VCPG-67-000016 - VMware Postgres must write log entries to disk prior to returning operation success or failure - full_page_writes

Information

Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. Preserving system state information helps to facilitate system restart and return to the operational mode of the organization with less disruption of mission/business processes.

Aggregating log writes saves on performance but leaves a window for log data loss. The logging system inside VMware Postgres is capable of writing logs to disk fully and completely before the associated operation is returned to the client. This ensures that database activity is always captured, even in the event of a system crash during or immediately after a given operation.

Solution

At the command prompt, execute the following commands:

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c 'ALTER SYSTEM SET <name> TO 'on';'

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c 'SELECT pg_reload_conf();'

Note: Substitute <name> with the incorrectly set parameter (fsync, full_page_writes, synchronous_commit)
