It is not always possible for Z Abend Investigator to provide CICS 3270 screen buffer information. For example, if there are indications of VTAM® session errors on the terminal, or if one of the following CICS abends have occurred (* indicates a wildcard character), then no 3270 screen buffer information is provided:
Two point-and-shoot fields are provided under the panel title to toggle the state of the display: The selected option is remembered between interactive analysis sessions.
When the CICS 3270 screen buffer is available, it is displayed to all users by default. You can restrict its display to users who have READ access or higher to an XFACILIT profile named HFZ_FEATURE_DISPLAY_CICS_3270BUFFER. For example, the following RACF commands restrict the 3270 screen buffer display to members of group DEV1:

RDEFINE XFACILIT HFZ_FEATURE_DISPLAY_CICS_3270BUFFER UACC(NONE)
PERMIT HFZ_FEATURE_DISPLAY_CICS_3270BUFFER CLASS(XFACILIT) ID(DEV1) ACCESS(READ)
Note: The contents of the CICS 3270 screen buffer are visible if a user views a fault entry outside of Z Abend Investigator (for example, using ISPF BROWSE). To control this level of access, define the history file data-set-profile access as UACC(NONE), and define an XFACILIT profile that grants access to the history files. See Using the XFACILIT resource class for history file fault entries.
