Oracle 12c如何查看CDB&PDBs信息

这篇文章给大家分享的是有关Oracle 12c如何查看CDB&PDBs信息的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。V$，GV$，CDB_，CONTAINER_DATA的属性决定了对哪些PDB可见；每个容器数据对象都有CON_ID列，列值代表整个CDB可见，1代表root对象，2代表seed对象,3~254代表PDB对象；以下视图的行为不同于其他[G]V$视图:
[G]V$SYSSTAT
[G]V$SYS_TIME_MODEL
[G]V$SYSTEM_EVENT
[G]V$SYSTEM_WAIT_CLASS从root查询时，这些视图返回实例范围的数据，返回的每一行CON_ID列中都有。但是，您可以查询与其他容器数据对象行为相同的等效视图。以下视图可以为CDB中的每个容器返回特定的数据:[G]V$CON_SYSSTAT、[G]V$CON_SYS_TIME_MODEL、[G]V$CON_SYSTEM_EVENT和[G]V$CON_SYSTEM_WAIT_CLASS。Table 43-2 Views for a CDBViewDescriptionContainer data objects, including:l

This view is also used to display information generated by executingDBMS_PDB.CHECK_PLUG_COMPATIBILITY.{USER|ALL|DBA|CDB}_OBJECTSDisplays information about database objects, and theSHARINGcolumn shows whether a database object is a metadata-linked object, an object-linked object, or a standalone object that is not linked to another object.{ALL|DBA|CDB}_SERVICESDisplays information about database services, and thePDBcolumn shows the name of the PDB associated with each service.{USER|ALL|DBA|CDB}_VIEWS{USER|ALL|DBA|CDB}_TABLESTheCONTAINER_DATAcolumn shows whether the view or table is a container data object.{USER|ALL|DBA|CDB}_USERSTheCOMMONcolumn shows whether a user is a common user or a local user.{USER|ALL|DBA|CDB}_ROLES{USER|ALL|DBA|CDB}_COL_PRIVS{USER|ALL}_COL_PRIVS_MADE{USER|ALL}_COL_PRIVS_RECD{USER|ALL}_TAB_PRIVS_MADE{USER|ALL}_TAB_PRIVS_RECD{USER|DBA|CDB}_SYS_PRIVS{USER|DBA|CDB}_ROLE_PRIVSROLE_TAB_PRIVSROLE_SYS_PRIVSTheCOMMONcolumn shows whether a role or privilege is commonly granted or locally granted.{USER|ALL|DBA|CDB}_ARGUMENTS{USER|ALL|DBA|CDB}_CLUSTERS{USER|ALL|DBA|CDB}_CONSTRAINTS{ALL|DBA|CDB}_DIRECTORIES{USER|ALL|DBA|CDB}_IDENTIFIERS{USER|ALL|DBA|CDB}_LIBRARIES{USER|ALL|DBA|CDB}_PROCEDURES{USER|ALL|DBA|CDB}_SOURCE{USER|ALL|DBA|CDB}_SYNONYMS{USER|ALL|DBA|CDB}_VIEWSTheORIGIN_CON_IDcolumn shows the ID of the container from which the row originates.[G]V$DATABASEDisplays information about the database from the control file.
