Managing Special Files
CPU-Independent Files
It may be necessary to differentiate between systems, as well as between
partitions, in a multi-CPU environment (multiple real or multiple virtual
systems). Generate this support by doing both of the following:
• Specifying the MULTCPU(YES) in the DYNAM/T option record
• Updating the system adapter option record. This option record, the same
used for multi-CPU support for CA Dynam/D, produces a table of CPU
serial numbers, each associated with a unique identification character.
These characters are used to provide CPU-independent data set names in
conjunction with partition-independent data set names.
Examples:
// TLBL dtfname,'==@WORK' (partition- and CPU-independent)
// TLBL dtfname,'@WORK' (CPU-independent)
The special character @ will be replaced with the CPU ID established for the
machine. The CPU ID character can appear in either of the following ways:
• Following or preceding the partition ID characters as in the first example
• Alone as the ID in the second example
If the TLBLs above were processed in the BG partition in machine A, the
resulting data set names would be BGAWORK and AWORK, respectively.
The following CPU-independent substitutions are supported by CA Dynam/T:
Substitution Example Resolved Data Set Name
@ @WORK AWORK
== ==FILE BGFILE
@== @==WORK ABGWORK
==@ ==@FILE BGAFILE
=== ===WORK BGAWORK
If the CPUID definition phase has not been cataloged, a default value of A is
used whenever the CPUID is required by the system.
For more information about instructions on updating the CPUID System
Adapter option record and an illustration of how to use it, see the CA CIS
Administrator Guide.
