This document describes how to troubleshoot issues where there are significant waits for 'latch: cache buffers chains'. Latch: cache buffer chains (%)
The cache buffers chains latches are used to protect a buffer list in the buffer cache. These latches are used when searching for, adding, or removing a buffer A user process acquires the CACHE BUFFERS CHAINS latch to scan the System Global Area (SGA) for database cache buffers. latch: cache buffers chains latch contention – a better way for finding

Deep Dive sessions from Oracle Guru "Arup" on DB Security , Indexes and Buffer cache in Cloud The cache buffers chains latch is actually made up of a large number of child latches. When Oracle needs to access the buffer cache it hashes
Tuning Latch Contention: Cache-buffers-chain latches cache buffer chains (cbc) latches are the latches used to protect the buffer cache. There are lists of blocks, each list is protected by one of these latches. A The Oracle buffer cache is amazing and key to Oracle performance. In this webinar, TOGETHER we will explore one of your

Oracle Cache Buffers Chain Latch The latch: cache buffers chains event occurs when multiple processes try to access the same data blocks in the buffer cache, leading to contention for latches.
