Redacting buffer pool data in SVC dumps for data privacy
Db2 marks buffer pool data in SVC dumps as sensitive=yes for data privacy, and you can redact the data before sending the dump to IBM® Support.
Before you begin
The dump must be captured on a IBM z15® or later processor.
About this task
Enterprises have requirements to prevent customer personal or other sensitive information from being exposed to those who have no need to see the data. In the course of data processing, various types of system and application errors can require you to send diagnostic data to IBM Support or other program vendors, for analysis and problem resolution. Among the types of diagnostic data usually collected for Db2 for z/OS®, buffer pool data in dumps has the greatest exposure to containing sensitive data along with the system and or application data.
Procedure
To redact buffer pool data in SVC dumps for data privacy, complete the following steps:
- Use the sample job SYS1.SAMPLIB(BLSJDPFD) to redact the buffer pool data.
- Retain the original dump until the conclusion of all problem analysis, in case IBM Support requests specific information from the redacted data.
What to do next
To obtain a report about the pages which were marked as sensitive in a redacted dump, use ‘SYS1.SBLSCLI0(BLSXREDR)’ , provide an input dump dataset name, and optionally specify a filtering ASID.
