A sensitive memory area is an allocated memory area that contains sensitive data. The direct I/O buffer attribute SENSITIVE is a programmatic method that identifies a memory area containing sensitive information.
When you specify a memory area using the SENSITIVE attribute, it indicates to diagnostic processes (for example, memory and program dumps) that data for these memory areas should be excluded. The MCP automatically excludes sensitive data for
-
ALLINUSE memory dumps
-
PARTIAL memory dumps
-
MINIMAL memory dumps
-
Program dumps to disk files
Only the following types of dumps could potentially contain sensitive information:
-
COMPLETE memory dumps that are generated by the MCP
-
MCP environment dumps that are generated by the console
The DUMPANALYER HEADING command reports the status of dump files that contain sensitive information. The following table describes the messages that are generated by the HEADING command when a dump contains sensitive information.

Message |
Explanation |
|---|---|
|
WARNING: This dump contains sensitive data. Use the SCRUB command to remove the sensitive data from this dump. |
This warning indicates that the dump file includes information of one or more sensitive memory areas. Use the SCRUB command to remove information from these areas. |
|
Sensitive data was scrubbed from this dump by the MCP |
This message indicates that the MCP scrubbed the contents of sensitive memory areas as part of the dumping process. This message applies to program dumps and ALLINUSE, PARTIAL, and MINIMAL memory dumps. |
|
Sensitive data was scrubbed from this dump by DUMPANALYZER. |
This message indicates that information from one or more sensitive memory areas has been removed from the dump using DUMPANALYZER SCRUB command. |
You can use the SCRUB command to remove sensitive information from a dump. The SCRUB command creates a new dump file that excludes information from all sensitive memory areas. For more information on the SCRUB command, see SCRUB (Scrub Sensitive Memory Areas).
