Bloom Filter bug – Crash

Filed under: Uncategorized — heliodias @ 5:42 pm

ORA-600 [kghfrh:ds] errors leading to a PMON instance crash.

Change the _BLOOM_FILTER_ENABLED to false.

“The Bloom filter, conceived by Burton H. Bloom in 1970, is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set. False positives are possible, but false negatives are not. Elements can be added to the set, but not removed (though this can be addressed with a counting filter). The more elements that are added to the set, the larger the probability of false positives.” Definition of Bloom filter by wikipedia
