Latch Cache Buffers Chains at Julius Scudder blog

Latch Cache Buffers Chains. in this blog you learned how oracle manages the buffer cache and how latches are used to ensure only one process can walk the chain to access. Cache buffers chains can be resolved by one of the following. Fix the execution plan of the query (by getting. Here is a schematic of computer memory and the oracle processes, sga and the main components of the sga: 2) if the plan is poor, then from the sql, a. When a buffer is requested the hash value of the chain where the buffer is, will be calculated and then that chain is scanned by walking the chain until the buffer is found. The buffer cache hold in memory versions of datablocks for faster access. the buffer cache is implemented as a chain of blocks linked together under a hash value known as cache buffer chains (cbc). the cbc latch protects information controlling the buffer cache. here's a treat for oracle performance professionals and geeks who are looking for more systematic ways for. 1) if the buffer count is low, you can spread out the table blocks by either. this document describes how to troubleshoot issues where there are significant waits for 'latch:
