[PRKS-1009 : Failed to start ASM
stop之后再start还是不行。
分析：
资源状态因为某种原因变为UNKNOWN，，导致无法通过正常方式启动。
解决方法：
客户的系统比较重要，当时先恢复业务，再仔细分析原因。
恢复业务的方法如下：
先强制停止状态为UNKNOWN的资源：
crs_stop -f ora.rac2.ASM2.asm
crs_stop -f ora.rac2.lsnr
再重新启动资源：
crs_start -all
重启之后业务恢复正常。

Apr 09, 2025 am 12:05 AM
Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.
Difference between clustered index and non-clustered index (secondary index) in InnoDB.
Apr 02, 2025 pm 06:25 PM
The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
