Network load

zSecure Admin and Audit do not generate any significant network load. However, both applications also provide the option to do remote reporting and analysis using the zSecure server (program CKNSERVE). If you use the zSecure server to access remote data, the network load is dependent on the data needed for the report. Each call of CKRCARLA results in the transfer of all data required for the selected reports. For typical audit reports, this often involves the entire CKFREEZE data set and the entire RACF® database. If you do not specify a CKFREEZE data set, a mini-CKFREEZE is used. The size of a mini-CKFREEZE is about 1 MB. This data set is always transferred in full.

For RACF reports, the zSecure Server transfers only the number of profiles needed for the report, or transfers the entire security database. This is dependent on the selection criteria used in the query and the information that is to be included in the report. For ACF2 and SMF reports, all data is transferred, and selection is done in the client application.

The zSecure Server uses point to point connections using TCPIP. It uses a single listening port that can be specified during configuration, and one ephemeral port for each configured partner server. The server must be active on all systems from which you want to retrieve information, or to which you want to send commands.
