Oracle Kernel : Function kglic & Library Cache Latch
时间：2022-06-29 10:05:31 编辑：袖梨 来源：一聚教程网
以下是关于KGLIC函数的功能简要说明：
| 代码如下 | 复制代码 |
|
1. kglic means Kernel Generic Library cache Iterate Chain (AFAIK), it's the function which is executed when you access most X$KGL tables. 2. kglic is the code which goes through the library cache and row cache to answer queries on various dictionary fixed views and tables. This is the function which returns data for the fixed views and tables that scan the sql area. Therefore, it was highly possible that such queries could also be coming from monitoring tools used by DBAs and they are not restricted to the two views specifically mentioned in the bug by Joan. Any monitoring job which looks at v$open_cursor would also use the kglic iterator. |

与此相关的BUG，在10g中仍然存在，最后确认客户有较为频繁的查询访问v$sql视图，导致了严重的library cache的竞争。
以下BUG的影响版本为10.2.0.4，10.2.0.5，11.2.0.2 ：
