Troubleshooting Oracle 12cR2 Standby database crash due to Corrrupted block
最近一套oracle 12c R2的数据库日志应用总是中断,并且在standby 节点发现了一些坏块,存储检查正常,并且primary db端并没有发现坏块,standby db alert log中发现了大量的ora-600报错,当前可能为logical corruption(Internal inconsistency in the block while the block may have good header and footer. The block checksum will be correct but the block structures may be corrupt.),ADG的ABMR并没有自动修复该错误。这里简单记录。
