Activate the Transparency
Learn how to activate the transparency.
The procedures for installing and activating
Datacom VSAM Transparency
are documented in Installing. To activate the Transparency for the first time, install Datacom VSAM Transparency
and initialize the subsystem (which handles batch processing). The subsystem is initialized in one of the installation steps through the use of CAIRIM, and is active throughout the life of the current IPL. Subsequently, you can either activate the subsystem automatically each time you IPL your operating system or you can rerun the CAIRIM installation step to activate the subsystem after an IPL.
When activated, z/OS links to DVVSIPR, the initialization module for the
Datacom VSAM Transparency
Subsystem, which loads DVVSSPR and builds the subsystem communication vector table. This table provides the means of invoking subsystem modules to handle opens, closes, JCL conversion, and allocation conditions.
