Data privacy precautions can be implemented for the generation and storage of a dump. By marking memory pages as “secret pages”, you can prevent them from being transferred from the system dump, user dump or area dump to the dump files.
In order to do this, the system parameter DUMPSEPA must have been set accordingly at system initialization by using the parameter service (see the manual “Introduction to System Administration” [6]). Pages can be marked as SECRET PAGES via the CSTAT macro (see the “Executive Macros” manual [4]) or $CSTA. This is specially advisable when dealing with sensitive data. You should check whether this data may be of relevance for diagnostic purposes.
Dumps which contain confidential data are stored under special user IDs (SYSUSER, SYSDUMP, SYSSNAP, TSOS); the access rights for these user IDs are assigned by systems support.
