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

Example - Using hash values

Application 1 retrieves a new hash value.

Code Block

language	text

$ mzsh topo hash 
"3a2e373fa1653c7f0e757e2682c70317-2028777631"

Application 1 retrieves the properties of ec1.
Code Block
language text
$ 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.
Code Block
language text
$ 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.
Code Block
language text
$ 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.
Code Block
language text
$ mzsh topo activate --hash 3a2e373fa1653c7f0e757e2682c70317-2028777631

The activation fails since the hash values do not match.

Code Block

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.
Code Block

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

HOCON Format:

Code Block

language	text

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

JSON Format:

Code Block

language	text

mzsh topo set -l --strict-json pico:ec2 '

		}
	}
}'

Add the pico group setting by using the following topo command

Code Block
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.

Code Block

config {
    classpath {}
    jvmargs {
        args=[]
    }
    properties {
        mz.webserver.xframeoptions=DENY

unset

Code Block
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>

Info

Example - Removing a pico configuration

Code Block

language	text

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

Info

Example - Removing a pico attribute

Code Block

language	text

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

Excerpt

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

language	text

$ 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.

Info

Example - Substituted path

Code Block

language	text

$ 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.

Info

Example - Handling conflicting attributes, manual editing

Code Block
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://..).

Info

Example - Handling conflicting attributes, scripted editing

Code Block

$ 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.

Info

Example - Get current config

Code Block

language	bash

$ 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"
	}

Info

Example - Update URL with set

Code Block

language	bash

$ 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)

Note

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

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.
