About This Book This book contains information about the Resource Access Control Facility (RACF), which is part of the OS/390 Security Server. The Security Server has two components: RACF OpenEdition DCE Security Server For information about the OpenEdition DCE Security Server, see the publications related to that component.
Chapter 6, “Customization Considerations” on page 29, highlights information about customizing function to take advantage of new support after the new release of RACF is installed. Chapter 7, “Administration Considerations” on page 31, summarizes changes to administration procedures for the new release of RACF.
RACF Courses The following RACF classroom courses are also available: Effective RACF Administration, H3927 MVS/ESA RACF Security Topics, H3918 Implementing RACF Security for CICS/ESA, H3992 IBM provides a variety of educational offerings for RACF.
Other Sources of Information IBM provides customer-accessible discussion areas where RACF may be discussed by customer and IBM participants. Other information is available through the Internet. IBM Discussion Areas Two discussion areas provided by IBM are the MVSRACF discussion and the SECURITY discussion.
You can get sample code, internally-developed tools, and exits to help you use RACF. All this code works in our environment, at the time we make it available, but is not officially supported. Each tool or sample has a README file that describes the tool or sample and any restrictions on its use.

Chapter 1. Planning for Migration This chapter provides information to help you plan your installation's migration to the new release of OS/390 Security Server (RACF). Before attempting to migrate, you should define a plan to ensure a smooth and orderly transition.
Installation Considerations Before installing a new release of RACF, you must determine what updates are needed for IBM-supplied products, system libraries, and non-IBM products. (Procedures for installing RACF are described in the program directory shipped with OS/390, not in this book.
Auditing Considerations Auditors who are responsible for ensuring proper access control and accountability for their installation are interested in changes to security options, audit records, and report generation utilities. For more information, see Chapter 8, “Auditing Considerations” on page 33.

Chapter 2. Release Overview This chapter lists the new and enhanced functions of RACF for OS/390 Release 4 and gives a brief overview of each new function or function enhancement.
Enhancements to Support for OpenEdition Services Enhancements to RACF's support for OpenEdition services include: Extended ability to audit the use of superuser status Default USER/GROUP .
The getUMAP and getGMAP services also look for default values. If getUMAP is given a UID as input and the corresponding USER profile has no OMVS segment, the caller of the getUMAP service receives the default. If no default value is found, RACF return code 8, reason code 4 are returned by the getUMAP service.
The ALTUSER command allows an administrator to reset a user's password to a temporary password or a default value. This command is modified to save the old password whenever the password is reset. The PASSWORD USER ( userid ) command provides users and administrators with a password reset function.
system. This support provides a solution to many customers that find themselves in such a situation. The PERMIT command has a new keyword to add users and groups to the conditional access list, WHEN(SYSID(...)). This keyword is allowed only for the PROGRAM class.
Enable/Disable Changes OS/390 Version 2 Release 4 has a new product ID that affects the enable/disable function in all of its elements including the Security Server. The ID() value used in the IFAPRDxx parmlib member needs to be "5647-A01". The remainder of the parameters remain the same.
Chapter 3. Summary of Changes to RACF Components for OS/390 Release 4 This chapter summarizes the new and changed components of OS/390 Release 4 Security Server (RACF).
Figure 2. Changed Callable Services Callable Service Name Description Support initUSP If no OMVS segment is found in the user's profile, the initUSP service checks the BPX.DEFAULT.USER profile in the FACILITY class. This profile may contain a user ID in its application data field that provides a default OMVS segment.
Figure 3. New Classes Name Description Support DSNADM DB2 administrative authority class DB2 GDSNBP Grouping class for buffer pool privileges DB2 GDSNCL Grouping class for collection privileges DB2 GD.
Figure 4 (Page 2 of 3). Changes to RACF Commands Command Description Support ALTUSER This command supports the removal of all of the user's CLAUTH authorities by using NOCLAUTH(*). For more information on the ALTUSER NOCLAUTH keywords, see OS/390 Security Server (RACF) Command Language Reference .
Figure 4 (Page 3 of 3). Changes to RACF Commands Command Description Support TARGET The new keyword WDSQUAL is added to the RACF TARGET command to indicate that the variable that follows will be used .
Figure 5. Changes to PSPI Data Areas Data Area Description Support AFC This data area maps the contents for the Open Edition MVS security audit function codes. An audit function code has been added to audit when ck_priv is called from OpenEdition_spawn (BPX1SPN).
RFXALET and RFXLOGS correspond to new fields in the RACROUTE REQUEST=FASTAUTH parameter list. These fields only exist in parameter lists created with RELEASE=2.4 or higher. Therefore, these fields must only be accessed when the RFXPVERS indicates Release 2.
