If you are installing a z/OS CBPDO order...

If you ordered z/OS® as a CBPDO package:

Install all PTFs with a SOURCEID of ZOSV2R1. In addition, install all PTFs with a SOURCEID of HIPER or PRP provided they are not in a PTF-in-error (PE) chain.
Consult Memo to Users Extension to find the service level of the system as shipped.
If more than a few weeks have passed since your order arrived, there should be a service package available; order and apply it in accordance with the guidelines in Maintenance after installation. Use the service delivery vehicle that you prefer, such as ShopzSeries or SMP/E Internet Service Retrieval.
