ORA-16744 : the DG_CONFIG list of LOG_ARCHIVE_CONFIG parameter is full
这是一个系统参数错误,它发生在当应用程序试图把一个值追加到多余的位置的数组的情况下。
1.检查参数 DG_CONFIG 的内容:select name,value from v$parameter where name=’dg_config’;
2.使用 ALTER SYSTEM 命令移除不再需要的值:ALTER SYSTEM SET DG_CONFIG = “dg1=lat1,lat2,lat3”;
3.再次检查 DG_CONFIG 参数的内容:SELECT name,value FROM v$parameter WHERE name=’dg_config’;
4.如果问题仍然存在,请重启实例 DB。
