GLYPH<SM590000> What user IDs will access them? GLYPH<SM590000> What access is required by these user IDs? When you run the zCX workflow in z/OSMF, a directory of the name of the zCX instance that  you are creating is created in a USS directory that you specify. A number of files are also  written to this directory when the workflow runs. This implies that the user ID that runs the z/OSMF workflow needs to have update access to  the USS directory that you specify for creation of the instance directory. If you have a sysplex, you also must consider whether you want the flexibility to start the zCX  instances on any LPAR in the sysplex. If you do want this flexibility, specify a USS directory  that is visible to all LPARs in the sysplex. From z/OS 2.3 on, there is a directory called  global  that is defined under the root directory.  Thus, by default your z/OS sysplex has a directory that is common to all LPARs in that  sysplex. We used  global  as the parent directory to store files that are related to the  configuration of our zCX instances. That way, we could start the zCX instances on any LPAR  in our sysplex as needed. In our environment, we created a directory called  zcx  under the  global  directory. Then, we  defined a zFS and mounted it at the  /global/zcx  directory prior to the creation of the  lower-level directories. Table 4-3 shows the directories that we then created in our environment and their purpose. Table 4-3 zCX configuration directories Directory Purpose /global/zcx/cfg Parent directory for various files related to configuring zCX instances /global/zcx/cfg/properties Directory to store customized property files for use in zCX workflows /global/zcx/instances Parent directory for each created zCX instance directory 54  Getting started with z/OS Container Extensions
