Action: The error is signalled after retrying migration for 500 times. Run migration when there is less of segment creation activity is Going on.
1、查看日志,查看当前执行迁移操作时操作都是正确的,一切正常执行正确,可能是一个正常步骤执行太慢,造成整个操作超时,出现ORA-03248问题。
2、检查当前数据库状态是否正常,如果存在性能问题,及时解决,确保迁移过程中主机上的数据库可以正常工作。
3、分析当前的数据库迁移模式,找出执行时耗时最长的步骤,如果执行步骤耗时较久,可以考虑将导致耗时过长的查询语句优化;或者将一次迁移的数据量减少,一次性迁移较大的数据量易引发该类错误。
4、如果ORA-03248错误因误操作造成,可以考虑将数据库迁移操作从头重新执行一遍,更加细致地进行操作,而不是急于地将数据迁移完成,以免出现重复操作上出现错误而产生类似ORA-03248的错误提示。
