Installing the Model9 management server on zCX


Prepare the environment for installation of the server on zCX by following these steps:

License key

Obtain a license key from Model9 by opening a “new license request” in the Model9 service portal:

The output of the z/OS command “D M=CPU” is required.

zCX Configuration

  1. Verify that the zCX instance has at least 8GB of memory.

  2. Verify that the zCX root filesystem has at least 8GB of storage space.

  3. Verify that the zCX data filesystem has at least 40GB of storage space (Extra data volumes can be added dynamically after instance creation).


  1. Create docker volumes for the Model9 management server and database:

    docker volume create model9
    docker volume create model9db
  2. Create a docker instance of alpine linux to unzip and edit the installation files.

    # Running an alpine container and mounting the model9 docker volume
    docker run -d --rm --name dummy -v model9:/root s390x/alpine \
    tail -f /dev/null
  3. Upload the s390x installation zip to the zCX instance.

  4. Copy the s390x installation zip from the zCX instance to the alpine container (one line):

    docker cp dummy:/root/
  5. Optional: Install bash for advanced file edit capabilities

    docker exec -it dummy sh
    apk update && apk add bash

Step 1: Unzip the installation file

Create the filesystem hierarchy using the following commands:

docker exec -it dummy sh
cd /root
unzip /root/

# Logout of Alpine container (CTRL+D)

Step 2: Copy the containers to the zCX instance

Copy the docker containers from the alpine docker container:

docker cp dummy:/root/model9-v2.0.0_build_f3aba202-s390x.docker ./
docker cp dummy:/root/postgres-s390x-12.3.docker.gz ./

Step 3: Load the docker container to the zCX instance

Create the filesystem hierarchy using the following commands:

docker load -i model9-v2.0.0_build_f3aba202-s390x.docker
docker load -i postgres-s390x-12.3.docker.gz

Step 4: Start the Model9 database container

  1. Start the Model9 PostgreSQL database container using the following command:

    docker run -p \
    -v model9db:/var/lib/postgresql/data:z \
    --name model9db --restart unless-stopped \
    -e POSTGRES_PASSWORD=model9 -e POSTGRES_DB=model9 -d s390x/postgres
  2. Verify the health status of the container and make sure it is ready to accept connections by issuing the following command and verifying its output as shown in the following example:

    docker logs model9db

Step 5: Update the Model9 management server parameters file

Login to the alpine container and edit the model9-local-yml file:

docker exec -it dummy sh
cd /root
vi conf/model9-local.yml
#Logout of Alpine container (CTRL+D)

Some of the parameters are explained below:

model9.licenseKey: <license-key>

model9.home: 'MODEL9_HOME' true 'MODEL9_HOME/keys/model9-backup-truststore.jks' "JKS" "model9" 'MODEL9_HOME/keys/model9-backup-server.p12' "PKCS12" "model9"

model9.session.timeout.minutes: 30 "<ip_address>"
model9.master_agent.port: <port>

# model9-data
# s3
model9.objstore.endpoint.url: http://minio:9000
model9.objstore.endpoint.userid: <object store access key>
model9.objstore.endpoint.password: <object store secret>

model9.runlogs.expirationScanIntervalMinutes: <min>
model9.runlogs.maxRetentionPeriodDays: <days>

dataSource.user: postgres
dataSource.password: model9
  1. License Key – A valid Model9 license key as obtained in the prerequisites section. When using multiple keys for multiple CPCs, specify one of the keys in the server’s yml file. The server-initiated actions are carried out by the agent using its own defined license. The license key specified for the server is used for displaying a message regarding the upcoming expiration of the license.

  2. Session timeout minutes - Specify the number of minutes following which an inactive UI session will end. The default is 30 minutes.

  3. Master Agent – The agent running on z/OS which verifies the UI login credentials, hostname, IP address and port number.


    Specifying a distributed virtual IP address (Distributed VIPA) can provide high availability by allowing the use of agent groups and multiple agents. See the Administrator and User Guide for more details.

  4. Objstore endpoint – object storage information including:






    Container/bucket name


    default: model9-data


    URL address of local or remote object storage, both HTTP and HTTPS** are supported


    default: none

    Amazon AWS*:

    Google Cloud Storage:


    Access key to object storage


    default: none


    Secret key to object storage


    default: none

    The object storage API name


    default: s3

    Amazon AWS*: aws-s3

    Microsoft Azure: azureblob


    When using object storage that uses V4 signatures, set this parameter to ‘true’ in addition to s3


    default: false Cohesity: true HCP-CS: true


    when using the HTTPS protocol, whether to avoid SSL certificate verifications


    default: true

    * When using Amazon S3, see Appendix C: AWS S3 bucket permissions.

    ** Using HTTPS for the object storage URL parameter enables Data-in-Flight encryption.

  5. Run logs expiration - Setting these parameters will trigger an automatic deletion of run logs from the server. Please note that the deletion is non-recoverable. The automatic deletion will not be executed as long as one of the following parameters is set to (-1):






    This parameter determines the frequency of running the deletion process of old run logs.


    default: -1 (never)


    This parameter determines after how many days a run log will expire and can be deleted by the automatic deletion process.


    default: -1 (never)

  6. DataSource - DB connection information.

Step 6: Starting the Model9 server

Once the object storage is available and the PostgreSQL container is running, start the server:

docker run -d -p -p \
-v $MODEL9_HOME:/model9:z -h $(hostname) --restart unless-stopped \
-e "TZ=America/New_York" \
-e "CATALINA_OPTS=-Xmx2048m -Djdk.nativeCBC=false -Xjit:maxOnsiteCacheSlotForInstanceOf=0" \
--link minio:minio --link model9db:model9db \
--name model9-v2.0.0 model9:v2.0.0.f3aba202
