ICSF Initialization (Subtype 1)

When ICSF starts, ICSF writes to subtype 1 after initialization is completed. Subtype 1 describes the values of installation options that are specified in the installation options data set.

Subtype 1 contains this information:

Special secure mode (SSM) option
Security Server (RACF) checking of Supervisor State and System Key callers (CHECKAUTH) option
Compatibility mode with CUSP or PCF (COMPAT) option
Cryptographic domain number (DOMAIN) option
CKDS name (CKDSN) option
Maximum length for data in a callable service (MAXLEN) option
Beginning with z/OS V1 R2, the MAXLEN parameter may still be specified in the options data set, but only the maximum value limit will be enforced (2147483647). If a value greater than this is specified, an error will result and ICSF will not start.
User parameter (USERPARM) option
PKDS name (PKDSN) option
TKDS name (TKDSN) option

SMF records for this subtype will also contain a server user audit section.
