Have you ever wondered what the CMNBILOD program that is executed in a number of distributed build procedures actually does? Which input/output DD statements may be specified for use by the CMNBKRST unload/load/forward recovery utility? The JCL parameters that can be supplied to the SERCOPY enhanced copy program? Or anything else related to any of the generic utility programs supplied with the ChangeMan ZMF product?

If so, your first port of call should be the Utilities section of the ChangeMan ZMF Customization Guide. This manual covers all of the information required to allow standard usage of a large number of these utility programs and the 8.3 version can be found here. 

Note also that some more specialised utility programs will be documented in the manual provided for the specific option. For example, module CMNDB2PL is covered in the ChangeMan ZMF Db2 Option Getting Started Guide. So, if you cannot find your required documentation in the Customization Guide, please check the associated option guide, too. Or feel free to open a case with the Support team who will be happy to assist.
