Support gracefull data recovery in even when datafile are corrupted.
---------------------------------------------------------------------
Key: AMQ-2405
URL: https://issues.apache.org/activemq/browse/AMQ-2405
Project: ActiveMQ
Issue Type: New Feature
Reporter: Hiram Chirino
Related to AMQ-2337
I will shortly be submitting a patch to which updates the kahadb store so that:
* setting checksumJournalFiles="true" - enables journal file check-summing
* setting checkForCorruptJournalFiles="true" - enables start up validation of
all the journal data files against the checksums
If checkForCorruptJournalFiles is enabled, any journal files which did not have
checksum data record will be skipped during checksum validation. Enabling
checksumJournalFiles only affects new journal records created and does not
update existing journal records.
If a journal checksum violation is detected the broker will fail to to start up
and report the error.
If you want to ignore the corrupted areas of the datafile (instead of failing
to start the broker), you should enable the ignoreMissingJournalfiles="true"
option.
