Category 3 transactions

Category 3 transactions are either initiated by the terminal user or associated with a terminal. All CICS® terminal users, whether they are signed on or not, require access to transactions in this category. For this reason, category 3 transactions are exempt from any security check, and CICS permits any terminal user to initiate these transactions.

For category 3 transactions you are recommended to specify RESSEC(NO) and CMDSEC(NO) on the CICS transaction resource definition. These transactions should be defined to RACF; although this definition does not affect task attach-time processing, it is required to support the QUERY SECURITY command.

Table 1 lists the category 3 transactions.
