn the mzsh topo syntax. When you have edited the configuration manually, use the following command, to view the corresponding edits in a scripted syntax:

$ mzsh topo activate --dry-run --verbose

Example - Output from activate with verbose Option

$ mzsh topo activate -v --dry-run
mzsh topo set topo://container:main1/pico:ec1/val:config.properties.ec.httpd.port 9096  # (was: 9092)
Dry-run: Validation successful
Dry-run: Stopping without performing activation
Dry-run: Active registry not changed

You can then restore the master registry with the the command mzsh topo reset.

Example - Restart the picos to apply the changes

Changes to the STR are not applied on running pico instances or services. If you, for example, have updated the properties of the Platform and an EC, both must be restarted after activation.

Example, after an mzsh topo activate of ec5, mzsh shutdown and startup needs to be done to apply the changes.

$ mzsh shutdown ec5
$ mzsh startup ec5

container

Usage: topo container

Use topo container to display the name of the current container.

Option	Description
[--allow-disconnected]	Use this option when the Platform is unreachable and you want to operate on cached data.

convert

Usage: topo convert [-c, --container <container>] [-g, --container-group <container group>] [--dry-run] [-f, --file <filename>]

Use topo convert to move the configuration of a specific XML file to STR.

Option	Description
[-c, --container <container>]	Use this option to specify a target container.
[-g, --container-group <container group>]	Use this option to specify a target container group.
[--dry-run]	Use this option to validate that the conversion and display the result of the conversion without updating the STR.
[-f, --file <filename>	Use this option to specify the source XML file.

Example - Converting an XML File

$ mzsh topo convert --container main1

diff

Usage: topo diff [-e, --show-entries] [-f, --from <registry>] [-q, --brief]

Use topo diff to view differences between the master repository and the active repository in the STR.

Option	Description
[-e, --show-entries]	Use this option for viewing differences in an easy-to-read format. By default, the output from the command displays `topo set` commands that correspond to the staged changes. Example - Output from diff Command With -e option: UPDATE (containers/main1/picos/ec1.conf) config.properties.aaa:"2" # (was: "1") Without -e option: mzsh topo set topo://container:main1/pico:ec1/val:config.properties.aaa "2" # (was: "1")
[ -f, --from] <registry>	Use this option when you want to compare the active registry with the backup registry
[-q, --brief]	Use this option to only view the names of the updated registry files. The default value is false.

Example - Comparing Registry Files

Run the following command to view the differences between the active registry and the master registry.

$ mzsh topo diff

or

$ mzsh topo diff --from master

Run the following command to view the differences between the active registry and the backup registry.

$ mzsh topo diff --from backup

env

Usage: topo env [-e, --effective] [--update-java-home <value>] [--update-mz-container <value>] [--update-mz-home <value>] 
[--update-mz-platform <value>]

Use topo env to display or set environment variables that are used by the mzsh command. These variables are written to the script file MZ_HOME/bin/mzsh.
The variables, MZ_PLATFORM, MZ_CONTAINER and MZ_CONTAINER_TYPE, are handled differently than the rest. To update the value in the script file you use the parameters starting with --update-<value> as per the below table. To update the value in the script file and use the value immediately, you need to combine the --update-<value> parameter with the -e parameter.

Option	Description
[-e, --effective]	Use this option to read the environment parameters in runtime, i e the "effective values" after accounting for overrides. The default behaviour is to read the values as they are defineds in the mzsh script file, not accounting for the possibility to override these values with environment variables.
[--update-java-home <value>]	Use this option to update the value of JAVA_HOME
[--update-mz-container <value>]	Use this option to update the value of MZ_CONTAINER.
[--update-mz-home <value> ]	Use this option to update the value of MZ_HOME.
[--update-mz-platform <value> ]	Use this option to update the mzsh value of MZ_PLATFORM.

Example - Reading the Environment Variables

$ mzsh topo env
export JAVA_HOME="/opt/Java/JavaVirtualMachines/jdk-17.0.2.jdk/Contents/Home"
export MZ_CONTAINER="main1"
export MZ_CONTAINER_TYPE="platform"
export MZ_PLATFORM="http://localhost:9000"
export MZ_HOME="/user/home/mz/main1"

Example - Setting the Environment Variable JAVA_HOME

$ mzsh topo env --update-java-home /opt/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home

get

Usage: topo get [--default-val <value>] [ --exclude-dynamic] [--format <full | data-only>] [-l, --local] [-p, --perspective] <target path>]

Use topo get to retrieve pico configurations in the target path from STR.

Paths in STR are structured as follows:

topo://container:<container>/pico:<pico>/val:<attribute>

Option	Description
[--default-val <value>]	Use this option to replace a missing value in the target path with a default value. Example - Using default-val If the property aaa, is not defined for ec1, 123 is returned instead. $ mzsh topo get -l --default-val 123 \ topo://pico:ec1/val:config.properties.aaa
[ --exclude-dynamic]	Use this option to exclude non-static data in the output e g `_status` in a pico configuration. This is useful in case of errors that blocks the topo command.
[--format <full\|data-only>]	Use this option to exclude metadata from the command output. full - Include meta data data-only - exclude meta data Default: `full`
[-l, --local]	Use this option to select the local container, unless another container is specified in the target path. Default: `false`
[-p, --perspective <resolve \| default>]	Use this option to retrieve the attributes of templates instead of the template names. resolve - attributes default - template names Default: `default`

Example - Viewing Pico Configurations

Run the following command to view one or more pico configurations.

$ mzsh topo get topo://container:main1/pico:ec2

You can view multiple pico configurations by replacing the full path with a regular expression.

$ mzsh topo get topo://container:main1/pico:.*

Example - Viewing Pico Attributes

Run the following command to view a specific attribute in a pico configuration.

$ mzsh topo get topo://container:main1/pico:ec2/val:_name

You can retrieve the attributes of multiple pico processes by replacing the full path with a regular expression.

$ mzsh topo get --format data-only topo://container:main1/pico:.*/val:_name

hash

 Usage: topo hash

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

Example - Using Hash Values

Application 1 retrieves a new hash value.

$ mzsh topo hash 
"3a2e373fa1653c7f0e757e2682c70317-2028777631"

Application 1 retrieves the properties of ec1.

$ mzsh topo get -l pico:ec1/obj:config.properties

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.
```
$ mzsh topo set -l --no-activation --hash 3a2e373fa1653c7f0e757e2682c70317-2028777631 \ 
topo://pico:ec1/val:config.properties.ec.httpd.port 9090 
```

Application 2 updates the properties of ec1. The hash value is updated.

$ mzsh topo set -l topo://pico:ec1/val:config.properties.ec.httpd.port 9090

Application 1 calls topo activate with hash value retrieved in step 1.

$ mzsh topo activate --hash 3a2e373fa1653c7f0e757e2682c70317-2028777631

The activation fails since the hash values do not match.

Specified hash does not match transaction id:  d9cd38f3793647028bd7e5d64c354ad5-2055434210 != 3a2e373fa1653c7f0e757e2682c70317-2028777631)
This may indicate concurrent modification of registry: Operation aborted!

Application 1 resets the master registry, retrieves a new hash and starts over.
```
$ mzsh topo reset
$ mzsh topo hash 
```

help

Usage: topo help [<subcommand>]

Use topo help to retrieve a description of a subcommand.

Run the following command for an overview of the various topo subcomands

$ mzsh topo help

Run the following command for a description of a specific subcomand

$ mzsh topo help <command>

migrate

Usage: topo migrate

Use topo migrate to move pico configurations from MZ_HOME to STR. The upgrader runs this command during upgrade to 8.0.

open

Usage: topo open [-n, --no-activation] <target path>

Use topo open to open a cell, container- or pico configuration file in a text editor. When you save and close the editor, the command will call topo activate to move the staged changes in the master registry to the active registry.

Option	Description
[-n, --no-activation]	Use this option to skip activation after changes in master registry.

Run the following command to open a cell configuration:

$ mzsh topo open cell:<cell>

Example - Opening a Cell Configuration

$ mzsh topo open cell:default

Run the following command to open a container configuration:

$ mzsh topo open <container>

Example - Opening a Container Configuration

$ mzsh topo open main1

Run the following command to open a pico configuration:

$ mzsh topo open <pico>

Example - Opening a Pico Configuration

$ mzsh topo open ec1

or

$ mzsh topo open container:main1/pico:ec1

If the pico name is not unique in the system, you will be prompted to specify the container.

Example - Multiple Pico Configurations Sharing the Same Name

$ mzsh topo open ec2 (/home/main1/common/config/cell/default/master/containers/main1/picos/ec2.conf,ec2,topo://container:main1/pico:ec2)
(/home/main1/common/config/cell/default/master/containers/exec1/picos/ec2.conf,ec2,topo://container:exec1/pico:ec2)

Multiple entries, select one:
 (1) topo://container:main1/pico:ec2
 (2) topo://container:exec1/pico:ec2
 [1] :

To avoid ambiguous references, specify the name of the container and the pico configuration.

Run the following command to open the custom or the standard services configuration:

$ mzsh topo open services:<custom|standard>

Example - Opening a Service Configuration

$ mzsh topo open services:custom

Hint!

When you save the configuration, topo activate is called with the --verbose option and the saved changes are displayed in a scripted syntax.

By default, the command opens the vi editor. To use a different editor set the environment variable EDITOR.

Example - Setting nano as the Default Editor

$ export EDITOR=nano

rebase-configs

Usage: topo rebase-configs [-a, --activate] <target path>

Use topo rebase to inset a standard template in a pico configuration and remove attributes that are identical to attributes in the template. The command automatically detects the pico configuration type and applies one of the following templates:

mz.standard-platform.conf
mz.standard-ec.conf
mz.standard-sc

This command is useful to reduce the size of the pico configurations and thereby facilitate maintenance.

The changes are written to the master registry. To validate and activate the changes you can either use the --activate option or run topo activate after the topo rebase-configs command.

For further information about templates, see STR File Structure.

Option	Description
[-a, --activate]	Use this option to immediately activate after changes in master registry.

Example - Rebasing an EC Configuration

$ mzsh topo rebase-configs topo://container:main1/pico:ec1$ mzsh topo active --verbose

or

mzsh topo rebase-configs --actoivate topo://container:main1/pico:ec1

register

Usage: topo register [-a, --address] [-c, --container] [-g, --container-group <container group>] [--mz-home <mz home>] [-u]

When you install an execution container, and the Platform is running, it is automatically registered in the Platform Container. If the platform is not running during the installation, use topo register to register the Execution Container manually.

Option	Description
[-a, --address <ip/host>]	Use this when you need to set a different host address for the container than the one that is specified in the common property `pico.rcp.server.host`, which is the default value. This option is typically used together with the `-u` option.
[-c, --container <container>]	Use this option when you need to change the existing container name. This option is typically used together with the `-u` option.
[-g, --container-group <container group>]	Use this option when you need to change the existing container group. This option is typically used together with the `-u` option.
[--mz-home <path>]	Use this option when you need to set a different home directory for the container than the one that is specified in the environment variable MZ_HOME, which is the default value.
[-u]	Use this option to allow updates of an already registered container. By default, updates are not allowed and the command will attempt to register a new container.

reset

Usage: topo reset

Use this option to remove any changes to the master registry in STR since the activation

set

Usage: topo set [-l, --local] [-n, --no-activation] [-s, --strict-json] <target path> <config>

Use topo set to create and update 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.
[--no-activation, -n]	Use this option to skip activation after changes in master registry.
[-s, --strict-json]	Use this option when you want to specify the configuration in JSON format instead of HOCON format.

Run the following command to create a new pico configuration.

$ mzsh topo set topo://container:<container>/pico:<pico> <config>

The <config> argument may contain a key-value pair that specifies a template or a pico configuration in HOCON format.

Example - Creating a New Pico Configuration Based on a Template

 $ mzsh topo set topo://container:main1/pico:ec2 template:mz.standard-ec

Example - Creating Pico Configuration

When you specify a pico configuration that consists of multiple attributes, it is recommended that you use multi-line strings.

HOCON Format:

$ mzsh topo set --local pico:ec2 '
{
	template:mz.standard-ec
	config {
		properties {
			ec.httpd.port : 9092
		} 
		classpath {
			jars=["lib/picostart.jar"]
		}
	}
}'

JSON Format:

mzsh topo set -l --strict-json pico:ec2 '
{
	"template": "mz.standard-ec",
	"config": {
		"properties": {
			"ec": {
				"httpd": {
					"port": 9092
				}
			}
		},
		"classpath": {
			"jars": ["lib/picostart.jar"]
		}
	}
}'

Add the pico group setting by using the following topo command

mzsh topo set topo://container:main1/pico:ec1/val:config.properties.pico.groups "ec1, ec2"

This command makes the Execution context "EC1" a member of the "ec1" and "ec2" groups.

This is the HOCON example format adding in ECs to a pico group.

config {
    classpath {}
    jvmargs {
        args=[]
    }
    properties {
        mz.webserver.xframeoptions=DENY
        pico.groups="ec1, ec2"
        ec.backlog.dir="/home/davids/git/mz9/mediationzone/mz-dist/../mzhomes/mz9/tmp"
        ec.webserver.port=9137
    }
    vendor-jvmargs {
        hp {}
        sun {}
    }
}

Run the following command to add or update an attribute of a pico configuration.

mzsh topo set topo://container:<container>/pico:<pico>/val:<attribute> <attribute value>

Example - Updating a Pico Attribute

$ mzsh topo set topo://container:main1/pico:ec2/val:ec_type ec

Run the following command to add or update an object that contains one or more attributes.

$ mzsh topo set topo://container:<container>/pico:<pico>/obj:<object name> '<config>'

The <config> argument may contain a pico configuration in HOCON format.

Example - Updating a Pico Object

This command adds the properties value1 and value2:

$ mzsh topo set topo://container:main1/pico:ec2/obj:config.properties.example_object '{
 value1=1
 value2=2
}'

The following commands does not overwrite the properties value1 and value2 in example_object but adds value3:

$ mzsh topo set topo://container:main1/pico:ec2/obj:config.properties.example_object '{
 value3=3
}'

setupremote

Usage: topo setupremote [-c, --container <container>] [-g, --container-group <container group>] [--host-key <path>] [--javahome <path>] [--no-authorized-key] [--no-host-key] [-- no-ssh-details] [--ssh-address <ip/host>] [--ssh-port <port>] [--ssh-username <username>]

Use the command topo setupremote to enable remote access via SSH to an Execution Container, e g from the Platform container.

Option	Description
[-c, --container <container>]	Use this option to specify a different container than the local one, which is the default value.
[-g, --container-group <container group>]	Use this option to setup remote access to a container in specific container group. This is useful when you have multiple containers with identical names in different containers groups.
[--host-key <path>]	Use this option to use a pre-generated host key instead of the one that is generated when you run `topo setupremote`.
[--java-home <path>]	Use this option when the target container is located on a different host. The default value is specified by the environment variable JAVA_HOME in the current shell.
[--no-authorized-key]	By default, the `topo setupremote` command will obtain a public authorization key from the user home directory on the Platform Container host and store it in the STR, i e the file `mz.conf`. Use the option `--no-authorized-key` to skip this operation.
[--no-host-key]	By default, the `topo setupremote` command will store the public host key of the Execution Container in the STR, i e the file `mz.conf`. Use the option `--no-host-key` to skip this operation.
[--no-ssh-details]	Use this option to exclude `ssh-username` and `ssh-address` from STR. These attributes are required for remote access. If you use this option you will need to update the STR manually.
[--ssh-address <ip/host>]	Use this option when the target container is located on a different host or when you want to bind to a specific IP address or hostname. The default value is specified by the `address` attribute for container in `mz.conf`.
[--ssh-port <port>]	Use this option when you want to use a different port than 22 for SSH.
[--ssh-username <username>]	Use this option when the target container is located on a different host or when a specific username is required for SSH. The default SSH user is the OS user that runs the `topo setupremote` command.

show

Use topo show to retrieve various types of information about pico instances that are defined in the STR.

Usage: topo show [ --exclude-dynamic] [--format <format>] [-l, --local] [--timeout-seconds <time>] <view>

Option	Description
[ --exclude-dynamic]	Exclude non-static data in the output e g `_status` in a pico configuration. This is useful in case of errors that blocks the topo command.
[ --format <format>]	Set the format of the returned data: csv json table (default)
[ -l, --local ]	Use this option to view pico instances in the local container only. By default, all containers are included.
[--timeout-seconds <time>]	Use this option to limit the time for retrieving dynamic information, e g `_status`.The default value is 10 seconds.

The following views are available:

jvm-args - Displays the JVM arguments that are used by the pico instances in the system. JVM arguments that are set in templates are included.
status - Displays the container name, pico name, pico type and running state.
status-sc - Displays similar view as status but only includes SCs.
status-ec - Displays similar view as status but only includes ECs.
status-long - Displays similar view as status but also includes the status of replication between Platform Container and Execution Containers.
pico-view - Displays similar view as status but also includes memory usage and the pico response time.
pico-view2 - Displays similar view as pico-view but also includes uptime.
ports - Displays the ports that are used by the pico instances in the system. Ports that are set in templates and on cell- and container level, are included. If both webserver and httpd ports are displayed, then webserver ports take precedence.

Example - Views

$ mzsh topo show jvm-args

unset

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>

Example - Removing a Pico Configuration

$ mzsh topo unset topo://container:main1/pico:ec2

Example - Removing a Pico Attribute

$ mzsh topo unset topo://container:main1/pico:ec2/val:ec_type ec

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.

Example - Resolved Path

$ 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

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

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 activation.

Example - Handling Conflicting Attributes, Manual Editing

common : {
    "pico.rcp.tls.keystore" : "home/mz/keys",
    "pico.rcp.tls.keystore.password" : "..."
}

When there are conflicting properties and you are using the mzsh topo command, also add single quotes, surrounding the target path (topo://..).

Example - Handling Conflicting Attributes, Scripted Editing

$ mzsh topo set 'topo://container:<platform container>/val:common."pico.rcp.tls.keystore"' "home/mz/keys"
$ mzsh topo set 'topo://container:<platform container>/val:common."pico.rcp.tls.keystore.password"' "..."

Updating IP, Hostname, and Ports in JDBC URL

You can update the IP address, hostname, and ports int he JDBC URL using the mzsh topo get and mzsh topo set commands as shown in the examples below.

Example - Get Current Config

$ mzsh topo get -s --format data-only topo://container:platform1/pico:platform/obj:config.properties.mz.jdbc
	{
		"password": "DR-4-48851644227183C2041D838568E117EC",
		"oracle": {
		"ons": ""
		},
		"type": "oracle",
		"user": "mzadmin",
		"url": "jdbc:oracle:thin:@//127.0.0.1:1521/orcl"
	}

Example - Update URL with set

$ mzsh topo set topo://container:mz/pico:platform/val:config.properties.mz.jdbc.url "jdbc:oracle:thin:@//192.168.1.10:1522/orcl"

[ set: topo://container:mz/pico:platform/val:config.properties.mz.jdbc.url => jdbc:oracle:thin:@//192.168.1.10:1522/orcl] 
Updating file: $MZ_HOME/common/config/cell/default/master/containers/mz/picos/platform.conf
Topology activation completed (master->active)

Caution!

When you have set the new JDBC URL, run shutdown and startup on the platform to ensure that your changes take effect properly.
If you added the incorrect config and the platform did not start, you can run your mzsh command again with the --allow-disconnected option

Return Codes

Listed below are the different return codes for the topo command:

Code	Description
0	Will be returned if the command is successful.
1	Will be returned if the argument count is incorrect or argument(s) are invalid.
3	Will be returned if the target path argument for the subcommand `get` does not exist.
