Oracle数据库_IPDDB_ENABLE参数;
在19.3 alert.log中有如下提示:
ALTER SYSTEM SET _ipddb_enable=TRUE SCOPE=MEMORY SID='xxx';
The setting of the _IPDDB_ENABLE parameter is expected and occurs when Cluster Health Advisor (CHA) is configured, as there is no communication between CHA instances, and so on every startup/shutdown of an instance, the agent will flip the status of the _IPDDB_ENABLE parameter database wide. Therefore you will see as many "alter system" commands setting this parameter in the alert log as there are database instances up.
The parameter is also being changed to a standard parameter in version 23.1.
在Oracle数据库中,_IPDDB_ENABLE参数与集群健康顾问(Cluster Health Advisor, CHA)相关。它主要用于启用与CHA有关的内部功能。CHA是一种监控工具,用于实时监测Oracle集群中各个节点的健康状况并提供诊断信息。以下是_IPDDB_ENABLE参数的一些作用和特点:
总之,_IPDDB_ENABLE在启用CHA过程中扮演了关键角色,帮助数据库管理员更好地监控和管理集群环境的健康状况。如果你正在使用或者计划使用CHA,了解并正确配置这个参数将有助于提高数据库的稳定性和性能。
