It is not always obvious to customers exactly where the initial attributes assigned to ERO Release Area datasets are defined. This information may be accessed in the following manner:

• Select ISPF Option A (Admin) – R (ERO) – A (Application).
• List the release.
• Use line command RA to display applications joined to this release.
• Enter line command AL to list the library types.
• Enter line command QL to display the default allocation settings or UL to update them.

Note: The library type allocation characteristics will only apply BEFORE the area dataset is created. Although updates to the definition panel may be allowed after this point, the dataset will already have been allocated and users will often see the following type of message issued in this situation:

Not All Changes Allowed/CMR5502A - Library Type(s) JCL area libraries already allocated.

Further information on allocating release area library types may be found in the section entitled ‘Define Application Library Types’ in the ChangeMan ZMF ERO Getting Started Guide, the 8.3 version of which may be found here.
