Overview of the TapeSHARE component
TapeSHARE runs in an BBI-SS PAS and each z/OS image can have only one TapeSHARE running at any time. Therefore, once TapeSHARE is activated in an image, if you attempt to start another TapeSHARE in the same image on another BBI-SS PAS, a warning message is issued and the attempt fails. The BBI-SS PAS continues to initialize.
TapeSHARE includes an operator control display (OCD) that allows you to see the tape sharing activity and have a single point-of-control for tape device management.
You also can track and measure shared tape activity with the BMC AMI OpsA Automation Reporter application which gathers data for items such as how many requests are made for devices and how long it took for TapeSHARE to respond to the request.
