Reviseparameterparallelquestion

客户有一套数据库，这周有例行停机维护的时间，于是我们趁这次停机例行维护的时间区间进行PARALLEL_EXECUTION_MESSAGE_SIZE参数的修改，修改完成后在重启的过程中遇到了ORA-00600[KGEADE_IS_0]的错误。首先来说一下为什么要修改PARALLEL_EXECUTION_MESSAGE_SIZE这个参数，根据Oracle最佳实践的推荐，10g默认装完数据库该参数的值是2152，也有可能是2048，推荐将这个值设置成8192，而在11g中，这个值默认被设置成了16K，是可以满足大多数应用场景的。这个值的作用就是在并行执行中消息的大小。这个值越大，需要的shared pool也就越大。虽然能获得更好的性能，但是相应的内存也需要的更多了。还有：这个参数在并行恢复或者是standby recover情况下，增加它的大小到4096以上，也能提升至少20%恢复速度。

我们来看一下我们的报错的情况，我们修改一个节点该参数，然后直接重启。

可以看到，都是在查询GV$视图的语句出现了这个错误。我们在来看一下它出错时候的堆栈信息。

根据文档ORA-600 [kgeade_is_0] In A Real Application Cluster (RAC) Environment (文档 ID 797182.1)里面的描述，凡是trace文件堆栈信息类似于“kxfpg1sg kxfpgsg kxfrAllocSlaves kxfrialo kxfralo qerpx_rowsrc_start”这样的，命中bug8592375。解决这个问题的办法也很简单，就是把两个库实例都停下来，修改成相同的参数，然后启动。像我们这样一个实例还在运行着，使用的是以前的参数，而新实例启动之后用的新的参数，就会导致这个问题的出现。还一个办法是安装补丁程序，但是感觉这个补丁是针对standby数据库的。8592375: PHSB: READABLE STANDBY REPORTED ORA-00700:[KGEADE_IS_0]。

How does MySQL handle data replication?Apr 28, 2025 am 12:25 AM

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

How can you use the EXPLAIN statement to analyze query performance?Apr 28, 2025 am 12:24 AM

The EXPLAIN statement can be used to analyze and improve SQL query performance. 1. Execute the EXPLAIN statement to view the query plan. 2. Analyze the output results, pay attention to access type, index usage and JOIN order. 3. Create or adjust indexes based on the analysis results, optimize JOIN operations, and avoid full table scanning to improve query efficiency.
