The IBM® z/OS® CICS® collection, also represented as ibm_zos_cics in this document, is part of the broader initiative to bring Ansible Automation to IBM Z® through the offering Red Hat® Ansible Certified Content for IBM Z®. The IBM z/OS CICS collection supports management of CICS resources and definitions through the CMCI REST API provided by CICS as well as provisioning of standalone CICS regions.
This CICS collection works in conjunction with other Ansible collections for IBM Z, such as the IBM z/OS core collection. It is also possible to use it independently to perform automation tasks solely in CICS.
Red Hat® Ansible Certified Content for IBM Z provides the ability to connect IBM Z® to clients' wider enterprise automation strategy through the Ansible Automation Platform ecosystem. This enables development and operations automation on Z through a seamless, unified workflow orchestration with configuration management, provisioning, and application deployment in one easy-to-use platform.
The IBM z/OS CICS collection is following the Red Hat® Ansible Certified Content for IBM Z® method of distributing content. Collections will be developed in the open, and when content is ready for use it is released to Ansible Galaxy for community adoption. Once contributors review community usage, feedback, and are satisfied with the content published, the collection will then be released to Ansible Automation Hub as certified and IBM supported for Red Hat® Ansible Automation Platform subscribers.
For guides and reference, please review the documentation.
The IBM CICS collection includes modules, sample playbooks, and ansible-doc to:
- Automate tasks in CICS.
- Provision or deprovision CICS regions.
- Start or stop a CICS region.
The tasks in the IBM® z/OS® CICS® collection can be classified into two types, CMCI tasks and provisioning tasks, and they have different requirements for the managed nodes.
For details on the different requirements, please see here.
You can install this collection with the Ansible Galaxy command-line tool:
ansible-galaxy collection install ibm.ibm_zos_cicsYou can also include it in a requirements.yml file and install it with ansible-galaxy collection install -r requirements.yml, using the format:
collections:
- name: ibm.ibm_zos_cicsTo install a specific version of the collection or upgrade an an existing installation to a specific version, for example installing 2.1.0, use the following syntax:
ansible-galaxy collection install ibm.ibm_zos_cics:2.1.0If you want to upgrade the collection to the latest version, you can run:
ansible-galaxy collection install ibm.ibm_zos_cics --upgradeAs part of the installation, the collection requirements must be made available to Ansible through the use of environment variables. The preferred configuration is to place the environment variables in group_vars and host_vars. An example of the variables file can be seen here:
pyz: "path_to_python_installation_on_zos_target"
zoau: "path_to_zoau_installation_on_zos_target"
environment_vars:
_BPXK_AUTOCVT: "ON"
ZOAU_HOME: "{{ zoau }}"
PYTHONPATH: "{{ zoau }}/lib"
LIBPATH: "{{ zoau }}/lib:{{ pyz }}/lib:/lib:/usr/lib:."
PATH: "{{ zoau }}/bin:{{ pyz }}/bin:/bin:/var/bin"
_CEE_RUNOPTS: "FILETAG(AUTOCVT,AUTOTAG) POSIX(ON)"
_TAG_REDIR_ERR: "txt"
_TAG_REDIR_IN: "txt"
_TAG_REDIR_OUT: "txt"
LANG: "C"- Use Case Name: Provision a standalone CICS region
- Actors:
- System Programmer
- Description:
- A system programmer can provision a set of region data sets and start up a standalone CICS region.
- Flow:
- Create and activate a VTAM node to ensure user had a valid applid
- Create region data sets
- Update the CSD data set with a CSDUP script
- Create CICS startup JCL data set
- Submit the CICS startup JCL data set as a job using zoau's jsub.
- Actors:
- Use Case Name: Deprovision a standalone CICS region
- Actors:
- System Programmer
- Description:
- A system programmer can stop a standalone cics region and delete the region data sets.
- Flow:
- Stop the CICS region
- Check the CICS region has been shut down
- If it has not stopped, shut the region down with state "immediate" or cancel the job.
- Delete the region data sets
- Delete the CICS startup JCL data set
- Actors:
- Use Case Name: Provision an SMSS CICS region
- Actors:
- System Programmer
- Description:
- A system programmer can start a SMSS CICS region.
- Flow:
- Create and activate a VTAM node to ensure user had a valid applid
- Ensure user has an allocated/free port available
- Create region data sets
- Update the CSD data with a CSDUP script which also alters the TCPIP service
- Create CICS startup JCL data set
- Submit the CICS startup JCL data set as a job using zoau's jsub task
- Actors:
- Use Case Name: Install a bundle in a CICS region
- Actors:
- Application Developer
- Description:
- An application developer can install a CICS bundle into a CICS region
- Flow:
- Find if the CICS bundle already exists in target region
- Disable and discard existing CICS bundle
- Install bundle definition into target region
- Wait for bundle to reach enabled status
- Use Case Name: Deploy a program to a CICS region
- Actors:
- Application Developer
- Description:
- An application developer can deploy a program to a CICS region
- Flow:
- Copy load module to load library
- Use NEWCOPY PROGRAM to deploy program into CICS
