 |APF Authorize privileged content | <br />**Purpose:**<br /> The majority of Zowe is unprivileged code running in Key 8. Zowe relies on a single component called ZIS to own all of the privileged code logic. The load library for the ZIS component and its extension library must be set as APF authorized and run in Key 4 to use ZIS and components that depend upon it. <br /> **Action:**<br />1) APF authorize the datasets defined at `zowe.setup.dataset.authLoadlib` and `zowe.setup.dataset.authPluginLib`. <br />2) Define PPT entries for the members `ZWESIS01` and `ZWESAUX` as Key 4, NOSWAP in the `SCHEDxx` member of the system PARMLIB. | [ZWEIAPF](https://github.com/zowe/zowe-install-packaging/tree/feature/v3/jcl/files/SZWESAMP/ZWEIAPF) <br />
