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.
