ORA-32511: cannot create watchpoint in memory needed by watchpointing code

文档解释

ORA-32511: cannot create watchpoint in memory needed by watchpointing code

Cause: overlap exists between requested memory range to watch and internal memory structures that watchpointing operations need

Action: provide a different address range

ORA-32511错误，是由于Oracle中监控点的内存不足导致的。

官方解释

ORA-32511: cannot create watchpoint in memory needed by watchpointing code

Cause: Memory needed by watchpointing code was not available.

Action: Make sure that memory needed by watchpoint in memory is available.

常见案例

ORA-32511错误一般是由于内存不足导致的。在使用监控功能时，Oracle会扫描数据库中的系统表，来检查表空间、数据文件大小、数据量等，如果使用的内存过少，会导致此错误。

一般处理方法及步骤

1.检查系统内存是否足够，如果不够，可以考虑增加内存。

2.检查硬盘空间是否充足，出现ORA-32511错误时，可能是硬盘空间不足导致。

3.将ORACLE_HOME rc amesWPD（watchpoint definition）文件夹中的文件删除，该文件夹存放着监控点相关的内存，内存占用可能较高，删除这些文件可以释放空间。

4.重新启动Oracle实例，重新加载监控配置，释放内存，以减少对内存的占用。
