揭秘 Oracle 11gR2 RAC ASM Instance 启动

2023-06-122012-07-20 by weejar zhang

存储asm instance spfile到asm，听上去很奇怪，启动自身，首先要解决的几个问题
1,asm diskgroup 没mount,如何读spfile?
2,在oracle_home/dbs下没有参数文件，如何知道spfile在哪?
3,不知道spfile，怎么知道的asm_diskstring?

oracle 11g BaseLine(基线)指定application中不可修改sql的执行计划

2025-07-152012-07-11 by weejar zhang

11G前有sql profile、outline可以稳定执行计划，但有些文档中指出有时outline指定了但也有要能走新的执行计划，所以11g的BASELINE是OUTLINE的改进版。一般应用在版本升级或稳定特定SQL的执行计划，也可以修改指定SQL的执行计划，当OUTLINE与BASELINE有同时指定时BASELINE有优先权。
