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.
