ACEE compression/expansion exits z/OS Security Server RACF System Programmer's Guide SA23-2287-00 |

When RACF® compresses an
ACEE, it stores the ACEE as one contiguous area, called an ENVR object,
containing no pointers. ACEEIEP
can point to various user-defined data structures which can be non-contiguous.
Because the data that needs to be saved is pointed to in nonstandard
ways, RACF provides two exits
that allow an installation to tell RACF what
data to save, in addition to the ACEE itself. The two exits are:
These exits are called as part of compressing or expanding an ACEE, which can occur during the processing of some commands and RACROUTE requests (see Table 1 for details) and during the processing of the initACEE callable service. It is expected that most installations will not have to code the ACEE compression/expansion exits. Installations that do not use ACEEIEP, and installations that have ACEEIEP pointing to standard data in RACF's standard format, do not need to provide these exits. However, if an installation is making a nonstandard use of ACEEIEP, in task mode and non-cross-memory environments it can use the ACEE compression/expansion exits to ensure that the compressed or expanded ACEE contains the installation's data. Note, however, that the exits do not get control for ACEE expansion in SRB mode or cross memory mode. In these cases, the installation should have ACEEIEP point only to standard data. Standard data for ACEEIEP: Standard data for ACEEIEP has the following characteristics:
Nonstandard use of ACEEIEP: Examples of nonstandard use
of ACEEIEP are:
Note: If you currently use ACEEIEP in a nonstandard format and do
not provide IRRACX01 and IRRACX02 exits, you might experience unpredictable
results after the IRRACEE VLF class is activated. You might also experience
unpredictable results if you have applications that use the ENVRIN,
ENVROUT, and NESTED=YES keywords on RACROUTE macros. Be sure to check
whether applications you use do this.
