Updates to OPJ2CB are on a z/OS release boundary. So, when z/OS 2.3 becomes GA, we will publish a new PTF for all supported OPS/MVS releases. This is not considered a Hyper PTF and therefore customers will not get automatic notifications of it. (Customers must sign up to receive Hyper Notification on CA Support Online). When a customer upgrades to a new version of z/OS, they should review the available FIXCAT HOLDDATA link on the z/OS Compatibility Matrix page. Here they will be able to download the available fixes for the particular hardware device, software or function. In this case, any JES2 updates will be in the z/OS updates. This applies to all z/OS based products.
