这是一个Oracle数据库错误。由于发生了一种情况,导致不能启动并行预处理工作,从而出现了这个错误。
ORA-15517 occurs when an attempt is made to start a parallel preprocessor worker which has already been started.
常见的情况是,当用户尝试将一个已经启动的并行预处理工作重新启动时,将会出现ORA-15517错误。
1. 使用以下SQL查询查找正在运行的并行预处理工作的ID:
SELECT * FROM v$px_process;
2. 用相应的ID停止此工作:
ALTER SYSTEM STOP PARALLEL PREPROCESSOR WORKER ;
注意: 请确保只有一个并行预处理工作正在运行,以避免出现ORA-15517错误。
