Your installation has allocated two data sets for the primary RACF® database:
- SYS1.RACFP1—1st primary data set
- SYS1.RACFP2—2nd primary data set
For recovery, the installation also wants a backup data set for
each primary RACF data set,
although the backup of the data sets is different:
- For SYS1.RACFP1, all updates to the primary data set, except statistics,
are duplicated on the backup data set.
- For SYS1.RACFP2, all updates to the primary data set, including
statistics, are duplicated on the backup data set.
Note: - The sysplex communication bit is specified only in the entry for
the first data set. The data sharing bit is off.
- RACF allocates 51 (255
× .20) resident data blocks for the first backup data set buffer and
10 (50 × .20) for the second.
The following data set name table correctly follows these criteria:
Figure 1. ICHRDSNT example
3 — sysplex communication and split database- AL1(2)
- Number of data sets in the primary RACF database
- CL44'SYS1.RACFP1'
- Name of first data set in the primary RACF database
- CL44'SYS1.RACFB1'
- Name of first data set in the backup RACF database
- AL1(255)
- Number of resident data blocks (for primary data set)
- X'88'
- Flags; all updates other than statistics are to be duplicated
on the backup data set. The sysplex communication bit is on, and the
data sharing bit is off.
- CL44'SYS1.RACFP2'
- Name of second data set in the primary RACF database
- CL44'SYS1.RACFB2'
- Name of second data set in the backup RACF database
- AL1(50)
- Number of resident data blocks
- X'C0'
- Flags; all updates, including statistics, are to be duplicated
in the backup data set.
