ORA-55801: Event to control CR activity
Cause: The bit values that we consider. 0x1: Remove fix for bug 3514835 which could potentially throw more 8177 errors We have conservatively blocked some serializability errors, where there could potentially be a dependency between a service transaction in an index and forward going transaction.
Action: Set event 55801 to 1 to disable the bug fix, thereby reducing 8177 error, although it might cause some internal errors instead.
ORA-55801是Oracle数据库中用于控制集市活动的事件错误。
ORA-55801错误指示Cannot Create Event To Control CR Activity错误,表明由于某种原因,无法为Coordinated Replication(CR)活动添加其管理事件(常见事件是发出CONTROL_FILE_RECORD_KEEP_TIME到监督CR记录保存时间的管控活动)。
ORA-55801通常由于在Oracle数据库上某些设置失败而导致,如:
1.缺少SRVCTL环境变量的设置;
2.操作系统环境变量的损坏;
3.orapwd文件丢失/损坏;
4.ORACLE_HOME目录空;
5.无效的ORACLE_HOSTNAME设置;
6.存在安全或管理策略等。
对于ORA-55801错误,建议您根据提示的相关信息,检查在每台节点集群上使用变量srvctl来管理资源,检查srvctlevn设置是否正确,检查用户是否有权限打开数据库和创建各种资源,使用$ORACLE_HOME/bin/srvctl config检查安装完成后,该节点上的命令是否正确,以及orapwd文件是否存在,等等。
