4.7 zCX property file 4.7.1 Customizing the properties file When you execute the zCX provisioning workflow in z/OSMF, you must supply several  parameters. You can manually enter values for these parameters in the workflow panels. However, it is recommended that you make a copy of the supplied sample zCX properties file,  and set your custom values in that file. That way, you can reuse that property file as input to  other supplied provisioning workflows for your instance, such as deprovision or  reconfiguration. When you start any of these zCX provisioning workflows, you can supply  your customized property file as an input file, and avoid manually typing in the values again. The sample zCX properties file is typically supplied on your z/OS LPAR in this path: /usr/lpp/zcx_zos/properties/workflow_variables.properties We copied the supplied zCX property file to the location that is shown in Example 4-11 and  gave it a name that reflects the name of the zCX instance that we planned to create: Example 4-11 Property file /global/zcx/cfg/properties/zcxed01_workflow_vars.properties Notice that the file is stored in EBCDIC in the z/OS USS environment. We then edited that file, making the changes shown in Table 4-5.
