Environment variables that affect CPACF usage
The CSU_HCPUACLR and CSU_HCPUAPRT environment variables control whether the CPACF is used for certain CCA functions.
These variables are overridden by the explicit use of the Cryptographic Resource Allocate (CSUACRA)
and Cryptographic Resource Deallocate (CSUACRD)
verbs to enable or disable these access patterns. To avoid confusion,
the environment variables are given similar names to the keywords
used by Cryptographic Resource Allocate (CSUACRA)
and Cryptographic Resource Deallocate (CSUACRD).
Note: The
default values listed here are valid even if these environment variables
are not defined. Their settings represent default policy decisions
made in the library code.
