Operating software requirements

IMS 15.5 and its various functions have specific operating software requirements.

Before you install IMS 15.5, check for any preventive service planning (PSP) information that you need to be aware of. IMS 15.5 does not provide PSP buckets, instead, refer to PSP bucket information for IBM Z products for equivalent information.

The z/OS® service levels that are required for installation and execution are described in the Program Directory for Information Management System Transaction and Database Servers V15.05.00.
