结论如下:
no force logging,table nologging, dml nologging,出现ora-26040
no force logging,table logging, dml nologging,未出现ora-26040
force logging, table nologging/logging dml nologging,未出现ora-26040
force logging, table nologging dml logging,未出现ora-26040
force logging, table nologging dml nologging,未出现ora-26040
只有在no force logging、table nologging、dml nologging情况下,recover数据会出现ora-26040,其他情况均正常。
