新的Oracle数据库

Question

当我创建一个Oracle数据库时,它里面有很多带有奇怪名称的表.这些表是什么？我应该保留它们吗？如果没有,我怎么能避免创建它们？

这些是表名:

LOGMNR_UID $ LOGMNR_SESSION_EVOLVE $ LOGMNR_GLOBAL $ LOGMNR_RESTART_CKPT_TXINFO $ LOGMNR_AGE_SPILL $ LOGMNR_SPILL $ LOGMNRC_DBNAME_UID_MAP LOGMNR_LOG $ LOGMNR_ERROR $ LOGMNR_PROCESSED_LOG $ LOGMNR_FILTER $ LOGMNR_RESTART_CKPT $ LOGMNR_GT_TAB_INCLUDE $ LOGMNR_GT_USER_INCLUDE $ LOGMNRT_MDDL $ OL $ OL $ HINTS OL $ NODES LOGMNR_DICTSTATE $ LOGMNRC_GTLO LOGMNRC_GTCS LOGMNRC_GSII LOGMNR_SEED $ LOGMNR_DICTIONARY $ LOGMNR_OBJ $ LOGMNR_TAB $ LOGMNR_COL $ LOGMNR_ATTRCOL $ LOGMNR_TS $ LOGMNR_IND $ LOGMNR_USER $ LOGMNR_TABPART $ LOGMNR_TABSUBPART $ LOGMNR_TABCOMPART $ LOGMNR_TYPE $ LOGMNR_COLTYPE $ LOGMNR_ATTRIBUTE $ LOGMNR_LOB $ LOGMNR_CDEF $ LOGMNR_CCOL $ LOGMNR_ICOL $ LOGMNR_LOBFRAG $ LOGMNR_INDPART $ LOGMNR_INDSUBPART $ LOGMNR_INDCOMPART $ LOGMNR_LOGMNR_BUILDLOG LOGMNR_NTAB $ LOGMNR_OPQTYPE $ LOGMNR_SUBCOLTYPE $ LOGMNR_KOPM $ LOGMNR_PROPS $ LOGMNR_ENC $LOGMNR_REFCON $ LOGMNR_PARTOBJ $ LOGMNRP_CTAS_PART_MAP LOGSTDBY $ APPLY_PROGRESS MVIEW $ _ADV_OWB DEF $ _AQERROR DEF $ _AQCALL MVIEW $ _ADV_PARTITION MVIEW $ _ADV_INDEX HELP SQLPLUS_PRODUCT_PROFILE LOGSTDBY $历史LOGSTDBY $ SKIP_SUPPORT LOGSTDBY $ SKIP LOGSTDBY $ SKIP_TRANSACTION LOGSTDBY $ PLSQL LOGSTDBY $ FLASHBACK_SCN LOGSTDBY $ SCN LOGSTDBY $ APPLY_MILESTONE LOGSTDBY $ EVENTS LOGSTDBY $参数REPCAT $ _SITES_NEW REPCAT $ _EXTENSION REPCAT $ _INSTANTIATION_DDL REPCAT $ _EXCEPTIONS REPCAT $ _TEMPLATE_TARGETS REPCAT $ _RUNTIME_PARMS REPCAT $ _SITE_OBJECTS REPCAT $ _TEMPLATE_SITES REPCAT $ _USER_PARM_VALUES REPCAT $ _OBJECT_PARMS REPCAT $ _TEMPLATE_PARMS REPCAT $ _TEMPLATE_OBJECTS REPCAT $ _TEMPLATE_REFGROUPS REPCAT $ _OBJECT_TYPES REPCAT $ _USER_AUTHORIZATIONS REPCAT $ _REFRESH_TEMPLATES REPCAT $ _TEMPLATE_TYPES REPCAT $ _TEMPLATE_STATUSREPCAT $ _FLAVOR_OBJECTS REPCAT $ _AUDIT_COLUMN REPCAT $ _AUDIT_ATTRIBUTE REPCAT $ _PARAMETER_COLUMN REPCAT $ _RESOL_STATS_CONTROL REPCAT $ _RESOLUTION_STATISTICS REPCAT $ _RESOLUTION REPCAT $ _RESOLUTION_METHOD REPCAT $ _Conflict REPCAT $ _GROUPED_COLUMN REPCAT $ _COLUMN_GROUP REPCAT $ _PRIORITY REPCAT $ _PRIORITY_GROUP REPCAT $ _REPGROUP_PRIVS REPCAT $ _DDL REPCAT $ _REPCATLOG REPCAT $ _REPPROP REPCAT $ _GENERATED REPCAT $ _KEY_COLUMNS REPCAT $ _REPCOLUMN REPCAT $ _REPOBJECT REPCAT $ _SNAPGROUP REPCAT $ _REPSCHEMA REPCAT $ _FLAVORS REPCAT $ _REPCAT DEF $ _PUSHED_TRANSACTIONS DEF $ _ORIGIN DEF $ _PROPAGATOR DEF $ _TEMP $ LOB DEF $ _LOB DEF $ _DEFAULTDEST DEF $ _CALLDEST DEF $ _DESTINATION DEF $ _ERROR AQ $ _INTERNET_AGENT_PRIVS AQ $ _INTERNET_AGENTS AQ $ _SCHEDULES AQ $ _QUEUES AQ $ _QUEUE_TABLES MVIEW $ _ADV_PLAN MVIEW $ _ADV_JOURNAL MVIEW $ _ADV_INFO MVIEW $ _ADV_PARAMETERSMVIEW $ _ADV_EXCEPTIONS MVIEW $ _ADV_OUTPUT MVIEW $ _ADV_ELIGIBLE MVIEW $ _ADV_CLIQUE MVIEW $ _ADV_GC MVIEW $ _ADV_FJG MVIEW $ _ADV_AJG MVIEW $ _ADV_ROLLUP MVIEW $ _ADV_LEVEL MVIEW $ _ADV_FILTERINSTANCE MVIEW $ _ADV_LOG MVIEW $ _ADV_FILTER MVIEW $ _ADV_TEMP MVIEW $ _ADV_PRETTY MVIEW $ _ADV_SQLDEPEND MVIEW $ _ADV_BASETABLE MVIEW $ _ADV_WORKLOAD LOGMNR_SESSION $ LOGMNR_PARAMETER $

Answer 1

您列出的表与Oracle的LogMiner实用程序,物化视图和高级复制等相关.你应该留下这些.

Answer 2

它被称为数据字典,Oracle将信息存储在其模块和表中.请参阅Oracle文档.

如果选择自定义安装,则可以选择不安装模块.这样可以减少模块数量,减少数据字典.
