Notes:
1. The “xxxINSTL” field points to the installation parameter list only if you specify
INSTLN on the ESMEXITS system initialization parameter. The default value of
this parameter is NOINSTLN, which means that no installation data is passed.
2. RLX2PRPA contains the address of the ICHRLX01 user exit parameter list
(RLX1P). Field RLX1INST of RLX1P in turn points to the installation data
parameter list.
For full descriptions of the RACF exit parameter lists, see the OS/390 Security
Server (RACF) Security Administrator’s Guide manual. For more information about
CICS security processing using RACF, see the
CICS RACF Security Guide.
The installation data parameter list
The installation data parameter list gives your ESM exit programs access to the
following information:
v The CICS security event being processed.
v Details of the current CICS environment. That is:
– The applid of the CICS region
– The common work area (CWA)
– The transaction being invoked
– The program being executed
– The CICS terminal identifier
– The VTAM LU name
– The terminal user area.
You can map the installation parameter list using the macro DFHXSUXP. The
DSECT DFHXSUXP contains the following fields:
UXPLEN
A halfword containing the length of this parameter list in bytes.
UXPARROW
Arrow “eyecatcher” (>).
UXPDFHXS
The name of the owning component (DFHXS).
